    A survey on the infestation of dermatophytosis caused by T. tonsurans was made by inquiry to dermatologists. Patients strongly suggestive of having skin lesions due to T. tonsurans were seen in all areas examined, and were mainly schoolboys, including those practicing judo, of high schools and junior high schools. In Nagasaki, a mycological examination was done on 21 judo students and their teacher in a high school in which a patient with T. tonsurans infection was mycologically confirmed and treated by antimycotics. Mycological examinations failed to isolate T. tonsurans, but even after the examination sporadic cases were reported among the group members. In Saga prefecture, Kyushu, a mycological screening for T. tonsurans infection among judoists and wrestlers in 13 high-schools and 7 junior high schools was done using the blush sampling method. Fifty-six strains of T. tonsurans were isolated from 248 students. The problems concerning the control of this infection were discussed.

    `Niho plutonic composite rocks` distributed in Niho Kamigo area in the northeast of Yamaguchi-city in Japan. It is small plutonic composite rocks, of about 2 km in long length and 1 km of short length. The rocks were studied by the geological survey. Many kinds of rock and rare earth elements were determined. The constitution process is estimated by these results. It consists of gabbro-quartz diorite-tonalite{center_dot}granodiorite-granito. The more inside of rock existed, the more felsic rock are discovered. Chemical compositions were TiO{sub 2}, FeO, MnO and K{sub 2}O. It is estimated that intrusion of tonalite and successive intrusion of granodiorite generated and then formed in situ crystallization differentiation. (S.Y.)

    Diversity of bacteria was studied in deep-sea sediments from the Shikoku Basin in the Northwest Pacific Ocean by PCR, RFLP and sequence analysis of 16S rDNA and comparing with Genbank database. Based on the RFLP profile generated, 77 clones from the 16S rDNA library were divided into 27 types. Phylogenetic analysis showed that the 27 independent clones fell into four groups: Proteobacteria (62.96%), Chloroflexi (14.81%), Planctomycetes (14.81%) and Acidobacteria (7.41%). Among all sequenced clones, 6 were related to the sulfur or sulfate metabolism bacteria and the results also demonstrated that some bacteria in deep-sea sediments had relation to matter-energy circulation.

    This paper proposes solar farm, a system suitable for China`s present circumstances, and describes its development plan. In this plan, agriculture and stock farming are promoted through irrigation using PV power in the desert zone, middle-east China. In addition, electric power is produced by laying PV power generation modules. The solar farm has 100 blocks of farmland equivalent to 700 ha, which includes 300 farmhouses (population of 1200). It can be a food supply base producing rice and wheat. The power generation capacity is at least 1000 kW, and the night power is supplied by battery installed in each farmhouse. The power generated in the daytime is used not only for agriculture but also for secondary industry such as processing of agricultural and stock farming products. The Chinese government requires 300,000 ha of farmland development every year up to 2030, the peak of population. When a half of this is developed by the solar farm, 200 solar farms are to be developed every year. For 30 years, 6000 solar farms are to be developed. 5 refs., 1 fig., 1 tab.

  7. Thermal structure of pumpellyite-actinolite facies regions in the Sanbagawa belt, Shikoku, SW Japan

    On the basis of the mineral assemblages of pelitic rocks, the Sanbagawa belt in Shikoku, SW Japan, has been divided, from low- to high-grade parts, into the chlorite, garnet, albite-biotite and oligoclase-biotite zones (Higashino, 1990). Also, the mineral assemblage of pumpellyite + actinolite + epidote + chlorite or epidote + actinolite + hematite + chlorite, which defines the pumpellyite-actinolite (PA) facies (e.g., Banno, 1998), is widely recognized in metabasites in the chlorite zone (e.g. Banno & Sakai, 1989). However, the detailed study on the PA facies regions has been done only in the Omoiji-Nagasawa area (Nakajima et al., 1977) and Asemigawa-Shirataki area (Nakajima, 1982) in central Shikoku, and thus, it is still hard to solve the regional thermal structure of the PA facies region. This study is aimed to reveal the thermal structure of the PA facies region of the Sanbagawa belt in Shikoku by analyzing the mineral assemblages and mineral chemistries of metabasites from the nine newly studied areas. The studied areas studied belong to the chlorite zone in the Oboke and Besshi units; the Oboke unit structurally underlay the Besshi unit. The mineral assemblages include pumpellyite + epidote + actinolite, epidote + actinolite _ hematite and epidote + Na-amphibole + actinolite + hematite. The metabasites from some areas involve Na-pyroxene-bearing assemblages, but the analyses of the Schreinemakers bundle of Tagiri et al. (1992) show that these assemblages do not define the Na-pyroxene-chlorite subfacies. As the low-grade metamorphic rocks do not have the hematite + pumpellyite paragenesis, its metamorphic temperature is estimated to be higher than the discontinuous reaction temperature of pumpellyite + hematite + quartz = epidote + actinolite + H2O, as shown by Nakajima et al. (1977). It is difficult to detect the difference in temperature in the PA facies regions by analyzing mineral assemblages. To detect the difference in temperature, and then to reveal

    A 3 day rally was held in August 1999 in the city of Shikoku, Japan to bring electric vehicles (EVs) to the public's attention. A total of 39 EVs from 3 production series participated. This included 29 EVs converted from internal combustion engine vehicles, 5 prototype EVs and 2 hybrid electric vehicles. Thirty seven of the EVs used lead-acid batteries, one used nickel-metal hydride batteries and one used lithium-ion batteries. Each one was charged using one outlet of 3 phase 200 V, 1 phase 200 V or 1 phase 100 V at temporary charging facilities. The 340 km course ran through the city and in mountainous regions. The EVs were driven according to normal traffic rules. At the end of the rally, each EV was evaluated for their performance, hill climbing ability, and re-charging time. Several of the converted EVs drove for more than 50 km through mountainous regions using lead-acid batteries. It was determined that the poor range of EVs can be improved by an efficient daily re-charge. refs.

    We present data from sediment cores collected from IODP Site C0012 in the Shikoku Basin. Our site lies at the Nankai Trough, just prior to subduction of the 19 Ma Philippine Sea plate. Our data indicate that the sedimentary package is undergoing multiple routes of electron transport and that these differing pathways for oxidant supply generate a complex array of metabolic routes and microbial communities involved in carbon cycling. Numerical simulations matched to pore water data document that Ca(2+) and Cl(1-) are largely supplied via diffusion from a high-salinity (44.5 psu) basement fluid, which supports the presence of halophile Archean communities within the deep sedimentary package that are not observed in shallow sediments. Sulfate supply from basement supports anaerobic oxidation of methane (AOM) at a rate of ~0.2 pmol cm(-3) day(-1) at ~400 mbsf. We also note the disappearance of δ-Proteobacteria at 434 mbsf, coincident with the maximum in methane concentration, and their reappearance at 463 mbsf, coinciding with the observed deeper increase in sulfate concentration toward the basement. We did not, however, find ANME representatives in any of the samples analyzed (from 340 to 463 mbsf). The lack of ANME may be due to an overshadowing effect from the more dominant archaeal phylotypes or may indicate involvement of unknown groups of archaea in AOM (i.e., unclassified Euryarchaeota). In addition to the supply of sulfate from a basement aquifer, the deep biosphere at this site is also influenced by an elevated supply of reactive iron (up to 143 μmol g(-1)) and manganese (up to 20 μmol g(-1)). The effect of these metal oxides on the sulfur cycle is inferred from an accompanying sulfur isotope fractionation much smaller than expected from traditional sulfate-reducing pathways. The detection of the manganese- and iron-reducer γ-Proteobacteria Alteromonas at 367 mbsf is consistent with these geochemical inferences.

    Background Seawater temperature is the main factor restricting shallow-water zooxanthellate coral reefs to low latitudes. As temperatures increase, coral species and perhaps reefs may move into higher-latitude waters, increasing the chances of coral reef ecosystems surviving despite global warming. However, there is a growing need to understand the structure of these high-latitude coral communities in order to analyze their future dynamics and to detect any potential changes. Methodology/Principal Findings The high-latitude (32.75°N) community surveyed was located at Tatsukushi, Shikoku Island, Japan. Coral cover was 60±2% and was composed of 73 scleractinian species partitioned into 7 functional groups. Although only 6% of species belonged to the ‘plate-like’ functional group, it was the major contributor to species coverage. This was explained by the dominance of plate-like species such as Acropora hyacinthus and A. solitaryensis. Comparison with historical data suggests a relatively recent colonization/development of A. hyacinthus in this region and a potential increase in coral diversity over the last century. Low coverage of macroalgae (2% of the benthic cover) contrasted with the low abundance of herbivorous fishes, but may be reasonably explained by the high density of sea urchins (12.9±3.3 individuals m−2). Conclusions/Significance The structure and composition of this benthic community are relatively remarkable for a site where winter temperature can durably fall below the accepted limit for coral reef development. Despite limited functionalities and functional redundancy, the current benthic structure might provide a base upon which a reef could eventually develop, as characterized by opportunistic and pioneer frame-building species. In addition to increasing seawater temperatures, on-going management actions and sea urchin density might also explain the observed state of this community. A focus on such ‘marginal’ communities should be a

    The three-dimensional seismic attenuation structure (frequency-independent Q) beneath southwestern Japan was analyzed using t* estimated by applying the S coda wave spectral ratio method to the waveform data from a dense permanent seismic network. The seismic attenuation (Qp-1) structure is clearly imaged for the region beneath Shikoku, the Kii peninsula, and eastern Kyushu at depths down to approximately 50 km. At depths of 5 to 35 km, the seismic attenuation structure changes at the Median tectonic line and other geological boundaries beneath Shikoku and the southwestern Kii peninsula. High-Qp zones within the lower crust of the overlying plate are found just above the slip regions at the centers of the long-term slow-slip events (SSEs) beneath the Bungo and Kii channels and central Shikoku. Beneath central Shikoku, within the overlying plate, a high-Qp zone bounded by low-Qp zones is located from the land surface to the plate interface of the subducting plate. The high-Qp zone and low-Qp zones correspond to high-Vp and low-Vp zones of previous study, respectively. The boundaries of the high- and low-Qp zones are consistent with the segment boundaries of tremors (segment boundaries of short-term SSEs). These results indicated that the locations of the long- and short-term SSEs could be limited by the inhomogeneous distribution of the materials and/or condition of the overlying plate, which is formed due to geological and geographical process. The heterogeneity of materials and/or condition within the fore-arc crust possibly makes an effect on inhomogeneous rheological strength distribution on the interface.

  14. Numerical modeling of short-term slow slip events in the Shikoku region considering the effect of earth tides and plate configuration

    Several studies reported that occurrence of slow slip events (SSEs) in the Nankai region is affected by earth tides (e.g., Nakata et al., 2008; Ide and Tanaka, 2014; Yabe et al., 2015). The tidal effect on the SSEs is also examined by numerical studies (e.g., Hawthorne and Rubin, 2013). In our previous study, repeating SSEs in the Shikoku region are numerically reproduced, incorporating the actual plate configuration (Matsuzawa et al., 2013). In this study, we examined the behavior of SSEs in the Shikoku region, considering stress perturbation by earth tides. Our numerical model is similar to our previous study (Matsuzawa et al., 2013). A plate interface is expressed by small triangular elements. A rate- and state-dependent friction law (RS-law) with cutoff velocities is adopted as the friction law on each element. We assumed that (a-b) value in the RS-law is negative within the short-term SSE region, and positive outside the region. The short-term SSE region is based on the actual distribution of low-frequency tremor. Low effective normal stress is assumed at the depth of short-term SSEs. Calculating stress change by earth tides as in Yabe et al., (2015), we assume that the stress change is represented by periods of 10 major tides. Incorporating this stress perturbation, we calculate the evolution of slip on the plate interface. In the numerical result, repeating short-term SSEs are reproduced in the short-term SSE region. Recurrent intervals of SSEs at an isolated patch (e.g., northeastern Shikoku) have small fluctuation. Introducing tidal effect, peak velocity becomes faster than that in the case without tidal effect. On the other hand, the difference of peak velocities is not clear between the cases with and without tidal effect at widely connected SSE region (e.g., western Shikoku), as the intervals and peak velocities of SSEs are largely fluctuated in both cases. Hirahara (2016) suggested that the recurrence interval of events is synchronized to the period of

    Arc volcanism in the Izu-Ogasawara arc is separated into first and latter term at the separate of Shikoku Basin. Middle to late Eocene early arc volcanism formed a vast terrane of boninites and island arc tholeiites that is unlike active arc systems. A following modern-style arc volcanism was active during the Oligocene, along which intense tholeiitic and calc-alkaline volcanism continued until 29Ma, before spreading of the back- arc basin. The recent arc volcanism in the Izu-Ogasawara arc have started in the middle Miocene, and it is assumed that arc volcanism were decline during spreading of back-arc basin. In the northern Kyushu-Palau Ridge, submarine bottom materials were dredged during the KT95-9 and KT97-8 cruise by the R/V Tansei-maru, Ocean Research Institute, university of Tokyo, and basaltic to andesitic volcanic rocks were recovered during both cruise except for Komahashi-Daini Seamount where recovered acidic plutonic rocks. Komahashi-Daini Seamount tonalite show 37.5Ma of K-Ar dating, and this age indicates early stage of normal arc volcanism. These volcanic rocks are mainly cpx basalt to andesite. Two pyroxene basalt and andesite are only found from Miyazaki Seamount, northern end of the Kyushu-Palau Ridge. Volcanic rocks show different characteristics from first term volcanism in the Izu-Ogasawara forearc rise and recent arc volcanism. The most characteristic is high content of incompatible elements, that is, these volcanics show two to three times content of incompatible elements to Komahashi-Daini Seamount tonalite and former normal arc volcanism in the Izu outer arc (ODP Leg126), and higher content than recent Izu arc volcanism. This characteristic is similar to some volcanics at the ODP Leg59 Site448 in the central Kyushu- Palau Ridge. Site448 volcanic rocks show 32-33Ma of Ar-Ar ages, which considered beginning of activity of Parece Vela Basin. It is considered that the dredged volcanic rocks are uppermost part of volcanism before spreading of

    Three ODP and IODP drilling transects have been completed across the Nankai Trough subduction zone: Ashizuri, Muroto, and Kumano. An essential component of each transect is the so-called "reference site" seaward of the trench (ODP Sites 1173 and 1177; IODP Sites C0011 and C0012). These Shikoku Basin deposits are unusually heterogeneous, which means that virtually all types of frictional, geotechnical, and hydrogeological properties (including pore pressure) vary in 3-D both landward and seaward of the subduction front. By integrating drilling results from the three transects, we recognize the following basin-wide highlights: (1) Boundaries between lithologic units are not time-correlative. As an example, the base of the upper Shikoku Basin unit (hemipelagic/pyroclastic facies) varies in age from 7.8 Ma (C0012) to 3.3 Ma (1173). (2) A basin-wide boundary caused by diagenesis of dispersed volcanic glass shifts its stratigraphic position, with host-sediment ages that range from 5.2 Ma (C0011) to 3.3 Ma (1173). This reaction is important because it affects both porosity and interstitial water geochemistry prior to subduction. (3) Units of siliciclastic and volcaniclastic turbidites occur at middle to lower depths of the stratigraphy, but they cannot be correlated from the west to the east side of the basin. Activity within those channelized and sheet-flow turbidite systems was sensitive to changes in detrital provenance, as well as autocyclic and allocyclic forcing. (4) Clay mineral assemblages changed consistently through time. Muds deposited during the early and middle Miocene are highly enriched in smectite (>45 wt-% of bulk mud), which maximizes volumetric fluid production as strata move down the plate interface and experience smectite dehydration. (5) Because of unusually high heat flow, smectite-to-illite diagenesis begins outboard of the subduction front along the Muroto transect. That local effect of S=>I diagenesis obscures the basin-wide temporal trends in

    Radioactive fission product {sup 131}I released from the Fukushima Daiichi Nuclear Power Plants (FD-NPP) was first detected on March 23, 2011 in an airborne aerosol sample collected at Tokushima, Shikoku Island, located in western Japan. Two other radioactive fission products, {sup 134}Cs and {sup 137}Cs were also observed in a sample collected from April 2 to 4, 2011. The maximum specific radioactivities observed in this work were about 2.5 to 3.5 mBq×m{sup -3} in a airborne aerosol sample collected on April 6. During the course of the continuous monitoring, we also made our first observation of seasonal Asian Dust and those fission products associated with the FDNPP accident concurrently from May 2 to 5, 2011. We found that the specific radioactivities of {sup 134}Cs and {sup 137}Cs decreased drastically only during the period of Asian Dust. And also, it was found that this trend was very similar to the atmospheric elemental concentration (ng×m{sup -3}) variation of stable cesium ({sup 133}Cs) quantified by elemental analyses using our developed ICP-DRC-MS instrument.

  18. Slow slip events in the Kii Peninsula and Shikoku, Japan detected by strain changes at the integrated observatories of Geological Survey of Japan, AIST

    In 2006, Geological Survey of Japan (GSJ), National Institute of Advanced Industrial Science and Technology (AIST) started constructing integrated observatories in and around Shikoku and Kii Peninsula, Japan for research on the Tonankai and Nankai earthquakes. Two observatories were constructed at Kii Peninsula in June 2007, and ten were completed in January 2009. Each observatory has three wells where water temperature, water level (pressure) and ground motion are observed. At one of the three wells, crustal strain is also observed by a multi-component borehole strain meter. According to Automatic Tremor Monitoring System (ATMOS) of Hiroshima University, 11 tremor activities have occurred in the Kii Peninsula since June 2007. We detected strain changes related to these tremor activities. The changes can be explained by short-term slow slip events (SSEs) occurring at several segments of the plate boundary, whose locations are consistent with the tremor activities (e.g. Itaba et al., 2009a). We analyzed these SSEs with the forward method in consideration of locations of the tremors. On the other hand, the observation suggested the existence of SSEs before or without the tremors (e.g. Fukuda and Sagiya, 2008; Itaba et al., 2009b). Therefore, it is important to detect SSEs just by strain changes. We tried to decide the fault planes for SSEs only using the strain data of the observatories of AIST. Since it is difficult to detect strain changes related to SSEs at two or more observatories of AIST, we decided the fault plain by a grid-search method. As a result, the fault plains for SSEs were consistent with the locations of the tremors. References Fukuda, M. and T.

    Seasonal and spatial variations in major ion chemistry and isotope composition in the rural-urban catchment of the Shigenobu River were monitored to determine the influences of agricultural and urban sewage systems on water quality. Temporal patterns of biochemical oxygen demand (BOD), total nitrogen (TN), total phosphorus (TP), and suspended sediment (SS) were examined at four sites in the rural-urban catchment. Urban land cover, incorporating the effects of increased population, domestic water use, and industrial wastewater, was positively associated with increases in water pollution and was included as an important explanatory variable for the variations in all water quality parameters. Significant trends were found in each parameter. BOD concentrations ranged widely, and were high in urban regions, due to the presence of a waste water treatment plant. TN and SS showed various trends, but did not vary widely, unlike TP. TP concentrations varied greatly, with high concentrations in cultivated areas, due to fertilizer use. Local water quality management or geology could further explain some of the variations in water quality. Non-point-source pollution exhibited strong positive spatial autocorrelation, indicating that incorporating spatial dimensions into water quality assessment enhances our understanding of spatial patterns of water quality. Data from the Ministry of Land Infrastructure and Transport (MLIT) and Environment Ministry (EM) were used to investigate trends in land management. Stepwise regression analysis was used to test the correlation between specific management practises and substance concentrations in surface water and sediment. MLIT and EM data for 1981-2003 showed an increase in TN, TP, and SS concentrations in surface water. High levels of fertilizer in dormant sprays and domestic water use were associated with high pesticide concentrations in water and sediment. This paper presents a novel method of studying the environmental impact of

Is it a historical road we must follow?Human being had experienced a long history of living on collection and hunting for about 2,000 to 3,000 millenniums since human being appeared on earth. After we settled down, another 10 millenniums passed. Human being began to cultivate crops and raise animals. Thus, we entered the primitive agriculture stage.

    2015-06-01

    Full Text Available Biodynamic agriculture is undoubtedly the oldest organized agricultural movement in the world. It is considered as an organic agricultural farming approach and determined as the oldest organized alternative agricultural movement in the world. In 1924 Rudolf Steiner – an Austrian natural scientist and philosopher, carried out a series of eight lectures in Koberwitz, currently Kobierzyce- Poland, where he formulated his visions on changes in agriculture and revealed his spiritual and scientific concepts about the connection between nature and agriculture by determining the important role of agriculture for the future of humanity and thus he became known as “the father of anthroposophy”. The great ecological effect of the application of the biodynamic agriculture is expressed in soil preservation and preservation of the living organisms in the soil, as well as maintenance of the natural balance in the vegetable and animal kingdom.

    Full Text Available Problem statement: Considering unsustainable agricultural conditions of Iran and organizational recession and inability of current extension organization to achieve sustainability, it seems that extension systems require a new organizational structure to achieve sustainability objectives. The purpose of the present study was to identify the most appropriate characteristics for extension organization toward green agriculture in Iran context. Approach: To fulfill this objective, a sample of 120 respondents was selected through simple random sampling technique. A survey study was applied as a methodology of research. A mailed questionnaire was used to collect the data. The response rate of questionnaire was 65.83% (N = 79. Appropriate descriptive statistics such as mean scores, standard deviations and variation ratio were used. Results: Extension experts believed that among important organizational characteristics of extension system for supporting green agriculture collaboration among research, extension, education organizations, farmers' associations, NGOs, rural credit agencies, transportation companies, considering local groups and learning organization had very high importance for supporting green agriculture. According to factor analysis, the implications for extension organization were categorized into two groups consisting: (1 Holistic organizations (2 Participatory organizations that those factors explained 67.54% of the total variance of the research variables. Conclusion: Identifying suitable extension mechanisms had important role for developing extension system. Therefore, identifying extension organizational characteristics for supporting green agriculture of Iran is one of the major approaches needs to be carefully thought and accurately implemented for the extension system development.

  9. MODERNIZATION OF AGRICULTURE VS SUSTAINABLE AGRICULTURE

    Directory of Open Access Journals (Sweden)

    Dariusz KUSZ

    2014-04-01

    Full Text Available The paper shows the correlation between the need to modernise agriculture and sustainable development. Modernisation of agriculture aiming only at increasing the efficiency of production, if implemented in accordance with the principles of sustainable development, enabled reduction in the negative external effects. Modernisation of agriculture is supposed to ensure productivity growth without imposing any threats to the natural environment and the well-being of animals, reduced impoverishment in rural areas as well as to ensure food security, growth in the profitability of farms, improvement to the efficiency of use of natural resources. Therefore, in the near future, the agriculture – environment relation will be subject to change taking into account, on the one hand, concern about the natural environment, and, on the other, pressure on increasing the efficiency of production. The above challenges will be addressed by the need to implement efficient and, at the same time, environmentally-friendly production technologies and relevant legal instruments which oblige agricultural producers to protect the natural environment.

    Full Text Available After becoming self-standing state one of new needs of Croatia important for agricultural profession, farmers, policy makers and public needs was regionalization of agriculture. It is the analyse of state of agroecological conditions in agrosphere and based on results identification and territorial separation of agricultural regions as parts of agrosphere with similar conditions for plant and animal growing and similar farming systems. On this track within a special project we fi nished an inventory of agrosphere, result of which is Regionalisation of Croatian Agriculture presented in this paper. Following wise message of old Chinese proverb cited above, the starting approach is the MFCAL concept (Multifunctional Character of Agriculture and Land, which means that apart from very important and primary economic, agriculture and agricultural land (soil in human life play other roles (functions of similar importance; environmental, social, cultural and spatial, as well as the role of shaping the cultural landscape as a factor of rural development. As well, we respect the point of view prevailing in EU that all natural resources used in agriculture but at the fi rst place soil as a major one, need sustainable use and efficient protection. Using the data on Land resource potential based primarily on data of General Soil Map of Croatia (GSM in a scale of 1:50 000 and results of our research in the period 2000 – 2003, the agrosphere of Croatia is divided in three agricultural regions; Pannonian with four, Mountain with two and Adriatic with three subregions.

  17. Clustering of agricultural enterprises

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Agricultural business is a very specific branch which is characterized by very low financial performance while this characteristic is given mainly by external factors as market pricing of agricultural commodities on one side, and production costs of agricultural commodities on the other side. This way, agricultural enterprises recognize negative values of gross margin in the Profit and Loss Statement but positive value of operating profit after even there are items of costs which are deducted. These results are derived from agricultural production subsidies which are recognized as income in the P/L Statement. In connection with this fact, the government subsidies are a substantial component of financial performance of agricultural enterprises.Primary research proceeded on the statistical sample of one hundred agricultural companies, has shown that also other specifics influencing financial performance of these businesses exist here. In order to determine the influences, the cluster analysis has been applied at using more than 10 variables. This approach has led to construction of clusters (groups of agricultural business entities with different characteristics of the group. The objective of this paper is to identify the main determinants of financial performance of agricultural enterprises and to determine their influences under different economic characteristics of these business entities. For this purpose, the regression analysis has been subsequently applied on the groups of companies coming out from the cluster analysis. Besides the operating profit which is the main driving force of financial performance measured with the economic value added (EVA in agricultural enterprises, also capital structure and cost of capital have been observed as very strong influences on financial performance but these factors have different directions of their influence on the economic value added under different financial characteristics of agricultural

  9. Biosurfactants in agriculture.

    Science.gov (United States)

    Sachdev, Dhara P; Cameotra, Swaranjit S

    2013-02-01

    Agricultural productivity to meet growing demands of human population is a matter of great concern for all countries. Use of green compounds to achieve the sustainable agriculture is the present necessity. This review highlights the enormous use of harsh surfactants in agricultural soil and agrochemical industries. Biosurfactants which are reported to be produced by bacteria, yeasts, and fungi can serve as green surfactants. Biosurfactants are considered to be less toxic and eco-friendly and thus several types of biosurfactants have the potential to be commercially produced for extensive applications in pharmaceutical, cosmetics, and food industries. The biosurfactants synthesized by environmental isolates also has promising role in the agricultural industry. Many rhizosphere and plant associated microbes produce biosurfactant; these biomolecules play vital role in motility, signaling, and biofilm formation, indicating that biosurfactant governs plant-microbe interaction. In agriculture, biosurfactants can be used for plant pathogen elimination and for increasing the bioavailability of nutrient for beneficial plant associated microbes. Biosurfactants can widely be applied for improving the agricultural soil quality by soil remediation. These biomolecules can replace the harsh surfactant presently being used in million dollar pesticide industries. Thus, exploring biosurfactants from environmental isolates for investigating their potential role in plant growth promotion and other related agricultural applications warrants details research. Conventional methods are followed for screening the microbial population for production of biosurfactant. However, molecular methods are fewer in reaching biosurfactants from diverse microbial population and there is need to explore novel biosurfactant from uncultured microbes in soil biosphere by using advanced methodologies like functional metagenomics.

  10. [Effects of agricultural activities and transgenic crops on agricultural biodiversity].

    Science.gov (United States)

    Zhang, Xi-Tao; Luo, Hong-Bing; Li, Jun-Sheng; Huang, Hai; Liu, Yong-Bo

    2014-09-01

    Agricultural biodiversity is a key part of the ecosystem biodiversity, but it receives little concern. The monoculture, environmental pollution and habitat fragmentation caused by agricultural activities have threatened agricultural biodiversity over the past 50 years. To optimize agricultural management measures for crop production and environmental protection, we reviewed the effects of agricultural activities, including cultivation patterns, plastic mulching, chemical additions and the cultivation of transgenic crops, on agricultural biodiversity. The results showed that chemical pesticides and fertilizers had the most serious influence and the effects of transgenic crops varied with other factors like the specific transgene inserted in crops. The environmental risk of transgenic crops should be assessed widely through case-by-case methods, particularly its potential impacts on agricultural biodiversity. It is important to consider the protection of agricultural biodiversity before taking certain agricultural practices, which could improve agricultural production and simultaneously reduce the environmental impacts.

    2007-06-15

    Musculoskeletal disorders (MSD) are a major area of concern in the occupational world. The agricultural industry is particularly affected: 93 percent of occupational diseases in agriculture are MSD. Carpal tunnel syndrome occurs in one third of the cases. Shoulder is the second most common location. The most affected occupational areas are meat production, viticulture, market gardening, horticulture and small animal farming. This MSD phenomenon, of multifactorial origin, which has been amplifying for two decades, has led to some consensus in terms of definition and prevention strategy. The aim is to identify, limit or even suppress risk factors through worker training as well as through actions related to work organization. Regarding occupational health and safety in agriculture, two fronts of progress have been mentioned: the creation of a statistic observatory of MSD (disease, occupational area and cost) and the assessment of prevention activities. Finally, a new issue is being discussed: sustainable prevention of MSD.

    2000-08-01

    Agriculture is considered one of the most hazardous occupations. Organic dusts and toxic gases constitute some of the most common and potentially disabling occupational and environmental hazards. The changing patterns of agriculture have paradoxically contributed to both improved working conditions and increased exposure to respiratory hazards. Animal confinement operations with increasing animal density, particularly swine confinement, have contributed significantly to increased intensity and duration of exposure to indoor air toxins. Ongoing research has implicated bacterial endotoxins, fungal spores, and the inherent toxicity of grain dusts as causes of upper and lower airway inflammation and as immunologic agents in both grain and animal production. Animal confinement gases, particularly ammonia and hydrogen sulfide, have been implicated as additional sources of respiratory irritants. It has become evident that a significant percentage of agricultural workers have clinical symptoms associated with long-term exposure to organic dusts and animal confinement gases. Respiratory diseases and syndromes, including hypersensitivity pneumonitis, organic dust toxic syndrome, chronic bronchitis, mucous membrane inflammation syndrome, and asthmalike syndrome, result from ongoing acute and chronic exposures. In this review we focus upon the emerging respiratory health issues in a changing agricultural economic and technologic environment. Environmental and occupational hazards and exposures will be emphasized rather than clinical diagnosis and treatment. Methods of prevention, from both engineering controls and personal respiratory perspectives, are also addressed.

    Full Text Available Agriculture in India has directly or indirectly continued to be the source of livelihood to majority of the population. Indian agriculture has seen a lot of changes in its structure. India, predominantly an agricultural economy, has healthy signs of transformation in agriculture and allied activities. India has seen agriculture as a precious tool of economic development as other sectors of production depend on it. Efficient backward and forward integration with agriculture has led to globally competitive production system in terms of cost and quality. Cooperatives seem to be well positioned to coordinate product differentiation at the farm level and to integrate forward into value added processing activities.. Indian agriculture can be balanced and made efficient through proper and better management practices. The present study brings out past and present scenario of agricultural marketing prevailing in India, its challenges and future recommendations. Moreover the opportunities provide by agricultural marketing should be tapped effectively by the marketers.

  20. Researches on Agricultural Cooperative Economic Organization Promoting Agricultural Insurance Development

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    The advantages of cooperative economic organization being the effective carrier of agricultural insurance development are analyzed. Firstly, cooperative economic organization promotes scale management and solves the problem of decentralized operation of small households. Secondly, cooperative economic organization can settle the problem of peasants’ low systematization. Thirdly, cooperative economic organization can largely reduce the costs of agricultural insurance operation. Fourthly, cooperative organization decreases moral risks as well as adverse selection to some extent. Lastly, cooperative organization, to a certain degree, reduces the risks of agricultural production and increases the insurability of agricultural risks. Meanwhile, limitations of agricultural cooperative economic organization being the carrier of agricultural insurance operation are pointed out. Firstly, cooperative economic organization has limited coverage and small size of organization, which is harmful to the diversification of agricultural risks. Secondly, cooperative economic organization lacks capital funds and its development is not standard, which is not perfect for the function exertion as a carrier. Lastly, members of professional cooperative organization have low cultural qualities, which restrict the implementation of agricultural insurance. The modes of farmers’ cooperative economic organization promoting agricultural insurance development are proposed, including mode of agricultural insurance cooperative ( mutual corporation), mode of "leading enterprises (companies) + professional cooperative organization (planting majors) + insurance" and mode of professional cooperatives serving as agricultural insurance agent. Last of all, the promoting role of agricultural insurance in agricultural cooperative economic organization is briefly illustrated.

Objective: To analyze the audiological profile of this population, verifying the work's influence on its hearing. Method: It was realized a retrospective, individual, observational, and cross-sectional study through the data obtained by means of a questionnaire and audiometric thresholds of 41 agricultural pilots. To the statistical analysis were utilized the chi-square, Spearman, and Wilcoxon tests with significance level of 5%. Results: It was verified that 95,1% of the pilots use PPE ( personal protective equipment during flight and 58,5% have contact with pesticides. More than half of individuals referred to feel auditory and extra auditory symptoms, being the buzz the more frequent (29,1%. It has the occurrence of 29,3% of NIHL suggestive hearing loss and 68,3% of normality, taking this presence of unilateral notch in 24,4% and bilateral notch in 31,7%. It was found correlation statistically significant in the associations between time of service and the average of the acute frequencies in the right ear (p=0038, and in the left ear (p=0,010. It has a statistical tendency in the association between audiometric configuration and contact with pesticides (p=0,088. Conclusion: The hearing loss prevalence in this study was showed high. More than half of the sample has normal audiometric thresholds with notch configuration. Such data lead to the conclusion that the agricultural pilots, even with PPE use, they still suffer with the damages caused by noise, needing best proposals of hearing loss prevention.

  9. Biostimulants in Agriculture

    Full Text Available Biostimulants, which may be derived from a wide range of natural or synthetic processes, are now widely used in agriculture and yet the mode of action of these materials is not well understood. On the basis of available literature, and based upon the diversity of biostimulant responses highlighted in this focus issue, we hypothesize that biostimulants function by directly interacting with plant signaling cascades or act through stimulation of endophytic and non-endophytic bacteria, yeast and fungi to produce molecules of benefit to the plant. The benefit of the biostimulant is derived from the reduction in assimilates that are diverted to non-productive stress response metabolism.

    Global support for Conservation Agriculture (CA) as a pathway to Sustainable Intensification is strong. CA revolves around three principles: no-till (or minimal soil disturbance), soil cover, and crop rotation. The benefits arising from the ease of crop management, energy/cost/time savings, and soil and water conservation led to widespread adoption of CA, particularly on large farms in the Americas and Australia, where farmers harness the tools of modern science: highly-sophisticated machines, potent agrochemicals, and biotechnology. Over the past 10 years CA has been promoted among smallholder farmers in the (sub-) tropics, often with disappointing results. Growing evidence challenges the claims that CA increases crop yields and builds-up soil carbon although increased stability of crop yields in dry climates is evident. Our analyses suggest pragmatic adoption on larger mechanized farms, and limited uptake of CA by smallholder farmers in developing countries. We propose a rigorous, context-sensitive approach based on Systems Agronomy to analyze and explore sustainable intensification options, including the potential of CA. There is an urgent need to move beyond dogma and prescriptive approaches to provide soil and crop management options for farmers to enable the Sustainable Intensification of agriculture.

    Full Text Available Farms of CSA types are a viable alternative to trade of agricultural products coming from conventional agriculture. These farms are faced with a number of policy issues related to product, price, distribution and promotion. In order to elucidate the issues listed above, we have investigated the literature of specialty. Farmers must make more flexible the content of basket both quantitatively and in terms of the nature of food products offered. Consumers need information on ways of preparation or preservation of products. The growth of the processing degree in farm, and inclusion in the offer of services in ecotourism represent effective options to satisfy consumers. To offset the negative impact of high prices measures should be taken in reducing costs, more flexibility in rescheduling of payments due from customers and compensate for the lack of financial resources with the provision of farm work or subsidize a portion of the basket value from private or government sources. Delivery of baskets should be both at fixed points and at customers domicile. Farmers must provide customers the possibility so that they could harvest themselves the products they will buy. Negative influence of prices will be reduced by establishing an effective communication policy with the market, by organizing events on the farm or nearby towns, through blogs and social networks, and through participation in fairs and exhibitions. A greater customer involvement in farming activities will lead to the implementation of an effective marketing mix.

    Full Text Available Around 52% of the population of India rely on farming for their livelihood which accounts for 17% of India’s GDP. Whilst most farmers are familiar with conventional farming practices, they are often ill positioned to promptly deal with diseases and plant infestations affecting their crops. Current advisory systems tend to be generic and are not tailored to specific plots or farms. This work comprises an agriculture advisory call center similar to a modern call center to provide an agriculture disease mitigation system. The information regarding an individual farm is collected using mobile phones. The image of diseased/infected crop is also captured using mobile phones and is made available to the expert to provide the advisory. To scale the advisory, an attempt is also made to automate the disease recognition process using image processing. Unfortunately, the photos taken will be sensitive to a number of factors including camera type and lighting incident on the scene. Ideally, the images would be processed in such a way as to provide the expert with a visual representation of the affected crops that reflects the true nature of the scene. We describe a framework for standardising the colour of plant images taken using both mobile phones and compact cameras within the context of the advisory system.

    As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security. Several emerging biotechnology approaches were discussed in a recent symposium organized at the 13th IUPAC International Congress of Pesticide Chemistry meeting in San Francisco, CA, USA. This paper summarizes the innovative research and several of the new and emerging technologies within the field of agricultural biotechnology that were presented during the symposium. This discussion highlights how agricultural biotechnology fits within the context of sustainable agriculture and improved food security and can be used in support of further development and adoption of beneficial GM crops.

The lack of necessary guarantees the low profit registered in agricultural district, economy instability and other things had and continue to have a negative impact on the evolution of agricultural sector, this being seen as one with a high level of risk. Commercial banks use less own funds for lending to agriculture and especially when the loans are guaranteed from various funds, programs or foreign donor agencies. Farmers find it difficult to bank loans because of collateral amount required is too high. However, commercial banks in Moldova provide agricultural loans, thus increasing the economic efficiency of agriculture.

    For the electric power companies, the activity of pushing forward the load levelling contributes greatly to the curtailment of cost by means of effective formation and utilization of facilities. It is planned to take up more positive activities with a target of 3% improvement in the load factor in ten years. Concrete measures for further promotion of load levelling are the diversity of the rate menu of appraising the load levelling effort of the customers and the promotion of the spread of equipment and systems relating to load levelling such as electric water heating apparatuses and thermal energy storage air conditioning systems. The rate system has been reviewed taking the opportunity of rate revision made in January, 1996. Particularly, further load shift to midnight time zone is expected as a result of better rate incentive for customers which is brought about by large reduction of the rate level due to the cost reduction effect accompanying the improvement in atomic power generation ratio. Outlines are given on the fields relating to general households, business, dwellings, buildings, and industry. 3 figs., 1 tab.

    Full Text Available Botswana, a middle-income country, is experiencing a sluggish economic growth and a rapid urbanisation which has brought in its wake high unemployment, poverty and food insecurity. This has led some people to engage in subsistence and commercial urban and peri-urban agriculture (UPA to address these problems. However, in spite of its known advantages, uptake of UPA has been low for a number of reasons including: high GDP before the economic meltdown of recent years; a harsh climate; lack of water; poor access to land; and over-reliance on generous government handouts. Nevertheless, the extent of its practice and its contribution to food security – albeit modest – shows that it is a sector that needs to be encouraged and supported. Both central and local government can play a big role by providing land and infrastructure, and also by implementing an enabling policy and regulatory environment which promotes small- and medium-scale urban food production.

    Full Text Available Agriculture is one of the most important economic activities in each country or area, as it is in close correlation with all other the other economic activities, in a whole which must be structured so as to achieve a more efficient planning and organization of the territory. The practice of a traditional agriculture, based on industrialization, affects the natural environment through emissions of pollutants, waste and deforestation which together affects biodiversity. Green Agriculture suppose to empower managers to widespread the use of fertilizers, to improve the crop rotation, to realize a more efficient water consumption, to improve the storage methods and the supply chain of products. Agricultural policies are closely interrelated with environmental policies as agricultural activities have a considerable influence on the environment. The efficiency of agricultural policies is reflected in monetary transfers between agriculture and other economic sectors, in the costs due to the reallocation of the resources between different agricultural and non-agricultural activities and in the realized gains. Currently there is a constant concern of the governments for the transition to a green agriculture, and most countries recognize the importance of achieving sustainable economic development.

    In the real world market, agricultural commodity are imposed with fluctuating prices. This means that the price of agricultural products are relatively volatile, which means that agricultural business is a quite risky business for farmers. This paper presents some mathematical models to model such risks in the form of its volatility, based on certain assumptions. The proposed models are time varying volatility model, as well as time varying volatility with mean reversion and with seasonal mean equation models. Implementation on empirical data show that agricultural products are indeed risky.

    Despite the high and relatively stable overall growth of the economy, India's agriculture sector is underperforming and a vast section of the population remains undernourished. To explore the possible interplay between agricultural performance and malnutrition indicators to see whether states that perform better in agriculture record better nutritional outcomes. Correlation analysis and a simple linear regression model were used to study the relationship between agricultural performance and malnutrition among children under 5 years of age and adults from 15 to 49 years of age at 20 major states using data from the National Family Health Survey-3 for the year 2005/06 and the national accounts. Indicators of the level of agricultural performance or income have a strong and significant negative relationship with indices of undernutrition among adults and children, a result suggesting that improvement of agricultural productivity can be a powerful tool to reduce undernutrition across the vast majority of the population. In addition to agriculture, access to sanitation facilities and women's literacy were also found to be strong factors affecting malnutrition. Access to healthcare for women and child-care practices, in particular breastfeeding within 1 hour after birth, are other important determinants of malnutrition among adults and children. Malnutrition is a multidimensional problem that requires multisectoral interventions. The findings show that improving agricultural performance can have a positive impact on nutritional outcomes. However, improvements in agriculture alone cannot be effective in combating malnutrition if several other mediating factors are not in place. Interventions to improve education, health, sanitation and household infrastructure, and care and feeding practices are critical. Innovative strategies that integrate agriculture and nutrition programs stand a better chance of combating the malnutrition problem.

In this context the study was carried out to ascertain the representation of women and their academic achievement in agricultural education. The study revealed that almost equal representation was found for women in agricultural course and they were also provided better quality education in their schooling, in the form of English medium education and education in private schools. Recent trends for the past four years showed a higher percentage of enrollments of women in agricultural course than men. The growth rate was also higher for the female students. Women also showed a significantly higher percentage of academic achievement than men. These positive indicators provide sufficient signals for equality of women in agricultural course and have positive implications for development of the agricultural sector in future.

    Agricultural lands occupy 37% of the earth's land surface. Agriculture accounts for 52 and 84% of global anthropogenic methane and nitrous oxide emissions. Agricultural soils may also act as a sink or source for CO2, but the net flux is small. Many agricultural practices can potentially mitigate greenhouse gas (GHG) emissions, the most prominent of which are improved cropland and grazing land management and restoration of degraded lands and cultivated organic soils. Lower, but still significant mitigation potential is provided by water and rice management, set-aside, land use change and agroforestry, livestock management and manure management. The global technical mitigation potential from agriculture (excluding fossil fuel offsets from biomass) by 2030, considering all gases, is estimated to be approximately 5500-6000Mt CO2-eq.yr-1, with economic potentials of approximately 1500-1600, 2500-2700 and 4000-4300Mt CO2-eq.yr-1 at carbon prices of up to 20, up to 50 and up to 100 US$ t CO2-eq.-1, respectively. In addition, GHG emissions could be reduced by substitution of fossil fuels for energy production by agricultural feedstocks (e.g. crop residues, dung and dedicated energy crops). The economic mitigation potential of biomass energy from agriculture is estimated to be 640, 2240 and 16 000Mt CO2-eq.yr-1 at 0-20, 0-50 and 0-100 US$ t CO2-eq.-1, respectively.

    Over the coming decades, climate change is likely to pose a major challenge to agriculture; temperatures are rising, rainfall is becoming more variable and extreme weather is becoming a more common event. Researchers and policymakers agree that adapting agriculture to these impacts is a priority for ensuring future food security. Strategies to achieve that in practice tend to focus on modern science. But evidence, both old and new, suggests that the traditional knowledge and crop varieties of indigenous peoples and local communities could prove even more important in adapting agriculture to climate change.

    As Earth's climate warms, agricultural producers will need to adapt. Changes, especially increases in extreme events, are already having an impact on food production, according to speakers at a 1 May session on agriculture and food security at the AGU Science Policy Conference. Christopher Field, director of the Department of Global Ecology at the Carnegie Institution for Science of Washington, D. C., pointed out the complex factors that come into play in understanding food security, including spatially varying controls and stresses, incomplete models, and the potential for threshold responses. Factors that are likely to cause problems include increasing population; increasing preference for meat, which needs more land and energy inputs to produce; climate change; and increasing use of agricultural lands for biomass energy.

    Kumar, Manish; Tomar, Rajesh Singh; Lade, Harshad; Paul, Diby

    2016-07-01

    Excessive use of chemical fertilizers to increase production from available land has resulted in deterioration of soil quality. To prevent further soil deterioration, the use of methylotrophic bacteria that have the ability to colonize different habitats, including soil, sediment, water, and both epiphytes and endophytes as host plants, has been suggested for sustainable agriculture. Methylotrophic bacteria are known to play a significant role in the biogeochemical cycle in soil ecosystems, ultimately fortifying plants and sustaining agriculture. Methylotrophs also improve air quality by using volatile organic compounds such as dichloromethane, formaldehyde, methanol, and formic acid. Additionally, methylotrophs are involved in phosphorous, nitrogen, and carbon cycling and can help reduce global warming. In this review, different aspects of the interaction between methylotrophs and host plants are discussed, including the role of methylotrophs in phosphorus acquisition, nitrogen fixation, phytohormone production, iron chelation, and plant growth promotion, and co-inoculation of these bacteria as biofertilizers for viable agriculture practices.

    Irradiation of food for disinfestation and preservation is increasing in importance because of increasing restrictions on various chemical treatments. Irradiation treatment is of particular interest in the Northwest because of a growing supply of agricultural products and the need to develop new export markets. Several products have, or could potentially have, significant export markets if stringent insect ocntrol procedures are developed and followed. Due to the recognized potential benefits of irradiation, this program was conducted to evaluate the benefits of using irradiation on Northwest agricultural products. Commodities currently included in the program are cherries, apples, asparagus, spices, hay, and hides.

  1. Saline agriculture in Mediterranean environments

    Directory of Open Access Journals (Sweden)

    Albino Maggio

    2011-03-01

    Full Text Available Salinization is increasingly affecting world's agricultural land causing serious yield loss and soil degradation. Understanding how we could improve crop productivity in salinized environments is therefore critical to meet the challenging goal of feeding 9.3 billion people by 2050. Our comprehension of fundamental physiological mechanisms in plant salt stress adaptation has greatly advanced over the last decades. However, many of these mechanisms have been linked to salt tolerance in simplified experimental systems whereas they have been rarely functionally proven in real agricultural contexts. In-depth analyses of specific crop-salinity interactions could reveal important aspects of plant salt stress adaptation as well as novel physiological/agronomic targets to improve salinity tolerance. These include the developmental role of root vs. shoot systems respect to water-ion homeostasis, morphological vs. metabolic contributions to stress adaptation, developmental processes vs. seasonal soil salinity evolution, residual effects of saline irrigation in non-irrigated crops, critical parameters of salt tolerance in soil-less systems and controlled environments, response to multiple stresses. Finally, beneficial effects of salinization on qualitative parameters such as stress-induced accumulation of high nutritional value secondary metabolites should be considered, also. In this short review we attempted to highlight the multifaceted nature of salinity in Mediterranean agricultural systems by summarizing most experimental activity carried out at the Department of Agricultural Engineering and Agronomy of University of Naples Federico II in the last few years.

  5. Agriculture: access to technology limited.

    Science.gov (United States)

    1997-01-01

    From country to country and even regionally, the roles of women in agriculture vary, but most of their labor is in unpaid subsistence production and their contributions tend to be underestimated, according to the results of the [UN] Secretary-General's report. Depending on circumstances, they have complementary roles with men, sharing or dividing tasks in the production of crops, care of animals, and forestry management. In sub-Saharan Africa, for example, women contribute 60-80% of labor in food production for both household consumption and sale, while in Malaysia the women account for only 35% of the agricultural labor force, and in Ireland the participation rate is only 10.4%. Although women make this important amount of labor contributions to agricultural production, "development policies tend to favor export crops to earn foreign exchange and the agricultural research tends to address the improvement of production and technologies for commercial production". This results in limited access for women to technical knowledge and innovations, including irrigation, machinery, farming techniques and extension services. This is strengthened by the fact that most of the extension services target farmers who own land and can obtain credit to invest in input and technology. full text

  2. Sustainable intensification in agricultural systems.

    Pretty, Jules; Bharucha, Zareen Pervez

    2014-12-01

    Agricultural systems are amended ecosystems with a variety of properties. Modern agroecosystems have tended towards high through-flow systems, with energy supplied by fossil fuels directed out of the system (either deliberately for harvests or accidentally through side effects). In the coming decades, resource constraints over water, soil, biodiversity and land will affect agricultural systems. Sustainable agroecosystems are those tending to have a positive impact on natural, social and human capital, while unsustainable systems feed back to deplete these assets, leaving fewer for the future. Sustainable intensification (SI) is defined as a process or system where agricultural yields are increased without adverse environmental impact and without the conversion of additional non-agricultural land. The concept does not articulate or privilege any particular vision or method of agricultural production. Rather, it emphasizes ends rather than means, and does not pre-determine technologies, species mix or particular design components. The combination of the terms 'sustainable' and 'intensification' is an attempt to indicate that desirable outcomes around both more food and improved environmental goods and services could be achieved by a variety of means. Nonetheless, it remains controversial to some. This review analyses recent evidence of the impacts of SI in both developing and industrialized countries, and demonstrates that both yield and natural capital dividends can occur. The review begins with analysis of the emergence of combined agricultural-environmental systems, the environmental and social outcomes of recent agricultural revolutions, and analyses the challenges for food production this century as populations grow and consumption patterns change. Emergent criticisms are highlighted, and the positive impacts of SI on food outputs and renewable capital assets detailed. It concludes with observations on policies and incentives necessary for the wider adoption of

    2013-03-01

    1. Introduction Better information on greenhouse gas (GHG) emissions and mitigation potential in the agricultural sector is necessary to manage these emissions and identify responses that are consistent with the food security and economic development priorities of countries. Critical activity data (what crops or livestock are managed in what way) are poor or lacking for many agricultural systems, especially in developing countries. In addition, the currently available methods for quantifying emissions and mitigation are often too expensive or complex or not sufficiently user friendly for widespread use. The purpose of this focus issue is to capture the state of the art in quantifying greenhouse gases from agricultural systems, with the goal of better understanding our current capabilities and near-term potential for improvement, with particular attention to quantification issues relevant to smallholders in developing countries. This work is timely in light of international discussions and negotiations around how agriculture should be included in efforts to reduce and adapt to climate change impacts, and considering that significant climate financing to developing countries in post-2012 agreements may be linked to their increased ability to identify and report GHG emissions (Murphy et al 2010, CCAFS 2011, FAO 2011). 2. Agriculture and climate change mitigation The main agricultural GHGs—methane and nitrous oxide—account for 10%-12% of anthropogenic emissions globally (Smith et al 2008), or around 50% and 60% of total anthropogenic methane and nitrous oxide emissions, respectively, in 2005. Net carbon dioxide fluxes between agricultural land and the atmosphere linked to food production are relatively small, although significant carbon emissions are associated with degradation of organic soils for plantations in tropical regions (Smith et al 2007, FAO 2012). Population growth and shifts in dietary patterns toward more meat and dairy consumption will lead to

    While studies on media representations of agricultural biotechnology mostly analyse media texts, this work is intended to fill a research gap with an analysis of journalistic interpretations of media representations. The purpose of this project was to determine how news media represent agricultural biotechnology and how journalists interpret their own representations. A content and critical discourse analysis of news texts published in the Slovenian media over two years and in-depth interviews with their authors were conducted. News texts results suggest that most of the news posts were "othering" biotechnology and biotechnologists: biotechnology as a science and individual scientists are represented as "they," who are socially irresponsible, ignorant, arrogant, and "our" enemies who produce unnatural processes and work for biotechnology companies, whose greed is destroying people, animals, and the environment. Most journalists consider these representations to be objective because they have published the biotechnologists' opinions, despite their own negative attitudes towards biotechnology.

    Akyuz, F.; Mullins, B.; Morlock, D.; Carcoana, R.

    2010-09-01

    The North Dakota Agricultural Weather Network (NDAWN) consists of 72 automated weather stations spread across agricultural locations of North Dakota, the Red River Valley, and border regions of surrounding states. The NDAWN Center is a part of the Department of Soil Science, North Dakota State University. The NDAWN stations measure wind speed and direction, air temperature, rainfall, solar radiation, pressure (31 stations), atmospheric moisture and soil temperatures under bare and turf at 10 cm (4 inch) depth. The center provides daily summaries consisting of maximums and minimums as well as time of occurrence, and various totals or averages for all variables in English or metric units. Measured and calculated variables along with complete descriptions are available. The NDAWN Center web site: http://ndawn.ndsu.nodak.edu/ allows direct access to NDAWN data in various special and temporal scales. The voice modem accommodates those who do not have internet access. The NDAWN Center has assisted many North Dakotans in making weather critical decisions concerning their crops, livestock, and livelihood. The stations provide weather data, which was instrumental in developing various agricultural models including but not limited to the late blight model, degree day and growth stage models for barley, corn, canola, potato, sugarbeet, sunflower, wheat and other small grains, irrigation scheduling, crop water use, sugarbeet root maggot, and insect development models. Late blight model, for example, predicts when leaf disease can occur in potato plants. Late blight doesn't occur in North Dakota every year and is prevalent during cool and moist periods of weather. In 1993-94, this model predicted that late blight would occur and growers were able to use fungicide applications to prevent the disease. Another direct benefit of NDAWN data is that it provides universities and the National Weather Service with an additional database for research and forecasting applications

    2017-04-01

    Soil water erosion is one of the major threats to soil resources throughout the world. Conventional agriculture has worsened the situation. Therefore, agriculture is facing multiple challenges: it has to produce more food to feed a growing population, and, on the other hand, safeguard natural resources adopting more sustainable production practices. In this perspective, more conservation-minded soil management practices should be taken to achieve an environmental sustainability of crop production. Indeed, conservation agriculture is considered to produce relevant environmental positive outcomes (e.g. reducing runoff and soil erosion, improving soil organic matter content and soil structure, and promoting biological activity). However, as mechanical weed control is limited or absent, in conservation agriculture, dependence on herbicides increases especially in the first years of transition from the conventional system. Consequently, also the risk of herbicide losses via runoff or adsorbed to eroded soil particles could be increased. To better analyse the complexity of soil water erosion and runoff processes in landscapes characterised by conservation agriculture, first, it is necessary to demonstrate if such different practices can significantly affect the surface morphology. Indeed, surface processes such erosion and runoff strongly depend on the shape of the surface. The questions are: are the lands treated with conservation and conventional agriculture different from each other regarding surface morphology? If so, can these differences provide a better understanding of hydrogeomorphic processes as the basis for a better and sustainable land management? To give an answer to these questions, we considered six study areas (three cultivated with no-tillage techniques, three with tillage techniques) in an experimental farm. High-resolution topography, derived from low-cost and fast photogrammetric techniques Structure-from-Motion (SfM), served as the basis to

    Full Text Available Problem statement: Jordans agricultural extension service is seriously under-staffed and its effectiveness is consequently compromised. Reservations are being expressed about the performance and capability of the agricultural extension system in Jordan. The performance of this sector has been disappointing and has failed to transfer agricultural technology to the farmers. The main objective of this study is to assess the effectiveness of Jordans agricultural extension services. Approach: The effect of extension services on olive productivity in the study area was investigated. A total number of 60 olive producers were selected to be interviewed for this study. This number was enough to achieve the study objectives. The interviewed producers were distributed almost equally within olive production locations in the study area. The sample obtained through the simple random sampling technique. The two groups had been chosen and distributed randomly into an experimental group (30 farmers; 10 for each source of extension service and control group (30 farmers. The experimental group received extension services and the control group received no extension services. Two interview-cum-structured questionnaires were designed and used to collect information and data for this study. The first instrument was designed for farmers who received extension services and the second from farmers who received no extension services. Another questionnaire was designed for administrators of extension organizations concerned with providing extension services to farmers. To find the differences that may exist between two studied groups, One Way Analysis of Variance (ANOVA, t-test and LSD test via Statistical Package for Social Sciences software (SPSS were used. The average net profit obtained from an area of one dynamo of olive farm was the main item to be considered in determining the effectiveness of agricultural extension activities.

    Fungicides are very important and diverse environmental and agricultural concern species. Their determination in commercial formulations or environmental matrices, requires highly efficient, selective and sensitive methods. A significant number of these chemicals are chiral with the activity residing usually in one of the enantiomers. The different toxicological and degradation behavior observed in many cases for fungicide enantiomers, results in the need to investigate them separately. For this purpose, separation techniques such as GC, HPLC, supercritical fluid chromatography (SFC) and CE have widely been employed although, at present, HPLC still dominates chromatographic chiral analysis of fungicides. This review covers the literature concerning the enantiomeric separation of fungicides usually employed in agriculture grouping the chiral separation methodologies developed for their analysis in environmental, biological, and food samples.

    Full Text Available Despite the rapid diffusion of transgenic crops, there are still few environmental impact studies capable of supplying a conclusive scientific response in regard to its technical and economic advantages and disadvantages. Prospective scenarios were elaborated to assist environmental impact assessment, using techniques derived from SWOT (Strength, Weakness, Opportunity, Threat analysis and the DPSIR (Driving Force – human activity, Pressure, State, Impact, Response model, to evaluate the environmental indicators and the relationship between them. Control and management actions were identified, searching the integration of aspects related to the biotechnology applied to transgenic processes, biodiversity, biosafety and intellectual property. It was demonstrated that the DPSIR model is, in fact, an instrument for integrated environmental assessment and the application of the proposed methodology resulted in favorable indicators to the adoption of transgenic agriculture. The elaborated scenarios are useful to develop an Environmental Management System (EMS to agriculture.

    It is a large task for Japan to positively promote the Joint Implementation activities related to the United Nations Framework Convention on Climate Change. Rapid increase in the emission of greenhouse-effect gases, especially CO2, is predicted in China with remarkable economic growth and population of 1.2 billion. It is essential to promote the Joint Implementation activities in China. In this survey, framework, organization, problems and tasks were investigated to effectively promote the Joint Implementation activities in China. Construction of framework for the real Joint Implementation activities has been proposed. Current problems for promoting the Joint Implementation activities in China are that the distinct guideline for the Joint Implementation is not established in the government, that the receiving system including receiving, planning and arranging sections is not established, and that the burden problems for the costs of project evaluation, data acquisition, monitoring, and verification are not solved. 5 refs., 21 figs., 6 tabs.

  3. Groundwater recharge and agricultural contamination

    Böhlke, J.K.

    2002-01-01

    Agriculture has had direct and indirect effects on the rates and compositions of groundwater recharge and aquifer biogeochemistry. Direct effects include dissolution and transport of excess quantities of fertilizers and associated materials and hydrologic alterations related to irrigation and drainage. Some indirect effects include changes in water-rock reactions in soils and aquifers caused by increased concentrations of dissolved oxidants, protons, and major ions. Agrilcultural activities have directly or indirectly affected the concentrations of a large number of inorganic chemicals in groundwater, for example NO3-, N2, Cl, SO42-, H+, P, C, K, Mg, Ca, Sr, Ba, Ra, and As, as well a wide variety of pesticides and other organic compounds. For reactive contaminants like NO3-, a combination of chemical, isotopic, and environmental-tracer analytical approaches might be required to resolve changing inputs from subsequent alterations as causes of concentration gradients in groundwater. Groundwater records derived from multi-component hydrostratigraphic data can be used to quantify recharge rates and residence times of water and dissolved contaminants, document past variations in recharging contaminant loads, and identify natural contaminant-remediation processes. These data indicate that many of the world's surficial aquifers contain transient records of changing agricultural contamination from the last half of the 20th century. The transient agricultural groundwater signal has important implications for long-term trends and spatial heterogeneity in discharge.

  4. Analyzing Agricultural Agglomeration in China

    2017-02-01

    Full Text Available There has been little scholarly research on Chinese agriculture’s geographic pattern of agglomeration and its evolutionary mechanisms, which are essential to sustainable development in China. By calculating the barycenter coordinates, the Gini coefficient, spatial autocorrelation and specialization indices for 11 crops during 1981–2012, we analyze the evolutionary pattern and mechanisms of agricultural agglomeration. We argue that the degree of spatial concentration of Chinese planting has been gradually increasing and that regional specialization and diversification have progressively been strengthened. Furthermore, Chinese crop production is moving from the eastern provinces to the central and western provinces. This is in contrast to Chinese manufacturing growth which has continued to be concentrated in the coastal and southeastern regions. In Northeast China, the Sanjiang and Songnen plains have become agricultural clustering regions, and the earlier domination of aquaculture and rice production in Southeast China has gradually decreased. In summary, this paper provides a political economy framework for understanding the regionalization of Chinese agriculture, focusing on the interaction among the objectives, decisionmaking behavior, path dependencies and spatial effects.

    Full Text Available Information and Communication Technologies (ICTs have contributed in one way or the other to many transformations in contemporary society. The contexts and the impacts of such transformations are particularly significant for developing societies like India. The relevance of new computing technologies and their effective implementation in developing countries is widely debated, both at policy and community level. Needless to say, FOSS (Free Open Source Software has encouraged the participation of civil society, creating potential for developing specific information technology tools. In this context, the OSCAR-project (Open Source Simple Computer for Agriculture in Rural Areas is an initiative from European and South Asian Institutions to assist decision making in agriculture. OSCAR developed a weed identification system for the major weed species in rice-wheat cropping systems of the Indo-Gangetic Plains (IGPs covering Pakistan, India, Nepal and Bangladesh. An integral part of the OSCAR-project is its applicability to three categories of potential users: farmers, extension officers, and, scientists and students in agricultural sciences. OSCAR was evaluated through extensive interactions with farmer groups, extension personnel, IT specialists, NGO and UN staff, government officials, scientific researchers and PhD students in various disciplines and MSc students from various programs in all the four IGP countries. The experience from OSCAR is helpful in understanding the larger contexts and the impact of ICT interventions in an interdisciplinary framework.

Several reports highlighted the need for better agricultural practices and use of eco-friendly methods for sustainable crop production under such situations. In this context, Trichoderma species could be a model fungus to sustain crop productivity. Currently, these are widely used as inoculants for biocontrol, biofertilization, and phytostimulation. They are reported to improve photosynthetic efficiency, enhance nutrient uptake and increase nitrogen use efficiency in crops. Moreover, they can be used to produce bio-energy, facilitate plants for adaptation and mitigate adverse effect of climate change. The technological advancement in high throughput DNA sequencing and biotechnology provided deep insight into the complex and diverse biotic interactions established in nature by Trichoderma spp. and efforts are being made to translate this knowledge to enhance crop growth, resistance to disease and tolerance to abiotic stresses under field conditions. The discovery of several traits and genes that are involved in the beneficial effects of Trichoderma spp. has resulted in better understanding of the performance of bioinoculants in the field, and will lead to more efficient use of these strains and possibly to their improvement by genetic modification. The present mini-review is an effort to elucidate the molecular basis of plant growth promotion and defence activation by Trichoderma spp. to garner broad perspectives regarding their functioning and applicability for climate resilient agriculture.

  1. The imperative for regenerative agriculture.

    Science.gov (United States)

    Rhodes, Christopher J

    2017-03-01

    A review is made of the current state of agriculture, emphasising issues of soil erosion and dependence on fossil fuels, in regard to achieving food security for a relentlessly enlarging global population. Soil has been described as "the fragile, living skin of the Earth", and yet both its aliveness and fragility have all too often been ignored in the expansion of agriculture across the face of the globe. Since it is a pivotal component in a global nexus of soil-water-air-energy, how we treat the soil can impact massively on climate change - with either beneficial or detrimental consequences, depending on whether the soil is preserved or degraded. Regenerative agriculture has at its core the intention to improve the health of soil or to restore highly degraded soil, which symbiotically enhances the quality of water, vegetation and land-productivity. By using methods of regenerative agriculture, it is possible not only to increase the amount of soil organic carbon (SOC) in existing soils, but to build new soil. This has the effect of drawing down carbon from the atmosphere, while simultaneously improving soil structure and soil health, soil fertility and crop yields, water retention and aquifer recharge - thus ameliorating both flooding and drought, and also the erosion of further soil, since runoff is reduced. Since food production on a more local scale is found to preserve the soil and its quality, urban food production should be seen as a significant potential contributor to regenerative agriculture in the future, so long as the methods employed are themselves 'regenerative'. If localisation is to become a dominant strategy for dealing with a vastly reduced use of fossil fuels, and preserving soil quality - with increased food production in towns and cities - it will be necessary to incorporate integrated ('systems') design approaches such as permaculture and the circular economy (which minimise and repurpose 'waste') within the existing urban infrastructure.

  15. The Basic Path of Modern Agriculture with Chinese Characteristics-Industry Nurturing Agriculture

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    Constructing the modern agriculture with Chinese characteristics is the path and direction for solving issues concerning agriculture, countryside and farmers in China, the key to new village construction, the important measure for promoting overall agricultural production capacity, and the prerequisite and guarantee for coordinating urban-rural development. At present, the level of agricultural mechanization in China is promoted steadily; the science and technology are applied to agriculture extensively; the agricultural regionalization layout gradually takes shape; the agricultural industrialization management develops steadily. Be that as it may, the overall quality of farmers is low; the agricultural infrastructure is weak; the agricultural resources are limited; the inputs of agricultural science and technology are short. These hamper the development of modern agriculture. We should implement "industry nurturing agriculture"; through capital support and policy guidance, reform household registration system; connect the fragmented land into parcel; encourage the leading enterprises to develop in rural areas; establish agricultural cooperative organizations; deepen rural financial system reform; quicken the promotion and application of agricultural technology. These measures can effectively promote the development of agriculture, and realize the agricultural modernization in China.

    Hot and cold mineral waters are used in two ways in agriculture: one for irrigation and other as a heat resource. Irrigation is widely applied in Turkey when the chemical composition of water is found suitable for the purpose. However as a heat resource it is almost never used. Studies showed that the hot waters of Turkey have 4665 billion kcal (equivalent of 450 thousand tons) which means green-houses can be established over an area about 4665 decar for growing vegetable and fruits. The approximate income of the green houses is estimated millions of Turkish lira.

Unlike the pessimistic view of Malthus and neo-maltusianists, who considered population and food resources a given disequilibrium, from the individual entrepreneurs and farmers up to the macroeconomic decedents of the rural policies, they all prove a continuous commitment to feed consumers with their basic requirements. This is why investments and subventions in agriculture have important particularities and consequences, and play a major role on the global market.

    The onset and course of puberty is under the control of the neuroendocrine system. Factors affecting the regulation of timing and order of this system's functions may alter the onset and course of puberty. Several environmental endocrine disruptors (EDs) with significant influences on the normal course of puberty have been identified. Despite the numerous animal and human studies on EDs that may extensively affect human health, there are still several issues that need to be clarified. This chapter discusses the effects of pesticides, which constitute a significant portion of disruptors and have been increasingly used in agriculture, on precocious puberty.

    2014-12-01

    Climate-smart agriculture (CSA) is an approach for transforming and reorienting agricultural systems to support food security under the new realities of climate change. Widespread changes in rainfall and temperature patterns threaten agricultural production and increase the vulnerability of people dependent on agriculture for their livelihoods, which includes most of the world's poor. Climate change disrupts food markets, posing population-wide risks to food supply. Threats can be reduced by increasing the adaptive capacity of farmers as well as increasing resilience and resource use efficiency in agricultural production systems. CSA promotes coordinated actions by farmers, researchers, private sector, civil society and policymakers towards climate-resilient pathways through four main action areas: (1) building evidence; (2) increasing local institutional effectiveness; (3) fostering coherence between climate and agricultural policies; and (4) linking climate and agricultural financing. CSA differs from 'business-as-usual' approaches by emphasizing the capacity to implement flexible, context-specific solutions, supported by innovative policy and financing actions.

    Full Text Available Because of the fact that specialty agricultural assistance is not always available when the farmers need it, we identified expert systems as a strong instrument with an extended potential in agriculture. This started to grow in scale recently, including all socially-economic activity fields, having the role of collecting data regarding different aspects from human experts with the purpose of assisting the user in the necessary steps for solving problems, at the performance level of the expert, making his acquired knowledge and experience available. We opted for a general presentation of the expert systems as well as their necessity, because, the solution to develop the agricultural system can come from artificial intelligence by implementing the expert systems in the field of agricultural insurance, promoting existing insurance products, farmers finding options in depending on their necessities and possibilities. The objective of this article consists of collecting data about different aspects about specific areas of interest of agricultural insurance, preparing the database, a conceptual presentation of a pilot version which will become constantly richer depending on the answers received from agricultural producers, with the clearest exposure of knowledgebase possible. We can justify picking this theme with the fact that even while agricultural insurance plays a very important role in agricultural development, the registered result got from them are modest, reason why solutions need to be found in the scope of developing the agricultural sector. The importance of this consists in the proposal of an immediate viable solution to correspond with the current necessities of agricultural producers and in the proposal of an innovative solution, namely the implementation of expert system in agricultural insurance as a way of promoting insurance products. Our research, even though it treats the subject at an conceptual level, it wants to undertake an

    Full Text Available In Front of new prospects and the environmental concerns with sustainable development, always more the science, communities, institutions of education and general managers have been engaged in developing new strategies and methodologies to work in urban and rural area. The aims are not harming the environment and optimize the processes of action, trying to maximize profits. The objective of this study was to verify the current state of knowledge of environmental education and dissemination of information on subsistence agriculture, within the national context. The methodology was based on a qualitative literature review, with exploratory character, exposing the main arguments used and their applicability. The results showed that although there are many options to work for environmental education in family agriculture, few things has been done in practice. It was verified that the main focus of environmental education in the field is restricted to activities with planting of seedlings for reforestation of degraded areas and conservation of riparian forests. Although, the environmental education may involve several techniques aimed at improving the quality of life in the field. Also, working only with "green marketing" themes are not that interesting, when we talk about sustainability.

    Full Text Available Much of the development and degradation of karst lands in Australia has occurred in the last two centuries since European settlement. Recent prolonged El Nino events add further climatic uncertainty and place real constraints on sustainable agriculture. The lower southeast of South Australia is perhaps the one area in Australia where karst, and particularly karst hydrology, impinge on the daily lives of the community in that pollution and overexploitation of the aquifer are readily apparent to the local population. Effluent from intensive dairy farms, piggeries and cheese factories enters the karst and has caused concern over pollution of water supplies. Human impacts on the Mole Creek karst of Tasmania have been well documented. The principal recent impacts on the karst arc associated with land clearance for farmland, forest cutting for timber, road building, refuse disposal and associated hydrological change. There is similar evidence of agricultural impacts un karst in central New South Wales, with clear evidence of vegetation clearance and soil stripping on the limestones at Wellington, Orange and Molong.

    From the point of view of agricultural civilization, the history of human civilization is the history of the development of the agricultural civilization. Accompanied by social progress and development of the times, the function of agriculture also experiences the expansion and deepening. In terms of economy, there is a process from mechanized farming to industrialization, then to informatization, modernization and internationalization. The great rejuvenation of the Chinese nation has also experienced and witnessed this process. In terms of "agriculture, countryside and farmers", the content is complex, diverse, profound, sharp, and changing, constantly testing and challenging our wisdom. When the Document No.1 in 2007 targeted modern agriculture, it indicated that new connotation was integrated into agricultural multifunctionality, standing at a new starting point. At present, the function of agriculture is still deepening; there are tremendous achievements and outstanding problems concurrently in issues concerning agriculture, countryside and farmers.

    Full Text Available Evaluating of oils condition in agricultural machinery is very important. With monitoring and evaluating we can prevent technical and economic losses. In this paper there were monitored the liquid lubricants taken from mobile thresher New Holland CX 860. Chemical and viscosity degradation of the lubricants were evaluated. Temperature dependence dynamic viscosity was observed in the range of temperature from −10 °C to 80 °C (for all oils. Considerable temperature dependence dynamic viscosity was found and demonstrated in case of all samples, which is in accordance with theoretical assumptions and literature data. Mathematical models were developed and tested. Temperature dependence dynamic viscosity was modeled using a polynomial 6th degree. The proposed models can be used for prediction of flow behavior of oils.

  17. Review – Cities and Agriculture

    Directory of Open Access Journals (Sweden)

    Aloysius Clemence Mosha

    2017-04-01

    Full Text Available As people increasingly migrate to urban settings and with more than half of the world’s population now living in cities, it is vital to plan and provide for sustainable and resilient food systems which reflect this challenge. The book ‘Cities and Agriculture’ presents experience and evidence on key dimensions of urban food challenges and types of intra-and peri-urban agriculture, in 15 extremely well-researched and written chapters. The book has shed light on an urban challenge that has been ignored for a long time in urban studies as well as in urban policies and planning, i.e. food-provisioning. Neglecting the dynamics and sustainability of food provisioning in scientific research on sustainable urban development is a serious omission, because feeding cities arguably has a greater social and physical impact on us and our planet than anything else we do.

    1981-09-01

    A dry fermentation process is discussed which converts agricultural residues to methane, using the residues in their as produced state. The process appears to simplify and enhance the possibilities for using crop residues as an energy source. The major process variables investigated include temperature, the amount and type of inoculum, buffer requirements, compaction, and pretreatment to control the initial available organic components that create pH problems. A pilot-scale reactor operation on corn stover at a temperature of 550 C, with 25 percent initial total solids, a seed-to-feed ratio of 2.5 percent, and a buffer-to-feed ratio of 8 percent achieved 33 percent total volatile solids destruction in 60 days. Volumetric biogas yields from this unit were greater than 1 vol/vol day for 12 days, and greater than 0.5 vol/vol day for 32 days, at a substrate density of 169 kg/m (3).

    Full Text Available The purpose of this paper is to introduce a modification of a standardfour input production process where energy is used in an inefficient way due topartly unnecessary waste of energy. The changes in production efficiencyinvestigated using stochastic frontier methods, show declining technicalefficiency in livestock production and especially low marginal contribution oflabor inputs. The number of workers, size of farm, and distance from nearestcity are related to efficiency in agricultural production. It is well known thatresults from an environmental policy in response to global climate change arequite sensitive to the assumption on the rate of energy efficiency improvements.However, technical progress is traditionally considered as a non-economicvariable in economic policy models. It is exogenous in most policy evaluationsas well as in the theory of environmental economics.

  20. Migrant labor in agriculture: an international comparison.

    Science.gov (United States)

    Martin, P L

    1985-01-01

    The May 1984 Conference on Migrant Labor in Agriculture at the University of California-Davis discussed papers by 22 farm labor experts from 12 nations. Each industrial nation utilizes a different set of public and private policies to supply workers for labor-intensive agriculture, but none is entirely satisfactory. Labor-intensive agriculture is becoming more dependent on workers who are shut out of labor markets. Some countries have simply accepted foreign workers in agriculture, while others have adopted policies to integrate farm and nonfarm labor markets. Polices to reduce agriculture's reliance on workers-without-options include restructuring employment practices to employ fewer seasonal workers for longer periods, mechanizing production, and importing fruits and vegetables from nearby developing countries. This article explains the salient features of labor-intensive agriculture, the various polices for obtaining seasonal farmworkers, and options to reduce farming's dependence on migrant labor.

  1. Crop Insurance, Premium Subsidy and Agricultural Output

    Institute of Scientific and Technical Information of China (English)

    XU Jing-feng; LIAO Pu

    2014-01-01

    This paper studied the effects of crop insurance on agricultural output with an economic growth model. Based on Ramsey-Cass-Koopmans (RCK) model, a basic model of agriculture economic growth was developed. Extending the basic model to incorporate uncertainty and insurance mechanism, a risk model and a risk-insurance model were built to study the inlfuences of risk and crop insurance on agricultural output. Compared with the steady states of the three models, the following results are achieved:(i) agricultural output decreases if we introduce uncertainty into the risk-free model;(ii) crop insurance promotes agriculture economic growth if insurance mechanism is introduced into the risk model;(iii) premium subsidy constantly improves agricultural output. Our contribution is that we studied the effects of crop insurance and premium subsidy from the perspective of economic growth in a dynamic framework, and proved the output promotion of crop insurance theoretically.

    2017-06-01

    Re-structuring the practices of traditional inventory management is becoming more essential to optimize the supply chain transparency and accuracy of agricultural produce. A flexible and transparent inventory management system is becoming the need of any agricultural commodity. It was noticed that the major setback for the farmers who are the suppliers of the farm produce is due to poor supply chain integration. The recent advent technologies and IT explosion can bring up a greater impact in the process of storing, tracking, distributing and monitoring perishable agriculture produce of day to day life. The primary focus of this paper is to integrate IoT into inventory management and other inbound logistics management of agriculture produce. The unique features of agricultural produce like a prediction of supply, demand, the location of warehouses, distribution and tracking of inventory can be integrated through IoT. This paper proposes a conceptual framework for inventory management transparency involved in the supply chain of agriculture produce.

    Agricultural productivity is expected to be sensitive to global climate change. Models from atmospheric science, plant science, and agricultural economics are linked to explore this sensitivity. Although the results depend on the severity of climate change and the compensating effects of carbon dioxide on crop yields, the simulation suggests that irrigated acreage will expand and regional patterns of U.S. agriculture will shift. The impact of the U.S. economy strongly depends on which climate model is used.

    2014-08-01

    Full Text Available The term ecological agriculture has been attributed by the European Union of Romania to define this system of agriculture and is similar with terms organic agriculture or biological agriculture, which are used in other member states. One of the main goals of ecological agriculture is the production of agricultural and food products fresh and genuine through processes created to respect nature and its systems. Thus, it prohibits the use of genetically modified organisms, fertilizers and synthetic pesticides, stimulators and growth regulators, hormones, antibiotics for livestock and the use of synthetic chemical fertilizers, drastic interventions on the soil, the introduction of genetically modified organisms, in the case of the cultivated soil. The study aims to highlight the main features of ecological agriculture and its impact on the national economy. Through a descriptive and comparative analysis of specific indicators are surprising the main aspects of ecological agriculture performance in Romania and are identified investment opportunities in this sector of the national economy. Following this study, it was found that ecological agriculture in Romania is quite performant and recorded a continuous development, but mainly in the production, not in the processing and trading of natural products, which is why investment in these areas would be welcome.

  19. The costly benefits of opposing agricultural biotechnology.

    Science.gov (United States)

    Apel, Andrew

    2010-11-30

    Rigorous application of a simple definition of what constitutes opposition to agricultural biotechnology readily encompasses a wide array of key players in national and international systems of food production, distribution and governance. Even though the sum of political and financial benefits of opposing agricultural biotechnology appears vastly to outweigh the benefits which accrue to providers of agricultural biotechnology, technology providers actually benefit from this opposition. If these barriers to biotechnology were removed, subsistence farmers still would not represent a lucrative market for improved seed. The sum of all interests involved ensures that subsistence farmers are systematically denied access to agricultural biotechnology. Copyright © 2010 Elsevier B.V. All rights reserved.

  7. Towards Conservation Agriculture systems in Moldova

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available As the world population and food production demands rise, keeping agricultural soils and landscapes healthy and productive are of paramount importance to sustaining local and global food security and the flow of ecosystem services to society. The global population, expected to reach 9.7 billion people by 2050, will put additional pressure on the available land area and resources for agricultural production. Sustainable production intensification for food security is a major challenge to both industrialized and developing countries. The paper focuses on the results from long-term multi-factorial experiments involving tillage practices, crop rotations and fertilization to study the interactions amongst the treatments in the context of sustainable production intensification. The paper discusses the results in relation to reported performance of crops and soil quality in Conservation Agriculture systems that are based on no or minimum soil disturbance (no-till seeding and weeding, maintenance of soil mulch cover with crop biomass and cover crops, and diversified cropping s involving annuals and perennials. Conservation Agriculture also emphasizes the necessity of an agro-ecosystems approach to the management of agricultural land for sustainable production intensification, as well as to the site-specificity of agricultural production. Arguments in favor of avoiding the use of soil tillage are discussed together with agro-ecological principles for sustainable intensification of agriculture. More interdisciplinary systems research is required to support the transformation of agriculture from the conventional tillage agriculture to a more sustainable agriculture based on the principles and practices of Conservation Agriculture, along with other complementary practices of integrated crop, nutrient, water, pest, energy and farm power management.

  8. ANALYSIS OF DIVERSIFICATION EFFORTS IN AGRICULTURAL EDUCATION

    Directory of Open Access Journals (Sweden)

    PROCHÁZKA, Petr

    2011-09-01

    Full Text Available Study of agriculture enjoys less popularity over time in most of the developed countries, including Canada and the Czech Republic. Analysis in this paper provides interesting findings about activities of agricultural universities to increase enrollment into their programs. While the study is focused on Canada, it is possible to draw implications also for the Czech Republic as many of the characteristics pertaining to the education and agricultural sectors are similar. Enrollment into educational programs in agriculture in North America has been steadily declining in the last several decades. While the overall share of agriculture on national gross domestic product has also been falling, the need for qualified people in agriculture is still eminent as the shift to sustainable agriculture appears to be one of the key priorities of governments in the US and Canada. One of the ways how to facilitate interest of prospective students to study agriculture is to diversify the programs through offering of more major options. It is important to study the motivation and other stimuli for the choice of major in order to adapt the educational programs and attract more students. In the paper, factors influencing the choice of major are studied by analyzing survey data from the only agricultural college in Atlantic Canada. The results show significant differences in the socio-economic background among the prospective students based on the choice of major. For example, students interested in social sciences much more appraise more choices of major than students in biophysical fields. Based on the findings from the analysis, several recommendations are made. It is suggested, for example, that for students interested in biophysical sciences, sport plays an important role and thus, appropriate promotional campaign about recreation and sport facilities of a post-secondary agricultural educational institutions should be conducted. Analysis in this paper may serve

    2015-06-01

    Full Text Available The idea of a sustainable agriculture has gained prominence since the publication of the Brundtland Report in 1987. Yet, the concept of sustainable agriculture is very vague and ambiguous in its meaning, which renders its use and implementation extremely difficult. In this systematic review paper, we aim to advance understandings of sustainable agriculture from a social science and governance perspective by identifying areas of complementarity and concern between emerging definitions of sustainable agriculture. For this purpose, we conducted a structured literature review in combination with a cluster analysis in order to (1 identify the overall ideas and aspects associated with sustainable agriculture; (2 detect patterns and differences in how these ideas and aspects are adopted or applied; (3 evaluate how the different ideas and aspects of sustainable agriculture are combined in the scientific debate, and assess whether these different conceptions match with those that have been claimed to exist in the debate. There are two valuable outcomes from this research. The first is a framework for understanding the components of sustainable agriculture. The second outcome is in highlighting ways for actors involved with sustainable agriculture to deal with the complexity and multiplicity of this concept in a constructive manner.

    Agriculture is facing great challenge in meeting global food security and is expected to face even greater challenge under climate change. The overall goal of this paper is to examine how ifnance can be used to achieve the joint objectives of development, mitigation of and adaptation to climate change in agriculture in developing world based on literature review. The results show that agriculture is much under invested and foreign aid also has not increased appropriately to assist developing countries to maintain sustainable agriculture under climate change. There are a wide range of areas in mitigation of and adaptation to climate change that need substantial investment. Major areas and successful cases mitigation of and adaptation to climate change in agriculture that have worked in developing countries are examined. A list of areas that have worked, could work and be scaled up or transferred is identiifed and discussed. This study concludes that mainstreaming agricultural mitigation and adaptation into agricultural development programs, enhancing local capacity, and considering different stakeholders’ needs are major experiences for successfully ifnancing sustainable agriculture under climate change.

  14. Agriculture and growth nexus in Gambia

    Directory of Open Access Journals (Sweden)

    Bukhari Sillah

    2013-12-01

    Full Text Available Agriculture is a major engine for the economic well-being of the Gambia. The successive governments from the colonial periods to the present have all recognized this importance of the agricultural sector but failed to do something that bear any fruit since government encouraged slash and burn technology and putting increasingly more people onto the land instead of increasing the yields per acre. More people than before do remain still on the land, but they are now poorer than their forefathers. Using autoregressive and vector error correction techniques to examine the growth-agriculture relation in the Gambia for the period from 1966 to 2009, it is found that the capital per worker is a significant and relevant factor input for the economic growth. The agricultural labor per acre is found to be irrelevant in both the short run and the long run analyses. The agricultural productivity measured as crop yields per acre is the most important variable for the economic growth in the Gambia. It boosts both the economic growth and the capital formation in the country. The agricultural policies should be focused on increasing the crop yields per acre not having more people back to the land. The processing, services and small manufacturing sectors should be developed and built into the agricultural policies in order to create redeployments for the agricultural labor surpluses.

    Full Text Available The main goal of the paper is to map the performance of Romanian farms from the perspective of livestock agricultural operations using principal component analysis technique (PCA and similarities between Romania and other countries from UE. The empirical results reveal that animal breedings farms are grouped into two categories :small and middle sized farms ; and the fact that Romania , one of Europe’s major forces in the field of livestock husbandry, has come to be one of the biggest importers of food products, although, by tradition, it is one of the continent’s countries with ideal conditions for breeding all species of animals. When clustering the countries we observ that in countries such as Greece, Italy, Portugal, Spain, cow farms, for example, do not exceed 10-16 heads and in Holland, England, Denmark, Belgium and France, the average farm size reaches 30-70 heads of milk cows. The cluster analysis revealed that in livestock operations, animal stock is the one that generates production, while the animal number indicates the size of the livestock unit.

  16. Meeting the Challenges for Agriculture

    Directory of Open Access Journals (Sweden)

    Les Copeland

    2011-06-01

    Full Text Available Ensuring food security is an ongoing global challenge. Many forecasts point to a need to increase food production by at least 70% if we are to feed the world’s projected population of nine billion in 2050. Recent volatility in commodity prices and the general upward trend in the cost of food are indicators that global food systems are now driven by demand rather than supply. There are various reasons for this: greater demand for animal protein with economic growth in developing countries; the continuing increase in world population; competition between food and bioenergy crops for land and water; low inventories of world grain stocks; reduced investment in agricultural R&D; and unfavorable weather resulting in a succession of poor harvests around the world. Increasing production of grains, which are the foundation of the human food supply, will have to be achieved through higher crop yields without boosting inputs of land, water and energy. Meeting community expectations for environmental stewardship and sustainability, and adapting food production to increasingly variable climate, add greatly to the challenge.

    Full Text Available Propolis has been ground in various areas of science, but its application in agriculture, is a recent and almost unknown subject. In agronomy work mainly seek to explore the antibiotic and antifungal properties of propolis, but other uses have been proposed, such as plant nutrition, pest control (such as mites and even reducing water stress in plants. Despite numerous utilities proven and proposals, there are many questions, particularly for the preparation of the extract, most appropriate chemical composition for a particular use, application forms, crude propolis extract in percentages, dose minimum efficiency, efficiency, etc. Given the above, the purpose of this literature review is to present the origin and chemical composition of propolis, making methodology of propolis extract, more effective dose in the control of fungi, plant pathogenic bacteria and reduce water stress. During the study, it can be seen that the difference in propolis composition occurs mainly due to the variability of vegetable composition in the vicinity of the hive, the bees forage and chemical composition is quite complex and variable in terms of both concentration and chemicals gifts. In the extraction, there are still many gaps to be studied, including the best way to obtain the extract, with questions about the best puller, with lack of consensus in the literature. On the efficiency of this technology, there are numerous studies with promising results, which allow implementation of technology in the field and these jobs concentrated in coffee crops, beans, cucumber and tomato.

    2017-07-01

    Agricultural systems science generates knowledge that allows researchers to consider complex problems or take informed agricultural decisions. The rich history of this science exemplifies the diversity of systems and scales over which they operate and have been studied. Modeling, an essential tool in agricultural systems science, has been accomplished by scientists from a wide range of disciplines, who have contributed concepts and tools over more than six decades. As agricultural scientists now consider the "next generation" models, data, and knowledge products needed to meet the increasingly complex systems problems faced by society, it is important to take stock of this history and its lessons to ensure that we avoid re-invention and strive to consider all dimensions of associated challenges. To this end, we summarize here the history of agricultural systems modeling and identify lessons learned that can help guide the design and development of next generation of agricultural system tools and methods. A number of past events combined with overall technological progress in other fields have strongly contributed to the evolution of agricultural system modeling, including development of process-based bio-physical models of crops and livestock, statistical models based on historical observations, and economic optimization and simulation models at household and regional to global scales. Characteristics of agricultural systems models have varied widely depending on the systems involved, their scales, and the wide range of purposes that motivated their development and use by researchers in different disciplines. Recent trends in broader collaboration across institutions, across disciplines, and between the public and private sectors suggest that the stage is set for the major advances in agricultural systems science that are needed for the next generation of models, databases, knowledge products and decision support systems. The lessons from history should be

    Full Text Available The paper focuses on the situation of the agricultural land market in Slovakia and in selected region of the SR – Nitra region, on the application and development of agricultural land prices in Slovakia and on the factors that influence the decisions of agricultural enterprises on the market with agricultural land. In this paper were used primary data obtained with interview method realized within the research of Department of European policies, Slovak University of Agriculture during the period 2012 – 2013 in all districts of region Nitra. The evaluation of the impact of agricultural subject on agricultural land market in Slovakia was realized by using the method of regression analysis. Based on the results from the research we can state that entrepreneurs still prefer more to rent land then to purchase a land. The main factors influencing the decision-making process of agricultural subjects are ownership fragmentation, the fragmentation of agricultural plots and business's financial situation and profitability of the purchase. Many entrepreneurs pointed to this indicator as one of the most influential in terms of increasing the market price, respectively as a reason for not signing the lease agreement. The agricultural land market in Slovakia is emerging but still not sufficiently transparent. Further development of the market will continue to be marked by the overall economic situation in agriculture, relatively low competitiveness of Slovak farmers in the European market and reduced profitability. Research showed that the most pronounced effect on the price of agricultural land and the amount of rent for agricultural land has the number of enterprises. Growing number of farms will increase the price or amount of rent for agricultural land.

  8. Sustainable agriculture: a challenge in Bangladesh

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available The sustainability of conventional agriculture in Bangladesh is under threat from the continuous degradation of land and water resources, and from declining yields due to indiscriminate use of agro-chemicals. Government is pursuing efforts to promote sustainable agriculture with emphasis on better use of on-farm resources and the reduction of external inputs. This paper presents four dimensions of agricultural sustainability as productivity, environmental stability, economical profitability, and social and economic equity. Six characters were selected to evaluate sustainability. Significant differences were found between the two systems (conventional and sustainable agriculture in crop diversification, soil fertility management, pests and diseases management, use of agro-chemicals and environmental issues. However, no significant variations were found in other indicators such as land-use pattern, crop yield and stability, risk and uncertainties, and food security. Although crop yield and financial return were found to be slightly higher in the conventional system, the economic return and value addition per unit of land did not show any difference. It can be suggested that sustainable agriculture has a tendency towards becoming environmental, economically and socially more sound than conventional agriculture, as it requires considerably less agro-chemicals, adds more organic matter to the soil, provides balanced food, and requires higher local inputs without markedly compromising output and financial benefits. Broad-policy measures, including the creation of mass awareness of adverse health effects of agrochemical-based products, are outlined for the promotion of sustainable agriculture.

    Globally, irrigated agriculture is both essential for food production and the largest user of water. A major challenge for hydrologic and agricultural research communities is assessing the sustainability of irrigated croplands under climate variability and change. Simulations of irrigated croplands generally lack key interactions between water supply, water distribution, and agricultural water demand. In this article, we explore the critical interface between water resources and agriculture by motivating, developing, and illustrating the application of an integrated modeling framework to advance simulations of irrigated croplands. We motivate the framework by examining historical dynamics of irrigation water withdrawals in the United States and quantitatively reviewing previous modeling studies of irrigated croplands with a focus on representations of water supply, agricultural water demand, and impacts on crop yields when water demand exceeds water supply. We then describe the integrated modeling framework for simulating irrigated croplands, which links trends and scenarios with water supply, water allocation, and agricultural water demand. Finally, we provide examples of efforts that leverage the framework to improve simulations of irrigated croplands as well as identify opportunities for interventions that increase agricultural productivity, resiliency, and sustainability.

  10. Exploring Agricultural Drainage's Influence on Wetland and ...

    Science.gov (United States)

    Artificial agricultural drainage (i.e. surface ditches or subsurface tile) is an important agricultural management tool. Artificial drainage allows for timely fieldwork and adequate root aeration, resulting in greater crop yields for farmers. This practice is widespread throughout many regions of the United States and the network of artificial drainage is especially extensive in flat, poorly-drained regions like the glaciated Midwest. While beneficial for crop yields, agricultural drains often empty into streams within the natural drainage system. The increased network connectivity may lead to greater contributing area for watersheds, altered hydrology and increased conveyance of pollutants into natural water bodies. While studies and models at broader scales have implicated artificial drainage as an important driver of hydrological shifts and eutrophication, the actual spatial extent of artificial drainage is poorly known. Consequently, metrics of wetland and watershed connectivity within agricultural regions often fail to explicitly include artificial drainage. We use recent agricultural census data, soil drainage data, and land cover data to create estimates of potential agricultural drainage across the United States. We estimate that agricultural drainage in the US is greater than 31 million hectares and is concentrated in the upper Midwest Corn Belt, covering greater than 50% of available land for 114 counties. Estimated drainage values for numerous countie

  11. The "Two Leaps" and Chinese Agricultural Modernization

    Institute of Scientific and Technical Information of China (English)

    The "Two Leaps" put forward by Deng xiao-ping on agriculture are expounded in the paper. The first leap is from the people’s commune to family land contract operation system. The weaknesses of people’s commune and innovation of family land contract operation system are analyzed. It is pointed out that the family contact operation system is the expansion and development of collective economy. The second leap is to develop appropriate scale operation and collective economy. The shortages of family contract system are analyzed. It is put forward that realizing scale operation of agriculture is the necessary demand for production development and collective economy road is the inevitable way for realizing Chinese agricultural appropriate scale operation. "Two leaps" gives clears way of agricultural modernization:consolidating the thoughts of starting from the reality, insisting the guidance of the fundamental position of agriculture and further promoting agricultural development; persistently stabilizing and perfecting rural basic operation system and timely promote rural system innovation; stimulating the thought that science and technology is the prior productiveness and developing agricultural modernization in a better and faster way.

    This guidebook presents a selection of technologies for climate change adaptation in the agriculture sector. A set of 22 adaptation technologies are showcased. These are based primarily on the principles of agroecology, but also include scientific technologies of climate and biological sciences complemented by important sociological and institutional capacity building processes that are required for climate change to function. The technologies cover: 1) Planning for climate change and variability. 2) Sustainable water use and management. 3) Soil management. 4) Sustainable crop management. 5) Sustainable livestock management. 6) Sustainable farming systems. 7) Capacity building and stakeholder organisation. Technologies that tend to homogenise the natural environment and agricultural production have low possibilities of success in environmental stress conditions that are likely to result from climate change. On the other hand, technologies that allow for, and promote diversity are more likely to provide a strategy which strengthens agricultural production in the face of uncertain future climate change scenarios. The 22 technologies showcased in this guidebook have been selected because they facilitate the conservation and restoration of diversity while also providing opportunities for increasing agricultural productivity. Many of these technologies are not new to agricultural production practices, but they are implemented based on the assessment of current and possible future impacts of climate change in a particular location. agroecology is an approach that encompasses concepts of sustainable production and biodiversity promotion and therefore provides a useful framework for identifying and selecting appropriate adaptation technologies for the agriculture sector. The guidebook provides a systematic analysis of the most relevant information available on climate change adaptation technologies in the agriculture sector. It has been compiled based on a literature

  13. Agricultural sustainability: concepts, principles and evidence.

    Science.gov (United States)

    Pretty, Jules

    2008-02-12

    Concerns about sustainability in agricultural systems centre on the need to develop technologies and practices that do not have adverse effects on environmental goods and services, are accessible to and effective for farmers, and lead to improvements in food productivity. Despite great progress in agricultural productivity in the past half-century, with crop and livestock productivity strongly driven by increased use of fertilizers, irrigation water, agricultural machinery, pesticides and land, it would be over-optimistic to assume that these relationships will remain linear in the future. New approaches are needed that will integrate biological and ecological processes into food production, minimize the use of those non-renewable inputs that cause harm to the environment or to the health of farmers and consumers, make productive use of the knowledge and skills of farmers, so substituting human capital for costly external inputs, and make productive use of people's collective capacities to work together to solve common agricultural and natural resource problems, such as for pest, watershed, irrigation, forest and credit management. These principles help to build important capital assets for agricultural systems: natural; social; human; physical; and financial capital. Improving natural capital is a central aim, and dividends can come from making the best use of the genotypes of crops and animals and the ecological conditions under which they are grown or raised. Agricultural sustainability suggests a focus on both genotype improvements through the full range of modern biological approaches and improved understanding of the benefits of ecological and agronomic management, manipulation and redesign. The ecological management of agroecosystems that addresses energy flows, nutrient cycling, population-regulating mechanisms and system resilience can lead to the redesign of agriculture at a landscape scale. Sustainable agriculture outcomes can be positive for food

    Since 2003, economic growth in Nigeria has been strong. Annual GDP grew by 9.1 percent per annum between 2003 and 2005 and by 6 .1 percent per annum between 2006 and 2008. Much of this growth can be attributed to the non-oil economy which has grown rapidly. This is due primarily to agriculture, which contributes approximately 35 percent to total GDP and supports 70 percent of the population. Agricultural research has been shown to be crucial in increasing agricultural productivity and reducin...

    There are many opportunities to leverage agricultural resources on existing lands without interfering with production of food, feed, fiber, or forest products. In the recently developed advanced biomass feedstock commercialization vision, estimates of potentially available biomass supply from agriculture are built upon the U.S. Department of Agriculture’s (USDA’s) Long-Term Forecast, ensuring that existing product demands are met before biomass crops are planted. Dedicated biomass energy crops and agricultural crop residues are abundant, diverse, and widely distributed across the United States. These potential biomass supplies can play an important role in a national biofuels commercialization strategy.

  19. A threshold area ratio of organic to conventional agriculture causes recurrent pathogen outbreaks in organic agriculture.

    Adl, S; Iron, D; Kolokolnikov, T

    2011-05-01

    Conventional agriculture uses herbicides, pesticides, and chemical fertilizers that have the potential to pollute the surrounding land, air and water. Organic agriculture tries to avoid using these and promotes an environmentally friendly approach to agriculture. Instead of relying on herbicides, pesticides and chemical fertilizers, organic agriculture promotes a whole system approach to managing weeds, pests and nutrients, while regulating permitted amendments. In this paper, we consider the effect of increasing the total area of agricultural land under organic practices, against a background of conventional agriculture. We hypothesized that at a regional scale, organic agriculture plots benefit from existing in a background of conventional agriculture, that maintains low levels of pathogens through pesticide applications. We model pathogen dispersal with a diffusive logistic equation in which the growth/death rate is spatially heterogeneous. We find that if the ratio of the organic plots to conventional plots remains below a certain threshold l(c), the pest population is kept small. Above this threshold, the pest population in the organic plots grows rapidly. In this case, the area in organic agriculture will act as a source of pest to the surrounding region, and will always infect organic plots as they become more closely spaced. Repeated localized epidemics of pest outbreaks threaten global food security by reducing crop yields and increasing price volatility. We recommend that regional estimates of this threshold are necessary to manage the growth of organic agriculture region by region. Copyright © 2011 Elsevier B.V. All rights reserved.

    Full Text Available The agriculture industry is part of an interconnected world that is continually navigating complex trade regulations and cultural barriers. Graduates of School-Based Agricultural Education programs need to be prepared to positively communicate with people from all over the world and to have an understanding of international agricultural practices. The purpose of this study was to explore the perceptions of Tennessee School-Based Agricultural Educators towards globalizing the secondary agricultural curriculum. Twenty-six School-Based Agricultural Educators were interviewed for this study. The interviewees represented the entire state of Tennessee, including both urban and rural programs. The use of thematic analysis allowed the following five themes to emerge: (a heightened awareness of living in a globalized world, (b vision for a globalized School-Based Agricultural Education program, (c benefits of exposure to a globalized School-Based Agricultural Education program, (d preparedness to teach from a globalized perspective, and (e professional development needs. Participants recognized the importance of teaching through a globalized agricultural curriculum and the benefits students received from experiencing a globalized agricultural curriculum. However, not every participant felt prepared to teach using a globalized curriculum and suggestions for professional development were made.

    2013-01-01

    With advance of urbanization and industrialization, modern agricultural development in Chinas economic developed areas (CEDAs) is greatly restricted by traditional concept. To speed up the development of modern agriculture in CEDAs, this paper takes Suzhou City as an example from theories supporting modern agricultural development. It demonstrates agriculture in CEDAs plays an important role in adjusting supply of agricultural and sideline products, reserving rural labor employment, protecting ecological environment, increasing farmers income, and passing on agricultural culture. It contends that CEDAs should take reserving basic farmland as prerequisite; take adequate supply of primary agricultural products, protection of living environment, maintenance of agricultural landscape, and inheritance of farming culture as objectives; establish perfect modern agricultural system through firmly setting up modern agricultural value concept; increase local public finance input; increase agricultural functional value from technical and management levels, to realize increase of farmers income, promote sustainable development of agriculture, promote integrated urban and rural development, as well as harmonious development of human and nature.

    Considering agricultural landscapes as networks can provide information about spatial connectivity relevant for a wide range of applications including pollination, pest management, and ecology. Global agricultural networks are well-described by power law rank-size distributions. However, regional analyses capture only a subset of the total global network. Most analyses are regional. In this paper, we seek to address the following questions: Does the globally observed scale-free property of agricultural networks hold over smaller spatial domains? Can similar properties be observed at kilometer to meter scales? We analyze 9 intensively cultivated Landsat scenes on 5 continents with a wide range of vegetation distributions. We find that networks of vegetation fraction within the domain of each of these Landsat scenes exhibit substantial variability - but still possess similar scaling properties to the global distribution of agriculture. We also find similar results using a 39 km2 IKONOS image. To illustrate an a...

The Common Agriculture Policy is focused on decoupling, modulation and cross-compliance. The single payment scheme will assure aids only for farms where production complies with environment, food safety, animal and plant health, animal welfare, and agricultural land maintenance in good condition. The new legislation provides the introduction of "green payments" related to the adoption of agricultural practices beneficial for the climate and the environment. The demographic growth imposes more production and a better distribution of food in the world. The EU has to be prepared to produce more because of the mass emigration to the rich countries from the region where food demand can not be covered.

    In China, urbanization of agricultural land around city agglomerations increases rapidly. Rapid urbanization of agricultural land affects food supply, land value and ecological balance in the society. In China, the urban builtup area had increased by 40% from 1996 to 2003. This increase came predominantly from farmland surrounding the cities. How the ongoing urbanization of China affects its agricultural land is the focus of this paper. In current studies, we have found that population density; urbanization degree and personal income are key factors that influence the urbanization process. Based on this, relation model has been established and to predict the general trends of the urban area expansion in China in 2020. In 2020, the constructed urban area of China would be increased by 1.3 times compared with 2003. In 2020, this study anticipates the conversion of about 32, 562 sq. km. agricultural land of China for urban use.

    The importance and role of the geosciences in studies of sustainable agriculture include such traditional research areas as, agromineral resource assessments, the mapping and classification of soils and soil amendments, and the evaluation of landscapes for their vulnerability to physical and chemical degradation. Less traditional areas of study, that are increasing in societal importance because of environmental concerns and research into sustainable systems in general, include regional geochemical studies of plant and animal trace element deficiencies and toxicities, broad-scale water quality investigations, agricultural chemicals and the hydrogeologic interface, and minimally processed and ion-exchange agrominerals. We discuss the importance and future of phosphate in the US and world based on human population growth, projected agromineral demands in general, and the unavailability of new, high-quality agricultural lands. We also present examples of studies that relate geochemistry and the hydrogeologic characteristics of a region to the bioavailability and cycling of trace elements important to sustainable agricultural systems. ?? 1993.

    Identifying vulnerable agricultural production areas is essential for any sustainable development/farming plan. Climate is among the most important factors that determine the agricultural potential of a region and the suitability of an area for a specific crop or land management, followed by soil characteristics and geomorphology. Temperature and rainfall in terms of quantity and spatiotemporal variability are the two climatic variables that determine the agricultural potential of an area and the risk involved in any new agronomical use. Also, extreme weather events, such as droughts, have to be taken into account. In this paper, two satellite derived indices are combined in GIS environment with soil maps and a Digital Elevation Model (DEM) in order to identify the agricultural potential of areas. Namely, these indices are the Vegetation Health Index (VHI) and the Degree Days (DD) (also known as Heat Units). VHI represents overall vegetation health and is used for agricultural drought monitoring and mapping. DD units (oC d) are often used in agriculture in order to estimate or predict the lengths of the different phases of the development in crop plants, since temperature has a primary role in the growth of many organisms (plants and insects). The two indices are computed for 20 hydrological years, from October 1981 to September 2001, from NOAA/AVHRR ten -day composite images with 8x8 Km spatial resolution. DD is examined for crops of great commercial importance. The soil maps are digitized according to fertility (appropriate or not for agricultural use) and desertification vulnerability, whereas altitude based limitations are provided by the DEM. The study area is the water district of Thessaly, the largest lowland formation of Greece and the country's largest agricultural centre, located in Central Greece. The superposition of the two indices along with the soil and elevation data had led to the identification of vulnerable agricultural production areas. The

  14. Sustainable agricultural water management across climates

    DeVincentis, A.

    2016-12-01

    Fresh water scarcity is a global problem with local solutions. Agriculture is one of many human systems threatened by water deficits, and faces unique supply, demand, quality, and management challenges as the global climate changes and population grows. Sustainable agricultural water management is paramount to protecting global economies and ecosystems, but requires different approaches based on environmental conditions, social structures, and resource availability. This research compares water used by conservation agriculture in temperate and tropical agroecosystems through data collected from operations growing strawberries, grapes, tomatoes, and pistachios in California and corn and soybeans in Colombia. The highly manipulated hydrologic regime in California has depleted water resources and incited various adaptive management strategies, varying based on crop type and location throughout the state. Operations have to use less water more efficiently, and sometimes that means fallowing land in select groundwater basins. At the opposite end of the spectrum, the largely untouched landscape in the eastern plains of Colombia are rapidly being converted into commercial agricultural operations, with a unique opportunity to manage and plan for agricultural development with sustainability in mind. Although influenced by entirely different climates and economies, there are some similarities in agricultural water management strategies that could be applicable worldwide. Cover crops are a successful management strategy for both agricultural regimes, and moving forward it appears that farmers who work in coordination with their neighbors to plan for optimal production will be most successful in both locations. This research points to the required coordination of agricultural extension services as a critical component to sustainable water use, successful economies, and protected environments.

    The methodology for classifying areas according to soil properties for the vulnerability to a {sup 137}Cs contamination is of high importance to the preparedness related to nuclear and/or radiological accidents that lead to release of radionuclides to the environment with the consequent contamination of agricultural areas. The priority of research for agricultural areas should then focus on the surrounding areas of nuclear power plant that have higher probability of public exposure through the ingestion pathway. The objective of this work was to create a rank order for priority of areas to be mapped based on EMBRAPA database on soil properties. The 16 municipalities previously selected to define parameters for dose assessment simulations related to the Brazilian Nuclear Power Plants, located in the district of Angra dos Reis, Rio de Janeiro, have been investigated in order to create this rank order to direct the research on radio vulnerability mapping, considering their relevance to public exposure based on their agricultural productivity. The two aspects selected in this study account for the maximum loss of income and to the collective doses that can be averted due to the banning of agricultural products. These quantities are inputs to optimization analysis. The priority defined shall then guide research on both the adequate values for the transfer factors and on the agricultural countermeasures suitable to each area according to the cause(s) of their vulnerability and their typical agricultural crops.

    There is a close relationship between soil and air quality, on the one hand, and the exchange of greenhouse gases between the earth and atmosphere, on the other. International efforts by people such as soil conservationists and climatologists to control emissions of these gases and negotiations surrounding the Kyoto Protocol have increased the debate regarding the role of agricultural activities. From evaluation of both data available before global change became important and recent research efforts, much information on greenhouse gas emissions from Canadian agriculture has been gained. A summary is included of the contribution of Canadian prairie agriculture to emissions of carbon dioxide, nitrous oxide, and methane gas. A stress is placed on the subject of the carbon cycle and on how land management practices could influence soil carbon storage capacity. The potential for increasing this carbon storage capacity is described in relation to land use, historical changes in agricultural land, and recent observations on the influence of agricultural parctices, and obstacles to estimating changes in soil carbon dioxide emissions and carbon storage, and extending the estimates to large land areas are examined. Emissions of nitrous oxide and methane gas are considered in relation to the influence of agricultural management practices. (Abstract only)

    Full Text Available The paper studies the basic aspects of the system of agricultural insurance with state support in the Russian Federation at the present stage. The relevance of the study is related to the presence of enduring problem that lies in the fact that, despite some efforts by the State of legislative, organizational and economic measures, insurance of agricultural risks in Russia does not give the desired effect. The authors provide clear arguments about the necessity of state support for agriculture, particularly insurance, analyze the volume of subsidized funds from the federal budget for the payment of premiums to insurance companies. The article contains the analysis of the amount of insurance premiums for agricultural insurance in the world and the proportion of premiums collected by Russian agro-stakeholders. The nonoptimality of structure types of agricultural insurance with state support is indicated. The authors describe the main problems and disadvantages of the existing system of agricultural insurance with state support (lack of awareness, a small number of insurance products, high rates of insurance rates, etc., as well as some of the contradictions of the current legislation (the “double subsidies”. As a good example, a model of agricultural insurance in the United States is shown. The reasoned conclusions are made about the imperfection of the current legislation in the area of agricultural insurance, which largely meets the interests of the insurer, not of the insured. It was noted that agricultural insurance with state support in the Russian Federation is insignificant in scale of agricultural areas and in the country as a whole. The authors also make contradictory conclusions on the development of agricultural insurance market in Russia, mainly related to the fact that the system of agricultural insurance in the Russian Federation is only in its infancy.

    Based on the ecological and economic problems in Good Agriculture Practice (GAP) of Chinese material medica, we introduced the origin, concept, features and operative technology of eco-agriculture worldwide, emphasizing its modes on different biological levels of landscape, ecosystem, community, population, individual and gene in China. And on this basis, we analyzed the background and current situation of eco-agriculture of Chinese materia medica, and proposed its development ideas and key tasks, including: (1) Analysis and planning of the production pattern of Chinese material medica national wide. (2) Typical features extraction of regional agriculture of Chinese materia medica. (3) Investigation of the interaction and its mechanism between typical Chinese materia medica in each region and the micro-ecology of rhizosphere soil. (4) Study on technology of eco-agriculture of Chinese materia medica. (5) Extraction and solidification of eco-agriculture modes of Chinese materia medica. (6) Study on the theory of eco-agriculture of Chinese materia medica. Also we pointed out that GAP and eco-agriculture of Chinese material medica are both different and relative, but they are not contradictory with their own features. It is an irresistible trend to promote eco-agriculture in the GAP of Chinese material medica and coordinate ecological and economic development.

    This work briefly describes Brazilian colonization of the Paraguayan agricultural frontier, analyzes factors responsible for expelling population from Brazil and for attracting Brazilians to Paraguay, and assesses the economic and social consequences of immigration to the area. Paraguay's vast and sparsely populated agricultural frontier in areas outside the Central subregion underwent a process of intense colonization from the early 1960s to the mid-1980s. The Paraguayan government initiated an ambitious colonization program in 1963 to increase production, relieve population pressure and subdivision of small parcels in the Central subregion, encourage agricultural modernization, and produce a more diversified agriculture. Paraguayan agriculture in the early 1960s suffered from excessive concentration of land in a few hands and resulting exclusion of around 3/4 of workers from ownership and from any possibility of obtaining credit to fund technological improvements. Results of studies 2 decades after implementation of the colonization plan suggest that it has failed in significant areas. Although a considerable population redistribution alleviated pressure in the Central subregion, it apparently resulted more from spontaneous movement of peasants outside the colonization areas than from the official program. Concentration of lands is now occurring in the colonization area. Assistance for agricultural modernization and diversification of production in the peasant sector has been minimal. On the other hand, production of soy, wheat, and cotton for export increased substantially, because of an entrepreneurial agriculture capitalized by foreign as well as national interests The unmet goals of the colonization program would have required structural reforms rather than simple spatial redistribution of the population. Many of the colonists in the 1970s were Brazilian families displaced by mechanized agriculture in the southern states of Parana, Santa Catarina, and Rio

    Full Text Available The basic components of the American and Canadian public regulation regarding environment and agricultural ressources protection are review in this paper dealing also with the question of farmer'sliability to natural ressources preservation. The author take the position that the rise of environnemtal responsability of farmers can be the base for the development of a truly sustainable agriculture or a "environmentally-correct agriculture". Therefore, this new agriculture model can take place inside the contempory agro-food system based on model and productive families farms. After a brief description of the regulation under the American Farm Bill introducing the concept of farmer's "stewardship" (a notion not far away to the concept of "good management" or to the old French wording of "ménagement" of land launched by Olivier de Serres, a father of the French modern agfronomy, the article describe the Canadian approach which is quite similar. Finally, the author draw a conclusion in what he stand that the contempory family farming system can be viewed as a social form of agricultural production close to the theorical model of sustainable farming.
