Seven villages in southeastern Kenya surround Mt. Kasigau and depend on the mountain's cloud forest for their water supply. Five of these villages have regularly experienced water shortages, and all village water supplies were contaminated with Escherichia coli bacteria. There is a need to economically find new sources of fresh ground water. Remote sensing offers a relatively quick and cost-effective way of identifying areas with high potential for ground water development. This study used spectral properties of features on Landsat remote sensing imagery to map linear features, soil types, surface moisture, and vegetation. Linear features represented geologic or geomorphologic features indicating either shallow ground water or areas of increased subsurface hydraulic conductivity. Regarding...

Remote power systems with advanced storage technologies for Alaskan villages

Bongs - a new fertilizer plant

Remote Alaskan communities pay economic and environmental penalties for electricity, because they must import diesel as their primary fuel for electric power production, paying heavy transportation costs and potentially causing environmental damage with empty drums, leakage, and spills. For these reasons, remote villages offer a viable niche market where sustainable energy systems based on renewable resources and advanced energy storage technologies can compete favorably on purely economic grounds, while providing environmental benefits. These villages can also serve as a robust proving ground for systematic analysis, study, improvement, and optimization of sustainable energy systems with advanced technologies. This paper presents an analytical optimization of a remote power system for a hypothetical Alaskan village. The analysis considers the potential of generating renewable energy (e.g., wind and solar), along with the ...

Use of multipurpose trees in hill farming systems in western Nepal

In an attempt to overcome inadequacies perceived in the approach to providing energy to village communities using the conventional Khadi and Village Industries Commission biogas plant as well as the Janata model, a biogas digester has been developed suitable for a farmer having only one hectare of land. The information on gas yields and other data from a variety of substrates in a laboratory digester are presented. The digester itself consists of a chamber underground into which the influent flows through a channel. Gas is collected in a dome which constitutes the upper part of the digestion chamber and is maintained under pressure by water. The dome can be made of any suitable material such as plastic, ferrocement and brick and mortar. The upper part of the chamber itself is exposed to sun light which enhances microbial growth. Water which surrounds the dome ensures a minimum of temperature variation. 3 references.

Islamic social capital and networking

A study of two villages identified 55 woody perennial species that are maintained in contour strips across slopes and around fields in a subsistence farming system. These trees and shrubs produced fodder and firewood and reduced erosion hazards, allowing crop production on very steep slopes where it would otherwise be very difficult. Data on basic farm management, production of crops, etc. are discussed. The performance of the system is assessed and its strengths and weaknesses highlighted. It is suggested that several locally available medicinal plants could be incorporated into the system.

Health and social impacts of biomass gasification for household energy in rural China: Assessment from three perspectives and emergent insights from their synthesis

effect of gamma rays, fertilization and gibberellin on inter cropped sesame and peanut crops

Solid fuels such as coal, wood, and crop straw supply some fraction of household cooking and heating fuel for more than one billion people in China. As these fuels do not generally combust cleanly in household stoves, their use levies large health and environmental burdens, particularly in rural regions. Production of clean-burning fuels from agricultural residue offers one prospect for mitigating health and social burdens imposed by household use of solid fuels. This dissertation explores the question: how might production of clean-burning household fuels from agricultural residues affect human health and social conditions in rural China? I approach this question from three perspectives. First, a technically plausible but currently unproven village-scale energy technology is explored in a scenario bounded by natural resources and substantiated by engineering specifications, estimates of indoor exposures to air pollution, and epidemiological analyses. This analysis ...

Baobab (Adansonia digitata L.) fruit production in communal and conservation land-use types in Southern Africa

This study reported on the performance of a passive solar radiant floor heating system designed for standard energy-saving farmhouses in northeast China. Weather data in the region was analyzed in terms of solar radiation, temperature, humidity and light levels. The heating characteristics of the building materials such as windows, doors, walls and roofs were also analyzed along with the indoor thermal environment of the farmhouse. The heating load was then calculated along with the size of the thermal storage element and the area of the collector element. The passive solar radiant floor heating system was designed for heating during the winter and cooling in summer. According to the results, the heating characteristics of the system have the potential to improve farming villages environment and the use of renewable energy.

Assessing farm-level agricultural sustainability over a 60-year period in rural eastern India

British Library Electronic Table of Contents (United Kingdom)

Agricultural sustainability is a vital parameter to be ascertained locally and globally if food security is to be achieved and maintained. Agricultural sustainability is the combined product of social, economic and ecological sustainability. It is also a function of temporal and spatial variations, a fact which indicates that area-specific sustainability indices need to be designed. We present here an Agricultural Sustainability Index (ASI) for rural eastern India and use it to calculate the ASI for 150 farms for three decades over a 60-year period, viz., 1950?1960, 1980?1990 and 2000?2010 for a representative Indian village of Gangapur (25?83?N, 85?65?E). The ASI was calculated using 30 variables, 10 each of social, economic and ecological sustainability. An extensive questionnaire-based ...

Radioiodine dosimetry and prediction of consequences of thyroid exposure of the Russian population following the Chernobyl accident

Off-grid power generation is meant to supply remote or rural area, where grid connection is almost impossible in terms of cost and geography, such as island, aborigine's villages, and areas where nature preservation is concern. Harnessing an abundance renewable energy sources using versatile hybrid power systems can offer the best, least-cost alternative solution for extending modern energy services to remote and isolated communities. The conventional method for off-grid power generation is using diesel generator with a renewable energy (RE) technology utilizing solar photovoltaic, wind, biomass, biogas and/or mini/micro hydro. A hybrid technology is a combination of multiple source of energy; such as RE and diesel generator and may also include energy storage such as battery. In our design, the concept of solar hybrid system is a combination of solar with diesel genset and battery as an energy storage. The main objective of the system are to reduce the cost of ...

Municipal solid waste management in Lebanon: the need for an integrated approach

In the early period after the Chernobyl accident, analysis of patterns of "1"3"1I exposure of the human thyroid showed that contaminated milk was the basic source of "1"3"1I intake among the inhabitants of Russia. The equipment and techniques used for measurement of the "1"3"1I content in the thyroids of these individuals are described in this work. A model of the "1"3"1I intake, taking into account protective actions, and a method of thyroid dose calculation are discussed. The mean thyroid dose and frequency distributions of the thyroid doses to inhabitants of towns and villages of the Bryansk, Tula and Orel regions of Russia are presented. The mean dose to the thyroids of children living in the villages was 2 to 5 times higher than the dose to adult thyroids; for children living in the towns, the mean dose was 1.5 to 12 times higher. The mean thyroid mass in adult inhabitants of the Bryansk region was 27 g, which exceeded the value for a ...

Results of radon concentration measurements in some regions of Russia

Two separate studies address the major issues of deforestation in developing countries, namely, Does deforestation seriously impair the soil-plant system. and How can a steady supply of wood fuels be guaranteed with diminishing natural forest. In Chapter 1, twenty-six cross-sectional and time series studies of soil properties in the US and ten countries between the tropics were examined to determine the changes associated with deforestation in soil organic C, total N, exchangeable Ca, Mg, and K, cation exchange capacity, available P, bulk density, and pH. Deforestation was associated with significant changes in these soil properties. Only bulk density and avaiable P showed any tendency to return to pre-clearing levels. Differences in soil response to deforestation according to climate and age of parent material were related to temperature, rainfall, vegetation, soil acidity, and organic matter production and decomposition on each site. In Chapter 2, a multiobjective linear program ...

Photovoltaic mini power plants for integration in the third world and Eastern Europe. Market analysis aimed at health and education

The Sierra Madre Occidental of western Mexico is composed dominantly of Mid-Tertiary felsic and subordinate mafic volcanic rocks with only sparse outcrops of non-volcanic rocks. There are widely scattered but small exposure of plutonic rocks but regionally metamorphosed rocks are not known to occur in the Sierra. To this date the only known area where plutonic and metamorphic xenoliths have been found is near the village of Basaseachic in western Chihuahua where thick outcrops of the Cascada Tuff occur. The xenoliths are the only known occurrence of regionally metamorphosed rocks for a distance of about 400 km between exposures of Precambrian rocks to the west in Sonora and the east in central Chihuahua. Non-volcanic xenoliths from a few cm to about one meter in diameter occur most abundantly in the upper portions of the Cascada Tuff. They can be divided into four main groups in decreasing order of abundance as follows: (1) coarse-grained phaneritic felsic igneous ...

Influence of nutrition and suckling patterns on the postpartum cyclic activity of swamp buffaloes

Energy is a critical factor which determines the progress of rural development. Energy is therefore an area of concern. The quality, availability and cost of conventional energies, plus the associated environmental effects are a growing problem - not only for the health infrastructure but also for agriculture and domestic life. This is true not only in developing countries where the fast growing industries and urban populations demand a soaring proportion of available energy at the expense of the rural communities, but also in the poorest countries with weak energy infrastructure. Renewable energies, much studied in the last 20 years, can meet the needs of rural health and education services and communities by providing high quality, low cost, non-polluting energy. Solar energy, in particular, has the flexibility to produce electricity, heat and cooling. Solar technologies, furthermore, are backed by an established and experienced industry. This report proposes to meet the energy needs ...

Monthly report of activities: APRIL 1, 1969

Two studies were conducted to investigate the effects of nutrition and suckling patterns on the ovarian cyclicity of postpartum buffaloes. In Study 1, which was conducted on an institutional farm, two different diets were fed to 24 buffaloes during late gestation and postpartum period. Restricted (twice daily) suckling began on day 30 postpartum in half the animals on each diet. The body weight of both ad libitum suckled and twice daily suckled groups declined during the postpartum period, irrespective of the diet fed. Buffaloes subjected to restricted suckling lost less body weight and re-established ovarian cyclicity earlier than those suckled ad libitum. In Study 2, which was conducted under village conditions, temporary calf removal for 72 hours on days 91-93 postpartum in anoestrous buffaloes induced the re-establishment of ovarian cyclicity within 14 days.

On 21 October 1994, three brothers entered a waste repository at Tammiku, Estonia, without authorization and removed a metal container enclosing a caesium-137 source. During the removal the source was dislodged and fell to the ground. One of the men picked up the source, placed it in his pocket and took it to his home in the nearby village of Kiisa. Very soon after entry into the repository he began to feel ill, and few hours later he began to vomit. The man was subsequently admitted to hospital with severe injuries to his leg and hip and died on 2 November 1994. The injury and subsequent death were not attributed to radiation exposure, and the source remained in the man's house with his wife and stepson and the boy's great-grandmother. The boy was hospitalized on 17 November with severe burns on his hands, and these were identified by a doctor as radiation induced. The authorities were alerted, and the Estonian Rescue Board recovered the source from the house. The ...

Adult abundance, biting behavior and parity of Anopheles aquasalis, Curry 1932 in two malarious areas of Sucre State, Venezuela

A study was made for the purpose of electrification of unelectrified zones of the mountainous areas in developing countries using extremely small hydroelectric power facilities. The target for this project is a development of a micro hydroelectric power system with a size of about 5kW, which is estimated regarding that 1 village has 80 houses and each house needs electricity of 60W. In the study, the low-head system using a weir of irrigation channels in Subang pref. of West Java state was selected by the evaluation of access, stability of flow rate, natural conditions, etc. The hydroelectric power plant is of a flow-in method in which water is taken from the left bank and is injected/discharged to the downstream of the left bank. As the hybrid complementary power source, hybrid battery with a two-hour charging time at peak and a capacity of 3.5kWh was considered. When estimating the construction cost of the hybrid micro hydroelectric power system and equalizing by ...

Abstract in english The principal vector of malaria in eastern Venezuela, Anopheles aquasalis, is exophagic and exophilic. Control using indoor insecticide house sprays has failed to lower the number of malaria cases. Therefore, studies were initiated in two villages of the eastern coastal state of Sucre to better understand this vector's biology and develop a more integrated control program. An. aquasalis was found to have a crepuscular biting behavior with a major peak at dusk and a minor (more) peak at dawn. Mosquitos were collected more outdoors than indoors. Forty-seven percent of the biting took place before people went to bed (22:30 hr) and 69% of the mosquitos biting during this time period bite outdoors. Outdoor biting could be the reason why indoor spraying alone did not lower malaria cases. Seasonal abundance was greater in the rainy season compared to the dry season. Seasonal parous rates were high (78.3%-100%) and similar indoors and outdoors and ...
