    Recommendations on optimization of monitoring contaminated sewage aimed at enviromental protection agxinst radioactive contamination at minimum cost are presented. The way of selecting water sampling technique depends on water composition stability and flow rate. Depending on the type of radionuclide distribution in the sewage one can estimate minimum frequency of sampling or number of samples sufficient for assuring reliability of the conclusion on the excess or non-excess of permissible radioactive contamination levels, as well as analysis assigned accuracy. By irregular contaminated sewage-discharge and possibility of short-term releases of different form and duration, sampling should be accomplished through automatic devices of continuons or periodic operation.

    Efficiency of decontamination measures in settlements contaminated as a result of the Chernobyl disaster (exemplified by the Kiev and Zhitomir Regions) is analyzed. Specific and total expenditures for decontamination of a single farm-stead and of a settlement on the whole are described. Estimation of a decrease in the external equivalent radiation dose of population as a result of decontamination measures undertaken is presented.

    The Peruvian Amazon is home to extraordinary biological and cultural diversity, and vast swaths of this mega-diverse region remain largely intact. Recent analysis indicates, however, that the rapid proliferation of oil and gas exploration zones now threatens the region's biodiversity, indigenous peoples, and wilderness areas. To better elucidate this dynamic situation, we analyzed official Peruvian government hydrocarbon information and generated a quantitative analysis of the past, present, and future of oil and gas activities in the Peruvian Amazon. We document an extensive hydrocarbon history for the region-over 104 000 km of seismic lines and 679 exploratory and production wells-highlighted by a major exploration boom in the early 1970s. We show that an unprecedented 48.6% of the Peruvian Amazon has been recently covered by oil and gas concessions, up from just 7.1% in 2003. These oil and gas concessions overlap 17.1% of the Peruvian Amazon protected area system and over half of all titled indigenous lands. Moreover, we found that up to 72% of the Peruvian Amazon has been zoned for hydrocarbon activities (concessions plus technical evaluation agreements and proposed concessions) in the past two years, and over 84% at some point during the past 40 years. We project that the recent rapid proliferation of hydrocarbon zones will lead to a second exploration boom, characterized by over 20 000 km of new seismic testing and construction of over 180 new exploratory wells in remote, intact, and sensitive forest areas. As the Peruvian Amazon oil frontier rapidly expands, we conclude that a rigorous policy debate is urgently needed in order to avoid the major environmental impacts associated with the first exploration boom of the 1970s and to minimize the social conflict that recently led to deadly encounters between indigenous protesters and government forces.

    Declining soil and productivity is a major problem facing smallholder farmers in the central highlands of Kenya.This decline is caused by continuous cultivation of soils without adequate addition of external inputs in form of manure and fertilizers. Use of inorganic fertilisers is low due to high costs that are beyond the reach of majority of smallholder farmers. A multidisciplinary on-farm participatory was therefore initiated in the main maize growing areas of the central highlands of Kenya in 2000 with the main objective of addressing this problem. Results after four cropping seasons indicate that organic residues such as leguminous shrubs (Leucaena trichandra and calliandra calothrysus), herbaceous legumes (Crotalaria ochroleuca and Mucuna pruriens), Tithonia diversifolia, farm yard manure alone or with combination of 30 kg N ha -1 from inorganic sources can be used effectively to improve maize performance in the region.Over the four seasons under study, these organic residues gave an average mean maize grain yield in the range of 3.4 to 4.0 t ha -1 which is more than 1.0 t ha -1 that farmers in the area get from their farms. when the farmers were asked to select technologies that they wanted to test, majority selected tithonia, calliandra, leucaena and farm yard manure. This was attributed to availability of these organic resources at the farm level as tithonia could be cut along the roadsides and more than 80% of the farmers' own livestock. These results through preliminary, indicate that organic resources being tested in this trial are effective in improving maize yields and farmers are willing to try these on their farms
