objective: the world is currently facing with various problems including water and soil pollution as well as a major threat to the health of the citizens due to the advancement at human civilization, technology development, pesticides and chemical fertilizers application, the increasing exploitation of natural resources by the agricultural sector and the increasing usage of fossil energy. there...

abstract herbicides are the main sources of soil and water pollution in paddy fields. herbicides mobility to the surface and ground water is a major concern for human health and the environment. it is, therefore, necessary to investigate their fate and their interactions in natural ecosystems. to meet this purpose, field experiments were conducted to measure kinetic of thiobencarb dissipation i...

This paper reports the preliminary results obtained from an FAO/IAEA coordinated research project (CRP) involving eight countries. Results obtained are discussed with respect to sources and sinks of water and nutrients in water conservation zones that help farmers to use water when it is required. Three types of water conservation zones, namely farm ponds, wetlands and riparian buffer zones wer...

nowadays soil erosion is considered as a serious threat to human's life and his welfare. when soil erosion not properly controlled, the fertility would gradually decrease. adoption of appropriate soil conservation practices along with socio-economic factors' assessment can be used to increase farmers' awareness and acceptance of soil conservation, and to diminish soil erosion dam...

We illustrate a strategy for valuation of forest ecosystem services by studying the demand for its weak complement, agricultural labor –a commodity that has market prices. In our case study forest protection in Ruteng Park of Flores, Indonesia, provides soil conservation benefits to farmers living near the protected area. Econometric analyses of forest hydrology and household data shows that so...

Karst rocky desertification is a geo-ecological problem in Southwest China because of nature and man-made factors, which restricts the development of local economic and social. Soil and water erosion is one of the most harmful form of rocky desertification, but the management methods still keep in the exploratory stage. Biological soil crust is the organic complexes of biotic components includi...
