  1. 21. Participatory watershed management to decrease land degradation and sediment transport in Kagera and Nyando catchments of Lake Victoria basin

    University essay from Tema vatten i natur och samhälle

    Author : James Gunya Kenge; [2009]
    Keywords : Kagera and Nyando catchments; Lake Victoria basin; land degradation; participatory watershed management; policy;

    Abstract : Attention to participatory watershed management is increasing across the developing world as soil erosion continues to degrade agricultural land; reservoirs and irrigation infrastructure are clogged with sediment. The realization of the importance of watersheds is crucial for sustainable utilization especially in developing countries where rural livelihoods and economies are highly dependant on the exploitation of natural resources.

  3. 22. Phosphorus in agricultural soils around the Baltic Sea : comparisons of different laboratory methods as indices for phosphorus leaching to waters

    University essay from SLU/Dept. of Soil and Environment

    Author : Ann Kristin Eriksson; [2009]
    Keywords : Soil phosphorus methods; phosphorus losses; agricultural catchments; Baltic states;

    Abstract : Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. READ MORE

    Abstract : Wetlands water quality is influenced by the anthopogenic activities in the catchments’ areas. Wastewaters from the urban storm, agricultural runoff and sewage treatment often end up in wetlands before flowing to rivers, lakes and the sea. READ MORE

  5. 24. Statistical and neural network ananlysis of pesticide losses to surface water in small agricultural catchments in Sweden

    University essay from SLU/Dept. of Soil Sciences

    Author : Stina Adielsson; [2005]
    Keywords : pesticide loss; Vemmenhög; multiple linear regression; pesticide properties;

    Abstract : The aim of this thesis was to explain variations in pesticide leaching from the pesticide properties (DT50, koc, log Pow, Sw and combinations of these) using multiple linear regression and artificial neural networks. The data came mainly from Vemmenhög, a catchment nine square kilometres in size dominated by agriculture, located in the south of Sweden. READ MORE
