   University essay from Industriell miljöteknik

   Author : Elaine Leong; [2013]
   Keywords : Water; China; Water crisis; Falkenmark Water Scarcity Index; Water stress; Physical and Economical Water Scarcity; Water Stress Indicator Taking Environmental Water Requirements Into Account; Map of Global Threats To Human Water Security And River Biodiversity; Climate change; Hai River; Huai River; Yellow River; Yangtze River; Pearl River; Liao River; Songhua River; Tarim River;

   Abstract : Several studies indicates China is experiencing a water crisis, were several regions are suffering of severe water scarcity and rivers are heavily polluted. On the other hand, water is used inefficiently and wastefully: water use efficiency in the agriculture sector is only 40% and within industry, only 40% of the industrial wastewater is recycled.

3. 17. Causes and Consequences of Land Degradation : Conversion of Agricultural land to Non-Agricultural usages in Bangladesh: A case study on ‘Keyain’ village of Munshigonj District

   University essay from Institutionen för naturvetenskap, miljö och teknik

   Author : Abu Sayeed; [2013]
   Keywords : Land degradation in Bangladesh;

   Abstract : During the last few years the agriculture sector is facing danger in many ways. Conversion of agricultural land in non-agricultural uses is one of the main reasons to follow. Why the land is decreasing, how it is converted to non-agricultural purposes is the important matter of concern at present. READ MORE

4. 18. Simulations of water balance conditions and cli-mate variability for Sustainable Agriculture and Energy in the Lower Rufiji Basin.

   University essay from KTH/Mark- och vattenteknik

   Author : Rajabu Hamisi; [2013]
   Keywords : Adaptation; Agriculture; Climate Change; CoupModel; Hydropower; SWAT; Water Balance;

   Abstract : This study provides a long-term understanding of the impact of climate varia-bility and land use on seasonal water balance conditions for sustainable agricul-ture development, hydropower generation and ecosystem stability in the Lower Rufiji Basin. The severity of soil drought, extreme flooding and salinity intru-sion in the lower Rufiji floodplains are currently increasing smallholder poverty and enhance the sensitivity on the natural wetlands for shifting farming and livestock pastures.

   Abstract : Almost 50 % of drinking water in Sweden comes from aquifers. The sustainability of groundwater resources in Stockholm County is threatened by increased salinity although most of the drinking water comes from Lake Mälaren. READ MORE

6. 20. Long Term Environmental Modelling of Soil-Water-Plant Exposed to Saline Water.

   University essay from KTH/Mark- och vattenteknik

   Author : Leila Pourfathali Kasmaei; [2012]
   Keywords : CoupModel; Drip and surface irrigation; Leaching fraction; Soil evaporation; Transpiration; Salinization;

   Abstract : The impact of long term management strategies of irrigation with saline water in semi-arid region of Gordonia, South Africa is the highest interest to optimize water consumption, soil conservation, and crop yield for sustainable water allocations to human food production and ecosystem without irreversible damages to soil and water body. An integrated ecosystem assimilation, in shape of soil-water storage model based on physical approach for 30-year simulation run defined in form of digital ecosystem modelling with help of CoupModel tool to assemble together the most important underlying processes of soil hydraulics, irrigation demands, leaching fraction, evapotranspiration, salt transport.
