    Sammanfattning : Sub-Saharan Africa is today facing a big challenge regarding food deficiency and water scarcity due to climate change. One of these countries is Rwanda, a small landlocked country in the middle of Africa. Rwanda strongly depend on agriculture, both in the aspect of reducing poverty and hunger but also because their economy security depend on it. LÄS MER

  3. 2. The impacts of global warming and diet change on the virtual water consumption:  Estimating the present and future invisible virtual water resource use in East Africa

    Master-uppsats, Stockholms universitet/Stockholm Resilience Centre

    Författare :Julius Fröhlich; [2017]
    Nyckelord :water consumption; East Africa; CROPWAT; CLIMWAT;

    Sammanfattning : The production of food is the biggest water consumer and it is required to meet the growing demand of food from a growing population and changing diets. Water can be dislocated indirectly in its hidden virtual form in traded food products as the water that is needed to produce the product locally. LÄS MER

    Nyckelord :macaroni; Lantmännen; wheat flour; liquid fuel ethanol; winter wheat; Water footprint; Technology and Engineering;

    Sammanfattning : This study attempts to calculate the green blue and gray water footprint of the crop production of winter wheat and three derived winter wheat products: liquid fuel ethanol, wheat flour and macaroni. The calculations were done for Sweden for the period 2008-2010, covering an average of 80% of the annual winter wheat production. LÄS MER

  7. 5. Climate change impacts on crop yields and adaptive measures for agricultural sector in the lowlands of Lesotho

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Maoela Malebajoa; [2010]
    Nyckelord :climate change; A2 and B2 SRES; MAGICC SCENGEN; CROPWAT; Crop Yields; adaptive measures; Earth and Environmental Sciences;

    Sammanfattning : Summary: Climate change has emerged as the most outstanding of the environmental challenges and there is a necessity to evaluate its impacts on the vulnerable development sectors such as agriculture. In this study, spatially adjusted general circulation models and crop models were used to simulate climate change scenarios and the associated cereal crops yields for the western lowlands of Lesotho for the year 2030-2050 and 2080-2100.
