    Abstract : Photosynthesis is probably the most important process for allowing life to develop into the diverse forms we see today. In this process, solar radiation is used to convert CO2 into biomass. From this process, we obtain oxygen to breathe, sources of food (plant biomass), and the potential for clean and sustainable energy. READ MORE

  5. 13. Rainfall variability, soils and land use changes in the Ethiopian highlands

    Author : Staffan Rosell; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; rainfall change; soil productivity; tef; land-use changes; South Wollo; water harvesting;

    Abstract : Most farmers in the Ethiopian highlands are dependent on rain-fed agriculture. The indigenous cereal tef is the most important crop for the farmers in the highlands. The central highland is an environmentally fragile area and a marginal area of Ethiopia with a recurring problem for the farmers to sustain an adequate agricultural production. READ MORE

  6. 14. Marginal and Virtual Water for Sustainable Water Resources Management in Syria

    Author : Khaldoon A. Mourad; Centrum för Mellanösternstudier (CMES); []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Arid and semiarid Middle Eastern countries generally, and Syria in particular, face serious water shortage problems and challenges with water sustainability. Climate change, population growth, and economic development play a major role in decreasing available water resources per capita. READ MORE
