Crop yields have already gone down in the tropics and are projected to drop by 15-30% by 2080 in Africa, South Asia, and Central America (Hoffman 2013). Some countries could reach a 50% loss of agricultural productivity; in...  
  2. Abstract,International Journal of Agronomy, 2017 Smallholder livestock farmers who depend on natural communal grazing lands are particularly vulnerable to climate change as well as to food insecurity and should be encouraged to grow drought-tolerant fodder crops. Moringa oleifera is a highly...
     
  3. Abstract, Pakistan Journal of Nutrition, 2011 This study was carried out to assess the nutrient composition of some unconventional and local feed resources available in Senegal so as to use them as protein supplement sources in the diets of indigenous chickens to enhance their productivity. Ten...

  5. 2020-01-01 In a tropical setting, growing seedlings can be difficult. A major factor of concern for nursery production is water logging (Zhu et al. 2007). During the rainy season, oversaturated soils can effectively suffocate root systems of a seedling by restricting flow of oxygen and other important...  
  6. 2020-01-01 Soil quality, also known as soil health, is the capacity of the soil to function – how well it fills the roles we need it to, whether in a natural or managed ecosystem. A variety of measures are used to gauge soil health; although we can use these characteristics as indicators of soil quality,...
