  1. Key Resource 2015-07-23 Climate change will have a huge impact on the world’s poorest people. 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. Key Resource 2015-02-16 Tropical root and tuber crops are consumed as staples in parts of the tropics and should be considered for their potential to produce impressive yields in small spaces. They provide valuable options for producing food under challenging growing conditions. Cassava and taro, for instance, are...  
  3. Key Resource 2014-04-01 ECHO frequently receives questions from members of our network, asking how available land could be used to grow food and/or create income to augment an otherwise non-agricultural project. Broadly speaking, they are asking how to begin an institutional agriculture project—a coordinated agriculture...

    2014-06-01 When you come across an especially promising local variety of a crop grown in your area, how can you enable other farmers to try out this variety? If a farmer gives you 30 seeds of an exceptional variety, how might you go about distributing these? How does seed flow happen in and among...

    2015-11-04 Active learning and exchange of knowledge are key to farmer adoption of beneficial agricultural innovations. Community health worker (CHW) and community animal health worker (CAHW) programs have led to a rich body of knowledge about extension, much of which is applicable to efforts aimed towards...  
  6. Key Resource 2015-09-21 The System of Rice Intensification (SRI) is a method of raising rice that produces substantially higher yields with the planting of far fewer seedlings and the use of fewer inputs than either traditional methods (i.e., flooding) or more “modern” methods (using mineral fertilizer or...  
  7. Key Resource 2014-01-01 In order to achieve high levels of agricultural productivity in the tropics at the lowest possible economic and ecological costs, we need to properly understand the relationship between nutrients in the soil and crop productivity. For this to happen, the current understanding needs to change. The...  
  8. 2015-01-20 Sorghum is primarily self-pollinated, meaning that a sorghum plant will accept pollen from its own flowers. Sorghum can also accept pollen from other sorghum plants (cross-pollination) by means of wind or insect transfer. Cultivated sorghum is generally cross-pollinated between 2 and 10%, with...  
  9. 2014-10-20 Worldwide, the number of insect pollinators has declined sharply in recent years. Beekeepers have experienced heavy loss of honey bee colonies; in the United States, the number of managed colonies is half of what it was sixty or seventy years ago (USDA). The number of wild pollinators has also...  
  10. 2015-05-19 A participatory learning approach, applied at each stage of a community development project, is crucial to reaching the level of stakeholder involvement needed for lasting, positive change. The use of participatory survey and planning methods in the development process encourages community...
