  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. 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...  
  3. 2013-01-20 Currently, seeds of all carrot varieties grown in hot sub-Saharan Africa are imported from regions with temperate climates such as Europe and USA. It has not been easy to produce carrot seeds in hot Africa, because carrots require exposure to cold temperatures (vernalization) to induce flowering....  
  4. 2013-10-20 In Chiang Mai, Thailand, during the late1990s, I became aware of farming practices that utilized beneficial microorganisms to enhance small farm resources and production in the tropics. Such techniques, enabling soil recovery and improving smallscale crop and livestock production, blended...  
  5. 2013-04-20 Sometimes the smallest of things can impact human health beyond all proportion to their size. Trace elements are an example of this. Trace elements in an amount that is either above or below certain thresholds in soil, animal feed, or the human diet can have important impacts on the health of...  
  6. 2013-07-20 The System of Rice Intensification (SRI; see EDN 70, and http://sri.ciifad.cornell.edu/) has changed the way millions of farmers plant rice. The management practices used with SRI have also now been tried with many other crops. Here we present an update about crops that have demonstrated...  
  7. 2013-10-20 Does a planting basin, like a zai pit, make much of a difference in soil moisture on a sandy soil? Because water leaches through sand rather quickly, you might expect that planting depressions would not have a significant impact on soil moisture. With the soil in ECHO research plots in South...  
  8. 2015-01-20 To gain an understanding of the value of moringa prunings as a soil fertility input, we wanted to know the concentration of N, P, and K in woody versus leafy biomass of moringa trees. Plant tissue was collected at the second leaf harvest, about 2 months after the final manure application.

What steps toward recovery can you take in such a situation? And what actions can be taken beforehand to minimize the damage from a large-scale,...  
  10. 2015-04-30 Like all farmers, smallholder farmers require support services to provide production inputs, to market surplus production and to contribute other services like contract mechanization (for land preparation, post-harvest processing, initial value added), credit, etc. Within smallholder agriculture...
