  1. 2012-01-01 Dawn Berkelaar, working with Dr. Martin Price and Danny Blank, featured this farming system in EDN 98. At that time, the technique was known as “Farming God’s Way” (FGW). Subsequently, the name was changed to “Foundations for Farming” (FFF); however, it continues to also be promoted as FGW. FGW...
  2. 1992-01-20 In simplest language, agroforestry is the production of trees and of non-tree crops or animals on the same piece of land. The crops can be grown together at the same time, can be grown in rotation, or can even be grown in separate plots when materials from one are used to benefit another....
  3. 2013-01-01 “Zai” is a term that farmers in northern Burkina Faso use to refer to small planting pits that typically measure 20-30 cm in width, are 10-20 cm deep and spaced 60-80 cm apart. In the Tahoua region of Niger, the haussa word “tassa” is used. English terms used to decribe zai pits include “planting...
  4. 1993-01-01 In every region of the world it is necessary to find or develop appropriate techniques for agriculture. A large part of the surface of the world is arid, characterized as too dry for conventional rain fed agriculture. Yet, millions of people live in such regions, and if current trends in...
  5. 2012-01-01 Asia makes up less than one third (30%) of the world’s land area and yet carries over half (56%) of the world’s population. Moreover, the average population density of Asia becomes a significant long-term problem when food production is considered. Some countries in Asia have a population density...
  6. 2010-01-01 For many years, conventional Western forestry methods have been applied, and exotic tree species promoted in Sahelian countries in order to combat desertification. Large and small projects were commissioned to curtail the assumed southward movement of the Sahara desert, but few made any lasting...
  7. 2010-01-01 Farming communities in the semi-arid tropical regions of Africa are becoming particularly vulnerable and face enormous challenges for their survival. Climate change, diminishing and unreliable rainfall, traditional mono culture cropping farming practices, high population growth, frequent famines...
  8. 1988-04-01 So you want to help people in the tropics. Beautiful! The tropics are waiting for you. No matter what your abilities, you can make life better for others in the tropics. Your concern for the physical and spiritual well-being of people can be translated into fruitful service. Your first asset is...
  9. 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...
  10. 2011-01-01 Lack of food security is one of the biggest challenges that Central Africans face each day as they toil in their gardens, trying to produce enough food to simply feed their families and afford other expenses in life such as health care or schooling for their children. Main factors limiting...
  11. 2010-07-01 Fish farming can generate high interest and excitement. It has great potential to produce high quality protein in relatively short time periods and in small areas. Fish farming is one way that resource poor farmers throughout the world can provide protein that is often lacking in the family diet...
