  1. 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...  
  2. 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...

  4. Key Resource 2015-09-21 SRI involves the use of a combination of management practices that optimize growing conditions for rice plants, particularly in the root zone. It was developed in Madagascar in the early 1980s by Father Henri de Laulaníe, a Jesuit priest who spent over 30 years in that country working with...

  7. 1995-10-10 This new edition builds on the explosion of research on sustainable agriculture since the late 1980s. By separating myth from reality, Miguel Altieri extracts the key principles of sustainable agriculture and expounds on management systems that "really work." Providing case studies of sustainable...  
  8. In this book we chose to explore the ways in which agroecologists can enhance agricultural productivity to benefit rather than marginalize small producers.  
  9. Maintenance of biological diversity and nutrient cycling mechanisms are global principles that are common to all agroecosystems and therefore essential in the design of sustainable agricultural systems. Regional or site-specific factors include climate, soils and socio-economic preferences and...
     
  10. The purpose of this book is to provide a simple synthesis of the research on novel agroecosystems and technologies and an analysis of ecologically based farms, for the purpose of establishing the scientific basis of alternative agriculture. This book is an urgent call to all students of...
