Recommended Technologies

The report describes approximately 60 technological tools that could help farmers in sub-Saharan Africa and South Asia to increase agricultural productivity and reduce poverty.

Out of these, it focuses on eighteen technologies with great potential to improve agricultural productivity in the two regions. In general, the technologies identified with great potential impact are those that help to: (1) manage the natural resource base supporting agriculture (especially soil and water); (2) improve the genetic profile of crops and animals; (3) reduce biotic constraints (such as disease, pests, and weeds); and (4) provide affordable, renewable energy for farmers.

*Tier I tools and technologies are those that should be given the highest priority for development into specific applications in sub-Saharan Africa and South Asia today. These technologies largely already exist and have been proven successful, but they are new from the perspective of farmers in sub-Saharan Africa and South Asia because applications specific to the needs of farmers in these regions have not been developed or widely used.

**Tier II technologies include ideas that are emerging from advances in many fields that are considered a high priority for additional exploration. In concept, applications based on these technologies would have a great deal to offer farmers in the two regions. However, these technologies are not yet fully developed, so applications cannot be built based on them at this stage. Additional exploration is needed to determine their feasibility and how they could be implemented in the two regions.
