Summary of productivity outcomes from Africa case studies for the Foresight project (Foresight, 2011; Pretty et al., 2014)
| Thematic focus | Area improved (ha) | Mean yield increased (ratio) | Net multiplicative increase in food production (1000 t year–1) |
|---|---|---|---|
| Crop variety and system improvements | 391 060 | 2·18 | 292 |
| Agroforestry and soil conservation | 3 385 000 | 1·96 | 747 |
| Conservation agriculture | 26 057 | 2·20 | 11 |
| Integrated pest management | 3 327 000 | 2·24 | 1418 |
| Horticulture and small-scale agriculture | 510 | ND | ND |
| Livestock and fodder crops | 303 025 | ND | ND |
| Novel regional and national partnerships and policies | 5 319 840 | 2·05 | 3,318 |
| Aquaculture | 523 | ND | ND |
| Total | 12 753 000 | 2·13 | 5786 |
ND, no data, largely because horticulture, livestock and aquaculture are additive components to systems, increasing total food production but not necessarily yields.
