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.
