SSA – world’s future breadbasket

• While crop yield gaps in other regions has narrowed leading to reduced food production from yield increase, yield gap is SSA is the widest

• About 90% of the remaining 1.8 billion ha of global arable land in developing countries is in LAC and SSA (Bruinsma 2009)

• Recent land grabbing attests to SSA’s future BB role – 66% of 234 million ha acquired by foreign investors came from SSA (Anseeuw, et al 2012)

• But challenges limiting high agricultural productivity in SSA need to be addressed to tap its large potential

SSA’s pattern of land use & its relationship with international aid

• ODA support as % of GDP of recipient country is highest in countries with largest cropland expansion

Botswana & DRC offer important lessons for cropland use change in SSA

What drives Botswana to attaining such favorable outcomes with ltd resources and DRC to poor outcomes while it is endowed with abundant natural resources?

Major drivers of cropland extent & implications

Impact on cropland area

Implications

Ag R&D ↓,↑ More investment in R&D to tap SSA large potential

International aid ↑,↓ More aid required in land based sectors to reach threshold

Access to roads ↑ Road improvement should be accompanied with enhancing environmental regulations

Population density ↑,↓ Boserupian induced intensification

Agricultural export ↓ Remunerative prices enhance intensification

Gov’t effectiveness ↑ Increase capacity of gov’t effectiveness to level to prevent deforestation

Land tenure security ↓ Land security enhances intensification

Poverty & population density

↑ Target dev’t programs to rural poor to increase intensification
