3Investing in food production Background readings
for this week
- World Bank, World Development Review 2008
Agriculture for Development - released October 2007, first WDR to address
agriculture since 1986, whose theme was Trade and
Pricing Policies in World Agriculture WDR 1982
was also on ag. - W.A. Masters (2005), Paying for Prosperity How
and Why to Invest in Agricultural Research and
Development in Africa, J. of Int. Affairs,
58(2), 3564. - Review for a special issue on Finance Challenges
of the Millennium Development Goals. - Rockefeller Foundation (2006), Africas Turn A
New Green Revolution for the 21st Century. - Launch document for AGRA, the Alliance for a
Green Revolution in Africa - Glenn D. Stone (2010), The Anthropology of
Genetically Modified Crops. Annual Review of

(not agricultural science or economics)
insiders are much more pro-GMO
4Investing in food production Outline for today
- Why a special focus on agriculture?
- Why do some regions, like Africa, lag behind?
- How does farm size matter for productivity?
- How has foreign aid for food productivity
changed? - How has private agricultural RD changed?
5Investing in food productionWhy a special focus
on agriculture?
- In low-income places where food is scarce,
agriculture is - The largest sector
- most people, most use of natural resources, most
exports - The poorest sector
- most poor people, most degradation of resources,
most taxation of exports
6Farming is what poor people do!

for Development. Washington The World Bank.
7Farming is what poor people doShould donors
join the exodus from agriculture?
- In low-income places where food is scarce,
agriculture is - The largest sector
- most people, most use of natural resources, most
exports - The poorest sector
- most poor people, most degradation of resources,
most taxation of exports - In general, agriculture offers
- low productivity relative to other sectors
- variable productivity relatively to other sectors
- limited prospects for growth or future stability
- The overwhelming flow of investment is to
off-farm activity - the route out of poverty is out of agriculture
- Within rural areas richer farmers invest in
nonfarm rural enterprises - Within poor countries individuals and households
migrate to urban areas - Across countries migration, trade and investment
favors non-farm work - Why not focus on urbanization, to buy the food
people need?
8Investing in food productionWhy a special focus
on agriculture?
- In any given year
- Food availability is limited, so someone must
grow food - Objective 1 is productivity, so even more people
and resources can move to faster-growing sectors - Nonfarm jobs are limited, so the poorest farmers
have no choice - Objective 2 is productivity, to relieve poor
farmers poverty, during the transition before
they move to faster-growing sectors - Among non-farmers, the poorest spend more on food
- Objective 3 is productivity, to reduce the cost
of food and allow people to spend more on other
things - And eventually
- Farmland remains available, and food production
remains important for environmental, cultural and
social reasons - Objective 4 is productivity, for
multifunctional objectives - Investment in agriculture is always about
productivity, - to fuel other sectors farm output rarely grows
very fast
9Investing in food productionWhy a special focus
on agriculture?
The classic formulation is
- Increasing supply, so as to meet rising demand
demand growth population growth
elasticityincome growth - Increasing exports, so as to buy imports for
other things - Reducing labor use, so as to free workers for
other things - Generating capital, for investment in other
things - Increasing rural demand, for buying other things
10Investing in food productionWhats different now?
- In starting AGRA, the Alliance for a Green
Revolution in Africa, the Rockefeller Foundation
(2006) argued - Africa missed out on farm productivity gains
elsewhere, - RD-driven productivity gain requires
philanthropic action, beyond what companies
governments can do. - Some reasons for the neglect of agricultural
productivity are - Gains are non-excludable (private firms cant
capture value) - Gains are international (national governments
cant either) - Gains are difficult to observe and predict (need
impact data)

28Investing in food production Todays story so
far
- Food productivity growth helps to accelerate
transition to non-farm activity, and to
alleviate poverty during the transition - Africa has faced particular geographic hurdles in
food productivity, and demographic pressure
driving farm size down - Smaller farms are not necessarily less
productive they - adopt innovations faster for seeds, fertilizer
other divisible, labor-using inputs - and adopt more slowly for machinery and other
lumpy, labor-saving inputs - they achieve highest total productivity when land
is distributed equitably, - But in any case reduced land per farmer reduces
farm income, unless offset by productivity growth
29The need for more food does gradually slow down
30But is the agricultural engine slowing down too
soon?
31One reason for slower growth is declining Green
Revolution aid
32Since the mid 1980s we have contributedvery
little to Africas farm productivity gains
What happened to the level and mix of foreign aid?
Foreign aid to African agriculture fell to about
US1 per capita (vs. 4/pers. in health and 38
in total ODA).
