ISS 330a Social Science Perspectives on Africa AGRICULTURAL DEVELOPMENT IN SUB-SAHARAN AFRICA Professor Rick Bernsten, Department of Agricultural Economics O O O O O (3/21/200) KEY QUESTIONS O Why is agriculture important in Sub-Saharan Africa? What is agricultural development? What is Sub-Saharan Africa’s food problem? How well has agriculture performed in Sub-Sahara Africa? Why has Sub-Saharan Africa’s agricultural sector performed poorly? What do Sub-Saharan African and developed countries need to do to improve agriculture? Prospects for the future? GENERALIZATIONS ARE DANGEROUS! O Sub-Saharan Africa is very agriculturally, environmentally, socially, politically diverse O All generalizations have exceptions O All of the following generalizations do NOT apply to any single country!! O Each country must be analyzed as a CASE STUDY to understand the causes of its agricultural development successes and failures I. Why Is Agriculture Important In Sub-Saharan Africa? Overall economy o Major source of employment o Major share of GDP o Major source of export earnings Rural population: most people (50-90%) live in rural areas, depend on agriculture for o Food–produce crops for own household o Cash–sell surplus food crops and cash crops to generate cash income Urban population: growing rapidly due to rural-urban migration o Need inexpensive food o Food prices affect industrial wage rates, inflation rate II. What Is Agricultural Development? o Economic transformation (historical process): Gradual shift in the economy characterized by a decline in the importance of agriculture as a percent of GDP and employment o Long term goal: Reduce the importance of agriculture Increase the importance of manufacturing, services sectors o Paradox: Must first increase agricultural productivity in order to transform the economy into a manufacturing/service based economy Can’t just “industrialize now” Agricultural development is a “precondition” for overall development: The “ENGINE” of development 1 Development (def.) creating the conditions for the realization of human potential o Increase GDP/capita (income) o Increase quality of life, access to education, health, food, political freedom, etc. o The challenge: Most countries w/large agric population, rapid population growth III. What Is Sub-Saharan Africa’s Food Problem? o Famine? (def.) acute food shortages resulting in widespread loss of life (Figure: deaths) Causes: The “trigger/agent”: floods, drought, pest infestation, war => food shortages The “real” cause: human/political failure to provide food to the affected people (Examples: Sudan, Somalia, North Korea etc.) Incidence: decreasing problem (domestic/international relief efforts) (Figure: FEWS) (Figure: Food Aid) o Hunger/malnutrition? (def.) chronic food shortage (calories and/or protein) that reduces peoples ability to work productively, can cause retardation in children Cause: Primary cause: poverty, lack of income to purchase food on the market Contributing causes: discrimination (women, minorities), environmental stress, low agricultural productivity (yields) Incidence: 1/3 Sub-Saharan Africa’s population is hungry (Figure) o Food Security (def.) ability to acquire a nutritionally adequate diet throughout the year by: Producing own food: farmers Buying food: rural non-farm, urban workers Transfers: food aid from own government, international community o Supply and Demand for Food Demand factors: o Population increase o Income increase o Changing consumption patterns Supply factors: o Increasing in land area farmed (historical strategy) o Increase in output/yield per hectare (modern strategy) Example: Population growth (P): 3.0% (Doubling time=22 years) Income growth (Y): 2.0% Income elasticity of demand (E): 0.7% Annual increase in demand: 4.4% D = % P + ((% Y) (E)) Historically in the U.S. : 1-2 %/year increase in food production o Indicators of agricultural development: Success: increasing food/capita ==> declining domestic food prices (U.S., Europe) Failure: decreasing food/capita ==> rising domestic food prices IV. How Well Has Agriculture Performed In Sub-Saharan Africa? o Types of farming systems (crops & livestock) in Sub-Saharan Africa Subsistence (disappearing): labor intensive, purchase no inputs, consume all of harvest Semi-Substance (most common): labor intensive, purchase some inputs (fertilizer, insecticides, 2 seed), market some of harvest (good years) (Figure) Commercial/market oriented (small but growing): purchase yield-increasing inputs, sell most of output o Key crops in Sub-Saharan Africa Importance of crop varies by region/environment (Figure) Grains (calories) o Corn (semi-arid areas) (Figure) o Sorghum/millet (arid areas) (Figure) o Rice (wet areas) Legumes (protein) o Groundnuts/peanuts (Figure) o Cowpeas (black-eyed peas) Tubers (calories) o Cassava (Figure) o Yams (Figure) Export crops (earn foreign exchange) o Coffee (highland areas) o Cacao (chocolate) o Oil palm (Palmolive soap) o Tea (highland areas) o Experiences since 1960: both success and failure Success in increasing total food (grain) production (Figure) Failure in increasing per capita food (grain) production (Figure) Low cereal yields/slow rate of yield increases (Figure) But Some countries have done better than others (Why?) V. Why Has Sub-Saharan Africa’s Agriculture Performed Poorly? Many interdependent factors!! o Colonial History Neglected food crop improvement, focused on export-crops for Europe Failed to train local agricultural scientists o Harsh physical environment Rainfall: limited in 2/3 of continent, highly seasonal (3-5 months) Soils: old, poor quality/low fertility, soil prone to erosion (heavy rains) Warm weather: high evaporation rate, insect & diseases Diverse ecosystems: crop technology needed for many different niches (Figure) (new varieties, crop recommendations) Tsetse fly: 20% of land uninhabitable, limits cattle production re) o Limited physical infrastructure Poor quality roads: hard/expensive to deliver inputs/market crops Shortage of transport vehicles: limited stock makes marketing difficult/expensive o Underdeveloped social capital High illiteracy: farmers can’t read instructions (insecticides/ fertilizers labels) Low education level: farmers have minimal knowledge of scientific agriculture Weak health systems: human productivity reduced by diseases (malaria, AIDS) o Weak supporting institutions Agricultural research: 3 Little ir II o o o o o o o o o Underfunded, so slow to develop new agricultural technologies Agricultural extension: Poorly trained/short of vehicles, so can’t assist farmers Most farmers are women, most extension agents are men Agricultural credit: Often not available to small farmers/women farmers Crop marketing: Inefficient government parastatals, offer farmers low/fixed prices Control marketing (farmer must sell crops to the government) Farmer Organizations: Weak, minimal influence on government’s agricultural policies Domestic political/policy factors Wars/conflicts: o Disrupts agricultural production (Zimbabwe–production increased 20% at end of war for Independence) o Drains resources from investments in agriculture One -Party States/corruption: o Not responsive to needs of the people Misguided economic policies: government interventions distorted the economy o Emphasized industrialization over agriculture o Taxed agriculture (export taxes) to generate government revenue o Overvalued currency: made imports cheap, exports expensive (reduced demand) o Discouraged private enterprise (capitalism is bad!) External factors Declining & unstable commodity prices: o Many countries dependant on a few export crops/minerals for foreign exchange o Declining world prices for Africa’s export crops, prices vary greatly from year-to-year Heavy debt burden: o Debt repayment drains resources from investing in agriculture, etc. Declining development assistance (foreign aid): o US/Europe reducing total aid (“donor fatigue”) (Figure) o US aid declining, especially for agriculture (Figure, Figure) o US aid small ($55capita) , compared to other developed countries What Do Sub-Saharan African and Developed Countries Need To Do To Improve Agriculture? African Countries o The African farmer: a victim of circumstance “Poor but efficient”: uses available resources in “best” possible way Limited by constraints: poor policies, lack of new technologies, harsh environment, etc. Uses traditional technology, but need science-based yield-increasing technologies o Continue policy reforms (“structural adjustment”) o Invest in people and institutions (especially agricultural research and extension) o Give greater priority to agriculture (Uganda, Ghana, Mali) o Promote peace and reconciliation (South Africa) Developed Countries 4 o o o o Debt relief: Should forgive debt of the poorest nations Development assistance: Should give more aid to countries which make policy reforms, especially focusing on the agricultural sector (US aid now only $55 per capita, 0.02 % of GDP, <1% of US federal budget) VI. Prospects For Guardedly optimistic Population: recent evidence of fertility decline, Population Bomb predicted catastrophe but didn’t happen Policy Reforms: will stimulate investment, expand exports, create jobs, Asian Drama: Doom and gloom for India in the 1960s didn’t happen Democracy/Governance: trend towards more open political systems Debt relief/foreign id: growing recognition of need for some debt, but prospects for more aid are uncertain Agriculture: growing recognition of key role of agriculture Institutions: NGO’s are making a contributions to strengthening local organizations Uncertainties? Civil unrest: poverty, resource degradation may fuel conflicts Globalization/free trade: impact unclear, Sub-Saharan Africa may find it difficult to compete in an opener world economy Physical & social infrastructure: Sub-Saharan Africa may find it difficult to make the needed investments, AIDS pandemic will have a devastating impact on economies 5
