Impacts of Investments and Livelihood Strategies in Less Favored Areas: Evidence from Asia, East Africa and Central America: 

Impacts of Investments and Livelihood Strategies in Less Favored Areas: Evidence from Asia, East Africa and Central America John Pender, IFPRI USAID Seminar on Marginal Areas, Feb. 3, 2005

Outline: 

Outline Background and rationale What are less-favored areas (LFA’s)? Why be concerned about them (or not)? Returns to investment in LFAs India China Uganda Impacts of investments and livelihoods on production, income, land degradation in LFAs Ethiopia Uganda Honduras Conclusions and implications

What are “less-favored areas”?: 

What are “less-favored areas”? Less-favored areas are less favored by nature or by man, including areas with low agricultural potential, due to limited rainfall, poor soils, steep slopes, etc. (biophysical constraints); or limited access to infrastructure (e.g., roads and irrigation) and markets (socioeconomic constraints)

Slide5: 

Less-favored areas include most of semi-arid and arid tropics of Asia and Africa mountain areas of Asia, Latin America and Africa hillside areas in Central America and Asia forest margins of humid and sub-humid tropics of Africa, Latin America and Asia

Why be concerned about less-favored areas?: 

Why be concerned about less-favored areas? Over 1 billion people live in such areas These areas were largely bypassed by the Green Revolution Problems of low agricultural productivity, poverty, and natural resource degradation severe and worsening in many such areas Problems in these areas give rise to conflict, emigration to other areas, negative environmental consequences

The Conventional Wisdom: 

The Conventional Wisdom Emphasize public investments in agricultural R&D, infrastructure, etc. in favored areas where returns are higher Benefits of increased food production, income and foreign exchange from favored areas will spread through lower food prices and migration to favored areas Resources improve due to reduced pressure on fragile resources in less-favored areas

Challenges to the Conventional Wisdom: 

Challenges to the Conventional Wisdom Rapid population growth continues in less-favored areas Problems of poverty and resource degradation getting worse in many cases Evidence of diminishing returns to investment and increasing environmental problems in favored areas Evidence of higher or comparable returns to investments in less favored areas in some countries, and greater impact on poverty (“win-win” strategies) Some evidence suggests possibility of “win-win-win” strategies benefiting the environment alongside economic growth and poverty reduction

Impacts of Investments and Livelihoods on Production, Income, and Land Degradation in LFA’s: 

Impacts of Investments and Livelihoods on Production, Income, and Land Degradation in LFA’s Evidence from three countries (Pender and colleagues) Ethiopia – highlands of Tigray and Amhara Surveys of 934 households in 198 highland villages Uganda 451 households in 107 villages Honduras hillsides 385 households in 95 villages in 19 municipalities

Conclusions/Implications: 

Conclusions/Implications High returns to many public investments in LFA’s and greater impact on poverty in India, China, and Uganda There are investments/livelihoods that can increase crop production, income, and/or reduce land degradation in less-favored areas; e.g. Tigray: stone terraces, reduced tillage and burning, manure, alternative livelihoods, market development Uganda: livestock production, other livelihood strategies Honduras: manure, fertilizer, machinery/equipment, livestock production But trade-offs are often apparent; e.g. Effects of technical assistance in Uganda and Honduras Effects of education in Uganda Effect of farm work in Honduras

Conclusions/Implications (2): 

Conclusions/Implications (2) Impacts of interventions/investments are context dependent, linked to local comparative advantages: Low returns to cereals in Tigray and low potential Amhara  low returns to fertilizer, extension, credit Higher returns to livestock, beekeeping, tree planting, nonfarm activities in Tigray High returns to cereals and fertilizer in high potential Amhara Higher returns to bananas, livestock in highlands of Uganda Development strategies for less-favored areas should take local comparative advantages and disadvantages into account
