Discussion paper

It is widely believed that land tenure insecurity under a customary tenure system leads to socially inefficient resource allocation. This article demonstrates that land tenure insecurity promotes tree planting, which is inefficient from the private point of view but could be relatively efficient from the viewpoint of the global environment. Regression analysis, based on primary data collected in Sumatra, indicates that tenure insecurity in fact leads to early tree planting.

In the wake of the food crises of the early 1970s and the resulting World Food Conference of 1974, a group of innovators realized that food security depends not only on crop production, but also on the policies that affect food systems, from farm to table. The International Food Policy Research Institute (IFPRI) was founded in 1975 and for the past four decades has worked to provide solid research and evidence for policy options to partners in donor and recipient countries.

Agriculture, including fisheries and forestry, accounted for 36.4 percent of Myanmar’s GDP in 2010-2011. Approximately 69 percent of the total population of 59.78 million (2010-2011) lives in rural areas and 61.2 percent of the total labor force is employed by the agricul-ture sector (MOAI 2012). The government has designated the agriculture sector as a main pillar of the economy and is dedicating vari-ous efforts and investments to achieve greater progress in the sector. Rice is the primary crop, followed by maize, pulses, and oil seeds.

In response to slow growth in the agricultural sector and as part of a general shift towards a more market-oriented economy, the Government of Egypt started liberalizing the agricultural sector in 1987. Controls over wheat production and marketing were eliminated and wheat producer prices were brought closer to international levels. As a result, there has been remarkable increases in wheat crop area and yields, causing wheat production to triple from 1986 to 1998.

Working paper

Ethiopia’s national development strategy, A Plan for Accelerated and Sustained Development to End Poverty for 2005/06 to 2009/10 (PASDEP) places a major emphasis on achieving high rates of agricultural and overall economic growth. Consistent with the PASDEP, Ethiopia is also in the process of implementing the Comprehensive Africa Agriculture Development Programme (CAADP) together with other African governments.

This paper investigates empirically the factors that influence real agricultural wage rates in Ghana, based on 1957 to 1991 data. The Johansen cointegration framework is used to examine long-run relationships among agricultural and urban wage rates, the domestic terms of trade between agriculture and non-agriculture, urban unemployment, capital stock in agriculture and the size of the rural population. An error correction model is then used to investigate short-run dynamic relationships among the variables.

"Large private investments in biofuels are presently underway in Mozambique. This paper uses an economywide model to assess the implications of these investments for growth and income distribution. Our results indicate that biofuels provide an opportunity to enhance growth and poverty reduction. Overall, the proposed biofuel investments increase Mozambique's annual economic growth by 0.6 percentage points and reduce the incidence of poverty by about six percentage points over the 12-year phase-in period. However, the benefits depend on production technology.

In his insghtfull but unfinished work, Dharm Narain drew attention to the behavior of prices as one of the important factors determining the extent of poverty in rural India. His empirical investigations, summarized in Gunvant Desai's contribution to this volume (chap. 1), provide strong prima facie evidence of such influence. Dharm Narain found that rural poverty is not only inversely related to the level of output per head of the rural population, as established in Ahluwalia (1978a), but also positively related to the level of prices.

In an effort to inform strategic options to improve agricultural productivity, we examine the impact of social service expenditures on the marginal productivity of agricultural inputs. Increasing agricultural productivity is often advocated as a way to reduce poverty, especially in sub-Saharan Africa, where many people still rely on agriculture as their main source of income. Unfortunately, limited national budgets are often focused on meeting short-term needs rather than on making longer-term, growth-enhancing investments in agriculture and rural areas.

This paper analyzes the effects of climate change on hydrology and water resources in the Limpopo River Basin of Southern Africa, using a semidistributed hydrological model and the Water Simulation Module of the International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT). The analysis focuses on the effects of climate change on hydrology and irrigation in parts of the four riparian countries within the basin: Botswana, Mozambique, South Africa, and Zimbabwe.
