Abstract

Africa is estimated to have great potential for agricultural production, but there are a number of constraints inhibiting the development of that potential. Spatial data are increasingly important in the realization of potential as well as the associated constraints. With crop production data generated at 5-minute spatial resolution, the paper applies the spatial tobit regression model to estimate the possible impacts of improvements in transport accessibility in East Africa. It is found that rural accessibility and access to markets are important to increase agricultural production. In particular for export crops, such as coffee, tea, tobacco, and cotton, access to ports is crucial. The elasticities are estimated at 0.3–4.6. In addition, the estimation results show that spatial autocorrelation matters to the estimation results. While a random shock in a particular locality would likely affect its neighboring places, the spatial autoregressive term can be positive or negative, depending on how fragmented the current production areas are.

Abstract

This paper uses a global general equilibrium simulation model to quantify the effects of lifting economic sanctions on Iran with and without strategic responses. Iran benefits the most, with average per capita welfare gains ranging from close to 3 percent, in the case when Iran's crude oil exports to the European Union recover to half their pre-embargo level, to 6.5 percent, in the best case of complete recovery of oil exports to the European Union, successful domestic reforms that enable a strong supply response, and increased market access for Iranian exports in developed markets. Iran could achieve benefits close to the upper range if Gulf Cooperation Council oil exporters limit their crude oil exports to support the oil price. If they do nothing, however, the price of oil will decline by 13 percent in the case of complete recovery of oil exports to the European Union, leaving net oil importers better off and net oil exporters worse off.

Abstract

Africa has great potential for agriculture. Although international commodity prices have been buoyant, Africa’s supply response seems to be weak. A variety of constraints may exist. Using the case of Tanzania, the paper examines the impact of market connectivity, domestic and international, on farmers’ crop choices. It is shown that the international market connectivity, measured by transport costs to the maritime port, is important for farmers to choose export crops, such as cotton and tobacco. Internal connectivity to the domestic market is also found to be important for growing food crops, such as maize and rice. Among other inputs, access to irrigation and improved seed availability are also important factors in the crop choices of farmers. The size of land area is one constraint to promote the crop shift. The paper also reports the finding that farmers are not using market prices effectively in their choice of crop, even after the endogeneity of local prices is taken into account. Document type: Book

Abstract

griculture in Tanzania accounts for 28 percent of the country's Gross Domestic Product (GDP) and employs 80 percent of its labor force. The sector is also an important source of export revenues. The data and findings presented in this report provide a summary of the performance of the agriculture sector in Tanzania using a set of indicators covering six areas. These are: 1) access to and availability of certified seed; 2) availability of and access to fertilizer; 3) access to farm machinery, particularly tractor hire services for land preparation; 4) access to agricultural and agro-enterprise finance; 5) the cost and efficiency of transporting agricultural commodities; and 6) measures of policy certainty and uncertainty as perceived by private investors and the effects these have on the enabling environment for producers and agribusinesses. The Agribusiness Indicators (ABI) team conducted interviews with Government agencies, private firms (fertilizer importers, seed companies, tractor importers and distributors, transporters), commercial banks, farmer-based organizations, donors, and Non Governmental Organizations (NGOs). The ABI program is pilot testing an initial set of indicators on the ease (or difficulty) of operating agribusinesses in African countries. The indicators are used to assess whether the countries have an enabling environment that is conducive to agribusiness investment, competitiveness, and ultimately agriculture-led growth.
