Workshop on Agricultural Transformation in Africa: Abidjan, Côte D'Ivoire, September 26-29, 1995 AgEcon
Ba, Moussa Batchily; Staatz, John M.; Farrelly, Laura L.; Camara, Youssouf; Dimithe, Georges.
At the initiative of USAID, the ADB, MSU, and INSAH, 40 researchers, policy makers and private-sector entrepreneurs from 19 countries, representing 20 African and international organizations, met in Abidjan for a continent-wide workshop to debate issues related to transformation of African agriculture. The Abidjan workshop built on previous discussions organized by Winrock International, the World Bank, USAID (AFR/SD/PSGE/FSP) and IFPRI concerning the key challenges (food insecurity, poverty, and environmental degradation) that need to be addressed while fostering a structural transformation of African agriculture.

Market Liberalization and Agricultural Intensification in Kenya (1992-2002) AgEcon
De Groote, Hugo; Kimenju, Simon Chege; Owuor, George; Wanyama, Japheter.
This study analyses the impact of the liberalization on the intensification of maize production in Kenya. It first analyses the impact of liberalization on input and output prices, followed by an analysis of farmer practices comparing two major farmer surveys, from 1992 and 2002. The results show that liberalization has had a general positive impact on the evolution of prices, with a decrease of input/output price ratios. However, fluctuations of maize prices has become very high and, combined with a decrease of marketing by the marketing board, has increased the uncertainty in maize production. The liberalization has also resulted in a decrease in extension services. Fortunately, farmers have an increased access to credit services. The combined effect of...

Constraints to the Development of Commodity Exchanges in Africa: A Case Study of ZAMACE AgEcon
Sitko, Nicholas J.; Jayne, Thomas S..
The development of agricultural commodity exchanges in Africa has become an increasingly popular strategy for addressing some of the ills plaguing African food markets, including poorly developed risk management systems, high transaction costs, and limited price discovery. However, despite substantial support from donors and, in some cases, national governments, commodity exchanges in most African countries are having difficulties getting off the ground. While previous studies (Rashid, Winter-Nelson, and Garcia 2010) highlight the fact that low trade volumes passing through African commodity exchanges limit their development, the question of why exchanges are thinly traded remains poorly understood. Using the Zambian Agricultural Commodity Exchange...

Why market institutions disfavor smallholder farmers’ compliance with international food safety standards: Evidence from Kenya, Zambia and Ethiopia AgEcon
Okello, Julius Juma; Narrod, Clare A.; Roy, Devesh.
This paper examines the high value chains (HVC) for green bean exports from Africa to identify the critical points at which exporters exercise great caution in preventing produce contamination with pathogens and pesticide residues. It then examines the control points that pose greatest threat to continued participation of smallholder farmers in the HVC and discusses the strategies African countries have used to maintain smallholder farmers in the green bean HVC. The paper identifies six critical control points. Among these, smallholders are most threatened with exclusion from HVC at two control points. At those points the farmer must make costly lumpy investments to meet the standards. To overcome the likelihood of smallholders being excluded from HVC at...

Has Kenyan Farmers’ Access to Markets and Services Improved? Panel Survey Evidence, 1997-2007 AgEcon
Chamberlin, Jordan; Jayne, Thomas S..
This report uses panel data on 1,267 smallholder households to monitor changes in their access to markets and services. We find that Kenyan smallholders’ proximity to infrastructure, markets, and services has improved markedly over the last decade. These improvements, however, have not been uniformly distributed over either time or space. Farmers in high-potential areas of the country continue to enjoy closer proximity to most kinds of markets and services compared to low-potential areas, but the greatest relative improvements over the 1997-2007 period have been in areas of medium and low potential. We also distinguish between public and private investments in examining changes in smallholders’ access to markets. Changes deriving from public investments...

EDUCATING AGRICULTURAL RESEARCHERS: A REVIEW OF THE ROLE OF AFRICAN UNIVERSITIES AgEcon
Beintema, Nienke M.; Pardey, Philip G.; Roseboom, Johannes.
The number of higher-education institutions and the students enrolled in them has grown rapidly throughout Africa since the early 1960s. The number of universities increased from less than 20 in 1960 to nearly 160 by 1996; student numbers grew from 119,000 to almost two million over the same period, yet enrollment ratios in Africa continue to lag well behind developed and other-developing country norms. Funding for higher-education in Africa kept pace with the expanding institutional base during the 1960s and 1970s, but has fallen well behind the growth in student numbers since 1980. The pattern of the development of the agricultural sciences has matched the general pattern of development of the higher-education sector. Three quarters of the countries in...

Who Should be Interviewed in Surveys of Household Income? AgEcon
Fisher, Monica G.; Reimer, Jeffrey J.; Carr, Edward R..
This study tests the null hypothesis that it is sufficient to interview only the household head to obtain accurate information on household income. Results show that using a husband’s estimate of his wife’s income does not produce statistically reliable results for poverty analysis. Estimates of the wife’s income provided by the husband and wife are in agreement in only six percent of households. While limiting interviews to one person has the advantage of reducing the time and expense of household surveys, this appears detrimental in terms of accuracy, and may lead to incorrect conclusions on the determinants of poverty.

Government responses to the world food crisis 2007-08: A political economy perspective AgEcon
Maas, Sarah; Matthews, Alan.
This paper examines the performance of African agri-food exports to the EU market over the first decade of the new millennium. The EU is Africa’s single largest export market absorbing just half of all African agri-food exports. Countries are grouped according to the preferential trade regime they enjoy to enter the EU market: North African countries under EuroMed agreements; least developed African countries under the Everything but Arms arrangement; other African countries under the Cotonou Agreement; and South Africa under its Trade, Development and Cooperation Agreement. Despite these preferences, Africa appears to be losing market share. A shift-share analysis confirms that, with the exception of the African Mediterranean countries, the...

Regional Integration in Developing Countries: Some Lessons Based on Case Studies AgEcon
Shams, Rasul.
The main focus of this paper is the question if the success of regional integration organisation in developing countries is, in fact, dependent on factors like similarity of their economic structure, market size or lack of commitment. It is shown that there are also other more important institutional and politico-economical reasons to explain the functioning of such organisations in developing countries. Case studies of ECOWAS and SADC will be used to discuss this question. It is also very often argued that southsouth integration is inferior to north-south integration. This will be discussed considering the case of MERCOSUR as an example.

Diversity of Communities and Economic Development: An Overview AgEcon
Ranis, Gustav.
This paper reviews the literature on the impact of ethnic diversity on economic development. Ethnically polarized societies are less likely to agree on the provision of public goods and more likely to engage in rent seeking activities providing lower levels of social capital. Initial conditions are important determinants of adverse development outcomes. The role of decentralization, democracy and markets as potential remedies are discussed. The paper then presents a number of preliminary hypotheses on the relationship between diversity and instability in order to stimulate future research.

An Impact Study of the Economic Partnership Agreements (EPAs) in the Six ACP Regions AgEcon
Fontagne, Lionel; Laborde, David; Mitaritonna, Cristina.
This article intends to present a very detailed analysis of the trade-related aspects of Economic Partnership Agreements (EPAs) negotiations. We use a dynamic partial equilibrium model – focusing on the demand side – at the HS6 level (covering 5,113 HS6 products). Two alternative lists of sensitive products are constructed, one giving priority to the agricultural sectors, the other focusing on tariff revenue preservation. In order to be WTO compatible, EPAs must translate into 90 percent of bilateral trade fully liberalised. We use this criterion to simulate EPAs for each negotiating regional block. ACP exports to the EU are forecast to be 10 percent higher with the EPAs than under the GSP/EBA option. On average ACP countries are forecast to lose 70...

A Ricardian analysis of the impact of climate change on African cropland AgEcon
Kurukulasuriya, Pradeep; Mendelsohn, Robert.
This study examines the impact of climate change on cropland in Africa, using a Ricardian cross-sectional approach. Relying on farm data from an 11-country survey of over 9500 farmers, annual net revenue is regressed on climate and other variables. The study confirms that current climate affects the net revenues of farms across Africa. Applying these results to possible future climates reveals that dryland farms are especially climate sensitive. Even as early as 2020, climate change could have strong negative impacts on currently dry and hot locations. By 2100, dryland crop net revenues could rise by 51% if future warming is mild and wet but fall by 43% if future climates are hot and dry. The crop net revenues of currently irrigated farms are likely to be...

Unpacking the Meaning of “Market Access” AgEcon
Chamberlin, Jordan; Jayne, Thomas S..
Improving farmers’ access to markets is widely recognized as a major development challenge. A review of the literature suggests that indicators of market access may bear little relationship to the specific processes of interest and hence provide misguided evidence of the impacts of improved market access. This paper attempts to “unpack” the dimensions of market access and, in the process, uses farm survey data from Kenya to investigate changes in multiple indicators during the post-liberalization period. Findings show that market access conditions experienced by rural Kenyans exhibit considerable variation across time, space, and indicator type. We suggest ways in which structured hypothesizing and sensitivity analysis may strengthen empirical treatments...

Food Insecurity in Sub-Saharan Africa: New Estimates from Household Expenditure Surveys AgEcon
Smith, Lisa C.; Alderman, Harold; Aduayom, Dede.
Reducing food insecurity in the developing world continues to be a major public policy challenge, and one that is complicated by lack of information on the location, severity, and causes of food insecurity. Such information is needed to properly target assistance, evaluate whether progress is achieved, and develop appropriate interventions to help those in need. This research report explores a new method of measuring food insecurity using food data collected as part of household expenditure surveys. Such surveys are routinely undertaken by numerous national governments throughout the developing world, but in the past the resulting food data remained largely unexploited for the purposes of measuring food insecurity. Using data from 12 Sub-Saharan African...

Improving water use efficiency under worsening scarcity: Evidence from the Middle Olifants sub-basin in South Africa AgEcon
Walter, Teresa; Kloos, Julia; Tsegai, Daniel W..
With the political changes in South Africa in the early 1990s, the South African government introduced a reform process in the entire water sector with the goal of a more enhanced and equitable water management system. This paper analyzes existing water allocation situations and applies a nonlinear optimization model to investigate the optimal intra- and inter-regional allocations in the Middle Olifants sub-basin of South Africa. Results show higher benefit from inter-regional water allocation. Reducing water supply levels to conform to the sustainable water supply policy, it can be shown that although water supply is reduced by approximately 50%, total benefits from water are only reduced by 5% and 11% for inter- and intra-regional allocation regimes...
