Variation in Staple Food Prices in Eastern and Southern Africa: Causes, Consequences and Policy Options AgEcon
AAMP Policy Briefing 1 January, 2010 This brief summarizes the policy implications of three thematic papers and seven country background papers prepared for the COMESA-ACTESA policy seminar on “Variations in staple food prices: Causes, consequences, and policy implications.” There is little controversy about the need for governments to support staple food markets with infrastructure, market information, agricultural research, and other public goods. However, many of the most costly agricultural programs in eastern and southern Africa involve raising food prices to protect farmers, lowering food prices to protect consumers, and reducing volatility in food prices through a variety of mechanisms including tariffs, export restrictions, public trading in staple...

Violence, Political Instability, and International Trade: Evidence from Kenya’s Cut Flower Sector AgEcon
Muhammad, Andrew; D'Souza, Anna; Amponsah, William A..
Abstract: We assess whether and how violence and political instability affect trade between developed and developing countries considering the special case of EU imports of Kenyan roses after the 2007/08 post-election violence and political instability in Kenya. Using the Rotterdam model to estimate EU demand for roses from Kenya and other global competitors, we find evidence of a structural change in the import growth rate for Kenya, approximately equivalent to an 18.6% tariff. These results highlight the importance of non-tariff barriers to trade and contribute to the growing literature on the role of insecurity and instability in hindering international trade.

Wage Rentals for Reproducible Human Capital: Evidence from Ghana and the Ivory Coast AgEcon
Schultz, T. Paul.
Education, child nutrition, adult health/nutrition, and labor mobility are critical factors in achieving recent sustained growth in factor productivity. To compare the contribution of these four human capital inputs, as expanded specification of the wage function is estimated from household (LSMS) surveys of The Ivory Coast and Ghana. Specification tests assess whether the human capital inputs are exogenous, and instrumental variable techniques are used to estimate the wage function. Smaller panels from the Ivory Coast imply the magnitude of measurement error in the human capital inputs and provide more efficient instruments to estimate the wage equation. The conclusion emerges that weight-for-height and height are endogenous, particularly prone to...

Was There a Credit Crunch in Namibia Between 1996-2000? AgEcon
Ikhide, Sylvanus.
Commercial bank credit is a useful tool for promoting economic growth especially at the early stages of development. It has been observed that between 1996 and the early part of 2000, the growth rate of real credit to the private sector declined significantly in Namibia. This period coincided with observed strong demand for commercial bank loans. There has therefore been public discourse on the possibility of a restriction in the supply of credit by commercial banks and hence the occurrence of a credit crunch in the economy since commercial bank lending capacity did not fall. This paper attempts to provide some evidence in this regard by examining the main determinants of commercial bank credit in the economy and ascertaining if credit has been demand or...

Welche Landwirtschaft für Afrika? Akzeptanz und Potenzial biologischer Methoden Organic Eprints
Nicolay, Gian L..
Afrika, dieser grosse, vielseitige und verkannte Kontinent kämpft zurzeit heftig um die Ausrichtung seiner Landwirtschafts – und Ernährungspolitik. Die Lage ist dramatisch. Südlich des Sahel leiden von den knapp 800 Mio Menschen mindestens ein Drittel an Hunger und Misere. Ein Grossteil der Ackerböden und Weidegründe ist stark beschädigt und gibt nur noch Bruchteile der üblichen Erträge her. Wälder und Savannenlandschaften sowie Biodiversität stehen unter Dauerdruck und fallen ungebremst dem Landhunger zum Opfer. Hat die biologische Landwirtschaft das Potenzial, wesentlich zur Ernährungssicherheit, zum guten Leben und zur Regeneration der Bodenfruchtbarkeit beizutragen? Das Forschungsinstitut für biologischen Landbau (FiBL) hat gute Gründe, daran zu...

What are the Key Constraints in Technical Efficiency of Smallholder Farmers in Africa? Empirical Evidence from Kenya AgEcon
Owuor, George; Shem, Ouma A..
The idea that smallholder farmers are reasonably efficient has triggered much debate in Sub-Saharan Africa. Indeed, efficiency of smallholder farmers has implications for choice of development strategy; reason being that Sub-Saharan countries derive over 60% of their livelihoods from smallholder agriculture and rural economic activities. This paper evaluates factors that promote production efficiency among smallholder farmers in Kenya as avenues for policy intervention. A production frontier function was fitted to a random sample derived from a survey carried in 2007. Results show that all conventional inputs had the expected significance. On the inefficiency indicators, ownership to farmland, attendance to agricultural workshops, access to credit and...

What is the irrigation potential for Africa? A Combined Biophysical and Socioeconomic Approach AgEcon
You, Liangzhi; Ringler, Claudia; Nelson, Gerald C.; Wood-Sichra, Ulrike; Robertson, Richard D.; Wood, Stanley; Guo, Zhe; Zhu, Tingju; Sun, Yan.
Although irrigation in Africa has the potential to boost agricultural productivities by at least 50 percent, food production on the continent is almost entirely rainfed. The area equipped for irrigation, currently slightly more than 13 million hectares, makes up just 6 percent of the total cultivated area. Eighty-five percent of Africa’s poor live in rural areas and mostly depend on agriculture for their livelihoods. As a result, agricultural development is key to ending poverty on the continent. Many development organizations have recently proposed to significantly increase investments in irrigation in the region. However, the potential for irrigation investments in Africa is highly dependent upon geographic, hydrologic, agronomic, and economic factors...

What Kind of Agricultural Strategies Lead to Broad-Based Growth: Implications For Country-Led Agricultural Investment Programs AgEcon
Jayne, Thomas S.; Boughton, Duncan.
Without renewed attention to sustained agricultural productivity growth, most small farms in developing countries will become increasingly unviable economic and social units. Sustained agricultural productivity growth and poverty reduction will require progress on a number of fronts, most importantly increased public goods investments to agriculture; a policy environment that supports private investment in input, output, and financial markets and provision of key support services; a more level global trade policy environment; supportive donor programs; and improved governance. Subsidies, if they are focused, appropriately conceived, effectively implemented, and temporary, can play a complementary role but should not – based on both the Asian and African...

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.

Why are Fresh Produce Prices So Unstable in Lusaka? Insights for Policy and Investment Priorities. AgEcon
Hichaambwa, Munguzwe; Tschirley, David L..
Daily quantities of tomato, rape and onion entering Soweto market in Lusaka fluctuate dramatically. The market does a remarkable job of moderating the impact on prices of these unstable quantities, through stabilizing mechanisms such as short-term storage of tomato and rape by traders and consumers, longer-term storage of onion by traders, direct sourcing of rape from farm areas by retail traders, and exportation of tomato and onion outside Lusaka. Yet even with these stabilizing mechanisms, wholesale prices are highly variable, with negative effects on farmers and consumers. Reducing variability requires investments in four areas: (a) improved control of production environments by farmers through irrigation, better access to inputs and greater agronomic...

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...

Yellow fever in Africa and the Americas: a historical and epidemiological perspective J. Venom. Anim. Toxins incl. Trop. Dis.
Chippaux,Jean-Philippe; Chippaux,Alain.
Abstract Yellow fever was transported during the slave trade in the 15th and 16th centuries from Africa to the Americas where the virus encountered favorable ecological conditions that allowed creation of a sustainable sylvatic cycle. Despite effective vector control and immunization programs for nearly a century, yellow fever epidemics reemerged in many Latin American countries, particularly Brazil. The emergence or reemergence of vector-borne diseases encompasses many intricate factors. Yellow fever outbreaks occur if at least three conditions are fulfilled: the introduction of the virus into a non-immune human community, presence of competent and anthropophilic vectors and insufficiency of prevention and/or adequate management of the growing outbreak....
