A Case Study of Regulation in Zambia’s Cotton Sector. AgEcon
Tschirley, David L.; Kabwe, Stephen.
Cotton is an unquestioned success of Zambia’s turn towards a market economy. After privatization in late 1994, seed cotton production rose from 32,000 metric tons (mt) to about 180,000 mt a decade later (three-year averages centered on 1994 and 2005). The number of farmers involved in the sector grew similarly, yields trended upwards (though slowly), and the country dramatically improved the quality of its lint, becoming the outstanding performer in Sub-Saharan Africa in this regard by the mid-2000s. Yet the sector has experienced two serious crashes since reform, both involving rampant credit default by farmers supported with seasonal input credit by ginning companies.

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...

A Typology for Vulnerability and Agriculture in Sub-Saharan Africa AgEcon
Zhang, Xiaobo; Rockmore, Marc; Chamberlin, Jordan.
This paper considers vulnerability reduction in Sub-Saharan Africa (SSA) from a more aggregated macro viewpoint. We focus on risk related to agriculture, since vulnerability and agriculture are intimately linked in SSA due to the location of the poor, their dependence on agriculture and the inherent risks of an agricultural livelihood. We argue that agricultural growth is one of the most effective means for improving permanent incomes and reducing vulnerability. However, agriculture is not homogeneous, and the inherent risks vary across countries and regions. Therefore, we also discuss appropriate investment strategies and policy instruments for different sets of risks.

A Value Chain Task Force Approach for Managing Private-Public Partnerships: Zamiba’s Task Force on Acceleration of Cassava Utilization. AgEcon
Chitundu, Maureen; Droppelmann, Klaus; Haggblade, Steven.
Smallholder farmers operate in vertical supply chains. Therefore, an understanding of key opportunities and constraints up through the value chain becomes necessary for sustaining smallholder growth. Yet market analysis is of little value unless key private and public sector stakeholders agree to implement necessary reforms. This paper advocates an approach which marries together value chain analysis with a stakeholder taskforce to ensure that analysis of opportunities and constraints gets translated into actions that will facilitate commercial growth. Using Zambia’s cassava task force as an example, the paper describes the value chain task force method and identifies elements critical to its effective implementation.

Accelerating Growth and Structural Transformation: Ghana’s Options for Reaching Middle-Income Country Status AgEcon
Breisinger, Clemens; Diao, Xinshen; Thurlow, James; Yu, Bingxin; Kolavalli, Shashidhara.
Ghana is an emerging success story in Africa and in a couple of years will become the first African country to achieve the first Millennium Development Goal of halving its national poverty rate. The government of Ghana has therefore extended its development vision and recently declared the goal of reaching middle-income-country (MIC) status by 2015. To analyze possible pathways and implications of achieving MIC status, this paper examines other countries’ experiences on their way to becoming MICs and emphasizes the important role of growth acceleration, export diversification, and economic structural change in the transformation process. The paper further analyzes Ghana’s growth options and their structural implications using a dynamic computable general...

AFRICA GROWTH AND OPPORTUNITY ACT (AGOA) AND AFRICAN AGRICULTURE AgEcon
Akanji, O.O..
AGOA directs the President of the United States to convene an annual meeting between the U.S. government and representatives of eligible African countries and to prepare an annual report to Congress on U.S. trade and investment policies with sub-Saharan Africa (SSA). Currently, Angola, Gabon, Nigeria and South Africa- accounted for the bulk (84 percent) of U.S. total imports from SSA. Since the passage of AGOA, the business climate has improved for non-agricultural exports and growth in these sectors has made relatively low direct benefits to Africa’s poor. Consequently, expanding AGOA’s application to African agriculture would have a significant impact on reducing hunger and poverty and therefore, on improving overall conditions in SSA. As a result of...

African Aquaculture: A Regional Summary with Emphasis on Sub-Saharan Africa OceanDocs
Moehl, J.; Machena, C..
The African Region consists of 48 countries and five island nations, most of which are practising some form of aquaculture, often at a very low level. Over half the countries report producing less than 100 mt annually. The largest producer is Nigeria (17 700 mt) followed by Madagascar (5 100 mt) and Zambia (4 700 mt). The 1997 combined aquaculture production of the region was 40 300 mt. Aquaculture is estimated to be 95 percent small scale, with fish ponds integrated into the mosaic of agricultural activities. Mean yield is approximated as 500 kg/ha/yr, although the range is wide, from less than a hundred to more than 10 000 kg/ha/yr. A typical scenario would be a 300 m2 pond producing 15 kg a year relying on family labour and on-farm inputs. There is...

African hunt for investment: any chance for success? AgEcon
Dyakov, Ignaty.
During recent two decades the world has witnessed a drastic increase in global FDI inflows. Gradually more and more investment has been directed to the developing countries in the attempt to diversify portfolios and use finance in the most efficient way. Not all developing regions of the world perfectly succeeded in attracting FDI. Large by labor force and territory, abundant in natural resources Sub-Saharan Africa could perform much better in this aspect. This paper once again reviews the opportunities for FDI in Africa and suggests possible ways for authorities of African states to overcome the existing situation.

African Regional Integration: Implications for Food Security AgEcon
van Dijk, Michiel.
This report looks at the African regional trade, regional integration agreements (RIAs) and the implications for food security. An overview is presented on the present state of African regional integration and the determinants of regional trade in agriculture and food commodities. In particular the study focuses on eight target countries, related RIAs and a set of strategic food commodities. The evidence presented in this study shows that African countries have made progress in opening up agriculture and food trade with partner countries. With, the exception of Ghana, Tanzania and Mozambique, the effective applied tariff rates for regional trade partners are substantially lower than the (MFN) rates applied to world trade partners. Nonetheless, regional...
