Asian-driven Resource Booms in Africa: Rethinking the Impacts on Development AgEcon
Breisinger, Clemens; Thurlow, James.
Today’s resource boom in Africa, driven by Asian economic growth, offers new opportunities for resource-rich African countries. Contrary to the experience of previous booms, however, most mining profits now accrue to foreign companies, leaving little room for governments to use revenues for pro-poor investments or to mitigate adverse distributional impacts. Taking Zambia as a case study, this paper shows that despite privatization, Dutch disease remains a valid concern and may hamper economic diversification, worsen income distribution, and undermine poverty reduction strategies. Mining royalties must, therefore, be increased and used to finance growth-inducing investments that encourage pro-poor economic diversification, else many African countries will...

Improving Food Security in Africa: Highlights of 25 Years of Research, Capacity-Building, and Outreach. AgEcon
Food Security Group at Michigan State University.
Decades of research have led to substantially improved understanding of the nature of food insecurity. A combination of economic growth and targeted programs resulted in a steady fall (until the food crisis of 2007/08) in the percentage of the world’s population suffering from undernutrition (from 20% in 1990/92 to 16% in 2006). Yet over a billion people still face both chronic and/or transitory food insecurity due to long-standing problems of inadequate income, low-productivity in agricultural production and marketing, and related problems of poor health and absence of clean water. Assuring adequate food security for such a large share of the world’s population is increasingly challenging due to continuing resource degradation driven by a combination of...

Effects of Trade Openness on Economic Growth: The Case of African Countries AgEcon
Yeboah, Osei-Agyeman; Naanwaab, Cephas B.; Saleem, Shaik; Akuffo, Akua S..
The relationship between trade and productivity has not been established theoretically. Some researchers have indeed found some, if not complete, support for the view that increasing openness has a positive impact on productivity. This study used a Cobb-Douglas production function as in Miller and Upadhyay (2000) to estimate the impact of FDI, exchange rate, capital-labor ratio and trade openness on GDP for 38 African countries from 1980 to 2008. Data were transformed to natural logs and estimated using alternative panel models; which included one- or-two-way fixed or random effects models. The results found trade openness having a positive relationship with GDP; which is comparable to findings of Ahmed et al.; (2008).

THE ROAD TO PRO-POOR GROWTH IN ZAMBIA: PAST LESSONS AND FUTURE CHALLENGES AgEcon
Thurlow, James; Wobst, Peter.
Zambia is one of the poorest countries in Sub-Saharan Africa. Almost three-quarters of the population were considered poor at the start of the 1990s, with a vast majority of these people concentrated in rural and remote areas. This extreme poverty arose in spite of Zambia’s seemingly promising prospects following independence. To better understand the failure of growth and poverty-reduction this paper first considers the relationship between the structure of growth and Zambia’s evolving political economy. A strong urban-bias has shaped the country’s growth path leading to a economy both artificially and unsustainably distorted in favor of manufacturing and mining at the expense of rural areas. For agriculture it was the maize-bias of public policies that...

The Impact of Life Expectancy in Human Capital Accumulation: AIDS AgEcon
Huang, Rui; Fulginiti, Lilyan E.; Peterson, E. Wesley F..
A three period overlapping generations model is developed to investigate the impact of shorter life expectancy due to disease, on human capital investment decisions and income growth. This research is particularly relevant to Sub-Saharan Africa given the dramatic reduction in life expectancy due to HIV/AIDS and the potential lasting effects on growth. Our results indicate that as life expectancy shortens so does schooling inducing a lower growth rate of income. These relationships are even more pronounced for the African continent than for the rest of the world.

Climate change impacts on hydrology and water resources of the Upper Blue Nile River Basin, Ethiopia AgEcon
Kim, Ungtae; Kaluarachchi, Jagath J.; Smakhtin, Vladimir U..
The report evaluates the impacts of climate change on the hydrological regime and water resources of the Blue Nile River Basin in Ethiopia. It starts from the construction of the climate change scenarios based on the outcomes of several general circulation models (GCMs), uses a simple hydrological model to convert theses scenarios into runoff, and examines the impacts by means of a set of indices. The results, however uncertain with existing accuracy of climate models, suggest that the region is likely to have the future potential to produce hydropower, increase flow duration, and increase water storage capacity without affecting outflows to the riparian countries in the 2050s.

Commercial Dynamics in Zambia’s Cassava Value Chain AgEcon
Haggblade, Steven; Nyembe, Misheck.
Cassava production has grown rapidly in Zambia since the early 1990’s. Available evidence suggests that volumes of traded cassava have been increasing roughly twice as fast as production. Yet this cassava production boom could stall unless commercial markets for it develop. To help accelerate commercial development of cassava and cassava-based products at the national level, Zambia’s Agricultural Consultative Forum (ACF) initiated an Acceleration of Cassava Utilization (ACU) Task Force, beginning in August 2005. At a regional level, efforts such as the Cassava Transformation in Southern Africa (CATISA) project aim to complement national efforts and help facilitate regional spillovers, so that new products, new technologies or new lessons can help to...

HIV/AIDS and Agrarian Livelihoods in Zambia: A Test of the New Variant Famine Hypothesis AgEcon
Mason, Nicole M.; Chapoto, Antony; Jayne, Thomas S.; Myers, Robert J..
Since the southern African food crisis of 2001/02, the ‘new-variant famine’ (NVF) hypothesis first proposed by de Waal and Whiteside (2003) has become an important part of the conventional wisdom surrounding the relationship between HIV/AIDS and food crises in the region. The NVF hypothesis suggests that HIV/AIDS is eroding agrarian livelihoods and exacerbating the effects of drought and other shocks on agrarian communities. These concepts have begun to shape the HIV/AIDS mitigation and food security policies and programs of governments and development agencies. To date, however, there is a dearth of empirical evidence to support the NVF hypothesis, and there have been no studies specifically designed to tests its predictions.

Alert at Maradi: Preventing Food Crises in West Africa by Using Price Signals AgEcon
Araujo, Claudio; Araujo-Bonjean, Catherine; Brunelin, Stephanie.
The aim of this paper is to exploit grain price data to detect the warning signs of looming food crises in Mali, Burkina Faso and Niger. Firstly we identify which markets play a leading role at the national and regional level. The second step consists of identifying crisis periods and characterizing price movements during the period proceeding a crisis. This analysis leads to the identification of early warning indicators whose relevance is tested using panel data qualitative choice models. The results show that monitoring price movements on "leading markets" during crucial periods of the year can help in forecasting future crises.

An Assessment of the UN's Millennium Development Goals and its Millennium Declaration AgEcon
Tisdell, Clement A..
The United Nations’ Millennium Declaration, passed by the General Assembly in September 2000, is assessed with particular attention being given to the Millennium Development Goals and associated targets outlined in the Declaration. The focus of the article is not so much on the extent to which these goals are being met but on the adequacy of the Declaration itself. The fundamental values outlined in the Declaration are listed and assessed. The Millennium Development Goals are means for the attainment of these values, along with some other objectives specified in the Declaration. Both sets of objectives are examined, with most attention being given to the Millennium Development Goals and Targets. The Millennium Development Goals aim to reduce social and...

Biting the Bullet : How to Secure Access to Drylands Resources for Multiple Users AgEcon
Mwangi, Esther; Dohrn, Stephan.
Close to one billion people worldwide depend directly upon the drylands for their livelihoods. Because of their climatic conditions and political and economic marginalization drylands also have some of the highest incidents of poverty. Pastoral and sedentary production systems coexist in these areas and both very often use common property arrangements to manage access and use of natural resources. Despite their history of complementary interactions, pastoralists and sedentary farmers are increasingly faced with conflicting claims over land and other natural resources. Past policy interventions and existing regulatory frameworks have not been able to offer lasting solutions to the problems related to land tenure and resource access; problems between the...

Pathways to Improved Profitability and Sustainability of Cotton Cultivation at Farm Level in Africa: an Approach to Addressing Critical Knowledge Gaps AgEcon
Kelly, Valerie A.; Boughton, Duncan; Magen, Benjamin B..
In 2009, the World Bank published a comparative study of cotton sector reforms, based on detailed case studies carried out during 2007/08 in nine of Africa’s main cotton producing countries. The purpose of the study was to draw practical insights from the diversity of experiences in institutional reforms of cotton sectors and to better understand the strengths and weaknesses of the different types of sectors operating in Africa, the likely effects of specific types of policy change, and the possible ways forward. This paper develops a concept note for additional research that would address the perceived weaknesses of the earlier work. The underlying hypothesis of the proposed study is that technology research, farmer training, and policy and institutional...

Trends in Agricultural and Rural Development Indicators in Zambia. AgEcon
Jayne, Thomas S.; Govereh, Jones; Chilonda, Pius; Mason, Nicole M.; Chapoto, Antony; Haantuba, Hyde H..
Effective agricultural and food security policies in Africa need to be based on a solid empirical foundation. In Zambia, it is widely perceived that poverty rates are increasing, agricultural growth is stagnant, and real food prices are higher as food production declines. This study examines these trends and finds that all of these perceptions are wrong. Rural poverty rates have declined substantially in rural Zambia since the early 1990s, although they are still unacceptably high. Real staple food prices for consumers have declined by 20% over the past decade, thanks to major reductions in maize milling and retailing margins. And there is evidence of impressive production growth for some crops that are becoming increasingly important sources of income and...

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...
