The Local Social and Environmental Impacts of Smallholder-Based Biofuel Investments in Zambia Ecology and Society
German, Laura; Center for International Forestry Research; L.GERMAN@cgiar.org; Schoneveld, George C.; Center for International Forestry Research; G.Schoneveld@cgiar.org; Gumbo, Davison; Center for International Forestry Research; D.Gumbo@cgiar.org.
High oil prices, recent commitments by industrialized countries to enhance the use of renewable energy, and efforts by developing countries to stimulate foreign investment as a pathway to development have fueled high levels of interest in the biofuel sector throughout much of sub-Saharan Africa. Zambia is no exception. A large, land-locked country with high pump prices and vast tracts of land considered by many to be “degraded” or “underutilized,” investor interest in the sector has remained high despite uncertainties associated with unproven feedstocks and market fluctuations. While investment in multiple feedstock and production models may be observed, one of the primary investments has been in jatropha outgrower...

Notes on Micractaeon, a monotypic genus of African land snails (Gastropoda Pulmonata: Ferussaciidae?) Naturalis
Bruggen, A.C. van; Winter, A.J. de.
Micractaeon kakamegaensis Verdcourt, 1993 (type loc. Kenya, Kakamega Forest), is a synonym of Pseudopeas koptawelilense Germain, 1934 (type loc. Kenya, Mt. Elgon); the proper name is therefore Micractaeon koptawelilensis (Germain, 1934). New anatomical data are supplied, more or less confirming classification in the family Ferussaciidae. The shell is subject to some considerable variation in size, shape and sculpture. The species appears to be widely distributed in various types of forest in tropical Africa (Ghana, Cameroon, eastern and south-eastern Zaïre, Kenya, Malawi, and eastern Zambia); hypsometrical distribution is generally from c. 950 m to c. 2300 m, although in Ghana it has been collected at altitudes of between < 250 and c. 700 m.

Geophila erythrocarpa (Rubiaceae), a new species from D.R.Congo and Zambia Naturalis
Dessein, S.; Vanthournout, S.; Niyongabo, F..
The species Geophila erythrocarpa (Rubiaceae) is described and illustrated. The new species is restricted to dry, dense forests of the Katanga province in D.R.Congo and the adjoining Copperbelt province in Zambia. The species is similar to and in the herbarium easily confused with G. obvallata from which it most clearly differs in having red instead of blue or black fruits. In flowering state, the two species can be separated by differences in calyx morphology. The new species shares the red-coloured fruits with G. afzelii, but differs from this species in the undivided stipules, the fewer-flowered inflorescences with smaller bracts, and details of the leaf coloration. The new species is further compared with all other Geophila species reported from Zambia...

A PCR-based survey of animal African trypanosomosis and selected piroplasm parasites of cattle and goats in Zambia OAK
Musinguzi, Simon Peter; Suganuma, Keisuke; Asada, Masahito; Laohasinnarong, Dusit; Sivakumar, Thillaiampalam; Yokoyama, Naoaki; Namangala, Boniface; Sugimoto, Chihiro; Suzuki, Yasuhiko; Xuan, Xuenan; Inoue, Noboru.
We screened cattle and goats from the districts of Chama, Monze and Mumbwa in Zambia for animal African trypanosomes, Babesia bigemina and Theileria parva using PCRs; 38.1% of the samples tested positive for at least one of the parasite species. The most common parasite was Trypanosoma vivax (19.8%). Its incidence was significantly higher in goats than in cattle, (P<0.05). B. bigemina was found in samples from all the three areas, making it the most widespread of the parasites in Zambia. Among the tested samples, 12.0% of the positive samples were mixed infections. There were significant differences in the infection rates of T. vivax (Mumbwa had a significantly higher infection rate [39.6%, P<0.0001]), Th. parva (Monze had the only cases...

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.

Raising the Productivity of Public Investments in Zambia’s Agricultural Sector. AgEcon
Govereh, Jones; Shawa, Julius J.; Malawo, Emma; Jayne, Thomas S..
Agriculture provides the main support for Zambia’s rural economy, and because of this, growth in the agricultural sector is the clearest avenue through which poverty reduction can be achieved in Zambia. Yet despite widespread recognition of the strong connection between agricultural development and poverty reduction, there is continuing under-provision of public goods investments for over a decade. Zambia’s primary policy objective of achieving accelerated growth and competitiveness in the agricultural sector cannot be achieved unless adequate public resources are committed towards catalyzing the desired growth. Strong evidence from southern Africa as well as throughout the world indicates that long–term public investment in research and development,...

Impact of Natural Resource Conservation Policies on Household Consumption Around Zambian National Parks AgEcon
Tembo, Gelson; Bandyopadhyay, Sushenjit; Pavy, Jean-Michel.
Key Policy Points - Game Management Areas (GMAs) in Zambia aim to combine nature conservation with economic empowerment of rural households and communities. - We find evidence of consumption gains from living in GMAs and from participating in natural resource management through Community-Resource Boards (CRBs) and Village Action Groups (VAGs). - However, these benefits are unevenly distributed. Only GMAs with limited alternative livelihoods (Bangweulu and South Luangwa) exhibit significant consumption benefits. Also, the benefits accrue mainly to the relatively well off while the poor do not gain even if they participate. - Resources from ZAWA to CRBs seldom reach the VAGs. Richer, more educated community members participate at CRB or higher level while...

Review of Sample Design for Zambia Post-harvest Survey (1997/98) and Recommendations for Improving the Sampling Strategy and Estimation Procedures AgEcon
Megill, David J..
Following a review of the sample design for the 1997/98 Zambia Post-Harvest Survey (PHS), described in the survey reports, summary results were tabulated from the survey data to examine the distribution of the households for the different domains of analysis such as farm size groups. Summary data were also examined for the different crops and animals. The purpose of this report is to document the findings and recommendations from this review. Specific recommendations are made on potential improvements to the sample design. This report also includes the results of the CENVAR analyses, and specifies the procedures for weighting the data and calculating the standard errors. A separate report on “Review of Questionnaire for Post-Harvest Survey...

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...

Monitoring of Public Spending in Agriculture in Southern Africa AgEcon
Chilonda, Pius; Olubode-Awosola, Femi; Minde, Isaac J.; Njiwa, Daniel; Govereh, Jones.
Public resources are limited and have competing demands, hence prioritization will be critical. Policymakers want to know what public spending on agriculture sector will have the largest impact on the poor and how the resources should be allocated among the different sub-sectors. This brief examines the SADC region’s progress toward meeting the commitments made by African Heads of State and Government in the 2003 Maputo Declaration on Agriculture and Food Security to allocate at least 10 percent of national budgetary resources to agricultural sectors. Further, to build understanding of the challenges and opportunities facing governments as they strive to meet this target, the results of case studies of public expenditures on agriculture in Malawi and...

Disrupting Demand for Commercial Seed: Input Subsidies in Malawi and Zambia AgEcon
Mason, Nicole M.; Ricker-Gilbert, Jacob.
Input subsidy programs that provide inorganic fertilizer and improved maize seed to small farmers below market rates are currently receiving a great deal of support as a sustainable strategy to foster an African Green Revolution. In recent years numerous countries in Sub-Saharan Africa (SSA) including Ghana, Kenya, Malawi, Mali, Senegal, Tanzania, and Zambia have implemented such programs at substantial cost to government and donor budgets. For example, in 2008 Malawi spent roughly 70% of the Ministry of Agriculture’s budget or just over 16% of the government’s total budget subsidizing fertilizer and seed. In Zambia between 2004 and 2011, an average of 40% of the government’s agricultural sector budget was devoted to fertilizer and maize seed subsidies...

Effects of Maize Marketing and Trade Policy on Price Unpredictability in Zambia AgEcon
Chapoto, Antony; Jayne, Thomas S..
As events in the 2008/09 season have amply demonstrated, instability in staple food market remains a major problem in Zambia. A rise in world food price levels and instability, which is projected to occur in the near future according to several international institutes, will make it all more important for developing countries to consider the strengths and weaknesses of alternative approaches for buffering their domestic food systems from potential high volatility in world markets. These findings suggest that promoting more “rules based” approaches to...

The 2011 Surplus in Smallholder Maize Production in Zambia: Drivers, Beneficiaries, & Implications for Agricultural & Poverty Reduction Policies AgEcon
Mason, Nicole M.; Burke, William J.; Shipekesa, Arthur M.; Jayne, Thomas S..
In 2011, Zambia recorded its second consecutive record-breaking maize harvest, and aggregate maize production levels in 2011 were more than double the average level from 2006 to 2008. The expansion in maize production over the period corresponds with the scaling up of the Government of the Republic of Zambia's (GRZ) two flagship agricultural sector programmes. These are: (i) maize purchases at pan-territorial, above-market prices through the Food Reserve Agency (FRA); and (ii) subsidized fertilizer distribution through the Fertilizer Support Programme and its successor, the Farmer Input Support Programme (FSP/FISP). More than 90% of GRZ funding for Poverty Reduction Programmes is devoted to the FRA and FSP/FISP, yet there has been no major reduction in...

Why Are Zambian Farmers Not Harvesting All Their Maize? AgEcon
Shipekesa, Arthur M.; Jayne, Thomas S..
1. According to nationally representative Crop Forecast Survey data, over the past 10 years farmers have harvested between 55 and 90 percent of the area that they planted to maize. 2. In the 2009/10 and 2010/11 crop years, over 80 percent of the maize area planted by small- and medium-scale farmers was harvested, mainly due to favorable weather. 3. In 2010/11, the ratio of harvested to planted maize area was highest in Luapula, Northern and Eastern (all over 90%), and lowest in Western (56%) and Southern Province (70%). 4. The main reasons provided by Zambian farmers for not harvesting all their area planted to maize are: (i) wilting due to drought (50.6%); (ii) crop failure due to lack of fertilizer (25.6%); and (iii) floods, heavy rains, and water...

An Assessment of Current Policy Initiatives in Zambia's Cotton Sector AgEcon
Zulu, Ballard; Tschirley, David L..
This paper assesses three of these policy initiatives: input credit provision for smallholder producers of selected cash crops including cotton, the proposed creation of a Cotton Board, and the emergence in 2003 of District Council levies as a point of conflict between local governments and cotton companies. The purpose of the paper is to provide guidance to public and private decision makers regarding key modifications which may need to be made to these policies to ensure continued healthy development of the sector.

Characteristics Associated with Prime-Age Mortality in Eastern and Southern Africa: Evidence from Zambia and Kenya AgEcon
Chapoto, Antony; Jayne, Thomas S.; Kirimi, Lilian; Kadiyala, Suneetha.
Campaigns to prevent the spread of HIV require accurate knowledge of the characteristics of those most likely to contract the disease. Studies conducted in Sub-Saharan Africa during the 1980s generally found a positive correlation between socioeconomic characteristics such as education, income, and wealth and subsequent contraction of HIV. As the disease has progressed, the relationship between socioeconomic status and HIV contraction may have changed, although there is little evidence to support this. An emerging strand of the literature on the AIDS epidemic in Africa posits that poverty is increasingly associated with the spread of the disease. However, this conclusion is somewhat contentious, as other recent studies find mixed evidence of a poverty-AIDS...

Mountains of Maize, Persistent Poverty AgEcon
Jayne, Thomas S.; Mason, Nicole M.; Burke, William J.; Shipekesa, Arthur M.; Chapoto, Antony; Kabaghe, Chance.
The past two years are a tribute to Zambian farmers; they have responded admirably to government efforts to promote maize production. But ironically, rural poverty remains stubbornly high despite the fact that the government has spent over 2% of the nation’s gross domestic product in supporting maize production and subsidizing inputs for farmers. Why is it that maize production has increased so impressively without making a serious dent in rural poverty? And what are the lessons for the new government?

Supply Response of Export Crops in Zambia: The Case of Coffee AgEcon
Mofya-Mukuka, Rhoda; Abdulai, Awudu.
1) Export diversification has long been at the centre of Zambia’s economic diversification policies. This article focuses on the coffee sector as a potentially important source of export diversification and examines its supply response to changes in various incentives. 2) Zambian coffee exhibits asymmetric short-run supply adjustments to long-run equilibrium such that production rises significantly after prices rise while changing little after prices fall. 3) The fact that coffee in Zambia is mainly grown for export, the changes in real exchange have the most significant effect on supply in that a depreciation in the Zambian Kwacha leads to an increase in coffee supply.
