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...

The Contribution of Non-Timber Forest Products to Rural Household Income in Zambia AgEcon
Mulenga, Brian P.; Richardson, Robert B.; Mapemba, Lawrence D.; Tembo, Gelson.
Forest products play an important role in supporting rural livelihoods and food security in many developing countries. Pimentel et al. (1997) found that the integrity of forests is vital to world food security, mostly because of the dependence of the poor on forest resources. Studies of the role of forest products in household welfare in Zambia have found that such products are among the top sources of household income in some rural areas. This paper uses statistical analysis to examine the role of non-timber forest products NTFPs) in rural household welfare in Zambia, with two main objectives. First, using rural household survey data, we estimate the share of NTFP income to total household income with the aim of assessing the proportion and distribution...

Trends in Maize Grain, Roller and Breakfast Meal Prices In Zambia AgEcon
Kuteya, Auckland N.; Jayne, Thomas S..
1. Compared to the general price of goods and services as measured by the consumer price index, the prices of retail roller and breakfast maize meal have declined by between 34 and 51% in the major urban markets of Zambia between 1994 and 2010. 2. Inflation-adjusted wholesale maize grain prices have also declined over this period but by a smaller amount. 3. Inflation-adjusted marketing margins between the wholesale price of maize grain and the retail prices of roller and breakfast meal have declined from 41% to 64% since the early 1990s when the market liberalization process began. Since the early 1990s, there has been substantial new investment in commercial maize milling as well as by the informal hammer milling industry. Enhanced competition at this...

Marketing Policy Options for Consumer Price Mitigation Actions in the 2008/09 Maize Marketing Season in Zambia. AgEcon
Chapoto, Antony; Haggblade, Steven; Shawa, Julius J.; Jayne, Thomas S.; Weber, Michael T..
1) Maize prices are rising rapidly in 2008 and are fast approaching import parity levels. 2) Maize traders, millers and farmers all agree that Zambia will likely require imports by early 2009 in order to avoid domestic maize supply shortages. 3) Official food balance sheets appear to have underestimated the demand for maize this year. They may also have slightly overestimated the size of the 2007/08 maize crop. Hence the slow government recognition of the need for maize imports. 4) As of late September 2008, neither the Government of Zambia (GRZ) nor the private sector have arranged to import maize from South Africa. Trade sources suggest informal imports from Tanzania are helping to relieve the likely shortfall. 5) Zambian policy makers face a delicate...

Adoption of Hybrid maize in Zambia: effects on gender roles, food consumption, and nutrition AgEcon
Kumar, Shubh K..
Enhanced agriculture productivity in sub-Saharan Africa is critical to promote economic growth and poverty alleviation and to avoid increasing food scarcities in the region. The impact of commercialization and intensification of agriculture on the well- being of the rural poor depends on how they are carried out. Past research by IFPRI and collaborating institutions on commercialization of small- scale farming in about a dozen countries provided new knowledge about the relationships between commercialization and rural well- being as measured by incomes, consumption, and nutrition. These links were shown to depend greatly on household behavior, which in turn is influenced by intrahousehold processes. A better understanding of these processes is likely to...

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.

Food Crises and Food Markets: Implications for Emergency Response in Southern Africa. AgEcon
Tschirley, David L.; Jayne, Thomas S..
Concern about humanitarian crises in southern Africa, especially in light of the surge in world food prices since 2007, has been accompanied by calls for direct government action in food markets. This paper reviews how Zambia, Malawi, and Mozambique handled private food markets during the food crises of 2001/02, 2002/03, and 2005/06, which may provide important lessons for the management of future crises. Lack of trust between government and traders can lead to behavior that undermines the interests of each and harms consumers and farmers; Malawi and Zambia have persistently fallen into this trap while Mozambique has partially avoided it. Empirical policy analysis can make an important contribution to resolution only within a consultative process involving...

Smallholder Income Diversification in Zambia: The Way Out of Poverty? AgEcon
Bigsten, Arne; Tengstam, Sven.
This paper investigates the relationship between income diversification and income change within Zambian smallholder households, and investigates what the constraints of income diversification are in this group. A panel data set of roughly 7000 smallholder farmer households interviewed in 2001 and 2004 is used. Different combinations of the four main income generating activities – farm income, agricultural wage work, non-agricultural wagework, and own-business income – are analyzed.

Promoting Fertilizer Use in Africa: Current Issues and Empirical Evidence from Malawi, Zambia, and Kenya AgEcon
Minde, Isaac J.; Jayne, Thomas S.; Crawford, Eric W.; Ariga, Joshua; Jones, Govereh.
It is generally agreed that increasing agricultural productivity is critical to stimulating the rate of economic growth in Africa. There are many important and often complementary determinants of agricultural productivity. In this brief and the full paper it draws from, the focus is on fertilizer and improved seed, without intending to imply that they are the only or most significant productivity determinants.

Do Brokers Help or Hinder the Marketing of Fresh Produce in Lusaka? Preliminary Insights from Research AgEcon
Tschirley, David L.; Hichaambwa, Munguzwe.
Brokers are agents who arrange sales without taking ownership of the commodity, earning their money on a commission. Brokers are a common but often controversial presence in wholesale markets of East and Southern Africa. Efficient brokering can be beneficial by matching buyers and sellers more effectively than if each had to search independently for someone to transact with. Yet buyers and sellers can be harmed if brokers are able to behave in uncompetitive, collusive, or unethical ways. In Soweto market of Lusaka, common complaints lodged by sellers are that brokers force sellers to use them by threatening the security of the sellers’ produce, and that the brokers add “hidden” commissions when selling a farmer or trader’s produce. This policy brief...

Development, Diffusion and Impact of Conservation Farming in Zambia AgEcon
Haggblade, Steven; Tembo, Gelson.
The study reported in this paper measures differences in profitability between conservation farming (CF) practices and conventional agriculture by comparing the value of differential output with the differential input costs. The main objective is to address and fill several important knowledge gaps by investigating three key features of conservation farming in Zambia: 1) the process by which CF originated and spread; 2) the scale of CF adoption across household groups and regions; and 3) the impact of CF on crop output, input use, cost of production and farm income.
