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... |

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. |

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... |

This research focuses on the performance in the Magoye ripper in maize and cotton production in Eastern and Southern Provinces during the 2004/2005 productions year. Findings include the following: In maize production, the ripper enabled higher yields compared to traditional animal ploughing, by increasing the effectiveness of nitrogen fertilizer applications, resulting in net profits per hectare of ZK575,800 in Eastern Province and ZK93,800 in Southern Province; In cotton, the input applications and size of fields were the most important determinants of yield, and the ripper had no significant individual effect. Farmers using the ripper indicated that it helped conserve water, enabled early land preparation and early planting; and Farmers not using their... |

The ability of agricultural policy makers to promote national development objectives requires an accurate and reasonably current picture of what crops farmers grow, what they eat, the importance of various crops in their incomes, and how they spend their money. In Zambia’s case, there is reasonably accurate information on production levels and trends in a specific set of crops grown by smallholder farmers, but very little knowledge of how important these specific crops are in smallholders’ total crop incomes, the importance of crop production in total smallholder incomes (which include livestock and non-farm activities), and how changes in crop prices affect smallholders’ welfare. This paper presents a comprehensive picture of crop production and marketing... |

The proportion of smallholder households selling horticultural produce is very low suggesting that new demand points could enjoy substantial supply response if they link effectively to the smallholder sector. The small-scale traditional marketing system continues to dominate fresh produce flows in the country. Prices for consumers in this system are much lower, and quality is comparable and sometimes superior to supermarkets. Yet these markets suffer from serious structural problems due to a lack of public investment and little collaboration between public officials and traders in market management. The Urban Markets Development Program represents a major and impressive effort to improve wholesale and retail markets in the country, but has run into... |

Cotton is one unquestioned success of Zambia’s turn towards a market economy. After liberalization in late 1994, production rose from 20,000 mt to over 100,000 mt in the 1998 harvest year. After collapsing to less than 50,000 mt in 2000, it has risen steadily, nearing 200,000 mt in 2005. Over 2002-2005, exports of cotton lint were first among all agricultural exports in value, 30% higher than any other agricultural export (Export Board of Zambia 2006). The closest competitor to cotton during this time –raw cane sugar –is primarily produced on large operations, while cotton is almost entirely a smallholder crop. Its potential role in poverty alleviation and food security is, thus, very large. The success of this sector has been achieved despite persistent... |

Rapid growth in urban populations and renewed growth in per capita incomes in Sub-Saharan Africa (SSA) are creating major opportunities for local farmers by driving rapid growth in domestic market demand for food. At the same time, these trends plus rising income are putting enormous stress on the supply chains that these farmers rely on to respond to this increasing demand: demand for marketed food is likely to grow more than 5% per year on the continent, doubling marketed volumes in 12-14 years. Currently, fresh produce marketing systems are the biggest users of public marketing infrastructure, and have been most severely affected by the lack of investment in these systems across much of the continent. This lack of investment has led to an exploding... |

Investment in agriculture is necessary for ensuring rapid economic growth and poverty reduction in Zambia, as elsewhere in Africa. Yet many of the key investments required to accelerate agricultural growth – technological research, rural infrastructure and market standards, organization and enforcement -- are public goods. Because the private sector cannot capture gains from these investments, they will not invest in amounts sufficient to ensure broad-based agricultural growth. Therefore, the public sector needs to provide the necessary research, transport and market infrastructure necessary to stimulate agricultural growth. Zambia currently allocates 6% of government outlays for agriculture. This is less that the 10% commitment Zambia has made under the... |

This policy synthesis highlights the key findings and conclusions contained in the full report, “Developments in Fertilizer Marketing in Zambia: Commercial Trading, Government Programs and the Smallholder Farmer.” The key objective of this policy synthesis is to summarize the key findings in order to inform policy makers and stakeholders in the agricultural sector in their efforts to improve the performance of the fertilizer marketing system in Zambia. |

The rapid recent appreciation of the Kwacha has placed these gains at risk. The sudden strengthening of the Kwacha since November 2005 has reduced the Kwacha value of agricultural exports by 30%, forcing reductions in farmgate prices and eroding exporter profit margins. As in a classic case of Dutch Disease, large inflows of foreign exchange–whether from surging international copper prices, foreign aid or speculative financial inflows–have contributed to the strengthening Kwacha. The subsequent rapid appreciation of the Kwacha risks making much of Zambia’s export agriculture uncompetitive on world markets. |

1. Changes in spinning technology have increased the premium on high quality lint in the world market and increased the discount for lint contaminated with non-vegetative matter 2. The inherent characteristics of most African lint, plus the fact that it is hand-picked, should give it a substantial premium in the world market. However, because so much African lint is highly contaminated by world standards, much of it trades at a discount to Index A. 3. Zambia has been the outstanding success among a sample of nine SSA countries in improving quality; this achievement is directly attributable to the efforts of Dunavant and Cargill, made possible by company culture and by the concentrated structure of Zambia's industry 4. Quality (and input supply) can be... |
