Inland valleys are defined as the upper reaches of river systems. These include valley bottoms and minor floodplains,their hydromorphic fringes and upland slopes and crests. These occupy 22-52 million ha of land in W. Africa and although of good agricultural potential are only marginally used. An agro-ecological characterization developed in the Cte d'Ivoire, is outlined on 4 levels: macro (1:1 000 000-1:5 000 000), reconnaissance (1:100 000-1:250 000), semi-detailed (1:25 000-1:50 000) and detailed (1:5000-10 000).

L'étude sur l'harmonisation des politiques agricoles dans les Etats membres de l'Organisation du Bassin de la Rivière KAGERA répond donne a cette nécessité de fournir une information sur la situation de l'agriculture dans cette sous-région de l'OBK à toute la Communauté internationale (promoteurs/operateurs économiques, bailleurs de fonds bilatéraux et multilatéraux; institutions financières,...) pour lui permettre d'examiner le genre d'assistance et le volume d'intervention en faveur du développement du secteur agricole qui constitue une grande priorité des Etats de cette sous-région.

This note is divided into three sections. The first section describes the Final Act analyzing the details of the agreement on market access, domestic support, export subsidies, the special and differential treatment of the developing countries including the Decision referred to in (iii) above; and a brief look at other sectors.

A study was conducted of about 8000 ha around Timau area
in Meru District to evaluate its land suitability for
agriculture. A semi detailed soil survey was carried out to
classify and map the different soil units. Based on the
relevant land qualities of each Soil Unit and physiography
they were seperated in 15 Soil Mapping Units for the various
Land Utilization Types with land use recommendations given.
The following land qualities were rated and used to assess the
suitability of each Soil Mapping Unit: soil water retention,

The first four years of the 1990s indicate that African economies have grown by a mere 1.5 per cent per annum worse than during the "lost decade" of the 1980s when Africa's economic annual growth rate was on average 1.8 per cent during the period 1980-1990. This growth is barely half of the rate of growth of Africa's population and is well below the annual average growth target of 4 per cent set by the World Food Conference in 1974, and still worse than the 6 per cent set in the United Nations New Agenda for the Development of Africa in the 1990s.

The ideal water contract for a heterogeneous population of users is a prioritized right that is fully vested and fully tradable. A set of tradable, prioritized rights contracts will span the same space as the Debreu contingent commodities. Therefore, they lead to a competitive equilibrium that is Pareto optimal. Equal sharing of water shortfalls does not have this property.Existing water policies in Israel and the Disputed Territories are not characterized by an efficient set of water contracts.

This paper focuses on report of the workshop on grain marketing in transition Harare, Zimbabwe 11-17 October 1993. The purpose of the mission to Harare, Zimbabwe from 9-17 October 1993 was to service the Association of Food Marketing in Eastern and Southern African sub region workshop on "Grain Marketing in Transition".

The distributional benefits of commercialization of agriculture, access to commercialization opportunities, and sharing of commercialization risks are functions of institutional arrangements. Obviously, the indirect food security and nutritional effects are, thereby, partly a function of such institutional arrangements. This chapter explores the relevance to food security of one form of contractual relationship in agriculture: formal contracts between producers and buyers (generally processors or exporters), a production and marketing system known as contract farming.
