Benjamin The Texture of Change: Cloth Commerce and History in West Africa, 1700-1850 Abstract This study re-examines historical change in western Africa during the eighteenth and nineteenth centuries through the lens of cotton textiles; that is by focusing on the production, exchange and consumption of cotton cloth, including the evolution of clothing practices, through which the region interacted with other parts of the world. It advances a recent scholarly emphasis to re-assert the centrality of African societies to the history of the early modern trade diasporas that shaped developments around the Atlantic Ocean.

To carry out this regional study, the Club du Sahel Secretariat and the CINERGIE group (a project set up under a 1991 agreement between the OECD and the African Development Bank) formed a multi-disciplinary team of African and non-African experts.

  • World Bank Document
    69972 Options for Preparing a Sustainable Land Management (SLM) Program in Mali Consistent with TerrAfrica for World Bank Engagement at the Country Level Introduction Public Disclosure Authorized 1. Background and rationale: 1. One of the most environmentally vulnerable areas of the world is the drylands of sub-Saharan Africa, particularly the Sahel, the Horn of Africa and Southeast Africa. Mali, as with other dryland areas in this category, suffers from droughts approximately every 30 years. These droughts triple the number of people exposed to severe water scarcity at least once in every generation, leading to major food and health crisis. In general, dryland populations lag far behind the rest of the world in human well-being and development indicators. Similarly, the average infant mortality rate for dryland developing countries exceeds that for non-dryland countries by 23% or more. The human causes of degradation1 and desertification2 include direct factors such as land use (agricultural expansion in marginal areas, deforestation, overgrazing) and indirect factors (policy failures, population pressure, land tenure). The biophysical impacts of dessertification are regional and global climate change, impairment of carbon sequestation capacity, dust storms, siltation into rivers, downstream flooding, erosion gullies and dune formation. The social impacts are devestating- increasing poverty, decreased agricultural and silvicultural production and sometimes Public Disclosure Authorized malnutrition and/or death. 2. There are clear links between land degradation and poverty. Poverty is both a cause and an effect of land degradation. Poverty drives populations to exploit their environment unsustainably because of limited resources, poorly defined property rights and limited access to credit, which prevents them from investing resources into environmental management.

While the western branch of the Diakhanke in Senegambia and Guinea has received much attention from researchers2, the southern branch of mori lineages with their imamates extending from Dia/Djenne up the river Bani and its branches have been almost ignored. It has established centres of learning along the major southern trade routes and in the Sassandra- Bandama-Comoë-Volta river basins up to the Akan frontier3. The Kamaghate imamate has been established with the Gonja in the Volta basin but can be traced back to the Jula/Soninke of Begho, Kong, Samatiguila, Odienne and ultimately to the region of Djenne and Dia.

  • Focuses on Sustainable Agriculture, Aquaculture and Forestry. Target 7
    AICHI BIODIVERSITY TARGET 7: SUSTAINABLE AGRICULTURE, AQUACULTURE AND FORESTRY ABT 7 – sustainable resource management – focuses on sustainable agriculture, aquaculture and forestry. Irrational and unsustainable utilization of resources constitute a great challenge to the attainment of both the ABT 7 and the goals set by the United Nations (SDGs). Thus, the Gambia cannot stand out of this regard despite the rate of biodiversity erosion triggered by unsustainable practices bound to agriculture, and forestry. These practices are observed as major factors that weaken the national efforts to conserve the integrity of the whole constituents of ecosystems which consequently requires a paradigm shift. Otherwise, there is a need to ponder over sustainable transition that can concomitantly guarantee the sustainable management of 50% of areas under agriculture, aquaculture and forestry and preserve biodiversity. In response to this ambition, the government did not contempt to a mere enforcement of environmental laws and regulations but further attempted to formulate realistic and integrated policies and programs such as Program for Accelerated Grow and Employment (PAGE), The Vision 2020 which promote development through sustainable management of natural resources. Target 7: by 2020, 50% of areas under agriculture, aquaculture, and forestry are managed sustainably, ensuring conservation of biodiversity Achieving ABT 7: key challenges The Gambia is one of the most challenged countries in West Africa in terms of biodiversity conservation based on a

Abstract Loganiaceae belongs to the Order Gentianales which consists of the families Apocynaceae, Gelsemiaceae, Loganiaceae, Gentianaceae and Rubiaceae. Several Herbaria samples were studied prior to collection from Forest Reserves and National Parks in Nigeria, Republic of Benin and Ghana – with the aid of collection bags, cutlass, secateurs and ropes. Plants parts, both vegetative and reproductive were assessed with the aid of meter rule and tape rule in their natural environment and in the laboratory. Strychnos species collected were 47 individuals; 35 species were adequately identified. Anthocleista genus consists of nine species, Mostuea - three species while Nuxia, Spigelia and Usteria were monotypic genera. The leaf surfaces within the family are: hirsute, pilose, pubescent, tomentose and glabrous as found in Mostuea hirsuta, Strychnos phaeotricha, Strychnos innocua, Strychnos spinosa and members of Anthocleista species respectively. Morphological characters show 10 clusters at threshold of 47 % similarity.

In this study, antidiabe- tic activity of root extract of Detarium microcapum was investigated in rat model of diabetes. A methanol root extract was prepared by soxhlet extraction and was separated into fraction using chloroform, n-hexane and methanol to yield chlorof- orm fraction (CF), n-hexane fraction (HF) and methanol fraction (MF). The extract and its fractions were screened for phytochemicals using standard methods. The acute toxicity (LD ) of the extract was determined in mice. Diabetes was induced 50 by a single ip injection of 120 mg/kg of alloxan monohydrate and glucose level was analyzed as indices of diabetes. The acute toxicity test showed that the root bark extract was safe at doses of up to 5 g/kg. The phytochemical screening of the plant revealed the presence of proteins, carbohydrates and terpenoids in large amount while saponins, resins, glycosides and flavonoids were present in moderate amount. The results indicated that intraperitoneal injection of ME, MF, CF and HF reversed the effect of alloxan in rats by different degrees.
