Book Description
The study assesses effects of population growth on agricultural land and forest in the Volta River Basin of Ghana. Most districts of the research area are experiencing shortfalls in land suitable for agriculture and deforestation. The number of farm holdings is decreasing and practice of fallow lands (last consequences of the former shifting cultivation) is also vanishing. Although households are wealthier due to new sources of off-farm income, the use of tractor, inorganic fertilizer and improved seed variety for farming is still low due to high costs. On deforestation, increases in fuel wood use and agricultural extensification are the major causes.

Ecophysiological Diversity of Wild Arabica Coffee Populations in Ethiopia
Author: Taye Kufa Obso
Publisher: Cuvillier Verlag
ISBN: 386727990X
Category :
Languages : en
Pages : 331
Book Description
Coffea arabica, one of the economically most important crops worldwide, occurs naturally in the undergrowth of montane rainforests of Ethiopia. The study provides the first detailed ecophysiological investigations of wild coffee populations. It demonstrates the inter- and intra-regional variability in phenotypic and hydrological characteristics of wild coffee. The results reveal very different strategies of wild coffee seedlings for coping with drought stress. The ecophysiological diversity shows the importance of Ethiopian wild coffee populations as gene pools for future breeding programs, and underlines the need for an in-situ conservation strategy. The study includes recommendations for coffee forest management and the use of wild arabica coffee in Ethiopia.

The Volta River Basin
Author: Timothy O. Williams
Publisher: Routledge
ISBN: 131747953X
Category : Nature
Languages : en
Pages : 376
Book Description
The Volta River Basin (VRB) is an important transboundary basin in West Africa that covers approximately 410,000 square kilometres across six countries: Benin, Burkina Faso, Côte d’Ivoire, Ghana, Mali and Togo. Its natural resources sustain the livelihoods of its population and contribute to economic development. This book provides a comprehensive, interdisciplinary review and assessment of the issues and challenges faced. The authors provide a science-based assessment of current and future scenarios of water availability, the demands of key sectors, including agriculture and hydropower, and the environment under changing demographic, economic, social and climatic conditions. They also identify solutions and strategies that will allow available water resources to be sustainably used to improve agricultural productivity, food security and economic growth in the VRB. Overall, the work examines from a multidisciplinary and multi-stakeholder perspective the solutions and strategies to improve the use of water and other natural resources in the VRB to achieve enhanced food security, livelihoods and economic growth.

Management of Bombus Atratus Bumblebees to Pollinate Lulo (Solanum Quitoense L), a Native Fruit from the Andes of Colombia
Author: Maria Teresa Almanza Fandiño
Publisher: Cuvillier Verlag
ISBN: 3867271879
Category :
Languages : en
Pages : 131
Book Description
Solanum quitoense (Lulo) from the northern Andes is a fruit with an attractive taste. It has a high export potential but its production is hampered by insufficient pollination. Studies on the reproductive system of Lulo revealed that, due to their poricidal anthers, the flowers need pollinators for self- and cross-pollination. Pollination by native bumblebees significantly increases fruit set and quality. Experiments show that colonies of Bombus atratus can be reared in captivity and used in Lulo fields for providing increased pollination services. Modeling based on data on colony development reveal larva/workers ratio and the supply of pollen as main parameters for improving the rearing method.
