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.

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.

Book Description
Plant biomass represents a sink for atmospheric carbon dioxide, which is one of the most important greenhouse gases and which is assumed to contribute more than half of the global warming. Establishing tree plantations or perennial crops on degraded land is an effective way to reduce atmospheric carbon by building up terrestrial carbon stocks, not only in the living biomass, but also in the soil. By converting Imperata cylindrica grassland into tree plantations (Acacia mangium or oil palm), aboveground biomass carbon can be increased about 20-fold and below ground biomass carbon up to 8-fold, while soil carbon can almost be doubled.

Book Description
Soils of irrigated lands in the Aral Sea Basin are often plagued by high salinity,hampering profitable agriculture on these soils. In this context, the present study has three specific objectives: to identify techniques that enable a rapid estimation of soil salinity, to characterize its spatial distribution and to estimate its spatial distribution based on readily obtainable environmental parametersusing a Neural Network Model Approach. Topsoil salinity was highly variable atshort distances and terrain attributes were the most influential factors. The use of relationships between environmental attributes and soil salinity for upscaling spatial distribution of soil salinity from farm to district level proved to be satisfactory. A possible application is the development of salinity prediction toolsfor farm-level decision making.
