Book Synopsis Modeling Land-use Change in the Volta Basin of Ghana by : Ademola K. Braimoh
Download or read book Modeling Land-use Change in the Volta Basin of Ghana written by Ademola K. Braimoh and published by Cuvillier Verlag. This book was released on 2004 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land change studies in a 5,400km2 area within the Volta Basin of Ghana were carried out using satellite image and socio-economic analyses. The dominant change process was conversion of natural vegetation to cropland at an annual rate of 5%. Reversible land change trajectories involving accumulation of woody biomass indicate a certain level of rainfall-induced ecosystem resilience. Linear and logistic regressions identified agricultural land suitability, distance from main market and localities, child-dependency ratio and population density as the main drivers of change. Policy measures that would relieve human pressure on vegetation resources, guarantee food supply and promote commercialization of agriculture are suggested.
Book Synopsis The Volta River Basin by : Timothy O. Williams
Download or read book The Volta River Basin written by Timothy O. Williams and published by Routledge. This book was released on 2016-09-19 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Climatic Change: Implications for the Hydrological Cycle and for Water Management by : Martin Beniston

This book was released on 2006-04-11 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: year simulations in order to separate noise in the system from the climate change signal. Several contributing papers focused on case studies using Regional Climate Models (RCMs) linked to hydrological models, applied to the analysis of runoff under conditions of convective activity and extreme precipitation, in regions of complex topography, or stakeholder-driven investigations such as water runoff simulations in Quebec undertaken for a major utility. Thorough analyses of GCM results for the Century were reported at the Workshop, in order to illustrate the improvements in model results which have taken place in recent years, and the increasing confidence with which the models can be used for projecting climatic change in coming decades. However, there is still much room for improvement; there is also a need to address more fully the manner in which climate and impacts models (e. g. , hydrological models) can be linked, in terms of consistency and the overlap between different scales, the underlying physical assumptions, and the parameterizations used. Session 2 was devoted to the two extremes of water resources, namely floods and droughts, the focus here being to identify the climate change component in river floods. These have significant economic implications, as was shown by several scientists from Western and Central Europe. Many long time series have been studied worldwide with the aim of detection of nonstationarities, yet there is no conclusive evidence of climate-related changes in flow records, in general.

Book Synopsis Impacts of Global Change on the Hydrological Cycle in West and Northwest Africa by : Peter Speth
Download or read book Impacts of Global Change on the Hydrological Cycle in West and Northwest Africa written by Peter Speth and published by Springer Science & Business Media. This book was released on 2010-08-12 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa is highly vulnerable to the impacts of climate change. In particular shortage of fresh water is expected to be the dominant water problem for West and Northwest Africa of the 21th century. In order to solve present and projected future problems concerning fresh water supply, a highly interdisciplinary approach is used in the book. Strategies are offered for a sustainable and future-oriented water management. Based on different scenarios, a range of management options is suggested with the aid of Information Systems and Spatial Decision Support Systems for two river catchments in Northwest and West Africa: the wadi Drâa in south-eastern Morocco and the Ouémé basin in Benin. The selected catchments are representative in the sense: "what can be learnt from these catchments for other similar catchments?

Book Synopsis Soil Characterization and Modeling of Spatial Distribution of Saturated Hydraulic Conductivity at Two Sites in the Volta Basin of Ghana by : Wilson Agyei Agyare
Download or read book Soil Characterization and Modeling of Spatial Distribution of Saturated Hydraulic Conductivity at Two Sites in the Volta Basin of Ghana written by Wilson Agyei Agyare and published by Cuvillier Verlag. This book was released on 2004 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the key parameters in hydrological and climate change modeling is a good estimation of the soil hydrauic properties in the region of interest. This study investigates the spatial distribution and variability of soil physical properties, with emphasis on saturated hydraulic conductivity at two pilot sites in the Volta Basin of Ghana. It focuses on the potential of pedotransfer functions (PTFs) and artificial neural network (ANN) approach for estimating saturated hydraulic conductivity. Saturated hydraulic conductivity was observed to be highly spatially variable; however, it can be estimated using selected PTFs and ANN for soils in the Volta Basin based on soil parameters that can readily be obtained from detailed soil maps--From cover.
Book Synopsis Surface Runoff and Infiltration Processes in the Volta Basin, West Africa by : Ayodele Ebenezer Ajayi
Download or read book Surface Runoff and Infiltration Processes in the Volta Basin, West Africa written by Ayodele Ebenezer Ajayi and published by Cuvillier Verlag. This book was released on 2004 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The study presents the analyses of field observations and simulation experiments with an event-based, two-dimensional hydrodynamic model. The model summarized the interactions between temporally dynamic rainfall, infiltration process and surface runoff in a catchment with varied soil physio-hydraulic properties, surface-roughtness, slope-lengths and vegetation structure. Both observation and simulation results indicate that the observation scale affects runoff coefficient and runoff discharge per unit area. The effect of scale is a result of spatial variability in infiltration opportunities, which vary with the slop length and distribution of saturated conductivity, leading to different trasmission losses potential during runoff routing downslope. The magnitude of the difference is influenced by surface and vegetated microtopography, which determine the flow rate"--Back cover.
Book Synopsis Management of Bombus Atratus Bumblebees to Pollinate Lulo (Solanum Quitoense L), a Native Fruit from the Andes of Colombia by : Maria Teresa Almanza Fandiño
Download or read book Management of Bombus Atratus Bumblebees to Pollinate Lulo (Solanum Quitoense L), a Native Fruit from the Andes of Colombia written by Maria Teresa Almanza Fandiño and published by Cuvillier Verlag. This book was released on 2007 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis The potential of oil palm and forest plantations for carbon sequestration on degraded land in Indonesia by : Syahrinudin
Download or read book The potential of oil palm and forest plantations for carbon sequestration on degraded land in Indonesia written by Syahrinudin and published by Cuvillier Verlag. This book was released on 2005 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Ecophysiological Diversity of Wild Arabica Coffee Populations in Ethiopia by : Taye Kufa Obso
Download or read book Ecophysiological Diversity of Wild Arabica Coffee Populations in Ethiopia written by Taye Kufa Obso and published by Cuvillier Verlag. This book was released on 2006 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
