Coastal Impacts of Water Abstraction and Impoundment in Africa: the Case of Rufiji River
Provedor de dados: 20
Autores: Shaghude, Y.W.
Construction of large dams with reservoir type storage impound water behind them for seasonal annual, and in some cases for multi-annual storage and regulation of a river. Similarly, tubewells abstract surface and ground water bodies from their natural flow. The impoundment of water by damming and its abstraction through tubewells are common practices in the world and even within the Africa region (WCD, 2000). Globally, the number of large dams has grown at a tremendous pace during the last 50 years (Fig. 1.1) The fast growth in dam construction is driven by an increasing demand of water from urban and rural communities for reliable freshwater supply, agricultural irrigation and hydro-electric power. As these practices become more widespread, they are...

Composición y abundancia del meiobentos en el sublitoral de la  Habana, Cuba
Provedor de dados: 20
Autores: Armenteros Almanza, M.
En las regiones tropicales se han realizado estudios extensos sobre grupos  conspicuos como peces, corales y macroalgas, pero existe poca información  comparativa sobre la meiofauna (Gourbault et al., 1995). En Cuba se han publicado  varios trabajos sobre abundancia y distribución del meiobentos (Herrera y Del Valle,  1980; Herrera y Sánchez, 1982; Jiménez Ibarzábal, 1982; Herrera, 1983; Herrera y  Amador, 1983; Lalana-Rueda y Gosselck, 1986; López-Cánovas, 1987), pero en la  década pasada la ausencia de estos es notable.  En el sublitoral de La Habana se han realizado estudios de varias taxocenosis  correspondientes a la megafauna (ejemplos: peces, corales y gorgonias); la  complementación de tales estudios y el impacto que se  ejerce sobre esta zona...

Guidelines for the Study of Shoreline Change in the Western Indian Ocean Region
Provedor de dados: 20
Autores: Nyandwi, N.; Kairu, K.
This manual sets out an approach to the identification and monitoring of shoreline change and its causative processes at local and regional scales that is appropriate to the coastal management problems of the region as reported by the regional contributors. The approach aims to promote the targeting of sparse resources on the acquisition and provision of information that is most relevant to the management of the problem. The procedures for monitoring shoreline change and its contributory processes are described, including the use of accessible relevant regional information and data or meta-data sets.
