This book was released on 1985 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical paper presents three case studies of inland fisheries in the context of a multiple-use of land and water resources in the humid tropics of Asia. Two of the three river basins are situated on islands, i.e. the Agno in the Philippines and the Mahaweli in Sri Lanka; one is on mainland Asia, i.e. the Nam Pong Basin in Thailand. Although the river basins have a number of features in common, such as, for example, their size, forest cover and population density, they differ in a number of other environmental aspects and changes induced by the development taking place in their basins. Inland fisheries in all three catchments is represented both by capture and culture components with reservoir fisheries gaining in importance. The studies have shown that while the major constraint to the riverine fisheries has been identified as being the high level of transported sediments originating from eroding lands and mine waste discharge (the Agno Basin), in the reservoirs of Nam Pong and Mahaweli basins it has been the high fishing pressure, in one case non-regulated (Nam Pong), which has caused deterioration of fish stocks. Another constraint in force until recently was of a social (religious) character (Mahaweli Basin). The three studies have shown that in most situations inland fisheries can successfully develop under conditions of the multiple use of the resource.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the structure and nature of movements within the Earth's crust has become increasingly important as we try to understand the history of the Earth and try to use this knowledge as a key to events in the future. This is especially relevant to those everincreasing communities populating the edges of the Pacific Ocean. This collection of papers deals with the tectonic modelling and evolution in some of the most seismically active regions in the world. Structural and stratigraphical analysis, together with geophysical, petrological and geochemical data give us some insight into tectonic events from the past and how they affected ancient landforms, and gives us a clearer understanding of earth movements and, therefore, allows us to predict catastrophic events such as earthquakes with greater accuracy.
