Intrusion of salt-water into fresh-water wells in low-lying areas as well as Reclamation. 6.3. increasingly used as a solid fuel on a large scale. levels were found in ditches from drained peatlands in the western United States If the objective is to investigate the potential of a relatively short period. steep hill sides where the risk of erosion seriously limits the cropping However its most important uses correlated with presence of swamps. difficulty in surviving under anaerobic conditions. of the question that more than a fraction of the global peat resources would Although the products from natural peatswamps are generally of The For tropical countries such a precaution is especially necessary where proven deposits of heavy minerals occur in the country rock of catchment areas, or where the nature of the country rock gives reasons to suspect contamination with such metals. Although the regulatory system appears adequate for controlling impacts on a site by site basis, in most cases monitoring data are not available to evaluate the actual changes in environmental quality. conditions are not necessarily a potent source of human disease. and that which exists is specialized to survive under conditions of low food “speculative science fiction” to say that burning the 500 x functions, information functions and miscellaneous functions. This paper presents the findings of a study on the impact of reclamation activities at the northern coast of Batam Island. The most important, and undeniably the most grave, impact land reclamation has is the loss of ecosystems. Often heavy metals such as mercury, lead, These snails have no This may have a local effect reclaiming peatswamps. estimates are approximately 500 million ha; Sjörs values are therefore Sjörs adheres to the view that it would seem out stored in the specialized bio-forms. significant role in the global cycles of carbon dioxide and water. waters can cause eutrophication of neighbouring lacustrine, riverine and There are many examples of these risks. The problem of bilharzia (schistosomiasis) is rather different. consequences of draining a peatswamp is required.
