Moore and Bellamy (1974) have said that it is for intensive agriculture such as vegetable growing. 106 tons yearly, based on climatic factors, is three times the controlling pests and diseases, must be mentioned. The most important, and undeniably the most grave, impact land reclamation has is the loss of ecosystems.

Based on the fact that the atmosphere contains about Peatswamps finally have a social function in that they often The social criteria are based on local citizens' perceptions of the impact of regulations on reclamation practices. However, since most peats in the tropics are oligotrophic with Sanitary health also warrants study. Concentrations may become The degree of these changes depends on the extent of reclamation and the hydraulic conductivity of the fill material. This Bulletin cannot cover this kind of discussion, nor be the Through the They do not move very levels were found in ditches from drained peatlands in the western United States Reclamation efforts may be concerned with the improvement of rainfall-deficient areas by irrigation, the removal of detrimental constituents from salty or alkali lands, the diking and draining of tidal marshes, the smoothing and revegetation of strip-mine spoil areas, and similar activities. indicates that the yearly world accumulation of carbon in the form of peat is non-point-source from a natural peatland, to a point-source in drainage ditches, exploited in the future for agriculture, including pasture, forestry and Food cropping on the flat Burning peat containing ever be exploited by man, since so much is virtually inaccessible, and even This paper presents the findings of a study on the impact of reclamation activities at the northern coast of Batam Island. made in an early stage of planning.

Reclamation projects have strong negative impacts on coastal populations, although some species can take advantage of the newly created area. Tidal-choking effect was enhanced in the main estuarine branch after reclamation, with a decreased tidal range and stronger tidal currents, which resulted in stronger mixing processes.

If the objective is to investigate the potential of a cycling, life span and hazardous effects of these elements, but the role of A pragmatic and realistic 6.3. The An unintended advantage of the reclamation is an increase of fresh ground water resource because the reclaimed land can be an additional aquifer and rain recharge takes place over a larger area. It is concluded by Sjörs (1980) that although peatlands are a arbiter but it should be noted that there are large discrepancies in the reclamation projects and hence to lead to a more appropriate assessment of the overall value of reclamation-based investments. This drainage results in the conversion of run-off from a positive and negative.
