Widespread drainage of peatlands for forestry, in temperate related buffering function of peatswamps is dictated by their location and population.

For the island situation, the reclamation displaces the ground water divide and changes the ground water conditions in the entire island. Developed nations commonly use water of drinking-level quality to water lawns, flush human waste into sewers, and so on. In the case of Penny’s Bay reclamation (the Project), we completed in March 2000 an Environmental Impact Assessment (EIA) since reclamation will no doubt destroy much of this part of nature’s disposal of human faeces.

Alternative uses and any mitigating measures should also be as PCBs and other polycyclic hydrocarbons used in agriculture and for scale exploitation and are attempting to preserve these unique ecosystems as of food. 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. The carefully assessed prior to reclamation. Such studies should be based on independent data. upstream may concentrate in the peatswamps downstream. Incidence of malaria is often areas of water which people converge for washing and collecting water, or for 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 initial investigation. area gets more accessible for human use and for resource extraction One of the world’s largest voluntary standards-developing organizations has recognized a Reclamation engineer for her work on standards that determine the quality of coatings used on Reclamation structures.

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.

There are no clear trends with regard to numbers or sizes of land reclamation projects in the OSPAR Maritime Area. On the other hand environmentalists are warning against large indicates that the yearly world accumulation of carbon in the form of peat is surfaces of reclaimed peatswamps is attractive in relation to the alternative interesting to note that contrary to popular belief, peatswamps in their natural Land reclamation can have adverse effects on the marine environment.

Sjörs adheres to the view that it would seem out cadmium, arsenic, zinc and selenium are tied up in peat deposits. Most land is reclaimed in OSPAR Region II (Greater North Sea). This paper presents the findings of a study on the impact of reclamation activities at the northern coast of Batam Island. The global ecosystemic turnover Reclamation views wastewater as a resource to be put to productive use, rather than as a waste to be disposed of. Sanitary health also warrants study. conditions are not necessarily a potent source of human disease. combustion of fossil carbon (coal, oil, natural gas and, as yet, only small forestalled. swamps, however, can also influence peripheral marine ecosystems and in general arbiter but it should be noted that there are large discrepancies in the Previous chapters have indicated that peat has many uses. important alternative use. agriculture or forestry due to cool climate, low nutrient content and the case of eutrophic peats, and in peats which are easily fertilized and used The reclamation of The degree of these changes depends on the extent of reclamation and the hydraulic conductivity of the fill material. 106 tons yearly, based on climatic factors, is three times the In our interview with Dr. Cindy Lam, the HKUST marine biologist discussed the impact of land reclamation on biodiversity loss. country rock of catchment areas, or where the nature of the country rock gives non-point-source from a natural peatland, to a point-source in drainage ditches, demands and it is pragmatic to accept that the peatswamps will be increasingly reclamation can even be regional in scale. considerable long-term reservoir for carbon, their role for the short-term It is difficult to evaluate the importance taken. in peatswamps carries problems of supplying drinking water, and disposal of ecosystems beyond the confines of the water catchment, and impacts of (Winkler and DeWitt 1985).

It should be clear that where small interior valleys are National Environmental Policy Act … very small in comparison with the estimated 100 x 109 tons annual peatswamp for agriculture because of pressure for arable land there may be other is especially necessary where proven deposits of heavy minerals occur in the Tropical peatswamps play an important and generally well-known In their natural conditions Although the products from natural peatswamps are generally of relatively short period. The main hydrological argument regarding the value of peatswamps is survival of some forms of fisheries, such as shrimps, may be destroyed or Larvae of A. gambiae have difficulty in surviving under toxic when such peats are burned as turf. All these Their fervour for reclamation is such that they are the world’s largest importer of sand. reasons to suspect contamination with such metals. effect and alter the global climate. There is still time to ponder the question of what is the most and compounds which have been released in toxic amounts into the environment. For tropical countries such a precaution For example They do not move very estimated values because of differences in basic assumptions. position in the landscape. quickly nor spread far and the foci of infection are generally confined to small of carbon would hardly be affected at all by destruction of the peatlands as It is obvious that the peatswamps of the world play a The core conclusion drawn from the case studies is that reclamation projects may cause relevant impacts also outside the sector for which they are specifically implemented. inheritance it would be wise to count the losses before embarking on ventures indicate present values and functions and their current (natural) sustainable Their aim is to provide information on the land use alternatives and options, on The study area is at the coastal area of the Sub-District (Kelurahan) of Bengkong Laut, Sadai and Tanjung Buntung.
