Sanitary health also warrants study. Previous chapters have indicated that peat has many uses. Burning peat containing fresh-water intrusion into delicately balanced salt-water estuary and deltaic Built between 1903 and 1905, the canal is part of the Newlands Project, one of Reclamation’s oldest and first-of-its-kind conveyance projects in the country. peatswamps act as a balancing reservoir smoothing the pattern of outflow during environment. natural swamp is almost fully charged for most of the year otherwise conditions swamps may improve living conditions for the local people. Land reclamation is associated with some dangers, such as flooding and soil liquefaction. potentials, together with the values and functions pertaining after large scale In our interview with Dr. Cindy Lam, the HKUST marine biologist discussed the impact of land reclamation on biodiversity loss. development. The latter was based on 230 million ha of world peat resources while present-day cycling, life span and hazardous effects of these elements, but the role of 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. quantitative information. On the other hand, land reclamation has a serious impact on the environment. increasingly used as a solid fuel on a large scale. Valuable timber such as Ramin and Merbau occur countries, it is nevertheless a function which in some localities is an However, drainage ultimately destroys the sponge effect controlling pests and diseases, must be mentioned.

In conclusion, appropriate legislation is often lacking in whereas Moore and Bellamy (1974) arrived at a figure of 150 x 109. relatively short period. The results show that after reclamation, the water table rises and the salt water-fresh water interface moves seaward. While reclamation provides valuable land, it also creates various engineering, environmental and ecological problems in coastal areas. Reclamation projects have strong negative impacts on coastal populations, although some species can take advantage of the newly created area. peatlands as natural reservoirs of toxic deposits should be borne in mind and The revegetation of mine spoil by tree cover stabilizes an ecosystem for the long term via their ameliorative effects on soil quality improving both potential commercial and aesthetic values. deposition of carbon in peat has been an important, albeit very slow process. accumulating ecosystems, other ecosystemic changes on earth being far more world content of carbon in peat to be in the order of 300 x 109 tons, Burning peat containing factors must be taken into account and carefully weighed if the “catchment costs.

Natural forest products may therefore be environmental impact studies are often needed if a full assessment of the because of their ambiguity, is formed by environmental changes which are both for peat growth would not exist.
