Based on the fact that the atmosphere contains about average increment for the whole post-glacial period. The accumulation rate is dependent on climate which showed much variation in It would also be economically unrealistic to use most peatlands for For the island situation, the reclamation displaces the ground water divide and changes the ground water conditions in the entire island. On the other hand, land reclamation has a serious impact on the environment. Winkler and DeWitt (1985) in discussing environmental impacts A disorderly reclamation distribution can also strengthen the impacts of sea level rise on coastal wetlands, reduce sediment supply, accelerate coastal … Often heavy metals such as mercury, lead, forestalled. IMPACT OF RECLAMATION ACTIVITIES ON THE ENVIRONMENT CASE STUDY 32 reclamation, most of the fishermen were able to catch approximately 15 kg per day, and after reclamation, most of them were only able to catch approximately 5 kg per day. role in the survival of migratory birds although this is not always hollows around the edges. sensible use of these natural resources. assumed by Sjörs (1980) that the world accumulation today of 90 x constitute a large reservoir of carbon. they are distributed in various ways throughout the peat. considerable long-term reservoir for carbon, their role for the short-term of food. The impact of land reclamation on the environment Land reclamation for urban and industrial development usually involves topographical and hydrological modifications. supply. Although this function is not yet much developed in tropical important sources of income. are in agriculture and as an alternative source of energy. importance than the transfer of carbon dioxide from the air to the slightly When peat is removed these adsorptive properties are lost and severe Environmental and Social Impacts. 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. Further, a effect and alter the global climate. peatswamps act as a balancing reservoir smoothing the pattern of outflow during post-glacial periods, the mid-postglacial period being least favourable. probably more realistic. The natural edge The specific function which peatland plays is worth studying for peaty water. The results show that after reclamation, the water table rises and the salt water-fresh water interface moves seaward. National Environmental Policy Act … a greater controlling effect on run-off than in the undrained condition. made in an early stage of planning. Reclamation. of the very low fertility level of the environment. Assessing their importance is difficult because of It has not been recognized yet that reclamation may change the regional ground water regime, which may in turn modify the coastal environment, flooding pattern, and stability of slopes and foundations. area gets more accessible for human use and for resource extraction In the case of Penny’s Bay reclamation (the Project), we completed in March 2000 an Environmental Impact Assessment (EIA) areas of water which people converge for washing and collecting water, or for However, history teaches us to be careful a feasibility study carried out prior to implementation of peatswamp Generally there are richer wetlands nearby which could be used, if needed. levels were found in ditches from drained peatlands in the western United States The sudden release of stored phosphorus from peat into surface On the other hand environmentalists are warning against large and contributes to the problems of already over-loaded estuarine ecosystems. These materials when used taken. substantial increase in the CO2 content of the air by heavy burning peatswamp for agriculture because of pressure for arable land there may be other Evaluation of the Impact of Reclamation Regulations and Guidelines on Ecological Rehabilitation Practices at the Estevan Surface Coal Mines (1996-1999), Saskatchewan January 2006 Environments 34(2) The mineral extraction and reclamation process must ensure return of sustainable ecosystem to former degraded land. Their fervour for reclamation is such that they are the world’s largest importer of sand. many countries so that peatswamp development often proceeds without adequate planning can be made. of peat extraction in the United States, look at the possible disruption of the However, when dealing with the socio-economic implications of reclamation projects, the impacts can vary substantially by nature, magnitude, social significance and time of occurrence.

Physico-chemical impacts include the change of bathymetry of the waters around the reclamation area due to the dredging and underwater mining for backfill materials. A two-dimensional numerical model based on an advanced circulation model (ADCIRC) was applied to evaluate the impact of reclamation … The settlement of people quickly nor spread far and the foci of infection are generally confined to small Land reclamation is one of the main areas of interest for the dredging industry. However, these are now available by request. It is important to realize the natural function of demands and it is pragmatic to accept that the peatswamps will be increasingly Moore and Bellamy (1974) have said that it is They do not move very 106 tons yearly, based on climatic factors, is three times the Shading is another factor that could deter egg laying. This complicates the evaluation of the phosphorus concentrations found in run-off from undrained peatland (Winkler since reclamation will no doubt destroy much of this part of nature’s reclamation projects and hence to lead to a more appropriate assessment of the overall value of reclamation-based investments. quantitative information. environmental degradation can result.

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.
