Sri Lanka Environmental Issues

Sri Lanka’s Environmental Issues and Problems

The Sri Lanka National Report to the WSSD (2002) identified a number of critical environmental problems and issues. The following were the chief among them;

  • Deforestation caused by shifting cultivation, timber exploitation, fuel wood collection, encroachment of agriculture on forests;
  • Costal erosion, and resulting damage to beaches, coastal conservations and communities.
  • Soil erosion and loss of agricultural productivity of the land;
  • Pollution of water bodies, coastal eco systems and beaches caused by the discharge of industrial pollutants and raw sewage;
  • (Protected) sea level rise, landslides floods and other natural disasters, the victims of which are predominantly from the poorest segments of society, who are compelled to take the risk of occupying vulnerable areas;
  • Situation of reservoirs built for irrigation and /or hydro power generation purposes;
  • Poor natural resource management and land use patterns, resulting in the marginalization of lands, loss of productivity and depletion of non –renewable resources;
  • Atmospheric pollution from vehicle emissions and industries;
  • Urban expansion without concomitant infrastructural growth, resulting in the proliferation of slums and shanties, and many other urban problems.
  • Sri Lanka is an island, 65,610 km2 in area situated close to the Southeast corner of the peninsula of India. Despite its relatively small size, Sri Lanka possesses a high level of bioddiversity.

    Abstract
    Shrimp exports are one of Sri Lanka's major foreign exchange earners and account for 40%–50% of total aquaculture exports. There has been a recent and rapid expansion of the industry in the Northwestern Province (NWP) of Sri Lanka but the industry has suffered from disease outbreaks and environmental problems. Currently, shrimp farms cover nearly 3000 ha of the coastal area of the NWP.
    The environmental impacts of shrimp cultivation in general are well known and numerous research studies have been done. However, little work has been carried out in Sri Lanka. This study provides some necessary background to brackish water shrimp aquaculture in Sri Lanka. It focuses briefly on the development of shrimp aquaculture and the current status of the industry. Emphasis is placed on two broader aspects—impacts on the existing wetland ecosystem and on the environment. These impacts are presumed to be the main causes hindering the growth of the industry and raising widespread public protest. Current ecosystem and environmental management practices are discussed. Finally, strategic issues for management and sustainable growth are discussed.
