INTRODUCTION Sri Lanka is an island which often refers to as the pearl of Indian Ocean, located south east of India. Sri Lanka has a land area of 62710 km2 and approximately 1620 km long coastline including the shoreline of bay and inlets. For a small island like Sri Lank, coastal zone plays an important role in the country’s economy as well as landscape. While utilizing the coastal zone for the betterment of the country and the people, there are consequences to the environment and to the coastal ecosystems. The Island’s coastal zone provides significant contributions to the socio economic values connected to food security, public health, economic benefits and cultural values. Moreover, the coastal area provides many ecosystem services including…show more content…
According to the Intergovernmental Panel on Climate Change (IPCC) the excessive emission of greenhouse gases from unsustainable fossil fuel usage is the main cause of global warming and climate change. In fact the climate change will affect all countries in the world, particularly the impact on developing countries expected to be higher as they lack the necessary adaptive capacity. According to the Intergovernmental Panel on Climate Change (IPCC), the global mean surface temperature has increased 0.6 ± 0.2 oC since 1861, and predicts an increase of 2 to 4 oC over the next 100 years. In Sri Lanka temperature has increased by 0.640C over the past 40 years and 0.970C over the last 72 years, which revealed a trend of 0.140C per decade. However, the assessment of a more recent time band of 22 years has shown a 0.450C increase over the last 22 years, suggesting a rate of 0.20C increase each decade (Ministry of Environment of Sri Lanka,…show more content…
Sea level rise, temperature increase, coastal erosion, dying forests, increased weather anomalies, and natural disasters are some of the expected consequences of climate change that Sri Lanka will soon face and as mentioned above some of them are already experienced by Sri Lanka (Baba, 2010). Impacts of climate change in coastal area Sri Lanka is not an exception to get away from global warming and the adverse effects of climate change can be observed in coastal environment, agriculture, forest, biodiversity, health, energy and human settlements in the near future (Nilanthi, et al., 2006). Clearly the sea level rise will cost land in the coastal area which would put pressure on the increasing population and the industries that already established in the coastal zone. Moreover, flood risk and salinity in open bays will also increase as a result of slow freshwater flow to the sea. Also there some other negative impacts by the sea level rise such as inundation, shoreline erosion, coastal flooding, salinity of estuaries and aquifers, modify tidal range in rivers and bays and alter frequency and severity of storms (Nilanthi, et al., 2006). These impacts could lead to serious threads to the coastal ecosystems, coastal infrastructure and to human
