How has climate change affected the biodiversity of Chilka
Answers
Answer:
Lakes worldwide, including the Chilika Lake in India, are heating up quickly due to climate change, infers a recent study. The research, published in Geophysical Research Letters, is the largest global study on temperature changes of water surfaces in lakes in summer.
The 25-year-long study is the first to use a combination of satellite temperature data and long-term ground measurements for monitoring impact of climate change on lakes. A total of 235 lakes from six continents – Asia, Africa, Australia, North America, South America and Africa, representing more than half of the world’s freshwater supply, were monitored.
“Combining the ground and satellite measurements provides the most comprehensive view of how lake temperatures are changing around the world,” according to study’s co-author Simon Hook, science division manager at NASA’s Jet Propulsion Laboratory (JPL) in California.
Explanation:
Among hundreds of fresh and salt water lakes in India, Lake Chilika stands soaring due to its natural habitats, ecology and biodiversity. It is indeed the largest lagoon in Asia and chronicled as one of the preeminent biodiversity hotspots. India stood second in the world in its fish production contributing about 5.6% of the global production-extending livelihood to approximately 14 million people. Whereas the fish landing in most of the Lakes had decreases considerably. It was observed that the fish and fishery products of the Lake Chilika had marginally improved as well as the socioeconomic condition of local community. The biotourism had got wings and grown to several thousands of foreign exchange with infrastructural development in and around the Lake. Nevertheless, the natural and usual ecology of the Lake had lost its glory due to unnecessary anthropogenic interference resulting into loss of natural habitats, biodiversity and ecosystem as a whole. Present study is a retrospective of several other researchers carried on Lake Chilika along with research conducted by group of students between November 2009 to March, 2012. The statistical data collected was based on the secondary data available in several international and national journals, FAO database, Government gazettes, annual reports and information gathered from authorities in and around the Lake. However, the scientific data and erstwhile information was based on personal questionnaires, laboratory analysis and local literature related to ecology and species diversity.
