Location of Sri Lanka. Environmental issues in Sri Lanka include large-scale logging of forests and degradation of mangroves, coral reefs and soil. Air pollution and water pollution are challenges for Sri Lanka since both cause negative health impacts. Overfishing and insufficient waste management, especially in rural areas, leads to ...
The tank cascade system (Sinhala: එල්ලංගාව, romanized: ellaṅgāva) is an ancient irrigation system spanning the island of Sri Lanka. It is a network of thousands of small irrigation tanks ( Sinhala : වැව , romanized: wewa ) draining to large reservoirs that store rainwater and surface runoff for later use.
Sri Lanka's forests contain 61 million metric tons of carbon in living forest biomass (in 2010 [14]). The southwest portion of the island, where the influence of the moisture-bearing southwest monsoon is strongest, is home to the Sri Lanka lowland rain forests. At higher elevations they make the transition to the Sri Lanka montane rain forests.
Chena is the oldest cultivation method in Sri Lanka, it goes far back as more than 5,000 years.(Before the Anuradhapura Kingdom) [1] [2] it the dry zone, the recovery of a chena plot proceeds through various stages of succession, (active chena, abandoned chena, chena re-growth, scrub with pioneer three species, scrub with secondary tree species, secondary forest, secondary forest with primary ...
The park's elevation range from 20–60 metres (66–197 ft) with sparse rock outcrop. [3] The Mahaweli River flows from south to north through the centre of the park. The rich alluvial soil flood plains situated beside the river are featured by a number of shallow swampy depressions called "villus".
The Mahaweli Development program (Sinhala: මහවැලි සංවර්ධන වැඩසටහන) is known as the largest multipurpose national development program in the history of Sri Lanka and is also considered the keystone of the government's development program that was initiated in 1961.
It is also the primary threat to the survival of Sri Lanka's biodiversity. [2] Sri Lanka has 751 known species of amphibians, birds, mammals and reptiles of which 21.7% are endemic, and over 3314 species of vascular plants, of which 26.9% are endemic. [4]
Petroleum extraction disrupts the equilibrium of earth's carbon cycle by transporting sequestered geologic carbon into the biosphere. The carbon is used by consumers in various forms and a large fraction is combusted into the atmosphere; thus creating massive amounts of the greenhouse gas, carbon dioxide, as a waste product.
