South Asia is projected as one of the highly affected region due to geophysical conditions and socio-economic-demographic backwardness. It is cleared from the research reviewed that all most all the South Asian countries are more vulnerable to climate change than other regions since the majority of the population is hugely dependent on agriculture, fisheries, forestry and natural resources for their livelihood and it will increase the effect of climate change and global warming in South Asian countries. From 2000 to 2015 trend of material footprint and per capita domestic material consumption of all south Asian countries have been increased rapidly. The trend of biodiversity loss has shown that due to rapid palm oil extraction, timber extraction and large scale biofuel plantations within the south Asian region heavy ecosystem and biodiversity loss has occurred.
And also when comparing South Asian countries Sri Lanka is the country which generates highest per capita municipal waste and due to the rapid economic growth in India, the volume of waste is keep rising due to the migration of more people from the rural to the urban areas and spawning newer consumption patterns and social linkages. However, most of the countries are now initiated new waste disposal mechanisms and waste-management legislations are also being established and strengthened. Lack of resources, limited public awareness, absence of public trust of government agencies and inadequate institutional facilities are proving to be major barrios within the region.
Even though South Asian countries have historically low greenhouse gas emissions, due to rapid urbanization and industrialization South Asian countries going towards the carbon-intensive development path. These countries should concern pursue green growth strategies by finding new resources and energy options and to adopt a low carbon pathway.
