Air pollution has large impacts on the Hindu Kush Himalaya (HKH), affecting not just the health of people and ecosystems, but also climate, the cryosphere, monsoon patterns, water availability, agriculture, and incomes (established but incomplete). Although the available data are not comprehensive, they clearly show that the HKH receives significant amounts of air pollution from within and outside of the region, including the Indo-Gangetic Plain (IGP), a region where many rural areas are severely polluted. In addition, the HKH receives trans-boundary pollution from other parts of Asia.

The rapidly growing construction sector in India has a large resource foot print but can offer a vast potential to mitigate and adapt to climate change. Greening the building sector is feasible through various policy measures and incentives to deal with recycling and waste treatment, reduction in energy use, emissions and the use of other hazardous substances, which have several public and private benefits.

This paper uses 620 forest plot measurements taken from a nationally representative sample of 130 Nepal community forests combined with information on forest collective action to estimate the effects of collective action on carbon per hectare and three additional measures of forest quality. We use three measures of forest user group collective action, including membership in the Nepal Community Forestry Programme (CFP).

Although intentional use of fires to transform land has decreased globally (1, 2), particularly among highly capitalized countries through regulatory and market-orientedapproaches and moral suasion, regulatory strategies have been less effective in southern and eastern Asia (see table S21). Some densely populated agricultural regions in China and India buck the global trend, showing increases in agricultural fires (2).
