The yearly return of the falcons to Doyang is a story of community conservation, not of technology or of the birds settling in India.

In the restructured Act the plant schedule moved from the old Schedule VI to the new Schedule III, and it still protects a short list of species such as the blue vanda, the pitcher plant and other threatened orchids and cycads, whose uprooting and trade are controlled.

These protected areas lie at the southern tip of the Western Ghats, where the Agasthyamala Biosphere Reserve spreads across Kerala and Tamil Nadu.

The World Toilet Organization is a non-profit body, not a UN agency, and it works through advocacy and training rather than by giving grants to countries.

A membrane bioreactor treats sewage or industrial effluent by combining biological breakdown of waste with filtration through fine membranes. In a membrane bioreactor (MBR), microorganisms in an aerated tank digest the organic matter in wastewater, as in the conventional activated sludge process.

The Forest (Conservation) Act was passed in 1980 to stop the steady loss of forest land to mining, roads, dams and townships.
