The UN has launched a tree plantation campaign in Pakistan's flood-hit areas and plans to plant 200,000 trees in 400 villages.

The campaign is part of an initiative by the UN Human Settlements Programme or the UN-Habitat. It is the UN's agency for human settlements aimed at promoting socially and environmentally sustainable towns with the goal of providing adequate shelter for all.

As many as 30,000 families across the country will take part in the 45-day plantation campaign, the Online news agency reported.

The agency said that as part of the reconstruction and rehabilitation process after the floods of 2010 and 2011, trees were being cut from forests and there were no plans of reforestation.

Families in the affected areas, besides using timber for shelter construction, use them as fodder for animals and the wood as fuel.

The agency is trying to mobilise the affected communities to plant trees at places such as the kitchen gardens, schools, mosques, or community land.
