Answer:
Forests support countless and diverse species, provide essential ecosystem services, stabilise climate, regulate the water regime, besides providing a direct source of livelihood for more than one billion people worldwide.
Having a two-fold role in climate change, forests can cause up to half of the global greenhouse emission due to land use changes. At the same time, they are an excellent sink for carbon dioxide, the single biggest cause of global warming.
Having a huge potential to absorb about a sixth of global carbon emissions, forests across the globe provide one of the cheapest natural and low-tech ways to offset greenhouse gas emissions. When managed in a sustainable manner, reforestation and landscape restoration of forests help reducing vulnerability of both forest and forest-dependent communities to the consequences of climate change.
Since climate change is one of the major drivers of degradation of forests and disturbances to forest dependent communities, environmentalists and foresters are now supporting the strategy of assisted natural regeneration also as an alternative to tree planting, which is low-cost, easy to adopt and a high-impact intervention to restore and rejuvenate degraded forests and biodiversity, and sequester carbon as well.
Restoring 350 million hectares of degraded forests by 2030, which could sequester up to 1.7 gigatons of carbon dioxide equivalent annually, is main objective of the Bonn Challenge, a land restoration and tree plantation programme initiated by the UN Convention to Combat Desertification.
Considering the many roles and services of trees, there had been initiatives at the international, national and local levels by increasing the tree cover and protecting and developing existing forest wealth, which are being subjected to many challenges by human activities.
Notable among these initiatives are the Trillion Trees initiative of the United Nations Environment Programme and Food and Agriculture Organisation, Plant a Billion Trees by non-profit Nature Conservatory and Billion Trees Tsunami of Pakistan.
In India, the federal government launched the Green India Mission (GIM) in 2014 to increase forest cover by five million hectares and to improve the quality of forest cover on another five million hectares of forest and non-forest lands.
