The value of forests and tree-based ecosystems extends far beyond carbon sequestration, according to a new report, which suggests trees are in fact the foundation of sustainable societies.

Experts compiling a report for the UN have called on governments to take a more holistic view in policy making, including looking at the role of trees and forests in reducing pollution and providing benefits for people and the wider natural environment.

A report released at an event in Jakarta, Indonesia to mark the International Day of Forests on Friday (19 March) calls for efforts to reduce deforestation and the degradation of forests in line with the UN REDD initiative, part of the international organisation's programme for tackling anthropogenic climate change.

The report's authors want to see policies that support tree growth and sustainable forestry integrated more into areas traditionally seen as separate, interlinking sustainable initiatives to support forests with other key sectors of a modern country, such as agriculture, energy, water resources, finance, transport, industry, trade and cities.

The authors said more holistic, pro-forestry policies, tailored to support the most vulnerable in society, would benefit all nations. They added that the approach could increase the value and impact of other initiatives, such as agroforestry projects being implemented within these sectors in many countries, and form a critical element in a green economy.

They also said more and better forest management options could conserve biodiversity and ecosystem services whilst reducing emissions and making communities and agroecosystems around the world more resilient to the effects of climate change.

Each year, the International Day of Forests highlights the unique role of forests in the environment and in sustaining livelihoods. The theme this year is Celebrating Forests for Sustainable Development.

"It is important day to remind us to save our planet as it is the only one we know which has trees," said Tony Simons the Director General of the World Agroforestry Centre (ICRAF). "Trees are what made the Earth habitable for mammals, and destruction of forests will lead to the ultimate destruction of mammals – including humans. Trees are one of the few things which live longer than humans – a true intergenerational gift," he added.

The authors of the newly released report maintain that forests and trees are key to sustainable development. Not only do they store carbon, they support biodiversity, regulate water flows and, reduce soil erosion. Nearly 1.6 billion people worldwide depend on forests as a source of food, medicines, timber and fuel.
