LA REFORESTATION A GRANDE ECHELLE EST "DANS LES TETES"

53 MILLIARDS DE DOLLARS PAR AN POUR REHABILITER 150 MILLIONS D'HECTARES DE FORÊT DANS LE MONDE D'ICI 2020

Un peu moins de 3 fois la France. Il est reconnu que les espaces que l'on peut restaurer équivalent à la superficie de ce qui fut l'URSS, soit plus de 13 fois ce qui est proposé ici.

Restoration could be worth £53 billion to global economy

September 2011: A core commitment to restore 150 million hectares of lost forests and degraded lands worldwide by 2020 has been launched at a ministerial conference in Bonn. New analysis by IUCN estimates that restoring 150 million hectares would be worth £53billion per year to national and global economies.

At the Bonn Challenge Ministeral Roundtable, a select group of ministers and chief executives of international and non-governmental organisations and companies discussed how to benefit biodiversity and the fight against climate change through concrete restoration activities.

Ecosystems will become healthy and resilient
‘The restoration of lost forests will increase carbon stocks and result in healthy and resilient ecosystems, which will provide the multiple goods and services people need, and lead to an increase in biodiversity,' says Ashok Khoshla, President of IUCN, which acts as coordinator of the Global Partnership on Forest & Landscape Restoration (GPFLR).

The landmark commitment in Bonn comes as new analysis shows that more than two billion hectares of the world's deforested and degraded landscapes - equivalent to half the size of Asia - offer opportunities for restoration. This new global estimate is almost double the area previously considered restorable, thanks to improvements in the precision of mapping zones where climate and soils allow forests to grow.

This core committment is a realistic response
‘Recognising that national circumstances vary enormously, this core commitment to restore 150 million hectares is a robust and realistic response to the global assessment,' says Stewart Maginnis, IUCN's Global Director of Environment and Development. ‘What is needed urgently is a country-by-country assessment of how this commitment could be achieved in line with national economic development and conservation priorities, something we have already started doing in Ghana and Mexico.'

The 150 million hectare restoration target directly relates to existing international commitments on climate change and biodiversity. It will contribute to the biodiversity convention target calling for restoration of 15 per cent of degraded ecosystems by 2020, and the climate change convention goal on REDD-Plus, which calls for countries to slow, halt and reverse the loss and degradation of forests.

Cost-effective way to combat climate change
With preliminary analysis showing the value of restoring 150 million hectares to be £53 billion per year, forest landscape restoration can be seen as offering the world a highly cost effective way to combat climate change, create new jobs and contribute to rural development and livelihoods.

Earlier this year, IUCN expressed its support of Rwanda's historic announcement to restore the country's degraded landscapes border-to-border, predicting that it could be the beginning of the biggest restoration initiative the world has ever seen. With similar bold commitments expected to be announced at the Bonn event, co-chaired by IUCN and the German government, an unprecedented global initiative is clearly gathering momentum.
