Because the UN's definition is unclear, "forests" under REDD may include monoculture tree plantations or even genetically engineered trees.
For example, it may be possible to make a reasonably accurate projection of deforestation emissions in a confined area for the purposes of a REDD trial, but it can be an entirely different exercise making the same projection for a whole country.
Conservation organizations, for example, have been most enthusiastic about the possibilities that REDD offers for forest preservation, even in a market-based offset form.
How do you ensure that REDD will not adversely impact the rights and livelihoods of the millions of people who live in or around forests, especially in poorly governed states?
The coalition made its public debut in December 2005 at the United Nations Climate Change Convention in Montreal, where Conrad offered a proposal for including REDD in the post-Kyoto climate treaty, partly as a means of encouraging poor countries to contribute to the global fight against climate change.
REDD currently serves sixty-four nations from Africa, Asia-Pacific, Latin America, and the Caribbean.
Redd previously served as senior marketing director of Halstead Property Development Marketing, where she worked on prestigious projects including 11 Central Park North, 88 Morningside, Northside Piers, 80 Metropolitan, Steel Street Lofts and over 70 more.
If REDD credits are approved in Paris, countries and companies could pay peasant farmers in Ecuador or elsewhere to protect trees that programmes like REDD+ claim they otherwise would have chopped down -- thereby avoiding the need to make difficult structural changes to cut emissions at home.
REDD (Reducing Emissions from Deforestation and Forest Degradation) is a global program promoted by the UN, industrialized nations, and international financial institutions like the World Bank.
When REDD was first proposed, many commentators argued this mechanism would not only mitigate climate change but also provide biodiversity and forests with the hard international law regime that had so far been missing.
In turn, in the face of a growing momentum towards implementation of emissions-reduction measures, this examination raises wider questions about effective indigenous and local community participation in REDD + schemes, as well as in the development of legal safeguards.
The REDD program, Reducing Emissions from Deforestation and Forest Degradation, was promoted by the United Nations to protect vulnerable forests and stem climate change.
