It is not likely that the 2010 drought in Thailand has been caused by deforestation as reported (Army says dry spell due to deforestation, Bangkok Post, June 30, 2010). Thailand has a long history of droughts that come in cycles normally synchronized with the El Nino phenomenon. It is part of a well established weather pattern in this part of the world. These droughts are caused by insufficient rainfall. It is not possible for deforestation to affect rainfall. It may be true that deforestation worsens the effects of droughts and floods but it does not cause droughts just as it does not cause floods.
