Destruction of rainforests and arablelands of Indonesia and Laos has led to catastrophic effects on their ecosystems. This chapter analyzes the current situation of the changing climate in these two countries. It discusses the issue that the burning of rainforests is largely causing climate change through carbon emissions, which are the major source of greenhouse gases and is leading to deforestation. Based on the figures of increasing palm oil production, increasing deforestation and high impact of climate change has been analyzed through regression analysis. Institutional investors as well as individuals play a key role in financing the expansion of the palm oil industry and can minimize the destruction caused by deforestation. As encouraging as it may sound, adaptation to climate change with the purpose of managing sustainable development, requires more than training and knowledge transfer. Lao PDR needs investment in technology, communications, infrastructure, and training and outreach programs to better prepare for natural disasters.
