The United Nations Framework Convention on Climate Change (UNFCCC) defines climate change as &quot;climate change attributed directly or indirectly to human activity, which alters the composition of the global atmosphere and which is added to the natural variability of the climate observed over comparable time periods&quot;. Although developing countries are the ones that contribute the least with GHG emissions, forecasts on climate change generate great concern among them, since it is presumed that they will be the most affected by the related impacts. To reduce global GHG emissions and implement measures to adapt to climate changes, countries can carry out two types of actions: mitigation and adaptation. Mitigation aims both to reduce the net GHG emissions of the countries -for example by reducing the use of fossil fuels or emissions from different land uses-, as well as to increase the capture (or absorption and storage ) of carbon by ecosystems -as could be via conservation or reforestation- (IPCC, 2002). For its part, adaptation refers to the necessary adjustments in human (social and economic) or natural (ecosystem) systems to respond to expected or actual climatic stimuli, or to the effects of those climatic stimuli, in a way that moderates the damage or exploits its opportunities (IPCC, 2001).
