There are different possibilities to finance climate change activities. Some are market based, others are not. Within this last category, there is a possibility to launch Payment of Environmental Services PES1. Whatever activities are launched to cope with climate change issues should bring finance, ecosystems protection as well as poverty reduction in developing countries. However it is a complex and difficult path accessing climate change funds, which is also not really tailored for developing countries. Investment agriculture programmes are recognized to be a possible solution to climate change. Appraising their carbon balance is a way to highlight their capacity to cope with climate change issues. Climate change issues should not be seen as a new trend that will imply new conditions for developing countries. It is worth seeing the opportunities that could be brought by integrating climate change policies in the objectives of development.
