Developing countries such as Zambia are considered highly vulnerable to the adverse effects of climate change, since a large part of their economy is dependent on climate sensitive sectors (namely those dependent on natural resources) and their adaptive capacity is often limited by weak human and financial resources and by low institutional and technological capability. As part of the pilot phase of its Climate Change and Development Project, IUCN has been undertaking a climate change vulnerability assessment in three rural areas of Zambia, as well as similar activities in Tanzania and Mozambique.
