Climate change is a global phenomenon that became one of the most predominant environmental challenges facing our world today. Natural events and anthropogenic activities are responsible for increasing the negative impacts and risks associated with climate change. Developing countries in Asia and Africa are bearing much of the climate change burden due to rapid population growth, crop failures, and lack of required technological and financial resources to mitigate the risks. Afghanistan, like other developing countries, is highly vulnerable to the severe impacts of climate change. In Afghanistan, climate change is related to various adverse effects on water resources, agriculture, forests, biodiversity, increasing temperature, and changing the environmental landscape. This paper analyses the impact of climate change on environmental sustainability in Afghanistan. © The Authors, published by EDP Sciences, 2020.
