Book excerpt: More than twenty years after the Earth Summit was held in Rio de Janeiro in 1992, both national and international actors in governmental and nongovernmental fields are still searching for insights into how sustainable development can be advanced and environmental concerns incorporated into the development agenda more effectively. Moreover, climate change has emerged as a preeminent challenge to both the environment and to development. Evaluating Environment in International Development provides international perspectives and in-depth knowledge of evaluating development and the environment and applies evaluation knowledge to climate change mitigation and adaptation. The book focuses on the approaches and experiences of leading international organizations, not-for-profits, and multilateral and bilateral aid agencies to illustrate how systematic evaluation is an essential tool for providing evidence for decision-makers. It provides novel and in-depth perspectives on evaluating environment and sustainability issues in developing countries. Moving beyond projects and programmes, it considers aspects such as evaluating normative work on the environment and evaluating environmental consequences of economic and social development efforts. This original collection should be of interest to scholars of environment studies, development studies, international relations, sustainable development and evaluation, as well as practitioners in international organizations and development and environmental NGOs.
