Earth-Eval is an online community of practice hosted by the Global Environment Facility Independent Evaluation Office (GEF IEO) in Washington, D.C. Its overarching goal is to establish standards and norms, support capacity development, and share good practices in evaluations. Our members are a global network of monitoring and evaluation practitioners in government and development cooperation agencies, civil society organizations, and academia. Earth-Eval (formely known as Climate-Eval) was formed after the 2008 International Conference on Evaluation of Climate Change and Development in Alexandria, Egypt.

EvalforEarth is a joint initiative of the evaluation offices of FAO, WFP, CGIAR, and The GEF.
