The objective of this paper is to reviewexperience with completed country environmental analysis(CEAs) to improve the effectiveness of CEAs as a strategicanalytical tool. Through in-depth analysis of the process,methodologies, costs, and results of completed CEA pilots,the paper assesses how effective CEAs have been in informingand providing strategic guidance to the Bank and clientcountries on environment-development issues and the extentto which they have facilitated donor coordination. Theanalysis carried out in this paper also provides feedback onwhen to prepare a CEA, how to prepare and structure CEAs,and how to use specific methodologies and processes ininfluencing policy dialogue with partner countries. Thefindings are of potential interest to World Bank sectormanagers, country directors, CEA task teams, andenvironmental staff, but also to development partners whocarry out work similar to CEAs. The paper is based on a deskreview of completed CEAs and on interviews with taskmanagers and members of CEA teams. Several reports,including a fieldwork-based assessment of the Ghana, India,and Guatemala CEAs commissioned by the EnvironmentDepartment; a review on Tunisia by the Quality AssuranceGroup (QAG); and a report commissioned by the Latin Americaand Caribbean Region, based on in-country assessments ofcompleted CEAs, have also informed this study. A detailedcase study analysis of each completed CEA was prepared forthis exercise; it substantively informed the review and isavailable as a background paper. The original CEA conceptnote proposed that CEAs have three main building blocks: (a)establishment of environment-development priorities linkedwith growth and poverty reduction, (b) assessment of theenvironmental implications of sector policies, and (c)institutional analysis. Assessing CEAs against this buildingblock structure, the review highlights several findings.
