Wildlife brings significant ecological,cultural, and economic benefits to countries andregionsaround the world. In many developing countries, it isan engine for tourism, job creation,and sustainabledevelopment. Populations of some of the most iconic wildlifespecies areunder threat due to the illegal wildlife trade(IWT) and other pressures. There is growing momentumin theinternational donor community to combat IWT and ensure thesurvival of these species and therealization of benefits tolocal communities that live with them.The goal of thisportfolio review is to assess the current state ofinternational donor funding to combat illegal wildlife tradeand to identify trends in investment in this sector inAfrica and Asia since 2010. Information on investments tocombat IWT is not readily available—donor procedures,processes, and systems to collect and report on funding dataare often complex and time-consuming. This portfolio reviewaddresses these challenges by collecting and analyzing IWTfunding information across international donors and fillsthe knowledge gap of international donor IWT funding trends.It collects data on the significant international donorfunding committed between January 2010 and June 2016 tocombat IWT in Africa and Asia, which totals over USD 1.3billion and is equivalent to approximately USD 190 millionper year. This analysis provides a baseline to track futuredonor funding commitments and can be used to supportadditional donor coordination efforts. The data collected,database created, online repository, and points of contactestablished with donors can be used to further understandfunding processes, effectiveness, and impacts and to informdonor strategic planning efforts. This analysis can be builtupon in consultation with recipient countries to establish avision of how best to optimize IWT financing in terms ofpriority geographic and thematic areas. Finally, a globalunderstanding of existing contributions, trends, and targetinvestment areas can facilitate collaboration and thesharing of lessons learned.
