In 2006 Oak Foundation developed a ten-year strategic plan that guides its grant-making in Belize and the wider Mesoamerica region. The purpose of this report is to provide a detailed description of regional grantmaking in 2012 and inform on the progress of active grants from previous years.The report is divided into four sections: 1) Introduction, 2) Mesoamerican Reef Eco-region Programme grants 2012; 3) active grants from previous years; and 4) a glossary of abbreviations. The Oak Belize Foundation is a part of a wider group of charitable and philanthropic organisations established in various countries worldwide. The resources of Oak Foundation originated from an interest in the Duty Free Shoppers business that Alan Parker helped to build. Since its establishment over a decade ago the Foundation has made over 2,700 grants to not-for-profit organisations across the globe. The office in Belize is not a grant-making organisation. Its staff provide technical support and expert advice that informs the grant-making of Oak Foundation in the Mesoamerican Reef region. Other philanthropic organisations which partner with Oak Foundation administer the grants described in this report. Oak Foundation's Mesoamerican Reef Eco-region Programme Goal is to develop an ecologically representative network of marine reserves that maintain the health of the barrier reef ecosystem and its wildlife, and that support the food security and sustainable economic development of local coastal communities.
