Rapid growth of the global economy has accelerated the degradation of the Earth's most important asset: the environment. Increasing poverty and challenges arising from climate change further threaten the planet's natural systems. With a rising global population, the demand on natural resources to cover even basic human needs is intensifying - supporting businesses that promote the sustainable use of natural resources and help ensure their long-term viability is imperative. As part of a pioneering movement to harness business towards effecting environmental change, The Nature Conservancy launched EcoEnterprises Fund in 2000 to provide investment capital to grow small eco -businesses in Latin America. There is a compelling need for financing this niche. Companies of this size truly drive change - creating the engine for economic activity and generating livelihoods for bottom of the pyramid rural peoples which brings about positive social and conservation impacts. EcoEnterprises Fund's portfolio highlights twenty-three cutting-edge companies, in expanding sectors such as organic agriculture, ecotourism, sustainable forestry, and non-timber forest products which include innovative industry first-movers-from organic shrimp to biodynamic flowers, and ready-to-drink smoothies made from the latest Amazonian berry. With a successful ten-year track record, EcoEnterprises Fund has valuable learning to share - from what pitfalls to avoid when structuring investments to what types of assistance entrepreneurs in these emerging environmental sectors need most. Portfolio for the Planet translates a decade of experience into accessible lessons for both veterans and newcomers in the field: for those interested in investing in sustainable businesses, discovering novel approaches to environmental conservation, or seeing entrepreneurs pursue their dreams.
