Population, Health, and Environment(PHE) integrated projects are a part of this new generation. These projects not only aim to achieve goals in these fields, but to better understand the effects of these integrated approaches. Conservation International (CI) combined their extensive experience designing and implementing conservation projects, with the new understanding of the effects of integrated projects to create more valuable PHE projects. The idea in these projects was to reduce population pressures on biodiversity hotspots. CI began the Healthy Families, Healthy Forests project in 2002 for hotspots in Cambodia, Madagascar, and the Philippines. With the help of other health and conservation organizations, CI’s PHE projects achieved many goals in all the project sites. Poor and rural populations were supplied with medical services such as vaccinations, family planning, and reproductive health(FP/RH), as local health care providers were trained. Education had lead to alternative livelihoods and behavior changes fostering biodiversity conservation and forest management. CI's success is in applying a PHE project that bridges the gap between population, health, and environment and promotes human and environmental health.
