Cases abound where there has been win-win or win-lose or even lose-lose outcomes for conservation interventions meant to improve socio- and/or economic conditions. Sadly, even win-win cases tend to reverse over time (e.g. when donor funding disappears). Does anyone know of a case where an intervention has brought about 'net positive' outcomes for social, economic, and environmental health, and which have persisted long-term (>5-10 years)?
