Reconciliation of biodiversity conservation, food security and economic development in the tropics

(i) Development of policy strategies to correct market failures derived from the no recognition of ecosystem services value; (ii) evaluation of trade-offs between agricultural production and ecosystem services provision; and (iii) incorporation of ecosystem services lost through agricultural land conversion in national accounts. NUS project. PI.
