Contracting with private landholders for labor towards production of environmental services (payment for actions) or the environmental services themselves (payment for outcomes) is reliant on the environmental organization’s ability to monitor and assess the environmental outcomes provided....

This paper describes a complex, dynamic simulation model that has been developed for the analysis of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli) in rice farming systems in the Philippines. Users of the model may simulate any feasible...

Conservation and restoration of native vegetation is often a gradual process which may require many years to transform an ecosystem from one vegetative state to a target ecosystem. This process is stochastic, with some changes potentially irreversible. In contrast, contracts with landholders to...
