The article reviews some of the critical issues for including Reduced Emissions from Deforestation and forest Degradation (REDD) into a new global climate agreement. Four different REDD models (regimes) are discussed based on two dimensions: scale (national vs. project) and funding (market vs. fu...
Complex ecological and social processes in tropical forests imply that observations on any single element of the system do not provide an adequate basis for sound forest management. A collaborative modelling process engaging all relevant stakeholders led to a shared understanding of how to manage...

Participatory modelling can be a useful process to encourage critical examination of livelihood options and foster sustainable natural resource use through enhanced social learning, collective action and mobilization. The broom-grass group in the Mafungautsi forest reserve serves as a case study ...

Hydrological models bring clarity and consensus to challenging policy issues.
Adoption of animal traction in sub-Saharan Africa has historically been slow and stagnant. This is despite considerable efforts by researchers and development planners to introduce the technique among smallholder semi-subsistence farmers in a large number of countries. Based on a simulation model...

OASIS, an irrigation diagnosis model, is applied to the Zhanghe Irrigation System in central China to investigate the contribution of smaller local storages (in �melons on the vine� configuration) as compared with the main reservoir. Results show that local storages are more important in normal-t...

A mixed model simultaneous procedure is described to estimate location parameters for the right-censored and uncensored traits in the practical animal breeding data set for herd-life and milk production. Location parameters of fixed effects represented by herd -year effects and random effects rep...

Past attempts to alleviate the problems of poor farmers engaged in mixed-crop-livestock production have generally focussed on the design and diffusion of new technologies targeted on specific components of the agroecosystem. Unfortunately, such piece-meal efforts have had little impact in the dev...

A software package to generate daily weather data for Latin America and Africa is described. The program is based on a stochastic weather generator that uses a third-order Markov process to model daily weather data. The model has been fitted to data from more than 9200 stations with long runs of ...
