Integrating Research Results into Decision Making about Natural Resource Management at the Forestagriculture Interface: a Case Study in the Congo Basin por Ngobo, M., Weise, Stephan F., Peters, M.

“…So far, the Project main outputs include: baseline environmental, agronomic, economic, and social datasets compiled and assessed in 6 landscape mosaics of the Forest Margin Benchmark; different resource management options for increased productivity of annual crop-based systems, perennial crop-based systems, and community-managed natural resource systems tested with farmers in the benchmark area; integrative landscape-level models and participatory community action methodologies developed; local capacity built in the use and interpretation of the models and methodologies and their outputs/outcomes; and mechanisms for policy formulation and dialogue improved at the local, provincial and national levels, targeting landscape mosaic and natural resources management.From the ASB experience, it is concluded that there is no single ‘best bet' solution to rural poverty alleviation at the forest-agriculture interface of Congo basin region. …”

A Bayesian analysis of longitudinal farm surveys in Central Malawi reveals yield determinants and site-specific management strategies por Snapp, Sieglinde S., Han Wang, Fisher, M., Viens, F.

“…To improve plant nitrogen status, fertilizer was effective at higher productivity sites, whereas soil carbon and organic inputs were important at marginal sites.
