A conceptual framework for the assessment of tropical secondary forest dynamics and sustainable development potential in Asia por Chokkalingam, U., Smith, J., Jong, W. de, Sabogal, C.

“…In this paper, we present an intensification model based on the intensity of exploitation and use of forests and forest lands as a relevant framework for analysing the appearance, dynamics, and evolution of different types of secondary forests. The systematic driving forces responsible for the disturbances and subsequent secondary forest re growth tend to change and evolve along this continuum. …”

Silvicultura en la Amazonia Peruana: diagnostico de experiencias en la region ucanyali y la provincia de Puerto Inca por Nalvarte, W., Sabogal, C., Galvan, O., Marmillod, D., Angulo, W., Córdova, N., Colan, V.

“…However, much of the known experiences are barely documented and there is almost no systematization and analysis. This document describes the methodology, results and main conclusions and recommendations of a diagnostic study geared to improve the utilization of the wide silvicultural experience in the Peruvian Amazon with native species and to offer technical recommendations to improve the competitivity of silvicultural practices for the regeneration of residual, degraded and secondary forests. …”

The relative importance of rainfall, temperature and yield data for a regional scale crop model por Watson, J., Challinor, Andrew J.

“…However, the impact of input data errors on the skill of regional scale crop models has not been systematically quantified. We evaluate the impact of specific data error scenarios on the skill of regional scale hindcasts of groundnut yield in the Gujarat region of India, using observed input data with the GLAM crop model. …”

Operationalizing inclusive innovation: Lessons from innovation platforms in livestock value chains in India and Mozambique por Swaans, Cornelis P.M., Boogaard, Birgit K., Bendapudi, R., Taye, H., Hendrickx, Saskia C.J., Klerkx, Laurens

“…In addition to various structure and process components of inclusive innovation known from the literature, the study shows the importance of social organization, representation, and incentives to ensure a ‘true’ participatory innovation process, which is based on demand and embedded in the context; incremental change through so-called innovation bundles (i.e. combination of technical, organizational and institutional innovations) and reflexive learning (systematically challenging constraining factors) are critical to this. …”

Cowpea in evolving livestock systems por Grings, Elaine E., Tarawali, Shirley A., Blümmel, Michael, Musa, A., Fatokun, C.A., Hearne, S., Boukar, O.

“…Cowpea breeding programs have worked toward producing dual-purpose varieties that emphasize the production of grain and fodder since the late 1980s and have produced several that have become well accepted when tested on-farm. Systematic screening of cowpea genetic resources is important for advancing development of dual-purpose varieties. …”

Sustainable intensification?: Implications for the emergence of diseases por Grace, Delia, Bett, Bernard K., Unger, Fred, Hung Nguyen-Viet

“…Diseases are also emerging in livestock, companion animals, wildlife and plants. A systematic literature review was conducted to synthesize best available scientific knowledge about zoonotic disease transmission through direct or indirect domestic livestock-wildlife interaction, with emphasis on risk factors, drivers and trajectories of transmission, and promising interventions for controlling important zoonoses based on managing livestock-wildlife interaction.The study found complex associations with agricultural intensification and disease emergence: • Biodiversity, bush meat consumption, expanding ecotones, increases in synanthropoic species, land use change and livestock intensification are commonly cited and inter-related causes of emerging infectious diseases…”

“…Recent methodological improvements have significantly enhanced these distributions: more up-to date and detailed sub-national livestock statistics have been collected; a new, higher resolution set of predictor variables is used; and the analytical procedure has been revised and extended to include a more systematic assessment of model accuracy and the representation of uncertainties associated with the predictions. …”
