Simulating rangeland ecosystems with G-range: Model description and evaluation at global and site scales por Sircely, Jason A., Conant, Richard T., Boone, Randall B.

“…These drivers forcing widespread changes in rangeland ecosystem processes and vegetation dynamics create two-way interactions and feedback loops between biogeochemistry and vegetation composition. To support spatial simulation and forecasting in the global rangelands, the G-Range global rangelands model couples biogeochemical submodels from the CENTURY soil organic matter model with dynamic populations’ submodels for herbs, shrubs, and trees. …”

Opportunities for increasing livestock water productivity in the Nile River Basin por Peden, Donald G., Faki, H., Alemayehu, M., Mpairwe, D.R., Herrero, Mario, Breugel, P. van, Haileslassie, Amare, Taddesse, G., Awulachew, Seleshi Bekele

“…Four strategies to increase LWP are selection of animal feeds derived from plant materials with high crop water productivity, improved water conservation through better management of watering sites, vegetation and soil on grazing, crop and riparian lands, adoption of technologies to improve animal health, genetics, nutrition and husbandry, and strategic allocation of watering sites to adjust grazing pressure to sustainably match the spatial distributions of pasture and drinking water availability. …”

Bridging the gap: Integrating crop pests and pathogens into agricultural foresight models for food security assessments por Petsakos, Athanasios, Montes, Carlo, Falck-Zepeda, José B., Pequeno, Diego Noleto Luz, Schiek, Benjamin, Gotor, Elisabetta

“…Regional and global economic models, combined with spatially distributed crop growth simulation models and hydrology models that simulate water supply and demand across sectors (among others), represent the most widely used quantitative approach for addressing questions related to food security under alternative future scenarios (e.g., for a recent reference, van Dijk et al., 2021). …”

Open property and complex mosaics: Variants in tenure regimes across pastoralist social-ecological systems por Robinson, Lance W.

“…This view holds that the quintessential features of dryland pastoralist systems—limited and highly variable rainfall, low resource density, mobility, and institutions and norms that emphasize flexibility and access—can result in pastoralist herders dynamically distributing and redistributing themselves across a territory without the assumed benefit of clear boundaries or of collective decision-making and rules. …”
