Overstocking the range: A critical analysis of the environmental science of Sahelian pastoralism por Turner, M.

“…I argue that the persistent reliance by environmental analysts on carrying-capacity models oversimplifies range ecology and excludes social processes from causal analyses. Both regional stocking rates and the seasonality of livestock distributions should be treated as proximate factors, each affected by biophysical and socioeconomic conditions. …”

Sources of resistance in species of Brachiaria to foliar blight disease caused by Rhizoctonia solani por Kelemu, Segenet, Miles, John W., Bonilla, Ximena P., Badel, JL

“…This study developed a fast and reliable method of inoculating Brachiaria, a genus of tropical forage grasses, with Rhizoctonia solani, the causal agent of foliar blight disease. Using this method, 42 Brachiaria accessions were inoculated in both field and glasshouse, and their reactions to R. solani evaluated. …”

Sustainability and food and nutrition security. A vulnerability assessment framework for the Mediterranean Region por Prosperi, P., Allen, T., Padilla, M., Peri, I., Cogill, Bruce

“…Derived from natural disaster and sustainability sciences, a vulnerability approach, enhanced by inputs from the resilience literature, has been adapted to analyze the main issues related to food and nutrition security. Through causal factor analysis, the resulting conceptual framework improves the design of information systems or metrics assessing the interrelated environmental, economic, social, and health dynamics of food systems.…”

Modeling sustainable food systems por Allen, T., Prosperi, P.

“…By acknowledging the systemic nature of sustainability, this approach allows consideration of causal factor dynamics. In a stepwise approach, a logical application is schematized for three Mediterranean countries, namely Spain, France, and Italy.…”
