Grain legumes increase yield stability in maize based cropping systems por Chimonyo, Vimbayi Grace Petrova, Snapp, Sieglinde S., Chikowo, Regis

“…Functional crop diversity enhances crop productivity, stability, and food security through efficient nutrient cycling and water utilization; however, performance is variable under marginal environments. We applied stability analysis to assess impacts of grain legume integration on maize (Zea mays L.) grain yield, yield stability, N use efficiency (NUE), and ability to meet household protein requirements. …”

Untangling outcomes of de jure and de facto community-based management of natural resources por Agarwala, M., Ginsberg, J.R.

“…This underscores that although the global movement to formalize community‐management regimes may address some forms of inequity and may produce better outcomes, it does not ensure resource sustainability and may lead to greater marginalization of users. Comparison of governance systems that differentiate between initiatives that legitimize existing de facto regimes and systems that create new de facto regimes, investigations of new top‐down de jure regimes, and studies that further examine different approaches to changing de jure regimes to de facto regimes are avenues for further inquiry.…”
