Food security and agriculture in the Western Highlands of Guatemala por López Ridaura, Santiago, Barba-Escoto, Luis, Reyna, C., Hellin, Jonathan, Gerard, G., Wijk, Mark T. van

“…Food insecurity is concentrated in the Western Highlands of Guatemala (WHG) where indigenous communities have been the main victims of social, political and economic marginalization. In this study we characterize the diversity of farming households in the WHG, identify the main sources of food for different types of farm households and assess their food security status through a simple, yet robust, potential food availability indicator. …”

Electric pumps, groundwater, agriculture and water buyers: evidence from West Bengal por Buisson, Marie-Charlotte, Balasubramanya, Soumya, Stifel, D.

“…We find that electric-pump ownership increased agricultural outputs both at the extensive and intensive margins in both seasons. The number of clients served by electric-pump owners was greater than those served by diesel-pump owners, but there was only a small difference in total irrigated areas, suggesting that electric-pump owners sell water to farmers with smaller land holdings. …”

Three approaches to restoration and their implications for social inclusion por Sigman, Emily, Elias, Marlène

“…We argue that: (1) restoration aimed at bringing ecosystems back to a previous state, or “return” restoration, favors natural science at the landscape scale over social inclusion at the community scale; (2) restoration seeking to recreate functional ecosystems in locations away from where the degradation has occurred, or “reorganization” restoration, fails to adequately address historical inequities and perpetuates legacies of exploitation; and (3) “resilience” oriented restoration is promising but remains theoretical, and risks instrumentalizing marginalized communities and their lands as experimental sites for restoration. …”
