Biting the bullet: how to secure access to drylands resources for multiple users por Mwangi, Esther, Dohrn, Stephan

“…Any attempt to secure access for multiple users in variable drylands environments should identify frameworks for conflict resolution, in a negotiated manner, crafting rules from the ground upwards, in addition to a more generalized or generic identification of rights.

Developing aerobic rice cultivars for water-short irrigated and drought-prone rainfed areas in the tropics por Zhao, D.L., Atlin, G.N., Amante, M., Cruz, Ma Teresa Sta, Kumar, A.

“…There was a low genetic correlation for yield across the two stress levels, and indirect selection under one stress level was not predicted to be effective in improving grain yield under the other, suggesting that screening genotypes under both nonstress and stress conditions for yield is needed to develop aerobic‐adapted varieties combining high yield potential with drought tolerance. The elite germplasm identified in this study is likely to be useful to farmers in water‐short irrigated and rainfed areas in the tropics.…”
