TL;DR: In this paper, the authors present selected case studies that highlight the potential for economic and environmental benefits of taking action to remediate salt-affected lands and indicate that it can be cost-effective to invest in sustainable land management in countries confronting salt-induced land degradation.

TL;DR: The extent to which 286 recent interventions in 57 poor countries covering 37 M ha have increased productivity on 12.6 M farms while improving the supply of critical environmental services is shown.

TL;DR: The UK Government's Foresight Global Food and Farming Futures project as mentioned in this paper aims to improve dialogue and understanding between agricultural research and policy by identifying the 100 most important questions for global agriculture.

TL;DR: Sodic and saline-sodic soils occur within the boundaries of at least 75 countries, and their extent has increased steadily in several major irrigation schemes throughout the world as mentioned in this paper. But the use of these soils for crop production is on the increase as they are a valuable resource that cannot be neglected, especially in areas where significant investments have already been made in irrigation infrastructure.

TL;DR: The economic, social, and environmental impacts of different soil-amelioration options must also be considered as discussed by the authors, and a holistic approach is therefore needed to consider the cost and availability of the inputs needed for amelioration, the soil depth, the level to which sodicity needs to be reduced to allow cropping, the volume and quality of drainage water generated during ameling, and the options available for drainage-water disposal or reuse.
