Water-saving irrigated area expansion hardly enhances crop yield while saving water under climate scenarios in China

Communications Earth & Environment
Facing climate change risks of water shortages and crop yield losses, it is unclear in China that whether and how irrigated area expansion and technological yield improvement can increase production with less water. Here we used 2000–2018 as the baseline

Water Use [PDF]

Annual Review of Environment and Resources, 2003
Water managers and planners are slowly beginning to change their perspective and perceptions about how best to meet human needs for water; they are shifting from a focus on building supply infrastructure to improving their understanding of how water is used and how those uses can best be met.

Influence of acidified-biochar on phosphorus and potassium availability in alkaline sandy soil

Scientific Reports
Biochar application is recommended to enhance soil fertility, particularly in arid and semi-arid regions. In alkaline soils, acidifying biochar can help overcome high pH constraints and improve phosphorus (P) and potassium (K) availability.
