Threats to and management of Natura 2000 protected areas relative to agricultural practices
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

, 2013 本发明提供一种铜硫尾矿中金属铷资源回收的分选富集处理工艺，属于矿山固体废物资源化领域。其特征在于首先使用硫化浮选法回收尾矿中的硫化矿，使浮选尾矿中有效硫含量低于2％。然后以硫酸调节硫化浮选的尾矿矿浆pH至4，并以复配阳离子捕收剂浮选回收长石云母类矿物。铜硫尾矿经浮选后铷的回收率达到80％，铷含量富集3倍左右。本发明通过两步浮选法富集铜硫尾矿中的含铷矿物，有效降低了铷进一步回收的处理成本，且铜尾矿中的硫、锌、铜等资源富集到分选得到的硫化矿中，达到一定的品位可用于进一步的回收利用 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The similar physicochemical properties of alkali metal elements make the co‐enrichment and precise separation of Cs+ and Rb+ in complex brine systems highly challenging. Here, an all‐inorganic strategy is proposed, which achieves efficient enrichment and precise separation of Cs+ and Rb+ in high‐salt systems by constructing Sr2+/Ba2+‐based ...

Achieving Transboundary Water Security Through Water Innovations: A Framework and Cases
World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Alternative sources of freshwater, provided by various innovations, have long been available to countries facing acute water stress. We hypothesize that avoiding and/or resolving conflict with neighbors—caused by the uncertainty of continued access to shared surface water and groundwater sources—is another driver of innovation adoption ...

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...
