Poverty &Public Policy, Volume 18, Issue 2, June 2026.ABSTRACT Cash transfers have become an increasingly important social protection tool in development and humanitarian contexts. In developing countries, cash transfers can be used to build economic resilience. This study examines the effects of unconditional cash transfers on asset accumulation among low‐income households in rural Northern Uganda. Using

Risk, Hazards &Crisis in Public Policy, Volume 17, Issue 2, June 2026.ABSTRACT The article examines how ‘soft’ information functions in rational organisations that emphasise hard information, and how this affects safety. Drawing on fieldwork in a high‐security prison, we analyse how frontline personnel interpret soft information about potential disturbances. We identify three coexisting institutional logics shaping these

Functional Ecology, Volume 40, Issue 6, Page 1921-1932, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Most terrestrial plant species form symbioses with arbuscular mycorrhizal fungi (AMF). However, the below‐ground carbon (C) allocation of plants and the nutritional and growth benefits provided by AMF within this symbiosis vary greatly across species and environments ...

Differences in characteristics between naturalized threatened plants and other threatened plants
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.

Policy, Waste, and Power: Textile Dumping in Chile's Atacama Desert
Latin American Policy, Volume 17, Issue 2, June 2026.ABSTRACT Globally, 87% of textile fibers end up incinerated or in landfills, with Chile bearing the brunt of this crisis. Every year, 39,000 tons of discarded clothing are illegally dumped in the Atacama Desert, turning it into a sacrifice zone for the Global North's waste economy.

Gongye shui chuli, 2019 河南某煤化工企业采用分质预处理和多种工艺组合方式深度处理煤化工废水，即采用水解酸化+UASB预处理乙二醇废水，两级破氰技术预处理煤气化废水，经预处理的废水与其他生产废水、生活污水混合后采用A/O生化处理；对生化出水、循环排污水和除盐排污水的混合水采用臭氧氧化+曝气生物滤池（BAF）组合工艺深度处理。结果表明，最终出水水质满足《污水综合排放标准》（GB 8978-1996）的一级标准和《城镇污水处理厂污染物排放标准》（GB 18918-2002）的一级A标准。

Spatially Downscaling of Future Food Demand for Policy Planning
World Food Policy, Volume 12, Issue 1, May 2026.ABSTRACT Understanding the subnational dynamics of food demand, while accounting for the evolution of the agrifood system at the global level, remains a challenge for designing food policy to ensure food security. To link global agrifood systems with subnational food policy planning, we downscale per capita food demand for 62 food commodities at the ...

Gongye shui chuli, 2017 采用O3-H2O2工艺取代Fe/C-H2O2工艺对某农药厂废水进行预处理，对比研究了2种工艺对废水COD的处理效果，以及对后续生化处理的影响。结果表明，相比于Fe/C-H2O2工艺，O3-H2O2预处理对废水COD具有更好的处理效果，经O3-H2O2 和Fe/C-H2O2 预处理后，废水B/C 分别为0.64 和0.48。污泥镜检结果表明，废水经O3-H2O2工艺处理后，后续生化处理好氧池丝状菌生长量降低，从而抑制了污泥膨胀的产生。
