Restoration Ecology, EarlyView.Abstract Introduction The fragmentation of the Atlantic Forest has caused severe biodiversity loss. In Paraná State, more than 96% of the original vegetation, predominantly semideciduous seasonal forest, has been degraded. Ecological restoration is a key strategy to reverse this scenario, aiming to recover environmental conditions equivalent to the ...

World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

Advanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the

Characterisation of Drought and Wet Events in the Paraíba do Sul River Basin—Brazil
International Journal of Climatology, Volume 46, Issue 9, July 2026.Trend analysis identified statistically significant reductions in precipitation (at the 5% significance level) at specific pluviometric stations in São Paulo and Rio de Janeiro, while other areas, mainly in Minas Gerais, experienced significant increases in annual and seasonal rainfall, particularly during summer and spring. These significant trends at
