Abstract Central Asia (CA) is a critical agricultural region, contributing significantly to global food and cotton production, yet it faces increasing threats from extreme heatwaves (HWs) due warming. Despite this, the specific impacts of historical future HWs on CA's cropland remain underexplored. Here, using five bias‐corrected circulation models Inter‐Sectoral Impact Model Intercomparison Project Phase 3b (ISIMIP3b), we present detailed analysis exposure periods (1995–2014) under three Shared Socioeconomic Pathways (SSP126, SSP370, SSP585) for 2021–2100. Compared levels, find that heatwave frequency could increase by 199% 2081–2100 SSP126, while duration rise as much 852% 1143% SSP370 SSP585, respectively. Northern Kazakhstan emerges particularly vulnerable, with highest levels across scenarios. Interactive effects between climate shifts land‐use changes are dominant contributors, accounting over 50% total in each scenario. These findings highlight vulnerability various pathways, emphasizing urgency targeted adaptation strategies protect regional resilience and, extension, security.

Air temperature and relative humidity can be considered as two essential meteorological parameters in the determination of heat stress. The index (HI) includes both them it is appropriate for determining thermal conditions different climates. We investigated potential changes HI Mediterranean basin using simulations from Coupled Model Intercomparison Project Phase 6 (CMIP6) climate models under future scenarios (Shared Socio-economic Pathways: SSP2-4.5 SSP5-8.5) over period 2020–2099. Results reveal an important increase at end 21st century scenarios, with greater SSP5-8.5 scenario all basin.

Leaf anatomical traits are influenced by environmental and genetic factors; however, studies that investigate the genotype × environment interaction on these scarce. This study hypothesized (1) leaf anatomy of Coffea spp. genotypes is varied, (2) interactions between managements seasons significantly influence traits, inducing a clear adaptation to specific environments. Possible modifications in were investigated under different managements: full-sun monoculture at low-altitude (MLA), high altitude (MHA), agroforestry (AFS), winter summer. The all investigated, contributing 2.3-20.6% variance. Genotype contributed 2.3-95.8% variance key traits. effects management more intense than those season such as thickness, palisade parenchyma abaxial epidermis, polar equatorial diameter stomata.

Global warming has led to a notable increase in heatwaves globally and regionally. In spring 2022, South Asia witnessed an unprecedented heatwave with temperatures breaking historical records exceeding 5° C from climatological mean at several locations the northern Indian subcontinent. Here, using 3D tracking, this ranked most severe past 64 years, characterized by its protracted duration wide spatial extent. The excess atmospheric heat, represented temperature anomalies, during mega-heatwave triggered rapid snowmelt across snow-covered areas region, leading average loss of 42% snow cover 57% depth regional snowpack.

Abstract Growing season heatwaves that occur simultaneously over global croplands can negatively impact food baskets. The long-term changes of growing heatwaves, as well their impacts on productivity, are crucial to security, but remain unclear. Here, we investigated in the frequency, intensity and magnitude from past future croplands, based observations Coupled Model Intercomparison Project Phase 6 models. We introduced an index, gross primary productivity (GPP) exposure, a proxy overall cropland productivity. results show frequency have increased since 1950 will continue throughout 21st century. increase annual accumulated is mainly contributed by heatwave frequency. This leads global-scale GPP exposure with Asia, North America, Europe being most affected. continued dominated increases rather than itself. Under lower emission scenario SSP1-2.6, reduce 86.11% 330.47% relative under SSP2-4.5 SSP5-8.5 scenarios, respectively, end Our provide insights into potential hence security.
