Abstract Drylands, comprising semi‐arid, arid, and hyperarid regions, cover approximately 41% of the Earth's land surface have expanded considerably in recent decades. Even under more optimistic scenarios, such as limiting global temperature rise to 1.5°C by 2100, semi‐arid lands may increase up 38%. This study provides an overview state‐of‐the‐art regarding changing aridity arid with a specific focus on its effects accumulation availability carbon (C), nitrogen (N), phosphorus (P) plant–soil systems. Additionally, we summarized impacts rising biodiversity, service provisioning, feedback climate change across scales. The expansion ecosystems is linked decline C nutrient stocks, plant community biomass diversity, thereby diminishing capacity for recovery maintaining adequate water‐use efficiency plants microbes. Prolonged drought led −3.3% reduction soil organic (SOC) content (based 148 drought‐manipulation studies), −8.7% decrease litter input, −13.0% absolute decomposition, −5.7% decomposition rate. Moreover, substantial positive loop warming exists, primarily due increased albedo. loss critical ecosystem services, including food production water resources, poses severe challenge inhabitants these regions.

Reducing carbon emissions and increasing sinks have become the core issues of international community. Although coastal blue ecosystems (such as mangroves, seagrass beds, salt marshes large algae) account for less than 0.5% seafloor area, they contain more 50% marine reserves, occupying an important position in global cycle. However, with rapid development economy continuous expansion human activities, wetlands suffered serious damage, their sequestration capacity has been greatly limited. Ecological restoration emerged a key measure to reverse this trend. Through series measures, including restoring hydrological conditions damaged wetlands, cultivating suitable plant species, effectively managing invasive species rebuilding habitats, ecological is committed functions service value. Therefore, paper first reviews research status influencing factors wetland sinks, discusses objectives, types measures various projects, analyzes impact these projects on sink function, proposes suggestions incorporating enhancement into restoration.

Perennial trees are often stressed by drought more than once during their life cycle. Our study exposed three-month-old Alhagisparsifolia, with (drought-primed) or without (nonprimed) prior stress to subsequent for two months, aiming reveal whether pre-exposure could enhance seedling resistance and investigated possible underlying mechanisms. Root biomass, leaf relative water content, chlorophyll a, carotenoids were significantly higher in drought-primed nonprimed seedlings. They also had reduced concentrations of malondialdehyde, hydrogen peroxide (H2O2), superoxide anions (O2•−), indicating relief from oxidative stress. This was associated a coordinated upregulation enzymes scavenging O2•− H2O2, particularly dismutase (SOD) catalase (CAT), the maintenance ascorbate-glutathione (AsA-GSH) redox pool enzymatic activities (ascorbate peroxidase, mono- dehydroascorbate reductase, glutathione reductase), leading better regulation reactive oxygen species. The failure seedlings upregulate SOD, CAT, AsA-GSH cycles nevertheless made susceptible increased levels strigolactones, jasmonic acid, abscisic acid roles displayed gibberellic indole acetic acid. A principal component analysis showed that responded differently if they previously suffered drought, mainly due capacity pigment protection, scavenging, osmolytes, anti-stress hormones. provides insights into benefits memory induced early priming as strategy overcoming

As valuable sources of plant-based protein, leguminous vegetables (grain legumes) are essential for global food security and contribute to body growth development in humans as well animals. Climate change is a major challenge agriculture that creates problems the plants. However, legume productivity threatened by climate factors, including rising temperatures, shifting precipitation patterns, increased atmospheric carbon dioxide levels, intensified extreme events, altered pest/pathogen activity. This review synthesizes approximately 136 studies assess effects on crops. Under all emissions trajectories, mean temperatures projected rise beyond optimal growing thresholds 2050, carrying yield reductions between 10 49% beans, soybeans, cowpeas, lentils without adaptation measures. The elevated may transiently enhance yields up 18%, but benefits dramatically decline above 550 ppm cannot offset other impacts. Altered rainfall along with recurrent drought heat waves also expected decrease crop yields, seed quality, soil nitrogen levels worldwide. Furthermore, proliferation pests fungal diseases poses significant risks, amplified shifts 84% reviewed studies. These multifaceted impacts threaten gains sustainably meeting protein demand. Realizing resilience will require accelerated heat/drought-tolerant varieties, enhanced climate-informed agronomic practices, strong policy interventions, social safety nets explicitly supporting producers, addition policies/steps governments taking address challenges crisis. highlights adaptations mechanisms required crops thrive fulfill their roles nutrition.

Revitalizing oasis agriculture, an age-old human endeavor, has historically played a crucial role in sustaining biodiversity and ecosystems arid regions. Nevertheless, this enduring practice now faces contemporary challenges, including global warming, water scarcity, soil erosion, negative activities associated with urbanization. This comprehensive review delves into diverse literature across disciplines, covering topics such as conservation, restoration, agroforestry, Oasis Holistic Management, the aim of addressing these challenges. The analysis strongly advocates for urgent adoption sustainable practices, precision irrigation, polyculture, organic farming, community-based initiatives, to ensure survival agriculture foster long-term environmental social responsibility. study underscores imperative need development “comprehensive, flexible, forward-looking management strategies” guide revival farming. By consolidating information from various studies, it lays groundwork informed decision-making policy formulation. As part revitalizing agricultural ecosystem climate crisis, we propose noninvasive tool assessing carbon sequestration effectiveness based on tree specifications. Recognizing pivotal vegetation mitigating ecological impact facing crises, explored parameters influencing plant sequestration, biomass production, growth rate, longevity, root structure, leaf average temperature tolerance.

Thinning-a widely used forest management practice-can significantly influence soil nitrogen (N) cycling processes in subtropical forests. However, the effects of different thinning intensities on nitrification, denitrification, and their relationships with properties microbial communities remain poorly understood. Here, we conducted a study China applied three treatments, i.e., no (0 %), intermediate (10-15 heavy (20-25 investigated intensity potential nitrification rate (PNR), denitrification (PDR), communities. Moreover, explored among physicochemical properties, community structure, transformation rates under intensities. Our results showed that increased PNR by 87 % 61 decreased PDR 31 50 compared to control, respectively. Although bacterial structure was markedly influenced thinning, fungal remained stable. Importantly, changes composition diversity had minimal impacts processes, whereas such as pH, organic carbon content, forms, were identified primary drivers.

This study examines the responses of soil organic carbon (SOC) pools and their components to agricultural water drainage in paddy fields, with a focus on wetland–paddy field ecotone Xingkai Lake, transboundary lake shared by China Russia. Field investigations targeted three representative wetland vegetation types: Glyceria spiculosa (G), Phragmites australis (P), Typha orientalis (T), across durations ranging from 0 over 50 years. SOC fractions, including light fraction (LFOC), heavy (HFOC), dissolved (DOC), microbial biomass (MBC), were systematically analyzed. The results revealed that T P wetlands steadily increased duration, whereas those G exhibited fluctuating pattern. dynamics primarily driven LFOC, while MBC displayed species-specific variations. Correlation analyses structural equation modeling (SEM) demonstrated physicochemical properties, such as total nitrogen moisture content, exerted stronger influence fractions than biomass. Overall, drawdown significantly altered dynamics, distinct observed types ages. provides critical data theoretical insights for optimizing sequestration hydrological management systems.
