Abstract Natural revegetation, afforestation, and lignocellulosic crops for bioenergy, possibly coupled with a developing technology like carbon capture storage, are the most common land-based climate change mitigation options. However, they can compete land threaten food security or nature conservation. Using abandoned cropland their deployment minimize these risks, but associated potentials unclear. Here, we compare alternative options by integrating historical future (up to 2050) site-specific biomass yields life-cycle emissions. Considering natural revegetation in biodiversity priority areas different measures remaining achieve potential of 0.8–4.0 GtCO 2 -equivalents yr −1 (2–11% 2021 global CO emissions). Afforestation generally provides larger benefits than bioenergy storage delivers highest locations. Overall, results offer refined estimates from highlight opportunities context-specific measures.

Abstract Traditional fertilizers are highly inefficient, with a major loss of nutrients and associated pollution. Alternatively, biochar loaded phosphorous is sustainable fertilizer that improves soil structure, stores carbon in soils, provides plant the long run, yet most biochars not optimal because mechanisms ruling properties poorly known. This issue can be solved by recent developments machine learning computational chemistry. Here we review phosphorus-loaded emphasis on chemistry, learning, organic acids, drawbacks classical fertilizers, production, phosphorus loading, release. Modeling techniques allow for deciphering influence individual variables biochar, employing various supervised models tailored to different types. Computational chemistry knowledge factors control binding, e.g., type compound, constituents, mineral surfaces, binding motifs, water, solution pH, redox potential. Phosphorus release from controlled coexisting anions, adsorbent dosage, initial concentration, temperature. Pyrolysis temperatures below 600 °C enhance functional group retention, while 450 increase plant-available phosphorus. Lower pH values promote release, higher hinder it. Physical modifications, such as increasing surface area pore volume, maximize adsorption capacity biochar. Furthermore, acid affects low molecular weight acids being advantageous utilization. Lastly, biochar-based 2–4 times slower than conventional fertilizers.

Abstract. Biogenic volatile organic compounds (BVOCs) are emitted in large quantities from the terrestrial biosphere and play a significant role atmospheric gaseous aerosol compositions. Secondary aerosols (SOAs) resulting BVOC oxidation affect radiation budget both directly, through scattering absorption of sunlight, indirectly, by modifying cloud properties. Human activities have extensively altered natural vegetation cover, primarily converting forests into agricultural land. In this work, global chemistry–climate model, coupled with dynamic was employed to study impacts perturbing human-induced land use change, thereby exploring changes emissions burden. A scheme implemented constrain tree plant functional type (PFT) cover based on transformation fraction maps year 2015. Two scenarios were evaluated: (1) one comparing present-day which includes areas deforested for crops grazing land, potential (PNV) simulated (2) an extreme reforestation scenario is restored levels. We find that, compared PNV scenario, deforestation results 26 % reduction emissions, decreases biogenic SOA (bSOA) burden 0.16 Tg (a decrease 29 %), while total (OA) 0.17 9 %). On other hand, suggests increase 22 %, increases bSOA 0.11 OA 0.12 – 6 respectively.

ABSTRACT Given the extent of recent land use‐land cover changes and consequences for hydrological effects, it is important to capture role that plays in model conceptualization. This need amplified under a changing climate, as sensitivity catchments climate change can vary depending on cover. Traditionally, calibration has prioritized parameter adjustment rather than enhancing representation processes. practice—though useful improving fit—can lead misinterpretations, especially when simulating varying conditions. While airborne satellite remote sensing technologies now allow frequent, large‐scale monitoring surface parameters, their spatiotemporal complexities remain underutilized models. By analyzing conceptualizations related processes within models, this paper reviews progress current state modeling approaches discusses future research needs directions. The path ahead one embracing technological advancements methodological rigor, focusing representing multifaceted reality.

Overpopulation’s central role in environmental degradation is intermittently challenged. This article assesses the impact of mounting demographic pressures on six critical global sustainability challenges: deforestation, climate change, biodiversity loss, fishery depletion, water scarcity, and soil degradation. By synthesizing findings from hundreds peer-reviewed studies, offers a comprehensive review effects expanding human populations most pressing current problems. Although rate population growth worldwide slowing, numbers are expected to continue increasing Earth until end century. Current research confirms that overpopulation causes substantial potentially irreversible impacts cannot be ignored if international policy effective.

Understanding changes of ecosystem services and their influencing factors is crucial for more sustainable management conservation nature contributions to people, especially in regions suffering high pressure from climate change human activities, such as the Nordic countries. In this study, we assess multiple Denmark, Finland, Norway, Sweden. We analyze habitat quality, sediment retention, water yield, carbon sequestration, crop roundwood production between 2003 2018. The relationships main (temperature, precipitation, elevation, population, livestock, land use change) are assessed by means Spearman's correlation coefficient a new method that unravels synergies or tradeoffs at grid level. Given importance forest study region, an advanced cover dataset includes maps harvest produced used basis analysis. Results show large during period spatial variations. Overall, quality decreased, sites affected agricultural production. Water yield retention increased due higher precipitation (mainly Norway). Higher temperature have generally sequestration provisioning services. relationship potential differs across space. There 10 out 15 pairs predominantly tradeoff relationship, while rest shows synergy. general, our results monitor understand drivers changes, so design resource strategies can secure long-term delivery
