Potential of land-based climate change mitigation strategies on abandoned cropland

Communications Earth & Environment, Journal Year: 2023, Volume and Issue: 4(1)

Published: Feb. 16, 2023

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.

Machine learning and computational chemistry to improve biochar fertilizers: a review

Environmental Chemistry Letters, Journal Year: 2023, Volume and Issue: 21(6), P. 3159 - 3244

Published: Aug. 17, 2023

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.

Land Use‐Land Cover and Hydrological Modeling: A Review

Wiley Interdisciplinary Reviews Water, Journal Year: 2025, Volume and Issue: 12(2)

Published: March 1, 2025

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.

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.
