Short-term warming supports mineral-associated carbon accrual in abandoned croplands

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Янв. 2, 2025

Effective soil organic carbon (SOC) management can mitigate the impact of climate warming. However, response different SOC fractions to warming in abandoned croplands remains unclear. Here, categorizing into particulate and mineral-associated (POC MAOC) with physical fractionation, we investigate responses POC MAOC content temperature sensitivity (Q10) through a 3-year situ experiment (+1.6 °C) across 12 sites China (latitude: 22.33–46.58°N). Our results indicate that unchanged while significantly increases under changes are mainly influenced by root biomass microbial necromass changes, respectively. The Q10 is lower than regardless or control treatment, suggesting represents most persistent least vulnerable fraction within SOC. Collectively, sequestration stable be enhanced short-term Natural recovery generally benefits accrual croplands, but on this ecosystem authors showed enhances these lands.

Potential of Abandoned Agricultural Lands for New Photovoltaic Installations

Sustainability, Год журнала: 2025, Номер 17(2), С. 694 - 694

Опубликована: Янв. 17, 2025

Decarbonization strategies aim at increasing renewable energy source (RES) capacity, including new photovoltaic (PV) systems. Utility-scale PV installations are often placed in agricultural areas, resulting a reduction land and affecting the environment. To balance policies, development should not limit purposes, allowing sustainable exploitation under specific technological environmental conditions, particularly areas of actual or potential abandonment. Studying abandonment is complex due to its multifaceted nature, lack clear definition, challenges acquiring cartographic data. This study introduces compares two methodologies identify abandoned aiming delineate macro-areas examine patterns for conversion use, with focus on Toscana, region (NUTS-2) central Italy, which has experienced cropland unrelated urbanization. The first, simplified approach analyses cover changes from 2000 2018, while second method provides more detailed detection by means medium spatial resolution satellite imagery Harmonized Landsat Sentinel-2 dataset. A Random Forest classifier combined Object-Based Image Analysis (OBIA) applied data map annual active/non-active croplands. Annual maps then validated trajectory-based detect methodology can help providing spatially timely meaning estimates be recovered purposes promote growth

Mapping the Spatiotemporal Dynamics of Cropland Abandonment and Recultivation across the Yangtze River Basin

Remote Sensing, Год журнала: 2024, Номер 16(6), С. 1052 - 1052

Опубликована: Март 15, 2024

Whether China can achieve the United Nations’ Sustainable Development Goals (SDGs) largely depends on ability of main food-producing areas to cope with multiple land use change challenges. Despite fact that Yangtze River basin is one key regions for China’s food security, spatiotemporal dynamics cropland abandonment and recultivation remain unexplored in this region. The present study assesses evolution agricultural system within between 2000 2020 by mapping using MODIS time series cover products. results highlight a widespread process (i.e., 10.5% total area 2020), predominantly Western Sichuan, Eastern Yunnan, Central Jiangxi. Although 70% abandoned situated slopes less than 5°, highest rates are mountainous regions. However, 2020, 74% had been recultivated at least once, whereas half croplands got three years their initial abandonment. Hence, as first studies unravels complex interaction explicit context, it offers (i) scientists novel methodological framework assess issues across large geographical entities, (ii) policy-makers new insights support sustainable transition sector.
