The neglected role of abandoned cropland in supporting both food security and climate change mitigation

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Sept. 28, 2023

Despite the looming land scarcity for agriculture, cropland abandonment is widespread globally. Abandoned can be reused to support food security and climate change mitigation. Here, we investigate potentials trade-offs of using global abandoned recultivation restoring forests by natural regrowth, with spatially-explicit modelling scenario analysis. We identify 101 Mha between 1992 2020, a capability concurrently delivering 29 363 Peta-calories yr

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.

Cropland abandonment between 1986 and 2018 across the United States: spatiotemporal patterns and current land uses

Environmental Research Letters, Journal Year: 2024, Volume and Issue: 19(4), P. 044009 - 044009

Abstract Knowing where and when croplands have been abandoned or otherwise removed from cultivation is fundamental to evaluating future uses of these areas, e.g. as sites for ecological restoration, recultivation, bioenergy production, other uses. However, large uncertainties remain about the location time cropland abandonment how this process availability associated lands vary spatially temporally across United States. Here, we present a nationwide, 30 m resolution map throughout period 1986–2018 conterminous States (CONUS). We mapped annual layers created in Google Earth Engine Landsat imagery using an automated classification method training data U.S. Department Agriculture Cropland Data Layer. Our has overall accuracies 0.91 0.65 abandonment, respectively. From 1986 2018, 12.3 (±2.87) million hectares (Mha) were CONUS, with areas greatest change over Ogallala Aquifer, southern Mississippi Alluvial Plain, Atlantic Coast, North Dakota, northern Montana, eastern Washington state. The average nationwide area our study was 0.51 Mha per year. Annual peaked between 1997 1999 at rate 0.63 year −1 , followed by continuous decrease 0.41 2009–2011. Among croplands, 53% (6.5 Mha) changed grassland pasture, 18.6% (2.28 shrubland forest, 8.4% (1.03 wetlands, 4.6% (0.56 non-vegetated lands.

Spatiotemporal Patterns and Determinants of Cropland Abandonment in Mountainous Regions of China: A Case Study of Sichuan Province

Cropland abandonment (CA) is an increasingly severe global issue, with significant implications for achieving the Sustainable Development Goal of Zero Hunger. In China, widespread CA particularly evident in remote mountainous regions. However, rugged terrain and highly fragmented cropland pose challenges mapping abandoned high precision using sensing technology. Moreover, result multi-level factors, yet previous studies have primarily analyzed its driving factors from a single level, leading to lack comprehensive understanding underlying mechanisms. We took Sichuan Province, located regions Western as case study, utilizing satellite-derived high-precision maps reveal spatiotemporal patterns CA. Additionally, we employed hierarchical linear model explore determinants their interactions at both county municipal levels. The results indicate that rate decreased continuously 6.75% 2019 4.47% 2023, exhibiting spatial clustering. High-value clusters were predominantly concentrated western areas, hotspots exhibited general migration trend northeast southwest. Furthermore, found influenced by 61% 39% variance being explained levels, respectively. agglomeration index (AI) key determinant Digital Elevation Model (DEM) distance roads also playing roles.
