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

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 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.

Bioenergy expansion is present in most climate change mitigation scenarios. The associated large land use changes have led to concerns on how bioenergy can be sustainably deployed. Promising win-win strategies include the production of perennial crops recently abandoned cropland or prone degradation, as typically reduce soil erosion rates. Natural vegetation regrowth an alternative nature-based solution that also co-deliver negative emissions and other environmental benefits. In this study, we explore potential deploy Nordic countries (Norway, Sweden, Finland, Denmark) threatened by compare achievable benefits with natural regrowth.
