CONTEXT The agricultural expansion and intensification modify the structure functioning of ecosystems, which alter their capacity to provide ecosystem services (ES). An adequate analysis these changes requires an exhaustive characterization land use cover. In Rio de La Plata Grassland (RPG), most characterizations are limited in terms spatial or conceptual resolution since they generally differentiate coarse classes, such as winter summer crops instead crop types, at more than 30 meters. OBJECTIVE this work, we propose map types cropping systems one productive areas RPG assess effects on services. METHODS Combine remote sensing data based optical microwave sensors provided by Sentinel 1 2 satellites (10 meters) systems. Also, used Landsat 8 images characterize albedo, Land Surface Temperature (LST) evapotranspiration (ET) analyze environmental impacts agriculture. Furthermore, estimate NDVI (a proxy primary production) Ecosystem Services Supply Index (ESSI), a synoptic indicator that estimates provision regulating ES related water carbon dynamics annual dynamics. RESULTS AND CONCLUSIONS We identified 14 with overall precision between 0.85 0.95. Winter were better crops. Compared native grasslands, different generated increase albedo surface temperature while tended be higher had per year. productivity (NDVI) supply (ESSI) variables showed greatest variability. Schemes cover pastures would allow maintaining functioning, suggest need preserve expand area covered production keep soil for much SIGNIFICANCE This work allowed us evaluate effect supply, information interest future design, planning implementation sustainable development schemes.

In southern Europe, land abandonment and an unbalanced investment toward fire suppression instead of prevention has gradually increased wildfire risk, which calls for a paradigm change in management policies. Here we combined scenario analysis, landscape modelling, economic tools to identify land-use policies would reduce the expected wildfire-related losses Transboundary Biosphere Reserve 'Gerês-Xurés' (Spain-Portugal). To do so, applied least-cost-plus-net-value-change approach estimated net changes damages based on their implications 2010–2050 period five ecosystem services: agriculture, pasture, timber, recreation climate regulation. Four scenarios were considered: (1) Business as Usual (BAU); (2) fire-smart, fostering more fire-resistant (less flammable) and/or fire-resilient landscapes (fire-smart); (3) High Nature Value farmlands (HNVf), wherein extensive agriculture is reversed; (4) combination HNVf fire-smart. best cost savings, but it generates lowest present value societal benefits from fact, most efficient with discounted costs services + fire-smart scenario, also savings agricultural expansion, lead significant reduction timber recreational benefits.

Wildfires significantly disturb ecosystems by altering forest structure, vegetation ecophysiology, and soil properties. Understanding the complex interactions between topographic climatic conditions in post-wildfire recovery is crucial. This study investigates interplay topography, climate, burn severity, years after fire on across dominant land cover types (evergreen forest, shrubs, grassland) Pacific Northwest region. Using Moderate Resolution Imaging Spectroradiometer (MODIS) data, we estimated calculating incremental Enhanced Vegetation Index (EVI) change during post-fire years. A machine learning algorithm, random (RF), was employed to map relationships input features (elevation, slope, aspect, precipitation, temperature, fire) target (incremental EVI recovery) for each type. Variable importance analysis partial dependence plots were generated understand influence of individual features. The observed predicted values showed good matches, with R2 0.99 training 0.89–0.945 testing. found that climate variables, specifically precipitation most important overall, while elevation played significant role among factors. Partial revealed lower tended cause a reduction varying temperature ranges types. These findings can aid developing targeted strategies management, considering responses different topographic, climatic, severity

As wildfires become more frequent and severe in the face of global environmental change, it becomes crucial not only to assess, prevent, suppress them but also manage aftermath effectively. Given temporal interconnections between these issues, we explored concept “wildfire science loop”—a framework categorizing wildfire research into three stages: “before”, “during”, “after” wildfires. Based on this partition, performed a systematic review by linking particular topics keywords each stage, aiming describe one quantify volume published research. The results from our identified substantial imbalance landscape, with post-fire stage being markedly underrepresented. Research focusing is 1.5 times (or 46%) less prevalent than that “before” 1.8 77%) “during” stage. This discrepancy likely driven historical emphasis prevention suppression due immediate societal needs. Aiming address overcome imbalance, present perspectives regarding strategic agenda enhance understanding processes outcomes, emphasizing socioecological impacts management recovery multi-level transdisciplinary approach. These proposals advocate integrating knowledge-driven burn severity ecosystem mitigation/recovery practical, application-driven strategies policy development. supports comprehensive spans short-term emergency responses long-term adaptive management, ensuring landscapes are better understood, managed, restored. We emphasize critical importance “after-fire” breaking negative planning cycles, enhancing practices, implementing nature-based solutions vision “building back better”. Strengthening balanced focused will ability close loop involved improve alignment international agendas such as UN’s Decade Ecosystem Restoration EU’s Nature Law. By addressing can significantly restore ecosystems, resilience, develop suited challenges rapidly changing world.

Abstract Background Climate change is altering the fire regime and compromising post-fire recovery of vegetation worldwide. To understand factors influencing cover restoration, we calculated in 200,000 hectares western Mediterranean forest burned by 268 wildfires over a 27-year period (1988–2015). We used time series Tasseled Cap Transformation Brightness (TCTB) spectral transformation Landsat imagery to calculate recovery. Then, quantified importance main drivers (climate, severity, topography) along an aridity gradient (semi-arid, sub-humid, humid) using Random Forest models. Results In most models (99.7%), drought duration was important factor, negatively affecting especially extremes gradient. Fire severity second factor for recovery, with its effect varying gradient: there positive relationship between sub-humid humid areas, while semi-arid areas showed opposite pattern. Topographic variables were least driver had marginal on Additionally, exhibited low mean rate, indicating limitations short-term after fire. Conclusions Our study highlights key role that plays basin and, particularly, forests located climatically extreme areas. The results suggest predicted increase coupled higher frequency intensity large fires may modify structure composition ecosystems. analysis provides relevant information evaluate design adaptive management strategies hotspots

Climate-driven changes in fire regimes are expected across the pan-Arctic region. Trends arctic fires thought to be generally increasing; however, mapping region is far from comprehensive or systematic. We developed a new detection workflow and built dataset of unrecorded tundra Canada using Landsat data. reference spectral indices previously mapped northern train Random Forest model for detecting between 1986 2022. In addition, we used time series information each pixel reduce false positives narrow large search space down finite set regions that had experienced changes. found 209 undetected Arctic sub-Arctic regions, increasing burned area by approximately 30%. The median size was small, with roughly 3/4 being <100 ha size. majority newly detected (69%) did not have satellite-derived hotspots associated them. presented here commission error-free can viewed as future analyses. Moreover, improvements updates will leverage these data improve outlined here, particularly small low-severity fires. These facilitate broader analyses examine trends environmental drivers Such could begin untangle mechanisms driving heterogeneous responses climate observed Circumpolar North.
