The research analyzes the conflict between groundwater extraction in the Río Cuchujaqui watershed and the conservation goals of the Sierra de Álamos protected area, concluding that institutional mandate conflicts have blocked the creation of a conservation-focused water management program.

The study analyzes the expansion of timber plantations, primarily Pinus radiata, in south-central Chile from 1975 to 2007. Using satellite imagery and autologistic regressions, the research finds that plantations grew from 5.5% to 42.4% of the landscape. Early expansion (1975–1990) was strongly linked to forest-suitable soils, steep slopes, proximity to cities, and corporate landholdings. The study highlights that a significant portion of this expansion resulted from clearing secondary native forests, contributing to deforestation and biodiversity loss.

The study utilized the Standardized Precipitation Evapotranspiration Index (SPEI) from 98 stations and GIS interpolation to identify extreme climate events in the Semi-Arid Pampean Region from 2000 to 2012. It identified 2001 as a wet year and 2009 as a dry year, concluding that the Spline interpolation method is optimal for characterizing these events in the region.

The research presents a simplified approach to modeling aquifer behavior using basic geometry and trigonometry rather than complex differential equations. By analyzing static water levels at three specific dates, the authors were able to identify areas of the Cuauhtemoc aquifer characterized by increased extraction and areas experiencing considerable recharge.

The study analyzed the impact of precipitation variability on the surface area of Paso de las Piedras and La Picasa from 1981 to 2012. It found that extreme precipitation events caused significant but differing increases in water area: 1.1 km2 for Paso de las Piedras in 2005 and 174.9 km2 for La Picasa in 2002. Additionally, the study noted that Reanalysis data did not show a linear relationship with in situ measurements.

The study analyzed chlorophyll concentrations from 1997 to 2017 using SeaWiFS and MODIS Aqua data across four Large Marine Ecosystems (LMEs). It found significant increases in chlorophyll concentrations in large portions of the Patagonia (PLME) and Humboldt (HLME) ecosystems, while increases in the South Brazil (SBLME) and Pacific Coastal Central America (PCACLME) ecosystems were limited to smaller regions.

The study identifies a strong correlation between active fire anomalies in the Brazilian Amazon and deforestation, noting that the 2019 crisis was particularly severe in the states of Acre, Amazonas, and Roraima.

The study identifies three primary areas of endemism in the Magellan region based on the distribution of Amphipoda, Copepoda, and Euphausiacea: Chiloé, the Atlantic coast, and Fueguia. The findings suggest that the Atlantic coast and Fueguia areas do not align strictly with previously defined provinces and provide new biogeographic insights for marine protected areas including Burdwood Bank, Yaganes, and the Diego Ramírez-Drake Passage.

The report finds that approximately 7% of energy transition mineral mines overlap with Key Biodiversity Areas, affecting an area roughly twice the size of Belgium. While this impact is smaller than that of fossil fuel extraction, the report warns of significant risks to biodiversity and Indigenous rights, advocating for nature-positive spatial planning, circular economy practices, and responsible mining standards to mitigate these harms.

The report details the compilation of pilot ecosystem accounts for Kaduna and Nasarawa states in Nigeria between 2015 and 2020. Using the SEEA-EA framework and ARIES AI technology, the study estimated biophysical supply for climate regulation (carbon storage), soil retention, crop production, pollination, and water supply. Findings indicate that while total carbon stocks and soil retention remained relatively stable, there were significant shifts in land cover, including an increase in deciduous broadleaf forests and a loss of shrublands. The report emphasizes the lack of local geo-referenced data and the need for an institutional framework to support independent national environmental accounting.

The ADAPTE project uses GIS to map the intersection of air pollution, extreme weather, and social vulnerability in Latin American cities. Findings indicate that PM10 and NOx levels in Mexico City, Santiago, and Bogota significantly exceed WHO standards. The research highlights that respiratory and cardiovascular mortality risks vary by city, season, and age group, with children in Bogota showing higher respiratory risk during cold seasons and elderly populations showing higher cardiovascular risk during the same period.

The paper argues that biomass energy projects, framed as climate change mitigation, serve as a mechanism for 'energy grabbing' and the reconcentration of land control by Perhutani. Through case studies in Sukabumi, Grobogan, and Bojonegoro, it demonstrates how the classification of land as 'unproductive' or 'critical' is used to dispossess local farmers and transform them into low-paid laborers. The study finds that the promotion of gamal and kaliandra as 'flex trees' restricts community access to essential resources like firewood and fodder, while triggering localized resistance and criminalization of farmers.

The BEST-P project investigates the relationship between land cover dynamics and ecosystem services in southern South America, specifically focusing on carbon and water regulation. Using remote sensing and field studies, the project has quantified the impacts of deforestation and afforestation in the Chaco region, analyzed the influence of different landholder types on conservation, and developed tools to integrate biophysical and human dimensions into territorial planning. The initiative also provides evidence to support legal actions against illegal deforestation in Argentina by demonstrating cross-province climatic impacts.

The project assesses how conservation policies, specifically payments for environmental services and protected areas, impact tropical dry forest deforestation in Costa Rica and Brazil. It highlights that conventional evaluations often overestimate the success of protected areas by failing to control for biophysical and socioeconomic factors, such as slope and proximity to roads. Findings indicate that the location of protected areas is critical, with higher deforestation prevention occurring near urban centers and national roads compared to remote or steep areas.

The authors propose a streamlined framework to detect and map extreme events—specifically heatwaves, droughts, and floods—by selecting optimal environmental indicators and thresholds. Tested in Sweden using data from 1922–2021, the framework identified increasing occurrences of heatwaves and floods in large areas, while finding no significant trend for droughts. The study also identified compound hazard hotspots in northern Sweden, where drought-heatwave and drought-flood events are positively correlated between June and August.

Agri-PV, the simultaneous use of land for food production and solar electricity, offers significant potential for Central Europe to increase renewable energy generation and improve farmer livelihoods. Analysis shows that Czechia, Hungary, Poland, and Slovakia could deploy 180 GW of agri-PV, potentially tripling the region's annual renewable electricity production. While agri-PV can increase yields for certain crops like berries by up to 16%, it can also offset yield losses in shade-sensitive crops like wheat through electricity revenues. Despite this, Czechia is currently the only country in the region with agri-PV legislation, and the report recommends that other Central European governments introduce regulations to secure CAP subsidies and incentivize the transition.

Climate Central analyzed the urban heat island (UHI) index across 65 major U.S. cities, finding that 68% of the 50 million residents in these cities live in areas where the built environment increases temperatures by 8°F or more. The study identifies albedo, green space, and population density as the primary drivers of this effect. It also highlights a link between historical redlining and current heat disparities, noting that in 84% of 179 analyzed cities, historically redlined areas experience hotter summers than non-redlined areas.

The report evaluates a proposed land restoration project in Burkina Faso using nature-based infrastructure (NBI) to address severe land degradation and climate-driven displacement. The analysis finds that NBI outperforms grey infrastructure, offering a return of USD 14.8 in benefits for every USD 1 invested, while providing significant carbon storage and reducing conflict by stabilizing rural livelihoods.

A Union of Concerned Scientists analysis of non-transportation BIL awards in California from fiscal years 2022 and 2023 indicates that local investments are likely falling short of Justice40 goals. Depending on the screening tool used, only 9.4% to 18.2% of analyzed local funding is flowing to designated disadvantaged communities. The report highlights significant data gaps, particularly regarding statewide formula funding, and recommends a transparent, unified tracking system and a clear definition of 'benefits' to ensure equitable infrastructure spending.

The document describes a spatial and recipient-based analysis of federal Bipartisan Infrastructure Law (BIL) funding in California from October 1, 2021, to September 30, 2023. It compares two environmental justice screening tools—the federal Climate and Economic Justice Screening Tool (CEJST) and California's SB 535—to identify disadvantaged communities. The analysis focuses on non-transportation grants, as transportation spending accounted for over 88 percent of the total obligated spending ($16.07 billion) and is tracked separately by the state. The authors highlight significant data limitations in USASpending.gov, including agency non-reporting and inaccuracies in 'place of performance' fields, which may hinder the tracking of Justice40 goals.
