Innovation in environmental sustainability: carbon credits with proof of reserve on rural properties according to the standards of regulated markets

Marcos Ferronato, Ana Carolina Clivatti Ferronato, Miguel Angel Uribe Opazo

Published: 2025-05-07
Subjects: Agriculture

Farms are increasingly recognized as carbon sinks with significant potential to mitigate climate change. This study documents how farms can become positive climate assets by using portable sensors, satellite imagery, blockchain, and AI to quantify and monetize carbon removal. This technological integration enables the issuance of traceable and secure carbon credits, promoting sustainable land use [...]

Nitrogen Mineralization of Cover Crop Residue Depends on Carbon to Nitrogen Ratio and Soil Temperature

Anna Gomes, Diego Gutierrez, Sierra Castaneda, et al.

Published: 2025-05-06
Subjects: Agriculture

Groundwater nitrate contamination is largely attributed to fertilizer and intensive livestock manure inputs in agricultural systems. California’s Salinas Valley is an area where state policy is aiming to reduce nitrate leaching. Non-legume winter cover crops can help decrease nitrate leaching by scavenging residual soil nitrogen (N) during winter fallow periods following the cropping season. [...]

Assessing the effectiveness of irrigator-driven groundwater conservation programs to drought: a case study of the northwestern Kansas Local Enhanced Management Areas

Wayne Ndlovu, Sam Zipper, Timothy Foster

Published: 2025-04-08
Subjects: Agriculture, Hydrology, Natural Resources and Conservation, Natural Resources Management and Policy, Sustainability, Water Resource Management

Groundwater pumping for irrigation has led to significant decreases in groundwater levels in agricultural areas around the world, including the U.S. High Plains Aquifer. Here, we used a process-based corn and sorghum crop model, AquaCrop, to assess the effectiveness of different irrigation management strategies during a synthetic multi-year drought. We focused on the Groundwater Management [...]

Comprehensive Assessment of Flood Risk and Community Impact of Concentrated Animal Feeding Operations in Iowa

Ugur Satilmis, Jerry Mount, Adem Bayram, et al.

Subjects: Agriculture, Civil and Environmental Engineering, Civil Engineering, Engineering, Environmental Engineering, Hydraulic Engineering, Life Sciences

Flooding presents a significant risk to Concentrated Animal Feeding Operations (CAFOs), especially in regions increasingly affected by extreme weather events. This study uses advanced geospatial analysis techniques to assess the environmental and economic vulnerabilities of 12,703 CAFOs across Iowa, United States. We focused on the exposure of CAFOS to 100-year and 500-year floodplains, [...]

The role of information in shaping the emerging agricultural soil carbon market

Lisette Phelan, Guy Ziv, Pippa J Chapman

Published: 2025-01-23
Subjects: Agriculture, Life Sciences

The agricultural soil carbon market that has emerged in recent years is widely regarded as a promising opportunity for farmers in the Global North and South, enabling them to generate carbon credits and derive a source of income from the adoption of alternative land management practices which contribute to climate change mitigation by increasing soil carbon sequestration and/or reducing [...]

Global industrial disruption following nuclear war

Simon Blouin, Florian Ulrich Jehn, David Denkenberger

Published: 2024-12-05
Subjects: Agriculture, International and Area Studies, Other Geography, Risk Analysis

Nuclear war poses catastrophic risks not only through its immediate effects and potential nuclear winter, but also through the disruption of industrial production on which modern civilization depends. In this study we estimate the reduction in global industrial output following a US-Russia nuclear war, as well as a more limited India-Pakistan exchange, by combining geospatial analysis with [...]

The State of Global Catastrophic Risk Research: A Bibliometric Review

Florian Ulrich Jehn, John-Oliver Engler, Constantin W. Arnscheidt, et al.

Published: 2024-11-30
Subjects: Agriculture, Biodiversity, Environmental Sciences, Environmental Studies, Food Science, Geography, Other Life Sciences

The global catastrophic risk (GCR) and existential risk (ER) literature focuses on analysing and preventing potential major global catastrophes including a human extinction event. Over the past two decades, the field of GCR/ER research has grown considerably. However, there has been little meta-research on the field itself. How large has this body of literature become? What topics does it cover? [...]

Exposure to compound climate hazards transmitted via global agricultural trade networks

Patrick W Keys, Elizabeth A Barnes, Noah S Diffenbaugh, et al.

Published: 2024-11-16
Subjects: Agriculture, Climate, Environmental Studies, Risk Analysis

Compound climate hazards, such as co-occurring temperature and precipitation extremes, substantially impact people and ecosystems. Internal climate variability combines with the forced global warming response to determine both the magnitude and spatial distribution of these events, and their consequences can propagate from one country to another via many pathways. We examine how exposure to [...]

Sensing the dynamic nature of fragmented croplands in India through earth observation: a comprehensive review

Subhajit Bandopadhyay, Sourav Dey, Latika Grover, et al.

Published: 2024-11-10
Subjects: Agriculture, Earth Sciences, Environmental Sciences, Food Science, Geography, Nature and Society Relations, Physical and Environmental Geography, Remote Sensing, Spatial Science

Fragmentation or the breakdown of landholdings to smaller parcels has an adverse impact on crop yields and productivity because of its uneconomic operational sizes. This comprehensive review reflects the insights into the complex dynamics of small landholding (SLs) in India by leveraging earth observation (EO) based sensing technology through synthesizing existing literature, methodologies and [...]

Unveiling Year-Round Cropland Cover by Soil-Specific Spectral Unmixing of Landsat and Sentinel-2 Time Series

An event such as a large volcanic eruption, nuclear winter or asteroid/comet impact has the potential to seriously reduce incoming sunlight, impacting both the global climate and conventional crop yields. This could have catastrophic impacts on human nutrition, unless the food system can adapt. One possible answer is seaweed, where growth is projected to be less impacted (or even enhanced) by the [...]
