Agricultural technology adoption is a critical driver of sustainable development, particularly in developing regions where agriculture plays a pivotal role in food security and livelihoods. This study combines network analysis, including causal loop diagrams (CLD), with centrality metrics, to uncover key leverage points within the system where targeted interventions can yield significant impacts [...]

Quantification of Water Distribution in California: A Case Study for Other Regions in the World

Amrith Srinath Gunasekara

Published: 2024-02-02
Subjects: Agriculture

Data for water distribution by the urban sector, environment, and agriculture across the world is not readily available, publicly accessible, or quantitatively evaluated. It is critical for any society to define and transparently account for regional water distribution in a state or country to facilitate accurate information sharing with the public. Water use in California has been criticized for [...]

Bayesian network modelling of phosphorus pollution in agricultural catchments with high-resolution data

Camilla Negri, Per-Erik Mellander, Nicholas Schurch, et al.

Published: 2024-01-11
Subjects: Agriculture, Biochemistry, Environmental Monitoring, Statistical Models

A Bayesian Belief Network was developed to simulate phosphorus (P) loss in an Irish agricultural catchment. Septic tanks and farmyards were included to represent all P sources and assess their effect on model performance. Bayesian priors were defined using daily discharge and turbidity, high-resolution soil P data, expert opinion, and literature. Calibration was done against seven years of daily [...]

Probabilistic assimilation of optical satellite data with physiologically based growth functions improves crop trait time series reconstruction

Lukas Valentin Graf, Flavian Tschurr, Achim Walter, et al.

Published: 2023-11-13
Subjects: Agriculture

A sound understanding of plant growth is critical to maintaining future crop productivity under ongoing climate change. Remotely sensed time series of crop functional traits from optical satellite imagery are an invaluable tool for deriving appropriate management practices that facilitate risk mitigation and increase the resilience of agroecosystems. However, the availability of imagery is [...]

The Nexus between Access to Agricultural Extension Services and Adoption of Sustainable Soil Conservation Practices in Limu Districts, Oromia, Ethiopia

Subjects: Agriculture

Provision of agricultural extension service is the primary mechanism that increases smallholder farmer’s adoption of sustainable soil conservation practices. This study was, therefore, attempted to examine the nexus between access to agricultural extension services and the adoption of sustainable soil conservation practices in western oromia in the case Limu districts. Data was collected from [...]

Global trade and the resilience of food supply to extreme weather exposure

Daniel Patrick Bebber, Carole Dalin, Emma Littleton, et al.

Published: 2023-08-31
Subjects: Agriculture, Physical and Environmental Geography, Sustainability

Climate change is increasing the risk of extreme weather events, potentially threatening crop yields and global food security. A key benefit of international free trade is risk sharing, because global aggregate production is more stable than that of individual countries which may be adversely affected by extremes. Here we test the hypothesis that diverse sourcing of crops from multiple trading [...]

Information Sharing: The Missing Ingredient in Science, Technology and Innovation Policy of Pakistan-Agriculture Perspective

Asmat Ali, Munir Ahmad, Mobushir Riaz Khan

Published: 2023-08-22
Subjects: Agriculture, Food Science, Geographic Information Sciences, Remote Sensing, Spatial Science

The purpose of this paper is to focus on the important role of information sharing in advancing innovation that is presently missing in National Science, Technology and Innovation (STI) Policy of Pakistan approved in 2012. Information is a key resource for making innovations in science, technology and policies. Like other countries of the world, almost all government departments in Pakistan [...]

Social Vulnerability and Climate Risk Assessment for Agricultural Communities in The United States

Tugkan Tanir, Enes Yildirim, Celso M. Ferreira, et al.

Published: 2023-08-18
Subjects: Agriculture, Civil and Environmental Engineering, Environmental Indicators and Impact Assessment, Geographic Information Sciences, Physical and Environmental Geography, Risk Analysis, Spatial Science

Floods and droughts significantly affect agricultural activities and pose a threat to food security by subsequently reducing agricultural production. The impact of flood events is distributed disproportionately among agricultural communities based on their socio-economic fabric. Understanding climate-related hazards is critical for planning mitigation measures to secure vulnerable communities. [...]

Experimental results, integrated model validation, and economic aspects of agrivoltaic systems at northern latitudes

Pietro Elia Campana, Bengt Stridh, Torsten Hörndahl, et al.

Published: 2023-07-31
Subjects: Agriculture, Other Mechanical Engineering

Agrivoltaic systems, which allow the coexistence of crop and electricity production on the same land, are considered an integrated water-energy-food nexus solution to allow the simultaneous attainment of conflicting Sustainable Development Goals. This study aims to analyse experimental results on ley grass yield and quality response to shadings in the first agrivoltaic system in Sweden and [...]

Sustainable irrigation reduces arsenic bioavailability in fluvio-alluvial soils promoting microbial responses, high rice productivity and economic profit

Arnab Majumdar, Munish Kumar Upadhyay, Biswajit Giri, et al.

Published: 2023-07-26
Subjects: Agricultural Science, Agriculture, Agronomy and Crop Sciences Life Sciences, Biodiversity, Environmental Studies, Microbiology

Minimizing arsenic (74.92As33) loading into rice plants, we suggest adopting alternating wetting and drying (AWD) irrigation as a sustainable water management strategy allowing greater silicon (28.08Si14) availability. This two-year field-based project is the first report on AWD's impact on As-Si distribution in fluvio-alluvial soils of the entire Ganga valley (24 study sites divided into six [...]

Regenerative Agriculture the Veganic Way: A Seven-year Research Study in Increasing Soil Organic Matter (SOM) and Crop Yields

Jimmy Videle, Mona Seymour, Nicholas Carter

Published: 2023-07-15
Subjects: Agriculture

Agriculture is a major contributor to greenhouse gas (GHG) emissions and biodiversity loss, mostly through deforestation for the cultivation of animal feeds; enteric fermentation from ruminants like cattle, fertilizers and manure; and soil degradation from intensive farming practices. There is currently a push to transform our farming systems to attempt to alleviate the almost-assured [...]

A deep learning approach for deriving winter wheat phenology from optical and SAR time series at field level

Felix Lobert, Johannes Löw, Marcel Schwieder, et al.

Subjects: Agricultural Science, Agriculture, Artificial Intelligence and Robotics, Environmental Monitoring

Information on crop phenology is essential when aiming to better understand the impacts of climate and climate change, management practices, and environmental conditions on agricultural production. Today’s novel optical and radar satellite data with increasing spatial and temporal resolution provide great opportunities to provide such information. However, so far, we largely lack methods that [...]

Information trust and groundwater management: Evaluating the role of formal versus informal information sources in adoption of groundwater conservation practices among California farmers

Published: 2023-06-21
Subjects: Agriculture

The future of farming in many water-stressed regions will depend in large part upon sustainable management of groundwater. Understanding the drivers associated with uptake of groundwater conservation practices in agriculture is thus critical for policy, programmatic, and technical support development. While a rich body of research has explored farmers’ conservation practice adoption, [...]
