Indramayu is a district in West Java that is known for being the leading producer of rice and brackish salt. The production of these two commodities is strongly influenced by hydroclimatological conditions, making accurate and reliable long-term estimates crucial. In this study, we evaluated a simple feed-forward deep neural network (DNN) model that could potentially be used as a candidate for [...]
Standardized Benchmark of Historical Compound Wind and Solar Energy Droughts Across the Continental United States
Published: 2023-06-23
Subjects: Meteorology, Oil, Gas, and Energy, Statistical Methodology, Sustainability
As we move towards a decarbonized grid, reliance on weather-dependent energy increases as does exposure to prolonged natural resource shortages known as energy droughts. Compound energy droughts occur when two or more predominant renewable energy sources simultaneously are in drought conditions. In this study we present a methodology and dataset for examining compound wind and solar energy [...]
Improving the relevance of the Shared Socioeconomic Pathways for sustainability science
Published: 2023-06-21
Subjects: Sustainability
Sustainability science is a discipline which is strongly concerned with exploring the achievement of sustainable futures. One way in which this is done is through scenarios. The Shared Socioeconomic Pathways (SSPs), developed for climate science, have been widely adopted by modellers to analyse sustainable futures. We question whether the SSPs are fit-for-purpose for examining sustainable [...]
A paradigm shift towards decentralized cloud-integrated spatial data infrastructures: Lessons learned and solutions provided for public authorities
Published: 2023-06-08
Subjects: Agriculture, Computer and Systems Architecture, Numerical Analysis and Scientific Computing, Sustainability
Digital transformation is a key to turn public authorities into organisations that make decisions based on data-driven insights. The use of big geodata can enable public authorities to tackle complex sustainability issues. However, the efficient management of large amounts of geodata through implementing viable data infrastructures represents a major challenge for public authorities. In this [...]
The Future in Anthropocene Science
Published: 2023-05-23
Subjects: Climate, Environmental Studies, Nature and Society Relations, Sustainability
The Anthropocene is the present time of human-caused accelerating global change, and new forms of Anthropocene risk are emerging that society has hitherto never experienced. Science and policy are grappling with the temporal and spatial magnitude of these changes, as well as the diminishing margin between science and policy itself. However, there is a gap in the transparency — and perhaps even in [...]
Spatiotemporal inconsistencies in Landsat satellite observations bias environmental-change analyses and monitoring
Published: 2023-05-19
Subjects: Environmental Monitoring, Geographic Information Sciences, Physical and Environmental Geography, Remote Sensing, Sustainability
Satellite remote sensing is vital for research, monitoring, and policy addressing environmental-change and sustainability issues from climate and ecosystem changes to food and water security. Here, Landsat satellite data play a crucial role, thanks to their unique global, long-term, and high-resolution coverage. Yet, spatial and temporal data gaps in the Landsat archive may propagate into derived [...]
Ecological Flows in Southern Europe: status and trends in non-perennial rivers
Published: 2023-05-16
Subjects: Biodiversity, Environmental Engineering, Environmental Studies, Other Ecology and Evolutionary Biology, Sustainability, Water Resource Management
The concept of environmental flows (E-Flows) describes the streamflow that is necessary to maintain river ecosystems. Although a large number of methods have been developed, a delay was recorded in implementing E–Flows in non-perennial rivers. The general aim of the paper was to analyse the criticalities and the current state of implementation of the E-Flows in non-perennial rivers of southern [...]
Assessing the potential of low transmissivity aquifers for ATES systems: a case study in Flanders (Belgium)
Published: 2023-04-21
Subjects: Geology, Sustainability, Water Resource Management
The Member States of the European Union pledged to reduce greenhouse gas emissions by 80-95% by 2050. Shallow geothermal systems might substantially contribute by providing heating and cooling in a sustainable way through seasonally storing heat and cold in the shallow ground (<200m). When the minimum yield to install a cost-effective aquifer thermal energy storage (ATES) system cannot be met, [...]
Matrix-based Methods for Regionalized Life Cycle Assessment
Published: 2023-04-14
Subjects: Sustainability
We develop a comprehensive computational framework for matrix-based regionalized life cycle assessment (LCA). When life cycle inventories and impact assessment methods have different spatial scales, spatial allocation is needed to map inventory locations to impact assessment spatial units. We review spatial allocation based on intersected areas and existing background emissions, and propose using [...]
Revisiting the Climate Narrative

Subjects: Agriculture, Climate, Ecology and Evolutionary Biology, Environmental Engineering, Environmental Studies, Food Science, Forest Management, Hydrology, Natural Resources and Conservation, Natural Resources Management and Policy, Oil, Gas, and Energy, Other Environmental Sciences, Soil Science, Sustainability, Water Resource Management
The rise in atmospheric carbon dioxide is chiefly tied to land stewardship. Farmers and loggers have removed the plants that, until the industrial era, kept the soil fungi alive, kept soil emissions nearby by breaking the wind, and soaked those up. The result is plumes of carbon dioxide. Putting plants back in would curb these emissions. Farmers and loggers could address biodiversity loss [...]
Ambitious food system interventions required to mitigate the risk of exceeding Earth’s environmental limits

Transforming the global food system is necessary to avoid exceeding the Earth’s environmental limits. A robust evidence base is crucial to assess the scale and combination of interventions required for a sustainable transformation. We developed a risk assessment framework, underpinned by an evidence synthesis of global food system modeling studies, to quantify the potential of individual and [...]
Data, knowledge and modeling challenges for science-informed management of river deltas
Published: 2023-03-17
Subjects: Environmental Engineering, Environmental Sciences, Natural Resources and Conservation, Natural Resources Management and Policy, Other Civil and Environmental Engineering, Other Environmental Sciences, Sustainability, Water Resource Management
450 million people live on river deltas and thus on land that is precariously low above the sea level and sinking because of human activities and natural processes. Although global debates around coastal risk typically focus on sea level rise, it is sinking lands and rising seas that together endanger lives and livelihoods in river deltas. However, the ability to quantify and address those risks [...]

Rapid seaward expansion of seaport footprints worldwide
Published: 2023-02-25
Subjects: Civil Engineering, Geographic Information Sciences, Geomorphology, Other Environmental Sciences, Physical and Environmental Geography, Remote Sensing, Sustainability
As global maritime traffic increases, seaports grow to accommodate and compete for higher volumes of trade throughput. However, growth trajectories of seaport footprints around the world have gone unmeasured, likely because of a lack of readily available spatio-temporal data. Here, we use geospatial analysis of global satellite imagery from 1990–2020 to show that 65 seaports among the world's top [...]
Considerable gaps in our global knowledge of potential groundwater accessibility
Published: 2023-02-12
Subjects: Geology, Hydrology, Sustainability, Water Resource Management
At what depth groundwater can be found below the land surface is key to understanding whether it is potentially accessible to ecosystems and humans, or what role it plays in the water cycle. Knowledge of ground-water table depth (WTD) exists at regional scales in many places, but a bottom-up knowledge aggregation to obtain a coherent global picture is exceptionally challenging. Uncertainty in [...]
