The separation between nature and society, of concern within social science and interdisciplinary discussions, has generated a division that often characterizes the way communities perceive their environment. The arts have played an important role in demonstrating the entanglement of Earth and society through their ability to frame and shape the dynamics of the Earth across sensations. This has [...]

Large-scale wind and solar photovoltaic (PV) infrastructures are expanding rapidly in Brazil. These projects can exacerbate struggles for land rooted in weak land governance, with negative impacts for traditional populations due to loss of access to common lands. Here, we trace how green grabbing, i.e. the large-scale appropriation and control of (undesignated) public lands, both formally legal [...]

Transportation systems can be significantly affected by flooding, leading to physical damage and subsequent adverse impacts such as increased travel distance to essential services. Even though flooding is a frequently recurring phenomenon that can affect thousands of people per event, there are limited accessible online tools available for analyzing and visualizing flood risk for supporting [...]

The Nasia river serves as the primary source of domestic water supply for over 5000 households in the Nasia catchment. However, the river is currently experiencing water stress conditions, causing an imbalance between the demand for water and the available supply. In this study, we evaluated the impact of climate and environmental factors on changes in domestic water supply in the Nasia [...]

This paper examines the performance of ChatGPT, a large language model (LLM), in a geographic information systems (GIS) exam. As LLMs like ChatGPT become increasingly prevalent in various domains, including education, it is important to understand their capabilities and limitations in specialized subject areas such as GIS. Human learning of spatial concepts significantly differs from LLM training [...]

This paper explores the concept of leveraging generative AI as a mapping assistant for enhancing the efficiency of collaborative mapping. We present results of an experiment that combines multiple sources of volunteered geographic information (VGI) and large language models (LLMs). Three analysts described the content of crowdsourced Mapillary street-level photographs taken along roads in a small [...]

The study analyzed the daily extreme rainfall indices and its consequences on Meher (summer) season cereal crop calendar in the agro-climatic zones (ACZs) of a watershed. Long-term (1981-2019) rainfall data for 50 sample grid points with a spatial resolution of 5 5 km from Climate Hazards Group Infrared Precipitation (CHIRPS) was considered. Focus group discussions were employed to identifying [...]

In the following pages, we give a short introduction to a new integrated global assessment model: The Earth4All model of human wellbeing on a finite planet towards the year 2100. The Earth4All (E4A) model has evolved over a fifteen-year period and represents a summary of insights we have gained during all these years (See Appendix 1 for a list of the main publications that form the foundation for [...]

Majapahit was the largest Hindu-Buddhist empire that ruled the Indonesian archipelago from the late 13th to mid-16th centuries CE. Only now there is still a lot of history surrounding the Majapahit era that has yet to be revealed. One is about how environmental factors influenced the political dynamics at that time. This study tries to discuss the influence of hydroclimate regimes using the Paleo [...]

Real-world environmental problems are typically vast, urgent, and complex. Confronted with such problems, we are often tempted to act fast by pulling together little bits and pieces from different fields and simply adding these to pre-existing models and frameworks. Seldom, though, do we pause long enough to look whether and for how long those larger structures we build can support reliable [...]

To accurately evaluate the spatiotemporal variability of ecosystem functions and services, as well as biodiversity, under a rapidly changing climate and shifting anthropogenic activities, it is an important but challenging task to retrieve information about past relationships among society, people’s lives, and the landscape. We watched documentary TV programs broadcast by the Japanese public [...]

Seagrass beds offer unique and vital ecological services as an important blue carbon ecosystem in coastal wetlands. Zostera japonica is an intertidal seagrass species native to eastern Asia and is one of the most widely distributed seagrass species in China. However, little is known on the long-term variations of Z. japonica extents. Automatic mapping method for Z. japonica seagrass beds is in [...]

Biomass carbon stocks (BCS) play a vital role in the climate system, but benchmarked estimates prior to the late 20th century remain scarce. Here, by making use of an early global forest resource assessment and harmonizing information on land use and carbon densities, we establish a global BCS account for the year 1950. Our best-guess BCS estimate is 450.7 PgC (median of all modulations: 518.3 [...]

Rural-urban classifications are essential for analyzing geographic, demographic, environmental, and social processes across the rural-urban continuum. Most existing classifications are, however, only available at relatively aggregated spatial scales, such as at the county scale in the United States. The absence of rurality or urbanness measures at high spatial resolution poses significant [...]

CORINE Land Cover is one of the most relevant Land Use Cover (LUC) databases in Europe because of its degree of detail and long time series. Although some studies have assessed the uncertainty of the database for specific years and periods, no work has been found that analyses all the available CORINE time series (1990-2018). In this study, we analyze the uncertainties of the CORINE time series [...]
