The mountainous part of northern Thailand is subject to an intense haze episode occurring almost every year between January and May. In the last couple of decades, this atmospheric phenomenon has been extensively covered in the media and is now a main concern for the population living in this area. In this review, we synthesized the information available from hundreds of publications on air [...]
Energy Use and Greenhouse Gas Emissions in Selected Tea Factories in Kenya
Published: 2023-11-30
Subjects: Environmental Studies
Tea sector is a major contributor to Kenya’s economy through foreign exchange via export. However, extensive amount of energy is required to produce one kilogram of tea, making tea processing energy-intensive. Comparing greenhouse gas emissions from different types of energy consumed in tea factories is imperative to enable policymakers make informed intervention in emission reduction. Reducing [...]
Unintended consequences of nature-based solutions: Social equity and flood buyouts
Published: 2023-11-25
Subjects: Environmental Studies
Nature-based solutions (NbS) can serve as effective strategies to promote the resilience of both people and ecosystems in the face of climate change. However, these solutions can exacerbate existing social inequities if they fail to adequately consider the complex social contexts in which they are implemented. To better understand the equity implications of NbS, and how to design and deliver such [...]
Wildfires increasingly threaten oil and gas wells in the western United States with disproportionate impacts on marginalized populations
Published: 2023-11-15
Subjects: Environmental Health and Protection, Environmental Sciences, Environmental Studies, Oil, Gas, and Energy
The western United States is home to most of the nation’s oil and gas production and, increasingly, wildfires. We examined historical threats of wildfires for oil and gas wells, the extent to which wildfires are projected to threaten wells as climate change progresses, and exposure of human populations to these wells. From 1984–2019, we found that cumulatively 102,882 wells were [...]
Defining Plastic Pollution Hotspots
Published: 2023-11-10
Subjects: Environmental Sciences, Environmental Studies, Fresh Water Studies, Hydrology
Plastic pollution in the natural environment poses a growing threat to ecosystems and human health, prompting urgent needs for monitoring, prevention and clean-up measures, and new policies. To effectively prioritize resource allocation and mitigation strategies, it is key to identify and define plastic hotspots. UNEP’s draft global agreement on plastic pollution mandates prioritizing hotspots, [...]
Fantastic Wetlands and Why to Monitor Them: Demonstrating the Social and Financial Benefit Potential of Methane Abatement through Salt Marsh Restoration
Published: 2023-10-27
Subjects: Environmental Studies
Salt marsh restoration has the potential to reduce greenhouse gas emissions thereby providing an opportunity for blue carbon crediting, but implementation has been limited to date because of insufficient data and validation. Freshening salt marshes are sources of methane emissions, which present an opportunity for states to address this source of potent greenhouse gas emissions if restored to [...]

Modern-day data sets in geosciences may comprise hundreds or thousands of geolocated time series. Despite all the automated tools and new algorithms now available to process and prepare those data before using them in research projects, it can be useful or even necessary to visualise and investigate them manually. Whether it be for data quality assessment, for the preparation of a training data [...]
Mapping the Landscape of Water and Society Research: Promising Combinations of Compatible and Complementary Disciplines
Published: 2023-10-13
Subjects: Environmental Education, Environmental Engineering, Environmental Studies, Geographic Information Sciences, Human Geography, Hydraulic Engineering, Hydrology, Natural Resource Economics, Natural Resources Management and Policy, Physical and Environmental Geography, Spatial Science, Sustainability, Water Resource Management
Coupled human-water systems (CHWS) are diverse and have been studied across a wide variety of disciplines. Integrating multiple disciplinary perspectives on CHWS provides a comprehensive and actionable understanding of these complex systems. While interdisciplinary integration has often remained elusive, specific combinations of disciplines might be comparably easier to integrate (compatible) [...]

Tabor Park for the benefit of individuals, organizations and the Park Bureau; to identify and help solve problems; and to participate in park planning projects.”(FMTP) During the winter of 2021 with covid closures of the Visitor Center, Tree Medicine hikes were [...]
Field Report No. 1 - Tabor Tree Project Report 2021
Published: 2023-10-10
Subjects: Earth Sciences, Ecology and Evolutionary Biology, Environmental Sciences, Environmental Studies, Nature and Society Relations, Other Plant Sciences
In this Survey, the Tabor Tree Project identified 130 trees randomly in all 12 zones of the park called Mt. Tabor in Portland, Oregon. The Majority of the Trees at Mt. Tabor Park are conifers, and specifically Douglas Fir who can live longer than 1,000 years. The oldest one in the park is 496 years old, and sprouted sometime around 1520 AD. Through the efforts of Tree Medicine hikes and Citizen [...]
Stay or go? Geographic variation in risks due to climate change for fishing fleets that adapt in-place or adapt on-the-move
Published: 2023-08-17
Subjects: Environmental Studies
From fishers to farmers, people across the planet who rely directly upon natural resources for their livelihoods and well-being face extensive impacts from climate change. However, local- and regional-scale impacts and associated risks can vary geographically, and the implications for development of adaptation pathways that will be most effective for specific communities are underexplored. To [...]
Gender relations and decision-making on climate change adaptation in rural East African households: A qualitative systematic review
Published: 2023-08-09
Subjects: Environmental Studies
Background: Climatic changes are threatening rural livelihoods in East Africa. Evidence suggests that climate change adaptation in this context might reproduce inequitable intra-household gender relations and that adaptation may be more effective when women are involved in meaningful ways. Hence, a nuanced understanding of the gendered nature of intra-household adaptation decision-making is [...]
Urban demand for cooking fuels in two major African cities and implications for policy
