Data mining by watching old documentary TV programs to learn about the relationships between people’s lives and the landscape in Sakha in the perestroika era at the end of the 1980s

Shin Nagai, Ayumi Kotani, Yasuyuki Maruya, et al.

Published: 2022-08-14
Subjects: Geography

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 [...]

Developing seagrass index for long term monitoring of Zostera japonica seagrass bed: a case study in Yellow River Delta, China

Qingqing Zhou, Yinghai Ke, Xinyan Wang, et al.

Subjects: Earth Sciences, Environmental Monitoring, Environmental Sciences, Geographic Information Sciences, Geography, Physical and Environmental Geography, Remote Sensing

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 [...]

A mid-20th century estimate of global vegetation carbon stocks based on inventory statistics

Manan Bhan, Patrick Meyfroidt, Sarah Matej, et al.

Subjects: Environmental Studies, Forest Sciences, Geography

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 [...]

Analyzing the uncertainty of the CORINE Land Cover time series (1990-2018) for Spain

David García-Álvarez, María Teresa Camacho Olmedo

Subjects: Environmental Studies, Geographic Information Sciences, Geography, Human Geography, Nature and Society Relations, Other Geography, Physical and Environmental Geography, Remote Sensing, Spatial Science

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 [...]

Structural uncertainty and uncertainty management in four common Land Use Cover Change (LUCC) model software packages. A comparison

Subjects: Environmental Studies, Geographic Information Sciences, Geography, Other Geography, Remote Sensing, Spatial Science

Research on the uncertainty of Land Use Cover Change (LUCC) models is still limited. Through this paper, we aim to globally characterize the structural uncertainty of four common software packages (CA_Markov, Dinamica EGO, Land Change Modeler, Metronamica) and analyse the options that they offer for uncertainty management. The models have been compared qualitatively, based on their structures [...]

Setting up a Land Use Cover Change model application for Greater Sydney. Lessons learnt and challenges ahead

Subjects: Environmental Studies, Geographic Information Sciences, Geography, Human Geography, Nature and Society Relations, Other Geography, Remote Sensing, Spatial Science

This chapter presents a Land Use Cover Change (LUCC) model application developed for Greater Sydney. It aims to help decision making in the context of the strategic and spatial planning of Greater Sydney. To this end, the model simulates the dynamics of industrial, low density residential and medium-high density residential areas at spatial resolution of 100x100 m. A series of three Land Use [...]

University of Sheffield Department of Geography Policy on Equality, Diversity and Inclusion for field classes

Ann Rowan, Eric Olund, Jenny Pickerill

Published: 2022-01-28
Subjects: Earth Sciences, Geography, Higher Education, Scholarship of Teaching and Learning

Field-based teaching forms an important part of BSc/BA degree courses in Human Geography, Physical Geography, Environmental Science and taught postgraduate courses. The aim of this policy is to ensure that all students and teaching staff are able, and feel safe, to participate fully in compulsory and optional field classes offered by the Department of Geography. This is shared with the intention [...]

Optimizing nature-based solutions by combining social equity, hydro-environmental performance, and economic costs through a novel Gini coefficient

A robust multi-functional framework for widespread planning of nature-based solutions (NBS) must incorporate components of social equity and hydro-environmental performance in a cost-effective manner. NBS systems address stormwater mitigation by increasing on-site infiltration and evaporation through enhanced greenspace while also improving various components of societal well-being, such as [...]

Tidal marsh resilience to sea level rise controlled by vertical accretion and landward migration under nature-based human adaptation scenarios

Xiaoguang Ouyang, Rod Connolly, Shing Yip Lee

Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Studies, Geography, Life Sciences, Marine Biology, Plant Sciences

Tidal marshes are not only lost to human disturbance but also face the threat of sea level rise (SLR). However, current earth system models used to estimate future changes in wetland extent omit wetland’s real responses to SLR without field observations. We synthesised global data on sediment accretion rate (SAR) and surface elevation change (SEC) for tidal marshes and developed a mathematical [...]

Ensuring taught fieldwork is a positive, generative, collective, and valuable experience for all participants requires considerations beyond course content. To guarantee safety and belonging, participants’ identities (backgrounds and protected characteristics) must be considered as a part of fieldwork planning and implementation. Furthermore, getting fieldwork right is an important step in [...]

Story-based futures serve an important role in climate change scenario development. Stories are particularly useful in exploring sea level rise possibilities, since we know many coastal areas are specifically vulnerable to accelerating rises in sea level. This discrete change in coastline is different from most other climate change impacts, and offers a clear basis for scientifically-informed, [...]

The disaster trap: cyclones, tourism, colonial legacies, and the systemic feedbacks exacerbating disaster risk

Eli Lazarus

Published: 2021-05-04
Subjects: Geography, Human Geography, Nature and Society Relations, Physical and Environmental Geography

The long, open-ended period of recovery from a disaster event is the phase of a disaster that the interdisciplinary field of disaster studies struggles to understand. In the process of rebuilding, places do not simply reset – they transform, often in ways that confound any reduction of disaster risk, instead making people and settings more vulnerable to future hazard events. Reducing disaster [...]
