The research scope of this paper is to apply spatial object based image analysis (OBIA) method for processing panchromatic multispectral image covering study area of Brussels for urban mapping. The aim is to map different land cover types and more specifically, built-up areas from the very high resolution (VHR) satellite image using OBIA approach. A case study covers urban landscapes in the [...]
Report for the Yujiang Government on the China-UK Knowledge Exchange Project for the Red Soil Critical Zone
Published: 2018-12-19
Subjects: Environmental Sciences, Environmental Studies, Geography, Natural Resources Management and Policy, Nature and Society Relations, Physical Sciences and Mathematics, Social and Behavioral Sciences
Knowledge exchange (KE) has been increasingly used to translate the scientific findings to produce outputs that inform land users and policy makers to lead to the sustainable environmental management. As part of the wider China-UK Critical Zone (CZ) programme, a KE research project was conducted to help ensure research results can be more effectively delivered to those who need them. Following on [...]
Report for the Puding Government on the China-UK Karst Knowledge Exchange Project

Subjects: Environmental Sciences, Environmental Studies, Geography, Nature and Society Relations, Physical and Environmental Geography, Physical Sciences and Mathematics, Social and Behavioral Sciences, Water Resource Management
The report summaries the first stage output from the Knowledge Exchange (KE) research carried out in one of China’s rural areas in the karst landscape, aiming to understand the local knowledge sharing dynamic and learning preference of stakeholders. A social science survey was carried out in November 2016 in 7 villages of Puding County to 15 county leaders, 8 town leaders and 24 village leaders [...]
Summary Report of China-UK Knowledge Exchange Project for Their Critical Zone Programme
Published: 2018-12-12
Subjects: Environmental Sciences, Environmental Studies, Geography, Nature and Society Relations, Physical and Environmental Geography, Physical Sciences and Mathematics, Social and Behavioral Sciences, Water Resource Management
Global to local environmental policy-making is increasingly evidenced-based. Knowledge exchange (KE) is increasingly used by environmental scientists and policymakers, to deliver evidence-based policy and practice. This study presents the output from the KE research project within the China-UK Critical Zone (CZ) programme in China from 2016 to 2018, focussing on understanding: (i) the key issues [...]
Creating a Model to Optimize and Evaluate the Heat-Reducing Capacity of Green Infrastructure
Published: 2018-09-11
Subjects: Civil and Environmental Engineering, Engineering, Environmental Engineering, Environmental Public Health, Environmental Studies, Medicine and Health Sciences, Public Health, Social and Behavioral Sciences
As global warming increases temperatures worldwide, cities are experiencing even greater temperatures due to the urban heat island effect, which is the trapping of heat in “gray” urban infrastructure. Cities are combatting this with green infrastructure (GI) initiatives, such as the Department of Environmental Protection (DEP) GI initiative in New York City. However, these programs are often [...]
Powers of 10: cross-scale optimization of social agencies for rapid climate and sustainability action
Published: 2018-08-27
Subjects: Education, Environmental Sciences, Environmental Studies, Geography, International and Area Studies, Library and Information Science, Life Sciences, Medicine and Health Sciences, Physical Sciences and Mathematics, Social and Behavioral Sciences, Sustainability
Achieving the goals of the Paris Agreement and related sustainability initiatives will require halving of greenhouse gas emissions each decade from now on through to 2050, when net zero emissions should be achieved. To reach such significant reductions requires a rapid and strategic scaling of existing and emerging technologies and practices, coupled with economic and social transformation and [...]

Knowledge in the Dark: Scientific Challenges and Ways Forward

Subjects: Earth Sciences, Education, Environmental Sciences, Environmental Studies, Higher Education, Language and Literacy Education, Liberal Studies, Library and Information Science, Life Sciences, Medicine and Health Sciences, Physical Sciences and Mathematics, Public Health, Science and Mathematics Education, Social and Behavioral Sciences
We propose the concept of knowledge in the dark – or short: dark knowledge – and outline how it can help clarify why in our current era of Big Data, the knowledge (i.e. evidence-based understanding) of people does not seem to be substantially increasing despite a rapid increase in produced data and information. Key reasons underlying dark knowledge are: (1) the production of biased, erroneous or [...]
Communicating Unnatural Disasters
Published: 2018-01-03
Subjects: Earth Sciences, Engineering, Environmental Studies, Physical Sciences and Mathematics, Risk Analysis, Social and Behavioral Sciences
Off the back of the 2017 hurricanes we extend the notion of human-influenced meteo-hydro hazards to include deeper geophysical events. We question where to place Human responsibility in a changing world, and we outline ways to bridge the gaps between scientist’s technical knowledge and ‘meaning’ as it is understood by people at risk. This short Op-ed has been rejected by Science after two rounds [...]
The crisis of a paradigm. A methodological interpretation of Tohoku and Fukushima catastrophe
Published: 2017-12-05
Subjects: Earth Sciences, Environmental Studies, Geophysics and Seismology, Physical Sciences and Mathematics, Social and Behavioral Sciences, Tectonics and Structure
The 2011 Japanese disaster often presented as a ‘new Chernobyl’ accumulated the effects of earthquake, tsunami and of the subsequent nuclear accident at Fukushima. In the light of this disaster, we review methodological rea- sons both from geophysical and philosophical perspectives that lead the scientific and technological communities to flawed conclusions, prime cause of the disaster. The [...]
Ratcheting up ambition in climate policy
Published: 2017-11-11
Subjects: Climate, Environmental Studies, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics, Social and Behavioral Sciences
The historic Paris Agreement aims to constrain the peak increase in global mean temperature to 1.5 °C, or at least well below 2 °C. Every country has committed to device their own “nationally determined contributions” towards this target. These contributions are only proscribed for the coming 10-15 years with a regular reassessment of them against the global target. Here we use a global [...]
Pastoralism may have delayed the end of the green Sahara
Published: 2017-11-06
Subjects: Earth Sciences, Environmental Studies, Geology, Physical Sciences and Mathematics, Social and Behavioral Sciences
The benefits of pastoralism for marginal, arid environments are often not appreciated. One notable past example of the human response to encroaching desertification comes from the regional climate deterioration after the most recent African Humid Period, which ended around 5,500 years ago. Recent evidence points to a population expansion in northern Africa prior to this, associated with the [...]
