Mapping the Topographic Fingerprints of Humanity Across Earth – EOS

By , Giulia Sofia, and Erle Ellis

If increasingly globalized societies are to make better land management decisions, the geosciences must globally evaluate how humans are reshaping Earth’s surface

Since geologic time began, Earth’s surface has been evolving through natural processes of tectonic uplift, volcanism, erosion, and the movement of sediment. Now a new force of global change is altering Earth’s surface and morphology in unprecedented ways: humanity.

Human activities are leaving their fingerprints across Earth (Figure 1), driven by increasing populations, technological capacities, and societal demands [e.g., Ellis, 2015; Brown et al., 2017; Waters et al., 2016]. We have altered flood patterns, created barriers to runoff and erosion, funneled sedimentation into specific areas, flattened mountains, piled hills, dredged land from the sea, and even triggered seismic activity [Tarolli and Sofia, 2016]. These and other changes can pose broad threats to the sustainability of human societies and environments.

If increasingly globalized societies are to make better land management decisions, the geosciences must globally evaluate how humans are reshaping Earth’s surface. A comprehensive mapping of human topographic signatures on a planet-wide scale is required if we are to understand, model, and forecast the geological hazards of the future.

Understanding and addressing the causes and consequences of anthropogenic landform modifications are a worldwide challenge. But this challenge also poses an opportunity to better manage environmental resources and protect environmental values [DeFries et al., 2012].

They’re here….our print Hydrological Sciences Journals 2015 are here!

So I am doing another happy dance as Volume 60 Issues 1-8 of our Hydrological Sciences Journal have been delivered. We are expected to get four more issues, i.e. 9-12.

So Taylor and Francis have definitely made my day and I hope yours too since this information is now available for perusal.

Please see below for a breakdown of what each of the four books contain.

  1. Hydrological Sciences Journal Volume 60 Issues 1-2 2015:

This journal contains 379 pages and presents articles on topics such as climate change risks and water management; future water stress; modelling regional impacts and water resources; peak discharge estimation; surface soil water content; hydrological trends; salt intrusion model in Malaysia; water yield effects; land surface temperature; index-flood model; sediment transfer; artificial recharge by floodwater and transient phreatic surface mound.

Also contained in this journal is a book review for Introduction to Physical Hydrology by Martin R. Hendriks, 2010; Oxford University Press

2. Hydrological Sciences Journal Volume 60 Issues 3-4 2015:

This journal presents articles and case studies on a wide variety of topics which include bias compensation in flood frequency; hydrograph evaluation; catchment behaviour, rainfall selection and flash flood; data series interpolation; runoff of climate change; runoff and water temperature; global hdrological models; current trends in climate parameters; curve number adjustment; modelling climate and land-use; sewer overflow; groundwater depletion; water balance; source identification and water storage.

Air Quality Management – Wiley

I remember when I had done a natural sciences course, how dire the outlook, in terms of, water resources and the environmental sustainability looked. I am sure that if many of my classmates hadn’t thought about the environment and its relation to their survival and that of the next generation, it definitely would have been thought of then and afterwards.

At the Wiley Online Library I came across a text entitled “Air Quality Management” (March, 2014), which is one of four texts to assist readers in developing Environmental Impact Assessments (EIAs).

This document offers one an introduction to the atmosphere around us and the units of concentration. It also discusses the importance of meteorology and the part it plays in air quality, before detailing the main types of air pollutants, their sources, and their effects on humans and their environments. Further chapters discuss measurement technologies and systems, as well as a selection of control and elimination methods. The book also details methods of modelling atmospheric dispersion.
