Handbook on Urban Sustainability
No full textA PARAMOUNT CONCEPT The following article, authored by Mathis Wackernagel et al, illustrates the Ecological Footprint concept developed by William Rees and Mathis Wackernagel (1996). This is a fundamental concept to measure sustainability and the unequal use of land resources on the planet. The Ecological Footprint is mentioned many times in this book in different chapters, showing its importance. For this reason it is believed that the inclusion of this paper as a preface to this handbook will not only enhance the reader’s understanding of the concept but will also aid in understanding further chapters. Nolberto Munier Editor THE ECOLOGICAL FOOTPRINT OF CITIES AND REGIONS: COMPARING RESOURCE* AVAILABILITY WITH RESOURCE DEMAND By Mathis Wackernagel, Justin Kitzes, Dan Moran, Steven Goldfinger and Mary Thomas SUMMARY: Cities and regions depend on resources and ecological services from distant ecosystems. The well-being of city and region residents is affected by both the health and availability of these ecosystems, especially in today’s ecologically strained world.* Reprinted by permission of Sage Publications Ltd. from: Wackernagel, Mathis et al,“The ecological footprint of cities and regions: comparing resource availability with resource demand”, Environment and Urbanization, Vol. 18, No. 1, in press.(© Sage Publications Ltd., 2006). 1© Sage Publications, 2006 2 Preface The management of a city or region’s resource metabolism, including the natural capital that supports these flows, is becoming increasingly a central concern to cities and regions that want to succeed
Pretrained Transformers of "B-spline Curve Approximation With Transformer Neural Networks" article
No full textPretrained Transformers of B-spline Curve Approximation With Transformer Neural Networks article
This dataset contains model checkpoints along with configuration and log files of trained transformer neural networks. Those networks have been trained following the methodology described in the link article. The following github repository can be used to read, test and process the data found in this dataset : bspline-curve-approximation-transformer.
The Readme file can help you understand the nature of the data to help you in treating it yourself. A recent version of Pytorch is required to load some of the data (i.e. model checkpoints and parameters).
The training logs and inference results come as csv and txt files and can be read and processed by any software of your choice.
See Readme.md for a more detailed description of files and parameters. Feel free to contact the author regarding questions/problems with the data.</p
Global and local estimates of environmental flow requirements to sustain river ecosystems are poorly correlated
No full textData repository for ‘Global and local estimates of environmental flow requirements to sustain river ecosystems are poorly correlated ‘
prepared by Mathis L. Messager ([email protected])
1. Overview and background ----------------------------------------------------------
This documentation describes the input and output data associated with the analysis presented in: Messager, M. L., Dickens, W. S. C., Eriyagama, N., Tharme, R. E., Stassen, R. (2024). Limited comparability of global and local estimates of
environmental flow requirements to sustain river ecosystems. https://doi.org/10.1088/1748-9326/ad1cb5.
Environmental flows (e-flows) are a central element of sustainable water resource management to mitigate the detrimental impacts of hydrological alteration on freshwater ecosystems and their benefits to people. Many nations strive to protect e-flows through policy, and thousands of local-scale e-flows assessments have been conducted globally, leveraging data and knowledge to quantify how much water must be provided to river ecosystems, and when, to keep them healthy. However, e-flows assessments and implementation are geographically uneven and cover a small fraction of rivers worldwide. This hinders globally consistent target-setting, monitoring and evaluation for international agreements to curb water scarcity and biodiversity loss. Therefore, dozens of models have been developed over the past two decades to estimate the e-flows requirements of rivers seamlessly across basins and administrative boundaries at a global scale.There has been little effort, however, to benchmark these models against locally derived e-flows estimates, which may limit confidence in the relevance of global estimates. The aim of this study was to assess whether current global methods reflect e-flows estimates used on the ground, by comparing global and local estimates for 1194 sites across 25 countries. We found that while global approaches broadly approximate the bulk volume of water that should be precautionarily provided to sustain aquatic ecosystems at the scale of large basins or countries, they explain a remarkably negligible 0%–1% of the global variability in locally derived estimates of the percentage of river flow that must be protected at a given site. Even when comparing assessments for individual countries, thus controlling for differences in local assessment methods among jurisdictions, global e-flows estimates only marginally compared (R2 ⩽ 0.31) to local estimates. Such a disconnect between global and local assessments of e-flows requirements limits the credibility of global estimates and associated targets for water use. To accelerate the global implementation of e-flows requires further concerted effort to compile and draw from the thousands of existing local e-flows assessments worldwide for developing a new generation of global models and bridging the gap from local to global scales..
The data repository includes data required to perform this analysis as well as the data outputs from this analysis. Input data from local e-flow assessments included herein were either provided by collaborators or extracted from published governmental and academic reports by the authors. Input hydrographic data not available for download elsewhere were provided by Dr. Bernhard Lehner and hydrological simulations from PCR-GLOBWB 2.0 at a spatial resolution of 5 arc-min (not provided herein) were provided by Dr. ir. Edwin H. Sutanudjaja.
All scripts necessary to reproduce this analysis are freely available for all purposes (and can be copied, modified and distributed) at: https://github.com/messamat/globalEF_testPy (for data-preformatting and global e-flow calculations) and https://github.com/messamat/globalEF_testR (for comparing global and local MAF and e-flow estimates). The structure of the analysis relies as much as possible on good enough practices in scientific computing, which users are encouraged to read.

Wir müssen daher bewusst den Kurs ändern und neu gestalten.“
