In this journal article, the authors – among them Darla Nickel and Melissa Keeley, both Ecologic Institute alumnae – analyze the stormwater infrastructure of the two cities. The focus lies on the question of how green and grey infrastructure can most successfully be combined and integrated for rain-water management. While grey infrastructure refers to conventional piped drainage and water treatment systems, the term "green infrastructure" encompasses land and plant based ecological treatment systems and processes. The report can be purchased on the homepage of the publisher "Springer-Verlag".

The precautionary principle is used in arguments both for and against climate engineering: On the one hand, the principle can suggest caution against climate engineering so as to minimize the (unknown) risks of proposed techniques to the environment and health. On the other hand, arguments can be made that climate engineering is a precautionary measure against the (known) risks of climate change. This article, written by Elizabeth Tedsen and Gesa Homann, provides an overview of this debate and what the precautionary principle means in a climate engineering context.

This survey of Dominik Müller, Senior Analyst at Ecologic Institute, describes the regulatory and policy framework for the promotion of renewable energies in Germany as amended by the "Energiewende" announced by the German Federal Government in the wake of the Fukushima nuclear power plant disaster. The article focuses on changes in the electricity sector chiefly through fundamental amendments of the Renewable Energies Sources Act ("Erneuerbare-Energien-Gesetz – EEG") since 2011. Moreover, the article also discusses the political and regulatory situation for the use of renewable energies in the heat and transport sectors in Germany.

The study examined the charges levied on patients for the diagnosis and treatment of the ten most common outpatient conditions handled in the emergency department (ED). The results of research undertaken by scientists and faculty at the University of California, San Francisco, Stanford University, the University of Minnesota, and Ecologic Institute have been published in the scientific journal PLoS One. Based on a cross-sectional study of the 2006–2008 Medical Expenditure Panel Survey, the analysis was limited to outpatient visits with non-elderly, adult (years 18–64) patients with a single discharge diagnosis. A sample of 8,303 ED encounters was analyzed, which is representative of a total of 76.6 million ED visits during the studied 3-year period. It was found that charges varied significantly by diagnosis and across EDs for the same diagnosis. The study is available for download.

Which lessons for future projects can be learned from earlier stormwater management schemes in Germany? The authors of the report "German Experience in Managing Stormwater with Green Infrastructure" – among them Ecologic Institute's alumnae Darla Nickel, Wenke Schoenfelder and Melissa Keeley – specifically address this question. Based on two case studies, the authors examine policies, strategies and instruments integrating grey and green infrastructure. The article can be downloaded on the publisher's website.

Although Mongolia's GDP has grown consistently in recent years due to the booming mining sector, poverty is still widespread. This article aims to determine the extent to which agriculture contributes to food security in Mongolia and highlights the problems and challenges this sector is facing. In this article, published in the Geographische Rundschau, the authors Zoritza Kiresiewa (Ecologic Institute), Ankhtuya Altangadas, and Jörg Janzen answer these questions.

Mainstream economic indicators still dominate practical policy making. In this journal article, Lucas Porsch explains how the connection of sustainability measures and these mainstream indicators can be a tool for policy makers to understand and manage trade-offs between different sustainability categories.

The results of a research project undertaken by the Center for Earth Science Information Network (CIESIN) at Columbia University to which Ecologic Institute Senior Fellow Tanja Srebotnjak contributed have been published in the scientific journal Environmental Research Letters. The study produced geospatially explicit estimates of human net migration across ecosystems between 1970 and 2010.

The "Westphalian system" of international relations, based on delineation, non-interference, and separation, hinders effective management of environmental resources, such as trans-boundary rivers. In this article, R. Andreas Kraemer of Ecologic Institute explains how cooperation and sharing responsibilities over watercourses between states provided the basis for the US Constitution and the institutional order of the EU, and now drive a new transnationalism that erodes the Westphalian system. The article is available for download.

After the Fukushima incident, Germany was unique in being able to pass a law aiming to close all nuclear power plants by the end of 2022. Investments in the development, demonstration, and deployment of renewable energies over the past decades, along with the "feed-in tariff," which since 1991 has rewarded successful operators of renewable power plants, enabled Germany to do so.

In this article published in Conservation Letters, members of the interdisciplinary Research Group on Ecosystem Services examine the possibilities and perspectives for a reorientation of the EU's Common Agricultural Policy (CAP). The authors find that the current reform proposals do not take into account the knowledge generated by ecosystem research. They argue that the CAP should be reformed such that it serves as an instrument to safeguard ecosystem services from agricultural land.

The economic valuation of biodiversity and ecosystem services has become a widespread tool to inform policy-makers about the consequences of environmental change. Assessments of environmental impacts at large geographic scales have led to growing policy and academic interest in transferring ecosystem service values from existing valuation studies to other ecosystem sites at a large geographic scale. This paper, published in Environmental and Resource Economics, proposes a methodology for scaling up ecosystem service values to estimate the welfare effects of ecosystem change at this larger geographic scale.

This article, written by Ruta Landgrebe and Benjamin Boteler from Ecologic Institute in the theme issue of the German League for Nature, Animal Protection and Environment’s (DNR) newsletter, concerns environmentally harmful EU subsidies in the agricultural and fisheries sectors and argues for continued support for the "greening" of the EU budget, including the elimination of environmentally harmful subsidies for the new seven-year funding period 2014-2020.

In a blog post on the US State Department's "Our Planet" blog, Dominic Marcellino, Fellow at Ecologic Institute US, relates the story of how the village of Ascha in Bavaria went from being completely energy dependent to producing over 100% of its electricity and 50% of its heating needs from renewable energy.
