Responding Together to Global Challenges

T shepherd sustainable systems through times of global development and change, the environmental research community has long drawn on an interdisciplinary skill set. This includes environmental chemistry, biology, physics, materials science, and the engineering pursuits required to translate those advances in fundamental knowledge to tangible benefit for society. This past week, the biannual meeting of the Association of Environmental Engineering and Science Professors (AEESP) convened in Boston, MA, USA under the theme “Responding Together to Global Challenges.” Of particular focus at the meeting was the evolving role of environmental engineers and scientists in the context of climate change. The traditional contributions of the field have been central to the growth of civilizations, ecosystem services, and striving for ecological preservation, but are now called upon to meet the accelerating demands of a climate changed world. These include prediction of novel patterns of precipitation and drought, better and bespoke agricultural practices, water, sanitation, and hygiene (WASH), as well as decarbonization technologies, geochemical impact assessment, climate justice, and sustainable resources and energy. Innovative thinkers from a spectrum of environmental professions and adjacent implementers (e.g., philanthropists, financers, policymakers, utility and infrastructure experts) are needed to support the grand goal of our collective work: protecting human and ecological health while promoting sustainable systems. Indeed, adapting to and mitigating the impacts of climate change are often articulated as the technological and policy challenge of our time. The readership and authors in the ACS Environmental Au community are empowered with the skills required to provide solutions to these challenges, and this new issue contains a collection of four Articles and a Review illustrating key progress in this pursuit.
