To address environmental issues, society needs a deeper understanding of the natural world, and the ways we can regulate our own behavior.Faculty and students at F&ES conduct research in eight broadly conceived areas of environmental concern – biodiversity, forestry, global climate, industry, law and economics, urban systems, water, and social ecology. The scope of these programs reflects not just the complexity of human interaction with the environment, but the fact that the easy answers have been exhausted. As such, it is the mission of the F&ES faculty and students to conduct research that uncovers new knowledge, unique insights, and approaches that tie many fields together. This mission is further carried out by communicating the results of this research to the widest possible audience through publication, lectures, and other educational programs.

PI: Lisa Dale
Sponsor: Council of Western State Foresters $29,149
Summary: CWSF is interested in understanding actions underway in member states to both mitigate and adapt to climate change. Improved fluency on the state of play across the West provides an opportunity to highlight the critical role played by forestry in the evolving climate change discussion. Products developed by the YCELP team will empower Western state foresters and the Council to be centrally positioned in the climate change conversation, and will amplify the voice of foresters across the West.
Mobilizing Climate Change Adaptation Knowledge through Global and Regional Networks
PI: Lisa Dale
Sponsor: United Nations Environment Programme (UNEP) Division of Enviornment Policy Implementation, Kenya $20,000
Summary: The Paris Agreement raised the political profile of climate resilience. There is now a global goal for climate change adaptation and it is recognized that adaptation represents a challenge with local, national and international dimensions. The UN Climate Resilience Initiative: Anticipate, Absorb, Reshape, known as A2R, is a global, UN led, multi-stakeholder initiative that seeks to strengthen climate resilience for vulnerable countries and people. It will bring together governments, international agencies, regional initiatives, the private sector, civil society and researchers. The initiative seeks to accelerate action on key aspects of climate resilience under its three pillars:
Support to the 1 Gigaton Coalition
PI: Angel Hsu
Sponsor: United Nations Environment Programme (UNEP) $216,171
Summary: The 1 Gigaton Coalition supports platforms to measure and report GHG emission reductions resulting from renewable energy and energy efficiency programs so that these contributions are recognized and counted. The Coalition focuses on cooperation between countries and on bringing developing countries’ impacts to light. This voluntary international framework focuses on programs that are not fully understood due to a lack of quantifiable information to assess their impact –these often-overlooked activities will save an estimated 1 GtCO2e by 2020. Yale University prepared the inaugural report of the 1Gt Coalition presented in December 2015 at the Paris COP. The objective of this project is to support the 1 Gt Coalition in defining and preparing its second report due in November 2016. The support includes the selection of topics for inclusion in the second report of the coalition and the preparation of that report.
Urban Growth, Land-Use Change, and Growing Vulnerability in the Greater Himalaya Mountain Range Across India, Nepal, and Bhutan
PI: Karen Seto
Sponsor: National Aeronautics and Space Administration $749,815
Summary: Home to about 210 million people and extending over eight countries, the Hindu Kush Himalayan (HKH) region is at the confluence of two major trends that together are transforming one of the most dynamic mountain systems in the world. First, the region is a hotspot for four natural hazards: earthquakes, fires, floods, and landslides. Over the past few years, the HKH region has experienced a number of devastating natural disasters, including a 7.5 magnitude Pakistan-Afghanistan earthquake in 2015, a glacial lake outburst flood in northern Bhutan in 2015, floods in Uttarakhand in 2013 that left nearly 6,000 dead and more than 100,000 people trapped, and the 7.8 magnitude earthquake in Nepal in 2015, that killed more than 9,000 people and injured more than 23,000. Second, the HKH region is rapidly urbanizing. Fueled by migration from rural areas, valleys and plains, the growth of religious, ecological and adventure tourism, and recent social unrest, towns and urban centers are expanding. Although the region is still predominantly agrarian, migration to urban centers is increasingly an important livelihood strategy for rural households, and non-farm income is an increasing component of household incomes. As recently as 1981, less than 10% of the Himalayan population lived in a town or city. By 2000, the urban population in the region had doubled to 20%. The growing urban population, an urbanizing economy, and associated land use and land cover changes are transforming the Himalayas. Construction of buildings, deep roadcuts in steep hillsides, and unplanned urban development, all of which require cutting into bedrock or crossing geologically weak areas, have resulted in increased and more severe occurrences of hillside collapse, landslides, debris flows, rock slides, putting millions of people at risk.
Yet despite the vulnerability of the region and its people, the 2015 Nepal earthquake highlighted the lack of accurate and up-to-date information about urban settlements in the region and those most at risk in this coupled social-environmental system. The proposed research aims to fill these knowledge gaps by using multi-scale and multi-source satellite data applied to the Turner et al. (2003)and Luers et al. (2003)vulnerability frameworks to answer five inter-related research questions about the HKH region:
The proposed research includes three important innovations: to analyze urban change and associated land-use dynamics in a multi-country framework, to examine multiple dimensions of vulnerability, and to examine a contiguous geographic region that covers approximately 1.289 million km2 with the goal of capturing all types and sizes of urban settlement change. This approach is a marked departure from most other studies that focus solely on a few capital or large cities and their immediate surroundings. Through a coordinated research strategy that interweaves the entire Landsat TM time series for 41 scenes, high resolution commercial imagery from Quickbird and WorldView 1, 2, and 3, analysis of socioeconomic data related to sensitivity, and fieldwork, the project will quantify and map the vulnerability of the HKH region to different stressors.
EAGER: Preparing the Yale Metal Life Cycles Database for Global Distribution
PI: Tom Graedel; Co-PI: Barbara Reck
Sponsor: National Science Foundation $233,784
Summary: Databases that result from academic research activities are increasingly deposited in accessible archives for the purpose of making them available for use by institutions and governments worldwide. These data are static, however – they have no provision for updating and enhancement nor the assurance of archive security and long-term preservation. In the case of material flow information, essential to the evaluation of metal use, recycling, import/exports flows, and losses to the environment, quantitative life cycle results have been published for some sixty elements, but rarely with the supporting information being publicly available and/or the detailed underlying and generated data available in a user-friendly format. Nonetheless, these cycles form the foundations for subsequent research related to materials sustainability, product lifetimes, international trade, carbon emissions, and many related topics. From this perspective, the present proposal seeks the necessary resources to fully document and transform the Yale archive of data on all aspects of materials sustainability for numerous metals and metalloids from its present form into a convenient, easily-accessed, and well-documented package. It will then be transferred to the U.S. Geological Survey for data formatting review, quality assessment, achieving, security, updating enhancement, and accessibility.
DISSERTATION RESEARCH: The functional consequences of antagonism in fungal communities
PI: Dan Maynard (Mark Bradford, faculty advisor)
Sponsor: National Science Foundation $21,543
Summary: Dissertation research completed thus far directly links microbial trait expression to competitive ability and functional ability, suggesting that antagonistic interactions alter ecosystem function in ways that challenge traditional ecosystem models and ecological theory. In previously established field and laboratory experiments, microbial community composition explained a larger proportion of variability in ecosystem function than environmental conditions, highlighting the need to better understand how species interactions and community structure alters environmental function. The PIs propose to expand their research to obtain three primary objectives: (1) develop a generalizable model for incorporating competitive network structure into traditional biodiversity-function experiments; (2) use this model to quantify how microbial combative interactions and competitive network structure alter ecosystem function; (3) determine how competitive intransitivity and combative interactions affect spatial structure and realized diversity of antagonistic communities.
Additive Manufacturing and the Environment: A Special Issue of the Journal of Industrial Ecology
PI: Reid Lifset
Sponsor: United States Department of Energy $66,512
Summary: Additive manufacturing, best known to the public as 3-D printing, is a rapidly developing technology that holds out the promise of new capabilities and innovation in a wide variety of industries. Because the core process is additive, in many cases, there is less waste—because no cuttings or grindings are produced as occurs in conventional machining processes. AM sidesteps creation of molds and related manufacturing process, allowing production in response to actual demand, rather than forecast, demand. AM also facilitates localized production. 3-D printers in homes and small businesses can be used to make objects one-at-a-time using software readily available via the Internet, avoiding the need to ship the final product to the user.
As with any new technology, AM presents environmental opportunities and challenges. The opportunities include reduction of transport due to localized production, increased availability of spare parts, avoidance of excess production and inventory, decreased waste, and decentralized production creating the opportunity for diverse members of society to participate in design and manufacturing. Challenges include the environmental footprint of raw materials, occupational health and safety issues, challenges to recycling, and increased shipping of raw materials to diverse locations.
While there is an extensive literature on the manufacturing aspects of AM, research on the environmental dimensions of additive manufacturing is more limited, largely focusing on energy consumption of machining and related unit processes. Nascent literatures on particulate and gaseous emissions from additive processing and life cycle assessment of AM are emerging. The literatures are largely disconnected and not linked to scenarios regarding the potential environmental advantages of additive manufacturing. The special issue aims to catalyze research and analysis and exchange across disciplines and literatures.
The Journal of Industrial Ecology, a peer-reviewed international bimonthly journal, owned by Yale University and published by Wiley-Blackwell, seeks funding for the publication of a special issue on environmental dimensions of additive manufacturing.
