Climate Impacts Associated With Reduced Diet Diversity In Children Across Nineteen Countries, Meredith T. Niles, Benjamin F. Emery, Serge Wiltshire, Molly E. Brown, Brendan Fisher, Taylor H. Ricketts
Climate Impacts Associated With Reduced Diet Diversity In Children Across Nineteen Countries, Meredith T. Niles, Benjamin F. Emery, Serge Wiltshire, Molly E. Brown, Brendan Fisher, Taylor H. Ricketts

It is widely anticipated that climate change will negatively affect both food security and diet diversity. Diet diversity is especially critical for children as it correlates with macro and micronutrient intake important for child development. Despite these anticipated links, little empirical evidence has demonstrated a relationship between diet diversity and climate change, especially across large datasets spanning multiple global regions and with more recent climate data. Here we use survey data from 19 countries and more than 107 000 children, coupled with 30 years of precipitation and temperature data, to explore the relationship of climate to child diet diversity while …
Water Use Governance In A Temperate Region: Implications For Agricultural Climate Change Adaptation In The Northeastern United States, Rachel E. Schattman, Meredith T. Niles, Hannah M. Aitken
Water Use Governance In A Temperate Region: Implications For Agricultural Climate Change Adaptation In The Northeastern United States, Rachel E. Schattman, Meredith T. Niles, Hannah M. Aitken

Climate change and access to water are interrelated concerns for agriculture and other sectors, even in temperate regions. Governance approaches and regulatory frameworks determine who has access to water, for what purpose, and when. In the northeastern United States, water governance has historically been conducted by states through a combination of statutory guidance and common law. However, it is unclear what effect if current governance approaches will be sufficient for achieving resource conservation and equitable allocation in a changing climate. To provide insight into these issues, we conducted the first review of freshwater governance in the 12 states that comprise …
Smallholder Farmers Spend Credit Primarily On Food: Gender Differences And Food Security Implications In A Changing Climate, Marissa Carranza, Meredith T. Niles
Smallholder Farmers Spend Credit Primarily On Food: Gender Differences And Food Security Implications In A Changing Climate, Marissa Carranza, Meredith T. Niles
College of Agriculture and Life Sciences Faculty Publications
In many low-income nations agriculture is used as the primary source of income, which in the face of a changing climate, is known to be at considerable risk for the smallholder farmers that rely on it. Financial resources may enable smallholder farmers to implement adaptation practices and diversify income and investments, which has the potential to affect household income and food security. Here we explore relationships between access to different types of financial resources among male and female-headed households and women vs. men, use of financial resources, and its relationship to food security. We use data from the CGIAR Climate …
A Comparative Analysis Of Governance And Leadership In Agricultural Development Policy Networks, Jessica Rudnick, Meredith Niles, Mark Lubell, Laura Cramer
A Comparative Analysis Of Governance And Leadership In Agricultural Development Policy Networks, Jessica Rudnick, Meredith Niles, Mark Lubell, Laura Cramer
College of Agriculture and Life Sciences Faculty Publications
Agricultural development initiatives feature many public and private organizations working together across sectors and scales to pursue the goals of food security and climate resilience. Policy networks are considered a crucial ingredient for the learning and cooperation needed to effectively implement agricultural development projects and increase community resiliency, yet very little comparative empirical data has been collected to assess where and how these networks operate. We contribute to filling this gap by characterizing the governance and leadership patterns within agricultural development policy networks that connect organizations working on climate resilience and food security activities in 14 smallholder farming communities across …
Does Household Capital Mediate The Uptake Of Agricultural Land, Crop, And Livestock Adaptations? Evidence From The Indo-Gangetic Plains (India), Sameer H. Shah, Courtney Hammond Wagner, Udita Sanga, Hogeun Park, Lia Helena Monteiro De Lima Demange, Carolina Gueiros, Meredith T. Niles
Does Household Capital Mediate The Uptake Of Agricultural Land, Crop, And Livestock Adaptations? Evidence From The Indo-Gangetic Plains (India), Sameer H. Shah, Courtney Hammond Wagner, Udita Sanga, Hogeun Park, Lia Helena Monteiro De Lima Demange, Carolina Gueiros, Meredith T. Niles

Farmers in the Indo-Gangetic Plains produce much of the wheat and rice grown in India. However, food production and millions of farm-based livelihoods in this region will continue to be adversely affected by hydro-climatic change and variation, reduced land productivity, and declining groundwater levels. Thus, agricultural adaptations are essential for protecting and improving upon intersecting goals of food security, poverty alleviation, and wellbeing. Household “capital” (e.g., natural, human, financial, physical, and social) is commonly cited as an indicator of livelihood adaptability and innovation. We develop a series of mediated structural equation models to empirically evaluate the validity of capital as …

Impacts Of Projected Climate Change Over The Lake Champlain Basin In Vermont, Justin Guilbert, Brian Beckage, Jonathan M. Winter, Radley M. Horton, Timothy Perkins, Arne Bomblies

The Lake Champlain basin is a critical ecological and socioeconomic resource of the northeastern United States and southern Quebec, Canada. While general circulation models (GCMs) provide an overview of climate change in the region, they lack the spatial and temporal resolution necessary to fully anticipate the effects of rising global temperatures associated with increasing greenhouse gas concentrations. Observed trends in precipitation and temperature were assessed across the Lake Champlain basin to bridge the gap between global climate change and local impacts. Future shifts in precipitation and temperature were evaluated as well as derived indices, including maple syrup production, days above …
Land Use Adaptation To Climate Change: Economic Damages From Land-Falling Hurricanes In The Atlantic And Gulf States Of The Usa, 1900-2005, Asim Zia
College of Agriculture and Life Sciences Faculty Publications
Global climate change, especially the phenomena of global warming, is expected to increase the intensity of land-falling hurricanes. Societal adaptation is needed to reduce vulnerability from increasingly intense hurricanes. This study quantifies the adaptation effects of potentially policy driven caps on housing densities and agricultural cover in coastal (and adjacent inland) areas vulnerable to hurricane damages in the Atlantic and Gulf Coastal regions of the U.S. Time series regressions, especially Prais-Winston and Autoregressive Moving Average (ARMA) models, are estimated to forecast the economic impacts of hurricanes of varying intensity, given that various patterns of land use emerge in the Atlantic …
The Limits To Prediction In Ecological Systems, Brian Beckage, Louis J. Gross, Stuart Kauffman
The Limits To Prediction In Ecological Systems, Brian Beckage, Louis J. Gross, Stuart Kauffman
College of Agriculture and Life Sciences Faculty Publications
Predicting the future trajectories of ecological systems is increasingly important as the magnitude of anthropogenic perturbation of the earth systems grows.We distinguish between two types of predictability: the intrinsic or theoretical predictability of a system and the realized predictability that is achieved using available models and parameterizations. We contend that there are strong limits on the intrinsic predictability of ecological systems that arise from inherent characteristics of biological systems. While the realized predictability of ecological systems can be limited by process and parameter misspecification or uncertainty, we argue that the intrinsic predictability of ecological systems is widely and strongly limited …
