Daugherty Water for Food Global Institute: Faculty Publications
Future freshwater supply, human water demand, and people’s exposure to water stress are subject to multiple sources of uncertainty, including unknown future pathways of fossil fuel and water consumption, and ‘irreducible’ uncertainty arising from internal climate system variability. Such internal variability can conceal forced hydroclimatic changes on multi-decadal timescales and near-continental spatial-scales. Using three projections of population growth, a large ensemble from a single Earth system model, and assuming stationary per capita water consumption, we quantify the likelihoods of future population exposure to increased hydroclimatic deficits, which we define as the average duration and magnitude by which evapotranspiration exceeds precipitation …

Rethinking Our Global Coastal Investment Portfolio, Erin Mccreless, Michael W. Beck
Journal of Ocean and Coastal Economics
Coastal gray infrastructure, including roads, bridges, and buildings, is critical for communities, and we invest significantly in it. We also invest in the restoration and maintenance of coastal green infrastructure such as wetlands and reefs, which provide many services and benefits to human communities. However, the relative scale of financial investments in different coastal sectors – that is, our global coastal investment portfolio – remains poorly understood. We identify some of the major sources of funding for coastal green and gray infrastructure globally, including international aid funds; US public and private funds for coastal conservation, restoration and management; and private …
