We explore Tinbergen’s fundamental insight that policymakers need at least as many policy instruments as targets. We extend this idea using a large natural field experiment in water resource management. We use social comparisons and loss-framed messages to help achieve two goals of our partner utility: getting consumers to purchase drought-resistant plants and reducing water use. Our results sh...

An increasing scarcity of water for crop farming and livestock watering among agropastoralists of Mieso in Eastern Ethiopia has largely disrupted their livelihoods. Indigenous water well maintenance and government initiated rainwater harvesting are two important collective actions common among these communities. With the aim of examining collective action institutions in both cases, we collecte...

Using NASA Moderate Resolution Imaging Spectroradiometer aerosol optical depth and total cloud cover retrievals, CloudSat-CALIPSO cloud profiles, and a database of extratropical cyclones and frontal boundary locations, relationships between changes in aerosol optical depth and cloud cover in extratropical cyclones occurring over Northern Hemisphere oceans are examined. A reanalysis data set is ...

This paper studies Canberra households’ and businesses’ willingness to pay (WTP) to avoid drought water restrictions, using stated choice experiments. We find that customers evidence a lack of WTP to avoid most types of drought-induced restrictions. Respondents appear unwilling to pay to avoid low-level restrictions at all and to avoid higher levels of restrictions that are not in place every d...

the selection of high yielding and stress tolerance plant genotypes with the highest water use efficiency and productivity is one of the most important tools for field water management in arid and semi-arid regions. this study was conducted to identify drought tolerant flax families with the highest irrigation water productivity (iwp) among a population of 119 f3 families derived from a cross b...

Shallow water models are widely used to describe and study free-surface water flow. Even though, in many practical applications the bottom friction does not have much influence on the solutions, the friction terms will play a significant role when the depth of the water is very small. In this paper, we study the Saint-Venant system of shallow water equations with friction terms and develop a we...

Years of research have called for more science to be integrated into water management decisions and for a shift from supply-side to demand-side management; yet, there remains a strong emphasis on supply-side approaches and in many areas limited attention to hydrological data. A survey and interviews with decision-makers in western North Carolina reveal that there is only low-level concern about...
