Civil unrest and political instability have been associated with endangered species poaching. This paper accounts for a period of civil unrest in Assam, India, which saw a marked increase in rhino poaching. Census data on the greater one-horned rhinoceros (Rhinoceros unicornis) in the Kaziranga...

The grapevine leafroll disease (GLRD) threatens grape harvests in the United States and the world. This viral disease reduces yield, delays fruit ripening, and affects wine quality. The disease ecology is still under study and the spatial-dynamics of the spread process remains poorly understood....

Research on climate change in recent decades has disproportionately focused on predicting impacts while largely ignoring adaptation strategies. How agricultural systems can adapt to minimize the uncertainty caused by rising temperatures is one of the most important research issues today. We...

Grapevine leafroll disease (GLRD) presently threatens the grape and wine industry worldwide. We develop a cellular automata model of GLRD diffusion and control in two ecologically-connected, independently-managed vineyards. One vineyard produces high-value wine grapes whereas the other produces...

Leafroll disease is one of the most important virus diseases of grapevines worldwide. It reduces yields, delays fruit ripening, reduces soluble solids and increases titratable acidity in fruit juice. This study uses a Net Present Value (NPV) approach over a 25-year lifespan of a vineyard to...

What are the costs of increased food system localization in the case of a fresh vegetable product? When production is reallocated across space and seasons, how do supply chain costs and consumer prices change? In this article, we use a production and transportation model to answer these...
