The workshop was conducted from 10-14 December, 2012 at the International Potato Center, Lima, Peru. It was jointly funded by the research programs on Roots, Tubers, and Banana (RTB) and on Climate Change, Agriculture and Food Security (CCAFS). The workshop successfully linked scientists from CG-...

In this study, the adequacy of the late blight simulation model LATEBLIGHT (version LB2004) was evaluated under Nicaraguan conditions. During 2007 to 2008, five field experiments were conducted in three potato-production regions in northern Nicaragua. Two susceptible (‘Cal White’ and ‘Granola’) a...

Currently there is no effective mechanism for measuring the potential benefits of integrated pest and disease interventions in terms of reducing pesticide risks in potato production in developing countries. The environmental impact quotient (EIQ), a composite hazard indicator, was applied to data...

Climate change has a number of observed, anticipated, or possible consequences on crop health worldwide. Global change, on the other hand, incorporates a number of drivers of change, including global population increase, natural resource evolution, and supply demand shifts in markets, from local ...

Process-based ecological models used to assess organisms' responses to environmental conditions often need input data at a high temporal resolution, e.g., hourly or daily weather data. Such input data may not be available at a high spatial resolution for large areas, limiting opportunities to use...

The impacts of climate change on ecosystem services are complex in the sense that effective prediction requires consideration of a wide range of factors. Useful analysis of climate-change impacts on crops and native plant systems will often require consideration of the wide array of other biota t...
