Abstract:The impact of climate change on Swiss maize production is assessed using an approach that integrates a biophysical and an economic model. Simple adaptation options such as shifts in sowing dates and adjustments of production intensity are considered. In addition, irrigation is evaluated as an adaptation strategy. It shows that the impact of climate change on yield levels is small but yield variability increases in rainfed production. Even though the adoption of irrigation leads to higher and less variable maiz… Show more

“…We use quasi-experimental data derived for maize production at the Swiss Plateau simulated with deterministic crop yield simulation model CropSyst, derived from Finger et al (2011) andFinger (2012). In CropSyst, above-and below-ground processes such as the soil water budget, soil-plant nitrogen budget, crop phenology, canopy and root growth, and crop yield are simulated in response to crop and soil characteristics, daily weather data, and management options (see Stöckle et al, 2003, for details).…”

“…Studies of this type manage to provide quantitative estimates of future consequences for the productivity and other agricultural services, the main focus being essentially to adapt management based on given growing conditions (e.g., planting dates or grazing periods based on soil moisture) in order to counter anticipated risks or to realize any benefits. Though process-based simulation models have been applied for climate change and adaptation studies in agriculture (Finger et al, 2011;Graux et al, 2013;Kristensen et al, 2011;Smith and Olesen, 2010;Trnka et al, 2010;White et al, 2011), answering the question "Are agricultural systems expected to become more vulnerable (and why) owing to climate changes" still requires quite some research.…”
Farmers should increasingly adopt more water‐efficient irrigation technologies—such as drip irrigation—as a result of climate warming and aggravating water scarcity. We analyze how Italian farmers adapt to climate change by changing their irrigation technology mix. We apply a two‐stage econometric model to data from 5876 Italian farms. We find that farmers' initial reaction to increasing temperatures is reducing their surface‐irrigated fractions. When temperatures increase further, farmers switch toward more sprinkler irrigation. Our results show that farmers are not autonomously moving to drip irrigation in response to climate change, suggesting that government incentives are needed to encourage this transition.
