“…In addition to these broader environmental concerns, climate change is expected to increase the severity and frequency of crop and animal diseases as well as inducing greater extremes in weather, primarily through increased flooding and drought events (Melillo et al, 2014). These more extreme and variable weather events will likely exacerbate current problems associated with agricultural production in the region, primarily increasing water pollution from sediment loading and fertilizer transport (Broussard and Turner, 2009;Broussard et al, 2012) and is likely to negatively impact crop yields (Takle et al, 2013;Chhetri et al, 2010;Gustafson et al, 2015). Greater diversity of cropping systems may help reduce risks associated with increased weather variability due to climate change and may also drive greater landscapescale resilience (Aguilar et al, 2015;Gaudin et al, 2015) while balancing multiple goals of "productivity, profitability, and environmental health" (Davis et al, 2012, p. e47149) at the field and landscape scale.…”

Cropping system diversity can help build greater agroecosystem resilience by suppressing insect, weed, and disease pressures while also mitigating effects of extreme and more variable weather. Despite the potential benefits of cropping systems diversity, few farmers in the US Corn Belt use diverse rotations. This study examines factors that may influence farmers' decisions to use more diversified crop rotations in the US Corn Belt through a parallel convergent mixed methods approach, using a multi-level analysis of Corn Belt farmer survey data (n = 4,778) and in-depth interviews (n = 159). Analyses were conducted to answer questions regarding what factors influence farmers' use of extended crop rotations in intensive corn-based cropping systems and to explore whether farmers in the Corn Belt might use extended crop rotations in response to climatic changes. Findings suggest that path dependency associated with the intensive corn-based cropping system in the region limits farmers' ability to integrate more diverse crop rotations. However, farmers in more diversified watersheds, those who farm marginal land, and those with livestock are more likely to use extended rotations. Additionally, farmers who currently use more diverse rotations are also more likely to plan to use crop rotations as a climate change adaptation strategy. If more diverse cropping systems are desired to reduce climate risks, in addition to reducing the negative impacts associated with industrial agricultural production, then further efforts must be made to facilitate more diverse crop rotations in the U.S. Corn Belt. This may be achieved by adjusting policy and economic incentives that presently discourage cropping system diversity in the region.

“…Their response between countries (Lobell and Gourdji, 2012). Climate science forecasts a shift towards higher temperatures that are punctuated by unpredictable episodes of extreme weather with increasing frequency and intensity globally (Field et al, 2012;Rosenzweig et al, 2014;Gustafson et al, 2016), in central Europe and in the CZ (Brázdil et al, 2012;Huth et al, 2015). These changes could impact crop yields considerably and may require transformations of agricultural systems in the upcoming decades to sustain accessible and good production (Moore and Lobell, 2015).…”

“…In addition to the current assortment of vegetables that are grown under the present‐day climate, non‐traditional vegetables could also be grown in open field conditions. Thus, experiments should be performed with crops that are currently grown infrequently in the area but that could become important under future climate and market environments (Gustafson et al , ).…”

The response of field‐grown vegetables to adverse weather conditions is strongly coupled to the timing of adverse events, the sensitivity of the growth stage of the impacted crop and the management actions that are taken. To estimate the long‐term yield response to changes in temperature and precipitation as well as the short‐term response to key adverse weather events (e.g. heavy precipitation, drought and heat stress) on the yields of vegetable crops, we used several statistical approaches with six daily impact‐indicators, the four monthly drought indices and the climate trends. Our study integrated a newly available historical yield dataset at the district level (the finest spatial resolution) for all highly marketable vegetables (celeriac, late carrots, root parsley, early kohlrabi, summer savoy cabbage, late cauliflower, late cabbage, onions, green peas, tomatoes, salad and pickling cucumbers) and a high‐resolution historical climate dataset (seven daily meteorological variables at a 10 × 10 km resolution) over a 54‐year period in the Czech Republic (CZ). Different indices were used to reflect different dimensions of water and heat stress, which have different impacts on vegetable growth and yield. We find positive long‐term impacts of recent warming on fruiting vegetables (from 4.9 to 12.2% °C−1) but decreases in the yield stability of traditionally grown root vegetables in the warmest areas of the country. Short‐term extreme temperature variabilities (days with heat stress) were found to be the dominant type of adverse event for tomato and cucumber production due to its effect on increased soil water demand, which increased transpiration rates, whereas changes in both the diurnal temperature ranges and minimum temperature (Tmin) were associated with minimal risk of frost damage. Brassicas vegetables are widely irrigated in the CZ, but irrigation does not fully mitigate drought effects; hence, short‐term extreme precipitation variability largely controls crop production in the growing districts. The high frequencies of dry days and days with heavy precipitation within the critical growth stages of brassicas reflect a competition between more dry days and greater precipitation intensity on wet days. The yield variability of bulbs is largely explained by both short‐term extreme precipitation and temperature variability (drought‐heat stress), which reflects the predominantly rain‐fed system of onion cultivation. Both drought and heat stress and changes in Tmin were important in explaining yield losses of root vegetables. Legumes had the lowest risk of multiple stresses during their short growth cycle, but droughts remain the dominant type of adverse event. Years with yield gains were substantially more common than years with yield losses for brassicas, bulbs and legumes vegetables in all of the cultivated regions.
