“…As part of the hydrologic cycle, there are several factors affecting a plant's transpiration rate and therefore ET. These include CO 2 (Hatfield et al 2011), temperature (Allen et al 2003, relative humidity (Bandyopadhyay et al 2009) and wind speed (He et al 2013), amongst others. The level of NO 3 in tile drainage is affected by mineralization-immobilization processes in the soil, which are closely tied to temperature (Melillo et al 2002) and elevated CO 2 (Reich and Hobbie 2012).…”

The effect of climate change on crop production and nitrate-nitrogen (NO3-N) pollution from subsurface drained fields is of a great concern. Using the calibrated and validated RZWQM2 (coupled with CERESMaize and CROPGRO in DSSAT), the potential effects of climate change and elevated atmospheric CO2 concentrations (CO2) on tile drainage volume, NO3-N losses, and crop production were assessed integrally for the first time for a corn-soybean rotation cropping system near Gilmore City, Iowa. RZWQM2 simulated results under 20-year observed historical weather data (1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009) and ambient CO2 were compared to those under 20-year projected future meteorological data (2045)(2046)(2047)(2048)(2049)(2050)(2051)(2052)(2053)(2054)(2055)(2056)(2057)(2058)(2059)(2060)(2061)(2062)(2063)(2064) and elevated CO2, with all management practices unchanged. The results showed that, under the future climate, tile drainage, NO3-N loss and flow-weighted average NO3-N concentration (FWANC) increased by 4.2 cm year−1 (+14.5 %), 11.6 kg N ha−1 year−1 (+33.7 %) and 2.0 mg L−1 (+16.4 %), respectively. Yields increased by 875 kg ha−1 (+28.0 %) for soybean [Glycine max (L.) Merr.] but decreased by 1380 kg ha−1(−14.7 %) for corn (Zea mays L.). The yield of the C3 soybean increased mostly due to CO2enrichment but increased temperature had negligible effect. However, the yield of C4 corn decreased largely because of fewer days to physiological maturity due to increased temperature and limited benefit of elevated CO2 to corn yield under subhumid climate. Relative humidity, short wave radiation and wind speed had small or negligible impacts on FWANC or grain yields. With the predicted trend, this study suggests that to mitigate NO3-N pollution from subsurface drained corn-soybean field in Iowa is a more challenging task in the future without changing current management practices. This study also demonstrates the advantage of an agricultural system model in assessing climate change impacts on water quality and crop production. Further investigation on management practice adaptation is needed.

“…This has been confirmed in the majority of studies examining the response of crops and weeds to increasing levels of CO 2 . However, the physiological characteristics of crops and weeds being either a C 3 or C 4 plant will also determine their respective responses to CO 2 (Hatfield et al 2011;Ziska 2011). While CO 2 is mainly expected to influence crop-weed competition, the most likely effect of a rising temperature is the northwards expansion of native and invasive weed species (Hatfield et al 2011).…”

Agriculture in the twenty-first century faces the challenge of meeting food demands while satisfying sustainability goals. The challenge is further complicated by climate change which affects the distribution of crop pests (intended as insects, plants, and pathogenic agents injurious to crops) and the severity of their outbreaks. Increasing concerns over health and the environment as well as new legislation on pesticide use, particularly in the European Union, urge us to find sustainable alternatives to pesticide-based pest management. Here, we review the effect of climate change on crop protection and propose strategies to reduce the impact of future invasive as well as rapidly evolving resident populations. The major points are the following: (1) the main consequence of climate change and globalization is a heightened level of unpredictability of spatial and temporal interactions between weather, cropping systems, and pests; (2) the unpredictable adaptation of pests to a changing environment primarily creates uncertainty and projected changes do not automatically translate into doom and gloom scenarios; (3) faced with uncertainty, policy, research, and extension should prepare for worst-case scenarios following a "no regrets" approach that promotes resilience vis-à-vis pests which, at the biophysical level, entails uncovering what currently makes cropping systems resilient, while at the organizational level, the capacity to adapt needs to be recognized and strengthened; (4) more collective approaches involving extension and other stakeholders will help meet the challenge of developing more robust cropping systems; (5) farmers can take advantage of Web 2.0 and other new technologies to make the exchange of updated information quicker and easier; (6) cooperationThe views expressed by Stephen R. H. Langrell are purely his own and may not in any circumstances be regarded as stating an official position of the European Commission.

“…For instance, in an influential article, Sen (1981, p. 449) discusses the Ethiopian and Bangladeshi famines of the early 1970s and weather (droughts and floods, respectively), and points out that in both cases farmers were disproportionally affected: "The farming population faced starvation, because their own food output was insufficient, and they did not have the ability to buy food from others, as food output is also their source of income." Food output is also negatively impacted by extreme temperature, as shown by Hatfield et al (2011). Wheeler et al (2000) find that crops are especially at risk when extreme temperatures take place near or during their pollination phase, while Prasad et al (2006) document the adverse impact of extreme temperatures on crop yields.…”

Using data for all 2,454 municipalities of Mexico for the period 1980-2010, this paper analyzes the relationship between exposure to extreme temperatures and precipitation and death, as well as the relationship between severe weather and agricultural income and crop production in the country. It is found that extreme heat increases mortality, while the health effect of extreme cold is generally trivial. Precipitation extremes seem to affect the agricultural system, but their impact on mortality is ambiguous. More specifically, exchanging one day with a temperature of 16-18 °C for one day with temperatures higher than 30 °C increases the crude mortality rate by 0.15 percentage points, a result robust to several model specifications. It is also found that the extreme heat effect on death is significantly more acute in rural regions, leading to increases of up to 0.2 percentage points vis-à-vis a 0.07-point increase in urban areas. The timing of climate extremes is relevant: if a weather shock takes place during the agricultural growing season, the effects on mortality and agricultural output, productivity, prices, and crop yields are large and significant, but not so if such shocks occur during the non-growing season.
