First EAAE Webinar on 'Dealing with Extreme Weather in Agriculture'

Goal: The first EAAE Webinar on 'Dealing with Extreme Weather in Agriculture' took place on July 15, 2020.

Background:
Weather extremes threaten global food security and heavily affect rural communities’ livelihoods. The number and magnitude of many perils is expected to increase with climate change putting an additional burden on farmers and the society. To assure a resilient farming systems, insurance solutions have a long tradition in providing payouts to producers suffering from losses.

The here presented results contribute to a better quantitation of climate and weather risks in agricultural production and provide insights into efficient risk management solutions. For that we bring together a multidisciplinary group of speakers from agronomy, economics, climate research, and plant science to shed light on weather risks from different perspectives.

Talks in the Webinar:

Drivers of Crop Yield Failures in Germany (Heidi Webber, Gunnar Lischeid, Michael Sommer, Robert Finger, Claas Nendel, Thomas Gaiser, Frank Ewert)

The Recent Impacts of Anthropogenic Climate Change on Global Agricultural Production (Ariel Ortiz-Bobea, Toby Ault, Carlos Carrillo, Robert Chambers, David Lobell)

Using Historical Weather Data to Price Crop Insurance Revenue Products (Jesse Tack, Barry Barnett, Keith Coble, Jisang Yu)

Prospects for Weather Index Insurance in Europe (Tobias Dalhaus, Willemijn Vroege, Janic Bucheli, Robert Finger)

Moderation: Robert Finger

Large-scale crop yield failures are increasingly associated with food price spikes and food insecurity and are a large source of income risk for farmers. While the evidence linking extreme weather to yield failures is clear, consensus on the broader set of weather drivers and conditions responsible for recent yield failures is lacking. We investigate this for the case of four major crops in Germany over the past 20 years using a combination of machine learning and process-based modelling. Our results confirm that years associated with widespread yield failures across crops were generally associated with severe drought, such as in 2018 and to a lesser extent 2003. However, for years with more localized yield failures and large differences in spatial patterns of yield failures between crops, no single driver or combination of drivers was identified. Relatively large residuals of unexplained variation likely indicate the importance of non-weather related factors, such as management (pest, weed and nutrient management and possible interactions with weather) explaining yield failures. Models to inform adaptation planning at farm, market or policy levels are here suggested to require consideration of cumulative resource capture and use, as well as effects of extreme events, the latter largely missing in process-based models. However, increasingly novel combinations of weather events under climate change may limit the extent to which data driven methods can replace process-based models in risk assessments.
