Key Findings

  • The 2017 heavy rainfalls and flooding impacted farms across New York State
  • Crops grown on clayey soils suffered an estimated 53% loss in crop yield and crops grown on gravelly, sandy or siltier soils suffered estimated crop yield losses of 25% or less
  • In addition to yield losses, 95% of farmers said the quality of their crop was negatively impacted
  • 30% of farmers said they would have increased their drainage infrastructure, including adding tiling and drainage ditches, if they had known how wet 2017 would be

A wet spring, followed by higher than average precipitation and heavy rainfall events (e.g. the heaviest 1% of all daily rainfall events) during the 2017 growing season (NRCC) led to saturated soils and flooding on many farms throughout New York State (NY). The frequency of heavy rainfall events have already increased by 71% in NY over the last half century (NCA 2014), and this trend is predicted to continue in the future (Wuebbles et al. 2014). Given this, and to get a sense of how farmers were affected by these conditions, as well as how they coped, we surveyed farmers across NY State throughout September of 2017. The survey was distributed online and in paper format with help from Cornell Cooperative Extension, The Farm Bureau, and New York State Department of Agriculture & Markets. A majority of the 45 farms in 24 counties were in areas of the state that experienced the heaviest rainfalls, and we had fewer responses from farms in the Adirondacks region and southeastern part of the state, where heavy rains and flooding were less prevalent (Fig. 1).

Heavy rainfall and flooding impact

Fig. 3. Response to the survey question “How important are these issues {listed on figure} related to heavy rainfalls in 2017 in terms of economic impact on your farm?”. Figure shows percent of farmers rating the issues as (a) extremely + very important, (b) fairly + somewhat important, and (c) not important.

Of the farmers surveyed, those with heavier clay soils estimated crop yield losses of 53%. More gravelly soils led to lesser yield losses (17%), and for crops grown on siltier or sandier soils farmers estimated yield losses of 22 to 25%. Vegetable, field, and fruit crops suffered estimated yield losses of 38%, 32%, and 24%, respectively (Fig. 2). Importantly, 95% of farmers said the quality of their crop was negatively impacted by issues related to the heavy rainfalls in 2017 (see Fig. 3 for list of ‘issues’).

When asked what the economic impact of the heavy rainfalls was on their farm, 80% of farmers said it was either “moderate” or “severe”, 17% said it was “minor”, and 3% said the heavy rainfalls were merely a “nuisance” and had almost no economic impact. In rating the importance of various issues related to heavy rainfalls in 2017 in terms of economic impact on their farm, over half of the farmers rated saturated soils and field flooding, delays in or inability to plant or harvest, inability to use equipment, lack of field access, and crop disease as “extremely or very” important (Fig. 3).

Adaptive capacity

82% of farmers said they use drainage ditches or drainage tile to help deal with heavy rainfalls, yet over half of farmers said they did not have enough infrastructure and/or equipment to deal with heavy rainfalls. Further, 70% of farmers said the 2017 heavy rainfalls led to the recognition of weaknesses or limitations in the infrastructure on their farm, particularly in relation to manure management and drainage infrastructure. And when asked what they would have done differently if they had known how wet 2017 would be there was a variety of responses (Fig. 4). Nearly 1/3rd of farmers said they would have expanded their drainage capacity (e.g. more drainage tiles and ditches, etc.). Nineteen percent would have changed their fertilizer, herbicide, or pesticide application timing, and another 10% would have adopted better soil health practices, such as using cover crops, reducing tillage, and using composts or mulches.

We also gave farmers a list of soil health practices and asked them to tell us if, for the ones they use on their farm, any of them lessened the impact of heavy rainfalls in 2017 (Fig. 5). Aside from “the use of mulches”, which 67% of farmers said did not help them, a vast majority said other soil health practices did help. Over 70% of farmers said that practices such as “use of winter cover crops”, “reduced tillage”, “use of composts or manure”, “leaving crop residues”, and/or “changing crop rotations” did lessen the impact of the very wet 2017 season.

any soil health practices you have adopted on
your farm lessen the impact of heavy rainfalls
in 2017?”.

Over half of the farmers reported experiencing issues on their farm related to heavy rainfalls or flooding every 1 to 4 years. The other 46% reported this occurrence rarely or only every 5 to 6 years. While climate projections for NY indicate that we are likely to expect more heavy rainfall events, as well as more short-term summer droughts in the future (NCA 2014, Wuebbles et al. 2014, Sweet et al. 2017), our survey results suggest that, though farmers were concerned about the impacts of these events in the future, they are not as convinced that these events will occur more frequently in the future. For instance, 49% of farmers said they were “extremely or very” concerned that heavy rainfalls and flooding will negatively impact their farms in the future. Yet, only 38% said they were similarly concerned that such events may occur more frequently in the future (Fig. 6). Also, given the drought in 2016 (Sweet et al. 2017), we asked farmers a similar series of questions pertaining to drought. Though 31% of farmers were “extremely or very” concerned that drought may negatively impact their farm in the future, only 24% were concerned that drought may occur more frequently in the future.

With climate change, NY farmers are likely to continue facing unique challenges related to both increased heavy rainfall events as well as short-term summer droughts. Resource managers and planners, engineers, researchers, extension agents, NGO’s and other farm-support organizations need to prepare to help farmers adapt to and become more resilient to an uncertain future. Information collected from farmers about how they might adapt to future climatic events suggests there could be potentially dramatic consequences not only for farmer livelihoods and food production, but also for NY natural resources. For example, certain adaptation practices could impact downstream water quality and availability.

Based on our survey results, here are some ideas farmers had on how the above mentioned organizations might help farmers better prepare for and cope with heavy rainfalls events in the future:

  • Low-cost loans or ‘in kind’ grants to help with costs of improving drainage (e.g. drainage ditches and tiles)
  • Continued education on nutrient management planning
  • Advice on how to increase soil organic matter for improved drainage capacity
  • Information about cropping options and strategies to cope with heavy rainfalls
  • Lower cost and better fungicides for wet years
  • Increased town drainage (e.g. more funding for ditch digging and for clearing debris out of ditches)
