Heat & Health

Filed Under: climate change adaptation, health, heat by farmclim — Leave a comment
August 6, 2018

It’s hot.  This summer heat records have been broken across the Northeast from Burlington, Vermont to Portland Maine and Hartford, Connecticut.

In Burlington, Vermont, we’ve just lived through the hottest month since the National Weather Service began keeping records in 1892.  Over the month of July 2018, a new record of 21 days was set for most days above 85 degrees. This surpassed the 20 days in July 1999.  Moreover, 10 days were recorded over 90 degrees F and a new record was set for the warmest night, a night-time low temperature of 80 degrees.

As this summer heat takes its toll on Vermonters, the Vermont Department of Health has been monitoring the effects of heat and has found that people are at greater risk for serious heat-related illnesses when the statewide average temperature reaches 87°F or hotter.  Based on an analysis of historical data, on days reaching 87°F or hotter:

  • Heat-related emergency department visits occurred eight times more frequently
  • ED visits were more common for adults 75 and older and teens/young adults 15-34
  • There was one additional death per day among individuals age 65 and older

While typically we’ve thought of the elderly, sick and the very young as particularly at risk, what stands out in recent analysis is that young adults are particularly vulnerable. Recent research on college students in Boston showed that heat can slow down reaction times and lowered performance on basic arithmetic tests.

When working in the field or at a farmers market, bear this possible cognitive decline in mind.   Vermont Department of Health recommends a number of preventative measures including: –

  • reducing outdoor activity during the hottest part of the day
  • hydrating, and avoiding alcohol and caffeine if possible
  • wearing light-colored and light-fitting clothes
  • seeking relief in air-conditioned spaces or other cool & shady places
  • keeping living spaces cool by using shades, windows, fans, and avoiding use of oven/stove
  • never leaving animals, children, adults with disabilities in a parked vehicle
  • learning the signs and symptoms of heat illnesses and basic first aid responses
  • checking in on colleagues, neighbors and loved ones, especially those living alone

Know the symptoms of heat illnesses such as muscle cramps, weakness, heavy sweating, nausea, vomiting, and dizziness. These symptoms can usually be treated through rest in a cool, shady place and by drinking cool beverages If symptoms do not improve or if confusion or fainting occurs, you should seek immediate medical attention, as heat stroke can result in death

Unfortunately, the end of is not in sight for heat waves.  The number of days reaching a statewide average of at least 87°F is expected to increase in the future due to climate change from 6 days a year (1981-2010 average) to 15 – 20 days by 2050

For any of us working on a farm, avoiding the outdoors is not an option.  So taking breaks to stay hydrated and to cool down in shady areas needs to be made a priority and shifting and alternating schedules so that weeding is done in the earliest part of the day when it’s cooler.

Cover Crops for Climate Smart Farming

Filed Under: climate change adaptation by farmclim — Leave a comment
October 25, 2017

With 100 acres in production and 200 acres in cover crops, Pete’s Greens in Craftsbury, Vermont invests almost more time in managing their cover crops aka “green manures” than they do their marketable crops.  But climate smart farming means caring for soils, keeping carbon in the soil (not the air) where organic matter is a key factor in the production of quality crops.

As farm manager Isaac explains, “This takes a ton of time – we spend a lot of time dealing with our cover crops. You sort of think you plant it and away you go and you come back two years later. Planting soil into sod and getting the sod to die off before you go back into production is really difficult; it’s machinery intensive. So we’ve been doing multiple cover crops on different fields over two seasons. This is our third planting of oats on this field this year so we took straw off of these fields twice and that’s for mulching.”  Isaac uses about 300 lbs of seeds per acre to get the density of oats he wants for green manures.

As soil guru Fred Magdoff confirms in his book Building Soils for Better Crops, “It’s not easy .. Improving organic matter content requires a sustained effort that includes a number of approaches to return organic materials to soils and minimize soil organic matter losses…  All practices that help to build organic matter do at least one of two things – add more organic materials than was done in the past or decrease the rate of organic matter loss from soils.”   Knowing your soil types and rates of aeration and importantly, your starting point for percentage of organic matter will let you know whether your farm is on the trajectory for climate smart farming.

Resilient to Climate, Vermont Farmers Roll with the Weather

Filed Under: climate change adaptation by farmclim — Leave a comment
September 27, 2017

Early rains, late rains. Early blight, late blight. Wet spring, dry fall.  The variability of Vermont weather means one summer’s typical weather is anomalous in the next.

The crop that is amazing one season could be disappointing the next. Summer 2017 made planting schedules difficult as mid-season rains pelted crops and saturated soils when many farmers wanted to be planting. Lester Farm in New Haven had a successful early crop of melons, which ripened well in the sunny dry weeks of early September, but they’ve sold out now earlier than planned.   They’d been expecting to stagger their harvests for a late harvest melon crop but mid-summer heavy rains prevented them from planting their second crop and their melon starts ended up in their compost pile.

Pete’s Greens in Craftsbury, Vermont has also experienced some predicaments due to mid-season rains and early blight this past summer.  Farm manager Isaac describes,

…Fungus, bacteria, stuff coming up from the south, blight is pretty common now in Vermont, something we didn’t deal with for our first eight years… Our potato crop is about 50% of what it usually has been. We got tons of rain early on and lost a bunch of seed when we planted it so those crops suffered.  Our carrot crop which we plant around July 4 is looking amazing, we’ve had some nice warm dry weather and the rain to give it a big boost and it’s looking super…

Overall, climate impacts in the Northeast show increasing precipitation and increased frequency of intense precipitation events. Heavy rains not only cause soil erosion but also can splash back on plants bringing soil-born diseases in contact with leafy vegetables.   Many Vermont farmers cope by planting a diversity of crops and by being nimble in responding to whatever the weather brings.

10-year precipitation trend May-Sept in Northeast VT compared to 30-year mean

 

Farm managers like Isaac have years of experience under their belt so are ready to optimize the resources, crops, green manures, planting and harvesting methods on their fields so that they can continue to meet their expanding regional market for local organic vegetables.

The impacts of climate change have become the back drop to other pressures farmers face including markets, pricing, and pleasing customers. Managing them all is part of the job.

Adapting Farm Management to a Changing Climate: Butterworks Farm – part II

Filed Under: climate change adaptation by farmclim — Leave a comment
July 25, 2017

“Paying attention to the nuances of the land, I’ve learned to grow really high quality forages, protein, and energy.”  Jack and Anne Lazor, Butterworks Farm, raise their herd of Jersey cows on pasture and high-quality forages in Westfield Vermont and produce a certified organic yoghurt.

For most Vermont farmers, the variable weather of summers from the extreme dry summer of 2016 to the wet cool summer of 2017 has proved challenging.   To meet these challenges, Jack considers increasing the organic matter content of agricultural soils as an important strategy to address many of the impacts of climate change.  The farm has doubled the organic matter content of the soils over the past 40 years. This has significant benefits for water infiltration during times of extreme precipitation, while maintaining soil moisture during dry periods.  The organic matter also improves plant growth, regulates soil temperature fluctuations, and helps resist the erosive forces of rain and flooding.  “It’s all about soil building. I want to see what I can do to increase the OM of the floodplain lands and stay off the tractor when the soil is wet.”

During years of drought, Butterworks Farm has been short on feed for their herd of Jersey cows. They have relied upon increasing their land base to provide more summer forage and more hay in the winter.  Jack noted that maintaining good grazing practices during drought was crucial to the health of the entire agroecosystem.

Specifically, his rule is grazing down to only 3-4 inch height, instead of down to the ground or only 1 inch. He said, “If you want them to regrow quickly, don’t brutalize them.” That requires more land base, which not all farmers have.

Overall, Jack is transitioning is farm land to predominantly perennial forages. “Forage consumption has increased at least 40% for our transition to grassfed, which goes along with transitioning more land out of grain into permanent forage.”

“It’s all about soil building. I want to see what I can do to increase the OM of the floodplain lands and stay off the tractor when the soil is wet.” – Jack Lazor

Business Management Decisions 

Management decisions are informed by weighing a complex set of goals, challenges, constraints and opportunities. Butterworks Farm is transitioning away from grains because there are so many challenges, some of them directly or indirectly climate related. Jack says, “Though I love it, its not financially viable.” The farm is striving the make a transition into the hands of the next generation while reasserting a strong presence in the organic dairy market, though these trends are informed by, but not driven by climate change projections.

Constraints and Challenges

Jack recounted the history of the economic successes and trials of his business over the last 40 years, explaining that when the yogurt business took off and the business was flush with cash, they were able to not only purchase extra equipment and amendments, but also invest in the ecological sustainability and climate resilience of the farm. In this way, Jack linked the farm’s capacity to invest in new adaptive management strategies directly to the financial stability of the farm and market opportunities. Since 2008, the farm has experienced a decline in skim milk yogurt sales, which has dominated much of the farm’s strategic decision-making.

Making the investment into good soil and committing to regenerative agriculture takes a leap of faith, time and money, and Jack sees that some farmers are afraid of that. In Jack’s experience on the land, he sees the return on his investments into the minerals, soil amendments, cover crops and equipment show up in the health of the soil and the plants, and then in the health of his cows and quality of milk and cream.

Greenhouse Gas Mitigation Strategies and Potential

“My main takeaway from being on the land for 40 years is you think you’re being kind to the earth, but there’s always more you can do. Everyone needs to educate themselves and make changes.” – Jack Lazor

Jack emphasized the importance of developing a carbon consciousness. Agriculture has a lot of potential to offset the greenhouse gas emissions in multiple ways. We know that some carbon is captured by perennial, reduced tillage and other systems that increase organic matter, but exactly how much is captured is difficult to measure. Further research is needed on the carbon sequestration potential of grazing systems, and innovative manure and tillage methods. We should be proactive about this, even if the exact amounts of carbon sequestration or reduction in greenhouse gas emissions are unknown- every bit counts!

Adapting Farm Management to a Changing Climate – Butterworks Farm, Vermont

Filed Under: climate change adaptation, dought, water management by farmclim — Leave a comment
July 6, 2017

Butterworks Farm is one of Vermont’s oldest certified organic dairy farms, and has a strong reputation for growing some of the finest organic grains in the state. The farm building complex and surrounding fields are situated on gently sloping fields near the border of Canada. A herd of Jersey cows produces milk which is processed on site into yogurt, kefir and rich Jersey cream for direct and wholesale markets.

Butterworks Farm leases and owns additional parcels in the surrounding area, including some floodplain fields. The farm has grown a diversity of whole and milled grains for regional markets, and animal feed and is currently transitioning to a 100% grassfed operation with a bedded pack system. Alissa White visited Butterworks in early April 2017 to talk to Jack Lazor about how he manages his production with the impacts of climate change in mind.

Climate Vulnerabilities

Regional climate change projections predict agriculture in the northeastern US will experience a variety of direct weather impacts, and indirect impacts as a result of climate change. For Butterworks Farm in northern Vermont, the site-specific vulnerabilities of climate change encompass potentially both direct and indirect climate change impacts.

Direct Climate Change Impacts

  • Warmer temperatures overall,
  • Longer warmer growing seasons,
  • Precipitation increases,
  • Extreme precipitation events,
  • Increased flood damage and erosion,
  • Severe wind and storm hazards,
  • Elevated atmospheric CO2,
  • Increased potential for drought.

Indirect climate change impacts lead to increases in:

  • Weed competition and invasive species,
  • Populations of damaging insects,
  • Incidence of plant pathogens,
  • Livestock heat stress, and
  • Pressure from pathogens and parasites of livestock.

Management goals

Jack and his family balance many goals and challenges when making decisions about managing their farm. Climate concerns fall into both short and long-term decision making at Butterworks, but at the forefront of farm decision making for their family at this time are long-term financial solvency and near-term intergenerational transfer of ownership. Climate change considerations are important, but auxillary to day-to-day management and long-term planning.

How do we manage climate change and weather-related risks at the field scale?

Jack implements a number of practices on the field, specifically, managing for flooding and controlling soil erosion.  He has transitioned land which is particularly prone to flooding from grain production into permanent forage. “We’ve been farming this floodplain property for 20 years…Increased incidence of high water… could come any month of the year now… Then we only loose one cut out of three if there’s high water.” In previous years, the farm has used underseeding cover crops to limit erosion from high intensity rain events.

“We’ve been farming this floodplain property for 20 years… high water… could come any month of the year now…”

Jack attributes many benefits to crop rotations, including some that are directly associated with climate risks. His goal is to do less with tillage in all fields because he sees evidence of better soil quality and healthier plants without tillage.  By minimizing tillage and keeping roots in the ground, he maintains soil health with organic matter of 8-9%.

At the field scale, Jack is focused on increasing soil health to buffer the impacts of drought, flooding and extreme precipitation. Cover crops are planted to help hold soil from erosive forces, and land which is particularly flood prone is being transitioned into perennial forages to protect soil.

Building soil biological health and organic matter levels has multiple benefits for the farm.  Jack sees the soil health reflected in the plant growth, and in turn the health of his farm’s Jersey cows.  Increased organic matter limits the damage of extreme precipitation and holds moisture in times of drought.  In response to 2016 summer drought, Jack relied upon increasing his land base for forages and maintaining good rotational grazing practices.  In contrast, grain production has been challenging financially as it’s prone to disease during wet summers and storm events. Overall, the farm’s trajectory is towards perennial forages and away from grain production.

Raised Beds Raise Revenues at Golden Russet Farm

Filed Under: water management by farmclim — Leave a comment
March 24, 2017

Farming for over 30 years in Shoreham, Will and Judy Stevens have noticed climate changes at their organic farm – Golden Russet Farm.  From 1985 to 1995, Will recalls having a number of late frosts in May and that the first frost date typically occurred in early September. However, in the last 20 years, there’ve been only two years where the frost date has been as early as that, with the typical frost date extending to October.

Our growing season is longer and we have more frost-free days; we’ve had years where we’ve had no May frosts and more notably the fall has gotten longer.

In addition to the changes in frost dates, Golden Russet Farm has experienced both extreme storm events, as well as excessively wet growing seasons. 2011 was a persistently wet year, starting in spring and culminating with Tropical Storm Irene in August. Golden Russet Farm was in the red that year with a $34K loss. Much of the crop loss was due to soil saturation, not event flooding per se. The farm’s soils are a layer of loam on top of a layer of clay of varying thickness (2 to14 inches), which inhibits drainage from the root zone. Learning from 2011, Will says,

I’ll take a dry year over a wet year any day. It’s easier to manage dry conditions with irrigation than to be at the mercy of heavy rain events. We’ve noticed over the years that almost every rain event is a violent event. We used to get gentle rain. Now it’s thunderstorms and violent events. With 2.5 inches of rain in an hour, we needed to get rid of the surface water as we didn’t want standing water.

In 2012, working with their existing equipment (a three-bottom moldboard plow), the Stevens built up raised beds by alternating plow passes with 12 inch dead furrows. This roughly formed 36 inch wide ‘beds’. Going to this type of raised bed did add some complications. After soil smoothing and mulching, the Stevens ended up with a final bed width of 30 inches, but this width was too narrow for the transplanter and cultivators as they risked sliding off the beds.

After several years making adjustments, the Stevens invested in a three-point hitch bed shaper in 2015, which can be pulled with their tractor to shape 34-inch beds, moving soil up from the wheel track, so that only two passes need to be made with the press pans. The 34 inch top width of the beds matches up with the cultivator and transplanter. At the same time, drip irrigation tubing is put into place as the beds are made.

Will Stevens with his bed former purchased in 2015

The Stevens started by planting carrots, lettuce, beets, and spinach in some of the raised beds, and brassicas, broccoli and corn in others. In 2016, the Stevens had 12 raised beds of tomatoes, cucumbers, melons, peppers, flowers, and 11 raised beds of garlic across their 1.5 acre field.

With the bed shaper, there’s no need to till the topsoil. In fall 2016, the Stevens bought a chisel plow with four shanks for subsoiling as their soils have a plow pan, which needs to be broken up to make the soils more friable and further improve drainage. For 2017, their plan is to increase by a third the raised bed production area so that they’ll have two acres of raised beds in 2017, and then, they’ll expand to three acres by 2018. With raised beds, Golden Russet flower sales are up 50% from 2015 to 2016.

Raised beds keep me in farming and really reduce the risk of loss, especially mitigating the losses in a bad year. If we’d had raised beds that year (2011), we’d have had fewer crops with wet feet. We lost $4000 worth of carrots, and ended with none that we could sell.”

Soil temperature changes more quickly on raised beds with greater surface area exposed to air.

Raised Bed Equipment

2015 Purchases:

Raised bed shaper              $2,700

Chisel plough -4 shanks  $2,900

Drip tape layer                    $200

These equipment purchases of $5,800 represent only 17% of the cost of the Golden Russet losses in the year of Irene, 2011. Looked at another way, this $5,800 spent in 2015 was easily recouped the next year with the $7,000 annual increase in flower sales. While Golden Russet’s overall use and related costs of irrigation are up, it’s clear that the combination of irrigation to increase yields during dry periods and raised beds to prevent losses during wet periods will result in more stable revenues over the years.

A $5800 investment in equipment for raised beds was easily recouped in one year of increased revenues.

Golden Russet’s plan to move to raised beds arose from the worst case scenario of record wetness and Tropical Storm Irene in 2011, but as Stevens says, “Even in a dry year like 2016, there’s not really a downside.”

Suzy Hodgson visited Will and Judy’s farm in February 2017.

When Politics Go Low, Farmers Go High

Filed Under: climate change adaptation, water management by farmclim — Leave a comment
December 19, 2016

While political discourse hit new lows this past year, concern for climate change hit an eight year high in 2016.

US concern for climate change

US concern for climate change

Whatever headwinds affect legislation in the new year, a number of localities, states, and organizations are taking action.

Already, 165+ jurisdictions have signed or endorsed the Under2 MOU. Together, this group including Vermont and our neighboring states, New York, Massachusetts, New Hampshire, 7 other states and five Canadian provinces among others, represents more than 1.08 billion people and $25.7 trillion in GDP, equivalent to more than a third of the global economy.

This global compact among cities, states and provinces aims to limit the increase in global average temperature to below two degrees Celsius.  The Under 2 MOU calls for parties to aim to increase energy efficiency and develop renewable energy and to collaborate on climate change adaption and resilience efforts, scientific assessments, communication and public participation.

It is in this spirit of collaboration, communication, and adaption that UVM Extension Center for Sustainable Agriculture partnered with the USDA Northeast Climate Hub produced three videos showing Northeast farmers talking about their farms and how they’re experiencing climate change and are adapting with cropping strategies, water management and soil protection practices which mitigate climate impacts and help them farm successfully.

 

This past fall, 51.2 percent of the Northeast experienced moderate to exceptional drought, the largest extent since 2002 in the 17-year USDM record. Vermont was 3.5 F degrees warmer than its 20th century average, and this past year was the 2nd warmest year on record. period. This past fall was drier than on average, 2.38 inches less rain that the 20th century average.

In Vermont, Andy Jones, Manager, Intervale Community Farm in Burlington, VT explains how he uses irrigation to maintain soil moisture. Andy talks about his strategies in managing water, whether too much as in the summer of Tropical Storm Irene in 2011 or not enough as in this past summer 2016. Andy shares his thoughts on seeding rates and timing for the cover crops which protect the Intervale’s’s soils and shows the equipment he uses.

In New Hampshire, Pooh Sprague of Edgewater Farm, explains that even though his farm location is within feet of the Connecticut River, in dry periods, there’s no guarantee that he’ll be able to access enough water for this crops.   With increasingly erratic weather in the CT river valley, Poo has increased his use of hoop houses to protect his crops and extend the growing season.

Farms aren’t built in a single person’s lifetime.

Not far from the Connecticut River, Upinngill Farm sits on a hillside overlooking the river valley. The second generation of farmers in the family, Sorrell grew up farming with her father and now has her own two children growing up on the farm.  She says, “farms aren’t built in a single person’s life lifetime.”

Farmers throughout the northeast are experiencing the effects of extreme weather due to climate change and are managing their farms with the resources they can find.    It’s at this community level that the Intervale Community, Edgewater, and Upinngill farms are doing their bit to adapt to the new normal of climate change.

The summer it pays to be close to a water source for plentiful irrigation

Filed Under: climate change adaptation, water management by farmclim — Leave a comment
August 8, 2016

This week’s scattered showers are not enough to bring relief to the sustained dry summer we’re having in Vermont. Not suprisingly, the degree to which farmers and their crops are affected depends on their access to water and their irrigation systems.

In general, Champlain Valley farmers may be faring better than their neighbors in the Pioneer Valley, Masssachusetts.  While Vermont is experiencing abnormally dry weather, much of Massachusetts is facing severe drought conditions.

Moreover, Vermont farms that have invested in irrigation systems are reaping the benefits of this prolonged warm, sunny weather balanced by regular irrigation. With normal precipitation levels in Vermont at less than three quarters of their normal amounts, maintaining soil moisture is challenging but farms with healthy soils paired with an irrigation system are well positioned for this stretch of unusually dry weather.

Screen Shot 2016-08-08 at 12.10.26 PM

Percentage of Vermont experiencing abnormally dry weather from 2000 to 2016

In Burlington, Vermont, the Intervale Community Farm (ICF) started building its irrigation system 20 years ago.

We’re fortunate for being in the floodplain that we have abundant water supply with a main stem river and also some large high capacity wells in the floodplain – it has made us a much more resilient farm as we can contend with dry periods by using a mix of sprinkler and drip irrigation,” says Andy Jones, ICF’s farm manager.

Summers are hotter, the highs are higher, the existing soil moisture evaporates, and the plants transpire it more.  We use drip irrigation where we have plants that don’t want water on the leaves or that are spaced far apart so we can get some real weed control benefits and some water efficiency benefits by not watering the whole area. For winter squash, melons, cucumbers, sweet potatoes, peppers, we use sprinklers and for almost everything else, drip irrigation.

However, drip lines can be problematic for organic farms, which are using mechanical cultivation as their main weed control tool. As Andy describes, “it can be pretty challenging to move drip out of the way If you want to go through there every week with a tractor. Every time you’re moving the drip line and when you go back and weed, you have to move the drip line and then when you want to irrigate again, the irrigation line is not in the right place.”

Screen Shot 2016-08-08 at 12.22.36 PM

Andy describes that ICF’s sprinklers are spaced much farther apart so it’s easier to do routine weeding along with irrigating. There are also some cooling benefits from irrigation on a hot day with cool weather crops. And crops like greens and brassicas are hard to germinate in sandy soil without top water.

Andy points out the certain crops such as carrots, spinach, beets need water coming from above in order to germinate.  Drip lines don’t typically spread the water wide for germination of these crops to occur.

Covering 20 acres of their production field, ICF’s main sprinkler and drip irrigation system is a mix of old and new equipment.  Over the years, the farm’s investment in irrigation amounts to about $35,000.

I can’t imagine growing vegetables on sandy soil in a warm place like the Champlain Valley without irrigation – it’s absolutely critical to maintain crop quality and growth for a lot of our crops.”

Challenging conditions on Massachusetts Farms and Relief in Sight

Given this summer’s particularly dry conditions, irrigation can make the difference between a great harvest and poor harvest for many crops. Our neighbors in the Pioneer Valley, MA are taking a big hit. From crop loss to delaying second plantings, farmers without irrigation systems,  are holding out for rain, trying to catch up with laying irrigation lines, and even recruiting more workers and volunteers for hand watering.

In response to a UMass Extension survey, 80% of MA farm respondents are losing at least 30% of a specific crop. This data will determine whether USDA’s Farm Service Agency (FSA) in Massachusetts can seek federal disaster assistance.   In order to seek a disaster declaration and relief for Massachusetts’s farmers, the Farm Service Agency requires documentation of the extent of crop loss for each county.

While climate change in Northeast has meant a trend of warmer and wetter weather, this precipitation is occurring as more extreme episodic events and not necessarily when it’s needed, during the growing season. While five years ago we had record Lake levels and extreme flooding, for the past several summers, we’ve experience extended dry and hot periods in the Champlain Valley.   Farms like the Intervale Community Farm that have invested in irrigation systems and planned their system according to crop and soil type are well positioned to have a bumper year.

Irrigation has been essential as otherwise we would have lost so many crops as irrigation allows us not only to keep things growing and bulking up, but other crops we can’t even germinate without irrigation so it’s the difference between a crop and no crop.

Drought assistance can be found by contacting your County’s FSA office, USDA’s drought program assistance.  Information and technical assistance on developing a resilient farming strategy and building soil health in the face of climate change can be found at UVM Extension’s Center for Sustainable Strategy.

A Measure of Time

Filed Under: climate change adaptation by farmclim — Leave a comment
June 5, 2016

June 5, 2016. Temperature 70 degrees F and heavy rains of up to 3/4 inch.  Not outside the normal daily average of 52 to 74 degrees on this day and a daily rainfall  likely to be within the monthly averages. However, the current weather can obscure us from thinking clearly about climate change aka global warming.   Here’s a snapshot of what three farmers are saying about climate change and how they’re responding or not.

Our greenhouse has really beefed us up in terms of season extension.  When people’s gardens are failing, we have a really good crop of tomatoes and cucumbers.

By getting crops in and out of the ground faster, short rotations, we can manage our cash flow.

Global warming is not that simple – some summers are warmer, but some some summers are cooler.  We don’t have a new game plan. We haven’t changed our planting and harvesting schedules.

Upin

These anecdotes indicate that we don’t yet have a pattern to how farmers are responding to the Northeastern trend of warmer and wetter weather with more frequent heavy rain events.  The variability of weather and the significance of site, soils, and infrastructure adds a lot of variables to the assessment as well as noise to the anecdotes.   It may be only a matter of time until a clearer picture forms; as we talk to and share more experiences of Vermont farmers responding to longer-term weather trends, a pattern of adaption should start to emerge

As NOAA succinctly says, “the difference between weather and climate is a measure of time.”  It reminds me of what one farmer told me, “you can’t call yourself a real farmer until you’ve farmed at least 20 seasons.”   Years of practice, trial and error, we do know that many best practices go hand in hand with adaptation.

Adapting to climate change is playing the long game so in fact, our search for questions and adaptation answers has only really started.

The new normal – planning for wetter & warmer

Filed Under: climate change adaptation, water management by farmclim — Leave a comment
March 28, 2016

Normal temperatures at the end of March in Burlinton, VT are typically in the mid 40s like today.  Over Easter weekend, it was 16 degrees warmer than normal. With the warmest winter on record, what does this mean for Vermont farmers?

Revisiting Tamarack Hollow Farm, I checked in with co-owner Amanda Andrews. How is your new location working out?

Our new farm was great last season and held up during the heavy spring rains while our old farm was flooding. That said, heavy rains continue to be a worry, and so we are planning with erosion in mind.

To control erosion, we are planting low-growing cover crops between beds, moving towards a permanent raised bed system. We also installed drainage tile in one field with heavier soils to ensure it dries out quickly, even with heavy storms.

Spring is coming early this year – did we even have winter?   How has this affected your plans? Any thoughts on pests and diseases?

greens in hoophouse intervale

“With the warm winter, we are expecting heavier pest and disease pressure, so we are planning to use more row covers to control insects – and the diseases they spread.”

“Certain vegetables (tomatoes, cucumbers), we are only growing in tunnels. I am growing additional varieties of greens this season, especially looking for heat and disease tolerance as the three month forecast looks like a warm spring and summer.”
