Growing Returns

Mississippi River flooding and Hurricane Barry could have inundated New Orleans. Here are four actions we need to take before that happens again.

The Bonnet Carré Spillway will finally close this week after two separate openings totaling an unprecedented 120 days. The spillway was built to protect New Orleans and surrounding parishes from Mississippi River flooding as part of the Mississippi River and Tributaries system designed after the Great Flood of 1927.

This comes on the heels of another first when, earlier this month, Hurricane Barry was the first tropical storm to make landfall while the Mississippi River was at flood stage. This one-two punch — tropical storm combined with high river — was previously only a nightmare scenario with the potential to send storm surge upriver, overtopping levees, inundating the city and surrounding region, and shutting down globally significant commerce.

Mercifully, that scenario did not occur—Barry shifted westward, river levels never reached projected heights and rainfall diminished. However, the river remains dangerously high into the thick of hurricane season. During Hurricane Katrina, storm surge in the river increased the water level by 13 feet, but the river was so low that it wasn’t a threat. The combination hurricane-river flood scenario could play out again – and next time we may not be so lucky.

Louisiana floods in three ways: 1.) From water flowing down the Mississippi and other rivers; 2.) From storm surge and rising seas from the Gulf of Mexico; 3.) From rainfall, now increasing in intensity and overwhelming existing drainage systems. With Barry, for the first time ever, we faced all three threats at once, and climate change will only compound them.

Going forward, we must learn to live with water. On the Mississippi River specifically, the current management system no longer meets the needs of the future. Here are four strategies to help us get there:   Read More »

This Midwest hog farmer wants to create a “butterfly effect” to bring back the monarch

Eastern monarch butterfly populations rebounded last year, largely thanks to favorable weather conditions during the butterflies’ 3,000-mile migration. To help make those increases permanent and reduce chances of an endangered species listing, we need to plant 1.5 million more acres of milkweed, native grasses and wildflower habitat on farms and ranches.

Farmers like Tim Richter, who manages a grain and hog operation in Iowa and Missouri, are stepping up provide monarchs with vital breeding and nectaring habitat.

I sat down with him to discuss what inspired him to restore monarch habitat, and to ask him what he wants other farmers to know about pollinator conservation. Read More »

The Groundwater Game: A new hands-on way to learn about groundwater management

One evening, at a community center in the Sacramento Valley, a teacher, a civil engineer, a tomato farmer and a local foundation board member found themselves standing above a table, feverishly competing to scoop the most glass beads from a large, communal bowl.

But there was a catch. Read More »

A new guide for farmers to boost profits through conservation

As the struggling U.S. farm economy continues to make the news, agricultural organizations, government agencies and conservation groups are rightly focusing their attention on the affordability of conservation adoption.

A 2018 report from EDF and agricultural accounting firm K·Coe Isom, Farm Finance and Conservation, found that farmers who adopt conservation practices such as no-till, nutrient optimization, cover crops and diverse rotations improved their profitability and were more resilient.

Despite these benefits, the costs of transitioning to conservation management practices can be a barrier to adoption. In addition, any change carries some risk, and farmers are likely to be reluctant to take on additional risk in the current economic climate.

For these reasons, it is more important than ever to provide farmers with practical guidance on how to minimize the costs and risks of conservation adoption. Fortunately, a new technical bulletin from the Sustainable Agriculture Research and Education (SARE) program at the U.S. Department of Agriculture does just that.

Cover Crop Economics: Opportunities to Improve Your Bottom Line in Row Crops [PDF] describes seven different management scenarios in which farmers can speed their transition to cover crops and achieve profitability more quickly — in some cases within the first year of adoption. Read More »

What’s next for California’s Central Valley? Even with water cutbacks, the region can still thrive. Here’s how.

California’s Central Valley has reached a fork in the road.

By January 2020, areas where groundwater demand far outstrips supply must submit plans to bring their groundwater basins back into balance within 20 years. These plans are required by the Sustainable Groundwater Management Act, or SGMA, which was signed into law in 2014 during the state’s latest multiyear drought.

SGMA inevitably means less water for irrigating farms. Worst-case estimates forecast as much as 780,000 acres of farmland — out of more than 5 million acres of total irrigated land — will have to be taken out of production. How local decision makers and community members navigate this transition to sustainable groundwater management will significantly shape the future of the region, known as the country’s fruit and nut capital.

On one path, the valley could become a patchwork of dusty barren fields, serving a huge blow to the agriculture sector and rural communities and further impairing already poor air quality. Active farms could become surrounded by fields of invasive weeds and pests, threatening productivity.

On another path, the valley could transform into a pioneering agricultural region that not only puts food on our nation’s plates but also supports thriving wildlife habitat, outdoor recreation, soil health, groundwater recharge and flood control.

EDF is working to help communities achieve this second vision through our Central Valley Resilience Initiative, which features three key strategies: conversion of farmland into wildlife corridors, water trading and community engagement. Of course, all three strategies will require additional funding at the state, regional and local levels. Read More »

Attention Congress: Investing in nature can help our flood-ravaged nation

Call 2019 the year of the flood.

This spring large swaths of the nation experienced moderate to severe flooding – and the rain isn’t stopping. In California, record rainfall and snow persisted into May. In Louisiana, for the first time ever, the Army Corps of Engineers just released water through its Bonne-Carré spillway twice in a single year to avoid flooding. And hurricane season is just beginning.

The deluge of floods is hardly a coincidence.

Land-use changes and extreme weather driven by climate change are delivering a one-two punch that heightens flood risk. We’ve increased impervious surfaces – think asphalt and concrete – and at the same time we’ve removed wetlands, prairies and forests, which can absorb water and slow runoff. We’ve also built hard infrastructure such as bridges, urban and agriculture drainage networks, and even, ironically, flood “protection” projects that often alter watersheds, floodplains and stream hydrology and increase the severity of floods.

So how do we better protect critical infrastructure and communities in the face of increased flooding? Read More »

Hurricane season is here. What past storms can tell us about reducing risk.

With the start of another Atlantic hurricane season, coastal residents from Texas to New York should hope for the best and prepare for the worst. While the current prediction is for a close-to-normal 2019, prior years have demonstrated that it only takes one storm to bring widespread devastation.

In 2018, Hurricane Michael became the first Category 5 storm to hit the continental U.S. since Hurricane Andrew in 1992. Communities are still recovering from the unprecedented 2017 Atlantic Hurricane season, which caused $282 billion in damages, including $92.2 billion in Puerto Rico and the U.S. Virgin Islands from Maria and $128.8 billion from Harvey in Texas.

Through this devastation, we have learned several important lessons about how to better prepare for and react to storms to reduce damages and hasten recovery.    Read More »

The monarch ESA listing is delayed 18 months. Here’s what you need to know.

The U.S. Fish and Wildlife Service delayed its decision about whether to list the monarch butterfly as endangered or threatened until December 2020 — 18 months later than the original deadline of June 2019.

Because the original deadline resulted from a litigation settlement, this extension had to be approved by federal courts and the other parties to the litigation. While certainty about a regulatory decision of this scope is always beneficial, this mutually agreed upon delay creates an opportunity that shouldn’t be missed.

Here’s what farmers, ranchers and their partners need to know about how the delay will impact monarch conservation efforts. Read More »

Three ways nature can help rebuild and protect communities following Cyclone Fani

My upbringing drew me to work in coastal hazards. Though I work on coastal resilience in Louisiana, I spent much time throughout my childhood and adult life in Odisha, a state with a 300-mile coastline along the Bay of Bengal. Odisha is part of the bay’s infamous cyclonic zone that stretches across the Bangladeshi lowlands, and its coastline has been subjected to devastating storms and floods intensified by the effects of global warming and sea level rise.

Gov. Newsom can be a climate leader by focusing on resilience. Here’s how.

In pulling the plug on the twin Delta tunnels and scaling back California’s high-speed rail line, Gov. Newsom broke from his predecessor, who fiercely defended the projects as part of his climate agenda.

But that doesn’t mean Newsom can’t build on Jerry Brown’s strong climate legacy. He can, all while charting a different legacy for himself.

While it may be unfair to reduce Brown’s climate achievements to a few bullet points, two themes often appeared in his initiatives: prioritizing policies to slash greenhouse gas emissions, and capitalizing on the state’s ability to impose mandates.
