irrigation

Approximately one-half of 1% of the planet’s water is drinkable, and we use that water for much more than drinking – showering, brushing our teeth, watering our grass, etc. Consumer usage, however, pales in comparison to the amount of water needed to irrigate our crops.

The Ogallala Aquifer is one of the world’s largest fresh groundwater resources. It underlies 175,000 square miles in eight states. Starting as hundreds of feet of silt, clay, and gravel eroded from the Rocky Mountains and laid down by streams millions of years ago, rainfall during this time produced an underground lake the size of Lake Huron.

Each day, USDA employees wake up ready to serve the industry we love – agriculture. As we help farmers, ranchers and foresters move agriculture forward, we remember and recognize the achievements of those who brought us to where we are today. You might think of George Washington Carver or Eli Whitney, but it was also the unknown others – the “Wonder Women” of agriculture – that had a tremendous impact on the world around us.

Conservation is giving Vietnam War veteran Gilbert Harrison a peace offering of healing, helping to balance the stresses of war. For Harrison, conserving the natural resources on his farm is an important outdoor activity. And who better to care for the land than the veterans who fought to protect it?

Harrison has worked with the Natural Resources Conservation Service (NRCS) since 2012, when he received funding and technical assistance through the Environmental Quality Incentives Program (EQIP) to help him install an improved irrigation system to help develop alfalfa production on his land.

Nobody wants fish to get stuck in irrigation pipes. Not the public; not the farmers; especially not the fish. But with more than 70,000 irrigation diversions tapping into Oregon’s rivers and streams, the concern is real.

Irrigation diversions channel stream water through a series of narrowing pipes, eventually reaching fields through irrigation devices. Until recently, there’s not been an adequate selection of screens to prevent high-gravity and sediment diversions from getting clogged. Diversions on wooded hills required daily maintenance during certain times of the year.

When Amanda Barker arrived in Worcester, Massachusetts, in 2009 to start graduate school at Clark University she knew that she wanted to grow food and build community. “My hope was to figure out a way to connect people with food, get people talking to each other,” said Barker.

Seven years later, she is one of the nation’s urban agriculture pioneers who raises crops on tiny patches of land wedged between city buildings, used car lots, highways and railroad tracks, and even on rooftops.

All this month we will be taking a look at what a changing climate means to Agriculture. The ten regional USDA Climate Hubs were established to synthesize and translate climate science and research into easily understood products and tools that land managers can use to make climate-informed decisions. The Hubs work at the regional level with an extensive network of trusted USDA agency partners, technical service providers, University collaborators, and private sector advisers to ensure they have the information they need to respond to producers that are dealing with the effects of a variable climate. USDA's Climate Hubs are part of our broad commitment to developing the next generation of climate solutions, so that our agricultural leaders have the modern technologies and tools they need to adapt and succeed in the face of a changing climate.

Despite hopes for a drenching from El Niño, California farmers are facing another drought year in 2016.  Even after four years of the worst drought on record, California farm output was a record $54 billion in 2015, accounting for more than half of the nation’s fresh produce. Groundwater has helped compensate for California’s lack of rainfall, but groundwater overdraft cannot be continued indefinitely.

California farmers have responded to the drought by fallowing land; switching to crops that yield higher value per unit of water; and switching irrigation technologies.  Almost all California cropland is irrigated, so continued improvements in irrigation efficiency are key to weathering this and future droughts.

Spaniards built the Acequia de Las Joyas approximately 300 years ago. The acequia, a community irrigation watercourse or ditch, was the principal method of providing water to the farmers for their crop and rangelands in northern New Mexico. The parciantes (also known as acequia members) worked together to maintain the acequia and each member in return received a portion of the water.

Three centuries later, the practice is still key to making the land bloom. But, time and the elements have taken their toll on acequia and repair costs have escalated to the point that members can no longer shoulder the burden of maintaining the critical community resource alone.

“The Conservation Innovation Grant program has an impressive track record of fostering innovative conservation tools and strategies,” said Agriculture Secretary Tom Vilsack as he announced $20 million in new funding for the program. “Successes in the program can translate into new opportunities for historically underserved landowners, help resolve pressing water conservation challenges and leverage new investments in conservation partnerships with farmers, ranchers and other stakeholders.”

Conservation Innovation Grants (CIG) fosters innovation in conservation tools and strategies to improve things like on-farm energy and fertilizer use as well as market-based strategies to improve water quality or mitigate climate change. Last year CIG began supporting the burgeoning field of conservation finance and impact investing to attract more private dollars to science-based solutions to benefit both producers and the environment.

In the Ogallala Aquifer region, each drop of water counts. A group of forward-thinking farmers in Texas are finding innovative ways to irrigate their crops to use water more efficiently.

These farmers are working with the North Plains Groundwater Conservation District in the panhandle to study use of water from the aquifer. The Ogallala is the nation’s largest aquifer and is being depreciated by water withdrawals at an unsustainable rate.
