In 2015, agricultural irrigation withdrawals accounted for about 42 percent of the total freshwater withdrawals in the United States (Dieter and others, 2018). Consistent and accurate designations of irrigated agricultural lands, irrigation system type, conveyance systems, and water source (groundwater or surface water) are essential for the determination of irrigation water use and ultimately the sound management of our nation’s water resources.

Several local, state, and federal agencies compile data (crops, irrigation, irrigation system type, etc.) that can be used to estimate irrigation withdrawals for agricultural. The format of these data varies from data tables, typically compiled at the county level, to spatial Geographic Information System (GIS) polygon layers of agricultural lands. These data sources are often incomplete, out of date, or inconsistently compiled. 

The USGS and the University of Wisconsin-Madison developed annual Landsat-based Irrigation Dataset (LANID), which consists of irrigation maps, derivative products, and manually collected ground reference data covering the conterminous US (CONUS) for the period of 1997–2017 (Xie and Lark, 2021a). These maps were developed using verified irrigated-lands GIS datasets (i.e. training data) coupled with remotely-sensed, 30-meter resolution Landsat-derived data. The current and future availability of verified field-level data is required to train and validate this and other models.

Season Eight Seed Speaks Preview - The Marketing Power of Seed

Video: Season Eight Seed Speaks Preview - The Marketing Power of Seed

Have you ever wondered how seed connects with the consumer? How the story of seed can be marketed or shared with a wider audience than the farmers who plant it and grow the crops it produces? On this season on Seed Speaks we’re taking a closer look at how the seed industry is connected to our daily lives.

The eighth season of Seed Speaks starts on April 12 and is entitled the Marketing Power of Seed.

Seed is the base of everything — any food you buy starts out as a seed. In this season of Seed Speaks we’ll tell you the story of seed and share the ways you can tell others about how seed is related to their lives.

Season eight will take a deep dive into the seed industry and how you can tell its story. We’ll talk with experts about how consumer preferences affect the seed industry, the world of cannabis breeding, how you can promote your seed business and many other topics.

Join every Wednesday at 12 Central Daylight Time on Seed World, Germination, European Seed and the Alberta Seed Guide’s Facebook pages, Seed World’s Linkedin page and Seed World Group’s YouTube page. We’ll be kicking off season eight on Wednesday, April 12, when Marc Zienkiewicz takes a closer look at the cannabis industry.
