A pilot project in Minnesota for immigrant families shows how small-scale sustainable farming with poultry and perennial crops can provide extra income with little investment of time.

Researchers in Minnesota are developing perennial food crops that could revolutionize American agriculture.

Where the Colorado River approaches the Sea of Cortez, conservationists re-plant forests and promote wildlife habitat to revive the Delta after decades of neglect and desertification.

To protect one of Arizona’s last perennially flowing rivers, smart stewardship minimizes irrigation and clears invasive plants.

Where the Colorado River approaches the Sea of Cortez, a new agreement between the U.S. and Mexico shares the river’s water during times of drought and surplus and dedicates water to the environment, restoring flows and habitat along the river and at the Delta. Conservationists are working hard to re-plant forests and promote wildlife habitat to revive the Delta after years of neglect and desertification. On the leading edge of agricultural technology, young farmers are using data to minimize costs, improve yield and increase profits; a fourth-generation farmer in Illinois shows how it’s done.

To protect one of Arizona’s last perennially flowing rivers, conservationists practice smart stewardship to minimize irrigation and clear invasive plants. Taking advantage of open areas in crowded cities, urban farmers are growing healthy foods and making profits. Studying iconic sandstone arches in the Southwest, researchers learn how these formations vibrate and gather data to help understand their architectural health.

From recent episodes of THIS AMERICAN LAND, these brief summaries of stories highlight major repair and maintenance issues affecting America’s national parks.

With new water rights and a major irrigation project under construction, Arizona’s Gila River Indian Community is reviving an agricultural heritage that sustained them for centuries before white settlers arrived.

With new water rights and a major irrigation project under construction, the Gila River Indian Community in Arizona is gearing up for a revival of an agricultural heritage that sustained them for centuries before white settlers arrived. Public-private partnerships in national parks are saving taxpayers money while supporting critical services, maintenance and repairs. With individual fishing quotas for red snapper, charter boat captains on the Gulf Coast adopt new sustainable practices that provide them with more income and safety.

A farmer in southwestern Iowa has a mission to develop his farm as an example to others, using no-till seeding, multi-crop and pasture rotation, minimal fertilizing, and runoff filtering to keep the nutrients in his soil and prevent runoff. The backlog of deferred maintenance in national parks is a growing problem that needs Congress to act: we see the need for urgent maintenance and repairs at the Grand Canyon, the National Mall, and the Martin Luther King, Jr. Historic Site in Atlanta.
