Flyway Flooding Impacts with Dr. Amitava Chatterjee

“Shallow water habitat management influences soil CO2 efflux from agricultural fields in the Lower Mississippi River Basin (LMRB), USA” with Amitava Chatterjee.

The Lower Mississippi River Basin (LMRB) serves as a critical stopover habitat for migratory birds traveling between Canada and Central and South America, presenting both challenges and opportunities for habitat conservation. To support these birds, farmers in the region flood agricultural fields in the winter, creating temporary wetlands that provide habitat and essential food sources. This practice has increased bird stopovers but raises concerns about soil health, as flooding can alter soil properties. In this episode, Dr. Amitava Chatterjee shares his insights on research related to the effects of flooding on soil properties in agricultural lands in the LMRB and how it contributes to maintaining sustainable stopover habitats for migratory birds.

Tune in to learn:

· What migratory bird stopovers are

· How flooding of agricultural lands helps migratory birds

· How flooding of agricultural land affects soil health

· How flooding affects soil microbial activity

· What are the long-term impacts of agricultural land flooding
