Current Environmental Issue Study Guide 2020
Water Resources Management: Local Control and Local Solutions
The Current Environmental Issue is always selected by the host of the North American competition. in 2020 Nebraska will be the host.
Nebraska is fortunate to sit atop the Ogallala aquifer, one of the largest unconfined aquifers in the world. This natural resource provides drinking water for most of the state and has enabled Nebraska to lead the country as the #1 irrigated state, helping to sustain agriculture as the states leading industry. Managing and protecting this resource is the responsibility of Nebraska’s unique local Natural Resources Districts (NRDs). While NRDs have maintained groundwater levels near pre-development levels, competing uses and variable supplies have placed additional management requirements on locally elected policy makers.
