Two Seminars Today:

Multi-State Financial Data for Use with the Agricultural Conservation Planning Framework

Presenter: Emma Bravard, GIS certificate candidate, natural resource ecology and management
Advisor: John Tyndall, associate professor, natural resource ecology and management


The Agricultural Conservation Planning Framework (ACPF) is a GIS-based conservation planning tool that uses high-resolution elevation and water flow data to spatially identify critical source areas for nitrogen loss within agricultural watersheds. The ACPF allows users to explore different best management practice (BMP) opportunities and analyze potential nutrient loss reduction outcomes.

Bravard has developed a multi-state financial data set and a field-scale nitrogen reduction tool to calculate total long-term cost of various conservation scenarios. The tool quantifies the nitrogen requirements for each field and evaluates the proportion of nitrogen likely to be lost via leaching. Land-use opportunity costs of BMPs that remove land from production are spatially determined according to state-relevant weighted-average crop productivity indices and land rent relationships.

The combination of these data will assist water quality stakeholders to determine placement of conservation practices to yield the most effective and lowest cost Nitrate-N reduction at a watershed scale.

Using Public Policy and Erosion Modeling to Protect Indigenous Water Quality

Presenter: Monika Moore, GIS certificate candidate, political science


Poor water quality and a lack of adequate infrastructure on Native American reservations has caused harm to the environment and human health. This presentation outlines the powers that Native American nations have in protecting their water under section 303 of the Clean Water Act and uses Minnesota as an example of policies preventing soil loss and erosion in developing areas.

These powers can be used to increase water quality by regulating development and instituting management practices to decrease non-point source pollution. Using 3DEM data with the SATEEC system and RUSLE to locate watersheds vulnerable to erosion due to overland flow and related pollution on reservations in Idaho and Utah, the RUSLE is used to calculate annual soil loss per year and contrast management with indigenous cultural practices to prescribe effective soil management practices for each site.

It is expected that where there is positive population growth, indicating development, or oil and gas wells there will be higher erosion.

This spring 2021 series will be using an online format. Hosted by the Department of Community and Regional Planning, the GIS Seminar Series is open to the public. If you are interested in attending a presentation, please send an email to Monica Haddad ( at least one day in advance, and she will send you a link with Webex information to attend.
