The document argues that while total eradication of invasive carp in the Mississippi River Basin is unlikely, creating sustained market demand—particularly in the growing US pet food sector—can suppress carp density, reduce the risk of spread into the Great Lakes, and improve biodiversity. It highlights the need for a robust supply chain that supports commercial fishers through innovative business models like co-ops and 'hub and spoke' processing. The report also outlines a plan to scale these market-based approaches to other invasive species through a new framework for assessing economic and ecological potential.

Agricultural runoff of nitrogen and phosphorus is a primary driver of water contamination and eutrophication in the U.S., particularly affecting the Great Lakes and the Gulf of Mexico. While the Clean Water Act does not regulate water leaving farmers' fields, various state-level initiatives and federal programs, such as the USDA's Regional Conservation Partnership Program (RCPP), promote voluntary best management practices to reduce nutrient loading. Climate change is expected to worsen these issues by increasing the frequency of extreme weather events that trigger higher runoff.

The document argues that the Renewable Fuel Standard (RFS) has failed to meet its goals of producing clean renewable fuels and protecting consumers, instead primarily incentivizing corn ethanol. It highlights negative impacts including increased greenhouse gas emissions from land conversion, water pollution in the Mississippi River Basin and Gulf of Mexico, and increased food prices and land displacement in developing countries and the United States.

A World Resources Institute (WRI) analysis finds that the U.S. Department of Agriculture (USDA) could achieve seven to 12 times more environmental benefits for the same budget by combining geographic and benefit-cost targeting for water quality improvements. Currently, only about $335 million of the $5 billion annual federal conservation budget is spent on controlling soil erosion and fertilizer runoff. The analysis shows that nitrogen pollution reductions could increase from 91 million pounds annually at $3.65 per pound to 1.1 billion pounds at $0.30 per pound through optimized targeting. However, technical gaps in identifying cost-effective acres, the voluntary nature of programs, and political resistance to shifting funds act as barriers. WRI recommends quantifying environmental benefits, incorporating benefit-cost principles into planning tools, conducting pilot projects, and revisiting state funding allocation formulas.

The study concludes that nutrient trading in the MRB is economically feasible, as wastewater utilities could significantly reduce costs by purchasing credits from the agricultural sector. Using case studies of two utilities and six agricultural watersheds, the report finds that nitrogen (N) supply is sufficient to meet demand, while phosphorus (P) supply is more limited. It highlights that some conservation practices are profitable for farmers even without trading due to fertilizer savings and yield increases. However, the report notes that the lack of a strong policy driver, potential local water quality standards, and regulatory capacity are significant barriers to implementation.

The report analyzes EGS programs in the UK, Australia, France, Switzerland, the US, and Canada, emphasizing the shift from regulatory approaches to economic incentives. It highlights the importance of multifunctionality, geographic targeting, and public accountability. For Manitoba, it recommends a consolidated, watershed-based approach incorporating performance measurement and adaptive management.

The report outlines the foundational research for a decision support system (DSS) to facilitate ecological infrastructure investments in the Red River Basin. It identifies critical data gaps, particularly in high-resolution elevation data for Canada, and evaluates existing hydrological and ecosystem models. The project emphasizes the need for harmonized transboundary data and a common vision for basin management to address chronic flooding and the eutrophication of Lake Winnipeg.

The document examines strategies to reduce nitrogen runoff from agricultural land in the Mississippi River Basin to address the 'Dead Zone' in the Gulf of Mexico, identifying market-based mechanisms as the most efficient solution.
