The document outlines a framework for evaluating the economic impact of transmission infrastructure, focusing on three primary benefit categories: congestion relief, resource adequacy, and public policy savings. It describes the specific calculations used for these benefits, the financial models applied to different ownership structures (investor-owned, public power, and merchant developers), and compares the results against original project projections for three specific case studies. The authors acknowledge several conservatisms in their approach, including the exclusion of certain benefit categories and the use of isolated line capacity estimates rather than complex power flow simulations.

The report highlights Lake Winnipeg's extreme vulnerability to upstream pressures due to its very low volume relative to its massive drainage basin. It argues that managing the lake in isolation is insufficient and recommends a transboundary, basin-wide framework that treats land as 'ecological infrastructure.' By implementing distributed storage and wetland restoration, the region can mitigate floods, capture nutrients, and buffer against climate change while supporting hydroelectric generation. The document draws on case studies from the Columbia River and Murray-Darling basins to illustrate how integrated water resources management (IWRM) and ecosystem services can balance competing economic and environmental needs.

The paper examines the role of economic valuation in Watershed Development (WSD) in India, using a benefit-cost analysis (BCA) of a project in Maharashtra to demonstrate positive returns. It identifies significant gaps in data consistency and the failure to value non-market co-benefits, while providing recommendations for integrating economic valuation into climate change adaptation (CCA) strategies.

The paper finds that securing community forest tenure in Brazil and Guatemala is a low-cost, high-benefit investment where economic benefits outweigh the costs, making it a cost-effective measure for climate-change mitigation compared to other options.

The report provides an economic analysis of securing indigenous land rights in the Amazon basin of Bolivia, Brazil, and Colombia. Using matching analysis, it finds that tenure-secure indigenous forestlands have significantly lower deforestation rates than similar non-secure lands. A benefit-cost analysis indicates that the investment is low-cost and high-benefit, with total ecosystem service benefits estimated between $679 and $1,530 billion over 20 years, while costs represent less than 1 percent of these benefits. The report argues that securing indigenous tenure is a more cost-effective carbon mitigation measure than fossil carbon capture and storage. It recommends that governments reform laws to strengthen community land rights and integrate tenure security into their Nationally Determined Contributions (NDCs).
