A Transdisciplinary Approach to Reducing Global Plastic Pollution

In a commentary published by Frontiers in Marine Science, Duke experts outline evidence underscoring the urgency of the plastic policy crisis and recommend novel research-based interventions. The interdisciplinary group of authors are part of Duke's Plastic Pollution Working Group.

Can Time-of-Use Tariffs Increase the Financial Viability of Mini-Grids?

Declining solar and battery costs and increased operational efficiency have helped expand community-scale mini-grids, especially in sub-Saharan Africa and South Asia, where they now meet the power needs of over 47 million people. However, mini-grid system economics must continue to improve to be a reliable power solution for the nearly 800 million people still lacking access. Time-of-use (ToU) tariffs could represent one piece of the solution. This policy brief develops a model to estimate the effects of a ToU tariff using data from Energicity, a solar mini-grid operator in Sierra Leone.

Spatial Patterns in Water Quality Portal Data: Identifying and Addressing Gaps in Water Quality Monitoring and Reporting

Data from the Water Quality Portal were analyzed to determine spatial patterns in monitoring coverage at the subwatershed scale. These patterns were integrated with population, race, ethnicity, and income data to determine what communities may be underserved by monitoring. Trends varied by state and EPA region but were more strongly correlated with population density than with race, ethnicity, and income. Findings were compiled into a dashboard and recommendations for policy and practice were developed for increasing the comprehensiveness and accessibility of water quality monitoring data.

Automated Extraction of Energy Systems Information from Remotely Sensed Data: A Review and Analysis

High-quality energy systems information is crucial for energy systems research, modeling, and decision-making. Unfortunately, actionable information about energy systems is often of limited availability, incomplete, or only accessible for a substantial fee or through a non-disclosure agreement. This systematic review explores remote sensing and machine learning for energy data extraction.

Developing a State-Level Natural and Working Lands Climate Action Plan

Natural and working lands—forests, wetlands, coastal, and agricultural lands—provide many benefits, including supporting key economic sectors, enhancing community resilience to hazards such as fires and floods, and contributing to climate mitigation by storing large amounts of carbon. This guide is aimed at states interested in developing plans for conserving, managing, and restoring these lands to preserve and enhance their benefits. The guide uses examples from North Carolina’s recently completed Natural and Working Lands Action Plan to walk through the planning process, helpful resources, and the tracking of plan implementation.

Guidebook for the Engaged University

The next phase of academic reforms must build toward the broad institutionalization of engaged scholarship, as demanded by students and the communities that surround and support universities. The Guidebook for the Engaged University gives the academy both a vision and a roadmap to a more impactful future, in which universities, including their scholars and staff, catalyze solutions for the world’s most pressing challenges.

Climate Finance for Just Transitions

This paper investigates challenges in the international climate finance landscape through three issue areas: (1) aligning national climate strategies and international finance, (2) finding avenues for positive climate finance outcomes in an era of growing rivalry between Chinese and Group of Seven—particularly US—public financiers, and (3) reforming major climate finance practices and institutions to more effectively cater to the needs of LMIC stakeholders.

Developing Key Performance Indicators for Climate Change Adaptation and Resilience Planning

This document from the Resilience Roadmap project recommends a common approach to developing key performance indicators (KPIs) for climate change adaptation and resilience planning, drawing upon current science and tools referenced throughout. The work is particularly aimed to support climate adaptation and resilience planning by US federal agencies and thus presents principally US national-level data and online resources. The approach is broadly applicable across agencies, sectors, and systems and can also be applied by state or local planners and adaptation/resilience practitioners.

Proximity to Small-Scale Inland and Coastal Fisheries Is Associated with Improved Income and Food Security

Poverty and food insecurity persist in sub-Saharan Africa. The authors conducted a secondary analysis of nationally representative data from Malawi, Tanzania, and Uganda to investigate how both proximity to and engagement with small-scale fisheries are associated with household poverty and food insecurity. Results suggest that households engaged in small-scale fisheries were less likely to be poor than households engaged only in agriculture. Households living in proximity to small-scale fisheries were more likely to achieve adequate food security and were less likely to be income poor, compared to the most distant households.

The Role of Taxes and Subsidies in the Clean Cooking Transition: A Review of Relevant Theoretical and Empirical Insights

Cost barriers are among the most significant challenges impeding progress toward use of clean cooking energy in low- and middle-income countries (LMICs). This brief discusses the role of subsidy and tax policies—levied on both the supply and demand side—in affecting progress toward universal access to clean cooking in LMICs. Also, combating a common myth among those opposing subsidies for clean cooking, the brief demonstrates that a “fear of spoiling the market” with such incentives finds little empirical support in the literature. Finally, the brief offers recommendations to policy makers.
