# A methodological framework for assessing development solutions: application to wood fuel challenges in Nigeria

## TL;DR

This paper presents a new method to evaluate development solutions, focusing on wood fuel challenges in Nigeria and their impacts on multiple Sustainable Development Goals.

## Contribution

The study introduces a solutions-oriented methodology to assess co-benefits and trade-offs of development interventions.

## Key findings

- Solutions increasing wood fuel availability address environmental and social issues but not health challenges.
- Alternative fuels/technologies face barriers like affordability, market access, and cultural acceptance.
- The proposed iterative process emphasizes context-specific planning and multi-sector collaboration.

## Abstract

Development interventions often yield co-benefits and trade-offs across multiple Sustainable Development Goals (SDGs). However, current approaches typically assess progress towards specific SDG targets, such as increasing access to clean energy or improving health outcomes, rather than evaluating the co-benefits and trade-offs of the solutions used to achieve these targets. This study introduces a solutions-oriented methodology to assess the impacts of development solutions, applied to the case of wood fuel cooking-related challenges in Nigeria. Using a rapid evidence assessment and stakeholder workshop, we identify co-benefits, trade-offs, and barriers associated with 13 wood fuel-related solutions, classified into three types: enhancing fuelwood availability, adopting alternative technologies, and implementing external interventions. We find solutions that increase wood fuel availability can address environmental and social issues, but not health challenges, while alternative fuels/technologies face affordability, market, and cultural acceptance barriers. We highlight data limitations and propose an iterative process to comprehensively evaluate solutions’ impacts. This process facilitates context-specific, cross-sectoral planning but underscores that no universal solution exists. Successful interventions require multi-sector collaboration, public education, and strengthened governance to balance competing priorities and ensure equitable outcomes. By advancing solutions-based approaches, this study contributes to integrating SDG interactions into practical, evidence-informed policy and programming.
