Water Sanitation and Hygiene Sector Nigeria: Theory of Change

The document outlines the Theory of Change (ToC) for the Water, Sanitation, and Hygiene (WASH) sector in Nigeria, developed by the Federal Ministry of Water Resources with support from various partners. It presents a structured approach to achieving significant societal impacts through improved WASH services, contributing to enhanced health, education, and economic outcomes. Goals: The ToC aims to end open defecation by 2025 and achieve universal access to safe sanitation as part of the ‘Clean Nigeria: Use the Toilet’ campaign. It also aligns with the Sustainable Development Goal 6 (SDG 6) targets for 2030.

Key Principles: The ToC is founded on principles such as equity, evidence-based decision-making, and sustainability. It emphasizes large-scale interventions, user/polluter pays concept, and a decentralized approach to service delivery.

Building Blocks: Critical to the ToC’s success are political will, capacity building, enabling environment, financing, partnerships, and robust monitoring systems.

Outcomes and Outputs: The document details the desired outcomes like equitable access to WASH services, an enabling environment for sustainability, and resilience to risks. It specifies outputs such as functional water services, safe sanitation facilities, and established social norms on WASH behavior.

The ToC serves as a comprehensive framework for all stakeholders to work towards a common vision and strategy for the WASH sector in Nigeria.
