Introduction

In Study Session 1 you read about urbanisation and how its trends are challenging WASH service provision. You also saw how urbanisation can have a negative impact on the environment. In this study session you will consider environmental pollution issues related to WASH and the implications for the health of communities.

Later in the module, you will learn how these issues might be tackled through community engagement (Study Session 6), influencing behaviour (Study Session 9) and promoting improved hygiene and sanitation (Study Session 10).
