Wastewater can be an asset, but in most developing countries treatment systems are either lacking or inefficient. As a result, wastewater used for irrigation tends to be of very low quality, especially near urban centres. Crops grown using this method carry a high health risk for consumers, especially in the case of fruit and vegetables that are eaten without being cooked.

Making the critical link between agriculture, health and sanitation, the authors take a practical approach to this issue, exploring in concrete terms how wastewater can be used in farming, and how the health risks can be kept to a minimum. By examining case studies such as wastewater-irrigated lettuce in Ghana, the book presents effective low-cost options for using wastewater safely, including on-farm and off-farm measures. Chapters also deal with related issues such as risk assessment, cost-effectiveness, livelihood impact and wastewater governance.
