On-farm practices for the safe use of wastewater in urban and peri-urban horticulture

This training handbook is a field guide for training urban and peri-urban vegetable farmers in safe practices for irrigating their vegetables with wastewater. It is designed to provide complete information, knowledge and skills for the successful safer production of vegetables in urban and peri-urban farming systems. Once you have gained this knowledge, we urge you to share the knowledge and skills you have gained with other farmers in your neighbourhood, so that they too can produce cleaner vegetables that are safer to eat. The handbook includes two chapters and several exercises to guide you.

The handbook covers five major topics:

  • We explain how irrigation water might be polluted with wastewater from the town or city and how using such water for production of fresh vegetables poses health risks to you, the farmer, and to people who eat the vegetables you produce.
  • We describe the various methods that you can use on your farm to reduce the health risks associated with using wastewater for irrigation.
  • We show how you can check the performance and results of these safe practices.
  • We help you to train other farmers in your neighbourhood.
  • We explain ways to communicate the knowledge and skills acquired from the training to larger audiences, like through radio and field days.
