Wastewater use in irrigated agriculture: confronting the livelihood and environmental realities.

Book cover for Wastewater use in irrigated agriculture: confronting the livelihood and environmental realities.

Description

This book contains 16 chapters aiming to better understand urban waste water use in agriculture in developing countries (Africa, the Middle East, Latin America and Asia), and detailed case study documentation of what works and what does not. It makes pragmatic recommendations aimed at protecting both the public health and farmers' income. This volume will be of significant interest to those workin...

A framework for a global assessment of the extent of wastewater irrigation: the need for a common wastewater typology.

Policies on wastewater use have tended to focus on treatment before use and the implementation of strict regulations. But in many low-income developing countries untreated urban wastewater is used for irrigation. Clear policy guidelines on how to optimise the benefits and minimise the risks of this practice are lacking. A better estimate of the extent of wastewater irrigation is needed before the reality of its use can become an agenda item for policy and decision-makers. Secondary data and results of nationwide assessments should be aggregated to obtain a global estimate of use. For this, a common typology of wastewater use is needed that would need to address such aspects as: the direct use of urban wastewater versus the dilution of urban wastewater by natural surface water before use, the relative contributions of domestic wastewater, industrial effluent, and stormwater to urban wastewater, the extent to which the wastewater is treated, and the use of wastewater in formal irrigation schemes, or as informal irrigation by smallholders without external support or control. A typology of wastewater irrigation and a database structure for consolidation of results are proposed. It is intended that this should be developed into a framework for a global assessment of the extent and importance of wastewater irrigation.
