The UNEP Third Regional Workshop in Johannesburg, South Africa in September 2012 addressed challenges and solutions related to safe wastewater use in agriculture. Key issues included institutional coordination, legal aspects, lack of data, and capacity building. Lessons highlighted the rising importance of wastewater as a resource, the need for multi-barrier sanitation approaches, and economic tools to promote safe wastewater use. Financial incentives, integrated models, and innovative technologies were emphasized for sustainable practices.

Synthesis of the 3rdSUWA 26-28 September 2012 Dr Birguy Lamizana, UNEP Third Regional Workshop Safe Use of Wastewater in Agriculture , 26-28 September 2012, Johannesburg, South Africa
Experiences from countries 20 countries (Botswana, Burundi, Ethiopia ,Ghana, Kenya, Malawi, Mauritius, Mozambique, Liberia, Lesotho, Namibia, Tanzania/Zanzibar, Uganda, Seychelles, Somalia, South Africa, Swaziland, Zambia) Challenges: Institutional aspects ( coordination, synergies) Legal, policy aspects (existence, implementation, enforcement) Lack of data on Wastewater Capacity building (technical, financial, human, ) Solutions/Needs: Proper institutional setting and strengthening Guidelines on SUWA Financial & environmental models and or incentives Awareness to overcome the taboo/WW and Safe use the wastewater, Platform, networking & experience sharing
Lessons learnt Importance of Wastewater is gaining momentum & Wastewater can be considered as a valuable resource Drivers: Water Scarcity Pollution/Tourism where availability is not a problem Nutrients from Wastewater as fertilizers Putting key institutions & stakeholders together is a key Clarifying institutional roles & responsibilities is a must for joint collaboration, Data/Diagnosis on the status of WW production treatment & use, and water quality status is important to identify; Financing & cost recovery in REUSE projects is a challenge that need to be addressed; Health & environmental risk assessment & mitigation need to be addressed in broad perspective
Lessons learnt Need to: Move from strict discharge standards to multi-barriers along the sanitation chain (practical tools to implement WHO 2006 Guidelines) Find economic tools to better inform and drive changes (behavior) to promote safe use of wastewater Have appropriate technologies and new approaches Adapted to the scale, situation & cultural background Constructed Wetlands as natural infrastructures can be a solution Have financial incentives to enforce policies and adopt appropriate technologies Have integrated economic and environmental models;
Way Forward? Some ideas Institutional mapping (baseline on where to start), Situation analysis & needs assessment at country level, Networking, partnership & policy dialogue Provide a platform for the development of new and innovative technologies & management practices Capacity building: Basic online training; Replicability at national level What else?
