Workshop Durban am 30.11. und 1.12.
Was bei uns an Selbstversorgung in den Städt nach dem 1. Weltkrieg als Kleingartenkolonien und Schrebergärten Verbreitung gefunden hat, ist auch für die Townships in Südafrika ein großes Thema geworden, und zwar unter dem Aspekt Obst und Gemüse aus stadtnahem Anbau - bewässert mit nährstoffreichem, gereinigtem Abwasser. Hier kommen jetzt Fachleute aus Afrika und Europa zusammen.

1st Durban Workshop on Treated Wastewater Reuse in Agriculture, Botanic Garden Conference Room, 30th of November and 1st of December

Invitation

You are cordially invited to attend the 1st Durban Workshop on treated wastewater reuse in agriculture
titled: “Expert Workshop: Treated Wastewater Reuse in Agriculture in Durban”, at the Botanic Garden Conference Room on 30 November and 1 December.

 

Participants

A selected group of about 40 to 50 experts and practitioners from relevant administrative, development and research institutions will contribute to and attend the interactive workshop.

 

Background

The increasing fresh water demand particularly in developing urban centres of the global south causes local water scarcity for peri-urban and rural areas.

Authorities are challenged to find a way to manage water supply and wastewater. Strategies for wastewater reuse can support the urban water management.

Wastewater of nearby settlements is a continuous, free and reliable source of nutrient-rich water for agriculture. The livelihoods of many farmers in developing and emerging economies rely on the use of wastewater. Despite the benefits of using wastewater for subsistent farming, there are some associated health risks for farmers and consumers of agricultural products.

Currently in Durban some agricultural projects have been implemented and more support of small-scale farmers and homestead gardening will occur. The concept to support the success and productivity of this food production with reuse of wastewater needs to be discussed.

 

Objectives and leading questions of the Workshop

This workshop provides the opportunity to establish communication, facilitate professional exchange and initiate co-operations between researchers, administrative authorities, agricultural practitioners and implementation organisations. It ultimately may lead to a support for implementing wastewater reuse in agriculture and thereby strengthen the agricultural production and food security.


The objectives of the workshop are to

* inform decision makers of international trends in the use of wastewater in agriculture

* view a range of agricultural projects in Durban

* identify different scenarios for reuse in Durban and to propose appropriate models for water reuse

* Kick-start one or two projects

* Article in WaterWheel

 

 

Leading questions:

·         How will wastewater re-use continue in future?

·         What needs to be done to support and to guide wastewater reuse?

·         Why wastewater reuse?

·         Benefits and risks of reuse?

·         What are technical and socio-economic aspects of reusing wastewater?

·         How far has a wastewater to be treated in order to re-use it safely?

·         Advice and information from experts in this field

·         What is the political perception and what are the administrative guidelines for wastewater reuse in agriculture on the national and local level?

·         Which key factors determine the reuse of wastewater in agriculture?

·         What would be possible in eThekwini in future?

·         Sustainability of project implementation?
