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
Expert Workshop:
Treated Wastewater Reuse in Agriculture in Durban
- Setting the Scence
- South African Strategy, Policy and Regulations
- Research Projects
- Durban Projects
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?
