Transcript of Research and Education: Growing with waste

Nexus Approach to resource management: Research and Education needs
Servicing the UN
Example: Ouardanine - Tunisia
First use of Treated Waste Water (TWW) in citrus orchards in La Soukra
Passing of law on re-use 1995
Expand area of TWW irrigation to other areas
Trial re-use of bio-solids (sewage sludge)
Research shows contamination of soil and crops
Establish national regulations (1989)
21st century
26 of the 110 existing waste water treatment plants in Tunisia are used for TWW irrigation
1. Reduce distance from WWTP to field

2. Make use of 'non-treatment' options such as drip-irrigation, intermediate storage, etc. to reduce health risks

3. Prioritize irrigation of critical crops (i.e. nurseries)

4. Vaccinate farmers

5. Regularly check quality of effluent, contamination of soils, and residues on crops
(What are 'good' levels?)

6. Build trusted interactions between farmers and agricultural extension officers

7. Raise awareness of consumers to reduce the 'yuck' effect
Drip irrigated
WWTP -- 1000m3/d
(1993) 17.000 people
(2015) 21.814 people
75 ha

(1997) 4000 m3
(2014-2015) 140.000m3 per year
