    The Intersection between  One Health and WaSH The Intersection between One Health and WaSH Presentation Transcript

    • The Intersection between One Health and WaSH Prof. Dr. Janet Hering, Director GRF Davos One Health Summit Davos, Switzerland, 17-20 November 2013 Eawag: Swiss Federal Institute of Aquatic Science and Technology
    • An idea from 400 BCE “And I wish to give an account of the other kinds of waters, namely, of such as are wholesome and such as are unwholesome, and what bad and what good effects may be derived from water; for water contributes much towards health.” (emphasis added) Hippocrates (trans. F. Adams) On Airs, Waters and Places http://classics.mit.edu//Hippocrates/airwatpl.html
    • One Health includes "the environment" sanitation
    • but not sanitation
    • Why should we care? http://www.cdc.gov/nceh/vsp/pub/norovirus/norovirus.htm http://www.cruiselawnews.com/2012/11/articles/norovirus/norovirus-outbreak-on-royal-caribbeans-voyager-of-the-seas/ http://www.cruiselawnews.com/2010/02/articles/norovirus/can-sick-cruise-ships-cause-norovirus-outbreaks-in-ports/
    • Poor sanitation contributes to disease transmission in feces in urine http://www.onhealth.com/schistosomiasis/article.htm http://oneinsevenpeople.co.uk/urogenital-schistosomiasis/
    • Global sanitation coverage 1990-2010 (projected to 2015) http://www.unicef.org/media/files/JMPreport2012.pdf
    • The open defecation problem http://www.unicef.org/media/files/JMPreport2012.pdf
    • No shortage of sanitation technologies http://www.eawag.ch/forschung/sandec/publikationen/compendium_e/index_EN
    • Technology is not enough – an enabling environment is also necessary government support social and cultural acceptance legal and regulatory framework implementation of technical solutions financing Two examples institutions skills and capacities 1. Promoting good hygiene 2. Converting waste to a resource Source: Sandec/Eawag
    • Example 1: Good hygiene practices http://water.worldbank.org/shw-resource-guide/sanitation-and-hygiene-why-they-matter
    • Haitian earthquake – cholera outbreak http://www.cdc.gov/mmwr/preview/mmwrhtml/figures/m5948a4f2.gif http://i.dailymail.co.uk/i/pix/2010/01/15/article-1243540-07DCFE9B000005DC-496_964x659.jpg
    • Good hygiene is an important part of cholera prevention What activities are effective in promoting hand washing? http://www.unicef.org/cholera/
    • Promotional activities used in Haiti effect on handwashing faeces-related positive Radio spot  Radio program negative food-related positive negative   Announcement using megaphone Group discussion Hygiene training  Home visit Demonstration and material distribution   Information from neighbor   Focus group   Cinema show  Theater  Special hygiene day Quiz Stickers/posters/paintings   Community club Hygiene songs   Contzen and Mosler (2013) J. Public Health, DOI 10.1007/s10389-013-0577-4 activity
    • Behavioral factors and corresponding change techniques R A N A S http://www.eawag.ch/forschung/sandec/publikationen/general/dl/sandec_news_13.pdf
    • Example 2: Converting waste to a resource closing the loop "one-way" nutrients are lost the environment is polluted nutrients are recovered the environment is protected
    • Dry toilets in Durban, South Africa Urine discharged to soil • loss of nutrients • (eventual) pollution of groundwater Contact: Kai.Udert@eawag.ch
    • VUNA - Nutrient harvesting in South Africa Project elements • Reactor technology • Network management • Socio-economic opportunities Cooperation with eThekwini Water and Sanitation and the University of KwaZulu-Natal http://www.eawag.ch/forschung/eng/gruppen/vuna/index_EN
    • Alternative models for urine collection Institutionalized approach • utility collects urine from households Incentive approach • households are paid to drop-off urine tanks at a collection point
    • Pilot studies and optimization Institutionalized approach Pilot study (2012-2013) Incentive approach 1.6 ZAR per liter Urine collected 600-700 liter per round (45 households) Urine produced by household (3 liters per day) 2100 ZAR per household per year Optimized system (start 2014) 2 ZAR per liter 1100 ZAR per household per year (Preliminary results) Work in progress 0.8 ZAR per liter 590 ZAR per household per year Challenges – difficult terrain, rural area with long distances, limited acceptance of dry toilets, low usage and limited urine production Optimization potential – institutional: transportation frequency and distances, the collection procedures; incentive: number and density of collection points, monetary incentive per household VUNA Meeting September 2013: Elizabeth Tilley, Theresa Rossboth, Hope Joseph, Heiko Gebauer
    • Costs of alternative sanitation systems Dodane et al. (2012) Environ. Sci. Technol. 46: 3705-3711. http://www.susana.org/images/documents/07-cap-dev/b-conferences/12-FSM2/p2.1-fsm2-strande-eawag-switzerland.pdf
    • Little (SB) or no (FSM) valorisation of endproducts Dodane et al. (2012) Environ. Sci. Technol. 46: 3705-3711. Distribution of costs
    • Opportunity for valorisation through use as fuel http://www.eawag.ch/forschung/sandec/publikationen/general/dl/sandec_news_14.pdf
    • Pilot-scale project with industry http://www.susana.org/images/documents/07-cap-dev/b-conferences/12-FSM2/p2.1-fsm2-strande-eawag-switzerland.pdf
    • Concluding comments The importance of sanitation and hygiene as key components of One Health deserves greater recognition, promotion and study. Adequate sanitation and hygiene require good technologies and technological concepts but ALSO an enabling environment. Enabling and incentivizing sanitation and hygiene can profit from good business models and financing plans, including valorisation of end-products.
