Diarrhoea prevalence is extremely high in Nias, especially in Alasa and Afulu sub-districts, with diarrhoea rates of 45% and 35 % respectively, compared with 11% for Indonesia nationally.
In the nine months up to the end of March this year, our efforts in Nias have been focused on Community-led Total Sanitation (CLTS). Communities are encouraged to make an honest assessment of the status of their own community sanitation, with one of the key outcomes being the construction of latrines by individual members of the community.
In many parts of Nias, communities have embraced this opportunity being offered by SurfAid, and the table below indicates the extent to which our partner communities in Afulu and Alasa have responded.
Eight individual communities were introduced to CLTS between May and August 2009. During the initial introduction (called triggering) a total of 231 households agreed to build their own latrine. We have followed up with these villages since then, and have provided some technical and logistical support to assist them in the design and building process.
These communities were formally re-assessed during March 2010, and the results have proven to be very impressive. After committing to 231 latrines, these communities have collectively built 255 to date, and there are several in each community still under construction. Hilina'a demonstrated the lowest completion rate (74%) and Lolomboli was highest (162%).
Meanwhile five additional communities (one in Afulu and four in Alasa) which were triggered in November and December 2009 have committed to build a total of 108 latrines. To date they have successfully completed 65 (60%). Over the course of the next few months we will continue to follow up and report on the progress of all of these 13 individual communities, and will also report on how CLTS is implemented in other communities in Nias.
