Haitian Health Foundation not only involved in clinical and surgical healthcare but also in community awareness and empowerment.
The 'Happy House and Toilet' is particularly noteworthy and as a seasoned architect/planner I recommend HHF as the best practices for community building.
Sanitation is integral to public health and Haiti and disaster zones to grasp a proper development model - 'Happy House and Toilet' remain exemplary.
With further support it could be scaled up as a participatory, incremental sustainable settlement strategy.
HHF has been helping to meet basic human needs in Jeremie, Haiti for decades. While I cannot speak for the early years, I can say that HHF runs a lean - focused program under the capable direction of it's Center Director, Nadesha Mijoba, who understands international development and works to insure that appropriate successful models are in place in the clinical facilities and programs she directs. The Happy House, an effort to provide basic housing to families in need, balancing donor contributions with recipient inputs (harvested materials and labor), has already provided 3000 homes. Going forward, HHF will be adding the GSAP Microflush toilet to the Happy House and low cost WASH elements plus an inexpensive (~$50) solar system to provide lighting and phone charging. Donations to HHF have a lasting impact on the people and community they serve.
