Challenge Entries

iDE’s stimulates the private sector to create demand for latrines and strengthens the ability of local enterprises to meet that demand.

Plus de 80 % des Cambodgiens vivent sans latrine. Grâce aux subventions, la demande en toilettes baisse et les marchés privés des installations sanitaires sont entravés. Sans installations sanitaires correctes, les maladies diarrhéiques tuent plus d'enfants que le VIH, la malaria et la tuberculose réunis. Face à cela, IDE Cambodia a développé une latrine commercialisable qui permet aux foyers ruraux d'acheter des latrines quel que soit leur revenu.

Mais de 80% dos cambojanos não têm latrina; subsídios reprimiram a demanda por banheiros, frearam o mercado de saneamento privado e desanimaram um senso de propriedade. Sem saneamento básico adequado, doenças diarréicas matam mais crianças do que HIV, malária e tuberculose juntas. Como solução, o IDE-Camboja utiliza o design centrado no humano para desenvolver uma latrina comercial com preço acessível a todas as famílias rurais.

Más del 80 % de los camboyanos no tienen letrinas. Sin un saneamiento adecuado, enfermedades relacionadas con la diarrea matan a más niños que el VIH, la malaria y la tuberculosis juntas. En respuesta, IDE Cambodia utiliza un diseño antropocéntrico que desarrolla letrinas comercializables para que todas las viviendas rurales, más allá del ingreso, puedan acceder a una letrina. Esta solución de saneamiento sostenible busca el aporte de todas las partes interesadas en todas las etapas, desde los conceptos iniciales, refinamiento y prototipo hasta la decisión final.

Over 80 % of Cambodians do not have a latrine; well-meaning subsidies have depressed demand for toilets, stymied private sanitation markets, and discouraged a sense of ownership. Without proper sanitation, diarrheal illnesses kill more children than HIV, malaria, and tuberculosis combined. In response, IDE-Cambodia used human-centered design to develop a latrine that enables all rural households, regardless of income, to purchase latrines.
