Dhaka Workshop January 2011www.HousingandHazards.org Slide
Housing & Hazards has been looking at ways of communicating better technologies for 15 years.
Housing development is an issue that affects everyone from the end-user to the decision-makers in Dhaka – different approaches are needed for different stakeholders.
This talk looks at some of the issues we have encountered through Action-Research at village level in Bangladesh.
Some issues may not be relevant now but could be borne in mind if resistance to innovation is encountered.
