Abstract: |
The poorer half of the world's people have long relied for theirenergy needs on woodfuels. Since the oil shocks of the 1970s,pressure on forest resources has increased and the costs oftraditional use of woodfuels have been growingto thehouseholder, in cash or collection time, and to society in inefficientenergy use, deforestation, and local and global harm to healthand the environment. Modern, efficient stoves can alleviatesome of these problems; programs to design and disseminate themwould seem a worthwhile pursuit for development activity. But do such programs in fact warrant the investment? Why haveso many failed to catch on as expected? The authors find thatprograms have been most successful when targeted to specificareas where woodfuel prices or collection times are high. Fieldtesting, consumer surveys, and involvement of local artisansfrom the outset have been critical to the ultimate adoptionof the stoves. With these elements in place, external supportfrom governments and donors can be useful; lacking them, subsidiesmay succeed only in distributing stoves that ultimately molderaway unused. This article's review of what makes for successand failure is instructive for the design of stove programsin particular, and of development projects that propagate improvedmethods and technologies in general. |
