Appropriate technology is a concept we believe in – it’s really the unifying theme of Appropedia. It’s about understanding the context, and choosing the technology (or technique, design or process) which is most appropriate to that context.
E.F. Schumacher, in Small is Beautiful, also talked about intermediate technology – neither primitive and unproductive, nor high tech and expensive or polluting. But is that the same as appropriate technology?
Having a fixed idea about the “right” scale of the solution or the “right” level of tech is a problem. Small-scale intermediate technologies can be wonderful – especially in remote settings. Other times, there’s a lot to be said for the efficiency of scale, especially the large-scale infrastructure in cities. Doing things at scale means being able to afford expertise, monitoring, and backup systems. And the person living in a compact, walkable city, sharing a (very large) public transit system, getting their water from a (large) water utility and buying green power from their (large) electricity supplier, may have a smaller footprint than someone living close to nature with small-scale solutions, with solar panels and (because they’re so remote) a car. (There’s a big dose of “it depends” in such a comparison.)
Small is beautiful, yes. But let’s not be fixated on small for every solution. I wouldn’t want Appropedia to become solely for DIY enthusiasts building their own home-scale tech. As a living appropriate technology knowledge base, with an active community (including many students) Appropedia can bring together wisdom on many issues – including not only home greywater systems, but also the big infrastructure and planning issues we face. The appropriate approach is to take each approach on its merits, without an ideology favoring big or small scale.
Small is beautiful… but sometimes big is also quite good looking.
