Further to my blog of 6 April, I’ve found the slides I took in July 1980 of the experimental/demonstration fossas migratórias (‘migratory pit latrines’) at the Instituto Nacional de Pesquisas da Amazônia in Manaus in the Amazon rainforest in Brazil. Here’s a couple − the first shows a general view of one of these fossas and the second shows it on the move (and you can see it’s a bit like a sedan chair). In the shallow soils of rainforests these latrines need to be moved every three months or so in order to induce the tree to grow strong lateral roots, but elsewhere it’s obviously better (and simpler) to have Peter Morgan’s Arborloos − why, in poor dispersed rural areas (and most dispersed rural areas are poor/very poor), would we want to promote anything else? Now there’s a question for EcoSanologists!
