São estas o objecto dos Aparelhos de elevar a água de rega, que os autores dividem em três grupos fundamentais segundo a força motriz que os faz funcionar - os agentes naturais (vento e água), os animais e o homem -, subdividindo-os ainda segundo critérios morfológicos, questionando as suas origens e estabelecendo a sua distribuição no território nacional. O conjunto de tecnologias aqui descritas, ao mesmo tempo que permite ilustrar e formular questões no âmbito da organização técnica e social do trabalho, fala afinal ao leitor da sede de água que, nas sociedades camponesas, vive em simbiose com o elemento central das suas estratégias de reprodução social: a terra."]
