| Animal-Drawn Wheeled Toolcarriers: Perfected yet Rejected |
|6. Experience in Latin America: 1979-1986|
In Chile, Jean Nolle adapted his Tropicultor design for the use of horses in 1969 and some NIAE toolcarriers were tested in the early 1970s. In 1985, a single Sahall wheeled toolcarrier was sent to the University of Conception for evaluation. This University continued its research interest in wheeled toolcarriers and in 1986 was working to develop a horse-drawn toolcarrier suitable for use in Chile.
Jean Nolle visited Paraguay in 1977. Following successful demonstrations of a Tropicultor in use, a coordinating committee to introduce wheeled toolcarriers in Paraguay was formed in conjunction with the United Nations Development Programme (UNDP) (Development Forum, 1978). It was envisaged that ten Tropicultors would be manufactured and tested in different parts of the country, with the technical support of Mouzon and finance from the French Government. It was considered that the Tropicultor would be ideal for increasing cotton and other agricultural production in the east of the country, as well as for developing the western semi-arid plain, the Chacao (Development Forum, 1978). Details how this scheme developed appear difficult to come by, but there seems no indication that it was markedly successful.
A small number of Mouzon Tropicultors were tested in El Salvador between 1977 and 1980 (Mouzon, 1978). Jean Nolle also visited Argentina, Colombia, Ecuador, Guatemala, Panama, Peru and Venezuela.
Some NIAE-type wheeled toolcarriers were tested in Colombia and in Costa Rica during the 1970s, but this did not lead to any promotion. A small number of Nikart toolcarriers were imported into Costa Rica for on-station evaluation. One of these was adapted as a research implement for measuring the work output of draft animals during transport and cultivation operations (Lawrence and Pearson, 1985).
In 1984 the ICRISAT technical drawings of the Nikart were sent to Instituto Superior de Agricola in Santiago in the Dominican Republic and also to an individual in Bolivia, but by 1986 there had been no feedback from either country.
