“…Reasons for non-adoption and adaptation of SC technologies * Farmers feel that they are unlikely to reap expected benefits because of a lack of secure access to land (Bunch, 1982: 45;Sanders, 1988;Comia et al, 1994;Wachter, 1994). * Labour costs involved in establishment and maintenance of technologies are too high, especially if farmers periodically work off-farm (De Janvry et al, 1989;Douglas, 1993;Zimmerer, 1993;Critchley et al, 1994;Stocking, 1995;Garrity et al, 1997;Lal, 1989). * Technologies do not reliably reduce soil loss and, even if they do, the reduction does not, immediately, raise yields (Pretty, 1995: 51).…”
