Many farmers participated in order to receive incentives (food,wages, seed, and/or tools) provided by the agencies promoting the rehabilitation of raised fields. As we will see below, the use of incentives can have a negative effect on continued cultivation of rehabilitated raised fields and contribute to field abandonment. Some cases of spontaneous adoption
(without incentives) by curious individual farmers are documented (Erickson and Brinkmeier 1991; Pari, Aguilar, and Cutipa 1989:35–36;PIWA 1994:52).
