“…Previous studies from many countries show how improved productivity and policy interventions concerning land rights security have positive impacts on food security and deterring deforestation (Angelsen and Kaimowitz, 2001;Araujo et al 2010;Branca et al 2011;Chi et al 2013;Epule et al 2014;Fearnside 2001;Tachibana et al 2001;Tomich et al 2001). However, there are still knowledge gaps, especially in the relationships between and among the biophysical, economic development, sociocultural aspects, and effective policy responses (Carr 2008;Chomitz et al 2007;Damnyag et al 2013;Mattsson et al 2012;Pasgaard 2013;Pouliot et al 2012).…”

Deforestation issues are more problematic when indigenous (adat) communities, living within a forest, have lived there for many generations. These adat communities, who employ traditional land-use, are frequently accused of encroaching on the forest. To understand existing and future trends in the spatial patterns of the expansion of traditional land-use and deforestation, we conducted a case study in the Kandilo Subwatershed using mixed methods with image interpretation, spatial modelling and sociocultural surveys to examine the interrelationships between physical conditions, community characteristics and traditional land-use expansion. We investigated community characteristics through household interviews, communication with key informants, and discussions with focus groups. By using an area production model, we were able to analyze the effect of improved farming systems, policy intervention and law enforcement on traditional land-use expansion and deforestation. Based on our examination of a 20-year period of traditional land-use activities in adat forests, the evidence indicated that the steeper the slope of the land and the farther the distance from the village, the lower the rate of deforestation. Our study found that customary law, regulating traditional land-use, played an important role in controlling deforestation and land degradation. We conclude that the integration of land allocation, improved farming practices and enforcement of customary law are effective measures to improve traditional land productivity while avoiding deforestation and land degradation.

“…His focus is to examine the roles of preference (measured by the revealed preference approach) and spatial dependency in farmers' forest clearing using simulation (see also Brown, 2006). Tachibana et al (2001) develop a cultivation-intensity model that endogenizes the evolution of upland holdings (T) among Vietnamese farmers who combine upland shifting cultivation and lowland paddy cultivation:…”

“…Furthermore, fallow land is under the risk of being grabbed by neighbors. Tachibana et al (2001) examine how the proportion of cultivated upland land (inverse of fallow length), shifting cultivation area, and upland forest clearing are affected by a rich set of policies, such as lowland technological progress, lowland farm area, forest clearing cost, and upland tenure security, as well as output price.…”

“…Shifting cultivators commonly have usufruct of not only the cultivated land they have cleared, but also their fallow land; customary tenure of fallow land tends to be insecure, however, and this tenure insecurity influences their forest clearing and fallowing decisions (Otsuka & Place, 2001;Place & Otsuka, 2001;Tachibana et al, 2001). It is straightforward to revise equation (7) to characterize such an alternative customary tenure setting; then, soil fertility of cleared fallow forest is effectively determined by fallow length or the inverse of cultivation intensity, 1/b.…”
