4.1.2. Land-use and Planted Area by Major Crops
Much of the land is within reach of the river and human settlements spread over most of the lowland peneplain. Small groups with a huntergatherer lifestyle
suku dalam, orang rimba or indicated with the derogatory name Kubu which literally means confined continued to make a living in the core forest areas of the
interfluves, exchanging forest products for rice with surrounding villages. In the second half of the 19th Century rubber was introduced from Brazil; it thrived in the
same soil and climate of Sumatra and rapidly replaced all local, partially domesticated, latex producing trees and vines. In the beginning of the 20
th
century, extensively managed rubber agroforests Gouyon et al., 1993 replaced the shifting
cultivation systems of local food production and became the dominant land-use in the lowland peneplain of Jambi, as well as neighboring provinces. This attracted labour
from Java and elsewhere in Sumatra, especially during the initial boom in rubber after World War I. The main reason for the economic success of rubber at the time was the
abundance of cheap labour, the good access, harbors and trade system and the absence of rubber tree diseases. Rubber fitted easily into what was essentially still a
long-fallow shifting cultivation system based on upland rice as major food crop. Therefore, the transformation of the forests into agroforests was facilitated by the
local rules that assigned property rights where trees had been planted, while shifting cultivation plots without planted trees returned to the community land pool after the
cropping years.

Characterization of land-use change in Jambi was first carried out by multidisciplinary research teams that took part in the global Alternatives to Slash-
and-Burn ASB project, followed by a comprehensive comparison of land-use options Van Noordwijk et al., 1995, 1998; Tomich et al., 1998, 2001. In this
overview, Jambi Province is placed within the context of transect for global land-use change research, that was established by a consortium of national and international
research organizations. The transect offers a laboratory for understanding the ongoing land-use change. It also offers an opportunity to study agroforests as a land-
use system that is distinctive in the degree to which allows for a cohabitation of biodiversity and directly productive trees. The term ‘agroforest’, as defined by de
Foresta and Michon 1996 captures the mixed heritage of the ‘wild’ and the ‘domesticated’ aspect of these systems, and highlights an intermediate stage between
natural forest and agricultural plantations. Agricultural production in both villages is limited to a few food crops and
perennial crops Table 9. Rice was cultivated on rain-fed land as no irrigation had been constructed. Other crops such as cassava, sweet potatoes and corn were also
grown for complementing rice as an important subsistence to large number households.
Rubber occupied the largest part of agricultural land in both villages. In 2007 area planted with rubber in Senamat and Muara Kuamang villages were 406ha and
445ha respectively. Clearly the economics of these two villages were very much influenced by rubber production activities.
