| dc.description.abstract | Karang Mumus river basin zone covering 32,196.3 ha is river basin in East Kalimantan is
classified as higher level ofdamage with first priority. At present there is 9, 106 ha marginal area in
the river basin. Aim ofthis research was to evaluate and analyze driving factors for agroforestry
land'icape management in Karang Mumus river basin. Research conducted in Karang Mumus river
basin, a part of Mahakam Hilir sub watershed For that aims, we employed spatial and temporal
analysis, land suitability evaluation, social-economics and policy analysis. The evaluation resulted
land sUitabilityfor several land utilization. In the river basin land suitable for protected area was
classified as highly suitable (SI) covering 8,810.5 ha (27.1%); moderately suitable (S2) covering
12,805.4 ha (39.4%); marginally suitable (S3) covering 7,947.5 ha (24.5%); not suitable (N)
covering 2,936.6 ha (9.0%). Land suitability for conservation area was classified as highly suitable
(SI) covering 3,475.5 ha (10.7%); moderately suitable (S2) covering 682.3 ha (2.1%); marginally
suitable (S3) covering 647.7 ha (2.0%); not suitable (N) covering 27,694.5 ha (85.2%). Land
suitability for dryland agriculture was classified as highly suitable (SI) covering 20,009.7 ha
(61.6%); moderately suitable (S2) covering 2,237.9 ha (6.9%); marginally suitable (S3) covering
8,580.2 ha (26.4%); not suitable (N) covering 1,672.1 ha (5.1%). Land suitabilityfor agriculture of
wetland was- classified as highly suitable (Sl) covering 12,802.5 ha (39.4%); moderately suitable
(S2) covering 8,264.5 ha (25.4%); marginally suitable (S3) covering 2,381.0 ha (7.3%); not
suitable (N) covering of9,051.9 ha (27.9%). Land suitability for settlement was classified as highly
suitable (SI) covering 19,520.1 ha (60.1%); moderately suitable (S2) covering 2,745.7 ha (8.4%);
marginally suitable (S3) covering 362.9 ha (1.1%); not suitable (N) covering 9,871.3 ha (30.4%).
Based on social-economic analysis, resident's growth rate in Karang Mumus river basin was
4.9ro/year. Prediction of the population in the year of 2012 was 276,756 persons, geographical
density was 879 persons/lml, and agrarian density was reached 9 personslha. The driving factors
ofagroforestry landscape management in Karang Mumus river basin are policy, socio-economicsculture,
and physical-biology factors. The policy factor includes riverbanlc settlement relocation,
reforestation and critical land rehabilitation. The socio-economics-cuJture factor includes
population growth rate, cultural background ofthe society, andfeas-ibility ofagricultural business.
The bia-physical factor includes accessibility, compatihility of land utilization, and land use and
land cover change. | id |
