Surface runoff and erosion depends on the type of land use applied. The objective of this research was to find out the rate of surface runoff and erosion from agroforestry land use types at Miu sub-watershed, Palu watershed, Central Sulawesi, Indonesia, 2016. The method used was the multislot divisor on a plot measured 22 m x 2 m with 3 repetitions in 3 types of land use with a slope of 25-40% (steep). The result showsed that the largest surface runoff amounted from non-agroforestry land use type (10-year-old pure cocoa) by 72.674 liters/ha, followed by teak tree-and cocoa based agroforestry system aged 10 years old amounting to 59.815 liters/ha and the smallest is Candlenut tree-and cocoa-based agroforestry system aged 10 years old by 45.983 liters/ha. The highest erosion was recorded from non-agroforestry land use type (10-year-old pure cocoa) by 4,125 grams/ha, followe...

Furthermore, the watershed approach is the basis of FLR evaluations, which include evaluations of hydrology, land erosion, and other environmental factors. Currently, sustainable FLR planning is in the development stage. The present research was conducted to identify the erosion hazard level as a result of FLR performed on the Tambun Watershed in Central Sulawesi, Indonesia. Analysis of the erosion hazard level was conducted using the USLE equation. The results of this research revealed that FLR performed in a community forest and nursery, where Paraserianthes falcataria and Palaquium obovatum trees had been planted, had not been able to reduce the rate of soil erosion. Happen increase in soil erosion from 955.63 ton/ha/year (prior to FLR) to 1,097.52 ton/ha/year (after FLR). This was because these two types of plants were broad-leaved. Therefore, selecting the right type of plant is necessary. In particular, needle-leaved plants should be used in FLR activities to minimize soil erosion.

Candlenut-and cocoa-based agroforestry system aged 10 was more effective to manage surface runoff and erosion rate.

Sasaran kegiatan RHL adalah lahan-lahan kritis yang berada di dalam dan di luar kawasan hutan.
Secara nasional, lahan kritis pada tahun 2013 mencapai luas 24,20 juta hektar yang terdiri atas seluas 19,56 juta hektar berada pada kelas kritis dan seluas 4,63 juta hektar berada pada kelas sangat kritis. Selanjutnya capaian kegiatan RHL dalam bentuk pemulihan di dalam dan di luar kawasan hutan, pada tahun 2013 mencapai luas 0,66 juta hektar dan pada tahun 2017 menurun hingga 0,20 juta hektar.
Pemulihan hutan rusak di dalam kawasan hutan dalam bentuk rehabilitasi hutan (reboisasi), dan di luar kawasan hutan dalam bentuk rehabilitasi lahan (penghijauan: hutan rakyat, hutan kota, penghijauan lingkungan), serta rehbailitasi mangrove, rehabilitasi sempadan pantai dan rehabilitasi kawasan rawa gambut, tampaknya belum mampu mengimbangi perkembangan lahan kritis. Karena itu dibutuhkan perencanaan RHL.
Buku ini memuat uraian teori dan aplikasi perencanaan RHL dengan pemanfaatan teknologi Sistem Informasi Geografi (SIG), mulai dari tahapan rencana teknik RHL, rencana pengelolaan RHL, rencana tahunan RHL hingga rancangan kegiatan RHL. Sehingga menarik untuk dijadikan bahan bacaan bagi akademisi dan para perencana pada perencanaan kegiatan RHL
