Abstract

This study is objected to determine the options for land conservation based on degraded land in upland of Luas watershed, Bengkulu, Indonesia. This work was conducted on the upland from November 2015 to February 2016. The location was geographically lying on 103 0 20’47” - 103 0 58’50” Latitude., and on 04 0 21’10” - 04 0 37’12” longitude, in Kaur District, Bengkulu Province. The total area is 55,045.23 ha where the forest covers 52,432.95 ha or 95% of the upland of Luas watershed. The spatial analysis for land degraded level was based on overlaying from attributes of some parameters such as; land cover, slope, erosion hazardous level, land productivity and management. The analysis is conducted by converting analytical geographical coordinates into Universal Transverse Mercator (UTM). The upland of the watershed is currently under environmentally pressures which around 24% in poor conditions and 23% of the area are degraded. The Limited Timber Forest areas of Air Kinal, Kaur Selatan, and the protected forest area of Bukit Raja Mendara can potentially be rehabilitated by applying concepts of social forestry with introducing agro-forestry cultivation models. All areas of agriculture cultivation in this study can be effective using land conservation tillage and management which concerning all environmental values for the sustainable productivities.

Highlights

Watershed in a hydrological concept is an important element in the water management system
A number of 222 watersheds are in the second priority due to poor environmental values, and 176 of the Indonesia watersheds are in the third priority
The upland of Luas watershed mostly covers by forest area of 52,432.95 ha, or of 95.25% of total area in the watershed

Summary

Introduction

Watershed in a hydrological concept is an important element in the water management system. Increasing degraded land productivities within forest areas and agriculture cultivated land is in the down- and middle-stream areas and continuous encroachment to upland watershed. It is known, that the watershed degradation have been tirggered by increasing exploitation of natural resources due to rapid population, economic growth, lack of experiences in watershed management and practices [6]. In the management planning and integrated conservation practices, it requires some important strategies and innovative actions in order to improve and maintain the land productivities and watershed surrounding values [7]
