Ngade Lake is surrounded by steep cliffs with a very high level of erosion insecurity with a very steep slope > 45% without sloping edges and no outlets. In the upstream region the water catchment area of Ngade Lake is dominated by land use in the form of coconut and nutmeg plantations. This study aims to examine the form of land evaluation strategy to maintain forest function from erosion threat in the area of Ngade Lake water catchment with agroforestry management pattern. The method used in this research was a quantitative descriptive method using field surveys to collect data on the characteristics of the land that is assisted by secondary data from various literature. The collection of land characteristics data was done at each observation point. To collect the primary data used sampling techniques carried out with stratified random sampling method considering accessibility of roads. The results of the study showed that there were several classes of land capacity. Among them were Class II with high potential of land so it can be cultivated for agriculture and settlements. Land capacity Class VI and VII with low-potential land or difficult to be cultivated for agriculture, this land capacity class intended for forestry plants and grazing fields.
The livelihoods of people in small islands are never disconnected from socio-economic problems and the degraded environment. In the long term, the living system will influence the surrounding environmental condition if the environment utilization is not sustain managed. This research aimed to assess the people's livelihood assets to encourage the living quality of local people. Qualitative and quantitative methods were implemented to analyze the data from questionnaires in deeply direct interviews. The variables to evaluate in the livelihood assets condition consisted of human capital, natural capital, social capital, physical capital, and financial capital, which covered the sampling region in South and North Maitara island. The basic capital of people's livelihood is presented as Pentagon Assets, and its strategies are grouped into intensification, extensification, and migration. The result showed that the component of livelihood capital assets depending on natural capital was 8.99, financial capital was 9.88, physic capital was 12.38, human capital was 15.06, and social capital was 16.64. The intensification and extensification consisted of the percentage of yard utilization was 11%, agriculture land utilization was 37%, empty land utilization was 24%, and arable land utilization was 12%. Moreover, migration as part of livelihood strategies in this region composed of permanent migration was 15%, and circular migration or commuter was 45%. In conclusion, agricultural land utilization is still dominant for local people, exerting circular migration to sustain their subsistence.Keywords: livelihood assets, sustain, environment utilization, small island
