Evaluating Forest and Land Rehabilitation Using Remote Sensing: A Case Study in Maros Regency
Get PDFRemote sensing technology has become crucial in vegetation monitoring, particularly for assessing vegetation density. Despite its broad application, its use in evaluating land rehabilitation efforts remains limited. The increasing extent of degraded lands has underscored the importance of effective forest and land rehabilitation activities. Traditionally, evaluating these efforts involves direct site visits to monitor plant growth annually for three years post-planting, which is time-consuming, labor-intensive, and costly. According to rehabilitation standards, a program is successful if 75% of the planted vegetation survives until the end of the third year. This study presents an efficient alternative by evaluating a rehabilitation site in Maros Regency, using remote sensing technology to monitor planting success over periods of 15 years (2007), nine years (2013), and three years (2019). The evaluation utilizes multispectral drone imagery and Normalized Difference Vegetation Index (NDVI) analysis to assess vegetation density through multi-temporal analysis across wide areas. The findings reveal that the percentage of forested areas after three, nine, and fifteen years of rehabilitation activities was 24.6%, 3.1%, and 23.5%, respectively. This research demonstrates the potential for further application of Unmanned Aerial Vehicle imagery in monitoring the success of land rehabilitation projects

ABSTRACT
Cendrana Farmer Groups 1 and 2 face the challenge of low rice productivity due to the use of low-quality seeds and the lack of seeds that are adaptive to climate change. This is due to the limited availability of superior seeds in the Barru District. As a solution, Cendrana Farmer Groups 1 and 2 were trained to produce early-maturing rice seeds more resilient to climate change. This community service activity aims to increase farmers\u27 income and support seed independence by producing early-maturing rice seeds in Cendrana Farmer Groups 1 and 2. The methods applied include socialization of the service program, training in superior seed production from the beginning to seed marketing farmer groups are trained to produce compost from organic resources, and assistance in making rice seedling demonstration plots. The results show that Cendrana Farmer Groups 1 and 2 can now produce seeds independently and increase yields. In Cendrana Farmer Group 1, the yield of the Cakrabuana variety increased from 3.05 tons/ha (control) to 4.14 tons/ha after fertilization, while in Cendrana Farmer Group 2, the yield of the Padjajaran variety increased from 5.2 tons/ha (control) to 6.7 tons/ha. The income that was initially IDR. 550,000,000 is now IDR. 1,265,000,000 This program significantly contributes to the increase in rice productivity and superior seed independence in the Regency.
