The Role of the Forestry Sector and Processed Forestry Industry on the Economy in West Java, Indonesia

International Journal of Environmental Problems, 2020, 6(1): 3-10.
DOI: 10.13187/ijep.2020.1.3CrossRef

Abstract:
The contribution of the forestry sector is still very small in the West Java region. The continuation of the forestry and processing sector needs attention to improve and develop the sector. This study aims to (1) analyze the role of the forestry sector and wood processing industry (2) analyze the effect of changes in final demand on the output of the forestry sector and the wood processing industry and (3) the right policy formula to develop the forestry sector in West Java. The method used in this study is the input output method supported. The data is sourced from the West Java Regional Development Planning Agency (Bappeda) in the form of a soft copy of the input output table where the year of publication is 2015. The results show the contribution of the forestry sector is only 0.85 % of the agriculture and forestry sector. The wood processing industry only grew by 0.04 % and the forestry sector only grew by 0.01 % if investment had increased between 5–10 %. The role of the forestry sector and wood processing industry can be improved if the government tries to pay attention to regulations that have the potential to overlap which inhibits the growth of investment and licensing of the forestry business and processing industry. The government also needs to involve the community in managing community-based community forestry areas. Benchmark prices need to be regulated to avoid the risk of price uncertainty that can harm society.

Remote Sensing Application in Mapping Agricultural Crop Areas and Monitoring Rice Maturity

International Journal of Environmental Problems, 2020, 6(1): 11-24.
DOI: 10.13187/ijep.2020.1.11CrossRef

Abstract:
Climate change has evolved in an unpredictable trend and droughts have occurred more and more severely in the central provinces of Vietnam. Determining the irrigated area and water requirement for various crops and the growth stage of each crop is an urgent need as water resources for irrigation are getting scarce year by year. This research examines the application of Sentinel-2 and Sentinel-1 images to map crop areas and identify the current development stage of paddy rice areas. The images are collected and pre-processed from 2017 to 2018 for Ha Tinh Province in Vietnam. The Maximus Likelihood method is used to interpret Sentinel-2 imagery for mapping agricultural crop distribution status. The research presents a new approach for identifying rice maturity using the Sentinel-1 image series. The Overall Accuracy (OA) and Kappa coefficient methods are used to evaluate the generated maps of the agricultural crop’s distribution status. This study shows the relationship between the Sentinel-1 VH band and the growth of rice. From the image bands, we could calculate the slope of the line correlating between the VH backscattering value and the growth time of rice. Along with the local planting schedule, rice life cycle, and simple deduction, we could determine the rice growth stage at each time of image acquisition. The result will be the input parameter for the irrigation management, monitoring and operating information system that is applied to Ha Tinh province for proper and effective irrigation. The results identifying the rice maturity progression are illustrated for Cam Hoa commune in Cam Xuyen district and Thach Hoi commune in Thach Ha district, Ha Tinh Province.

The World Maritime Oil Trade: One of the Main Causes of Oil Spills?

International Journal of Environmental Problems, 2020, 6(1): 25-33.
DOI: 10.13187/ijep.2020.1.25CrossRef

Abstract:
Oil is the main driver of the growth of modern economies due to its multifaceted use in transport, energy and manufacturing. The main objective of this work is to study the data on oil spills created by oil tankers over the past 50 years and to study the trend in oil trade and oil spill pollution in an attempt to analyze the state of environmental pollution during major oil disasters. The article also discusses the key factors in the occurrence of tanker oil spills and summarizes the strategy and directions for the development of the global marine transport industry to prevent future pollution of oil tankers. The analysis shows that the waters of the Atlantic ocean at the shores of Western Europe are most prone to the occurrence of major oil spill accidents. It is assumed that with an increase in the volume of oil transportation, the number of accidents of oil tankers will also increase. But, as shown by statistical analysis, this is not so. Oil transport is becoming safer, and even in absolute numbers, the growth in traffic is accompanied by a decrease in the number of accidents accompanied by the release of oil and oil products. This is achieved mainly through logistics solutions and technical measures.
