“…However, population growth and urban development have led to land conversion with less vegetated areas. In 1999, most areas belonged to the very dense vegetation class, while in 2019 they belonged to the low vegetation class (Zaitunah, et al, 2021). These findings provide reliable information in selecting the best agricultural management practices, which simultaneously increase agricultural productivity and reduce the GHG emissions, enabling climate-smart agriculture (Macharia, et al, 2021).…”

This study identified the spatial distribution pattern of the ambient air quality in the Yogyakarta Urban Area. It was performed to determine the distribution pattern of SO 2 , CO, and NO 2 concentrations for 2016-2019 (pre-pandemic) and 2020 (during pandemic). Furthermore, the spatial analysis was performed using the Inverse Distance Weighting interpolation method. This study proved that spatial modeling using this method has good accuracy, and it is easier to map the distribution pattern of ambient air quality. In 2020, most of the locations met the quality standard (62.64%). As a result, the SO 2 and CO parameters immediately showed that most conditions are satisfactory. In 2016, the SO 2 parameters met the quality standards at 74.24% of locations. In 2020, the number increased to 85.71%. In addition, the CO parameter reached the quality standard at 81.82% of locations in 2016 and a perfect level of 100% in 2020. This occurred due to the effects of the COVID-19 pandemic because most human and business activities decreased drastically. Therefore, all studies can be used as the basis for air quality modeling and post-COVID-19 predictions. This study is also important as a policy material in the monitoring and management system of ambient air quality in urban areas.

“…However, some residential areas also have a fairly good canopy cover of vegetation that gives a lush impression and adds comfort (Figure 3 and 4). Vegetation can provide advantages by contributing to raising environmental quality in urban area [10]. The existence of the vegetation cover will directly affect the Vegetation density in an urban area will be inversely proportional to the area of built-up land.…”

The population of Surakarta has increased, putting pressure on vegetation and increasing demand for land availability. The population reached 500,173 people in 2010. The population trend is increasing every year so that the need for land as a place to live and living facilities also increases. This study aims to analyze the relationship between canopy density and the urban index in a 5 year period (2010 – 2015). The method used in assessing the density of the vegetation canopy is the calculation of the Normalized Difference Vegetation Index (NDVI) and the urban index. The calculation of the two index values uses Landsat 8 OLI satellite image data in 2015. The results show that the value of canopy density is inversely proportional to the value of urban index. The higher value of canopy density in Surakarta is followed by the lower value of urban index. The relationship between both is very close, marked by very high correlation and determination coefficient values, namely -0.98 and 0.97. Research on canopy density and urban index on a regular basis is expected to be part of the process of monitoring and evaluating urban area development and as input for local governments in the decision-making process.

“…According to [9] was also used Landsat to assess the land cover change and urban growth trend. Many studies used Landsat for land use and land cover detection and change analysis [56]- [59], [23], including in vegetation change analyse within some areas [60]- [63].…”

The increase of population has caused land use land cover change. The development of a city has increase the need of settlements and buildings. Monitoring any land cover is important to support environmentally based and sustainable urban planning. Medan as one of big cities in Indonesia has showed a development of the areas. The aim of the study was to analyze the land cover and vegetation existence in two sub-districts of Medan. The supervised classification analysis was conducted for year 2019. Ground check was a part of the study. There were six land cover classes found in the area, namely paddy fields, grass, shrubs, trees, mixed plant, and built-up land. The largest area within two sub-districts is built up areas. The results show less vegetated areas within two sub-districts. There was 86% of built-up areas in Medan Baru and 69.3% in Medan Selayang. Vegetation as an important element in the environment needs to be preserved within the urban areas. There is a need to plant trees in less vegetated areas. Green open space should be incorporated into city planning in order to preserve and improve the quality of the urban environment.
