“…LST in the Chuping area generally shows a significant difference (p ≤ 0.05) of a declining trend from year image 2015 to year image 2017 with an average temperature of 32.70 • C, 28.50 • C and 26.99 • C as seen in Figure 7c. It was found out that the land use type has a close impression on the LST [82], e.g., oil palm trees have a mean of 21.65 • C when the rubber crop had a higher LST of 21.62 • C [83]. In contrast, as urban areas showed higher temperature records in peninsular Malaysia where an average of 23.17 • C to 26.45 • C was observed [84].…”

Agricultural drought is crucial in understanding the relationship to crop production functions which can be monitored using satellite remote sensors. The aim of this research is to combine temperature vegetation dryness index (TVDI) and normalized difference water index (NDWI) classifications for identifying drought areas in Chuping, Malaysia which has regularly recorded high temperatures. TVDI and NDWI are assessed using three images of the dry spell period in March for the years 2015, 2016 and 2017. NDWI value representing water content in vegetation decreases numerically to −0.39, −0.37 and −0.36 for the year 2015, 2016 and 2017. Normalized difference vegetation indices (NDVI) values representing vegetation health status in the given area for images of years 2015 to 2017 decreases significantly (p ≤ 0.05) from 0.50 to 0.35 respectively. Overall, TVDI in the Chuping area showed agricultural drought with an average value of 0.46. However, Kilang Gula Chuping area in Chuping showed a significant increase in dryness for all of the three years assessed with an average value of 0.70. When both TVDI and NDWI were assessed, significant clustering of spots in Chuping, Perlis for all the 3 years was identified where geographical local regressions of 0.84, 0.70 and 0.70 for the years 2015, 2016 and 2017 was determined. Furthermore, Moran’s I values revealed that the research area had a high I value of 0.63, 0.30 and 0.23 with respective Z scores of 17.80, 8.63 and 6.77 for the years 2015, 2016 and 2017, indicating that the cluster relationship is significant in the 95–99 percent confidence interval. Using both indices alone was sufficient to understand the drier spots of Chuping over 3 years. The findings of this research will be of interest to local agriculture authorities, like plantation and meteorology departments to understand drier areas in the state to evaluate water deficits severity and cloud seeding points during drought.

“…The focus of greenspace discourse in Malaysia has shifted from beautification-dominated to recognizing UGSs as an essential part of urban infrastructure (Aziz et al, 2011). Research on UGSs in Malaysia is mostly focused on management (Aziz et al, 2011;Fatiah et al, 2021;Maryanti et al, 2017;Rasidi et al, 2012;Sreetheran & Adnan, 2007) as well as human health and well-being outcomes (Andrew et al, 2020;Aziz et al, 2012;Foo, 2016;Mansor & Harun, 2014, 2018Nath et al, 2018), while some concentrated on the uses of UGSs (Aziz et al, 2018;Malek et al, 2015) and ESs provided by UGSs such as biodiversity conservation (Karuppannan et al, 2014;Ridzuan et al, 2021) and reducing land surface temperature (Sheikhi et al, 2015). However, most studies mentioned above only focused on specific study sites.…”

Residents’ perceptions on ecosystem services (ESs) provided by urban green spaces (UGSs) are vital for developing sustainable cities. However, there has been limited research on this issue in Malaysia. The aim of this paper is to assess Malaysians’ perceptions on ESs provided UGSs and how their perceptions are influenced by different socio-demographic factors. We used a structured online questionnaire and obtained 645 responses on 16 ESs from regulatory, cultural, and supporting ES categories. Descriptive statistics and binary logistic regressions were used for data analysis. In general, city dwellers have high positive perceptions on ESs provided by UGSs. Their perceptions for global climate regulation, noise buffering, pest regulation, spiritual, and research and education services would likely to significantly increase as they grow older. Households with moderate income have significantly greater perceptions of microclimate regulation, air filtration and aesthetic services. Having non-tertiary level education would significantly lower their perceptions of global climate and microclimate regulation, spiritual, aesthetics, and recreational services. Tertiary educated residents with non-environmental degrees also showed similar associations. Infrequent visits to UGSs would likely to significantly reduce the perception of global climate regulation, noise buffering, runoff reduction, erosion control, spiritual, and aesthetics services. People living far (>5km) from the UGSs also have significantly lower perceptions of microclimate regulation, air filtration services. Suggestions are made to incorporate ESs related content in pre-university curriculum and establishing small parks in neighborhoods to improve knowledge and uses of UGSs. These findings would assist urban planners designing environmentally sound urban policies and thereby improving human wellbeing in the cities.
