    Equatorial warming conditions in urban areas can influence the particle number concentrations (PNCs), but studies assessing such factors are limited. The aim of this study was to evaluate the level of size-resolved PNCs, their potential deposition rate in the human respiratory system, and probable local and transboundary inputs of PNCs in Kuala Lumpur.

    Climate change interacts in a different way with varieties of human activities and other drivers of change along coastlines. Sea level rise (SLR) is one of the major impacts of global warming. Changes in climate extremes and SLR may impact the critical infrastructures such as coastal road, jetty and chalets as well as the local community. The population and assets exposed to coastal risks will increase significantly due to population growth, economic development and urbanization in the future. As most of the cities in Malaysia are situated near the coast, immediate actions are needed to minimize the undesired outcome due to the SLR.The main objective of this study is to identify physical variables that may have impacts on the coastal area, thus develop a coastal vulnerability index (CVI) for the East Coast of Peninsular Malaysia. Seven (7) physical variables have been identified to assess the CVI that consists of geomorphology, coastal slope, shoreline change rate, mean significant wave height, mean tidal range, relative sea level rate and land use.

    Current and potential impacts of sea level rise in the coastal areas of Malaysia
    (IOP Publishing, 2019) Sofia Ehsan; Rawshan Ara Begum; Nor Ghani Md Nor; Khairul Nizam Abdul Maulud
    Sea level rise is one of the most concerning and costly effects of climate change that impacts the sustainable development of coastal areas. Malaysia, representing 13% of the total land area within 5 km of a coast, is threatened by the devastating impacts of sea level rise. This study attempts to highlight the current and potential impacts of sea level rise in several high risk coastal areas of Malaysia. Currently, coastal erosion and coastal flooding are the major effects of sea level rise impacting the important coastal infrastructure. The coast of Selangor and Batu Pahat experienced severe coastal erosion recording the total eroded area of 1878.5 hectares and 415.47 hectares respectively. Likewise, the coastal flooding in Johor coastal flood was damaging an estimated RM 0.35 billion worth of infrastructure and RM 2.4 billion of economic losses.

    Effect of projected sea level rise on the hydrodynamic and suspended sediment concentration profile of tropical estuary
    (Elsevier, 2018) Shahirah Hayati Mohd Salleh; Anizawati Ahmad; Wan Hanna Melini Wan Mohtar; Chai Heng Lim; Khairul Nizam Abdul Maulud
    Kuala Pahang, an estuary located in the East Coast of Malaysia is projected to experience a 0.03, 0.14 and 0.31 m increase in sea level in the years 2020, 2060 and 2100, respectively. To predict how tide and current speed affect suspended sediment concentration, the MIKE 21 HD and ST models were used to simulate the hydrodynamics and sediment transport at Kuala Pahang. The study is limited to the Southwest Monsoon period and the model was conducted as a localised analysis at the Kuala Pahang estuary.

    The Southeast Asian (SEA) region is no stranger to forest fires - the region has been suffering from severe air pollution (known locally as "haze") as a result of these fires, for decades. The fires in SEA region are caused by a combination of natural (the El Niño weather pattern) and manmade (slash-and-burn and land clearing for plantations) factors. These fires cause the emissions of toxic aerosols and pollutants that can affect millions of people in the region. Thus, this study aims to identify the impact of the SEA haze on the Southern region of the Malaysian Peninsula and Borneo region of East Malaysia using the entire air quality observation data at surface level in 2015.

    Extensive assessment of climate change impacts on coastal zone paddy growth using multispectral analysis and hydrodynamic modeling
    (Elsevier, 2023) Samera Samsuddin Sah; Khairul Nizam Abdul Maulud; Othman A. Karim; Suraya Sharil; Zaher Mundher Yaseen
    Global warming has led to sea levels raise (SLRs) and Malaysia is no exception to this problem. Especially for low-lying coastal areas including the Kuala Kedah area which is active in agricultural and fisheries activities. Farmers have had to bear up to 75 % of yield losses due to seawater breaches since 2016. Therefore, this study is designed to assess the impact of seawater encroachment on water quality through spatial technology approaches and hydrodynamic modeling related to the growth of paddy trees.

    Household external vulnerability due to climate change in Selangor coast of Malaysia
    (Elsevier, 2022) Sofia Ehsan; Rawshan Ara Begum; Khairul Nizam Abdul Maulud
    This study attempted to evaluate vulnerability mapping of the coastal areas due to climate change using an integrative external and internal framework from three dimensions at the household level: exposure (E) to coastal hazards, sensitivity (S) due to demographic, socio-economic and structural characteristics and adaptive capacity (AC) relating to available assets and adaptive behaviour to cope with climate change impacts.

    Southeast Asian haze is a semi-natural phenomenon that chokes the region each year during the dry monsoon season. Smoke-haze episodes caused by the vegetation and peat fires in Indonesia severely affected large parts of Malaysia during the 2015 El Niño phenomenon. This study aimed to evaluate the factors that influenced the concentrations of aerosol and trace gases during the 2015 haze and non-haze period on a semi-urban site in the southern part of Malaysian peninsula that facing Sumatra (Muar, Site A), and on an urban site near to Kuala Lumpur, influenced by the city centre (Cheras, Site B).

    (Department of Civil Engineering, Faculty of Engineering, Universitas Andalas (Unand), 2020) Arniza Fitri; Khairul Nizam Abdul Maulud; Dian Pratiwi; Arlina Phelia; Farli Rossi; Nur Zukrina Zuhairi
    The issues of freshwater pollutions and the high demand of clean freshwater for daily human activities have forced developing countries such as Malaysia to continuously monitor the quality of the freshwater. The present study objective is to present the trend of water quality status in the Kelantan River downstream, Peninsular Malaysia from 2005 to 2018. Water samples were collected during dry and monsoon seasons from a sampling station located at downstream of the Kelantan River. Water quality parameters such as temperature, pH and dissolved oxygen (DO) were measured in situ while other parameters were analysed in the laboratory based on retrieved water samples.
