1. Preface/Introduction We are pleased to share with you the scholarly papers that were presented during the 2nd International Conference on Environmental Sustainability and Resource Security (IC-ENSURES 2022), which was held virtually on March 8 and 9 in Johor, Malaysia, at Universiti Teknologi Malaysia. This conference was held concurrently with the International Seminar on Science and Technology (ISSTEC) 2022.Centre for Environmental Sustainability and Water Security (IPASA) organises the IC-ENSURES conference series every two years. To foster information and knowledge exchange on resource security and environmental sustainability, this conference series intends to establish a global forum for professionals and academics. This time around, the theme of the conference is “Green Technology for Sustainable Future: The Next Step”. This theme is pertinent to environmental issues, disaster preparedness, and water security.With the global pandemic happening around the world, we are particularly interested to see how COVID-19 would affect our water and environment. Additionally, natural catastrophes, particularly those associated with climate change, have become more common and severe in recent years due to anthropogenic activities. Putting that in mind, the themes and topics of IC-ENSURES this year were carefully designed so that they associated with the ongoing pandemic and climate change.Engineering-related sessions including discussions on the following two major topics: environmental sustainability and resource security were carried out. These manuscripts were subjected to a rigorous review in compliance with international publication standards. We anticipate that the collection of accepted manuscripts will benefit numerous academicians, researchers, and experts in a given topic.List of Conference or sponsor logo, committees are available in this pdf.
