Preface

Against the backdrops of severe global climate changes and over-exploitation of physical developments around the world, the overall ecosystems, which comprise of human, animal, natural elements, and the interactions between them, were challenged by significant problems. From the likes of land subsidence, global warming, sea level rise, to the seasonal floods and drought, all are subject to sustainable development concerns. At both the global and local scale, stakeholders - ranging from governments to communities are encouraged to promote sustainability and environmental management actions that involve managing the oceans, freshwater systems, land and atmosphere, and the people and surrounding life according to sustainability principles. The global agenda like Energy Transition Policies, Environmental, Social, and Governance, and the Sustainable Development Goals emerged and facilitated global initiations and collaborations towards sustainable actions. In this regard, the spread of knowledge, the reproduction of innovation, and the mutual learning of tackling the issues are crucial to strengthening the global sustainable development actions and improving the stakeholders' capacity to support the commitment, which the academic conferences and seminars play an important role.

The International Conference on Environmental Management (ICEM) is one of the realizations. The event was based in Surakarta, Indonesia, on 24^th September 2022. The event was a part of the biannual academic forum initiated by the Environmental Research Centre (PPLH), the Institute for Research and Community Service (LPPM), Universitas Sebelas Maret (UNS). The event was a commitment of PPLH, UNS, to actively participate in the promotion of knowledge development and sharing on sustainable development issues both locally and globally. The ICEM comprehensively addresses sustainable development activities that relate on both land, water, air, and the society. The conference covers 14 issues from climate change to environmental pollution. Not only did facilitate discussions in terms of the phenomena and problems, the conference also allowed various discussions on sustainability-led public policy and environmental management affairs. The purpose of ICEM is to bring together all academics, researchers, and practitioners to reflect upon the current state of global sustainability issues and to seek mutual understanding and sharing on solutions to cope with the emerging environmental problems as well as to adapt with the on-going sustainability-led policies and actions. Nevertheless, the ICEM expects the knowledge gained from the event can be used as the fundamental sources of effective, integrated, and innovative decision making and actions towards sustainable development.

The ICEM was successfully held in time involving approximately 250 people from across the globe which represent various backgrounds consisting of environmental researchers, environmental engineers, lecturers, environmental practitioners, urban planners, activists, government elements/policy makers, as well as students and members of the public who concern on sustainability issues. Within the duration of 3 (three) months, from July to September, the ICEM facilitated (1) the arrangement of key speakers and keynote speakers with relevant expertise and international reputations, (2) the production of materials, leaflets and information, as well as (3) the design of seminars and thematic discussions and publications in proceedings. The final output of ICEM is published in the IOP Conference Series Earth and Environmental Science and Journal of Soil Science - Journal of Soil Science and Agroclimatology. Both publication bodies are well recognized and indexed by Scopus. The implementation of ICEM activities is supported by superior and professional committees who are members of the PPLH UNS.

Due to the COVID-19 pandemic, the ICEM was held virtually through a virtual platform Zoom Meeting hosted by the ICEM committee in collaboration with the Information Technology Team of Universitas Sebelas Maret. The majority of participants of ICEM which consist of Keynote Speakers, Invited Speakers, Paper Presenters, and General Participants as well as Audiences who registered through an online system (www.icem.uns.ac.id) were engaged in active sharing and discussions. Four keynote speakers delivered their materials, which include Professor Dr. Abdul Rahim bin Abdul Samad from the University Putra Malaysia who provided a general overview of the sustainability issues in Asia, Professor Dr. rer.nat. Junun Sartohadi from Universitas Gadjah Mada who shared their research on the current state and the dynamics of sustainability issues and rapid environmental changes, Indonesia, Dr. Wesam Al Madhoun from Gaza University of Palestine who discussed the issue from a case study of Palestine and its policy making complications, and Professor Dr. Pranoto from the host university, Universitas Sebelas Maret, who shared his insights on potential sustainability efforts at the local level through household-based technology. A total of 113 presenters were registered at the event and presented their material at the next session after the keynote. The presenters also submitted a total of 113 papers, all of which reported and discussed their findings and recommendations for action to promote sustainable environmental management. A total of 107 papers could be further reviewed for publication in proceedings, while the rest chose to be submitted to journals that collaborated with this conference.

After the review and editing process, a total of 55 selected papers were then categorized as accepted manuscripts and could be considered for publication in this IOP series. The locus of research interest varied from issues, practices, innovations, policies, and action plans of sustainability-led topics on land, waters, coastal and marine waters, air, forest, river basin, waste, land use, planning and community development. The cases are also widely distributed from across Indonesia with some of them are scoped within the Asia-Pacific, providing a rich of case studies and policy learning that is useful for knowledge development on sustainability issues.

In this opportunity, we would like to convey our gratitude and appreciation to all reviewers for their commitment to invest their time and expertise in making this proceeding realized and be able to be published. We are also grateful to all the committee members for the continued works from the beginning to the end of the ICEM conference.
