Households living in the close vicinity of shoreline are constantly threatened by various climate change impacts. Community awareness towards climate change is a subject of considerable study as adequate knowledge is a preliminary step for adaptation decision making. An important question is how coastal communities perceive climatic variation, sea level rise and coastal hazard impacts and the socio-economic factors that affect their level of awareness. Thus, this research measures the level of awareness and the factors influencing it based on a household survey (n = 1016) that was conducted 10 critically eroded coastal areas in Selangor. Descriptive statistical analysis reveals that more than half of the households have high level of awareness about climatic variation and sea level, however, there is moderate awareness about the coastal hazard impacts such as human causalities and disease transmission. Even though households are more aware of direct coastal hazard impact such as damages to properties and disruption of daily activities. An independent sample T test indicates that respondents who are male, at working age, educated, involve in natural resource dependent occupations, and had prior exposure to extreme coastal hazards have higher levels of awareness. Research indicated about 55% of all sampled households reflected awareness of climate change, 60% households were aware of sea level rise and 47% households were aware of coastal hazard impact. This study recommends that households in Selangor coast need capacity building and climate change awareness initiatives which would assist household to build adaptive capacity, increase resilience and reduce vulnerability to climate change., (Copyright © 2022 Elsevier Ltd.

The climate change effect has received a crucial concern from global policymakers as well as academic researchers. The climate change effect is a real-world issue threatening the existence of species and human beings, thus causing the economic vulnerability. Apart from policymakers, academic researchers are showing their concern on the effect of climate change on economic and socioeconomic vulnerability through publishing research articles in the recent decade. In light of the revolution of research articles, this study applied a bibliometric analysis on the academic research articles to explore the publication trends, themes, impacts, and potential scopes for further studies. Both the Scopus and the Web of Science online databases were used to search for journal articles linked to climate change effects and economic vulnerability. The final data of 229 journal articles were analyzed using bibliometric and visualization tools "Biblioshiny" and "VOSViewer." The findings unveiled an uprising trend in publications and posited several themes, mainly exposure, sensitivity, drought, and flood by means of climate change effects that affect economic vulnerability. Based on the findings and review of literature, several research gaps were identified and offered opportunities for further studies. The policymakers can attribute attention to encouraging more research in several areas in addition to agriculture and coastal regions., (© 2022.

Studies reveal that climate change (CC) has higher negative impacts on agricultural production than positive impacts. Therefore, this article attempts to explore the impacts of CC on oil palm production in Malaysia and provides mitigation and adaptation strategies towards reducing such impacts. The multiple regression analysis is applied to assess the impacts of CC on oil palm production by using time series data in the period of 1980 to 2010. A negative and significant relationship is found between annual average temperature and oil palm production. If temperature rises by 1 °C, 2 °C, 3 °C, and 4 °C, production of oil palm can decrease from a range of 10 to 41%. This article has also found a negative impact of sea level rise (SLR) on oil palm production. Findings reveal that if areas under oil palm production decrease by 2%, 4%, and 8% due to SLR of 0.5, 1, and 2 m, oil palm production can decrease by 1.98%, 3.96%, and 7.92%, respectively, indicating that CC has a significant impact on the reduction of oil palm production in Malaysia, ultimately affecting the sustainability of oil palm sector in Malaysia. Finally, this study suggests to practice appropriate mitigation and adaptation strategies, including promotion and development of climate resilient varieties, soil and water conservation, afforestation, insurance and other risk transfer mechanisms, emission reduction technology, protection of coastal flooding for reducing the impacts of CC on oil palm production.

This study empirically investigates the nexus among energy use, agricultural land expansion, deforestation, and carbon dioxide (CO2) emissions in Malaysia. Time series data from 1990 to 2019 were utilized using the bounds testing (ARDL) approach followed by the Dynamic Ordinary Least Squares (DOLS) method. The DOLS estimate findings show that the energy usage coefficient is positive and significant with CO2 emissions, indicating a 1% increase in energy consumption is related to a 0.91% rise in CO2 emissions. In addition, the coefficient of agricultural land is positive, which indicates that agricultural land expansion by 1% is associated with an increase in CO2 emissions by 0.84% in the long run. Furthermore, the forested area coefficient is negative, which means that decreasing 1% of the wooded area (i.e., deforestation) has a long-term effect of 5.41% increased CO2 emissions. Moreover, the pairwise Granger causality test results show bidirectional causality between deforestation and energy use; and unidirectional causality from energy use to CO2 emissions, agricultural land expansion to CO2 emissions, deforestation to CO2 emissions, agricultural land expansion to energy use, and deforestation to agricultural land expansion in Malaysia. The empirical findings reveal that increased energy use, agricultural land expansion, and deforestation have a negative impact on environmental quality in Malaysia. Thus, the effective implementation of policy measures to promote renewable energy, climate-smart agriculture, and sustainable management of forest ecosystems could be useful for reducing environmental degradation in Malaysia.

Climate change is having a profound impact on most coastal regions around the world. Sea Level Rise (SLR) has exposed the coastal regions to various threats, such as inundation and erosion, which consequently influence the coastal environments. The main objective of this study is to assess the coastal vulnerability index (CVI) of the Pahang coast. This CVI comprises six variables, i.e. coastal geomorphology, coastal slope, rate of erosion and accretion, mean significant wave height, mean tidal range and rate of sea level rise. The vulnerability levels for 18 management units along the Cherating-Pekan coast are classified into five vulnerability rankings: very low, low, moderate, high and very high, based on the rating values of the above mentioned parameters. The findings indicated that two areas, namely Tjg Payang - Sg Balok and Cheruk Paloh - Kuala Pahang were categorized as high vulnerability level with 97.22% and 91.67% respectively. Meanwhile, 5.56% and 22.22% of the 87 km Cherating-Pekan coastline has low and very low vulnerability. Furthermore, the CVI values of 33.33% and 27.78% represent the high and moderate vulnerability category, respectively. Finally, the outcome of this study provides a comprehensive framework which can be used by researchers, decision makers and relevant authorities to formulate and implement mitigation and adaptation measures in an effort to address the impacts of climate change on coastal regions.
