“…Modernization infringes on flood-prone locations due to land scarcity in urban areas (Ayog et al 2005). Malaysia, with an average yearly rainfall of 2500 mm, is one of the countries with the highest precipitation in the world (Ng et al, 2022).…”

Logistical planning is essential to reducing disaster-related suffering. As aid is essential, it must be managed effectively to ensure that the impacted population receives accurate and timely assistance. Every year, from October to March, the Northeast Monsoon brings torrential rainfall to the east coast of Peninsular Malaysia, notably Terengganu, resulting in catastrophic floods. This situation presents a unique logistical challenge in the island area, where humanitarian supplies must be delivered well before the monsoon season starts since the islands will become inaccessible due to weather and sea conditions. This study explored measures and approaches implemented by the Department of Social Welfare Malaysia (DoSW), a government agency responsible for distributing aid to Pulau Redang, Terengganu, in preparation for the monsoon season. A qualitative inquiry methodology using a case study was used to complete this study by conducting interviews with key respondents from DoSW as well as Pulau Redang’s local communities. The results showed that information gathering, pre-positioned supplies, good coordination among logistics agencies and local community involvement are essential strategies to ensure that disaster-affected communities get the supplies they need quickly and efficiently, especially in remote island areas.

Global warming has significantly increased the frequency and intensity of extreme events, which have catastrophic consequences for ecosystems and humans. Despite efforts to assess the impact of climate change on the potential risk of Borneo, most research has focused on partial regions, considering short timescales and a limited number of temperature and precipitation extremes indices to quantify the expected climate risks. This study employed a new method of climate risk assessment of Borneo based on the combined changes in various climate parameters. It estimated 23 climate indices at all grid points covering Borneo for three overlapping sub‐periods (1951–1980, 1961–1990, 1991–2020). The modified Mann‐Kendall test was employed to identify grid points exhibiting significant increasing or decreasing trends of each index for each sub‐period. Finally, significant trends of 23 indices were integrated to estimate the potential climate risk indicator (RI) based on the combined changes in various climate parameters for each grid point and sub‐period. Temperature indices showed a clear warming trend across Borneo Island, particularly in the eastern regions, with absolute temperature indices showing an increase of 0.5°C–2.5°C in 1991–2020 compared to the reference period (1951–1980). However, extreme cold temperatures have become less prevalent over the study period. There is a shift from light consecutive rainfall days towards more heavy and short‐duration rainfall events. Therefore, there are indications of intensifying rainfall events over the island's southern half, counterbalanced by drying trends in the northern regions, especially Brunei. The spatial distribution of RI revealed an overall 184% increase in climate risk on the island in recent years (1991–2020) compared to the reference period. The highest rise in RI was in the central east of the island, mostly due to significant increases in rainfall and temperature indices. The findings can inform adaptation initiatives to manage escalating heat and flood risks while guiding additional research to explain further the complex climatic changes occurring in this ecologically and socially vital region.
