Hunter-gatherers in southeast Asia: from prehistory to the present

Higham C

PMID: 24297219

Anatomically modern hunter-gatherers expanded from Africa into Southeast Asia at least 50,000 years ago, where they probably encountered and interacted with populations of Homo erectus and Homo floresiensis and the recently discovered Denisovans. Simulation studies suggest that these hunter-gatherers may well have followed a coastal route that ultimately led to the settlement of Sahul, while archaeology confirms that they also crossed significant seas and explored well into the interior. They also adapted to marked environmental changes that alternated between relatively cool and dry conditions and warmer, wetter interludes. During the former, the sea fell by up to 120 m below its present level, which opened up a vast low-lying area known as Sundaland. Three principal alignments can be identified: the first involved the occupation of rock shelters in upland regions, the second has identified settlement on broad riverine floodplains, and the last concentrated on the raised beaches formed from about five millennia ago when the sea level was elevated above its present position. This cultural sequence was dislocated about 4 kya when rice and millet farmers infiltrated the lowlands of Southeast Asia ultimately from the Yangtze River valley. It is suggested that this led to two forms of interaction. In the first, the indigenous hunter-gatherers integrated with intrusive Neolithic communities and, while losing their cultural identity, contributed their genes to the present population of Southeast Asia. In the second, hunter-gatherers withdrew to rainforest refugia and, through selective pressures inherent in such an environment, survived as the small-bodied, dark-skinned humans found to this day in the Philippines, Peninsular Malaysia and Thailand, and the Andaman Islands. Beyond the impact of expansive rice farmers in Melanesia and Australia, hunter-gatherers continued to dominate until they encountered European settlement.

PLoS One, 2014;9(1):e86782.

PMID: 24497978 DOI: 10.1371/journal.pone.0086782

Seagrass species in the tropics occur in multispecies meadows. How these meadows are maintained through species co-existence and what their ecological drivers may be has been an overarching question in seagrass biogeography. In this study, we quantify the spatial structure of four co-existing species and infer potential ecological processes from these structures.

Prehistoric human migration between Sundaland and South Asia was driven by sea-level rise

Kim HL, Li T, Kalsi N, Nguyen HTT, Shaw TA, Ang KC, et al.

Commun Biol, 2023 Feb 04;6(1):150.

PMID: 36739308 DOI: 10.1038/s42003-023-04510-0

Rapid sea-level rise between the Last Glacial Maximum (LGM) and the mid-Holocene transformed the Southeast Asian coastal landscape, but the impact on human demography remains unclear. Here, we create a paleogeographic map, focusing on sea-level changes during the period spanning the LGM to the present-day and infer the human population history in Southeast and South Asia using 763 high-coverage whole-genome sequencing datasets from 59 ethnic groups. We show that sea-level rise, in particular meltwater pulses 1 A (MWP1A, ~14,500-14,000 years ago) and 1B (MWP1B, ~11,500-11,000 years ago), reduced land area by over 50% since the LGM, resulting in segregation of local human populations. Following periods of rapid sea-level rises, population pressure drove the migration of Malaysian Negritos into South Asia. Integrated paleogeographic and population genomic analysis demonstrates the earliest documented instance of forced human migration driven by sea-level rise.

Fulltext Southeast Asian health system challenges and responses to the 'Andaman Sea refugee crisis': A qualitative study of health-sector perspectives from Indonesia, Malaysia, Myanmar, and Thailand

Legido-Quigley H, Leh Hoon Chuah F, Howard N

PLoS Med, 2020 11;17(11):e1003143.

PMID: 33170834 DOI: 10.1371/journal.pmed.1003143

BACKGROUND: Southeast Asian countries host signficant numbers of forcibly displaced people. This study was conducted to examine how health systems in Southeast Asia have responded to the health system challenges of forced migration and refugee-related health including the health needs of populations affected by forced displacement; the health systems-level barriers and facilitators in addressing these needs; and the implications of existing health policies relating to forcibly displaced and refugee populations. This study aims to fill in the gap in knowledge by analysing how health systems are organised in Southeast Asia to address the health needs of forcibly displaced people.

METHODS AND FINDINGS: We conducted 30 semistructured interviews with health policy-makers, health service providers, and other experts working in the United Nations (n = 6), ministries and public health (n = 5), international (n = 9) and national civil society (n = 7), and academia (n = 3) based in Indonesia (n = 6), Malaysia (n = 10), Myanmar (n = 6), and Thailand (n = 8). Data were analysed thematically using deductive and inductive coding. Interviewees described the cumulative nature of health risks at each migratory phase. Perceived barriers to addressing migrants' cumulative health needs were primarily financial, juridico-political, and sociocultural, whereas key facilitators were many health workers' humanitarian stance and positive national commitment to pursuing universal health coverage (UHC). Across all countries, financial constraints were identified as the main challenges in addressing the comprehensive health needs of refugees and asylum seekers. Participants recommended regional and multisectoral approaches led by national governments, recognising refugee and asylum-seeker contributions, and promoting inclusion and livelihoods. Main study limitations included that we were not able to include migrant voices or those professionals not already interested in migrants.

CONCLUSIONS: To our knowledge, this is one of the first qualitative studies to investigate the health concerns and barriers to access among migrants experiencing forced displacement, particularly refugees and asylum seekers, in Southeast Asia. Findings provide practical new insights with implications for informing policy and practice. Overall, sociopolitical inclusion of forcibly displaced populations remains difficult in these four countries despite their significant contributions to host-country economies.

Dental perspectives on the population history of Southeast Asia

Matsumura H, Hudson MJ

Am. J. Phys. Anthropol., 2005 Jun;127(2):182-209.

PMID: 15558609

This article uses metric and nonmetric dental data to test the "two-layer" or immigration hypothesis whereby Southeast Asia was initially occupied by an "Australo-Melanesian" population that later underwent substantial genetic admixture with East Asian immigrants associated with the spread of agriculture from the Neolithic period onwards. We examined teeth from 4,002 individuals comprising 42 prehistoric and historic samples from East Asia, Southeast Asia, Australia, and Melanesia. For the odontometric analysis, dental size proportions were compared using factor analysis and Q-mode correlation coefficients, and overall tooth size was also compared between population samples. Nonmetric population affinities were estimated by Smith's distances, using the frequencies of 16 tooth traits. The results of both the metric and nonmetric analyses demonstrate close affinities between recent Australo-Melanesian samples and samples representing early Southeast Asia, such as the Early to Middle Holocene series from Vietnam, Malaysia, and Flores. In contrast, the dental characteristics of most modern Southeast Asians exhibit a mixture of traits associated with East Asians and Australo-Melanesians, suggesting that these populations were genetically influenced by immigrants from East Asia. East Asian metric and/or nonmetric traits are also found in some prehistoric samples from Southeast Asia such as Ban Kao (Thailand), implying that immigration probably began in the early Neolithic. Much clearer influence of East Asian immigration was found in Early Metal Age Vietnamese and Sulawesi samples. Although the results of this study are consistent with the immigration hypothesis, analysis of additional Neolithic samples is needed to determine the exact timing of population dispersals into Southeast Asia.

PMID: 12317236

"This paper assesses the level and composition of contemporary Asian immigration to Australia and explores its processes and impacts. The final reversal of the White Australia Policy in the 1970s opened the door to substantial increases in Asian immigration, particularly from Vietnam, Malaysia, the Philippines, China, India and Hong Kong." Aspects considered include migrant categories, age, sex, and social and economic adaptation to Australia.

International labor migration and the family: some observations from Indonesia

Hugo G

Asian Pac Migr J, 1995;4(2-3):273-301.

PMID: 12320103

This article addresses two dimensions of the complex interrelationship between the family and international labor migration in Indonesia: the role of the family in influencing labor movements out of Indonesia; and the consequences of this movement on family well-being, structure, and functioning. Research on this topic in Indonesia is highly limited due mainly to the recency of large scale international labor migration, inadequate data collection systems, a high incidence of undocumented migration, and failure of available research to be sensitive to family related issues. Against a rapidly changing economic and social situation, two major overlapping systems of migration have developed. The official system is focused strongly on the Middle East (although other Asian destinations are increasing in significance) and is dominated by female migrants. The undocumented system is much larger in volume, is focused upon Malaysia, involves more males than females, and is becoming permanent in some cases. The role, status, and experiences of women migrants in relation to their families (decision making, networks, remittances) are discussed with recommendations for other areas needing further research attention.

Impacts of suspended sediment and metal pollution from mining activities on riverine fish population-a review

Affandi FA, Ishak MY

Environ Sci Pollut Res Int, 2019 Jun;26(17):16939-16951.

PMID: 31028621 DOI: 10.1007/s11356-019-05137-7

Mining activities are responsible for the elevated input levels of suspended sediment and hazardous metals into the riverine ecosystem. These have been shown to threaten the riverine fish populations and can even lead to localized population extinction. To date, research on the effects of mining activities on fish has been focused within metal contamination and bioaccumulation and its threat to human consumption, neglecting the effects of suspended sediment. This paper reviews the effects of suspended sediment and metal pollution on riverine ecosystem and fish population by examining the possibilities of genetic changes and population extinction. In addition, possible assessments and studies of the riverine fish population are discussed to cope with the risks from mining activities and fish population declines.

Fulltext Temporal changes in the abundance of Musca domestica Linn (Diptera: Muscidae) in poultry farms in Penang, Malaysia

Jin BL, Jaal Z

Trop Biomed, 2009 Aug;26(2):140-8.

PMID: 19901900 MyJurnal

Changes in the abundance of the house fly, Musca domestica, was studied for a period of one year in two poultry farms in Penang, Malaysia: one in Balik Pulau, located in Penang island, and the other in Juru, located on mainland Penang. The sampling of house flies were carried out from March 2007 to April 2008 using the Scudder grill, and the correlation with meteorological conditions particularly rainfall, relative humidity and temperature were observed. In Balik Pulau, the fly abundance showed an inverse relationship to relative humidity and total rainfall. However, no significant correlations were found between the abundance of flies and the above mentioned climatic factors. In contrast, the occurrence of flies in Juru showed strong correlation indices with relative humidity (r=0.803, p<0.05) and total rainfall (r=0.731, p<0.05). Temperature had no significant effect on the abundance of flies in both poultry farms due to imperceptible changes in monthly temperature.

Climate change and declining fertility rate in Malaysia: the possible connexions

Jegasothy R, Sengupta P, Dutta S, Jeganathan R

J Basic Clin Physiol Pharmacol, 2020 Dec 14;32(5):911-924.

PMID: 33580644 DOI: 10.1515/jbcpp-2020-0236

Climate change is an incessant global phenomenon and has turned contentious in the present century. Malaysia, a developing Asian country, has also undergone significant vicissitudes in climate, which has been projected with significant deviations in forthcoming decades. As per the available studies, climate changes may impact on the fertility, either via direct effects on the gonadal functions and neuroendocrine regulations or via several indirect effects on health, socioeconomic status, demeaning the quality of food and water. Malaysia is already observing a declining trend in the Total fertility rate (TFR) over the past few decades and is currently recorded below the replacement level of 2.1 which is insufficient to replace the present population. Moreover, climate changes reportedly play a role in the emergence and cessation of various infectious diseases. Besides its immediate effects, the long-term effects on health and fertility await to be unveiled. Despite the huge magnitude of the repercussion of climate changes in Malaysia, research that can explain the exact cause of the present reduction in fertility parameters in Malaysia or any measures to preserve the national population is surprisingly very scarce. Thus, the present review aims to elucidate the possible missing links by which climate changes are impairing fertility status in Malaysia.
