Solar energy policies in southeast Asia towards low carbon emission: A review.

ABSTRACT: Globally, countries are developing policies and encouraging the implementation of sustainable energy resources to reduce the harmful effects of fossil fuels on the environment and energy-related CO₂ emissions. In 2019, global energy-related CO₂ emissions increased by 1.8% to a new high of 33.3 Gt CO₂, owing to the increasing energy consumption. The CO₂ emissions are significantly increasing due to continuing increase of Southeast Asian countries. Energy utilization contributes to CO₂ emissions on earth because the energy sector produces 32,553.48 MtCO₂ of CO_2, or about 73% of total CO₂ emissions (WRI, 2019). The power sector alone accounted for approximately two-thirds of the emissions rise, indirectly warming the climate system, earth's temperature, and sea level. As a result, several governments have enacted policies to increase solar energy's share of the energy mix to minimize dependence on fossil fuels and environmental devastation. Therefore, this review paper presents a survey of solar energy policies implemented in Southeast Asian countries, specifically Malaysia, and assesses effective existing solar energy strategies in developed countries. Moreover, the implementation of Net Energy Metering needed for the advancing and widespread use of renewable energy technologies is also reviewed. Malaysia's existing solar energy policies have also been assessed and compared to the selected high-income nations. Lastly, limitations and key challenges of implementing large-scale applications of net energy metering policies are also presented.

Project description:BackgroundThe association between economic status and kidney disease is incompletely explored even in countries with higher economy (HE); the situation is complex in lower economies (LE) of South Asia and Southeast Asia (SA and SEA).MethodsFifteen countries of SA and SEA categorized as HE and LE, represented by the representatives of the national nephrology societies, participated in this questionnaire and interview-based assessment of the impact of economic status on renal care.ResultsAverage incidence and prevalence of end-stage kidney disease (ESKD) per million population (pmp) are 1.8 times and 3.3 times higher in HE. Hemodialysis is the main renal replacement therapy (RRT) (HE-68%, LE-63%). Funding of dialysis in HE is mainly by state (65%) or insurance bodies (30%); out of pocket expenses (OOPE) are high in LE (41%). Highest cost for hemodialysis is in Brunei and Singapore, and lowest in Myanmar and Nepal. Median number of dialysis machines/1000 ESKD population is 110 in HE and 53 in LE. Average number of machines/dialysis units in HE is 2.7 times higher than LE. The HE countries have 9 times more dialysis centers pmp (median HE-17, LE-02) and 16 times more nephrologist density (median HE-14.8 ppm, LE-0.94 ppm). Dialysis sessions >2/week is frequently followed in HE (84%) and <2/week in LE (64%). "On-demand" hemodialysis (<2 sessions/week) is prevalent in LE. Hemodialysis dropout rates at one year are lower in HE (12.3%; LE 53.4%), death being the major cause (HE-93.6%; LE-43.8%); renal transplants constitute 4% (Brunei) to 39% (Hong Kong) of the RRT in HE. ESKD burden is expected to increase >10% in all the HE countries except Taiwan, 10%-20% in the majority of LE countries.ConclusionEconomic disparity in SA and SEA is reflected by poor dialysis infrastructure and penetration, inadequate manpower, higher OOPE, higher dialysis dropout rates, and lesser renal transplantations in LE countries. Utility of RRT can be improved by state funding and better insurance coverage.

Project description:BackgroundAn increasing use of point of care diagnostic tests that exclude malaria, coupled with a declining malaria burden in many endemic countries, is highlighting the lack of ability of many health systems to manage other causes of febrile disease. A lack of knowledge of distribution of these pathogens, and a lack of screening and point-of-care diagnostics to identify them, prevents effective management of these generally treatable contributors to disease burden. While prospective data collection is vital, an untapped body of knowledge already exists in the published health literature.MethodsFocusing on the Mekong region of Southeast Asia, published data from 1986 to 2011 was screened to for frequency of isolation of pathogens implicated in aetiology of non-malarial febrile illness. Eligibility criteria included English-language peer-reviewed studies recording major pathogens for which specific management is likely to be warranted. Of 1,252 identified papers, 146 met inclusion criteria and were analyzed and data mapped.ResultsData tended to be clustered around specific areas where research institutions operate, and where resources to conduct studies are greater. The most frequently reported pathogen was dengue virus (n = 70), followed by Orientia tsutsugamushi and Rickettsia species (scrub typhus/murine typhus/spotted fever group n = 58), Leptospira spp. (n = 35), Salmonella enterica serovar Typhi and Paratyphi (enteric fever n = 24), Burkholderia pseudomallei (melioidosis n = 14), and Japanese encephalitis virus (n = 18). Wide tracts with very little published data on aetiology of fever are apparent.Discussion and conclusionsThis mapping demonstrates a very heterogeneous distribution of information on the causes of fever in the Mekong countries. Further directed data collection to address gaps in the evidence-base, and expansion to a global database of pathogen distribution, is readily achievable, and would help define wider priorities for research and development to improve syndromic management of fever, prioritize diagnostic development, and guide empirical therapy.
