The Future

<p>A new version of the UKCA chemistry-climate model with highly reactive volatile organic compounds (VOCs) is used to investigate the ozone (O<sub>3</sub>) responses in historical (2004-2014) and future (2045-2055) shared socio-economic pathways (SSPs) scenarios of CMIP6 AerChemMIP experiments. Significant increases in surface O<sub>3</sub> levels in South and East Asia are simulated in the new version compared with the standard UKCA model. The O<sub>3</sub> production and the O<sub>3</sub> burden averaged over the troposphere increase slightly by 6 % as a result of more highly reactive VOCs, but the O<sub>3</sub> lifetime is quite similar. Comparing the different SSP scenarios using this new model version we find the averaged surface O<sub>3</sub> concentrations are higher in the scenario with high emissions than for historical conditions. O<sub>3</sub> concentrations are much lower than historical O<sub>3</sub> concentrations when O<sub>3</sub> precursor concentrations are low. However, regional O<sub>3</sub> increases occur in East Asia in the future scenario with low emissions of short-lived climate forcers due to strong VOC limited regimes. Decreases in surface O<sub>3</sub> concentrations occur globally in the future scenario that has lower methane (CH<sub>4</sub>) concentrations. We construct O<sub>3</sub> and O<sub>3</sub> production isopleths. These both suggest that the threshold of NO<sub>x</sub>/VOCs shifting from NO<sub>x</sub> limited to VOC limited regimes is approximately 0.8. More areas become VOC limited in South Asia in all future scenarios, but there is little change for East Asia. The hydroxyl radical (OH) concentrations generally increase in regions with high O<sub>3</sub> precursor abundances in the future scenario, but the high OH levels are offset by lower CH<sub>4</sub> concentrations in the future low CH<sub>4</sub> scenario. We find that there are small changes in O<sub>3</sub> production efficiency in continental regions in all future scenarios. Relative O<sub>3</sub> burden changes between the future SSP and historical scenarios are larger in the troposphere than in the planetary boundary layer (PBL), illustrating that O<sub>3</sub> burdens are less sensitive in the PBL under emission and climate change. The O<sub>3</sub> lifetime in the troposphere decreases in all future scenarios as compared to the historical period. We find that the decreases in O<sub>3</sub> precursors and CH<sub>4</sub> concentrations play important roles in reducing O<sub>3</sub> burdens in the future.</p>

Asean Countries

The 1997–1998 financial crisis brought the issue of necessity to implement deep structural reforms to the agenda in South-East Asia countries. Domestic consumption encouragement, increase of cooperation between different countries' real sectors of economy and strengthening the role of the ASEAN countries in both anti-crisis arrangements and arriving at consensus on interaction with communication partners became focus areas. The detailed specification of measures assumed by particular countries of the region to mitigate crisis effects, stabilize economy and formulate a strategy of economic growth is presented in the article.

We examine the interrelationship among foreign aid, foreign direct investment (FDI) and economic growth in South-East Asia (SEA) and South Asia (SA) during 1980–2016. The findings from alternative empirical estimations suggest that while foreign aid is negatively associated with FDI as well as growth, FDI positively influences growth. Further, governmental financial assistance to private sector for domestic investment turns out to be important in all empirical estimations insofar as positively associated with FDI flows as well as growth. We, therefore, infer that low-income SEA and SA economies should focus on channelizing governmental financial assistance to private sector for domestic investment, macroeconomic stabilization, trade openness, and efficient utilization of aid flows, in order to attract, absorb and reap the benefits of complementing FDI flows and sustaining higher economic growth.

Financial Investment

In recent years, many South East Asian nations have shown strong economic growth coupled with success in attracting considerable direct foreign investment. In order to sustain the current and projected growth levels, many countries in South East Asia will need to focus on major investments for infrastructure development, especially in their power generation and distribution sectors. As highlighted by the current financial crises being experienced in several South East Asian nations, the future growth of this region will require much stronger support from the international financial institutions, which in turn will lead this region toward a greatly increased level of privatization. The establishment of contestable energy markets is a particularly good example of the type of developments required in these nations. In order to create a healthy climate for the massive financial investment needed for a truly liberalized energy market, a number of difficult political and social issues common to many of these rapidly developing economies must be resolved.
