    MINISTRY OF MINISTRY OF EDUCATION AND TRAINING PLANNING AND INVESTMENT DEVELOPMENT STRATEGY INSTITUTE NGUYEN LE VINH EVALUATING THE FACTORS THAT HAVE IMPACTS ON THE URBAN ECONOMIC GROWTH IN VIETNAM (TAKING HANOI CITY FOR EXAMPLE) Major: DEVELOPMENT ECONOMICS Code: 9 31 01 05 SUMMARY OF DOCTORAL THESIS HANOI - 2020 INTRODUCTION 1. Research purpose: Urban areas are the places that has high rate in economic growth, plays the role of being a center for trade, service, industry, culture, education, technology development, labor resource, new professions; a center for domestic and foreign commercial trade, attracting investment, developing external economic; plays the role in increasing national budget revenue and in protecting security and defense. Up to 2019, urban areas only account for 10% of the nation’s natural land, but urban economy contributes about 70% to the GDP annually. Thus, the urban economy plays a huge role in the national economy. In the period 2011-2019, with an average urbanization rate of 3.8%, Vietnam is a country with a high urbanization rate in Southeastern Asia, but the urbanization rate in 2019 only reached 35% while the world has achieved an average urbanization rate of 50% since 2007. The urbanization rate is one of the criteria that defines whether a country belongs to a group of developed or developing countries. Urbanization also contributes to economic growth. Therefore, promoting urbanization in Vietnam will remain an indispensable and objective trend in the coming time. However, urbanization in Vietnam are facing many challenges such as technical infrastructure system, urban planning, urban landscape architecture, environmental pollution ... this has a great impact on urban economic growth and national economic growth.

  • Trade in White-Rumped Shama Kittacincla Malabarica Demands Strong National and International Responses BOYD T
    FORKTAIL 34 (2018): 1–8 Trade in White-rumped Shama Kittacincla malabarica demands strong national and international responses BOYD T. C. LEUPEN, KANITHA KRISHNASAMY, CHRIS R. SHEPHERD, SERENE C. L. CHNG, DANIEL BERGIN, JAMES A. EATON, DAIRYSIA ANTHONY YUKIN, SHARON KOH PEI HUE, ADAM MILLER, K. ANNE-ISOLA NEKARIS, VINCENT NIJMAN, SALMAN SAABAN & MUHAMMED ALI IMRON Owing to its remarkable singing ability, the White-rumped Shama Kittacincla malabarica is a particularly popular species in the South-East Asian cage-bird trade. Despite domestic trade being regulated in six out of nine South-East Asian range states, demand continues to put a heavy strain on the region’s White-rumped Shama populations. The lack of international regulation further facilitates unsustainable trade in the species. We gathered data from seizure records, market surveys and online surveys to assess domestic and international trade dynamics and to suggest appropriate conservation responses to both. Combined data from surveys across Indonesia, Malaysia, Singapore, Thailand and Vietnam, carried out between 2007 and 2018, found a total of 8,271 White-rumped Shama for sale openly in local bird markets. Another 917 were found for sale online in six snapshot internet trade studies in Indonesia, Malaysia and Thailand between 2016 and 2018. In addition, 432 seizures were recorded between 2008 and 2018, involving 15,480 birds; significantly, 291 of these occurred between January 2014 and June 2018. Of all recorded seizure incidents, 12% involved international trade and accounted for 67% (10,376) of all White-rumped Shama seized. Because most seizure records are incomplete, the true figure is likely to be much higher.

However, the environmental degradation that has accompanied urban development has raised considerable concern from the public in recent years. This research investigates the effects of urban development on urban sprawl, urban heat island (UHI), and metropolitan weather phenomena that are related to the quality of urban life in the period from 1999–2016. To achieve these objectives, remote sensing technologies were applied to satellite images at three time points (i.e., 1999, 2009, and 2016) that were associated with the meteorological dataset from ground-based stations. The spatial distribution evolution was examined for the land use/land cover changes while using the normalized difference vegetation index (NDVI) and normalized difference built-up index (NDBI). The increasing impact of urban sprawl on UHI intensity is determined based on the land surface temperature (LST) in multi-temporal forms. Increasing urbanization with the development of gradual outward and northward expansion from the city centre intensified the correlation analysis shows that the UHI.

  • Characterizing Rice Residue Burning and Associated
    ABSTRACT Title of dissertation: CHARACTERIZING RICE RESIDUE BURNING AND ASSOCIATED EMISSIONS IN VIETNAM USING A REMOTE SENSING AND FIELD- BASED APPROACH Kristofer Lasko, Doctor of Philosophy, 2018 Dissertation directed by: Christopher Justice, Chair and Professor, Department of Geographical Sciences Agricultural residue burning, practiced in croplands throughout the world, adversely impacts public health and regional air quality. Monitoring and quantifying agricultural residue burning with remote sensing alone is difficult due to lack of field data, hazy conditions obstructing satellite remote sensing imagery, small field sizes, and active field management. This dissertation highlights the uncertainties, discrepancies, and underestimation of agricultural residue burning emissions in a small-holder agriculturalist region, while also developing methods for improved bottom-up quantification of residue burning and associated emissions impacts, by employing a field and remote sensing- based approach. The underestimation in biomass burning emissions from rice residue, the fibrous plant material left in the field after harvest and subjected to burning, represents the starting point for this research, which is conducted in a small-holder agricultural landscape of Vietnam. This dissertation quantifies improved bottom-up air pollution emissions estimates through refinements to each component of the fine-particulate matter emissions equation, including the use of synthetic aperture radar timeseries to explore rice land area variation between different datasets and for date of burn estimates, development of a new field method to estimate both rice straw and stubble biomass, and also improvements to emissions quantification through the use of burning practice specific emission factors and combustion factors. Moreover, the relative contribution of residue burning emissions to combustion sources was quantified, demonstrating emissions are higher than previously estimated, increasing the importance for mitigation.

    Appendix 1 JICA’s Major Activities Appendix 1 JICA’s Major Activities We have selected JICA’s major activities in the area of urban and regional development. A definition of “Urban and Regional Development” has not been made clear as part of JICA’s past cooperation (technical cooperation, development studies), and so here we provide those cases that would appear to conform to the definition contained herein. Regarding the relationship between the activities given here and the Mid-term Objectives given in the Chapter 2, most of the activities here correspond to Mid-term Objectives 1- 1, and 2-1, and we therefore deem it unnecessary to list these numbers. Also, the larger portion of the items here contain a range of various factors, however listing all of these would make it difficult to determine the characteristics of the cooperation, and we therefore select only those factors that are distinctive, and simply provide numbers for the Mid-term Objectives. Because they are past activities, Mid-term Objective numbers are not given where the distinctive characteristics cannot be determined.

Vulnerability and resilience on the streets: interrogating intersectionality among Southeast Asia’s street vendors Sarah Turner, Ammar Adenwala and Celia Zuberec INTRODUCTION Street vending is a key form of urban informality that provides livelihood oppor- tunities for millions of urban residents in the Global South, as well as for lesser numbers in the Global North (Recio and Gomez, 2013; Yotsumoto, 2013; Truong, 2018). Scholars working with street vendors in Global South locales have empha- sized the livelihood insecurity and poor working conditions that many vendors face. Additionally, scholars frequently highlight the exclusion of street vendors from spe- cific urban spaces, as states position vendors as “out of place”, hence marginalizing them even further (Yatmo, 2008). Local authorities often consider street vendors as incompatible with neoliberal visions of modernized and orderly urban environments, blaming vendors for producing unsanitary conditions and traffic congestion (Cross, 2000; Bhowmik, 2005). While city authorities strive for “new spatialities and tempo- ralities” (Sassen, 2000: 215), vendors, especially those trading itinerantly, are repeat- edly considered to be a form of slow mobility, an illegitimate form in need of being restricted or eliminated so that modern, legitimate mobilities, especially motorbikes and cars, can be encouraged and move quickly and freely. As a consequence, street vendors frequently face harassment from police and municipal workers who may forbid them from vending in a particular location, fine them or confiscate their goods. Nonetheless, in recent years, scholars have complicated the dominant narrative of street vending as primarily an informal livelihood pursued by marginalized populations for subsistence earnings. This contemporary research has highlighted that cities in the Global South can be home to an important diversity of street vendors.

  • Introduction* the Existence of the Protocol for World
    *Introduction* The existence of The Protocol for World Peace: A Prototype rests on the assumption that the secret to world peace is a discoverable pattern of ideas, and that this pattern is concealed, in whole or in part, in the written texts and vocalized or signed methods of communication presently in use throughout the world. The words of this process themselves become data for the purpose of analysis; and it follows that since the conceived data array is known to be (because on-going) of an infinite mass, the analytic methods to be followed must necessarily involve some form of programmable computerization. My part in all this has been to establish the initial sequence of events having to do with the collection of the data itself setting parameters for the collection in time and space and determining the nature of its authorship—everything except designing the programs suitable for its execution. Consequently: 1. The existence was postulated of a permanently progressive and fundamental change in organizational conceptualization, after which it became impossible to return to a world dominated by horse, wagon and sail, and which for want of a better term could be defined by the single term, Modernity. 2. The spatial components of this change were the 20th century (measured in time from 1901-2000; and a 19th century whose data collection time would stretch back to about 1680. This would be necessary because it was further thought that a. the entirety of Modernity must embrace the whole of the Industrial Revolution, in its mechanical as well as technological and digital phases; b.
