The purpose of this paper is to examine the extent of the trade integration of Thailand with the Mekong region in comparison with its trade integration with the other major partners (advanced ASEAN, China, India, Japan, and the USA).

The study adopts the gravity trade model as an analytical framework, for the period from the 1980s through the 2000s.

It is found that Thailand's trade integration with the Mekong region has remarkably grown from the 1980s to the 2000s, in the sense that Thailand's total trade with the Mekong region, which lies below the gravity‐model standard in the 1980s, exceeds the standard in the 1990s and the 2000s. However, it is also found that the intensity of Thailand's trade integration with the Mekong region is still behind that with advanced ASEAN even in the 2000s. It might come from the higher service‐link costs that prevent the Mekong region from being fully involved in the international production network.

The paper may be valuable to the policy makers and researchers in the Mekong region, since it contributes to reviewing the two‐decade progress of the regional cooperation of the Greater Mekong Subregion from such quantitative perspectives as trade integration.

Agricultural and food systems in the Mekong Region are undergoing transformations because of increasing engagement in international trade, alongside economic growth, dietary change and urbanisation. Food systems approaches are often used to understand these kinds of transformation processes, with particular strengths in linking social, economic and environmental dimensions of food at multiple scales. We argue that while the food systems approach strives to provide a comprehensive understanding of food production, consumption and environmental drivers, it is less well equipped to shed light on the role of actors, knowledge and power in transformation processes and on the divergent impacts and outcomes of these processes for different actors. We suggest that an approach that uses food systems as heuristics but complements it with attention to actors, knowledge and power improves our understanding of transformations such as those underway in the Mekong Region. The key transformations in the region include the emergence of regional food markets and vertically integrated supply chains that control increasing share of the market, increase in contract farming particularly in the peripheries of the region, replacement of crops cultivated for human consumption with corn grown for animal feed. These transformations are increasingly marginalising small-scale farmers, while at the same time, many other farmers increasingly pursue non-agricultural livelihoods. Food consumption is also changing, with integrated supply chains controlling substantial part of the mass market. Our analysis highlights that theoretical innovations grounded in political economy, agrarian change, development studies and rural livelihoods can help to increase theoretical depth of inquiries to accommodate the increasingly global dimensions of food. As a result, we map out a future research agenda to unpack the dynamic food system interactions and to unveil the social, economic and environmental impacts of these rapid transformations. We identify policy and managerial implications coupled with sustainable pathways for change.

In late 2015, the El Nĩno phenomenon induced Vietnam’s worst drought in 60 years, which lasted until mid-2016 and intensified the most expansive saline intrusion in 90 years. The combination of the two hazards resulted in a large-scale disaster, which has led 18 provinces of Vietnam, most of them from the Mekong Delta, to water shortage, insanitation, human and animal diseases, food emergency need and a considerable disruption in local communities’ livelihoods. These devastating effects raise the question of what makes local households vulnerable to drought and saline intrusion. The chapter argues that vulnerability to the natural disaster is not something resulted from external threats, but rather, is derived from the interplay between social structures residing deeply inside the socio-economic systems and agency’s conditions presenting at the household level. Social structures are rules and procedures that constrain and/or enable human actions in agricultural production, risk taking and adaptation. Agency refers to the capacities of disaster-affected households in the Vietnamese Mekong Delta who cultivated third rice crop and suffered heavily from the 2015–2016 disaster. In addition to households’ lack of planning and coping capacities, the constitution of vulnerability to drought and saline intrusion can be attributed to the interaction between farmers’ choice of extra rice crops and the state’s policies and directions in agricultural and irrigation development since 1990s to date.

The Monsoon Asian region has a much wider rainfall distribution than other regions of the world. The countries in this region are characterized mostly by floods and typhoons, which result from the interplay among the ocean, the atmosphere, and the land. Thus, many factors affect the strength of the rainfall, including sea surface temperatures in the Indian and Pacific Oceans, variations in solar output, land snow cover and soil moisture over the Asian continent, and the position and strength of prevailing winds. The links between these factors and monsoons appear to wax and wane over time, and the observational record is too short to explain this longer-term variability. Precipitation and surface wind maps of Asia during the summer months of June to August show the average spatial patterns of monsoon circulation and moisture.

This paper aims to focus on scrutinizing the economics of greenhouse gas (GHG) emissions in Vietnam's rice production sector.

Using surveyed data from household rice producers, the smallest available production scale, the author delves into the economics of GHG emissions, constructs a data-driven bottom-up marginal abatement cost curve for Vietnam’s rice production, and evaluates the impacts of carbon pricing on production outputs and GHG emissions.

The author’s estimates reveal that the average profit earned per tonne of GHG emissions is $240/tCO2. Notably, the profit earning per tonne of GHG emissions varies substantially across producers, indicating significant opportunities for improvement among low-efficiency producers. The analysis suggests that a reasonable carbon price would yield a modest impact on the national rice output. The quantitative analysis also reaffirms that the primary driver of GHG emissions in Vietnam’s rice production stems from non-energy inputs and industrial processes rather than the utilisation of energy inputs, emphasizing the importance of improving cultivation techniques.

Drought and salinity intrusion aggravated by climate change threaten agricultural livelihoods in Viet Nan's Mekong Delta. In response, authorities have built water management infrastructure for irrigation and salinity protection. This study assessed the impact of one such project, the Ba Lai dam in Ben Tre province, on the livelihoods of aquaculture farmers.

This study uses the Sustainable Livelihoods Framework to assess the impact of the Ba Lai dam on the livelihood capitals of 18 farming households in four communes, located both upstream and downstream of the dam.

The authors find that, apart from some positive effects, the dam has also brought negative environmental consequences, such as increased water pollution. The authors also find that farmers have responded to the changes by adapting their livelihood practices.

The samples were relatively small, encompassing four communes in Ben Tre province. On the other hand, this case study is instructive to the many ongoing infrastructure projects in the Vietnamese Mekong Delta.

The project have caused an increase in water-related social conflict.

The case of the Ba Lai dam provides a cautionary example for infrastructure-based water management plans, both in Viet Nam and more broadly. The study suggests the need to strengthen community participation and prioritize impacts of farmers' capital assets when constructing water management infrastructure for climate change adaptation.

The purpose of this paper is to analyse social and environmental sustainability considerations developed in Lao People's Democratic Republic (Lao PDR) and to identify problems and challenges related to sustainable hydropower planning and development.

The paper is leaning on empirical analysis based on analysing primary and secondary data and information; official government documents and relevant literature, a series of workshops of the Future Resource and Economy Policies in Laos till 2020 Project (FREPLA2020), and interviews with government officials and experts.

To achieve its socio‐economic objectives, Lao PDR needs to manage its hydropower development to ensure environmental and social sustainability through developing of the legal, institutional and regulatory environment and strengthening of the institutional capacity of the sector, improving knowledge and data management, and developing institutional coordination across the government agencies.

The paper suggests that the Lao government assesses strategically the hydropower development options, prepares capacity building plans, develops risk assessment and management, and learns from past hydropower developments.

The paper recommends using hydropower development generated revenues to poverty reduction activities and to strengthen participatory approaches.

The paper can act as a discussion awakener, to help and give some guidance to decision makers and actors in the hydropower sector to integrate sustainable development considerations into hydropower development and planning.

This study aims to evaluate the impact of climate change on some specific areas of agricultural production in Quang Nam Province, including assessing the possibility of losing agricultural land owing to sea level rise; assessing the impact on rice productivity; and, assessing the impact on crop water demand.

This study used the method of collecting and processing statistics data; method of analysis, comparison and evaluation; method of geographic information system; method of using mathematical model; and method of professional solution, to assess the impacts of climate change.

Evaluation results in Quang Nam Province show that, by the end of the 21st century, winter–spring rice productivity may decrease by 33%, while summer–autumn rice productivity may decrease by 49%. Under representative concentration pathway (RCP) 4.5 scenario, water demand increases by 31.1% compared to the baseline period, of which the winter–spring crop increases by 28.4%, and the summer–autumn crop increased by 34.3%. Under RCP 8.5 scenario, water demand increases by 54.1% compared to the baseline period, of which the winter–spring crop increases by 46.7%, and the summer–autumn crop increased by 63.1%. The area of agricultural land likely to be inundated by sea level rise at 50 cm is 418.32 ha, and at 80 cm, it is 637.07 ha.

To propose adaptation solution to avoid the impacts of climate change on agriculture, it is necessary to consider about the impact on losing land for agriculture, the impact on rice productivity, assess the impact on crop water demand and other. The result of this assessment is useful for policymakers for forming the agriculture development plan.
