Effective water management plays an important role in socioeconomic development in the Vietnamese Mekong Delta (VMD). The impacts of climate change and human activities (that is, domestic consumption and industrial and agricultural activities) vary in different subregions of the delta. In order to provide intersectoral data for determining the significantly impacted subregions of the VMD, the present study simulated interactions between local climatic patterns, human activities, and water resources using a system dynamics modeling (SDM) approach with each subregion as an agent of the developed model. The average rainfall and temperature of 121 subregions in the VMD were collected during 1982–2012, and the future changes of climate by provinces were based on the Representative Concentration Pathways (RCP) scenarios (RCP4.5 and RCP8.5) by the end of 21st century. The assessment was based on the levels of impact of various factors, including (1) water consumption, (2) differences between evapotranspiration and rainfall, and (3) spatial distribution of salinity intrusion over the delta scale. In the coastal areas, as well as the central and upstream areas, water resources were projected to be affected by environmental changes, whereas the former, characterized by the lack of surface freshwater, would be affected at a greater scale during the dry season. Besides, the sea level rise would lead to an increase in negative impacts in the eastern coastal areas, suggesting that water-saving techniques should be applied not only for agriculture, but also for industry and domestic water consumption during the dry season. In addition, the south subregions (that is, the western subregions of the Hau River except for An Giang) were likely to be flooded due to the simulated high rainfall and seasonal rises of sea level during the wet season. Therefore, the alternative forms of settlement and livelihood should be considered toward balance management with changing delta dynamics.

Critical Approach

This paper aims to understand how T-learning helps communities achieve better sustainability outcomes. On the basis of an intensive literature review and field research conducted in the Mekong Delta of Vietnam, the paper proposes a substantial linkage between T-learning and sustainability. It first outlines the environmental changes in Vietnam’s Mekong Delta, which appear to serve as “disorienting dilemmas” that force local people to learn and gradually shift their farming practices to align with a climate-resilient development. The paper relies on the outcomes of household surveys, field observations and focus group discussions to explore the impacts of T-learning on building adaptive capacity and sustainability transition in two community-based projects in Can Tho City and Ca Mau province in the Mekong Delta. Our findings reveal that T-learning enables experts and practitioners to introduce new ideas and accordingly mobilize local people to make changes without inciting doubt, dismay or concern. In an ideal T-learning approach, small-scale farmers learn from being under the supervision of experts in “field-based schools” that offer real-life experience and encourage learners to shift their livelihoods to eco-friendly agricultural practices. The paper sheds new light on how a critical approach to education for sustainable development through T-learning can be, under specific conditions, one strategy. It concludes that T-learning should be acknowledged as a potentially important part of the broader approach to climate-resilient development in vulnerable grassroots communities.

Disease outbreaks are considered the root of drug overuse and the main reason for crop failure in the Mekong Delta. Shrimp cooperatives appear to be a promising solution to struggle with the problem because the cooperative model has been proven to be successful in many sectors such as agriculture, industry, and services. This study examines the effectiveness of a shrimp cooperative in terms of information sharing and price reduction. We employ the propensity score matching method (PSM) to do the analysis, based on the data collected from 256 households in nine communes in the Phu Tan district, Ca Mau province for 2016 and 2017. The study finds limited benefits for farmers who participate in shrimp cooperatives. It further explains why many farmers withdrew after a time. Although shrimp cooperatives have a significant effect on exchanging information related to prohibited substances, shrimp cooperative participants withhold shrimp prices. In addition, we find that the probability of participating in a shrimp cooperative is higher in households with older age or more educated household heads. Moreover, if the farmer has undergone training, the probability of participating in a shrimp cooperative increases.
