Strategic delta planning focuses on strategic, long-term choices to stimulate sustainable development in deltas. Strategic delta plans outline a long-term vision to be embedded into the plans and activities of government agencies and semi-public actors at multiple levels. This implies a form of coordinated, yet decentralized, implementation. Although, its importance is widely acknowledged, there are few analytical approaches to assess the feasibility and possible bottlenecks of such implementation processes. This article applies a motivation and ability (MOTA) framework to assess the implementation feasibility of the Mekong Delta Plan in Ben Tre province, Vietnam. The results reveal diverging motivations and a perceived lack of ability among government actors at local and regional level. When not wellmanaged, this could hamper the translation of the strategic goals and visions into local and regional actions. This suggests the usefulness of the MOTA framework as a tool to help manage implementation processes for strategic delta planning.
Sustainable livelihood development is an ongoing challenge worldwide, and has regained importance due to threats of water shortages and climate change. To cope with changing climatic, demographic and market conditions in Vietnam's Mekong Delta (VMD) an agricultural transformation process has been suggested in the recent Mekong Delta Plan. This agricultural transformation process requires the implementation of alternative livelihood models. The majority of current agricultural livelihood models in the VMD have been introduced by the government in a top-down manner. In this study, we applied a bottom-up approach to understand the motivations and abilities of local farmers to adopt alternative livelihood models. It is based on the MOTA methodological framework, which is further tested with the use of multivariate analyses. The study was conducted in Ben Tre coastal province. Results showed that farmers' motivations and abilities to apply alternative models vary substantially among different groups, driven by their perceptions on triggers and opportunities. Acknowledging this diversity is essential to the development of agricultural transformation plans. Furthermore, based on the analysis, a projection of the precise support that communities need to supplement their knowledge, skills and financial capacities, as well as interventions to reduce the risks of new livelihood models, is given.
The choice for a biomaterial is partly based on the outcome of (cyto)toxicity assays. The rationales behind the selection of certain parameters, such as cell lines, controls, and animals, were evaluated using a positive and a negative control, and one experimental sample designed to induce intermediate toxicity. Extraction and direct contact assays were performed using human epidermal keratinocytes and mouse fibroblasts and mouse epithelial cells. Cell survival was measured with the tetrazolium salt (MTT) reduction assay. In addition, local implantation studies were performed in mice and rats. The positive control induced a high degree of toxicity in all in vitro tests performed, indicating that the toxicity observed in the direct contact assay was due to in situ extraction of toxic components. In the direct contact assay the negative control tested on the mouse fibroblasts resulted in a significant reduction of cell survival. No decrease in cell survival was found using the experimental sample. Subcutaneous implantation studies in mice showed that the positive control material induced a severe degeneration in mice. However, in rats just minimal alterations were noted. The experimental material induced moderate responses only in mice. Our results indicate that the direct contact assay provides limited additional information on the cytotoxicity of materials if certain limitations are not taken into account. For the in vivo implantation assay mice were superior to rats in detecting local toxic responses.
The Vietnamese Mekong Delta (VMD) is one of the most examined deltas in the world given its dynamics, complexity, and vulnerability. In the past decades, the VMD has changed rapidly, especially the land use in relation with the socioeconomic development.National policy has profoundly influenced these changes and the changes have significantly affected local livelihoods. However, these changes are not well reported systematically. In this study, we investigate land-use changes based on institutional analyses across multiple scales, that is, from national, provincial, to local livelihood based on institutional and sustainability analysis. The results show a strong relationship between legal settings over the last 30 years on land use and livelihood transitions. In addition, the constraints of implementing national legal frameworks at provincial level in practice were identified including effects to local livelihoods. We offer some recommendations for sustainable livelihoods in the VMD, with a focus on increasing socioecological resilience.
