Saltwater intrusion poses severe threats to rice farming in Vietnam. Farmers can adapt by producing other crops or switching to other production models. This study evaluates the impact of implementing different saltwater-intrusion-adaptation strategies on farmers' livelihoods by applying propensity score matching to cross-sectional survey data for 414 farmers in the Central Coastal region of Vietnam. We consider both economic and social indicators and find that there is considerable heterogeneity in the outcomes. With the exception of switching to new rice varieties, all adaptation strategies considered in the study significantly increase saline-land productivity, mainly as a result of higher revenues. Moreover, for these strategies, food security is found to be significantly higher, whereas life satisfaction is only higher for those farm households that cultivate vegetables, shrimp, or lotus-fish. Adopting new rice varieties is found to significantly decrease saline-land productivity, whereas the social impacts are not significant. [ABSTRACT FROM AUTHOR]

Agroecology is receiving increasing attention and recognition as a concept for transitions to more sustainable agricultural and food systems. There is however a lack of characterization of agroecology in agricultural and food systems, while integrated and holistic measurements of their sustainability are scarce. Community Supported Agriculture (CSA) is considered to be a system explicitly based on agroecological principles and practices which shows potential in the face of the sustainability challenges in agriculture and food systems, but its link with agroecology and its holistic sustainability performance have remained understudied. Therefore, we applied the Tool for Agroecology Performance Evaluation (TAPE) to 24 Community Supported Agriculture farms in the Flanders region of Belgium in order to characterize agroecology and to assess their multidimensional sustainability performance. Our results show that Community Supported Agriculture farms can be characterized as advanced agroecological systems, highlighted by their high to very high performance on many of the elements of agroecology. Moreover, our results show positive outcomes on several sustainability criteria across environmental, social and economic dimensions such as soil health, presence of natural vegetation and pollinators and ecologicalmanagement of pests and diseases, as well as dietary diversity and profitability criteria like gross value, added value and net revenue. The integration and role of animals in these agroecosystems and the importance of - and dependence on - labor are however identified as two critical aspects regarding the agroecological transitions and sustainability of Community Supported Agriculture. Our findings emphasize the exemplary role Community Supported Agriculture could play in broader agroecological transitions, which, coupled with their high performance on several sustainability criteria, highlight the potential contribution of Community Supported Agriculture, and by extension of agroecology itself, to more sustainable agricultural and food systems in Flanders and beyond.

Globally irrigation subsidies are utilized to boost modernization and increase irrigation efficiency. This paper examines the effects of the irrigation subsidy programme in Chile by reviewing 32 years of allocations and exploring the drivers and consequences of the subsidy programme with a clear market approach based on competition and a state risk-free strategy. Our analysis reveals that, despite the flexibility in targeting, the results indicate an uneven allocation to smallholders' detriment, a state inability to identify farmers' needs, market concentration and a bias towards agricultural expansion. As long as the programme remains unaltered, it will threaten agriculture and water resources' sustainability. [ABSTRACT FROM AUTHOR]
