Abstract: Vietnam’s forests have experienced a notable transformation over the past 20 years from net deforestation to reforestation and expanding forests. Continued reforestation that aims to achieve further economic and environmental benefits remains a national priority and strategy. We explore the current status of plantation forests and highlight possible means to facilitate their expansion in the uplands of Vietnam. We employ mixed method triangulation to empirically explore plantation forests and their economic role in household livelihood, to quantify trade-offs between plantation forests and shifting cultivation, and to assess the constraints on plantation forest expansion in Nghe An province, north-central Vietnam. Results show that forest in the study area expanded by 406,000 ha (71.1%) between 1990 and 2016. Plantation forests increased by nearly 500% (from 32,000 ha to 190,000 ha), while natural forests expanded by 48.1% (from 538,000 ha to 797,000 ha). Plantation forests contributed an average of 35.1 percent of total household income in wealthier households and 27.9 percent of income in poor households. Switching from shifting cultivation to plantation forests would increase total household income and average carbon stock but decrease food provision. Total Economic Value would be higher for plantation forest scenarios if increased carbon stocks in plantations can be monetized. This carbon income might drive conversion of shifting cultivation to plantation forests. Constraints on further expansion of plantation forest are low external cooperation, education, market stability, and agroforestry extension services. Our empirical results inform national plantation forest development, sustainable upland livelihood development, and climate change mitigation programs to ultimately facilitate forest transition and improve the resilience and sustainability of socio-ecological systems.

Abstract: Understanding household's decision making in agricultural production to natural hazards is significant for policymakers and extension organizations in supporting farmers to optimize adaptive strategies, there are, however, still limited empirical researches that emphasize the determinants affecting the choice of measures in the process of adaptation. This paper explores the decision-making process of rural households in adapting to flash floods and landslides (FF&LS) by conducting a household survey on 405 purposively selected households in Yen Bai province, one of the poorest mountainous regions in Vietnam. Based on the multi-portfolio framework, the study assumes that farmers have multiple choice of adaptation strategies simultaneously and these adaptation measures are correlative. Multivariate Probit models were used to figure out the household decision making process in adapting to FF&LS. Survey results showed that changing cropping patterns, crop variegation, ersifying types of crop varieties, as well as managing and implementing crop protection (soil and plant) are the primary adaptation measures applied by local farmers. Furthermore, lack of money, inadequate support from local government, shortage of machinery and technical equipment, as well as insufficient knowledge about FF&LS were listed as major constraints in the study area. The MVP analysis indicated that all farmers' perception, socio-economic, farming features, and institutional conditions strongly influence the farmers' adaptation decisions regarding FF&LS. Future policies may therefore need to consider these major contributing factors with appropriate interventions to facilitate suitable adaptations for local farmers.

Abstract: This paper evaluates the potential effects of future commercial shipping through the Northern Sea Route and Northwest Passage on the spread of nonindigenous species (NIS) between Europe, the United States, and the Asia-Pacific region. We modeled NIS spread risk as a function of two factors: NIS introduction and NIS establishment. The change in risk of NIS introduction from one region to another is based on the expected commodity trade flow between the two regions given Arctic shipping routes. The risk of NIS establishment is based on current marine climate similarities between regions and projected 2030 terrestrial climate similarities. Results indicate that the United States, China, and Japan are at greatest risk for increased terrestrial and marine NIS spread to and from one another given their relatively high levels of trading activity and terrestrial and marine climate similarities. While increased trade between European and Asia-Pacific countries is expected in the future, only Japan has terrestrial climate similar enough to that of European countries to be considered a substantial terrestrial NIS spread risk, while China has the potential to increase the risk of marine NIS species spread in Europe.
