Tea (Camellia sinensis L.), as one of the most important cash crops in China, plays an important role in increasing farmers' incomes and guaranteeing a high quality of life. Tea production has been greatly influenced by both climate change and economic development in China. However, without a scientific understanding of the interaction mechanism of climate change and the impetus from rapid economic development on tea production practices in China, it is difficult to take adaptive actions to meet the climate change challenges for the tea industry. In this paper, we firstly assessed the potential impacts of climate change on tea climate suitability by empirical formula calculation using meteorological data; then, the effects from the additional climatic stress due to warming on tea production were detected with the annual statistical tea yield record on a municipal level. The contribution of socioeconomic development to the tea industry was evaluated with the comparison of the movement of China's national economy's and tea industry's gravity center during the period of 1987–2017. Finally, a conceptual adaptation framework was built to demonstrate the interaction mechanisms between climate change, tea production, and the economic development. The results showed that there was a negative impact of climate change on tea production in mainland China, with the percentage of high tea climate suitability (>0.9) areas dropping by 45% to 32%, while opportunities of enlarging the tea cultivating area emerged in the north tea production region where the tea climate suitability increased. We found that the tea planting area expanded northwards from 33° N in 1987 to 35° N in 2017 to take advantage of the favorable climatic resources due to warming, and tea planting decreased at an altitude of 100–400 m while increasing to higher altitude of 400–2000 m to avoid hot temperature damage and seek the optimum environment in high mountainous areas for tea production. In addition, the tea production moved westward along the longitude, decreasing obviously at 117–121° E while increasing significantly at 98–104° E and 107–110° E. Meanwhile, the tea production gravity center showed a westward movement consistent with the national economic gravity center moving trend, which means that tea industry development was driven by multiple socioeconomic factors and climatic forcings. A conceptual framework was built in this paper, aiming to show a robust adaptation mechanism for the tea system to maximize the benefits and minimize the damages from the altered climatic resources under rapid economic development in mainland China. The results in this study would help deepen the understanding of the adaptation process and practices for tea production in mainland China. [ABSTRACT FROM AUTHOR]

It has been projected that the single greatest impact of environmental changes will be on human migration and displacement. Migration has been extensively discussed and documented as an adaptation strategy in response to environmental changes, and more recently, to climate change. However, forced relocation will lead to the displacement of people, and although much has been written about it, very little has been documented from the Pacific Islands perspective, especially by communities that were forced to relocate as a result of colonialism and those that have been forced to migrate today as a result of climate change impacts. Using the Gilbertese resettlement from the Phoenix Islands to the Solomon Islands, in particular, Wagina Island in the 1960s as a case study of forced relocation and displacement of Pacific Islands people during the colonial period, this paper aims to underline some of the important lessons that can be learned from this historical case to inform the present and future challenges of climate change migration and displacement. Without dismissing migration as a coping strategy, the paper argues that the forced relocation of people from their home islands as a result of climate change will lead to displacement. It accentuates that in the case of Pacific Islands, forced relocation will lead to displacement if they are forced to leave their land because of their deep relationship and attachment to it. The paper also emphasizes the need to acknowledge and honor Pacific Islands' voices and perceptions in discourses on climate change migration and displacement at national, regional and international forums.
