“…Studies have shown that in the past 20 years, with increasing global warming, the growth and distribution patterns of the species have changed significantly (Zhen-Feng, Jia & Shu-Qun, 2013; Zhao et al, 2014; Pacifici et al, 2017). The lack of climate data in the past 20 years may lead to a deviation in the conclusions from the actual situation.…”

Background Citrus huanglongbing (HLB) is a destructive disease of citrus and a major threat to the citrus industry around the world. This disease accounts for substantial economic losses in China every year. Diaphorina citri Kuwayama is one of the major vectors by which citrus HLB is spread under natural conditions in China. Research is needed to identify the geographic distribution of D. citri and its major areas of occurrence and to formulate measures for early warning, monitoring, and control of this pest and citrus HLB. Methods In this study, the ecological niche modelling software MaxEnt (maximum entropy model) was combined with ArcGIS (a geographic information system) to predict the potential geographic distribution of D. citri in China. Key environmental factors and the appropriate ranges of their values were also investigated. Results Our results show that the training data provided a good forecast (AUCmean = 0.988). The highly suitable areas for D. citri in China are mainly concentrated to the south of the Yangtze River, and the total area is 139.83 × 104 km2. The area of the moderately suitable areas is 27.71 × 104 km2, with a narrower distribution than that of the highly suitable area. The important environmental factors affecting the distribution of D. citri were min temperature of coldest month, mean temperature of coldest quarter, precipitation of wettest quarter, mean temperature of warmest quarter, precipitation of warmest quarter, max temperature of warmest month, and temperature seasonality. These results provide a valuable theoretical basis for risk assessments and control of D. citri. Discussion The predicted results showed that there were highly suitable areas for D. citri in Chongqing, Hubei, Anhui, and Jiangsu. Therefore, the possibility exists for the further spread of D. citri in China in the future. Extreme temperature variables, especially the min temperature of the coldest month, play an important role in the distribution of D. citri and are most closely related to the distribution of D. citri.

“…Climate change has impacts on the spatial distribution and relative competitiveness of pests and weeds (43), meaning that the applications of pesticides and herbicides need to be significantly changed in Northwest China. First, climate change has broadened the habitats of pests, causing pests to expand to higher latitudes and altitudes.…”

Northwest China has one of the most vulnerable agricultural systems in the context of global climate change. We argue that sustainable agriculture development in this region requires a systematic approach toward climate change adaptation, and propose a schematic framework for strategic thinking. We first briefly review the impacts of climate change on various agricultural environmental factors, including light, temperature, water, and atmosphere, and explores the effects of climate change on agricultural practices, such as disaster response, pests and weeds control, fertilizer application, and species selection. The study shows that climate change has increased extreme climate disasters such as drought and heat waves, and has expanded the scope and severity of pests and weeds, which in turn requires a series of changes in farming practices. These effects have profound impacts on farmland management, as well as the sustainability of the agricultural system. Based on the findings, the authors argue that the key adaptation strategies should include: (1) optimizing the geographic distribution of agriculture, (2) cultivating new crop varieties that can better adapt to the changing environment, (3) adjusting cropping timing and structure, (4) developing water-saving irrigation systems, (5) improving capacities of disaster prevention and mitigation at both household and government levels, and (6) strengthening the sciences, technology, and human resources to mitigate the adverse effects of climate change.

“…According to Zhao et al (2014), the adverse effects of climate change result in decreasing the number of regional water resources. Declining groundwater quality triggers an intrusion of seawater to the mainland, and sea level rise also contaminates the need for clean water and irrigation (UNDP Indonesia, 2007).…”

Climate change currently becomes the concern of policymakers and academics because the impact is already extensive. The Bajo People Community, located in Wakatobi, Southeast Sulawesi is a coastal community with a significant portion of its population living as fishermen. The people and fishermen in the Bajo people also felt the impact of climate change on the coastal and marine environment. The effect on the environment is very influential on the economic and social community of the Bajo People. This study aims to define the alternative to propose adaptation strategy to deal with climate change for fishermen. The benefit of this study is to provide input for planners, policymakers, and practitioners related to fisheries in the territory of Indonesia. Climate change adaptation is necessary to maintain the quality of life of fishers and to achieve the stability of available resources. This study used a literature study and Analytical Hierarchy Process (AHP) as its method to find the alternative strategy in order to face climate change. The plan proposed in this research are three, namely increasing knowledge and information about climate change, resource management, and livelihood diversification. The result of this research is that Bajo Fishermen need an appropriate adaptation strategy to mitigate the situation towards climate change issues, which is necessary to prevent the disruption of economic and social activities, focusing on the cognitive, practical and structured aspects that base on cultural values, norms, and customs of the Bajo people. This study found four useful variables to be used as coping strategies for climate change, which are social, ecological, economic and political alternatives. The four variables are strengthening the surveillance of epidemic disease, developing fish gear technology, improving proper water treatment management, and creating awareness of climate change for the fishermen community.
