打工人的续命水，快要喝不起了？

Core Viewpoint - The article discusses the impact of climate change on coffee production, highlighting the rising prices of coffee beans and the shift in farming practices in Yunnan, China, where farmers are increasingly growing coffee instead of traditional crops due to higher profitability [2][16]. Group 1: Coffee Price Dynamics - Coffee prices have surged, with the procurement price for fresh coffee fruit in Yunnan increasing from 3-5 yuan per pound to around 11 yuan, nearly tripling within a year [2]. - The price of raw coffee beans has also risen significantly, with some reports indicating prices reaching 80-100 yuan per kilogram, compared to 35-40 yuan in previous years [16]. Group 2: Climate Change Effects - Climate change is causing a reduction in the suitable growing areas for Arabica coffee, which is highly sensitive to temperature and rainfall changes [4][9]. - The production of Arabica coffee is expected to decline as climate conditions become less favorable, with predictions indicating that by 2050, suitable areas for coffee cultivation could decrease by about 50% [21][22]. Group 3: Coffee Production Challenges - The coffee cultivation process is lengthy, taking at least 5 years from seed to fruit-bearing, with optimal production occurring between 10-15 years [6]. - Factors such as excessive rainfall and drought are increasingly affecting coffee maturity and yield, leading to challenges in production [7][9]. Group 4: Pest and Disease Impact - Climate change is exacerbating pest issues, with the coffee borer beetle becoming more prevalent due to rising temperatures, leading to significant economic losses for coffee producers [9][11]. - The increased prevalence of pests and diseases is raising the cost of coffee production, further straining smallholder farmers who already operate on thin margins [19]. Group 5: Consumer Impact - Consumers may face higher prices for coffee as producers and companies pass on the increased costs associated with climate change and production challenges [19]. - Despite rising coffee bean prices, many consumers continue to purchase coffee at lower prices due to the relatively small proportion of coffee bean costs in the overall price of coffee products [16][18]. Group 6: Future of Coffee Production - The coffee industry is exploring the cultivation of more resilient coffee varieties that can withstand climate challenges, such as the Excelsa coffee variety, which is gaining attention for its drought and pest resistance [22][23]. - Companies are beginning to recognize the importance of sustainable practices to mitigate climate risks, with some, like Starbucks, committing to ethical sourcing and sustainable supply chains [24].
