“…With the increase in observation height, relative humidity decreased while wind velocity increased. A previous study mentioned that, besides elevation and terrain, soil type and soil texture also play decisive roles in the simulated vineyard microclimate in mountainous areas [26][27][28][29][30].…”

Vineyard microclimate is a main determining factor for grape yield and quality. In the Eastern Foothills of the Helan Mountains in the Ningxia region, China, grape is a critical economic crop for wine making. The microclimate of vineyards in 2019 and 2020 was analyzed on the basis of observations from eight vineyards microclimate stations and a national reference station. The vineyard microclimate was compared with the larger-scale local weather conditions, and the vineyard microclimate was compared within and among different climatic zones. In addition, the climate was evaluated at the four study wine grape areas. The results showed that: (1) In the same wine-grape-growing area where the climate was similar, vineyard microclimate was affected by elevation, topography, and soil texture. (2) Excepting average wind velocity, there were no statistically significant (p < 0.05) differences in minimum and maximum air temperatures or relative humidity between the study field microclimate observation stations and the local national reference station. (3) Among the four climate-zone-based wine-grape-growing areas, vineyard microclimate was related to topography, geographical location, and soil type. In particular, the Yinchuan and Qingtongxia areas had an abundant heat resource, and the Hongsipu area had sufficient precipitation and high photosynthetically active radiation (PAR). By contrast, the Shizuishan area had a relatively low-to-moderate amount of heat, precipitation, and radiation resources for grape. (4) According to the climate assessment of agricultural products—wine grape (QX/T 557—2020), the climate was superior in 2019 than in 2020 for wine grapes. In particular, the climate for grape was better in the Yinchuan area than in other study areas. The results of this study are evidence-based and could be used to assist the local wine grape community in making decisions about cultivars, management practices, area expansions, marketing strategies, etc.

“…Both options, long-term employment solutions and mechanisation, reflect the trend of modernisation and professionalisation. Mechanisation as a form of modernisation as an adaptation strategy has been the subject of the discourse on vineyard modernisations for a long time (Kaan Kurtural and Fidelibus, 2021;Sun et al, 2022). These reports have mostly highlighted rising wage costs, labour shortages, costeffectiveness, and timing as the multiple reasons for advancing mechanisation.…”

Climate change adaptation research among vine growers: evidence from Mátra wine region

Kivonat, rövid leírás This research contributes to the intensively growing climate change adaptation discourse with the examination of vine growers’ risk perception and risk management practices. In studies dealing with agricultural climate change adaptation issues, it is an often-cited statement that farming is a dynamic system that continuously responds to changing conditions. Such changing conditions are seen as risks induced by either climate change or other sources. This research systematically assessed these risks as a network of interrelated concepts, adopting a partially mixed sequential dominant research design, in which a quantitative research segment (a large sample of survey data) outlined the overall picture of Hungarian farmers' perceptions of climate change and adaptation behaviour and then an individual-based mental modelling approach was used to conduct a risk elicitation exercise embedded in qualitative interviews with vine growers. Despite the participants' diverse and complex mental models, the presence of a double pressure stood out from the results: one from the risks posed by the impacts of climate change, and another from the risks related to labour. The most obvious consequence of labour-related problems is that fewer and fewer people are willing and able to work in viticulture, which is a very labour-intensive activity. And risks that come with climate change, such as severe heat stress, lengthy droughts, and excessive UV radiation, will likely pose severe challenges for grape cultivation. Although the interaction of these two types of risks generates significant adaptation needs by exerting effects that should be addressed by a complex risk management approach, participants’ responses do not reflect this complexity. More precisely, participants’ responses indicate that in their multi-faceted risk landscape, labour-related risks have a greater influence on their risk management decisions than climate change related risks. This is well reflected in the evidence that their adaptation decisions have been focused on long-term solutions to labor-related problems, but only short-term decisions characterise their climate change adaptation behaviour. Despite all their perceived climate change related risks, participants still find themselves able to maintain their activities and keep cultivating grapes. This is because, on the one hand, climate risks are still seen as manageable with the available solutions, which consist primarily of tactical interventions. However, on the other hand, there appears to be considerable uncertainty regarding what should be done and how it should be done, so even these tactical interventions are surrounded by uncertainty. Multiple forms of uncertainty have been identified in this research, suggesting that if the climate situation worsens, the adaptive capacity of participants might be insufficient to cope with changes in climatic conditions.
