“…This trend is found to be more pronounced for the hilly areas (100-600 m) than for the plain areas (0-100 m), reflecting the higher climate sensitivity of grapevines at higher elevations (Caffarra and Eccel 2011). Figure 1 shows how grape yields in the Chianti area would change in 2020 and 2040 relative to the current level at six different elevations (from 0-100 m to 500-600 m) under climate scenario A1b.…”

This paper covers a comprehensive economic analysis of climate change adaptation options for a specific wine producing region, namely Tuscany. As temperature increases under climate change, rainfall patterns will be different, and Chianti wine production in Tuscany therefore needs to adapt in the near future. We address the adaptation challenges and identify grape yield and quality loss as the main impact of climate change on wine production. Relocation of vineyards uphill and introducing drought-resistant varieties are considered as adaptation measures. We appraise these adaptation measures using an optimization framework, where regional wine producers maximize income subject to economic constraints including the climate change impacts on wine productivity and quality. Our simulation shows quantitatively to what extent a higher degree of climate change impact demands a higher degree of adaptation. We find that a combination of the two measures provides a better strategy because it leads to higher economic efficiency. However, uncertainty regarding the efficiency of the new variety discourages the use of this new drought-resistant variety, whereas a higher efficiency would make this choice more favourable. Sensitivity analysis for time horizon and discount rate confirms the theory of investment under uncertainty, showing a shorter time horizon (or more frequent investment) provides the possibility to postpone the decision to implement adaptation measures due to the value of flexibility, while a higher discount rate leads to a later adaptation decision, because uncertainty creates a value of waiting for new information.

The Mediterranean Basin is a climate and biodiversity hot spot, and climate change threatens agro-ecosystems such as olive, an ancient drought-tolerant crop of considerable ecological and socioeconomic importance. Climate change will impact the interactions of olive and the obligate olive fruit fly (Bactrocera oleae), and alter the economics of olive culture across the Basin. We estimate the effects of climate change on the dynamics and interaction of olive and the fly using physiologically based demographic models in a geographic information system context as driven by daily climate change scenario weather. A regional climate model that includes fine-scale representation of the effects of topography and the influence of the Mediterranean Sea on regional climate was used to scale the global climate data. The system model for olive/olive fly was used as the production function in our economic analysis, replacing the commonly used production-damage control function. Climate warming will affect olive yield and fly infestation levels across the Basin, resulting in economic winners and losers at the local and regional scales. At the local scale, profitability of small olive farms in many marginal areas of Europe and elsewhere in the Basin will decrease, leading to increased abandonment. These marginal farms are critical to conserving soil, maintaining biodiversity, and reducing fire risk in these areas. Our fine-scale bioeconomic approach provides a realistic prototype for assessing climate change impacts in other Mediterranean agro-ecosystems facing extant and new invasive pests.ecological impacts | economic impacts | species interactions | Olea europaea | desertification

“…Communities were sampled only from lateral vine stocks of field grapevines in a restricted geographic region (Trentino, Northern Italy), with medium sandy, calcareous soils (48) characterized by humid, temperate, oceanic climate particularly in prealpine areas, with rainfalls maxima in the spring and autumn (16). Seven locations and a total of 28 vineyards were selected.…”

ABSTRACTWe studied the distribution of fungal endophytes of grapevine (Vitis viniferaL.) plants in a subalpine area of northern Italy, where viticulture is of high economic relevance. We adopted both cultivation-based and cultivation-independent approaches to address how various anthropic and nonanthropic factors shape microbial communities. Grapevine stems were harvested from several locations considering organic and integrated pest management (IPM) and from the cultivars Merlot and Chardonnay. Cultivable fungi were isolated and identified by internal-transcribed-spacer sequence analysis, using a novel colony-PCR method, to amplify DNA from fungal specimens. The composition of fungal communities was assessed using a cultivation-independent approach, automated ribosomal intergenic spacer analysis (ARISA). Multivariate statistical analysis of both culture-dependent and culture-independent data sets was convergent and indicated that fungal endophytic communities in grapevines from organically managed farms were different from those from farms utilizing IPM. Fungal communities in plants of cv. Merlot and cv. Chardonnay overlapped when analyzed using culture-dependent approaches but could be partially resolved using ARISA fingerprinting.
