Short-term climate conditions may affect crop yields and vintage quality and, as a consequence, wine prices and vineyards’ earnings. In this paper, we use a Computable General Equilibrium (CGE) model for Chile, which incorporates very detailed information about the value chain of the wine sector in the country. Using information for the 2015-2016 harvest, we calibrate climate variability shocks associated with a “bad year” for the wine industry in Chile, when premature rains occurred in important wine regions, reducing the area harvested and leading to wines with less concentrated flavors, particularly for reds. We model the climate shocks as a productivity change in the grape-producing sector (quantity effect). Moreover, we model quality effects as a shift in the foreign demand curve for Chilean wine. Given the specific economic environment in the model and the proposed simulation, it is possible to note the reduction of Chilean real GDP by about 0.067%. By decomposing this result, we verify that the quality effect has a slightly greater weight compared to the quantity effect.

Weather And Climate

Grapevines are highly sensitive to environmental conditions, with variability in weather and climate (particularly temperature) having a significant influence on wine quality, quantity and style. Improved knowledge of spatial and temporal variations in climate and their impact on grapevine response allows better decision-making to help maintain a sustainable wine industry in the context of medium to long term climate change. This paper describes recent research into the application of mesoscale weather and climate models that aims to improve our understanding of climate variability at high spatial (1 km and less) and temporal (hourly) resolution within vineyard regions of varying terrain complexity. The Weather Research and Forecasting (WRF) model has been used to simulate the weather and climate in the complex terrain of the Marlborough region of New Zealand. The performance of the WRF model in reproducing the temperature variability across vineyard regions is assessed through comparison with automatic weather stations. Coupling the atmospheric model with bioclimatic indices and phenological models (e.g. Huglin, cool nights, Grapevine Flowering Véraison model) also provides useful insights into grapevine response to spatial variability of climate during the growing season, as well as assessment of spatial variability in the optimal climate conditions for specific grape varieties.

Seasonal Climate

Seasonal climate outlooks provide one tool to help decision-makers allocate resources in anticipation of poor, fair or good seasons. The aim of the ‘Climate Outlooks and Agent-Based Simulation of Adaptation in South Africa’ project has been to investigate whether individuals, who adapt gradually to annual climate variability, are better equipped to respond to longer-term climate variability and change in a sustainable manner. Seasonal climate outlooks provide information on expected annual rainfall and thus can be used to adjust seasonal agricultural strategies to respond to expected climate conditions. A case study of smallholder farmers in a village in Vhembe district, Limpopo Province, South Africa has been used to examine how such climate outlooks might influence agricultural strategies and how this climate information can be improved to be more useful to farmers. Empirical field data has been collected using surveys, participatory approaches and computer-based knowledge elicitation tools to investigate the drivers of decision-making with a focus on the role of climate, market and livelihood needs. This data is used in an agent-based social simulation which incorporates household agents with varying adaptation options which result in differing impacts on crop yields and thus food security, as a result of using or ignoring the seasonal outlook. Key variables are the skill of the forecast, the social communication of the forecast and the range of available household and community-based risk coping strategies. This research provides a novel approach for exploring adaptation within the context of climate change.

The Relationship

Many scholars examine the relationship between climate variability and intrastate conflict onset. While empirical findings in this literature are mixed, we know less about how climate changes increase the risks for conflicts between countries. This article studies climate variability using the issue approach to world politics. We examine whether climate variability influences the onset and militarization of interstate diplomatic conflicts and whether these effects are similar across issues that involve sovereignty claims for land (territory) or water (maritime, river). We focus on two theoretical mechanisms: scarcity ( abundance) and uncertainty. We measure these concepts empirically through climate deviation (e.g. droughts/floods, heat waves/cold spells) and climate volatility (greater short-term variance in precipitation/temperature). Analyses of issue claims in the Western Hemisphere and Europe (1901–2001) show that greater deviations and volatility in climate conditions increase risks for new diplomatic conflicts and militarization of ongoing issues and that climate change acts as a trigger for revisionist states.

The Impact

AbstractThe objective of this paper is twofold: firstly, it analyzes the evolution of frauds in the Italian wine value chain over the period 2007–2015, and then, using a properly disaggregated social accounting matrix (SAM) of the Italian economy, it simulates the impact of wine frauds on the national economy in terms of growth, employment, value added and income. The wine industry is the sector most exposed to frauds within the Italian agro-food system accounting for 88% of total value of seized agro-food outputs. Most irregularities (95%) are made by only three agents, specifically individual wineries, bottlers-wholesalers and retailers. We estimated industry-specific SAM multipliers to assess the share of the Italian economy depending on irregular wine production. These activities account for 11.5% of specialized permanent crop farms output and over 25% of wine industry output. This is a sign of vulnerability of the wine industry: should a food scandal/scare determine a drop in consumers’ demand, the negative effect on production activities of these sectors may be large. The SAM was also used to perform an impact analysis adopting a counterfactual approach. Results show a slightly positive increase of value added (6 million euro) along with an overall decrease in the activity level (an output loss of 406 million euro and more than six thousand full time jobs lost). This contractionary effect can be explained with fraud rents. Indeed, the extra-profits from frauds do not activate the economy circular flow as most of them leak out to exogenous accounts such as the public administration and the rest of the world.

The Impact

This study examines the impact of increasing climate variability on food production in South Africa, focusing on maize and wheat yields. A two-way fixed effects panel regression model was used to assess the climate variability impacts, analysing secondary data for the period 2000 to 2019 for nine provinces in South Africa. The study found that increasing climate variability has a negative impact on maize and wheat production in South Africa. Specifically, the results indicated a negative correlation between mean annual temperature with both maize and wheat yields. A decrease in precipitation affected maize yields negatively, while the impact on wheat yields was positive, although insignificant. This analysis, therefore, depicted that crop yields generally increase with more annual precipitation and decrease with higher temperatures. The study recommends that funding initiatives to educate farmers on increasing climate variability and its effects on farming activities in South Africa should be prioritised.

AbstractSustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs (WCED, 1987). For the business community, sustainability is more than mere window-dressing. By adopting sustainable practices, companies can gain a competitive edge, increase their market share, and boost shareholder value (IISD, 2013). The wine industry has incorporated sustainability into its business strategy for a long time. In the USA, several industry organizations promoted its adoption by both grape growers and winemakers. In mountain wine regions, sustainability becomes more important as these regions generally struggle with reduced competitiveness due to inherent difficulties such as accessibility, remoteness, sparseness of business and population, topography and pedoclimatology (EUROMONTANA 2005). Therefore, any improvement in sustainability is a key factor for the viability of mountain wine producers. Sogrape Vinhos farms 480 ha of mountain vineyards in DWR securing the quality base of grapes for its SANDEMAN Port and CASA FERREIRINHA Douro wines. The company continuously adopted sustainable practices across the whole value chain, from grape to glass. This paper illustrates how a simple, but comprehensive, sustainability assessment, as proposed by a US-based award, can be used to monitor and improve sustainable development practices for a wine business set in an adverse environment, while raising awareness in a key market for wines produced in a mountain vineyard area such as the DWR.
