“…Increased warming with associated increased evapotranspiration and increased frequency and intensity of extreme events such as droughts, wildfires floods, and heatwaves [142] will bring increased pressure for irrigation and less reliance on precipitation, more so for old world producers than new world producers [92]. For South Africa, this situation is especially dire because the country is one of the most water-scarce countries in the world, with large areas classified as arid or semi-arid [27].…”

The 3Ps (Profit, Planet, and People) of Sustainability amidst Climate Change: A South African Grape and Wine Perspective

Conventional agriculture has made the search for sustainability urgent, more so with regards to climate change. This has extended to the grape and wine industry, an important industry in South Africa in terms of labor employment and foreign exchange. This paper aims to review the current state of knowledge with regards to the three pillars of sustainability and with regards to climate change. In order to understand sustainability in South Africa, a historical context is needed, because the welfare of farm workers still retains vestiges of past Apartheid. Ecological responsibility and higher profits are the main reasons for sustainable practices. Additionally, water use, chemical use, and soil erosion are important environmental sustainability concerns. With regards to climate change, in terms of economic sustainability, there will be winners and losers and social sustainability issues will intensify as changes occur in farms. Table grape producers are relatively more profitable than wine grape producers. Furthermore, pest, disease, irrigation pressure will worsen as the climate warms. However, there are long- and short-term adaptation strategies such as changes in viticulture practices and grape cultivars, respectively, to stem the effects of climate change, but this may be stymied by cost and farmers’ perceptions of climate change.

“…Considerable research has been conducted on the three individual pillars of sustainability and in the context of climate change in the South African grape and wine industry [25][26][27][28][29][30]. However, a major gap in these studies is the provision of a holistic overview of the three pillars in tandem.…”

“…Nowadays, the wine industry is one of the most actively researched areas in relation to climate change, taking into account the related sustainability challenges and opportunities in many different scientific and geographical areas [12][13][14][15]. Numerous studies can be found that consider viticulture and climate change-related issues from Europe [16][17][18][19][20], North-and South-America [21][22][23][24], South-Africa [25][26][27], and Australia [28][29][30].…”

Climate Vulnerability and Adaptation Challenges in Szekszárd Wine Region, Hungary

Wine producers face several challenges regarding climate change, which will affect this industry both in the present and the future. Vulnerability assessments are at the forefront of current climate research, therefore, the present paper has two main aims. First, to assess two components of climate vulnerability regarding the Szekszárd wine region, Hungary; second, to collect and analyze adaptation farming techniques in terms of environmental sustainability aspects. Exposure analyses revealed that the study area will face several challenges regarding intensive drought periods in the future. Sensitivity indicators show the climate-related characteristics of the most popular grapevines and their relatively high level of susceptibility regarding changing climatic patterns. Since both external and intrinsic factors of vulnerability show deteriorating trends, the development of adaptation actions is needed. Adaptation interventions often provide unsustainable solutions or entail maladaptation issues, therefore, an environmental-focused sustainability assessment of collected interventions was performed to avoid long-term negative path dependencies. The applied evaluation methodology pointed out that nature-based adaptation actions are preferred in comparison to using additional machines or resource-intensive solutions. This study can fill the scientific gap by analyzing this wine region for the first time, via performing an ex-ante lock-in analysis of available and widely used adaptation interventions in the viticulture sector.

The current literature on productivity growth analysis in South Africa often overlooks two key factors, namely the weather effects and pollution-related issues. This study aims to address the first of these gaps by utilising a decade’s worth of panel data from the Table grape industry in the country. We conduct a comparison between Färe-Primont Index that ignores environmental change and statistical noise, and; Proper Index. The latter offers a measure of sustainable productivity, decomposing into technical change, technical efficiency, scale efficiency, mix efficiency, environmental change (weather effects), and statistical noise. In simpler terms, the Färe-Primont Index results in conventional growth (TFP), while the Proper Index leads to sustainable TFPI growth (TFPI). Our findings reveal that ignoring weather effects and statistical noise leads to an increase in TFP. However, accounting for these factors results in a decline in TFPI. Despite this decline, weather effects had an average 0.11% positive impact on TFPI growth. We conclude that weather effects posed a lesser challenge to TFPI growth during the observed period compared to technical change (−4.80%) and scale-mix inefficiency (−0.76%). Therefore, we recommend that the table grape industry prioritise investment in research and innovation as a strategy to improve technical change and improve infrastructure such as irrigation systems, roads, and storage facilities to reduce costs, increase the scale of production, and thus improve scale efficiency. Government policies, such as funding for technology adoption and encouraging diversification, can improve mix efficiency. Future studies should strive to address the second gap in the literature by focusing on pollution-related issues.
