The Impact

<p>In the Mediterranean region, climate change is intensifying the need to improve the resource use efficiency of crops (e.g. water use efficiency) and to increase yield, quality and stability of productions, especially in high profitability and vulnerable crops as grapevine. In a climate change scenario, with increasing temperature and frequency of extreme events, such as prolonged periods of drought, the improvement of knowledge about the plasticity of morpho-functional traits in vines, becomes pivotal. Only a deep knowledge of vine responses to environmental constraints can help achieving the correct management of cultivation factors towards sustainability.</p><p>The objective of this study is to apply a multidisciplinary approach for monitoring the resource use efficiency and resource allocation during vine development up to wine production. This general objective will be pursued by analysing the complex relationships between parameters in the continuum environment/plant/wine with specific emphasis on the influence of water availability on the vine, grapes, must and finally wine, in order to relate climate, plant water status and oenological characteristics.</p><p>The study was conducted in a vineyard of Vitis vinifera L. subsp. vinifera ‘Falanghina’ located in southern Italy (La Guardiense farm, Guardia Sanframondi, Benevento, Campania region).</p><p>The vineyard performance was monitored on the basis of several morphological and eco-physiological parameters, measured in the main phenological phases, including: plant architecture, fertility, leaf anatomical traits, photosynthetic efficiency, leaf gas exchanges, nutritional status, berry and must quality. Water use efficiency was estimated through the analysis of anatomical and stable isotope traits (linked with hydraulic and resource efficiency parameters) from tree-ring series and leaf samples. Stable isotopes were also analysed in the must, in order to check the occurrence of an isotopic signature from the plants towards the must.</p><p>The approach proved to be promising for achieving a comprehensive understanding on the impact of environmental constraints not only on plant behaviour, but also on the characteristics of the oenological products, furnishing at the same time a promising tool to reconstruct vine status from the isotopic trace in the must.</p><p> </p>

The Impact

<p>Climate change is one of the main challenges for future agriculture since it can severely affect plant growth and development. The Mediterranean area is one of the most vulnerable regions where climatic models have forecasted a significant increase in frequency and severity of drought events. Ongoing climate change is aggravating some critical issues in the production of the autochthonous grape variety Greco, widely cultivated in the Campania Region (southern Italy) and used alone or blend in many quality label wines.</p><p>Nowadays, there is a high risk for the economic sustainability of Greco cultivation due to the following main issues: reduced vine productivity, low selling price of grapes, and territory fragmentation. Such criticisms induce the abandonment of small/medium-sized farms due to either crop conversion or consolidation into larger farms.</p><p>The Greco variety may represent a study model to introduce innovative and integrated management of cultivation techniques, such as pruning and soil management, with the aim to resolve similar problems affecting other autochthonous regional cultivars. They include issues, such as low fertility, that cause an unbalanced ratio among sugars, acids, and affect grape metabolites important for the oxidative stability and sensory quality of wine.</p><p>The GREASE project, funded by Campania Region within the Rural Development Programme 2014-2020, falls within the framework of sustainable management of vineyards (from economic, environmental and social viewpoints) with an insight to climate change. The general objective to improve the potential production of Greco concerns the management of major cultivation practices in viticulture by the realization of a cultivar-specific model for vine canopy and soil management. Optimization of parameters is important in order to achieve a good vegetative and reproductive balance that enhances grape and wine quality, improves farm profitability and environmental sustainability. This project is conducted in a vineyard of Vitis vinifera L. subsp. vinifera ‘Greco’ located in southern Italy (Feudi di San Gregorio farm).</p><p>The projects has 3 main inter-disciplinary actions: A1) to determine the effect of diverse vine pruning systems on plant resource use, through the reconstruction of vine eco-physiological history (dendro-anatomical and -isotopic analyses); A2-A3) to analyse the effect of soil management and of vine training systems on the continuum soil-plant-atmosphere system. Specific activities include: pedoclimatic, vegetative and reproductive, physiological and hydraulic characterization; microvinification and characterization of grapes and wine produced in the different trials; evaluation of resources use efficiency, pests, footprint family markers; model development.</p><p>The impact of the project on other wineries of the Campania Region will be significant due to an increased understanding of how cultivation systems influence the efficient use of available resources in the Greco vineyard. Such knowledge would be useful to design simple modifications to the presently used agronomical practices, to achieve production and economic gains without long-term structural investments. This know-how will also favour other downstream technologies and biotechnologies of viticulture and enology production, as well as the associated companies (e.g., producers of fertilizers, seeds for green manure) to realize products and services better adapted to the development of cultivar-specific viticultural and enological production systems.</p>

Absorbed Photosynthetically Active Radiation

It was demonstrated that conventional resource use efficiency (RUE) estimation methodology is largely subject to arithmetic weakness. Extensive field research data on aboveground biomass (AGB), absorbed photosynthetically active radiation (APAR), and crop evapotranspiration (ETc) in maize, soybean, sorghum, and winter wheat confirmed this methodological bias for light use efficiency (LUE) and water use efficiency (WUE) estimation. LUE and WUE were derived using cumulated (data aggregates across samplings) and independent (data increments across samplings) approaches. Use of cumulated data yielded strong-but-false correlation between AGB and APAR or ETc, being a statistical artefact. RUE values from an independent approach were substantially lower than that from a cumulated approach with greater standard errors. Overall, a cumulated approach tends to oversimplify the complex interactions among carbon and resource coupling in agroecosystems, which is accurately represented when employing an independent approach instead.

Abstract. The international trade of food commodities links water and food systems, with important implications for both water and food security. The embodied water resources associated with food trade are referred to as "virtual water trade". We present the first study of the impact of climate change on global virtual water trade flows and associated savings for the year 2030. In order to project virtual water trade under climate change, it is essential to obtain projections of both bilateral crop trade and the water-use efficiency of crops in each country of production. We use the Global Trade Analysis Project (GTAP) to estimate bilateral crop trade flows under changes in agricultural productivity. We use the H08 global hydrologic model to estimate the water-use efficiency of each crop in each country of production and to transform crop flows into virtual water flows. We find that the total volume of virtual water trade is likely to go down under climate change. However, the staple food trade is projected to save more water across most climate impact scenarios, largely because the wheat trade re-organizes into a more water-efficient structure. These findings indicate that trade may be an adaptation measure to climate change with ramifications for policy.

New Breeding Technologies

Plant related innovations are critical to enable of food security and mitigate climate change. New breeding technologies (NBTs) based on emerging genome editing technologies like CRISPR/Cas will facilitate “breeding-by-editing” and enable complex breeding targets—like climate resilience or water use efficiency—in shorter time and at lower costs. However, NBTs will also lead to an unprecedented patent complexity. This paper discusses implications and potential solutions for open innovation models.

Coffee (Coffea spp.) represents one of the most important sources of income and goods for the agricultural sector in Central America, Colombia, and the Caribbean region. The sustainability of coffee production at the global and regional scale is under threat by climate change, with a major risk of losing near to 50% of today’s suitable area for coffee by 2050. Rain-fed coffee production dominates in the region, and under increasing climate variability and climate change impacts, these production areas are under threat due to air temperature increase and changes in rainfall patterns and volumes. Identification, evaluation, and implementation of adaptation strategies for growers to cope with climate variability and change impacts are relevant and high priority. Incremental adaptation strategies, including proper soil and water management, contribute to improved water use efficiency (WUE) and should be the first line of action to adapt the coffee crop to the changing growing conditions. This research’s objective was to evaluate at field level over five years the influence of fertilization with calcium (Ca+2) and potassium (K+) on WUE in two coffee arabica varieties: cv. Castillo and cv. Caturra. Castillo has resistance against coffee leaf rust (CLR) (Hemileia vastatrix Verkeley and Brome), while Caturra is not CLR-resistant. WUE was influenced by yield changes during the years by climate variability due to El Niño–ENSO conditions and CLR incidence. Application of Ca+2 and K+ improved the WUE under such variable conditions. The highest WUE values were obtained with an application of 100 kg CaO ha−1 year−1 and between 180 to 230 kg K2O ha−1 year−1. The results indicate that adequate nutrition with Ca+2 and K+ can improve WUE in the long-term, even underwater deficit conditions and after the substantial incidence. Hence, an optimum application of Ca+2 and K+ in rain-fed coffee plantations can be regarded as an effective strategy to adapt to climate variability and climate change.
