- Agricultural Engineering
- Environmental Science
- Sustainable Energy Systems
Background
- Viticulture faces climate change challenges like water scarcity and energy insecurity, especially in off-grid locations.
- Resource self-sufficiency and resilience are critical for sustainable agri-food systems.
Purpose Of The Study
- To propose and evaluate a circular water-energy integration strategy for off-grid viticulture.
- To enhance resource autonomy and resilience in wine production through system integration.
Main Methods
- Applied a mixed-methods framework combining technical monitoring and business model analysis.
- Utilized the Ecocanvas framework for system integration and PESTEL analysis for drivers.
- Evaluated a system in an off-grid winery in Spain (LIFE Climawin project).
Main Results
- Demonstrated technical feasibility and strong circular performance with sequential water reuse (approx. 1000 m³ per cycle).
- Achieved significant energy savings (38% heating, 56% cooling) using photovoltaic-powered heat pumps.
- Reduced diesel use by ~80% and CO₂ emissions by ~260 t CO₂eq (-76.5%) via smart microgrid control.
Conclusions
- Circular water-energy integration is a viable strategy for resource autonomy in off-grid viticulture.
- Ecocanvas is an effective tool for scaling circular transitions in agri-food SMEs.
- Findings can inform EU sustainability policies for the sector.

As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
In land plants, the uppermost cell layer of a plant leaf, called the epidermis, is coated with a waxy substance called the cuticle. This hydrophobic layer is composed of the polymer cutin and...
Open channel flow, where a fluid flows with a free surface exposed to the atmosphere, is primarily governed by gravitational and surface effects, distinguishing it from closed conduit or pipe flow. In open channels such as rivers, canals, and artificial channels, energy analysis provides valuable insights into flow behavior and the relationship between depth, velocity, and slope.Specific Energy and Flow DepthIn open channel flow, the specific energy, E, combines the gravitational potential...
Trapezoidal channels are widely used in irrigation systems due to their cost-effectiveness and efficiency in conveying water. Trapezoidal channels feature a flat bottom and sloping sides, making them stable and easier to construct compared to other shapes. The bottom width and side slope ratio are determined based on the required flow capacity and site conditions. The side slope is kept gentle for unlined channels to prevent soil erosion.Hydraulic parameters in channel design include the flow...
Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...
The xylem of vascular plants distributes water and dissolved minerals that are taken up by the roots to the rest of the plant. The cells that transport xylem sap are dead upon maturity, and the movement of xylem sap is a passive process.
Tracheids and vessel elements transport xylem sap
Tracheary elements are the transport cells of the xylem. They lack cytoplasm and organelles when they are mature and are considered part of the apoplast of the plant because they connect directly with the...
