- Goals: Ensure production while preserving the environment, economic resources, and social well-being.
- Focus: Management of fruit quality (yield, sustainable practices, harvest, and post-harvest handling).
Principles of Sustainability in Fruit and Grapevine Farming
Choice of Model Species (Apple and Hazelnut)
Apple:
- Characteristics: High specialization, intensive monoculture in some areas, high pesticide use.
- Standard Techniques: Dwarfing rootstocks, training systems (e.g., slender spindle).
- Primary Use: Fresh consumption.
Hazelnut:
- Characteristics: Variable intensity, moderate environmental impact, increasing energy needs.
- Main Regions: Europe (Spain, France, Italy).
- Uses: Food industry and local markets.
The Three Pillars of Sustainability
- Environmental: Biodiversity conservation, reduced chemical inputs, resource management.
- Economic: Cost-effective practices, profitability.
- Social: Worker safety, community involvement.
Current Agricultural Challenges
- Population Growth: Increased demand for food production.
- Climate Change: Impacts on resources (e.g., water, arable land).
- Need for Sustainable Intensification: Producing more with fewer inputs.
Strategies for Sustainable Intensification
- Precision Farming: Reduced inputs (pesticides, fertilizers).
- Biodiversity-Promoting Practices: Ground cover management, erosion reduction.
- Water Conservation: Sustainable water management techniques.
Crop Improvement through Breeding and Biotechnology
Conventional Breeding: Crossbreeding for disease resistance (e.g., scab-resistant apples).
Biotechnology (e.g., CRISPR/Cas9): Genetic modification for increased resilience (drought tolerance, enhanced photosynthesis).
Innovation Goals: Boost productivity and quality while reducing environmental impact.
Sustainability Measurement Indicators
Economic: Machinery costs, fuel, labor expenses.
Social: Worker safety, public health impacts, employee training.
Environmental: Nutrient efficiency, carbon footprint, biodiversity, waste management.
Comparison of Agricultural Practices
Mechanical Weed Management vs. Herbicides:
- Pros: Lower environmental impact.
- Cons: Higher costs for machinery and use.
Flame/Steam Weeding vs. Herbicides:
- Pros: No chemical pollution.
- Cons: Higher carbon footprint due to fuel usage.
Post-Harvest Quality and Disease Management
Goal: Reduce post-harvest diseases (e.g., in apples and pears), ensure quality through proper storage and handling.
Définition
Sustainable Intensification (Intensification Durable)
Approche visant à augmenter la production sur la même surface de terre en utilisant moins de ressources (eau, intrants chimiques) et en réduisant les impacts environnementaux.
Precision Farming (Agriculture de Précision)
Technique agricole utilisant des technologies avancées (GPS, capteurs, drones) pour optimiser l'utilisation des ressources, en appliquant les intrants seulement où et quand ils sont nécessaires.
Dwarfing Rootstock (Porte-Greffe Nanifiant)
Type de porte-greffe utilisé pour réduire la taille des arbres fruitiers, facilitant leur gestion et augmentant leur productivité dans certains systèmes intensifs.
Post-Harvest Handling (Gestion Post-Récolte)
Ensemble des pratiques pour maintenir la qualité des fruits après la récolte, en contrôlant les conditions de stockage, de transport et de conservation.
Abiotic Stress (Stress Abiotique)
Facteurs environnementaux non vivants (sécheresse, température, salinité) qui affectent la croissance et la productivité des plantes.
Root Volume (Volume Racinaire)
Capacité des racines d'une plante à explorer le sol pour l’eau et les nutriments. Augmenter ce volume peut aider les plantes à mieux résister aux périodes de sécheresse.
Circular Economy (Économie Circulaire)
Modèle économique visant à réduire le gaspillage en réutilisant et en recyclant les sous-produits. Par exemple, les déchets de taille peuvent être réutilisés comme biomasse.
