What is Climate?01:16

What is Climate?

21.3K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Microbes in Food Production01:29

Microbes in Food Production

21
Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically. Through...

Microorganisms in Agriculture and Food industry

1.9K
Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

Area of Science:

  • Food systems science
  • Sustainability studies
  • Social-ecological systems analysis

Background:

  • Unsustainability stems from current food systems, impacting environmental, economic, and social factors.
  • Sustainable food systems are crucial for improved societal welfare and policy redirection.
  • Food systems are complex social-ecological systems requiring integrated assessment tools.

Purpose of the Study:

  • To propose a conceptual model for understanding and enhancing food system sustainability.
  • To identify key vulnerability and resilience factors in food systems.
  • To address food and nutrition security as priority outcomes.

Main Methods:

  • Systems approach to analyze interdependencies within food systems.
  • Conceptual modeling to articulate vulnerability and resilience factors.
  • Application of the model to Mediterranean countries (Spain, France, Italy).

Main Results:

  • The conceptual model integrates environmental, economic, and social dimensions of sustainability.
  • It identifies critical factors influencing food system resilience and vulnerability.
  • The model provides a framework for tracking progress and informing policy.

Conclusions:

  • A systems approach is essential for addressing the complexity of sustainable food systems.
  • The proposed model aids in identifying and managing factors critical for food and nutrition security.
  • Policy interventions should foster public perception of human-nature interdependence for systemic sustainability.
