Microorganisms in Agriculture and Food industry

346
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...

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

Area of Science:

  • Agricultural Science
  • Environmental Science
  • Ecosystem Management

Background:

  • Ecological safety of plateau-characteristic agribusinesses (PCABs) is vital for sustainable development.
  • Current evaluation methods lack expert knowledge integration, limiting scientific validity and practical use.
  • A need exists for improved methods to objectively assess PCABs' ecological safety.

Purpose of the Study:

  • To develop and validate a novel ecological safety evaluation method for PCABs.
  • To incorporate expert knowledge structures and varying granularity levels into the evaluation.
  • To provide a scientifically sound and practically applicable tool for PCAB management.

Main Methods:

  • Organizing knowledge points into a hierarchical structure (macro-, meso-, micro-levels).
  • Utilizing belief distribution functions for expert evaluations at different knowledge granularities.
  • Determining expert weights and reliability via entropy and similarity calculations.
  • Applying a generalized combination rule for progressive integration of multilevel evaluation information.

Main Results:

  • The proposed method successfully integrated multilevel expert knowledge.
  • A case study on a plateau specialty agribusiness showed its ecological safety status as "good."
  • The evaluation yielded high-quality group assessments.

Conclusions:

  • The knowledge granularity-based evaluation method is effective for assessing PCAB ecological safety.
  • The method enhances scientific validity and practical applicability compared to existing approaches.
  • Findings support targeted management recommendations for sustainable PCAB development.
