Plant Breeding and Biotechnology

22.1K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Sustainable Development

15.4K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Adaptations that Reduce Water Loss01:57

Adaptations that Reduce Water Loss

28.5K
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.

Microorganisms in Agriculture and Food industry

1.8K
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:

  • Agricultural Science
  • Food Security
  • Climate Change Adaptation

Background:

  • Growing concern over global reliance on a few staple food crops.
  • Potential risk of a major food crisis due to limited crop diversity.
  • Need to critically assess the role of alternative crops in sustainable food systems.

Purpose of the Study:

  • To answer: "Are alternative crops needed for future sustainable food production?"
  • Critically analyze risks of staple crop reliance and the concept of alternative crops.
  • Evaluate candidate alternative crops and research needs, focusing on the Global South.

Main Methods:

  • Critical analysis of existing literature and crop characteristics.
  • Comparative assessment of staple, commonly grown, and alternative crops.
  • Review of knowledge gaps and research priorities for crop development.

Main Results:

  • Limited funding necessitates prioritizing improvements in existing staple crops.
  • Alternative crops may complement, rather than replace, staple crops.
  • Crop choices will be country/region and system-specific, requiring farmer consultation.

Conclusions:

  • Focus on enhancing staple crop stress tolerance and nutritional value is crucial.
  • Alternative crops can offer supplementary benefits but are not a primary solution.
  • Strategic, context-specific decisions are needed for future food security, involving all stakeholders.
