C4 Pathway and CAM01:27

C4 Pathway and CAM

38.0K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

Bioremediation00:46

Bioremediation

17.4K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Plant Breeding and Biotechnology01:59

Plant Breeding and Biotechnology

17.2K
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.

Transgenic Plants02:50

Transgenic Plants

7.0K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Estimation of the Physical Quantities01:05

Estimation of the Physical Quantities

6.7K
On many occasions, physicists, other scientists, and engineers need to make estimates of a particular quantity. These are sometimes referred to as guesstimates, order-of-magnitude approximations, back-of-the-envelope calculations, or Fermi calculations. The physicist Enrico Fermi was famous for his ability to estimate various kinds of data with surprising precision. Estimating does not mean guessing a number or a formula at random. Instead, estimation means using prior experience and sound...

Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

873
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Area of Science:

  • Agricultural Science
  • Environmental Science
  • Sustainability Studies

Background:

  • Growing global population and consumption patterns are straining agricultural systems and natural resources.
  • Current agricultural practices contribute to land degradation, water depletion, biodiversity loss, and climate change.
  • A significant portion of the world's population faces chronic malnutrition, highlighting food insecurity issues.

Purpose of the Study:

  • To analyze strategies for meeting future global food security and sustainability needs.
  • To identify methods for substantially increasing food production while minimizing agriculture's environmental footprint.
  • To address the dilemma of feeding a growing population without further degrading the planet.

Main Methods:

  • Analysis of agricultural expansion trends and their environmental consequences.
  • Assessment of 'yield gap' closure potential on underperforming agricultural lands.
  • Evaluation of cropping efficiency improvements, dietary shifts, and waste reduction measures.

Main Results:

  • Halting agricultural expansion is a key strategy for reducing environmental impact.
  • Closing yield gaps on underperforming lands can significantly boost food production.
  • Integrated strategies including dietary shifts and waste reduction can double food production.

Conclusions:

  • A combination of strategies can sustainably double food production.
  • Reducing agricultural expansion and improving efficiency are crucial for food security.
  • Sustainable agriculture is achievable through targeted interventions and systemic changes.
