Sustainable Development

14.1K
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.

Production Efficiency01:01

Production Efficiency

17.3K
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

Design Example: Sustainability in Concrete Building

269
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

Summary
This summary is machine-generated.

A new scoring method evaluates beef production sustainability comprehensively. Semi-intensive silvopastoral systems and well-managed pasture-fed beef are most sustainable, unlike extensive grazing or feedlots.

Area of Science:

  • Environmental Science
  • Agricultural Science
  • Animal Science

Background:

  • Resource management decisions require comprehensive scientific data.
  • Current sustainability assessments often use limited factors.
  • Incomplete evaluations can lead to suboptimal choices regarding food production systems.

Purpose of the Study:

  • To present a scientifically-based scoring method for evaluating the sustainability of beef production.
  • To identify key components of sustainability in beef production systems.
  • To compare the sustainability of different beef production methods.

Main Methods:

  • Developed a scoring system incorporating biological and other scientific information.
  • Reviewed various sustainability components of beef production.
  • Applied the scoring method to compare different beef production systems.

Main Results:

  • Significant variations in sustainability exist among beef production systems.
  • Extensive grazing and feedlot systems with grain feeding are least sustainable.
  • Semi-intensive silvopastoral and well-managed pasture-fed systems demonstrate higher sustainability.

Conclusions:

  • A comprehensive, scientifically-based scoring system improves policy formulation for beef production.
  • Considering diverse sustainability factors is crucial for accurate system evaluation.
  • The developed scoring system offers value for policymakers, researchers, producers, and the public.
