What is Climate?01:16

What is Climate?

18.4K
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.

Adaptations that Reduce Water Loss

25.2K
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.

Responses to Salt Stress

13.1K
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Key Elements for Plant Nutrition

18.7K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Area of Science:

  • Agricultural Economics
  • Public Health
  • Food Security Studies

Background:

  • Food security is crucial for global economic development and social stability.
  • China's agricultural sector faces challenges in ensuring adequate food supply and nutrition.
  • Measuring progress in hunger eradication and nutrition improvement is essential.

Purpose of the Study:

  • To measure the efficiency of hunger eradication, food security, and nutrition improvement in China.
  • To analyze the impact of rainfall as an exogenous variable on these efficiencies.
  • To identify regional disparities and stage-specific needs in China's food security efforts.

Main Methods:

  • Utilized panel data from 29 Chinese provinces (2016-2020).
  • Employed the Meta Entropy Two-Stage Dynamic Direction Distance Function (DDF) under an exogenous Data Envelopment Analysis (DEA) model.
  • Selected indicators include foodborne and iodine deficiency diseases, child stunting, malnutrition, obesity rates, and newborn visit rates.

Main Results:

  • China's agricultural economic sustainability is currently insufficient.
  • Average efficiency in hunger eradication, food security, and nutrition improvement shows a decreasing trend across eastern, western, and central regions.
  • The effectiveness of these measures varies across different developmental stages.

Conclusions:

  • Continued investment in agricultural infrastructure is necessary.
  • Increased policy support for green agricultural production is recommended.
  • Promoting agricultural production diversification and varied consumption of agricultural products can enhance food security.
