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.

Applications of GIS: Disaster Management and Emergency Response

37
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Threats to Biodiversity

22.1K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Manipulation and Analysis

19
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...

Selected Data About Geographic Locations01:25

Selected Data About Geographic Locations

26
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Habitat Fragmentation02:31

Habitat Fragmentation

17.4K
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Area of Science:

  • Environmental Science
  • Food Systems Analysis
  • Sustainability Studies

Background:

  • The global food system faces significant environmental hazards, impacting societal stability.
  • A critical data gap exists in understanding the temporal trends, distribution, and equitable representation of these hazards across various information sources.
  • Existing literature and policy discussions may not fully capture the scope or geographical distribution of food system environmental risks.

Purpose of the Study:

  • To explore and quantify the data gap in understanding global food system environmental hazards.
  • To analyze the temporal trends and geographical distribution of hazard prevalence.
  • To assess the equity of hazard representation across research, policy, and news media.

Main Methods:

  • Leveraging global databases of research, policy documents, and news articles.
  • Analyzing trends in attention to food system hazards over time.
  • Mapping the geographical distribution of reported hazards.
  • Comparing the focus on different hazard classes across information sources.

Main Results:

  • Attention on food system hazards has increased over time, correlating with geopolitical events.
  • Geographical coverage of environmental hazards is unequal.
  • Media attention on hazards does not align with the focus in research and policy.
  • Climate change and water scarcity receive significant attention, unlike biodiversity loss or harmful algal blooms.

Conclusions:

  • Understanding and quantifying biases in hazard focus is essential to avoid environmental, financial, and food system sustainability damage.
  • Addressing the data gaps and uneven representation of hazards is a critical first step for informed decision-making.
  • A more equitable and comprehensive understanding of food system hazards is needed globally.
