What is Climate?01:16

What is Climate?

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.
Global Climate Change01:50

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
Adaptations that Reduce Water Loss01:57

Adaptations that Reduce Water Loss

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.
Microbes and Climate Change01:27

Microbes and Climate Change

Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...
Threats to Biodiversity01:50

Threats to Biodiversity

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...
Responses to Heat and Cold Stress02:45

Responses to Heat and Cold Stress

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 Science
  • Climate Science
  • Food Security Studies

Background:

  • The Intergovernmental Panel on Climate Change (IPCC) has highlighted major risks to African agriculture due to climate change.
  • Recent impact assessments corroborate these concerns, indicating significant potential disruptions.

Purpose of the Study:

  • To review and synthesize recent climate change impact assessments on African agriculture.
  • To identify robust conclusions for policymakers and research agendas.

Main Methods:

  • Review of 14 quantitative and six qualitative climate change impact assessments.
  • Analysis of projected impacts across econometric, process-based, and statistical models.

Main Results:

  • Projected impacts on African agriculture vary widely, ranging from -100% to +168% across different assessment types.
  • All regions in Africa face risks of negative impacts on agriculture from climate change.
  • Existing agricultural systems and infrastructure require adaptation to meet future food demands.

Conclusions:

  • Climate change presents a substantial threat to African agriculture and food security.
  • Adaptation strategies for cropping systems and infrastructure are crucial.
  • Further scientific research is needed to determine how to significantly improve agricultural production in Africa amidst these challenges.
