GEOG 106 Lecture Notes - Lecture 14: Hyperthermia, Coastal Erosion, Food Security
Document Summary
Global environmental change (gec) - the set of biophysical transformations of land, oceans, and atmosphere. Some examples of global environmental changes: loss of ocean fisheries, loss of biodiversity, deforestation, etc. Loss of biodiversity and declining freshwater are linked. This can result in loss of ecosystem services and water safety. Human security -a condition in which people and communities have the capacity to respond to threats to their basic needs and rights, so that they can live with dignity. 1 - climate change is projected to reduce renewable surface water & groundwater resources, intensifying competition for water among sectors. Climate change is projected to reduce raw water quality and pose risks to drinking water quality. 2 - due to the rise of sea level projections, coastal systems and low-lying areas will experience adverse impacts such as. 3 - for the major crops (wheat, rice and maize), climate change is projected to negatively impact production.
