Summary
The 1982-1983 Australian drought severely impacted wheat and grain production, causing significant rural economic losses. This event ranks among the most severe droughts in the last century, highlighting the need for better drought mitigation strategies.
Area of Science:
- Agricultural Science
- Environmental Science
- Climatology
Background:
- Droughts pose significant risks to agricultural production and rural economies.
- Understanding historical drought impacts is crucial for developing effective mitigation strategies.
- The eastern Australian region is particularly vulnerable to drought events.
Purpose of the Study:
- To describe the development and severity of the 1982-1983 drought in eastern Australia.
- To assess the impact of this drought on agricultural production and rural economies.
- To evaluate the long-term implications of drought on environmental sustainability.
Main Methods:
- Analysis of meteorological data to track drought development.
- Economic analysis of agricultural production and rural income.
- Historical data review of agricultural and environmental impacts.
Main Results:
- The 1982-1983 drought significantly reduced national wheat production to 63% of the five-year average.
- Rural production value decreased from over $4,000 million to $2,300 million nationally.
- The drought is classified as one of the most severe in the last 100 years.
Conclusions:
- The 1982-1983 drought had devastating economic consequences for Australian agriculture.
- Exceeding environmental limits for grain growing and livestock populations may have occurred.
- There is an urgent need for enhanced strategies to mitigate drought impacts and promote sustainability.

02:41Responses to Drought and Flooding
Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
01:50Global 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.
01:57Adaptations 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.
01:00The Water Cycle
The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics.
01:03Precipitation Gravimetry
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

01:21Precipitation Titration Curve: Analysis
The precipitation titration curve demonstrates the change in concentration of one reactant with the volume of titrant added. During the titration of chloride ions with silver nitrate, the precipitation titration curve is divided into three regions: before, at, and after the equivalence point. Before the equivalence point, low redissolution of the sparingly soluble silver chloride precipitate gives a low silver ion concentration. However, in the second region, representing the equivalence point,...
