Quick Answer: What is the effect of drought on agriculture in Australia?

Drought can also deplete water stores for animals and other farm uses. Current dry seasonal conditions across much of Australia have driven up feed and water prices, due to high demand and limited availability. This is impacting all farmers with the cost of grain alone being felt in all dairy regions.

What are the effects of drought on agriculture?

The effects of drought on crop production might be annual and perennial crop losses, damage to crop quality, income loss for farmers due to reduced crop yields, reduced productivity of cropland, insect infestation, plant disease, increased irrigation costs, cost of new or supplemental water resource development (wells, …

What is the impact of drought in Australia?

During drought, agricultural ecosystems suffer major damage. There is much loss of livestock and the growing of crops is disrupted. Declining productivity affects not only rural Australia but also the national economy. The impact of a drought may be felt for many years.

What impact does a drought have on the environment?

Drought can result in lower water levels in reservoirs, lakes and ponds, as well as reduced streamflow in rivers. This decrease in available water can also lead to a reduction of some wetlands, groundwater depletion and even impact water quality (e.g. salt concentration can increase).

How is agriculture in Australia affecting the environment?

The combined impacts of land and water use for agricultural production have been substantial. For example: The removal of native vegetation and the introduction of exotic species have contributed to the extinction and decline of many species of Australian wildlife (Hamblin 2001).

When have there been droughts in Australia?

Since the 1860s there have been nine major Australian droughts. The major drought periods of 1895-1903 and 1958-68 and the major drought of 1982-83 were the most severe in terms of rainfall deficiency and their effects on primary production.
