Question

6.List the reasons for the
reduced availability of
freshwater for human
consumption.
​

Answer 1

Answer:

Overuse of water agricultural irrigation, domestic consumption and urban/industrial use may lead to water scarcity. Pumping too much water from underground supplies or river and streams can result in dried-up river beds and wetlands. The results can be catastrophic for wildlife and for human communities alike.

Explanation:

Climate change, such as altered weather-patterns (including droughts or floods), deforestation, increased water pollution and wasteful use of water can also cause insufficient water supply

Answer 2

Answer:

The essence of global water scarcity is the geographic and temporal mismatch between fresh water demand and availability. At the global level and on an annual basis, enough freshwater is available to meet such demand, but spatial and temporal variations of water demand and availability are large, leading to physical water scarcity in several parts of the world during specific times of the year. The main driving forces for the rising global demand for water are the increasing world population, improving living standards, changing consumption patterns (for example a dietary shift toward more animal products), and expansion of irrigated agriculture. Climate change (including droughts or floods), deforestation, increased water pollution and wasteful use of water can also cause insufficient water supply. Scarcity varies over time as a result of natural hydrological variability, but varies even more so as a function of prevailing economic policy, planning and management approaches. Scarcity can be expected to intensify with most forms of economic development, but, if correctly identified, many of its causes can be predicted, avoided or mitigated.[10]
