explain the difficulties for people living in low rainfall area
Answers
Answer:
The obvious problem is lack of surface runoff, often
characterized by desert conditions. A desert region has less than
10 inches of annual precipitation. Beyond the obvious, the problems
are many and diverse, which usually effect the way of life, the
local economy, limited or nonexistent agriculture, how people live
and make a living, which plants and animals adapt to the
conditions, how people obtain and conserve water and much more. In
spite of the lack of falling precipitation in a desert often it has
an abundance of subsurface water, sometimes close to the surface. A
desert Oasis is where that subsurface water rises above the
surface. In general, areas with low rainfall are more difficult to
live in, because after oxygen, water is critical to survival. For
that reason alone, in general deserts or desert like areas are less
populated. That is not to say, that people and economies can not
flourish in those regions, Dubai, and Las Vegas NV are examples of
that. What such regions lack in water, is compensated by another
source of water. What they lack in agriculture, and wildlife is
replaced by something else desirable, tourism, in demand natural
resources like oil or other things of value.
