CHANGES IN THE LOCALITY
The environment undergoes constant changes over a period of time. But due to pressure from
modernization , urbanization and industrialization there is a sudden spurt in the changes
occurring in every aspect of our environment. It is due to changes in biodiversity, climate, land
use and water bodies.
1. The way people are dependent on local and global ecosystem services :- Ecosystem
services are broadly subdivided into provisioning, regulating, cultural and supporting
services for our daily requirements of food, water, climate, clothing and shelter. There is a
major shift in the people as well as provisioning ecosystem services are connected.
A. Provisioning ecosystem services:-
1). Water :- Women of the house usually from the rural area used to fetch water from wells,
tanks etc in their neighborhood.
2). Food :- Due to globalization , fruits and crops grow in four countries are reaching Indian
markets , now owing to biotechnological innovations. Green revolution has created abundance
of food. The white revolution has indeed made milk easily available everywhere at anytime.

rural areas gobar gas has made an impact.
4). Timber and Fiber :- There is a shift in the utilization of timber for the purpose of furniture
and as a building material. Fiber like cotton or pure silk have replaced nylon, terylone, terecot
etc. are popular these days.
B. Regulating ecosystem services :- Since the loads of waste are being dumped into the
environment, regulating ecosystem services are falling short.
C. Cultural ecosystem services :- This is provided to people from their daily and stressful
routine. Thus aspects are vanishing due to human encroachment and destruction of natural
areas.
D. Supporting ecosystem services :- Soil formation or nutrient cycling are hampered due to
human interference.
2. Land Use :- No vacant land is available in mega cities. It is due to rising towers, sprawling
industries and conversion of agricultural land into other purpose have posed a great threat
in landscape.
3. Population :- The population is said to be a monster that is eating up our country. It has
resulted in the depletion of almost all resources.
