FRAGILE ECOSYSTEM A fragile ecosystem is an ecosystem or community which lacks resilience or which is so heavily impacted by an 'un-natural' (human?) event that it changes in unexpected and undesirable ways leading into the conditions that are often termed as natural catastrophe . The fragile ecosystem, as can be claimed is the price paid by the humans for incessant development done at the cost of natural destruction

STUDY AREA BUNDELKHAND Occupies 70,000 square kilometers of the central plains in India, and stretches over twelve districts of northern Madhya Pradesh (MP) and five districts of southern Uttar Pradesh.

DROUGHT LIKE CONDITION EXCESSIVE EXPLOITATION OF GROUND WATER RISING POPULATION EXPANDING RAVINES DROUGHT LIKE CONDITION

SOME FACTS It has been noticed that out of 822 development blocks in 71 districts of the state, the ground water level in over 450 blocks were found to be in the category of the seriously affected. According to the figures obtained from Central Groundwater Board, water in 35.32 per cent wells of Tikamgarh had dropped two meters while water in 8.86 per cent wells has slipped more than 4 meters of the original level in the last 10 years. Under such conditions it is inconceivable for any farmer to be able to eke out a living out of agriculture. The decline in production of all grains during 2003-07 was 43.11 per cent while the yield of crop, which is defined as produce per hectare of land holding, declined by 22.13 per cent during the same time It was first reported in the dailies in 2007 on 11 August that 5 km away from the village Jigni of the district Rath ‘the earth had cracked to the length of 350m it was about 2.5 feet to 8 feet broad and 35 to 60 feet deep

EVEN AFTER BUNDELKHAND RECEIVED UNPRECEDENTED HEAVY RAINFALL THIS YEAR . Bundelkhand once again reported of land cracks that is 13 in Hamirpur and 5 in Jalaun district this was basically due to the fact as quoted by P N Razdan, Senior Deputy Director General, GSI, northern region. “Since Bundelkhand received deficient rainfall for the last four to five years, excessive exploitation of groundwater over this period has created a tension in the aquifer. Now with the sudden recharge of water due to incessant rains, fissures have opened up.”

MAJOR FINDINGS Formations of Fragile Zone has lead to - LIMITATION OF POPULATION SIZE INFLUENCE UPON POPULATION GROWTH DETERMINATION OF POPULATION EQUILIBRIUM LIMITATION OF AVAILABLE RESOURCES CHANGE IN ENVIRONMENTAL CONDITION DECREASE IN THE FERTILITY OF THE SOIL FORMATION OF CRACKS IN THE LAND

Formations of Fragile Zone has lead to -

WHAT NEEDS TO BE DONE: Practicing rain harvesting method. Adopt soil and moisture conservation measures. Review of ongoing schemes and programs . Enhance people's participation programs by creating mass awareness.

Enhance people's participation programs by creating mass awareness.

Practicing Sustainable Development- (6) Maximize the output and rate of growth. (5) Improve quality of life. (4) Promote equity in income distribution. (3) Reduce unemployment; Contribute to development (2) Solve or avoid environmental problems. (1) Optimally utilize natural and human resources Some Features of appropriate technology

WE ARE RESPONSIBLE FOR WHAT WE ARE, AND WHATEVER WE WISH OURSELVES TO BE, WE HAVE THE POWER TO MAKE OURSELVES. IF WHAT WE ARE NOW HAS BEEN THE RESULT OF OUR OWN PAST ACTION, IT CERTAINLY FOLLOWS THAT WHATEVER WE WISH TO BE IN FUTURE CAN BE PRODUCED BY OUR OWN PRESENT ACTION; SO WE HAVE TO KNOW HOW TO ACT. THANKYOU
