This movement was called Chipko Movement, In 1974 an Allahabad-based sports production company named Simond was given contract of cutting trees of Anguspecws in Chamoli district. The decision of auction of hundreds of acres of forest area found in the Renigaon of Chamoli created much dissatisfaction among the people. The forest department tried to pacify their revolt by inviting the menfolk of Renigaon and nearby villages to Chamoli for the payment of compensation for the role they had played during war time.

At the same time forest workers and laborers reached Renigaon to cut trees. The women of that village, in the absence of menfolk, came forward to resist cutting of trees by the forest laborers. They were saying that the forest is their parental home. They embraced trees for continuous two days and nights. They also broke the one arid only bridge of the entrance of the forest.

After this event Rigatoni became the battlefield of Chipko Movement. All over the Uttarakhand, people witnessed a new zeal to protect forests after this event. In order to speed up this movement Sundarlal Bahuguna walked 2800 km. Finally the State Govt, banned felling of forests in Renigaon area.

This mission involves consumer at the end point with land and water conservation programmed, specially stressing on his participation in the ongoing process and in maintenance. Under this mission stop dams and ponds were constructed for water storage on local public demand. As a result the quantity of available water increased, soil erosion was prevented, water became easily available for irrigation, plants and animals.

In 1999 the State Government made it compulsory for the Sarpanch of every Panchayat under ‘Ek Panch Ek Talab’ scheme to construct at least one new pond and reform the old during his office of five years. Thus, about 3412 ponds were rebuilt and 500 new ponds were constructed in a duration of less than 15 months. One-fourth of the cost was borne by the people. In the year 2000 under the ‘Pani Roko Abhiyan’ water storage was increased by making small dams.

This resulted in the development of 7 lacs water catchment area. Under the ‘Gaon Ka Pani Gaon Main Evam Khet Ka Pani Khet Mein’ programme, water was stored in the farms by constructing hedges. The efforts of water conservation made in Madhyi Pradesh were followed by other states too.

Question 1.
Describe the methods of Environmental Impact Assessment
Answer:
Environmental Impact Assessment is conducted in three stages:
Initial Scrutiny, Rapid Environmental Impact Assessment and Comprehensive Impact Assessment. Initial screening of a project is done to decide whether the impact assessment is actually needed for the project being under taken or not. If it is felt that the project is likely to cause some adverse effects on the environmental, it is subjected to Rapid Environmental Assessment.

Rapid Assessment attempts to identity the key issues in a particular project. Issues which are not important enough to require further studies are omitted. Comprehensive Environmental Assessment is undertaken after the Initial and Rapid Impact Assessment have been performed. Critical aspects of the project are taken up at this stage. If needed, the project may not be approved for implementation.
