Question
What are the positive impacts of irrigation on the Indira Gandhi Canal Command Area?
Solution
Indira Gandhi Canal, previously known as the Rajasthan Canal, is one of the largest canal systems in India. The canal originates at Harike barrage in Punjab and runs parallel to the Pakistan border at an average distance of 40 km in the Thar Desert (Marusthali) of Rajasthan. The introduction of canal irrigation in this dry land has transformed its ecology, economy, and society. It has influenced the environmental conditions of the region both positively as well as negatively. The availability of soil moisture for a longer period of time and various afforestation and pasture development programmes under CAD have resulted in greening the land. This has also helped in reducing wind erosion and siltation of canal systems. It has led to a tremendous increase in agricultural and livestock production. The spread of canal irrigation has led to increasing in cultivated area and intensity of cropping. The traditional crops are sown in the area, gram, bajra, and jowar have been replaced by wheat, cotton, groundnut, and rice.

| Bharmaur tribal area comprises Bharmaur and Holi tehsils of Chamba district of Himachal Pradesh. It has been a notified tribal area since 21 November 1975. Bharmaur is inhabited by, Gaddi', a tribal community who have maintained a distinct identity in the Himalayan region as they practiced transhumance and conversed through Gaddiali dialect. Bharmaur tribal region has harsh climate conditions, low resource base and fragile environment. These factors have influenced the society and Economy of the region. According to the 2011 census, the total population of Bharmaur sub-division was 39,113 i.e., 21 persons per sq km. It is one of the most (economically and socially) backward areas of Himachal Pradesh. Historically, the Gaddis have experienced geographical and political isolation and socio-economic deprivation. The economy is largely based on agriculture and allied activities such as sheep and goat rearing. The process of development of the tribal area of Bharmaur started in the 1970s when Gaddis were included among 'scheduled tribes'. Under the Fifth Five Year Plan, the tribal sub-plan was introduced in 1974 and Bharmaur was designated as one of the five Integrated Tribal Development Projects (ITDP) in Himachal Pradesh. This area development plan was aimed at improving the quality of life of the Gaddis and narrowing the gap in the level of development between Bharmaur and other areas of Himachal Pradesh. This plan laid the highest priority on development of transport and communications, agriculture and allied activities, and social and community services. |
