14. •Current yield gain rate for major cereals is 1.3% simple linear rate.
But we require a 1.3% compound annual rate of yield gain to meet
demand on existing crop land.
•If yield increases are slower than demand, substantial expansion of
crop area, at thcarbon-rich natural ecosystemse expense of, will be
needed to maintain food security
•Associated GHG emissions from such land use change will accelerate
GHG emission rates, which could provide strong positive feedback to
rate of climate change

43. SUGGESTED STRATEGIES

44. 1. Efficient utilization of available water resources
•Bring more area under micro irrigation methods in phased manner through
appropriate land use planning at least at taluka level
•Creating awareness about micro irrigation methods among the farmers through
intensive training
• Permission for new tube wells should be granted only to those who adopt MIS
•Government should encourage those farmers showing inclination to adopt all
possible water saving techniques and facilitate for getting premium price for their
produce
•Appropriate technologies for saline water use needs to be developed and
popularized
•Fluoride problem need to be tackled in an integrated way

45. •Tank rehabilitation programme
•Promotion and support to community water conservation and recharge structure
•Increase vegetative cover in catchments areas for reducing runoff, reducing
sediment loss and increasing recharge
•In situ water harvesting through sub soiling
•Open well recharging
•Construction of percolation pits in the waste lands at 25 to 30 m apart
•Farm pond scheme under Sujalam- Suphalam
•Subsidizing and popularizing roof water harvesting through enforcement
2. Augmentation of water resources

46. Impacts of MIS
There will be saving of water to the tune of 59 BCM valued at
Rs.45000 crore.
The energy thus saved is estimated to be valued at Rs. 38000 crore.
The cumulative saving in fertilizer is estimated at Rs. 18000 crore.
Additional employment generation for about 21 m people.
The additional cumulative income to the farmers on account of
increased yield arriving from the adoption of MIS would be of the order
of about Rs. 64000 crore by the end of XI FYP and there after annual
additional income of Rs. 19000 crore.

estuarine, and near shore ecosystems and the human livelihoods and well
being that depend on them.

53. According to the natural flow paradigm of Poff et al. (1997), the flow regime is the
primary driving force that influences aquatic ecosystems. Flow is considered as the
master variable because it exerts great impact on aquatic habitat, river morphology,
biotic life, river connectivity and water quality.
Based on the hypothesis that the health of a river progressively deteriorates as more
and more water is withdrawn, and it significantly falls if the flow is below some
threshold value, the concept of minimum flows in rivers came into practice in the
1970s.

55. E- flows ensure a flow regime capable of sustaining a complex set of
aquatic habitats and ecosystem processes and are referred to as
“environmental flows”, “environmental water requirements”, “environmental
flow requirements”, “environmental water demand” etc.
Environmental flows are necessary to maintain the health and biodiversity
of water bodies, including rivers, coastal waters, wetlands (mangroves, sea
grass beds, floodplains) and estuaries. Note that besides the amount, one
should also specify the temporal pattern of the flows.

56. Environmental Flows and Water Resources Management in India
a.Most of the Indian rivers are excessively exploited to fulfill ever-increasing demand from hydro-
power generation, agricultural, industrial, municipal sectors and to control floods. There is
seasonal nature of rainfall and maximum structures for flow regulations.
b.Out of the 30 world river basins identified as global level priorities for the protection of aquatic
biodiversity (Groombridge and Jenkins, 1998), nine are in India and were singled out due to their
extensive and continuing development.
c.These basins are the Cauvery, Ganges-Brahmaputra, Godavari, Indus, Krishna, Mahanadi,
Narmada, Pennar and Tapi. Except for the Ganges-Brahmaputra, all these basins have also been
categorized as “strongly affected” by flow fragmentation and regulation (Nilsson et al., 2005).

57. “The current paradigm of river conservation programmes in India focuses mostly
on “Cleaning of Rivers” through sewage and industrial pollution management and
no attempt is made to treat the river ecosystem as a whole. Various challenges
that rivers face today reinforce the necessity to consider implementing
environmental flows (or E-Flows) in water resource management and for
improving the river health”
E-Flows are increasingly recognized as a key to the maintenance of ecological
integrity of the rivers, their associated ecosystems and the goods and services
provided by them.

58. Environmental Flow Assessment (EFA) Methodologies
The assessment of E-Flows aims to identify the quantity, quality and distribution of flow
patterns (timing) along the length of a river and provides a balance between the use and
protection of natural water resources for people and biodiversity.
Multi-disciplinary technical processes are required to carry out detailed studies relating to
hydrology, hydraulics, geomorphology, pollution etc.
While many countries in the world today have an E-Flows policy, the debate in India has
graduated from a rather narrow focus on ‘minimum’ flows to a much comprehensive
‘environmental’ flows.
