1) The study analyzes water productivity in the Indrawati Basin of Nepal, calculating agricultural, livestock, and energy productivity ratios based on crop yields, water consumption, milk/meat/egg production, and energy/water discharge.
2) The water productivity of the Indrawati Basin was found to be 1.4 Kg/m3, higher than Nepal's national average of 0.8 Kg/m3 but still considered low. Productivity varied between villages from 0.3 to 5.6 Kg/m3.
3) Total water use in the basin is 391 mm, showing potential for more efficient water use to improve livelihoods and development, as people experience

WATER SHORTAGE ITS CAUSES, IMPACTS AND REMEDIAL MEASURESIN PAKISTANFarhan Hussain
with two thirds of the earths surface covered by water, it is evidently clear that water is one of the most important elements responsible for life on earth. It is not only vital for sustenance of life but equally essential for the socioeconomic development. The global fresh water shortage and food security issues related to teeming billions of population necessitated the shifting of fresh water from agriculture to other more pressing uses. The country is facing the worst ever crises of water shortage for last many years, as water available for any given use has become increasingly scarce.
WorldFish representative gave this presentation on a case study of how communities of Keosenkham Village (Laos) have adapted livelihoods to the constructed hydropower reservoir.
Water management is a global issue and it is the prime duty of all the people to save and conserve water so that it can be passed on safely to the future generation. Viewers please watch the ppt and leave your likes and comments.

India has about 18 percent of the world’s population and only 4 percent of the world’s water resources. It is severely water-stressed, thereby making water management a national priority. India uses about 230 cubic kilometers of groundwater annually, which is more than a quarter of the global total, making it the world’s largest user of groundwater.

INDIAN SCENARIO OF WATER RESOURCES - AN OVERVIEW, INTEGRATED WATER MANAGEMENT...Venkataraju Badanapuri
Water is life sustaining liquid. It is one of the most important natural resources which is essential for the existence of living organisms and things including humans and wildlife, food production, food security, sustainable development and alleviate the poverty of the country. Despite of having blessed with enormous water resources (e.g., Mt. Himalaya’s originated Holy River Ganges, and its several tributaries from the north, Kaveri River in the south, ever rain forests [e.g., Mousinram near Cherrapunji], world’s tastiest waters of the Siruvani River in Coimbatore, Western Ghats Basin, network of fresh water resources etc.,), “water problem” is huge ‘a big threat and cross cut problem in India’. Water is most essential and widely distributed key resource to meet the basic need for livelihoods,
1. Analysis of Water Productivity in
Indrawati Basin, Nepal

2. Water Productivity
• Water productivity broadly denotes the outputs
(goods and services) derived from a unit volume of
water. The ratio of the net production of crop, forestry, fishery, livestock,
and mixed agricultural systems to the amount of water required to produce
those items.
• Nepal is rich in water resources but it is a food-
deficit country
• Water management is a key to water productivity
and it helps improve livelihood, economy and
development
3. Water Productivity-contd.
Luxemburg has highest water productivity in the world.
Its WP has increased from 147 in 1987 to 429 in 2009.
Country WP km/m3 (Year 2009)
Bangladesh 2.2
Bhutan 2.6
India 1.2
Maldives 196.9
Nepal 0.8
Pakistan 0.6
Sri Lanka 1.9

4. Study Area: Indrawati basin
• Located in central region of
Nepal
• between latitudes 270 37’ 11” to
280 10’ 12" North and longitudes
85o 45’ 21” to 85o 26’ 36” East.
• Area: 1240 Sq. Km
• Economic activity in the basin is
largely limited to subsistence-
based and commercial
agriculture
• Food security is a major concern
5. Methods
• Data collection:
- field/primary data: questionnaire, random sampling and
stakeholders meeting
- secondary data: demography, statistics, agriculture, hydro-met
• Water productivity calculation:
- Agricultural water productivity
- Livestock water productivity
- Energy productivity
• Analysis and interpretation
6. Water productivity Analysis
Agriculture Water Productivity
For the basin area, physical water productivity (Kg/m3) was calculated using the formula,
WP= Output/Q
WP is the water productivity (Kg/m3),
Output is the crop yield (Tons), and
Q is water supplied or consumed (m3)
Water productivity (WP) of VDC=Total annual land production in VDC/effective rainfall
7. Water productivity Analysis-contd.
Livestock Water Productivity
This was calculated with reference to field and socioeconomic data.
WP= Total milk produced /q
WP= Total meat produced /q
WP= Total egg produced /q
Where, q is water consumed by livestock
Energy Productivity
Energy productivity was calculated directly as energy production and water discharge in
m3/s
WPe= energy produced /q1
Where, q1 is water discharge
8. Results and discussion
• The water productivity of the
Indrawati basin was found to be
1.4 Kg/m3 which is higher than
the national average 0.8 Kg/m3
but still considered very low.
• VDC level water productivity in
the Indrawati basin ranged
from a minimum of 0.3 Kg/m3
in Thakani VDC to a maximum
of 5.6 Kg/m3 in Anaikot VDC.
9. Results and discussion
• The annual rainfall in Indrawati basin varies from about 1100 mm in the
lower part to over 2500 mm in the upper part.
• Total water use in the basin is 391 mm showing that the water productivity
in the basin is very low and there is good potential for more efficient use of
water for the better livelihoods of the local people and sustainable
development.
• People are experiencing more erratic and lower rainfall in the basin and
upstream water sources are drying out. This may be further aggravated in
future due to climate change. Measures such as water harvesting, recharging
of the water sources, restoration of degraded areas /forests are urgently
needed.
10. Results and discussion-contd.
• Low water consuming agro-technology should be promoted. There are good
opportunities for vegetable farming including agro products with market linkages
given the basin’s proximity to the capital city Kathmandu; this could significantly
improve the livelihood of local communities.
• Efforts by the local people alone are not enough to increase their productivity. The
government and other relevant agencies should be aware and support them to
take actions to increase the productivity.
• Capacity of the local communities should be enhanced on sustainable practices for
the management of water and related natural resources.
