Water Poverty Analysis IGB Basin Focal project Upali Amarasinghe, Stefanos Xenarios Rajendran Srinivasulu, Dhrubra Pant, Madar Samad BFP: Water-Poverty Analysis Setting the Context IGB Riparian countries has: • 1.3 billion people in 2000 – 380 million (29%) are poor • 942 million (72%) rural population – 340 million (36%) are poor IGB has: •605 million people -191 million (32%) are poor •454 million (75%) rural populatio -151 million (33%) are poor Poverty is a rural phenomena Poverty trends Pakistan 70 60 60 50 50 HCR (%) HCR (%) India 70 40 30 40 30 20 20 10 10 0 1940 1950 1960 1970 1980 1990 2000 0 1990 2010 1995 Survey period Bangladesh 70 60 60 50 50 HCR (%) HCR(%) 2005 Survey period 70 40 30 Nepal 40 30 20 20 10 10 0 1980 2000 0 1985 1990 1995 2000 2005 2010 1995-1996 Survey period Survey period Rural Urban 2003-2004 Total Rural Total Urban 2010 Poverty trends trends Spatial Regional poverty • A major part of the poor lives in the eastern parts • Evidence of spatial clustering Districts Spatialtrends trends Poverty • Rural poor tends to live in clusters • Water and land factor in livelihood and food security • IGB is the hot bed of poor in South Asia Spatial and temporal trends in the Indian IGB Water poverty nexus-analytical framework Water for agriculture • Water poverty of exists when: – household is poor or incidence of poverty is high Land for agriculture WPLN Water for domestic purposes – agriculture play a major role in the rural livelihoods – access to a reliable water supply is a key factor in improving productivity Agriculture for livelihood and nutritional security Poverty trends Contribution of agriculture 1% of growth in agriculture GDP reduces poverty by 1.05% 70 y = 3132 x -1.05 R2 = 0.37 60 CH 50 Rural HCR (%) JH -1.19 y = 4398 x R2 = 0.59 40 BI JH MP BI 30 OR CH 20 GU 10 OR UP UT WB UT MP UP MH TN MH TN RJ WB GU RJ KE HR HP HP PU PU HR 0 0 50 100 150 Agriculture GDP/person (US$ in 2000 prices) Rural HCR - 1999/00 Rural HCR - 2004/05 200 250 How to unravel water land poverty nexus? • Use a Logit Regression model • LR estimate probability of a person being in poverty P 1 1 e ( X X i X j Z Z i Z j ) • P is the logistic cumulative probability function • P/(1-P) is the odds ratio of household being poverty • Combine household and survey data Data • Household consumption and expenditure survey data – NSSO 55th (1999/00) and 61st (2004/05) rounds – each has 30,000+ households in the IGB • District level aggregates of census data – Population census, agriculture census, annual agriculture at a glance publications, IWMI water and climate atlas – 280 districts in the IGB Data • Household level • – Cropped area per person – Average grain yields, – Irrigated area- % of cropped – Fruits and vegetable area – Rainfall area – Gross irrigated area – %GCA – Land tenure and holding size – % Groundwater irri. area – Socio-economic – Irrigated water productivity • HH SIZE – Marginal and small land holdings • Sex, religion, social class, education, dwelling type, • Access to electricity – Road density • Type of ration card • District level – Access to electricity 14 indicators • 13 indicators Results: Agriculture for rural livelihoods Results: Agriculture for rural livelihoods Low poverty in 2004/05 agricultur 1999/00 e operators Household employemnt Others Ag operator Self employed in non-ag.

Increase yields! – Increase rainfed yields, intensify irrigated agriculture. • Can water related interventions reduce poverty? – Substantially in the eastern IGB! – Irrigation matters, and reliability of irrigation is even more significant – Increase irrigated water productivity! • Can access to electricity reduce poverty? – Yes. Odds of poverty of those who do not have access to electricity is 2 to 1 – Increase access to electricity in the eastern IGB can result in better water use Conclusions • Land related interventions help – Large number of marginal and small sizes are the biggest constraint. – Land consolidation, where ever is possible, can contribute to productivity increase and poverty reduction. • Roads, electricity, education matters. • Non-farm employment have a significant impact. • Backward social classes and women headed households have higher poverty. Need thorough analysis of these groups. • Impacts of environmental factors needs to be included Thank you
