1. Productivity growth and poverty reduction in India: A GEOSHARE application from the IRRI/Asia Hub Andy Nelson, Uris Baldos, Parvesh K. Chandna and Tom Hertel Wed 10 th Sep, 2014

2. Research questions 1.What is the current best information on agricultural productivity and poverty in India? 2.Case study: Has increased productivity led to a reduction in rural poverty in India?

3. Getting hold of the best available data  District level data for 20 major crops for 2005.  Good spatial detail! Contribution to better global datasets like SPAM and MIRCA  State level data on area and production for 20 major crops for 1993, 2000, 2005 and 2010.  State level data on cost of cultivation for major crops for 1993, 2000, 2005 and 2010.  State level data on agricultural and non-agricultural wages for 1993, 2000, 2005 and 2010.  Consistent poverty data at state level: 1993/4, 2004/5, 2009/10.  Good temporal data! Assessment of the relationship between poverty and agricultural growth based on Total Factor Productivity analysis

8. Changes in rural and urban poverty in India Poverty reduction over time. Rural poverty fell from 50% to 34%, urban from 32% to 21% Some states show evidence of stubbornly high poverty rates. An overall divergence in poverty reduction in recent years.

9. Has increased productivity led to a reduction in rural poverty in India?  Agriculture is a major component of India’s GDP and a source of economic growth;14% but reducing.  The agricultural sector is still the single largest employer and continued growth will directly impact rural livelihoods.  Growth in staples seems to have increased recently.  Evidence of a move from staple crops to high value crops.  Despite impressive poverty reduction, India is home to 1/3 rd of the world’s poor; 396m people (World Bank, 2014) more than any other country.  Are changes in agricultural productivity reducing poverty?

10. Growth in productivity is not just about yields  Total factor productivity (TFP) provides a broader concept of agricultural productivity than measures that compare output to just one input, like land (i.e. yield)  To estimate TFP, we need data on land, labour, capital, and material inputs used in agriculture and compare growth those inputs with growth in output of crop and livestock.  If total output grows faster than total inputs, total factor productivity ("factor" = input) has improved.  TFP, therefore, encompasses the average productivity of all inputs employed in the production of all crop and livestock commodities. TFP is the output considering all inputs. Source: Fuglie (2013) International Agricultural Productivity http://www.ers.usda.gov/data-products/international-agricultural-productivity.aspx

11. Source: Fuglie (2013) International Agricultural Productivity http://www.ers.usda.gov/data-products/international-agricultural-productivity.aspx Total Factor Productivity (All Ag. Inputs) vs. Partial Factor Productivity (Ag. Land) Graph shows a divergence in the annual average growth rate in agricultural land productivity (output per hectare) and TFP (output given all inputs). Particularly, prior to the 1990s TFP growth is slower than agricultural land productivity.

12. Has increased productivity led to a reduction in rural poverty in India? Evidence suggest that growth in Agricultural Total Factor Productivity – a measure of output given all inputs - leads to poverty reduction in developing regions (Fan, Hazell & Thorat, 2002; Thirtle, Lin & Piesse, 2003) Recent reduction in poverty incidence coincide with crop TFP growth in India Average annual growth of crop TFP (2004-05 to 2009-10) Total change in poverty incidence (2004-05 to 2009-10)

13. Strong TFP growth + reduction in poverty incidence is more evident in rural areas Average annual growth of crop TFP (2004-05 to 2009-10) States with growth in crop TFP also show a reduction in rural poverty incidence

14. However, reduction in poverty incidence hinges on Agricultural TFP growth not just Crop TFP growth Patterns are diverging in some states. Need TFP estimates for agriculture (Crops + Livestock) to formally analyze TFP and poverty incidence reduction Average annual growth of crop TFP (1999-00 to 2004-05) Average annual growth of agricultural TFP (1999-00 to 2004-05)

15. Key Messages  We still need more complete data on ALL agricultural activities as well as consistent time series on poverty in order to determine causal relationships.  Access to data is improving but much more to be done.  Heterogeneous patterns of poverty and crop TFP growth in India – great variation across states.  Correlation between states with higher crop TFP growth and greater poverty reduction.  TFP growth in staple crops and all agriculture have been diverging in some states.
