1. Sourcing Secondary Data for Cost Benefit Analysis Jonathan Bower Land Resources Division Secretariat of the Pacific Community

2. The word data is the plural of datum which is the past participle of the Latin dare, "to give", hence "something given".

3. Contents 1.Why secondary data? – Why secondary data is usually necessary for a CBA 2.What secondary data? – Sources of secondary data 3.Who has secondary data? – Useful contacts and general links

4. 1. WHY SECONDARY DATA? Why secondary data is usually necessary for a CBA

5. Localised primary data sources are not always enough to know the full costs and benefits of climate change, especially for CBAs of projects with a regional or national effect. Why use secondary data in a CBA?

6. Primary and secondary data need to be brought together to gain a fuller picture – E.g. digging a large drain to stop flooding enabled 1500 extra tonnes of sugar cane to be harvested (primary data) for the same price, but I needed to know the price of sugar cane per tonne (secondary data from Fiji Sugar Corporation) so I could work out the benefit of investing in the ditch. In the Excel example yesterday, we needed secondary data on: – grain imports – grain price – probability of biological hazard occurring Why use secondary data in a CBA?

7. 2. WHAT SECONDARY DATA Sources of secondary data

8. What secondary data might be needed? Climate change likely to affects agricultural production so we are likely looking at positive changes in crop yield or livestock production due to adaptation measures. Existing yields, prices, revenues Household level: Average rural household income and % of income from agriculture – to know how big a difference the adaptation measures are making. National level: GDP contribution of agriculture Probability of negative climate event Adaptation will also affect production costs – which can be found from both primary and secondary sources

9. Data Source Source: Steve Rogers, FAO (2010) What secondary data might be needed for a CBA?

10. Household Income and Expenditure Survey Does what it says on the tin, in detail. Data on consumption of and income from food-related goods – crops, livestock, fish You can ask for HIES data, not just the HIES report – Contact the national bureau of statistics, or if in doubt, contact Gerald Haberkorn, Manager of SPC’s Statistics for Development Program – geraldh@spc.int geraldh@spc.int WHY? Useful for: showing what proportion of household income comes from agricultural products showing household income and income per capita, disaggregated by region showing population of specific areas

12. Domestic Market Surveys Available from national statistics offices or departments of agriculture; used to calculate national accounts Useful for: – Prices of specific goods, predicting those prices in future – Quantity of goods: a measure of the size of the food market, predicting the size of this market in future – Estimating potential loss of domestic market revenue from climate change and/or gain from an intervention such as introduction of salt-resistant taro

13. Domestic Market Surveys Solomon Islands: no domestic market survey but: Market analysis of fresh vegetables in Solomon Islands (World Vegetable Center 2009) http://203.64.245.61/fulltext_pdf/EB/2001-2010/eb0138.pdf http://203.64.245.61/fulltext_pdf/EB/2001-2010/eb0138.pdf Fiji – available from 29 July 2010 to present http://www.agriculture.org.fj/index.cfm?si=main.resources&cmd=forumview&cbegin=0&uid=mrktinfocrop&cid=1638

14. Consumer Price Index An index constructed from the increase in price of a weighted basket of goods that the average consumer buys Describes the rate at which price increases each year WHY? Some costs and benefits come in nominal terms, so to convert them to real terms we need to guess what rate of inflation to use. In simpler cases this may not be needed Export Price Indices
