  1. Sources of Agricultural Data Section B

  2. Administrative Records • Population or locality data files • Labor employment and unemployment offices • Taxation data • Farm registers

  3. Administrative Record Advantages • Reduced costs of data collection • Reduced respondent burden • Production of data on detailed domains • Estimating transition over time

  4. Administrative Record Cautions • Information can be outdated • Coverage may not be complete • Accuracy must be verified • Potential bias

  5. Sample Surveys • Agricultural surveys • Holding unit of enumeration from agricultural census • Household surveys • Individual and households are units of enumeration from population census

  6. Sample Surveys • Labor force surveys • Establishment is unit of enumeration including agricultural sub-sector • Economically active population is unit of enumeration – can be biased against subsistence agricultural workers

  7. Agricultural Surveys • Agro-economic surveys provide required data on agriculture activity and employment • Structural data gathered in first round of the year • Surveys can be targeted to focus on one crop, holding type or activity

  8. Agro-Economic Surveys • Data not captured: • Characteristics of holder’s household members • Activities of holder’s household members not working on holding • Structure of the holder’s household income

  9. Crop Survey Examples • Crop production survey: • Planting intentions prior to planting • Crop plantings after planting • Crop conditions before harvest • Crop production after harvest

  10. Crop Survey Examples • Survey of post-harvest losses • Survey of food stocks • Crop marketing survey

  11. Livestock Survey Examples • Surveys on livestock products and structure: • Milk and wool production • Livestock by breed, sex and number • Surveys of abattoirs, butchers, dairies • Marketing board information • Survey of feed stocks

  12. Other Agricultural Surveys • Farm management surveys • Organization and management of farms • Cost of production surveys • Operational costs for a particular activity • Time use surveys • Examines contributions by family members to agricultural holdings

  13. Household Surveys • Usually cover multiple topics, a few are specialized • Include all households, not just ones with agricultural holdings • Identification of households with enterprises, including agriculture, could guide administration of supplementary modules

  14. Household Surveys • Demographic and Health Survey (DHS) • Core Welfare Indicator Questionnaire (CWIQ) surveys • Living Standards Measurement Study (LSMS) surveys • Household Budget surveys • Education surveys • Labor Force surveys • Food security surveys

  15. Labor Force Survey • Household member characteristics • Activity status • Occupation, Industry and status in employment • Time worked – may be expanded to time use • Wages, salaries and income

  16. LSMS • Designed to assist decision makers design and monitor socioeconomic policies • Designed to improve household survey data and build statistical capacity • Has been conducted in over 40 countries since 1980 Source: Living Standards Measurement Study, The World Bank

  17. LSMS – ISA • Basic crop production, storage and sales • Productivity of main crops • Land holdings • Farming practices • Input use and technology adoption • Access to and use of services, infrastructure and natural resources • Livestock • Fishery Source: Living Standards Measurement Study, The World Bank

  18. Remote Sensing Technology • Satellite imagery can assist in the stratification of land area • Can be combined with GIS sample frame • Assist in crop area estimation • Dissemination of data using GIS

  19. Famine Early Warning System (FEWS) • A system that integrates market information, crop assessments and satellite data to identify areas at risk of food insecurity. • Objective is to provide data on areas of potential food insecurity in time for decision makers to act upon the information. • More information can be found at www.few.net

  20. Summary • Administrative records • Agricultural surveys • Crop, livestock, farm management, cost of production, and time use surveys • Household surveys • Labor force, LSMS • Remote sensing technology use

  21. Section B Quiz • What is the unit of enumeration for an agricultural survey? • Name two potential problems with administrative data. • What is the analytical advantage of collecting agricultural data in a household survey? • What does a post-harvest loss survey measure?
