    Content: Maintaining permanent coverage of the soil using crop residues is an important and commonly recommended practice in conservation agriculture. Measuring this practice is an essential step in improving knowledge about the adoption and impact of conservation agriculture. Different data collection methods can be implemented to capture the field level crop residue coverage for a given plot, each with its own implications for the survey budget, implementation speed, and respondent and interviewer burden. This study tests six alternative methods of crop residue coverage measurement among the same sample of rural households in Ethiopia. The relative accuracy of these methods is compared against a benchmark, the line-transect method. The alternative methods compared against the benchmark include: (i) interviewee (respondent) estimation; (ii) enumerator estimation visiting the field; (iii) interviewee with visual-aid without visiting the field; (iv) enumerator with visual-aid visiting the field; (v) field picture collected with a drone and analyzed with image-processing methods; and (vi) satellite picture of the field analyzed with remote sensing methods. Results of the methodological experiment show that survey-based methods tend to underestimate field residue cover. When quantitative data on cover are needed, the best estimates are provided by visual-aid protocols. For categorical analysis (such as greater than 30 percent cover or not), visual-aid protocols and remote sensing methods perform equally well. Among survey-based methods, the strongest correlates of measurement errors are total farm size, field size, distance, and slope. The results deliver a ranking of measurement options that can inform survey practitioners and researchers.

    Disaggregated Survey Data on Taxation to Improve Policy Design : A Perspective from the Ethiopia Socioeconomic Survey (2018/19) (2021)

    Content: A disaggregated analysis of the tax burdens and economic needs of the most economically vulnerable - such as poor women and men, informal workers, and owners of micro- and small enterprises - is crucial for designing equitable and well-targeted tax and public spending policies. This is particularly important in low-income countries, where formal and informal tax systems often exist in parallel, and administrative data is sparse. Availability of data on tax payments by households and non-farm enterprises, individual-level employment and asset ownership, and contributions to community institutions and infrastructure programs can reveal important distributional implications for tax policy design going forward. This survey brief summarizes findings from the tax module of the nationally representative 2018-19 Ethiopia socioeconomic survey (ESS). The tax module covers different types of formal and informal taxes that households, businesses, and individuals pay, as well as informal contributions towards services and infrastructural improvements in the community. Findings from the multi-topic survey also reveal different tax burdens by socioeconomic and demographic groups, as well as across rural and urban areas, that are important for national tax policy design and targeting
