DocumentIs Dirt Cheap? The Economic Costs of Failing to Meet Soil Health Requirements on Smallholder Farms
Agricultural productivity is hindered in smallholder farming systems due to several factors, including farmers’ inability to meet crop-specific soil requirements. This paper focuses on soil suitability for maize production and creates multidimensional soil suitability profiles of smallholder maize plots in Uganda, while quantifying forgone production due to cultivation on less-than-suitable land and identifying groups of farmers that are disproportionately impacted.

DocumentNon-Labor Input Quality and Small Farms in Sub-Saharan Africa: A Review
Adoption of non-labor agricultural inputs, including pesticides and mineral fertilizers, remains low among small-scale farmers in many low-income countries. Accurate measurement of the quality of these inputs and of quantities deployed is essential for assessing economic returns, understanding the drivers of agricultural productivity, and proposing and evaluating policies for increasing agricultural production. This paper reviews the evidence regarding the quality of mineral fertilizer and pesticides, inclusive of herbicides, available in local markets in Sub-Saharan Africa.

DocumentMeasuring Disaster Crop Production Losses Using Survey Microdata: Evidence from Sub-Saharan Africa
This paper exploits plot-level panel data for almost 20,000 plots on 8,000 farms in three Sub-Saharan African countries with information on harvest, input use, and different proxies of losses; household and community-level data; as well data from other sources such as crop cutting and survey experiments, to provide new insights into the reliability of survey-based crop loss estimates and their attribution to disasters.

DocumentNonclassical Measurement Error and Farmers’ Response to Information Reveal Behavioral Anomalies
This paper reports on a randomized experiment conducted among Malawian agricultural households to study nonclassical measurement error in self-reported plot area and farmers’ responses to new information that was provided to correct nonclassical measurement.

DocumentSurvey Measurement Errors and the Assessment of the Relationship between Yields and Inputs in Smallholder Farming Systems: Evidence from Mali
This working paper leverages unique survey data from Mali to demonstrate that self-reported crop yields, vis-a-vis (objective) crop cut yields, are subject to non-classical measurement error that biases the estimated returns to inputs, including land, labor, fertilizer, and seeds.

DocumentResearch on the Measurement of Post-Harvest Losses: Minimum losses by commodity and region
Information on minimum losses can help provide a benchmark for farm management, formulation of policies and investment decisions. This study connects this information to farming practices and production technologies, which can also help assess the effectiveness of loss reduction practices and the underlying policies and incentives that promote them.
