Synopsis (short abstract) This technical report provides findings of field test conducted in identified states/districts/ municipalities/study area in Mexico on the basis of sampling methodology for estimation of post-harvest losses of horticultural crops (fruits and vegetables) developed by the team led by Dr. Tauqueer Ahmad, Head, Division of Sample Surveys, Indian Agricultural Statistics Research Institute, Institute of Indian Council of Agricultural Research (ICAR-IASRI) ICAR-IASRI, New Delhi, India. The Technical Report entitled “Findings from the field test conducted on estimating post-harvest losses of fruits and vegetables in Mexico” contains details of findings of the developed methodology implemented in Mexico, including challenges encountered and lessons learnt. It is expected that this report will help the users from different countries in designing surveys for measurement of post-harvest losses of horticultural crops (fruits and vegetables).

Estimation of maize harvest and post-harvest losses in Zimbabwe. Field test report
2020

In the framework of the Global strategy to improve agriculture and rural statistics (GSARS), FAO provided technical assistance to Zimbabwe on the measurement of harvest and post-harvest losses through sample surveys. The technical assistance was provided in the form of a pilot study on estimating harvest and post-harvest losses for major crops in the Makonde district in the communal and A1 farming sectors. The survey focused on maize and sorghum and included the measurement of on-farm losses. The survey captured losses through interviews of farmers as well as through physical measurements. The number of usable data points for sorghum were too few to provide reliable production and loss estimates, hence the results presented in this report mostly refer to maize. The results show that 5.2 percent of grain is lost at harvest and 3.8 percent lost at drying. The comparison of the loss estimates according to the measurement method used shows mixed results; in A1 farming sectors, farmers’ own loss estimates tend to be lower than physical measurement, while the opposite is evidenced in the communal sector (except for drying). Timely harvesting was used by most farmers to limit losses, followed by stoking when harvesting and the use of chemicals to protect crops from pest infestations during storage.

Case studies on managing quality, assuring safety and reducing post-harvest losses in fruit and vegetable supply chains in South Asian countries 2018

Also available in:

Fresh fruits and vegetables contribute significantly to food and nutrition security, poverty reduction and to economic development in the countries belonging to the South Asian Association for Regional Cooperation (SAARC). Smallholders who make little use of post-harvest (PH) technologies produce most of the fresh fruits and vegetables supplied to mass markets in the Region. The high qualitative and quantitative PH losses sustained in these traditional fruit and vegetable supply chains negatively impact all stakeholders in the supply chain, with farmers and retailers being the most affected. To address these issues, technical innovations and good practices were introduced through pilot demonstrations and training in six fresh produce supply chains in three South Asian countries: The People’s Republic of Bangladesh, The Federal Democratic Republic of Nepal and The Democratic Socialist Republic of Sri Lanka. The findings documented in this publication provide an evidence base for the cost-effective management of the quality of fresh produce and the reduction of quantitative loss in fresh horticultural supply chains in SAARC countries.
