Grain drying has become increasingly challenging for the Bangladesh food system as postharvest innovations have not kept pace with production growth and an increasing volume of grain is harvested during wet or foggy periods, when conventional open-air drying is problematic. This activity sought to build capacity for mechanical dryer service provision by small-scale entrepreneurs and to demonstrate a model for providing mobile grain drying services through entrepreneurs using a locally manufactured small-scale dryer. In coordination with Ministry of Food officials, the project selected 20 farmers to train as mechanized drying service providers, provided them with use of small-scale mobile bat...
Unprecedented growth in rice production in Bangladesh over the last four decades has outpaced the capacity of post-harvest operations, resulting in substantial grain losses. While production technology has changed dramatically over time, there has been relatively little private investment in transforming storage capacity in the country. This paper explores the lack of widespread private investment in improved grain storage and examines the potential for public support to stimulate greater private sector investment in modern storage. We calculate the returns to investment in bulk grain silos and hermetic cocoons that could upgrade warehouse storage, and calculate the grain loss that conversio...
Unprecedented growth in rice production in Bangladesh over the last four decades has outpaced the capacity of post-harvest operations, resulting in substantial grain losses. While production technology has changed dramatically over time, there has been relatively little private investment in transforming storage capacity in the country. This paper explores the lack of widespread private investment in improved grain storage and examines the potential for public support to stimulate greater private sector investment in modern storage. We calculate the returns to investment in bulk grain silos and hermetic cocoons that could upgrade warehouse storage, and calculate the grain loss that conversion to those technologies would prevent. We then assess the public support that would be required to trigger private investment in modern storage systems.
Warehouse receipts systems (WRS) have been used to tackle multiple challenges faced by farmers. In the absence of adequate collateral and consequent credit constraints, a WRS enables the use of inventory as collateral for loans, thus removing a key constraint farmers face. With growing digital reach, electronic based Negotiable Warehouse Receipts (e-NWR) that can be swapped, exchanged and traded and can assist in deepening financial markets while maintaining the integrity of the system. While e-NWRS can potentially address farmer level constraints, they can also be viewed from a larger policy perspective as a system that aids government plans for food security and manage public procurement o...
A Century of Innovation: The Engineering that Transformed Our Lives is a full-color coffee table book that details the greatest achievements of 20th-century engineering. Each chapter details one specific engineering "feat" with a discussion of the discovery's impact on society and descriptions and illustrations of how that discovery "works."
This review attempts to synthesize the findings of the growing peer-reviewed literature on bioslurry to provide a sound and scientific basis for bioslurry use. At the same time, it sets out to identify the various research gaps related to bioslurry.
Waste Biorefinery: Integrating Biorefineries for Waste Valorisation provides the various options available for several renewable waste streams. The book includes scientific and technical information pertaining to the most advanced and innovative processing technologies used for the conversion of biogenic waste to biofuels, energy products and biochemicals. In addition, the book reports on recent developments and new achievements in the field of biochemical and thermo-chemical methods and the necessities and potential generated by different kinds of biomass in presumably more decentralized biorefineries. The book presents an assortment of case-studies from developing and developed countries p...
This framework presents ten interrelated principles/elements to guide Sustainable Agricultural Mechanization in Africa (SAMA). Further, it presents the technical issues to be considered under SAMA and the options to be analysed at the country and sub regional levels. The ten key elements required in a framework for SAMA are as follows: The analysis in the framework calls for a specific approach, involving learning from other parts of the world where significant transformation of the agricultural mechanization sector has already occurred within a three-to-four decade time frame, and developing policies and programmes to realize Africa’s aspirations of Zero Hunger by 2025. This approach entails the identification and prioritization of relevant and interrelated elements to help countries develop strategies and practical development plans that create synergies in line with their agricultural transformation plans. Given the unique characteristics of each country and the diverse needs of Africa due to the ecological heterogeneity and the wide range of farm sizes, the framework avoids being prescriptive.
