Post-harvest technology transfer to reduce on farm grain losses in Kitui district, Kenya

Training and demonstrations on post harvest technology transfer to reduce grain losses at farm level were conducted in five divisions of Kitui district with the overall objective of consolidating what the farmers already knew about storage. It was also to assist them select appropriate storage methods with emphasis on proper application of pest control products. A total of 163 participants were trained in storage pest management covering pest infestation cycle, use of chemical and non-chemical methods of control, storage practices and identification of major pests using specimen and pictures, dangers of mycotoxins on maize followed by on demonstrations.Farmers demonstrated traditional practices of determining grain moisture content, and shovel mixing, both on the tarpaulin and wheelbarrows. Sticks were other tools used to mix chemical dust with grain on tarpaulins and in the bags. The research team from Kenya Agricultural Research Institute (KARI) demonstrated proper use of the shovel and the “fuffle”, a device that is faster and more efficient in mixing grain with chemical dusts.Treated grain and a control were stored on site in 90-kg bags. Evaluation, based on the level of damage and live infestation was done after 3 months. Despite anomalies like lack of uniformity of grain in different bags depending on source, KARI methods appeared better than farmers’ methods in most instances. Farmers were able to make informed decisions based on the mixing methods which gave better results. The fuffle was an effective tool for mixing grain with chemical dusts and farmers were keen to have it fabricated by local artisans. Farmers appreciated the training and demonstration and promised to adopt proper grain preservation techniques as demonstrated to improve grain quality.Keywords: Post harvest, Technology transfer, Grain losses, Farmer

Forming a Community of Practice to Support Faculty in Implementing Course-Based Undergraduate Research Experiences

There is an urgent need to influence educational change in the methods by which science is taught. Numerous national agencies have called for science, technology, engineering, and mathematics (STEM) educational reform with recommendations to address retention and increase diversity of students in STEM disciplines. One way to address these recommendations is by replacing the widespread traditional approach to foundational laboratory courses with course-based undergraduate research experiences (CUREs). As a creative alternative to one-on-one research mentorships, CUREs scale up the research experience to reach a greater number of students, many of whom would otherwise not be able to participate in research. Increasing the adoption of CUREs in foundational chemistry laboratory courses exposes a larger, more diverse population of STEM students to research experiences. The greatest impact of these experiences occurs in populations that are traditionally underrepresented in STEM disciplines, whose college experiences are enhanced by being a part of a diverse community. A Community of Practice brings together people with a common interest or goal. This chapter describes our steps to form a Community of Practice comprised of faculty from Primarily Undergraduate Institutions, community colleges, and high schools with the goal of providing a supportive framework that lowers barriers to CURE development and implementation for faculty in foundational chemistry laboratories
