Loess and PHW (post-harvest waste) are easily accessible in the Chinese Loess Plateau and have been widely applied to construction of residential houses that have been inhabited for decades under the effect of freeze-thaw cycles. Although many researchers have recognised that the addition of fibers to loess soil is effective in preventing soil erosion and stabilising slopes, a consensus on this claim has not been reached yet. This study investigates the shearing behaviour of the loess-PHW mixture using small-scale and large-scale direct shear (SSDS and LSDS) tests. Four typical shear stress versus horizontal displacement curves from the multiscale direct shear tests are recognised where one is featured with strain-softening shape and the other three with a strain-hardening shape. Two out of the three curves with strain-hardening shape show a gradual increase in the shear stress at additional and larger displacements, respectively, in which some factor starts to have an influence on the shearing behaviour. Comparisons of the shear strength measured in SSDS and LSDS are made, indicating that there are differences between SSDS and LSDS. The effect of PHW addition on shear strength is assessed in order to determine the optimal dosage. The improvement of shear strength is attributed to the effect of particle inter-locking, resulting from the addition of PHW to loess specimens, and takes effect as the water content surpassed a threshold, i.e., >14%, that facilitates particle rearrangement. Particle-box interaction behaviour is assessed at the same time, and the findings satisfactorily address the main cause of the gradual increase in shear stress following the curve inflection point. The improved shearing behaviour proves the ability of the loess-PHW mixture to resist the seepage force and consequently stratum erosion.

Despite its great potential as a food, feed and for industrial application, its processing and marketing remains economically unexploited. A cross-sectional baseline survey was undertaken in Western (Migori and Busia) and Coastal (Kilifi and Kwale) regions of Kenya between March 2013 and February 2014 using structured questionnaires to assess the post-harvest practices, opportunities and constraints in cassava processing. Results indicate that cassava processing is predominantly (58%) a women affair, males accounting for 42% with modal processors age being 32 years. Flour was the most common processed cassava product in the Coast (33%) while dried chips was highly produced in Migori and Busia in equal proportion of 43%. Other important products included cassava crisps and composite flour. Coast region had a greater diversity of products which are none existent in other regions. Most of the processing across the regions are small scale with workers mostly being the owners and activities take place in open yards with majority of these being in Busia (85 %) followed by Migori (67 %) and Coast region (57 %). Constraints during cassava processing were ranked in the following order: irregular and inadequate supply coupled with low seasonal demand for cassava and cassava products; high perishability of cassava roots; lack of value addition and processing tools; poor group dynamics, cohesion and management structure; lack of capacity building in production and processing technologies. There is very limited value addition to cassava in the study regions and hence the need to develop innovative technologies as well as new domestic and industrial products. Consumer sensitization and awareness on utilization of cassava and cassava products may be key to its promotion.

In Sri Lanka, 70% of 21 million population live in non-urban areas, and agriculture provides livelihood for approximately 40% of them. The agricultural marketing process in the country is a complex operation due to services and functions involved in moving a crop product from where it was produced to where it would finally be consumed. Further, with a wide range of agricultural crops being produced, post-harvest handling process create different degrees of quantitative and qualitative losses in a complex market chain, which are estimated at 20% to 40% for vegetables and 30% - 40% for fruits. Improper and non-scientific post-harvest practices and handling, gaps in integration of cold chain practices & elements with post-harvest process, and lack of knowledge & awareness on many related aspects at grass root farmer level etc. appear to contribute to losses that finally prevent due economic benefits reaching the small-scale producer. In order to increase the effectiveness of post-harvest process handling of fruit and vegetables, appropriate corrective measures targeting small scale producers as well as commercial scale producers need to be popularized and practiced. At small scale producer level, promotion of appropriate low-cost post-harvest practices and procedures, facilitating low-cost cold chain elements and user-friendly information flow mechanism on market situation would certainly help avoid some of the steps that lead to losses. Monitoring system of commercial post-harvest handling process that ensure scientific bulk handling, storage and transportation of fruit and vegetables, properly designed economic centers with well regulated environmentcontrolled storages etc. would greatly reduce loses in bulk handling, ensuring better food security in the island.

Fresh horticultural goods often require drying post-harvest to preserve quality and allow for successful long-term storage of plant material. Given the influx of hops cultivation in the state of Florida, this 5-page publication will help Florida hops growers and hobby brewers to understand how to efficiently dry hops prior to storage.
