A participatory stakeholder-based approach was employed to improve the quality of exportable fish and prawn landed in Kulierchar of Kishoregonj through reduction of the post harvest loss and its impacts were assessed. Primary data revealed that wet fish were minimally washed with clean water immediately after harvest. Ice boxes were not used in any stages from harvest to processing plants. Bamboo split baskets were mostly used to keep or carry fish. Landed fish were found to be dispersed on plastic mat or polythene paper kept on earthen floor of the wholesaler shed, called “Arat”. Icing of individual catch soon after harvest was very insignificant, ranging from 2 – 15 % only. Prawn were found to be iced during transport to landing center at little higher rate (32%), but most of the other fish were not significantly iced during transport to landing center. Primary awareness of the beneficiaries on quality deterioration of fish was assessed and the impacts of participatory awareness development tools (PRA and RRA, personal contacts, brain storming and awareness development training) on export, income, nutrition and improved handling of landed exportable prawn/fish were re-assessed. Efficacy of such measures to improve the situation were monitored for sixteen months. Awareness in terms of benefit of good practices was high in factory technicians. Other stakeholders had very shallow or poor knowledge on use of improved handling and processing of fish. Participatory tools employed in this study was found to be effective in developing awareness of stakeholders in different value chains of wet fish handling and distribution and reducing post-harvest loss.DOI:  http://dx.doi.org/10.3329/pa.v21i1-2.16757 Progress.

Agriculture is considered to be a vital aspect of Algeria’s national economy and rural development. Achieving sustainable agricultural production, generating employment, reducing imports and minimising post-harvest crops losses are the major objectives of the Algerian government. However, based on the evaluation of existing policies, this study found that poor governance is hampering the agriculture sector, particularly in terms of management of financial resources, where most financial investments are made only for short-term gains. The lack of awareness about the importance of post-harvest practices and lack of using modern technology threaten the growth of this sector. Adopting sound post-harvest methods can reduce food losses and wastage in every stage of the food supply chain, and integration of modern techniques, skilled labour, and education training systems are very important if agriculture in Algeria is to progress.

The consumer demand for fresh fruits and vegetables increases every year, and farmers need a low cost novel method to reduce post-harvest loss and preserve the quality of fresh fruits and vegetables. This study identifies a method to induce soil bacteria to biosynthesize a nitrile compound that potentially enters the plants tissue and negatively affects climacteric ripening and delays the ripening process at 20-30˚C. This study used soil rich with soil microbes, to delay the ripening of climacteric fruit. The soil was treated with nitrogen, a heavy metal, and ethylene gas. Ethylene induced the soil to delay the ripening of organic bananas and peaches. A prototype transportation container maintained fruit fresh for up to 72 h at 20-30˚C. The fruit retained color, firmness, texture, no bruising and minimal spotting. The soil also prevented fungal infection in all samples. GC-MS analysis suggests ethylene induced the soil microbes to release an acetonitrile compound into the gaseous environment. The nitrile is released in low concentrations, but mature plants (fruits) contain very low levels of indole-3-acetonitrile (IAN) or indole-3-acetic acid (IAA). The nitrile may obstruct or modify the mature plants (fruit) late stages development process, thus delay the climacteric ripening process and retarding the physiological and phenotypic effects of fruit ripening. We believe this study may have strong applications for post-harvest biotechnology.

Between 2013 and 2015 a large part of the western United States, including the Central Valley of California, sustained an extreme drought. The Central Valley is recognized as a region of hemispheric importance for waterbirds which use flooded agriculture and wetlands as habitat. Thus, the impact of drought on the distribution of surface water needed to be assessed to understand the effects on waterbird habitat availability. We used satellites to quantify the impact the recent extreme drought on the timing and extent of available waterbird habitat during the non-breeding season (July – May) by examining flooding in agriculture (rice, corn, and other crops) and managed wetlands across the Central Valley. We assessed the influence of habitat incentive programs, particularly The Nature Conservancy’s BirdReturns and the Natural Resources Conservation Service’s Waterbird Habitat Enhancement Program (WHEP), at offsetting waterbird habitat loss related to drought. Overall, we found significant declines in open water in post-harvest agriculture (20 – 80% declines) and in managed wetlands (47 – 59% declines) during the 2013 – 2015 drought compared to non-drought years 2000 – 2011. Crops associated with the San Joaquin Valley, specifically corn, as well as wetlands in that part of the Central Valley exhibited larger reductions in open water than rice and wetlands in the Sacramento Valley. However, seasonal wetlands on protected lands had a marginally significant (P<0.10) higher amount of open water in the drought years than those on non-protected lands. A large fraction of the daily open water in rice during certain times of the year, particularly in the fall for BirdReturns (64%) and the winter for WHEP (100%), may have been provided through incentive programs underscoring the contribution of these programs. However, further assessment is needed to know how much the incentive programs directly offset the impact of drought in post-harvest rice or simply supplemented funding for activities that might have been done regardless. Our, first of its kind, landscape analysis documents the significant impacts of the drought on freshwater wetland habitats in the Central Valley and highlights the value of using satellite data to track surface water and waterbird habitats. More research is needed to understand subsequent impacts on the freshwater dependent species that rely on these systems and how incentive programs can most strategically support vulnerable species during future drought.

Nanotechnology can contribute to food security in supply chains of agri production-consumption systems. The unique properties of nanoparticles have stimulated the increasing interest in their application as biosensing. Biosensing devices are designed for the biological recognition of events and signal transduction. Many types of nanoparticles can be used as biosensors, but gold nanoparticles have sparked most interest. In the work presented here, we will address the problem of fruit and vegetable decay and rotting during transportation and storage, which could be easily generalized also onto post-harvest loss prevention in general. During the process of rotting, different compounds, including different gasses, are released into the environment. The application of sensitive bionanosensors in the storage/transport containers can detect any changes due to fruit and vegetable decay and transduce the signal. The goal of this is to reduce the logistics cost for this items. Therefore, our approach requires a multidisciplinary and an interdisciplinary approach in science and technology. The cold supply chain is namely a science, a technology and a process which combines applied bio-nanotechnology, innovations in the industrial engineering of cooling processes including sensors for temperature and humidity measurements, transportation, and applied mathematics. It is a science, since it requires the understanding of chemical and biological processes linked to perishability and the systems theory which enables the developing of a theoretical framework for the control of systems with perturbed time-lags. Secondly, it is a technology developed in engineering which relies on the physical means to assure appropriate temperature conditions along the CSC and, thirdly, it is also a process, since a series of tasks must be performed to prepare, store, and transport the cargo as well as monitor the temperature and humidity of sensitive cargo and give proper feedback control, as it will be outlined in this chapter. Therefore, we shall discuss how to break the silos of separated knowledge to build an interdisciplinary and multidisciplinary science of post-harvest loss prevention. Considering the sensors as floating activity cells, modelled as floating nodes, in a graph of such a system, an extended Material Requirement Planning (MRP) theory will be described which will make it possible to determine the optimal feedback control in post-harvest loss prevention, based on bionanosensors. Therefore, we present also a model how to use nanotechnology from the packaging facility to the final retail. Any changes in time, distance, humidity or temperature in the chain could cause the Net Present Value (NPV) of the activities and their added value in the supply chain to be perturbed, as presented in the subchapter. In this chapter we give the answers to the questions, how to measure the effects of some perturbations in a supply chain on the stability of perishable agricultural goods in such systems and how nanotechnology can contribute with the appropriate packaging and control which preserves the required level of quality and quantity of the product at the final delivery. The presented model will not include multicriteria optimization but will stay at the NPV approach. But the annuity stream achieved by improved sensing and feedback control could be easily combined with environmental and medical/health criteria. An interdisciplinary perspective of industrial engineering and management demonstrates how the development of creative ideas born in separate research fields can be liaised into an innovative design of smart control devices and their installation in trucks and warehouses. These innovative technologies could contribute to an increase in the NPV of activities in the supply chains of perishable goods in general.
