Reduced food security

  • Objective
    Approach

    Traditional methods of food drying is to place the foodstuffs in the sun in the open air. This method, called sun drying, is effective for small amounts of food. The area needed for sun drying expands with food quantity and since the food is placed in the open air, it is easily contaminated. Therefore, one major reason why sun drying is not easily performed with larger quantities of food is that the monitoring and overview becomes increasingly more difficult with increasing food quantities.

    Both the natural values and economic values have increased in Nykvarn since the municipality restored the mercury-contaminated lake Turingen, The today ineadible fish will in a relatively near future be eadible again.

    Technology

    The presence of lead kills most bacteria making it impossible to bioremediate soil contaminated with lead. This bacterium is able t o survive and bioconcentrate lead on or in its membrane which probably allows it to survive as well as to remove lead from contaminated soils The use of a bacteria for on-site remediation of soils by accessing the soil to a bioreactor with encapsulated bacterium that can be separated later to the soils or using a membrane to immobilize the bacterium. This is a soil organism which will survive in the soil at pHs of soils (around 4).

    Background: Fresh produce has been associated with microbial outbreaks around the world thought to be caused in part by improper sanitation of fresh produce. Current disinfection methods rely on harsh chemicals which may alter the flavor of the fresh food or potentially cause an allergic reaction for some consumers. Furthermore the chemicals employed in sanitation may have a significant environmental impact. Technology Description: Researchers at the University of California Davis and Drexel University have developed a unique method for disinfecting produce.

    1. Dryer is a mechanism for drying the agriculture and marine products in order to increase the shelf life and maintain the quality of such products. Drying is the processes without causing damage to the quality of the interior and exterior of the safe storage moisture content typically from 14 to 15 percentage to refer to the process of removing the moisture. That is to say the operation of supplying the heat required for evaporation is supplied to room temperature or heated air to the processes and at the same time remove the evaporated moisture. 2.

    Description

    Agroecology is a holistic production method that works at the agroecosystem level. It is based on adopting integrated management for resource conservation as well as diversifying and enhancing synergies among the components of the agroecosystem, balancing energy and nutrient flows and adapting productive activities to local conditions. It promotes a high degree of interaction among its components to preserve biodiversity and attain sustainable production.

  • Objective

    Soil is a fundamental requirement for crop production as it provides plants with anchorage, water and nutrients. A certain supply of mineral and organic nutrient sources is present in soils, but these often have to be supplemented with external applications, or fertilisers, for better plant growth. Fertilisers enhance soil fertility and are applied to promote plant growth, improve crop yields and support agricultural intensification.

  • Objective

    Researchers at Purdue University have developed an instrument/software that allows remote sensing of surface soil moisture from an airborne instrument using reflective electromagnetic radiation. This can provide the most efficient method to collect measurements and survey an entire field with high spatial density in a short period of time. It makes use of lower-frequency signals which are required to penetrate the soil. Resolution is determined only by the frequency of the signal, under the assumption of a near-specular reflection, not the antenna size.
