Reduce GHG emissions

Reduce GHG emissions

  • Conservation tillage

    Type: 
    Technology
    Objective:

    Conventional tillage is the traditional method of farming in which soil is prepared for planting by completely inverting it with a tractor-pulled plough, followed by subsequent additional tillage to smooth the soil surface for crop cultivation. In contrast, conservation tillage is a tillage system that conserves soil, water and energy resources through the reduction of tillage intensity and retention of crop residue. Conservation tillage involves the planting, growing and harvesting of crops with limited disturbance to the soil surface.

  • Nutrient management: nitrogenous fertilisers

    Type: 
    Technology
    Objective:

    Efficient use of nitrogenous fertilisers can reduce N2O emissions from agricultural fields. In addition, by reducing the quantity of synthetic fertilisers required, improved management can also reduce CO2 emissions associated with their manufacture. In this article a variety of fertiliser management technologies are discussed in brief, followed by a discussion on their relative advantages and disadvantages.

  • Crop rotation

    Type: 
    Technology
    Objective:

    Description

    Crop rotation consists in sequentially producing plant species in a given location by alternating crops every year, every two years or every three years. This diversified production system prevents the build-up of pests and diseases as well as the exhaustion of the soil that usually occur with production of a single crop (or crops of a single family) in successive agricultural cycles.

  • Ex situ conservation and seed banks

    Type: 
    Technology
    Objective:

    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.

  • Iron Nutrient Particles to Seed Algae (Phytoplankton) Growth

    Type: 
    Product
    Objective:

    Background: Algae are responsible for converting carbon dioxide into oxygen. However more than 20% of the world\\\'s oceans lack algae growth. The essential nutrient that is lacking in the algae-deficient surface waters is iron. However this iron must be (i) on the surface so that the algae can convert carbon dioxide to oxygen via photosynthesis and (ii) biologically available so that algae can use it. Technology Description: This technology describes the composition of and the method of production for water-buoyant particles that contain bioavailable iron.

  • Carbon-negative nanoparticle production

    Type: 
    Product
    Objective:

    Carbon Upcycling Technologies is at an early stage of developing a process that sequesters carbon from CO2 in the form of a modified graphene product. The process itself requires a concentrated CO2 stream(such as the waste gas from coal fired power generation facilities refineries and other processing plants)as well as another solid carbon feedstock such as graphite or coal. Active carbon sites are generated on the solid carbon feedstock by repeatedly breaking molecular bonds on the solid. The active carbon reacts with the gaseous CO2 molecule.

  • Climate Friendly Childbirths

    Type: 
    Product
    Objective:

    Nitrous oxide is used during 80 per cent of childbirths. This gas is a green-house gas 310 times stronger than carbon-dioxide and one kilogram that is emitted into the atmosphere is equivalent to 1500 kilometres of driving a car. Region Skåne, the regional health care management organization of southern Sweden has installed equipment from the company Nordic Gas Cleaning for separating the nitrous oxide into oxygen and nitrogen at all of its five hospitals with birth clinics. This has not only reduced emissions by 99 per cent.

  • Integrated nutrient management

    Type: 
    Technology
    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.
