Improved cultivation techniques

Improved cultivation techniques

  • Moist Membranes for Cultivation and Collection of Algae

    Type: 
    Product

    Background: Mass cultivation of algae for biofuel production has focused on the use of open ponds or closed bioreactors. Both approaches depend upon routine liquid culturing of the algae and require the removal of large quantities of water at the time of cell harvesting and subsequent extraction of desired products. This invention proposes the use of porous inert membranes to support the growth and subsequent harvesting of the algae.

  • Co2 Bio-Mitigation using Microalgae

    Type: 
    Technology
    Objective:

    What is Micro-algae

    Micro-algae are a group of unicellular or simple multicellular fast growing photosynthetic microorganisms that can conserve CO2 efficiently from different sources, including the atmosphere, industrial exhaust gases, and soluble carbonate salts. Micro-algae act as a major system for converting atmospheric CO2 into lipids under sunlight and increase the output of algal oil. The enzyme acetyl Co-A carboxylase (ACCase) from micro-algae catalyzes the key metabolic step in the synthesis of oil in algae.

  • Good farming practices to save river Kagera from silting

    Type: 
    Publication
    Publication date:
    Objective:
    Sectors:

    Description of the project: The Kagera river, a tributary of the Nile, is being threatened by silting due to unsustainable farming methods. Its river basin is a very rich agricultural ground supporting 16.5 million people in Burundi, Rwanda, Tanzania and Uganda. The project aims to improve and modernize current farming  methods, in order to improve food security and ensure resilient livelihoods for people and animals living in this area. Groups of  50 new beneficiaries are trained every month on farming methods, followed by a tree-planting scheme by the river.

  • 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.

  • Floating agricultural systems

    Type: 
    Technology
    Sectors:
    Objective:
    Approach:

    Floating agriculture is a way of utilising areas which are waterlogged for long periods of time in the production of food. The technology is mainly aimed at adapting to more regular or prolonged flooding.

    The approach employs beds of rotting vegetation, which act as compost for crop growth. These beds are able to float on the surface of the water, thus creating areas of land suitable for agriculture within waterlogged regions. Scientifically, floating agriculture may be referred to as hydroponics. In Bangladesh, it has regional names such as baira, geto, dhap and bed.

  • Greenhouse crop management

    Type: 
    Technology
    Objective:

    Description

    A greenhouse is a closed structure, covered with translucent materials, that creates optimal climate, water, pest control, soil fertility and ventilation conditions in order to attain high productivity more quickly, at lower cost and with less of an environmental impact. Climate variables inside the greenhouse are controlled with several devices and materials including, inter alia, shade mesh, windows and openings, forced ventilation and humidifiers.

  • Adverse impacts of climate change on development of Bhutan: integrating adaptation into policies and activities

    Type: 
    Publication
    Publication date:
    Objective:
    Approach:

    Bhutan is a mountainous landlocked country with a varying climate and rich biodiversity. Despite significant economic progress being made over recent years Bhutan remains a least developed nation with constraints and vulnerabilities adversely affecting its capacity to cope with climate change.The authors recognise that Bhutan’s vulnerability is heightened by low economic strength, inadequate infrastructure, lack of institutional capacity and an agro-based rural economy. Impacts of climate change will have significant implications for the overall development of Bhutan.
