  • Biodigester

    Type: 
    Technology
    Sectors:
    Objective:

    What are biodigesters?

    A biodigester system utilizes organic waste, particularly animal and human excreta, to produce fertilizer and biogas. A biodigester consists of an airtight, high-density polyethylene container within which excreta diluted in water flow continuously and are fermented by microorganisms present in the waste. The fermentation process is anaerobic, i.e., it takes place without oxygen, and the bacteria responsible for decomposition are methanogenic (i.e., they produce methane, also known as biogas).

  • Direct seeding (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    Pre-germinated seeds or seedlings are directly planted in soil or broadcast in flooded field under this technology. Rice cultivation is responsible for 10% of GHG emissions from agriculture. In developing countries, the share of rice in GHG emissions from agriculture is even higher, e.g., it was 16% in 1994.

  • Rainwater harvesting

    Type: 
    Technology
    Sectors:
    Objective:

    Rainfall can provide some of the cleanest naturally occurring water that is available. There is considerable scope for the collection of rainwater when it falls, before huge losses occur due to evaporation, transpiration, and runoff and drainage - before it becomes contaminated by natural means or man-made activities. Rainwater harvesting is a particularly suitable technology for areas where there is no surface water, or where groundwater is deep or inaccessible due to hard ground conditions, or where it is too salty or acidic.

  • 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.

  • Engineered Rice Plants for Enhanced Resistance and Decreased Uptake of Toxic Metalloid Arsenic

    Objective:
    Technology:

    Background

    Climate changes have made agriculture a difficult proposition for small farmers in rain-fed and marginal lands while available arable land is decreasing every year. Agricultural crops and vegetables that can thrive in conditions of drought high salinity high-temperature or heavy metal contamination will go a long way in addressing the world’s food needs.
