    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).

  • Rainwater harvesting

    Sectors
    Water
    Objective
    Adaptation

    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.

  • Direct seeding (rice)

    Agriculture
    Objective
    Mitigation

    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.

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

    Mitigation
    Technology
    Food

    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.

  • Hybrid rice variety

    Objective
    Mitigation

    Functions and use

    Hybrid rice variety offers high yield good adaptability and resistance to pests and can increase yield to over 20 percent more than that of conventional rice. Hybrid rice variety supporting plantation technology can improve both yield and efficiency.

  • Rainwater harvesting ex situ

    Sectors
    Water
    Objective
    Adaptation

    Most precipitation that falls on human settlements is lost to the atmosphere through evapo-transporation (evaporation plus transpiration of water taken up by plants), or runs into rivers away from settlements before it can be used. In some water-rich regions, particularly wealthy regions with centralized water infrastructure, these losses may not be a major concern. However, in many water-poor areas, small-scale collection infrastructure can contribute greatly to the volume of freshwater available for human use.
