Loss of productivity

  • Sectors
    Objective

    Fogs have the potential to provide an alternative source of fresh water in dry regions and can be harvested through the use of simple and low-cost collection systems. Captured water can then be used for agricultural irrigation and domestic use. Research suggests that fog collectors work best in locations with frequent fog periods, such as coastal areas where water can be harvested as fog moves inland driven by the wind.

  • 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).

    Technology

    Chemical contaminants such as nitrogenous wastes found in aquacultures or groundwater may contaminate nearby areas and drinking water supplies. Groundwater pollution may be caused by activities such as industrial waste disposal accidental spills fuel tank leakage or application of fertilizers herbicides or pesticides to crops. Natural causes such as arsenic also may result in groundwater contamination. Organisms are a major cause of water and aqueous environment contamination and are one of the world’s largest health concerns.

  • Objective

    The life cycle of higher plants consists of two major phases the vegetative phase and the reproductive (flowering) phase. In general plants store matter and energy in the form of carbohydrate reserves during the vegetative phase and then mobilize these reserves in the development of flowers fruit and seeds during the reproductive phase which is often triggered by various light- and circadian-related factors.

  • 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.

  • Sectors
    Objective

    Organic agriculture is a production system which avoids or largely excludes the use of synthetic fertilisers, pesticides and growth regulators. It can sequester carbon using crop rotations, crop residues, animal manure, legumes, green manure, and off-farm organic waste (Lampkin et al., 1999). It can also reduce carbon emissions by avoiding the use of fossil fuels used in the manufacture of the chemicals used to make synthetic materials.

  • Objective

    The introduction of new cultivated species and improved varieties of crop is a technology aimed at enhancing plant productivity, quality, health and nutritional value and/or building crop resilience to diseases, pest organisms and environmental stresses. Crop diversification refers to the addition of new crops or cropping systems to agricultural production on a particular farm taking into account the different returns from value-added crops with complementary marketing opportunities. Major driving forces for crop diversification include:

  • 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.

  • 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.
