    Rooftop water collection, drip irrigation and plastic mulching in home garden conditions in drought prone areas of Cambodia 2017
    Also available in:
    No results found.

    The impact of natural hazards on the agriculture sector can be devastating. To reduce the effects of climate change, farmers use strategies to counter effect the influence of a natural disaster. For example saving rooftop rainwater can help during draught, and mulching help maintain soil moisture. In this good practice, first, steps and requirements for rainwater collection are explained. Building on water harvesting, drip irrigation system is explained which is crucial for water saving during irrigation in the dry seasons. Third, mulching methods are described. Mulching is a technique that is used to cover and to keep soil moisture for a better plant growth, and finally a cost-benefit analysis of their combined application is presented.

    Wheat cultivation with farmyard manure and compost application under dry spell conditions in Pakistan 2018
    Also available in:
    No results found.

    This technology describes the introduction of farmyard manure (FYM) and the application of compost for wheat production in the Ghotki district in Pakistan. FYM serves as balanced nutritional manure for plants, improves soil biodiversity and represents a cost-effective fertilisation strategy. Physical properties like bulk density, porosity, void ratio, water permeability and hydraulic conductivity were also significantly improved when FYM was applied. Similarly, compost application increases the availability of essential micro- and macronutrients for the crop and can improve physical and chemical properties of the soils. The tiller, plant height and biomass were also significantly increased. Using compost and FYM helped farmers to increase yields, while contributing to decrease the use of chemical fertilizer and improving soil texture for successive crops.

    Climate change and food security: risks and responses 2015
    Also available in:

    End hunger, achieve food security and improve nutrition are at the heart of the sustainable development goals. The World has committed to eradicate extreme poverty and hunger by 2030. But climate change is undermining the livelihoods and food security of the rural poor, who constitute almost 80 percent of the world’s poor. The effects of climate change on our ecosystems are already severe and widespread. Climate change brings a cascade of impacts from agroecosystems to livelihoods. Climate change impacts directly agroecosystems, which in turn has a potential impact on agricultural production, which drives economic and social impacts, which impact livelihoods. In other words, impacts translate from climate to the environment, to the productive sphere, to economic and social dimensions. Therefore, ensuring food security in the face of climate change is among the most daunting challenges facing humankind. Action is urgently needed now to reduce vulnerability and increase resilience of food systems to ensure food security and good nutrition for all.

    The future of food and agriculture – Alternative pathways to 2050 2018
    Also available in:
    No results found.

    The report 'The future of food and agriculture – Alternative pathways to 2050' explores three different scenarios for the future of food and agriculture, based on alternative trends for key drivers, such as income growth and distribution, population growth, technical progress in agriculture, and climate change. Building on the report 'The future of food and agriculture – Trends and challenges', this publication provides scenario-based quantitative projections to 2050 for food and agriculture. Quantitative evidence and qualitative assessments, shed light on possible strategic options for achieving the Sustainable Development Goals of eradicating hunger, improving nutrition and ensuring that food and agricultural sectors become economically, socially and environmentally sustainable.
