    The FAOSTAT domain Cropland Nutrient Balance disseminates nutrient flows in a given country and year. The cropland nutrient balance can give an indication of nutrient use efficiency, as it can help quantify excess nutrients leading to environmental risks, for instance, greenhouse gas emissions or pollution from volatilization and leaching/runoff. It can also signal cropland nutrient deficits that limit crop production. This brief analyses global, regional and country trends for the period 1961–2022.

    Of the essential material needs of humankind, the basic requirement is for an adequate supply of air, water and food. People have free access to the air they breathe. However, access to drinking-water and food, while easily obtained for some, is difficult for many. In addition to being physically available, these materials should also be of acceptable quality and continuously so. Hunger and diseases have affected humankind since the dawn of history. Throughout time, there have been p eriods of famine leading to suffering and starvation, making the fight against hunger and the diseases caused by malnutrition a permanent challenge. For many centuries until about 1800, the average grain yield was about 800 kg/ha, providing food only for a few people. The main problems were the low fertility of most soils (mainly caused by the depletion of nutrients) and the great yield losses from crop diseases and pests.

    Scaling soil nutrient balances
    Enabling mesolevel applications for African realities
    2004
    Also available in:

    Using data on three countries in sub-Saharan Africa, this report compares macro- and microlevel approaches to determine soil nutrient balances with an innovative mesolevel approach. It highlights the added value that a mesolevel approach can provide in terms of its usefulness to mesolevel stakeholders in articulating and targeting scale-specific soil fertility enhancing measures, and its validity as an entry point for policy-makers and privatesector intervention.
