  • Soil carbon management in large-scale Earth system modelling: implications for crop yields and nitrogen leaching

    Type: 
    Publication
    Publication date:
    Objective:

    Results demonstrate that the effects of management on cropland can be beneficial for carbon and nutrient retention without risking (large) yield losses.

    Nevertheless, effects on soil carbon are small compared with extant stocks in natural and semi-natural ecosystem types and managed forests.

    While agricultural management can be targeted towards sustainable goals, from a climate change or carbon sink perspective avoiding deforestation or reforestation constitutes a far more effective overall strategy for maintaining and enhancing global carbon sinks.

  • Grassland responses to global environmental changes suppressed by elevated CO2

    Type: 
    Publication
    Publication date:
    Objective:

    The assumption that plants can absorb excessive fossil fuel emissions containing carbon dioxide because they need the gas in order to grow is challenged in this paper.These researchers report that increased levels of carbon dioxide (when combined with the other effects of climate change) actually suppress growth rather than helping plants to flourish. The three-year field experiment was unusual in looking at the effects of temperature, rainfall and nitrogen deposits, as well as carbon dioxide, in an attempt to mimic future climate conditions as accurately as possible.

  • Sistema Agroforestal Quesungual: Una Buena Practica de Adaptacion al Cambio Climatico

    Type: 
    Publication
    Publication date:
    Objective:

    In Central America, one of the major changes in land use is the conversion of natural vegetation to crops (mainly to grazing lands). The practice of slash and burn agriculture has led to a decline in soil quality through nutrients depletion, organic matter reduction and soil erosion. Land degradation problems and desertification have increased with climate variability. Climate change represents an additional threat that could affect a country"s ability to meet urgent demands for rural development--food security included.
