AG 21 - Agriculture in the 21st century – costs and benefits for societies and environments

Initiators: Holm Tiessen (Germany), Dennis Ojima (USA)


SCOPE is developing a new RAP project starting in 2005 to perform an integrated review of the challenges and opportunities provided by agricultural practices and new technologies in the 21st century. It will liaison with related activities of the Global Change research programmes (in particular IGBP/Land and ESSP/GECAFS) and the CGIAR network. The objective is to assist in identifying a set of comprehensive questions for new research and assessment in this field, and provide guidance towards further studies on specific topics in the coming years.

This Rapid Assessment Process project will address:

The traditional, continuing challenges which result in a process of marginalisation of poorer land users and include:

  • degrading resource base and declining fertility
  • expansions into marginal lands
  • outmigration and labour shortages

and on the other end of the wealth spectrum:

  • the environmental impacts of intensification and concentration of production.

with an underlying constraint to all agricultural production provided by:

  • increasing cost of inputs and declining commodity prices,
  • decreasing availability of water
  • an increasing awareness of product safety generates monitoring systems and institutions that affect production and trade patterns

A new direction for agricultural technology and practice results from the increasing importance of the carbon economy:

  • the importance of C sequestration in Global Climate Change mitigation
  • the demand for renewable energy production from agriculture and forestry

The new transgenic organisms will play an increasing part in production and debate; among the opportunities provided by GMO’s are:

  • improved production efficiency,
  • increased value of products,
  • reduced agrochemical use,
  • reduced tillage and improved C sequestration,
  • intensified production, creating opportunities for protecting other areas;

at the same time challenges will be provided by:

  • contamination of natural gene pools, "genetic pollution",
  • closure of markets,
  • effects on consumer health,
  • effects on non-target organisms,
  • other technology-specific threats such as the escape of antibiotic resistance or inducer genes

The role of knowledge systems and their application may provide new opportunities:

  • increasing understanding of ecosystem function applied to agriculture may improve efficiencies and reduce the potential for degradation;
  • modelling of crops and ecosystems will provide mechanisms for the synthesis and transfer of knowledge
  • Geographic Information Systems will provide opportunities to adapt practices to landscapes, resulting in precision agriculture and improved decision-making tools for landuse planning

Social adaptation that follows from changes in the

  • resource endowment,
  • trade patterns
  • production patterns
  • increasing regulation

Results of the analysis will be published as a synthesis volume, and other products will be directed towards policy planners and management.
