The development of strategies for improved agricultural systems and land-use managementey might be stimulated is the central task of agricultural systems research. But past experience in systems research in non-agricultural fields, where systems research methods developed, shows that a scientific approach to management has had limited effect on what managers actually do. In agricultur

Needs and priorities of NARS for the management of natural resources: Bangladeshopment. The density of population is already one of the highest in the world (less than 0.1 ha per person) and the population is growing fast. During the last two decades agricultural production has increased at an annual rate of 1.8 percent. The area under non-cereal crops has declined and the prod

Bhutan’s research needs and priorities for the management of natural resources: a small country’s pevided strong policy leadership and support for the integration of a natural resource management (NRM) perspective into the agricultural research agenda. Research has been reorganized to reflect more closely the interdependencies between crops, livestock, and trees found in traditional land-use syste

The institutional and organizational implications of integrating natural resource management and prol resource management and environmental concerns into their agricultural research agendas. Integrating these concerns adds significantly to the responsibilities of NARS at a time when there is already a heavy demand on their shrinking research resources. NARS face the difficult task of maintaining a

Data requirements for agricultural systems research and applicationsch is needed as inputs or as constraints for simulation models and as validation of simulations to establish the credibility of the systems approach. If agricultural and land-management simulation models are to be useful for solving problems, they need to include in the detail of the simulation repr
