FSSIM-AM: Agricultural Management
Aim of FSSIM-AM
Aim of the Agricultural Management Module is to describe, generate and quantify
production techniques of current and alternative production enterprises which can
be evaluated by APES (Chapter 4, this Volume), or other cropping/livestock system
models, in terms of production and environmental effects. In this chapter, we focus
on annual crop activities to describe FSSIM-AM, although the same methodologies
have been used for livestock and perennial activities. The fully quantified activities
i.e. the complete sets of agricultural inputs and outputs are assessed in FSSIM-MP on
their contribution to the farmer's and policy goals considered. Alternative activities
are new activities or currently not widely practised activities in the study area, and
include technological innovations or newly developed cropping or husbandry practices
(Van Ittersum and Rabbinge
1997
; Hengsdijk and Van Ittersum
2002)
. Current
activities are widely practiced in a sample region and their management operations and
some of the associated outputs can be based on observed data and expert knowledge.
