An emerging shift: ecosystem service production in the rural landscape
Is it a concept offering broad application Is it a concept offering broad application (not tool(not tool--dependant)?dependant)?
A A stewardship stewardship or MOP framework in Victoriaor MOP framework in Victoria
An emerging shift: ecosystem service production in the rural landscape
Global shift
Ecosystem Services include:
Water quality and quantity
Food and fibre –crops, timber
Biodiversity, habitat - including
pollination and natural pest
control
Waste breakdownAtmosphereand Climate -
including carbon sinks
An emerging shift: ecosystem service production in the rural landscape
Global shift
The Millennium Ecosystem Assessment concluded that 24 ‘ecosystem services’reviewed, including a stable climate, fresh water, fresh air, soil fertility, pollination of crops, waste adsorption and nutrient recycling some 15 are being degraded or used unsustainably.
The regulating and provisioning ‘ecosystem services’ of healthy landscapes - once considered free - are increasingly being understood as valuable, finite and that we face enormous risks as we degrade them.

Language:
Challenge: the heterogeneity of the problem -landscapes needing to fulfil multiple functions.
(regulatory, production, nature, cultural…)
Leads without exception to land use conflicts.
Decision support systems needed that can consider a number of different functions simultaneously

Landscape Integration, optimisation Modelling Future LandscapesThe methodology to integrate partly contradicting goals and targets into rural and landscape development is not well developed. There are different approaches for the development of integrative goals (leitbilder) depending on the specific sciences from which they originate, e.g.
agricultural or land economy,
biodiversity planning
hydrology
geography.
The aim of the session is to discuss different approaches to the integration of multiple goals or targets into consistent models (e.g. spatial decision support systems, linear-programming based models, multicriteria analysis, scenario techniques, landscape prognosis) and related problems and needs.
