Preliminary census and an official data analysis at the level of the province to sum-marise the existing information on pig production and future policies.
Operational typology depending on various criteria explaining the current production and availability of animal-produced organic matter
Appraisal of rejected effluents produced by each category of pig farmers
Implementation of a Pro-Active Conciliation Tool (PACT) method applied on collective identification of individual constraints, identification of other stakeholders and their existing or possible relationships, opinions and personnal perceptions about the local animal-waste pollution issue. It will involve a ‘local expert’ committee gathering concerned stakeholders and policy makers.
Creation of a Meta-database on NPK balance in Crops at commune level
Identification of fish ponds farming and their practices in manure-based feeding management
Economical appraisal of commercial relationships between manure producers, retailers and consummers , i.e. vegetable farmers.
In a circumstance where the existing land use maps are outdated this is the only source of information allowing understanding the dynamic of the urban and agricultural areas. An indicator of pressure on the environment will be set up. It will describe also the decreasing of organic matter spreading areas:
The GIS will be designed to receive the different kind of information from other components. It will gather:
to optimise the animal organic matter production and consumption considering various constraints: adequacy between pig effluents and crops/fish ponds requirements, periods, distance, costs. With data from observed farming typologies and decision rules, this spatial model will identify possible transfers with a mapping considering OM production/demand balance, and then the amounts of animal waste needed to be spread as well as storage needs and associated technologies. A hierarchy will be established between all the parameters with weightages and a map of the environmental risk will be produced.
