3) encourage a full range of organic life,<br />

4) develop balanced self-sustaining communities<br />

5) control of systems through management by<br />

tending habitats, species and stages of growth to<br />

achieve the lowest level of daily maintenance creating<br />

a maximum variety of opportunities for people<br />

and nature to coexist by influencing activity and separating<br />

conflicting interests and creating a coherent<br />

landscape structure that assimilates variety with out<br />

disorder, and provides a continuous sequence of<br />

aesthetic experiences throw the interplay of landform,<br />

space and enclosure, light and shade, and all<br />

others sensory qualities of the landscape ; (list modified<br />

by Solar 2009) from Manning 1979, p.30).<br />

2) Wildlife needs: using birds as indicators of habitat<br />

health and biodiversity and taking care about built<br />

environnemental influences over natural habitats.<br />

3) Human recreation needs: social interaction, emotional<br />

freedom, pride, aesthetic appreciations,<br />

wellbeing, joy, wonder and excitement, intellectual<br />

education, awareness, recreation fitness, exercising<br />

the senses (modified from Mostyn by Briffet 2001<br />

and Solar 2009).<br />

How can we organise multiple information sources and<br />

a database of diversity of open spaces in a dependant<br />

relation of functions between humans and wildlife? How<br />

can we manage such a complex landscape project that<br />

involves environmental, socio-cultural and economic<br />

affaires? A political program of nature and landscape<br />

governance must be installed.<br />

Results: a method to compare the governance, connectivity<br />

and multifunctionality of periurbans ecological<br />

networks political programs.<br />

What is a regional ecological network political program?<br />

It is a consensus between the regional stake holders<br />

(Top-Down and Bottom-Up) to design and to manage<br />

an ecological (for the biodiversity) landscape (for the<br />

users) program using certain criteria and tools. Can we<br />

provide a versatile method to compare convergences,<br />

divergences and good practices of periurban ecological<br />

network political programs?<br />

A) Regional context / Top-Down : Lille Green Metropolis<br />

( fig 1) and Nature & <strong>Landscape</strong> program of Geneva<br />

canton ( fig 2):<br />

1) landscape identity: the initial conditions as a result of<br />

landscape evolution that have allowed the landscape<br />

conservation and connectivity of main regional<br />

patches, corridors and periurban farms, during the<br />

XX century (laws concerned, regional landscape<br />

protection in regional plans, industrial non functional<br />

sites, regional water reservoirs, historical forests,<br />

etc);<br />

2) political programs in development; a) goals, statements<br />

and fostering media campaigns of the political<br />

policies of forester spaces, riparian system, biodiversity,<br />

rural landscapes, culture and recreation; b)<br />

concept spatial of regional landscape connectivity<br />

strategy between main patches and corridors; c)<br />

territorial administration by perimeters.<br />

B) Local context / Bottom <strong>–</strong> up : La Deûle Park in Lille<br />

and Equestrian agro-environmental network of Colver in<br />

Geneva;<br />

1) spatial concepts of landscape connectivity, a) patches,<br />

corridors, zones tampon and barriers b) landscape<br />

compatibility conditions (control of accessibility<br />

and landscape continuity between patches and<br />

corridors for people), 3) connectivity with the urban
