The scale and pattern influences on the hedgerow network's effect on landscape processes: first consideration about the need to plan for landscape amelioration purposes.Environmental Management and Health (2002)
AbstractIn the last decade we realised several rural landscape amelioration plans (Italy) by means of diffuse reintroduction of agroforestry linear plantations. To this end a GIS decision support system was developed, that has been progressively implemented by design problem solutions and field/simulation research. Given that hedgerow (re)introduction could be a mean for the improvement of rural landscape processes, up to day we have reached the conclusion that planning is a necessary way to optimise such a transformation for socio-economic and intrinsic reasons. In the first case since (i) the best field application at the landscape scale of technical and scientific knowledge by single farmers is not widespread (the single presence of an efficient training institution is not sufficient); (ii) the probability that the single farmer’ s reaction to specific economic incentive regimes would be spatially or timely uniform and coherently addressed to an optimum landscape resource allocation is very low. In the second case a landscape-scale structure as an hedgerow network should show intrinsic characteristics, and these characteristics should be optimised at this scale. Actually we have obtained indications from field and simulation research developed in these years (reported in this paper) that at the landscape scale the behaviour of an hedgerow network is specific of this structure, and not equal to the sum of the single hedgerow effects on different landscape processes (wind and hydrologic processes, economic processes, perceptive processes). Therefore: a) we need to be able to distinguish the effect of the agroforestry systems (mainly hedgerow) among different scales (single planting/landscape) and different patterns (isolated systems/networks) in order to optimise their positive effects on landscape processes at different scales; b) it is not possible to optimise landscape transformations by means of agroforestry network implementation without a planning action able to evaluate them.
