Modelling the effects of agricultural policies on high nature value farmland: a farming systems approach
Publication . Ribeiro, Paulo Pacheco de Castro Flores; Santos, José Manuel de Lima; Moreira, Francisco
In recent years, High Nature Value (HNV) farmland became a priority for biodiversity conservation in Europe. Covering about 1/3 of total agricultural area in Europe, HNV farmland is in decline mainly because of agriculture abandonment/intensification driven by markets and public policies. HNV farmland is mostly provided by low-intensity and traditional farming systems, largely on less productive areas. Given the multiple environmental public goods provided by HNV farming systems, agri-environment schemes were set under the Common Agricultural Policy (CAP) to maintain HNV farmland, although with mixed results. Recent policy changes, including the decoupling of direct payments during the 2003 CAP reform, led to changes in farming systems which often further undermined HNV farmland sustainability. This research aims at evaluating the resilience of HNV farmland under policy change based on a farming systems approach, seeking to contribute to improving the design of agri-environment policies.
Focusing on HNV farmland in southern Portugal, we used farm level data from the Integrated Administration and Control System and the Land Parcel Identification System provided by the national CAP paying agency for the years 2000 to 2010, complemented with farm survey data, to derive a farming systems typology which was used to 1) assess agricultural changes over this time period, related with changes in the policy framework (e.g. 2003 CAP reform); 2) assess the extent to which this approach enables the identification of HNV farming systems, based on landscape features and farming practices, and; 3) model the choice of farming system based on farms’ biophysical and structural features and on economic and policy variables, to assess scenarios of market and policy change and derive a supply curve for biodiversity conservation services.
The farming systems approach proved to be a relatively simple way to identify HNV farming systems and a promising tool to improve the cost-effectiveness EU agri-environment policy, suggesting the feasibility and benefits of a CAP direct payment scheme aimed at HNV farming systems.
