Farmland prices and land-use changes in periurban protected natural areas

This paper provides empirical and conceptual insights in analysing the factors that determine the prices of farmland within Protected Natural Areas that are close to densely populated urban areas, the changes in land use experiences as well as the additional control policies needed to curb this unsustainable trend.The Urdaibai Biosphere Reserve nearby the metropolitan area of Bilbao (Basque Country, Spain) is the case study considered and its bordering non-protected rural area is used as a reference for comparison. A spatial hedonic farmland price model is estimated and the willingness of land purchasers to pay for different farmland characteristics quantified both inside and outside the Urdaibai Biosphere Reserve. The main results are that: (1) residential development is taking place in all categories of farmland, (2) aside from neighbouring prices, farmland prices depend on different factors depending on whether the marketed plots stand inside or outside the Protected Natural Area, (3) the “reserve effect” on land prices is less powerful than the “proximity to the metropolitan area (and motorway) effect” observed from villages of the non-protected area located in the 3rd crown of Bilbao, (4) the reasons for farmers non-compliance with policy regulations is the necessary knowledge base for the farmland conservation policy design and (5) in the light of the results, three development-control policy instruments such as Payments for Ecosystem Services, Tradable Planning Permits and development-taxes are discussed considering the factors that could improve compliance.

► Residential development is taking place in all categories of farmland.
► Aside from neighbouring prices, farmland prices depend on different factors depending on whether the marketed plots stand inside or outside the Protected Natural Area.
► The “reserve effect” on land prices is less powerful than the “proximity to the metropolitan area (and motorway) effect” observed from villages of the non-protected area located in the 3rd crown of Bilbao.
► The reasons for farmers non-compliance with policy regulations is the necessary knowledge base for the farmland conservation policy design.
► In the light of the results, three development-control policy instruments such as PES, TPP and development-taxes are discussed considering the factors that could improve compliance.
