Abstract
Simple SummaryThe livestock sector is the main source of income for the inhabitants of many rural areas, but the environmental problems generated by this industry have led to the emergence of new regulations to make the sector more environmentally friendly. The aim was to identify suitable areas where the livestock sector could be developed, complying with all sectoral standards, and classify the outranking suitable municipalities according to socio-economic, sectoral, and environmental factors. Socio-economic, to make it a key sector for the development of rural areas with depopulation problems; sectoral, to avoid generating health risk; and environmental, to avoid risks of water pollution and degradation of natural and forest areas. The results showed that there was a clear correspondence between the most suitable areas for pig farming and areas with depopulation problems or where rural tourism had not been developed. This information allows the design of public management instruments to prioritise the development of the sector in these areas.The concentration of livestock production is problematic due to environmental concerns. European regulations are guiding the sector to become increasingly sustainable and, at the same time, maintaining the population in rural areas. The aim was to determine suitable areas in municipalities where livestock is presented as a market option. The methodology applied was based on the combination of multi-criteria methods and geographic information system (GIS) techniques, following three steps: removal of unsuitable zones by sectoral regulations (STEP 1); removal of unsuitable zones due to urban planning, and environmental recommendations (STEP 2); and evaluating the resulting areas depending on the importance of socio-economic, sectoral, and environmental characteristics. This study was based in a Spanish region with ongoing conflicts over land use on the coast but with a high number of rural municipalities at risk of depopulation in the interior. The results showed that 33% of the municipalities of the Valencian Community (VC) had suitable and outranking areas for the development of the swine sector. The 43 municipalities with the highest scores were because of the socio-economic factor and confirmed that suitable livestock development in municipalities with the highest risk of depopulation and low rural tourism activity was a key issue for development.
Highlights
To assess suitable livestock areas, this paper proposed a areas than compensatory multi-criteria approaches, as some factors cannot comhybrid procedure based on two multiple-criteria andsteps, analytic hierarchy process (AHP).for
The urban planning regulation and environmental recommendations for the siting of farms were considered in STEP 2
The resulting map of municipalities with land suitable for the development of the swine sector was classified into four levels according to the score value
Summary
39% of the final livestock production, with significant growth in production, census, and the number of farms [1] due to the thrust of foreign markets and the competitiveness of the sector in the world market. Increasing exports to third countries, especially China and other Southeast Asian countries. It is the first EU country in the number of animals, with about 21%. Intensive livestock production entails several environmental risks related to the concentrated production of manure [3,4,5,6,7]. Land planning contributes to more rational distribution of animal production and manure disposal [13], and it is, essential to reduce the environmental risks related to intensive livestock production [5]
