Local farmer knowledge is key to sustainable agriculture when organic farming promotes biodiversity conservation. Yet, farmers may not recognize ecosystem service (ES) benefits within their agricultural landscape. Surveys were administered to 113 farmers, and the opinions of 58 respondents toward organic farming were analyzed to identify influential variables when deciding to farm organically. We classified responses by geographic category within a socio-economic production landscape (SEPL), and by social influence categories. With principal component analysis (PCA), a two-scale, four-phased analysis was conducted. Coastal farmers (n = 22) were the most positive towards organic farming trends due to consumer demand. Plains farmers (n = 18) were highly interested in future opportunities for achieving consumer health and food safety objectives. Mountain farmers (n = 18) perceived the most organic transitioning barriers overall, namely irrigation. In all three geographic categories, farming decisions were not primarily related to biodiversity conservation or ES management, but rather to farming community patterns, consumer feedback, and a lack of barriers. Further, farmer opinions toward organic practices were more influenced by their life experiences than by school-taught concepts. Since no previous studies have assessed the knowledge, values, and opinions on organic farming of Taiwan's west coast farmers from an ES perspective, the proposed approach both identifies farmers' knowledge and opinions, and verifies a satoyama landscape with PCA results for informed decision making.Sustainability 2019, 11, 3843 2 of 27 childhood [9] and are relatively stable throughout an individual's life stages [10] (the basis for school taught environmental education), it may also be necessary to first demonstrate to local stakeholders the benefits of ESs within their agricultural landscape [11].Organic farming practices utilize ecosystem approaches to integrate agricultural biodiversity conservation and sustainable land use, and also include a concept of fairness related to the reciprocal relationships between the environment and 'life opportunities' [12]. While conventional agricultural systems disrupt the heterogeneity of natural habitats resulting in less biodiversity [3,13], organic farming minimizes this disruption with natural approaches to maintain biodiversity and reverse local species decline due to conventional agriculture practices [3,13,14]. Generally reported in ES research, agricultural ESs (i.e., provisioning ES) result in negative tradeoffs with other ESs (e.g., decreases in runoff water quality as a result of increased crop densities, which necessitates increased pesticide applications [2]), whereas synergies are often reported between regulating and cultural ESs such as increased aesthetic appeal as a result of increased pollination from flower planting [15]. However, synergies can also be found between agricultural ESs and other ESs when organic practices promote biodiversity [16].The ES relationships within a lan...
