Abstract:

Current issue of bioeconomy development has been largely addressed on a linear or interdisciplinary level, however holistic view of bioeconomy requires a transdisciplinary system analysis. Developed methodology clarifies vision on bioeconomy definition, bioeconomy disciplines and disciplinary definition in context of nexus interlinkage, in the result concept of transdisciplinary approach connection to bioeconomy is determined as processes for sustainable bioeconomy, that not only replace fossil resources with biobased resources, but strengthens different disciplines, taken into account interlinkages, knowledge, and stakeholders and limitations set by planetary boundaries, different dimensions should be included in transition towards sustainable bioeconomy. Methodology bases on critical literature analysis. Different bioeconomy disciplines are defined and the obtained results are represented graphically. The obtained results can be used for further research as a transdisciplinarity basis of the bioeconomy, studying specific systems, factors influencing them and evaluating potential scenarios and their impacting tools. Results from implementing holistic vision would provide practical benefit to policy makers and industry actors by providing an analysis how to improve industrial practice, policy and how more effectively transfer to sustainable bioeconomy.

Abstract:

To identify production systems that could increase local milk production in a sustainable manner, a study was conducted on 135 dairy farms in the three main plains of the Chelif Valley, Algeria. These have been evaluated for environmental, social and economic sustainability based on the IDEA (Farm Sustainability Indicators) method.
The Principal Component Analysis identified 4 different types dairy production systems, namely Type 1: Medium-size dairy farms with cereal crop production; Type 2: Small-size dairy farms; Type 3: Medium-size dairy farms diversified crop production, and Type 4: Large-size dairy farms with diversified crop production.
Comparative analysis of ecological sustainability showed better results for medium-size dairy farms with cereal crop production (52.3 ± 10.17 / 100 points) and for large-size dairy farms with diversified crop production (51.6 ± 10.38 / 100 points), while the economic sustainability was better for medium-size dairy farms with diversified crop production (51.6 ± 19.20 / 100 points). On the other hand, social security was the weak point for all farm types.
On the regional level, it appeared that agri-environmental scores were better in Middle and Low Chelif valley while the best economic performances were recorded in High Chelif valley. On the regional level, it appears that the scores of agri-environmental scales are better in the middle and low Chelif while the economic performances are comparable between the three localities.
