Economic impact of the bioeconomy in Spain: Multiplier effects with a bio social accounting matrix
تأثیر اقتصادی اقتصاد زیستی در اسپانیا: اثرات چند برابری با ماتریس حسابداری زیست اجتماعی-2021 The bioeconomy emerges as a new economic model to help address issues related to environmental care
and focus on a more sustainable economy. In the last decade, it has become a global priority and many
countries have published their own strategies that clearly refer to the development of the bioeconomy.
The symmetric social accounting matrix with basic prices was constructed, including the breakdown of
biobased accounts belonging to the bioeconomy to determine which sectors of the bioeconomy are most
strategic to promote sustainable economic growth. This constructed matrix was used to analyse the
economic influence of the bioeconomy products and their impact on job creation. The analysis was
carried out using the diffusion and absorption multipliers, which enabled the interpretation of the
linkages between the different economic agents. The results were analysed in depth and the multipliers
decomposed into their different effects, own, open and circular, and complemented with the calculation
of the employment multiplier to evaluate the most important sectors for employment generation. The
analysis was applied to the case of Spain. The results of this research enabled the identification of the
strategic sectors where economic policies can be applied since these are the ones that increase economic
growth and activities within the bioeconomy and create jobs. The conclusions indicated that the Spanish
bioeconomy is still focused on traditional sectors and has not yet developed its potential in more
innovative biobased products, demonstrating that the bioeconomy in Spain still has a long way to go.

An integrated model for marine fishery management in the Pearl River Estuary_ Linking socio-economic systems and ecosystems
یک مدل یکپارچه برای مدیریت ماهیگیری دریایی در رودخانه مروارید خور: ارتباط سیستم های اجتماعی و اقتصادی و اکوسیستم ها-2016 The paper devises an integrated ecological–economics–social model to assess the implementation of ecosystem-based fisheries management in the Pearl River Estuary (PRE) in the South China Sea (SCS). In particular, this paper presents the development of an integrated model, which links a regional economics social accounting matrix (SAM) model to an ecological model constructed using Ecopath with Ecosim (EwE) software. The impacts on the ecological–economics–social system are examined by varying fishing efforts for four scenarios, including status quo management, fishing effort reduction policy, fishing gear switch policy, and summer closure extension policy. Key results from the predictions (2010–2020) and policy simulations illustrate that the collapse effect is apparent in the status quo scenario. Further, re- ducing or switching of fishing effort (e.g. elimination of overfishing and reduced habitat disturbance) positively affects the ecosystem and can lead to economic and social welfare gains in the PRE's economy. The gear switch scenario presents a compromise among the economics, social, and conservation metrics, and also outperforms other scenarios in terms of biomass at the end of the simulation period. The fishing effort reduction policy performs better than the summer closure extension policy in terms of the con- servation metrics but does relatively poorly in economic terms.& 2015 Elsevier Ltd.
