  • Impact of climate dynamics on cyclical properties of wine production in
           Douro region using time-frequency approach

    • Authors: Mario CUNHA, Christian RICHTER
      Pages: 56 - 82
      Abstract: Abctract. In this paper we model the impact of climate dynamics on wine production temporal cycles for the period 1933 to 2013 in the Douro wine region. We identify the cyclical properties of wine production and which cycles are determined by spring temperature and soil water levels during summer. We achieve that by applying a time-frequency approach, which is based on Kalman filter regressions in the time domain. The time-varying autoregressive model can explain 79% of the variability of wine production in Douro region. We then transfer the results in the frequency domain and can show that wine production is characterized by two cycles of 5.7 and 2.5 years around the long run trend. The in-season spring temperature as well as the temperatures of two and three years ago could explain about 65% of the variability of wine production. When the soil water level in summer is incorporated, the R2 increases to 83% and the Akaike criterion value is lower. The effects of soil water in wine production are depending on the timing. The in-season effect of an increase in soil water is negative, whilst soil water from two and three years ago have a positive effect on wine production. There is a stable but not constant link between production and the spring temperature. The temperature is responsible for two long-medium cycles of 5.8 year and 4.2 years as well as a short one of 2.4 years that began since the 80s. The soil water level can explained 60%of the 7 years cycles of wine production as well as a short one of 2.3 years cycle which has been happening since the 90s. We can recognise a shift of the relative importance away from temperature to soil water. Despite using a new an extended dataset, our results largely confirm the results of the impact of climate on the wine production in Douro region in our previous research. Modelling the impact of climate on the wine production can be an important instrument contributing for mitigation strategies facing the projected climate conditions in order to remain competitive in the market.Keywords.

  • Challenges of industrial policy to enhance competitiveness

    • Authors: Charis VLADOS, Dimos CHATZINIKOLAOU
      Pages: 83 - 96
      Abstract: Abctract. This study explores how the traditional approaches of perceiving competitiveness and industrial policy could be enriched through a synthetic and evolutionary perspective. Competitiveness, in particular, tends to be studied in the literature in a relatively fragmented way, focusing either on the level of individual nations, or on the sectors of economic activity, or on the firm level. As a result, the evolutionary structures that define competitiveness in a unified socioeconomic way are usually bypassed. In this context, the traditional approach to industrial policy-making, which has as sole objective the strengthening of specific sectors, is inadequate to enhance the multilevel socioeconomic competitiveness in our days. Therefore, we suggest a comprehensive re-positioning of the concept of "organic competitiveness" in overall and synthetic socioeconomic terms (firms-sectors-socioeconomic systems) as useful for a redirected modern industrial policy.Keywords.

  • Study on sustainability of Bulgarian agro-ecosystems

    • Authors: Hrabrin Ianouchev BACHEV
      Pages: 118 - 154
      Abstract: Abctract. Despite huge progress in the theory and practice of this new area, still there is no consensus on how to assess the sustainability of agro-ecosystems due to diverse understandings, approaches, methods, employed data, etc. In Bulgaria there are practically no deep studies on sustainability level of diverse agro-eco-systems. This paper tries to fill the blank and assesses the sustainability level of agro-ecosystems of different type in Bulgaria. First a holistic hierarchical framework for assessing integral, economic, social and ecological sustainability of agro-ecosystems in Bulgaria is suggested including 17 principles, 35 criteria, and 46 indicators and reference values. After that, an assessment is made on overall and aspects sustainability of large (agro)ecosystems in North-Central, South-Eastern, South-Central and South-Western geographic regions, and particular main and specific types of agro-ecosystems of the country - mountainous, plain-mountainous, plain, riparian (Struma, Maritza, Yantra), southern Black Sea, mountainous area with natural constraints, non-mountainous area with natural constraints, protected areas and reserves, Western Thracian Plain, Middle Danube Plain, Dupnitsa and Sandansko-Petrich Valley, Sredna Gora Mountains and Western Rila Mountains. The assessment is based on first-hand information collected though in-depth interviews with the managers of “typical” farms in the respective ago-ecosystems. The study has found out that there is a considerable differentiation in the level of integral sustainability in agricultural ecosystems of different types. Furthermore, there are substantial variations in the levels of economic, social and ecological sustainability of agro-ecosystems of different type, and the critical indicators enhancing or deterring overall and particular sustainability of individual agro-ecosystems.Keywords.
