Companies are facing a rapidly changing and ever more challenging environment. Globalization, together with a shifting political landscape, is combining with major transformations in population, urbanization, resource utilization, climate change and consumer attitudes. Through the evolution of communications networks there is growing connectivity that with the rise of non-governmental organizations (NGOs) results in an increasingly transparent society. Socially responsible investors combining forces with the media and NGOs have emerged as a major force compelling firms through the capital markets toward a more environment friendly behaviour. The global food industry is especially susceptible to climate change and shifting consumer attitudes and thus has to increasingly respond to external stakeholders in order to remain competitive. How did attitudes and perceptions change in recent years toward the industries environmental performance and how did this influence their financial results? Our research investigates forty-six global food industry companies.

For understanding local and regional seed dispersal and plant establishment processes and for considering the ecotypes and other forms of specific variability, hard data of locally or regionally measured traits are necessary. We provided newly measured seed weight data of 193 taxa, out of which 24 taxa had not been represented in the SID, LEDA or BiolFlor databases. Our new measurements and formerly published data of locally collected seed weight records together covers over 70% of the Pannonian flora. However, there is still a considerable lack in seed weight data of taxonomically problematic genera, even though they are represented in the Pannonian flora with a relatively high number of species and/or subspecies (e.g. Sorbus, Rosa, Rubus, Crataegus and Hieracium). Our regional database contains very sporadic data on aquatic plants (including also numerous invasive species reported from Hungary and neighbouring countries) and some rare weeds distributed in the southwestern part of the country. These facts indicate the necessity of further seed collection and measurements.

The first version of the map of the Hungarian vegetation-based landscape regions were prepared at the scale of 1: 200,000 (1 km or higher resolution). The primary goal of the map was to provide an exact background for the presentation and evaluation of the data of the MÉTA database. Secondly, we intended to give an up-to-date and detailed vegetation-based division of Hungary with a comprehensive nomenclature of the regions. Regions were primarily defined on the basis of their present zonal vegetation, or their dominant extrazonal or edaphic vegetation. Where this was not possible, abiotic factors that influence the potential vegetation, the flora were taken into consideration, thus, political and economical factors were ignored. All region borders were defined by local expert botanists, mainly based on their field knowledge. The map differs in many features from the currently used, country-wide, flora-or geography-based divisions in many features. We consider our map to be temporary (i.e. a work map), and we plan to refine and improve it after 5 years of testing.
