Invasive alien species (IAS) are a significant and growing problem worldwide. In Europe, some aspects of IAS have been addressed through existing legal instruments, but these are far from sufficient to tackle the problem comprehensively. The FINS II Conference considered the relevance of Top 20 IAS issues (Top 10 threats and opportunities) for Europe determined at the 1st Freshwater Invasiveness – Networking for Strategy (FINS I) conference held in Ireland in 2013. Using a similar format of sequential group voting, threats from FINS I (lack of funding, of awareness and education; poor communication) and several new threats (lack of lead agencies, of standardized management and of common approach; insufficient monitoring and management on private property) were identified by 80 academics, applied scientists, policy makers and stakeholders from 14 EU and three non-EU countries (including 10 invited speakers) during four workshop break-out sessions (legislation remit in both EU/non-EU countries; best management and biosecurity practice for control; data management and early warning; pathways of introductions and citizen science). Identified opportunities include improved cooperation and communication, education and leadership to enhance public awareness and stakeholder participation, systems establishment for early detection, rapid response, monitoring and management of IAS using standardised methods of data collection, storage and usage. The sets of threats and opportunities identified underline the importance of international cooperation on IAS issues in communication, education and funding as priorities, as well as in standardization of legislation, control methods and best practise of research

Cattle breeding is a very important part of agricultural production in Bosnia and Herzegovina (B&H), and milk production has a vital place in cattle breeding production. From an economic point of view, milk production is interesting as it is a daily production which presupposes faster marketing, which accelerates capital movement in agriculture, which in turn enhances liquidity. This research uses analyses of the existing state in milk production. The collected data are processed and cost calculation has been designed which enables the analysis of economic indicators of 4 dairy farm production models in B&H. Based on the collected data on features and values of dairy farm production models in B&H an analysis of expert evaluation was conducted as input data for DEXi method. The aim of this paper is to ascertain the basic indicators of business success of 4 dairy farm production models in B&H. Production-ecological, economic and socio-political features of the mentioned dairy farm models were analyzed. Based on the used criteria a rate of dairy farm production models using DEXi method was conducted. The results of the research in this paper using DEXi method show that the best model for dairy farm is model number four, which includes 45 milk cows.

The aim of this paper is to estimate marginal abatement costs (MAC) of N-fertiliser tax policies which aim to prevent NO 3 levels from rising. Estimates of MAC provide information on how large reductions in Nfertilisation rates should be before other measures are considered. Based on N-response experiments from Croatian field trials with maize, N-response curves were estimated and profit maximising N-doses were derived. Values of NO 3 -N concentration in lysimeter water from the same treatments were used to estimate an NO 3 -leaching function. A sample of 20 Croatian family farms was used to obtain records of producer and input prices as well as actual N-doses. Abatement costs and MAC for an N-tax, a product tax and an Nquota were estimated. The MAC for all the instruments are non-constant and increase at an accelerating rate. The MAC for N-taxes are positive for N-taxes lower than 60%, indicating a net return to society. Reduction rates in fertilisation up to this level should be achieved before considering governmental support for other measures. The N-tax has the lowest abatement cost and the lowest MAC for a particular level of reduction while the N-quota has a lower MAC than the product tax when total reduction levels are below 20 mg NO 3 l -1 .

The research aims to determine the conditions in the beekeeping sector of Mediterranean area at the case study of Dubrovnik-Neretva County, to identify areas with special environmental profile, to evaluate the honey produced in these areas and to analyze the possibility of linking beekeeping with tourism and related industries and services. According to a set of targets, several activities were conducted: analysis of the types of honey, technological processes and deviations from good beekeeping practices, determining the amount of investment, yields and income in honey production, analysis of the sales price, grade of marketability and sales channels of honey. The results show opportunities in production improvements by certain types of beekeepers, ways of beekeepers organizations and business associations and all that towards greater utilization of beekeeping capacity, as well as the increase of the commercial value of bee products and its integration with other economic activities. Keywords: business model, economics, Mediterranean beekeeping SažetakIstraživanjem se željelo utvrditi stanje u sektoru pčelarstva mediteranskog područja, na slučaju Dubrovačko-neretvanske županije, identificirati područja s posebnim okolišnim profilom, valorizirati med proizveden na tim područjima te analizirati mogućnost povezivanja pčelarstva s turizmom i sličnim djelatnostima i uslugama. U skladu s postavljenim ciljevima provedeno je više aktivnosti: analiza vrsta meda, tehnološki postupci i odstupanja od dobre pčelarske prakse, utvrđivanje visine ulaganja, prinosa i dohotka u proizvodnji meda, analiza prodajne cijene, stupnja 206Original scientific paper Journal of Central European Agriculture, 2018, 19(1), p.206-216 DOI: /10.5513/JCEA01/19.1.2038 tržnosti i kanala prodaje meda. Rezultati istraživanja dali su kvalitetnu podlogu za preporuku unaprjeđenja proizvodnje po pojedinim tipovima pčelara, načinima organizacije pčelarstva i poslovnog udruživanja proizvođača u pravcu većeg iskorištenja pčelarskih kapaciteta ovog područja, kao i veće komercijalne vrijednosti pčelinjih proizvoda, kako u okviru samog pčelarenja, tako i u njegovom povezivanju s drugim gospodarskim djelatnostima.
