Earth's ecosystems provide for humanity full range of benefits known as ecosystem goods and services. By the processing of information was used the methodology of Millennium Ecosystem Assessment (4 groups of ecosystem services). The paper assessed the first group of services - provisioning services with the possibility of using agricultural lands for growing energy plants. In the paper are evaluated the energy plant Miscanthus and Populus. The crop Miscanthus (covered 2010-2014) presented two genotypes. In 2012 (the third year of growing) has been reached the production of 24.85 t ha-1 (60% more than in 2011). In 2014 (the fifth year of growing) the crop reached production 28.60 t ha-1 of dry biomass. The plantations Miscantus x giganteus genotype planted the rhizomes are appeared productive. Fast-growing poplars Italian provenance, in the first three-year cycle in 2012 formed 51.47 t ha-1 of biomass. In 2014, the second year of the three-year harvest cycle average value of their biomass was 34.40 t ha-1. Based on an assessment of production above-ground organs monitored varieties of poplar are more productive varieties Monviso and Pegaso. Based on the evaluation of the ability of energy plant plantations (grasses genus Miscanthus and woody plant of the genus Populus) to produce enough above-ground biomass for energy use can be confirmed the high prevision service of this type of cultural ecosystem (agro-ecosystem).

We analyse the Swiss import structure of the agricultural and food sector from developing countries (DCs) and least-developed countries (LDCs) which benefit from the Generalised System of Preferences (GSP). Between 2002 and 2011, 46% and 36% of the agricultural products from the DCs and LDCs, respectively, were imported under the GSP scheme. However, most of the agricultural products from DCs and LDCs entered Switzerland under a most favoured nations (MFN) of zero. The estimations of a gravity model underpin the findings of the descriptive analysis: Being simultaneously a member of the WTO and in the GSP scheme fosters agro-food imports from DCs and LDCs significantly. Furthermore, the productivity and supply capacity within the agricultural sector depicted by the agriculture gross domestic product of a trading partner has a strong and significant positive effect on imports.

This study examined productivity differentials along gender lines of cocoa farmers in Abia state, Nigeria in 2015. Multi-stage random sampling technique was used to elicit data from 120 cocoa farmers, whom consist of 60 males and 60 females. Data were collected using a well structured questionnaire and interview schedule administered on the respondent. Data were analyzed using profitability analysis and semi-log regression function. For the male farmers, the coefficients for education, farm size, fertilizer, input and planting materials were positively related to productivity and significant at 5% level of probability while capital inputs was significant at 1%. For the female farmers, the coefficient for age was negatively related to productivity and significant at 1%, while education, farm size, capital input and fertilizer inputs were positive; both were significant at 1.0% and labour was significant at 5% level of probability. From the profitability analysis, the female cocoa farmers were more profitable with the profit of N1412432 than their male counterparts with the profit of N1373643. The results call for policies aimed at land re-forms by making more lands and easy accessibility to credit available to women who are more efficient for increased productivity and profitability.

Support and promotion of export are key elements of sustainable development, export representing at the moment growth domestic main engine. The objectives of the paper were to analyze the activities of foreign trade and economic cooperation, and the support for the domestic economic development and harmonious integration of Romania into the complex system of international relations. The methods used in this paper were: comparative analysis, bibliographic study and processing of the statistical data from the National Statistics Institute in order to generate some proposals for developing a future strategy for promoting Romanian food products on foreign markets. The main results refer to the situation of agriculture in recent years, the situation of export and import of agricultural products. The main conclusion is that the rising of prices represents an opportunity for countries with strong agricultural sectors.

The paper aimed to analyze the concentration of pig livestock and pork production in Romanai between 2007-2014 based on the empirical data provided by National Institute of Statistics. Pork production declined due to the continuous pig livestock decrease. Pig distribution is relatively uniform by micro region of development. The West region is in the top for the pig livestock and pork production. It is followed by South Muntenia and South East regions. In all the other regions, pork production declined. The lowest pork production is in Bucharest-Ilfov area. The values of Herfindahl-Hirschman Index varied between HHI=0.137 in 2007 and HHI= 0.154 in 2014, while the Gini-Struck coefficients ranged between GS=0.119 in 2007 and GS=0.159 in 2014, reflecting a good uniformity of production distribution but also a slight trend to a moderate uniformity to the end of the period. As long as domestic production is not enough to cover consumption, pig breeders should be supported to increase production, otherwise they will fail and imports will continue to cover market demand because of the overproduction in the Western countries.

The paper aimed to analyze the concentration of tourist arrivals in Romania based on National Institute of Statistics Data for the period 2008-2013. In Romania the tourists arrivals increased reflecting a higher demand for touristic attractions of the country. In 2013, the number of tourist arrivals accounted for 7,943,153, being by 11.47 % higher than in 2008, when it was 7,125,307 arrivals. The highest number of tourist arrivals is in the Centre, Bucuresti-Ilfov and South East regions, totalizing 56.19 % of the total number of tourist arrivals, and the lowest number of tourists was recorded in South West Oltenia. The regions where the number of tourists increased were Centre, Bucuresti-Ilfov, South West, North East and West, and the regions where the number of tourist arrivals declined were the South East, South Muntenia and North West. The Herfindhal-Hirschman Index has small values, closer to zero, reflecting a relative uniformity among regions. It varied between 0.1387 in 2008 and 1.490 in 2013. The Gini-Struck Coefficient ranged between 0.1252 in the year 2008 and 0.1658 in the year 2013, reflecting again a relative uniform distribution of tourists arrivals by development region, in all the years, except 2012, when its value accounted for 0.51, reflecting a moderate concentration among regions. The low degree of concentration is justified by the large variety of attractions Romania could offer in all the regions. It is about cultural heritage, historical place, landscapes, gastronomy, accommodation units at various prices.

The paper aimed to analyze the economic efficiency in Romania's tourism in the period 2005-2014 using the Eurostat data base. In the analyzed period, Romania was visited by more tourists (+33%), more foreign tourists (+25 %), meaning by 46.93 % more tourists per inhabitant. Also, tourism receipts increased by 62%, and expenditures increased 2.44 times. But, tourism contribution to GDP which is just 0.9 %, very low compared to other EU countries, and Romania's contribution to EU-28 receipts is very small, just 0.24% and in a decreasing trend. The share of tourism receipts in export value is just 2.64 % and in a declining trend. Tourism receipts per international visitor increased by 33.88% not only because the increased number of foreign tourists, but also due to the high tariff per tourism services and high VAT practiced in Romania. Romania registered a deficit of - 446 Euro million in Tourism Payment Balance, and the TTC Index value was just 3.78 in 2015, placing Romania on the 66th rank. Despite its huge potential for tourism, Romania is not yet able to develop an efficient tourism. A permanent promotion and extend of services size and quality on various markets are required to increase economic efficiency and competitiveness of Romania's tourism.
