Groundwater is a vital resource, when considering its role in the water supply for human activities. Regardless their location, the quality of groundwater resources is influenced by different natural and anthropic factors, especially if the hydro geomorphological settings allow the pollutants to reach the aquifer from the ground surface. Various methods for aquifer vulnerability assessment were developed over time. This paper presents the vulnerability assessment of the karst aquifer Zaton-Bulba, situated in the South-Western part of Romania, in the Mehedinti Plateau. Two specific methods were used for the vulnerability assessment of this aquifer. The first method is DRASTIC which is a general method that can be applied for any kind of aquifer and the second method is EPIK which is a method developed specifically for karst aquifers. These methods were chosen considering the available data and their international use. Each of these methods uses different parameters revealing different characteristics of the studied aquifer. Two vulnerability maps, corresponding to each method, have been obtained. The aquifer groundwater protection area could be delineated considering the mapping vulnerability assessment results.

Non-wood forest products (NWFPs) represent a veritable resource base for development, providing income to support livelihoods and promoting the competitiveness of rural economies. In Romania, NWFPs are mainly represented by forest fruits, mushrooms, game, and medicinal plants, with a total of almost 350 species of interest. Across the country the distribution of NWFPs is not uniform, being dependent on forests. The goal of this paper was to highlight the most important NWFPs for Ialomița County. Therefore, four categories of NWFPs were selected and 19 criteria were used. The Analytic Hierarchy Process (AHP) was used in order to systematically evaluate both quantitative and qualitative criteria and to assess the performance of selected alternatives (i.e. NWFPs) by means of pairwise comparisons. The analyses were carried out by the aid of the Expert Choice Desktop software. Black locust honey was the most promising non-wood forest product for Ialomița County when all the 19 selected criteria received an equal importance.

Technological and industrial evolution generated an increased demand for natural resources as well as destruction of the global biodiversity at unprecedented rates. Worldwide projections evaluate an extinction ratio of species up to10 times higher than the current rate Up to 2020 EU has establish targets for mapping and assessment of the ecosystem services including all the main stakeholders, covering forests, agro-ecosystems, freshwater and marine ecosystems, urban, arid zones and wetlands. The general mapping approaches for the EU member states involved in the process consist in using GIS instruments and work flows on land cover/land use data through ESRI’s ARCGIS Platform. About 80% of the EU member states have started the MAES process (Mapping and Assessment of Ecosystem Services) at national, regional or case-study level. The essence of the MAES process is to maximize the use of scientific knowledge and technology available in order to make a significant contribution for the ecosystem services and policy decisions to improve and protect biodiversity and life quality, as well as getting an accurate evaluation of the associated costs. The paper integrates scientific data over the MAES targets using Geographic Information Systems by the evaluation of multiple ecosystems types and services, on different temporal stages and synergies in different layers of information. Ecosystems services provide to the human kind nutrition, clean air, water, safety and healthy environment. This is why, mapping and assessing these services would allow determining the direct connections and dependency on biodiversity and its functions.

The yielding capacity is given for each maize hybrid by its genetics, but it is also influenced by the growth conditions. As drought is the main yield constraints especially in South Romania, which is the most important Romanian growing area for maize, it is of great importance for farmers but also for scientists to better understand the maize plant responses to drought under different technological conditions. The preceding crop, nitrogen rate and row spacing represent crop technology elements that the maize grower can manipulate according to his production objective, this being even more of interest in drought conditions. From this perspective, the aim of this paper is to present the results regarding the yield components and the grain yield at maize under drought and different crop technology conditions (two preceding crops, two row spacing and four nitrogen rates) in the specific growing conditions from South Romania. In this respect, a field experiment was performed in 2016 in South Romania (44029’ N latitude and 26015’ E longitude), under rainfed conditions. Five maize hybrids were studied under two preceding crops (sunflower and maize), two row spacing (70 and 50 cm) and four nitrogen rates (0 kg.ha-1; 50 kg.ha-1; 100 kg.ha-1; 50+50 kg.ha-1). Under the drought conditions of 2016, application of nitrogen and increasing of nitrogen rate from 50 to 100 kg.ha-1 increased the grain yield and values of the yield components (except TGW). Generally, grain yield and yielding components (except TGW) registered higher values at row spacing of 50 cm when the preceding crop was maize and at row spacing of 70 cm when the preceding crop was sunflower. Yielding components (except TGW) registered higher values in the case of maize as preceding crop, while TGW and grain yield registered higher values when sunflower was the preceding crop.
