Abstract: The Carpathians and their rich biosphere are considered to be highly vulnerable to climate change. Drought is one of the major climate-related damaging natural phenomena and in Europe it has been occurring with increasing frequency, intensity, and duration in the last decades. Due to climate change, land cover changes, and intensive land use, the Carpathian Region is one of the areas at highest drought risk in Europe. In order to analyze the drought events over the last 50 yr in the area, we used a 1961–2010 daily gridded temperature and precipitation dataset. From this, monthly 0.1° × 0.1° grids of four drought indicators (Standardized Precipitation-Evapotranspiration Index (SPEI), Standardized Precipitation Index (SPI), Reconnaissance Drought Indicator (RDI), and Palfai Aridity/Drought Index (PADI)) have been calculated. SPI, SPEI, and RDI have been computed at different time scales (3, 6, and 12 months), whilst PADI has been computed on an annual basis. The dataset used in this paper has been constructed in the framework of the CARPATCLIM project, run by a consortium of institutions from 9 countries (Austria, Croatia, Czech Republic, Hungary, Poland, Romania, Serbia, Slovakia, and Ukraine) with scientific support by the Joint Research Centre (JRC) of the European Commission. Temperature and precipitation station data have been collected, quality-checked, completed, homogenized, and interpolated on the 0.1° × 0.1° grid, and drought indicators have been consequently calculated on the grid itself. Monthly and annual series of the cited indicators are presented, together with high-resolution maps and statistical analysis of their correlation. A list of drought events between 1961 and 2010, based on the agreement of the indicators, is presented. We also discuss three case studies: drought in 1990, 2000, and 2003. The drought indicators have been compared both on spatial and temporal scales: it resulted that SPI, SPEI, and RDI are highly comparable, especially over a 12-month accumulation period. SPEI, which includes PET (Potential Evapo-Transpiration) as RDI does, proved to perform best if drought is caused by heat waves, whilst SPI performed best if drought is mainly driven by a rainfall deficit, because SPEI and RDI can be extreme in dry periods. According to PADI, the Carpathian Region has a sufficient natural water supply on average, with some spots that fall into the ''mild dry'' class, and this is also confirmed by the FAO-UNEP aridity index and the K ppen-Geiger climate classification.
Current political commitments’ challenges for ex situ conservation of plant genetic resources for food and agriculture

Abstract: This article is an overview regarding capacity building needs for supporting political commitments’ implementation and furthermore, the development of new political, technical and scientific measures for ensuring the proper conservation of biodiversity and considering in a cost-effective way ex situ conservation tools and methods. Domesticated and wild species, threatened and not threatened native species belonging to the natural capital, due to anthropic pressure and climate change may be drastically affected for their status of conservation in their ecosystems of origin. Thus, ex situ conservation is important to be taken into consideration for ensuring the proper conservation of native species. Still, ex situ conservation is a tool which is in use for many activities for many years such as: research, trade, industry, medicine, pharmaceuticals and agriculture. Romania needs to further develop its specific legislation framework in specific domains such as trade of exotic and native threatened species as well as for other domains such as zoos and aquaria, seeds exchange between botanical gardens, bioprospecting, wild threatened species rescue, capture and reintroduction, collection, access for benefit sharing. Also for agriculture should be developed ex situ conservationmeasures closely connected with breeding programmes dedicated to plant genetic resources for food and agriculture (i.e. gene banks conservation, breeding programmes, on farm conservation). Only by harmonizing at the legal level, based on science, all these specific domains, extremely sensitive, dealing with ex situ conservation it will be possible in the future to secure food and ecosanogenesis ensuring the appropriate status of in situ conservation of biodiversity as a whole. As it is not possible to apply conservation measures, either in situ either ex situ either both, to all species it is appropriate to further develop strategic tools for prioritizing our efforts in a cost effective manner.
DATA SHEET MODEL FOR DEVELOPING A RED LIST REGARDING CROP LANDRACES IN ROMANIA

Annals : Food Science and Technology , 2010,
Abstract: A data sheet model this paper is proposing that will be required for developing a future Red List for crop landraces in Romania. Such a Red List is not yet published in our country and the genetic erosion for crops is increasing especially because of the pressure of commercial crops entering the market-place and also because of the climate change and desertification as major threats. As a consequence for safeguarding food and feed it is compulsory to preserving genetic resources and a special attention should be devoted to on farm conservation. Developing a red list for crop landraces in Romania will support further on farm conservation of such crops and will more emphasize the role of gene banks in our country. Furthermore such a red list will ground the development of a new agriculture vision and policy regarding the implementation of appropriate incentive measures for supporting on farm conservation of crop landraces in specific area in Romania such is the protected area system.
Studies concerning the production of volatile oil, rhizomes and roots, to different genotypes of Valeriana officinalis L.

Analele Universitatii din Oradea, Fascicula Biologie , 2010,
Abstract: Valeriana officinalis L. is considered to pertain to European species, with great ecologic plasticity, which allows its adaptation to climate conditions characteristics to plain areas and also to mountain areas up to an altitude of 2400 meters. The species is a well-known curative plant, with a long history and multiple uses. Essential oils deriving from this species revealed the interest of researchers in food industry, cosmetics and officinal industry, furthermore being used as additives too.The raw material from which essential oils are being extracted is represented mainly by rhizomes and roots. This study has the purpose to emphasize the differences of essential oils production registered based upon the genotypes diversity. Thus, 11 experimental variants have been used, with biologic material of different origin, from Romania, Poland, Germany and Russia; they have been measured in relation to their production of rhizomes, roots and volatile oil, in the ecological conditions of Brasov, Romania.The results proved the superiority of the variants was used Romanian variety M-100, but have also revealed a negative correlation between capacity and essential oil biosynthesis.
Theoretical methodology for assessing the status of conservation of crop landraces in Romania
Maria-Mihaela ANTOFIE,Dana CONSTANTINOVICI,Mihai Radu POP,Pompilica IAGARU
Analele Universitatii din Oradea, Fascicula Biologie , 2010,
Abstract: On farm conservation of crop landraces or old traditional crops is essential for further supporting food security and new policies in relation with biodiversity conservation and climate change responses such as adaptation and mitigation. In order to improve the genetic resources knowledge regarding crop landraces’ germplasm diversity a new methodology for assessing their status of conservation thorough a landscape approach by also taking into account the climate change vulnerability of certain ecosystems compared to others and specific environment requirements is proposed. Developing new policies in applying dynamic action plans in agriculture, according to environmental factors, climate change impact and tolerance degree of crop landraces, may originate from these types of integrated studies. Based on the above mentioned rationale this proposed methodology will be further used for developing a Red List for crops in Romania.
