Meat processing is an important sector of the food industry, which has a special impact on increasing the competitiveness of the national economy, but also on ensuring the food security of Romania. The tradition of raising animals and the processing of agri-food raw materials can ensure the need for raw materials, satisfying the internal consumption, but also making income for the meat processing company in Romania. The meat market, at national level, is in deficit, being dependent on meat imports, while on the export live animals are valued, with a low added value. The purpose of this paper is to highlight the current situation in the meat processing sector in terms of production, consumption per capita and meat imports and exports, comparing with the number of meat processing units. The study highlights the decrease in domestic meat production of poultry, pigs and cattle, except for the production of sheep and goats that is increasing, between 2015 and 2017, where in beef production decreased by 18.99%, pork production decreased by 3.85%, poultry meat production decreased by 4.58%, and in sheep and goat meat production increased by 5.86%. Imports of meat from the analyzed species are increasing, also the consumption of meat per capita is increasing, but also the companies in the field of meat processing are increasing.

Two important intelligent tools were used in the present paper: low temperature ashing (LTA) and SEM-EDAX to investigate qualitatively and quantitatively the redox features generated by the soil biodiversity activity as an important provider of ecosystem services. The LTA was applied on uncovered soil thin sections to „ashing‟, in situ, organic components, in order to qualitatively identify the organic components from the mineral ones, as well as their spatial distribution into the dark amorphous redox features. The SEM-EDAX was used to quantitatively identify (in situ in soil thin sections) the constituents of the dark amorphous redoximorphic features, before and after LTA treatment. The soil is a drained Gleysol with mollic epipedon, formed in the alluvial stratified deposits. Oriented uncovered soil thin sections were analyzed and treated following the sequence: micromorphological study  LTA treatment  SEM-EDAX micro-analysis. The results of the micromorphological observation emphasize the presence of many types of redoximorphic features, which appear in plain polarized light as black amorphous redox concentrations. While in the oblique light, the Fe features clearly distinguish by their reddish colour, whereas the Mn and the organic matter showed black colours. During the LTA treatment, the black organic matter was oxidized (with the minimum disturbance of the thin section) revealing the presence of mineral compounds. In contrast to the micromorphological observation and despite of the very spread blackish features (which could suggest high quantities of Mn), the SEM-EDAX micro-analysis had been detected only few percent of Mn. In this respect the combined use of the intelligent tools (LTA and SEM-EDAX) proved to be a valuable technique for in-situ investigation (on thin sections) of the amorphous redox features generated under aquic conditions, by the biodiversity as an ecosystem services provider.

The concept of smart forest is rather recent, being adapted from the climate smart agriculture concept, which has appeared in 2010. The forest situated in this category should fulfill the following criteria: increased income and productivity, improved resilience and reduces greenhouse gases. In addition, climate-smart forestry in mountain regions tries to situate forests from the mountain area based on their adaptation towards climatic changes, carbon stocks, biodiversity or other synthetic indices. The present article tries for the first time the framing of alder forests from the Southern Carpathian Mountains based on 16 indices regarding their site and stand characteristics. Alder stands from this area are generally located on plain fields, at low altitudes and on average or superior bonity stations. However, only 3.6% of them can be situated in the smart forest category. These stands are indicated on humid and rich soils, while their exploitation should be realized when they reach an age of 60-70 years
