C. C. Iwuji, O. C. Okeke, B. C. Ezenwoke, C. C. Amadi, H. Nwachukwu
Engineering (ENG) , 2016, DOI: 10.4236/eng.2016.81003
Abstract: Earth resources are the essential basis for an economy of a country and well-being of her citizens. Their exploitation is a key factor in economic growth and development of the nation, but one that can have serious negative environmental and socio-economic impacts. Therefore it is important to understand their origin/occurrence and exploitation in terms of environmental sustainability. The human society has profited from exploitation of earth resources, precisely when energy use became much more efficient during the industrial era. Some of these earth resources (renewable and non-renewable) are oil and gas, coal, water, metal ore, wind, air etc. and their methods of exploitation are surface and subsurface mining methods [1]. Thus the geological perspectives of earth resources refer to origin and occurrence of these earth resources while the engineering perspectives refer to the processes involved in the extraction (mining), processing and utilization of the resources. To fulfill the requirement of sustainable development, the efficiency with which resources are utilized has to be improved. The main concerns associated with earth resources, therefore, are generally the costs and environmental impacts of extracting, transporting, and refining them. The economics of earth resources deals with the supply, demand and allocation of the resources.

The development of Brazilian agriculture: future technological challenges and opportunities
Pedro Pereira, Geraldo B Martha, Carlos AM Santana, Eliseu Alves
Agriculture & Food Security , 2012, DOI: 10.1186/2048-7010-1-4
Abstract: Ensuring food security has always been a priority issue for governments, international organizations, and society in general. Recent developments have further increased the political, professional, and public concern about this issue worldwide. After remaining at historically low levels for decades, nominal food prices have become substantially higher and more volatile since the 2007 to 2008 food crisis. Between January 2007 and June 2008, food prices increased significantly, ranging from 38% for sugar to 224% for rice [1]. Prices for other major food crops such as maize and wheat also experienced sharp spikes in the same period. Following this period of steep rises, the prices of these and other agricultural commodities experienced a downturn in the second half of 2008.From the second half of 2010, food prices increased again, and peaked in January 2011. Through the course of 2011, a downward trend was re-established, but prices are still at historically high levels (Figure1). Depending on how world production evolves in the next years, nominal food prices could remain at or even above the 1997 to 2006 level [2,3].The consequences of higher prices and volatility in food markets are well documented in the literature, and include economic and political instability as well as cycles of positive and negative effects on consumers and producers. At high prices, increased poverty and malnutrition among the poor can be expected, but this trend for higher prices may also enhance investments in agricultural activities [4]. With increased supply, food prices decrease, benefiting consumers; however, excessive volatility may discourage longer-term investment in agriculture, and hence jeopardize an expansion in agricultural supply.The degree of future volatility in the food system is uncertain. Therefore, efforts are needed to minimize high levels of volatility in global food markets and ensure food security for all. The nature of this challenge requires country-level actions on

Abstract: Although physical geography has a long tradition, its faster development started since the establishing of Geography Institute in 1893. At first geomorphology was developed, then climatology, mathematical geography and hydrology and much later biogeography and paleogeography. In the past period, the schedule of physically geographical subjects didn't change much but as for scientific development, physical geography is in constant ascent. Through basic and graduate studies, it trains young geography staff for scientific research, but also for practical work in various fields of social life.

Abstract: Apart from very contaminated spatial areas, there are places with attractive and non-polluted environment, that are suitable for tourism and recreation. Such places are spa resorts, characterized by numerous and various natural elements having significant health and recreative functions (thermo-mineral springs, rare gases, favorable climatic conditions, rich vegetation, etc.), which attract attention of ample tourist demand. Serbia is welknown as a 'country of spa resorts', because of a great number of thermo-mineral springs, long tradition and their significance for tourism economy. Official statistical service keeps records of tourist flows only at 30 spa resorts (approximately), having participation at 95% of the total tourist trade in Serbia's spas. The topic of this paper is devoted to estimation of the present state and perspectives of spa tourism in Serbia. Special attention is focused on: analysis of resources for spa tourism, discussion of key factors for tourist valorization of Serbia's spas, investigation of structural features of spa tourism, comparison of Serbia's experiences in domain of spa tourism with contemporary trends in certain spa resorts in other European countries, and, finally, defining the most important tasks for spa tourism improvement.

Abstract: The way crossed by the Romanian banking system until the present time is one governed by profound reforms which have been made in regards to the European Union. The strategies embraced by Romanian banks, in 1990 and until the present time, are meant to develop and to improve the performances so that they can compete with European banks and they can respond in an efficient manner to the customersa€ needs. The purpose of this paper is to underline the main stages of evolution of the Romanian banking system since 1990 and to lay emphasize the perspectives on its evolution in the context of the actual economic crisis. By going through the stages previously mentioned in this paper , we can see that the Romanian banking system evolved positively, from the moment of the transition to the market economy, but in order for it to be functional and to contribute to the development of the economy as a whole, aspects related to the the supervision of the financial stability should be taken into consideration and in order to assure the stability of the financial system, the increase of the administrative capacity of the Central Bank should be considered, as well as balancing the structure of the creditation process, on coins, the improvement of the banking assetsa€ quality, the qualitative study of the NBRa€ s surveillance process, managing the contagion risk, etc. In order to achieve these objectives, the documentation by the investigation of a significant volume of works has been done, by scientifically acknowledged publications, analysis being applied, by deduction method and a significant volume of quantitative information was submitted to professional judgment. Concerns regarding this subject have been found in various paper works and in specialized books. We mention here the doctoral thesis of Elena Teodorescu Georgescu a€ The evaluation pattern of credit institutionsa€ prudential surveillance efficacya€ , the author of this work David Delia, with the work a€ Contributions regarding the improvement of the banking accountancy dealing with credits granted to non-financial clientsa€ and so on.
