A Closed Biotechnological System for the Manufacture of Nonfood Products from Cereals
1997
The production of nonfood products from agricultural raw materials is an important challenge. Efficiency of grain processing for sustainable development depends to a large extent on the harmony of the proposed system. Such a system must include consideration of all steps in the cycle from preparation of the field through cultivation of the grain crop; harvesting; total biomass utilization during processing stages; treatment of wastes; and back to preparation of the field. A closed biotechnological system can be recommended for processing of agricultural raw materials. Ethanol production from potatoes in a closed system is presented in Figure 1. Lysine production is represented schematically…

Assessment of Anthropogenic Ecological Systems in the Apold Depression to a Sustainable Management
2015
The vast majority of households in Ethiopia live in rural areas and agriculture is still the main economic activity. They rarely produce for the market and are highly dependent on climate for their subsistence. In this paper, the market options available to these farmers, as well as market related factors that are problematic were investigated. Multi-stage sampling procedure was employed to draw sample of 150 teff producers. Double hurdle model was used to identify factors affecting market participation and intensity of marketed surplus of teff. Market participation of smallholder farmers was significantly affected by access to credit, perception of farmers on lagged market price of teff, f…
Sectoral Business Cycle Synchronization in the European Union
2007
This paper analyses sectoral business cycle synchronization in an enlarged European Union using annual data for the period 1980-2005. In particular, we try to identify which sector for each country is driving the aggregate output business cycle synchronization. Overall, the sectors that provide the most relevant contribution are Industry, Building and Construction, and Agriculture, Fishery and Forestry. In contrast, the Services sector, the largest one in terms of valued added share, shows a relative low business cycle synchronization and volatility, implying that it contributes only marginally to the aggregate output business cycle synchronization.
Consumers of flowers and ornamental plants: an eploratory survey in the Italian «Mezzogiorno» regions
2010
This paper aims to provide further knowledge of purchase and consumption behaviours with regard to flowers and ornamental plants in the regions of Italian «Mezzogiorno», as an acknowledgement of the centrality of final demand in the chain process. The knowledge of consumption process is fundamental either to the firm – in order to improve commercial strategies – or to competition authorities – with the purpose of implementing more effective policies. From the analysis carried out it emerges that flowers and ornamental plants consumption in the «Mezzogiorno» regions is characterised by a high penetration index and – just with regard to some commodities – by a low purchase frequency. Purchase…
Essential oils and their applications in agriculture and agricultural products: a literature analysis through VOSviewer.
2022
In agriculture, more attention has been paid to limit the amount of chemical plant protection products. A potential alternative solution has been found in essential oils (EOs), which appear as promising candidates for their properties (safe, bioactive, biodegradable products) in managing plant diseases in agriculture. Therefore, a co-occurrence analysis was carried out on the available literature on Scopus database, through network maps created by VOSviewer software in order to identify the EOs used in agriculture, agricultural products and their target application. USA and India appeared as the most productive countries in terms of documents and citations followed by Iran and Italy. The co…
Agricultural quality products for territorial evaluation and tourism development in Sicily: the Pantelleria case
2010
The Agri-Food system is determined and conditioned by the effects of great phenomena, strictly related to territorial, environmental, social, political and economical aspects. Thus, agriculture has to carry out complex roles within the multi-functionality framework throughout production of healthy products, safeguard and protection of environment and territory, preservation and safeguard of bio-diversity, and by supplying goods and services to public, integrating with industry and agrifood distribution. Within such scenery, developed Countries, and in particular those of the EU, carry out strategies in order to adjust to new agrifood market conditions, and to respond to citizens-consumers i…
