“…The potential and viability of agricultural investments have to take into account land and labor costs, inputs, such as mechanical equipment costs, and income (which is linked with the market opportunities) [72]. The socioeconomic impacts can be measured via quantitative and qualitative parameters [73]. Moreover, aspects related to technological viability should also be taken into consideration.…”

This study deals with approaches for a social-ecological friendly European bioeconomy based on biomass from industrial crops cultivated on marginal agricultural land. The selected crops to be investigated are: Biomass sorghum, camelina, cardoon, castor, crambe, Ethiopian mustard, giant reed, hemp, lupin, miscanthus, pennycress, poplar, reed canary grass, safflower, Siberian elm, switchgrass, tall wheatgrass, wild sugarcane, and willow. The research question focused on the overall crop growth suitability under low-input management. The study assessed: (i) How the growth suitability of industrial crops can be defined under the given natural constraints of European marginal agricultural lands; and (ii) which agricultural practices are required for marginal agricultural land low-input systems (MALLIS). For the growth-suitability analysis, available thresholds and growth requirements of the selected industrial crops were defined. The marginal agricultural land was categorized according to the agro-ecological zone (AEZ) concept in combination with the marginality constraints, so-called ‘marginal agro-ecological zones’ (M-AEZ). It was found that both large marginal agricultural areas and numerous agricultural practices are available for industrial crop cultivation on European marginal agricultural lands. These results help to further describe the suitability of industrial crops for the development of social-ecologically friendly MALLIS in Europe.

“…This is because perennial cropping systems increase the living conditions for soil microbial communities [192], due to less soil disturbance (compared with annual cropping systems), soil organic carbon-enrichment [193], and a lower need for pesticides. This applies to most perennial bioenergy crops, such as miscanthus [163,194], switchgrass [60,195,196], giant reed [172] and willow [197,198]. Conversely, there is no information on the suitability of other perennial crops such as cup plant, Virginia mallow or wild plant species such as common tansy (Tanacetum vulgare L.), common knapweed (Centaurea nigra L.) and mugwort (Artemisia vulgaris L.) [88,122] for erosion prone sites with steep slope.…”

Prospects of Bioenergy Cropping Systems for A More Social-Ecologically Sound Bioeconomy

The growing bioeconomy will require a greater supply of biomass in the future for both bioenergy and bio-based products. Today, many bioenergy cropping systems (BCS) are suboptimal due to either social-ecological threats or technical limitations. In addition, the competition for land between bioenergy-crop cultivation, food-crop cultivation, and biodiversity conservation is expected to increase as a result of both continuous world population growth and expected severe climate change effects. This study investigates how BCS can become more social-ecologically sustainable in future. It brings together expert opinions from the fields of agronomy, economics, meteorology, and geography. Potential solutions to the following five main requirements for a more holistically sustainable supply of biomass are summarized: (i) bioenergy-crop cultivation should provide a beneficial social-ecological contribution, such as an increase in both biodiversity and landscape aesthetics, (ii) bioenergy crops should be cultivated on marginal agricultural land so as not to compete with food-crop production, (iii) BCS need to be resilient in the face of projected severe climate change effects, (iv) BCS should foster rural development and support the vast number of small-scale family farmers, managing about 80% of agricultural land and natural resources globally, and (v) bioenergy-crop cultivation must be planned and implemented systematically, using holistic approaches. Further research activities and policy incentives should not only consider the economic potential of bioenergy-crop cultivation, but also aspects of biodiversity, soil fertility, and climate change adaptation specific to site conditions and the given social context. This will help to adapt existing agricultural systems in a changing world and foster the development of a more social-ecologically sustainable bioeconomy.

“…Дослідження європейських наукових інститутів (Kayama, 2001;Al Souki et al, 2017;Fernando et al, 2018) свідчать про те, що високі концентрації важких металів пригнічувально впливають на ріст та розвиток деяких видів енергетичних культур через пошкодження коренів та зниження мінерального живлення, особливо азоту і фосфору. На противагу цьому, в польових умовах (протягом двох сезонів) інших досліджень енергетичні культури формували потужну фітомасу та високу врожайність на промислово забруднених землях (Zub & Brancourt-Hulmel, 2009;Evangelou et al, 2015).…”

Today clearing of contaminated soils from heavy metals, pesticide residues is very important problem for Ukraine. Soil pollution is considered to be the result of the functioning of metallurgical and chemical industrial enterprises, as well as the irrational application of chemical plant protection means in the agricultural sector. The range of such preparations as well as the areas of contaminated soils are increasing every year. Phytoremediation with the help of herbaceous plants is one of the most effective methods of decontamination. This list of plants should be supplemented by perennial energy crops, taking into account the absorbing powers of their root system. The basis for preparing the material was the multiple scientific literary sources of domestic and foreign scientists on an investigated theme, the workingout of relevant techniques and scientific and practical recommendations. We applied both general scientific methods (dialectics, analysis and synthesis) and special ones for conducting of analytical review of literature. The largest area of soil in Ukraine is contaminated with cobalt, molybdenum, and copper, whose content exceeds not only the background values but also the maximum permissible concentrations (MPC). It has been defined that the intensity of heavy metals transition in the system "soil-plant" of the energy crops has the following form Cd→Cu→Zn→Pb. Perennial energy crops are capable to create quickly an above ground phytomass and to form an aggressive root system that enables them to accumulate heavy metals from the soil. They can be new and important plants for phytoremediation. At the same time, the energy crops are allocated in accordance with agroclimatic zoning taking into account plant responses to the growing conditions and also applying the scheme of soil remediation from heavy metals. It has been established that energy crops (Switchgrass and Silvergrass) are Hyperaccumulators. They actively absorb heavy metals and partialy accumulate them in their underground and above ground parts. Silvergrass (Miscanthus giganteus) provides higher yield than switchgrass (Panicum virgatum), though switchgrass has less dry matter content, higher accumulation of heavy metals in plant phytomass but the maximum permissible concentration is lower than regulated standards. Silvergrass (Miscanthus giganteus) provides higher yield than switchgrass (Panicum virgatum), though switchgrass has less dry matter content, higher accumulation of heavy metals in plant phytomass and maximum permissible concentration is lower than regulated standards. On termination of the vegetation, the above-ground vegetative mass of these plants can undergo to proper processing that is an additional source of nonferrous metals or biofuel production for energy purposes.
