“…Other field trials of Opuntia spp. across several semi‐arid or arid regions of the world produced mean yields that ranged from 3.5 to 5.1 Mg DM ha −1 (Grünwaldt et al, 2015; Guevara et al, 2011; Krümpel et al, 2020; Liguori et al, 2014), whereas other field trials in Ethiopia and India produced lower mean biomass yields in the range of 0.08–1.48 Mg DM ha −1 (Mangalassery et al, 2017; Soni et al, 2015; Tarekegn et al, 2017). Overall, our current results indicate that productivity of >40 Mg DM ha −1 year −1 could be accomplished without difficulty employing standard drip irrigation practices with low annual water inputs in the range of 407–716 mm.…”

“…In many countries in sub-Saharan Africa, connecting the national electricity grid is highly expensive because their populated regions are spread over vast areas. In this context, decentralized renewable energy production from DEC cultivated on marginal lands offer an attractive solution [52].

“…The Crassulacean acid metabolism is a photosynthetic adaptation that facilitates carbon dioxide uptake at night and allows prickly pear (Opuntia ficus-indica (L.) Mill.) from Cactaceae family and African milkbush (Euphorbia tirucalli L.) to grow under arid and semi-arid climates and produce biomass for methane yield of 1860 m 3 and 1791 m 3 per 1 ha of marginal land respectively [52].…”

Introduction: Nowadays, organic waste utilization and replacement of fossil energy sources with their renewable alternatives pose a challenging problem both for industrially developed and developing countries. Anaerobic digestion of organic biomass into biogas is considered an efficient technology for bioenergy production. Over the period from 2009 to 2018, the global biogas production capacities have more than doubled and are continuing to grow. The composition and the amount of biogas depend strongly on the type of the substrate. Various types of feedstock can be used for the production of biogas such as animal wastes, agricultural residues, and dedicated energy crops. Objective: To review biogas production potentials of energy crops and plant processing raw materials. Results: In the background of historical development and present state, the paper reviews the potential of different plant raw materials to be utilized for biogas production purposes. The potential of energy crops, agricultural residues, and wastes for biogas production is analyzed. International projects concerning energy crops grown on marginal lands are presented and commented on in the article. The approach of implementing crop rotation systems for industrial energy crop cultivation is described and recommended as beneficial for various purposes. The anaerobic degradability of biomass constituents, optimal process parameters, and biomass treatment for biogas production are discussed. C/N ration and lignocelluloses content in the substrate are considered among the most decisive parameters for AD and methane production. Various concepts of biogas bioreactor technologies have been studied depending on the substrate type. Conclusion: Plant feedstock may play a decisive role in biogas production as a renewable energy source. To avoid GHG release into the atmosphere, biogas facilities should be built within the closest vicinities to the places of existing garbage dumps, and waste management practice involving organic fraction separation in households and in the industry should be applied. Construction of biogas facilities is beneficial for environmental, economic, and social reasons.

“…Forage cactus is a plant with CAM (Crassulacean Acid Metabolism), a photosynthetic adaptation that facilitates the absorption of carbon dioxide at night, hence increasing water use efficiency, which enables crops to grow in arid and semiarid climates and, at the same time, produce aboveground biomass comparable to C3 and C4 crops with only 20% of water needs (Krümpel et al, 2020).…”

Variations in soil water replacement levels promote changes in forage cactus mineral composition and biomass productivity

Population growth and the need to exploit natural resources to produce food and guarantee food sovereignty reduce water availability, which can influence nutrient absorption capacity and production of plants. This study evaluated whether variations in soil water replacement levels promote changes in the mineral composition and biomass productivity of forage cactus varieties. A field experiment was conducted in a randomized block design with five levels of reference evapotranspiration replacement (25, 50, 75, 100 and 125% ETo) and three replicates. Contents of the macronutrients N, P, K, Ca, Mg and S; micronutrients Cu, Fe, Mn, Zn, Cl, Na and B; and biomass productivity were quantified in two varieties of forage cactus (‘Orelha de Elefante Mexicana’ and ‘Miúda’). The data were subjected to principal component and multivariate variance analysis. The mineral composition of the forage cactus varieties ‘Miúda’ and ‘Orelha de Elefante Mexicana’ can be optimized from soil water management, so as to obtain adequate nutritional balance for higher yield. The replacement level of 75% ETo promoted greater balance between nutrients in the cladodes of the forage cactus variety ‘Miúda’, while ‘Orelha de Elefante Mexicana’ had better nutritional balance with the replacement levels of 100 and 125% ETo. Soil water replacement levels of 100 and 125% ETo promote high accumulation of Na+ and Cl- ions in the cladodes of the forage cactus varieties studied. Highest biomass productivity of the varieties ‘Orelha de Elefante Mexicana’ and ‘Miúda’ was obtained with 75 and 100% ETo replacement levels, respectively. Among the varieties, ‘Orelha de Elefante Mexicana’ had a higher capacity for nutrient accumulation and biomass productivity, followed by ‘Miúda’, under the edaphoclimatic conditions of the Brazilian semiarid region.
