“…As a result, they found out that the energy potential from residual biomass could be enough to attend the local demand there. Those cases, among others (like Portugal-Pereira et al (2015) in Brazil, Vergara et al (2020) in Colombia or Famoso et al (2020) in Italy), reveal a potential that should be explored more thoroughly, creating opportunities for diversification on the energy matrix and therefore a safer energy system in Brazil. The current agricultural production would cover around 20% of the local energy demand in the studied area.…”

In searching for sustainable solutions for humans’ necessities, clean and safe energy possibilities have been pursued. The objective of this research is to develop a procedure that improves the integration of renewable technologies into local planning processes. The methodology should be suitable for different contexts. The objective of this paper is to evaluate the potential of energy production through agricultural waste, ensuring the sustainability and development of clean technologies, the ideal allocation of the energy production unit, and the costs involved in the enterprise. The research hypothesis is that the potential for sustainable use of biomass can be identified and evaluated, thus showing the way for an improved energy plan for Brazil. The study area is within the Doce River Basin in Brazil. The methods developed in the study could be relevant for municipalities to record their potentials for energy production and pursue investments and local arrangements, promoting sustainable biomass energy generation. The results show that with proper investment, the energy generation through biomass residues could be viable and pay itself in a short amount of time, moreover in a scenario where the agricultural area is increased, growing the power generation capacity of a biomass power plant. The current agricultural production would cover 20% of the local energy demand.

Pressures on limited resources of water and energy in agriculture forced researchers to look for alternative approaches towards the solutions integrating the resources. Since the emancipation of WEF nexus concept, several methods including indicator approaches have been developed and in use to analyze their linkages. The aims of the study were to determine and categorically compare performances of sugarcane producing irrigation schemes and technologies in Awash basin of Ethiopia. Water applied, input energy used and productivity data of eleven irrigation schemes found in Wonji, Metehara and Kessem sugar factories were used for the for the study and performances of each scheme were evaluated. Then, based on statistical analyses, irrigation schemes were grouped into gravity surface, pump surface and pump sprinklers. After normalizing the original data through min-max, performance scores were determined based on equal weight and entropy methods. Categorical assessments revealed that gravity surface schemes had highest total input energy use and energy productivity scores while pump sprinkler schemes were better on water applied, Relative Irrigation Supply (RIS) and water productivity indicators. However, regarding composite performance indicators or WEF nexus indices, pump surface schemes scored the highest followed by gravity surface schemes while sprinklers were the least. The study proved the emphasis of the sugar industries of the basin for crop productivity with the expenses of energy and water utilizations. Hence, improvements on water managements of gravity surface schemes and energy utilization of sprinkler schemes were recommended as key solutions for balanced resource use as well as overall sustainability of the sector.

“…In Brazil, gains in soil nitrogen equivalent to 54 kg/ha per year from unburned cane was reported. In Brazil, where trash farming is practiced, only 60 kg of nitrogen per was applied while 150 -300 kg was used in most cane producing countries [33]. For a yield of 90 ton/ha, the nutrient in sugarcane tops and leaves is estimated to be 35.5 kg/ha of N, 7.4 kg/ha of phosphate (P 2 O 5 ) and 128.3 kg/ha of K 2 O [20].…”

Sugarcane is one of the important irrigated crops in Ethiopia and its production is highly linked with its energy and water use. In this paper, identifications and quantifications of input and output, direct and indirect energy sources, and energy use of farm operations were carried out on 11 irrigation schemes of Awash River Basin. In order to grow 91.8 to 167.6 tons of cane, 47.9 to 143.4 GJ/ha of total energy was used. Average total input energies of gravity, pump surface and sprinkler scheme categories to grow 109.8, 112.7 and 136.3 ton/ha were 53.6, 68.9 and 129.2 GJ/ha, respectively. Around 90% and 74% total energies of gravity surface and sprinkler schemes were consumed as direct and indirect energies, respectively. Irrigation found to be the most energy consuming operation constituting more than 50% input energy of all scheme categories. Energy efficiency of gravity schemes was 152% and 300% higher than pump driven surface and sprinkler schemes. Energy sequestrated in cane straws burned during harvesting found to be higher than fertilizer and pumping energy demands. Use of cane straws as manure and energy sources have the potential to substitute demands which in turn needs further investigations and analysis.
