“…According to an estimate, more than 33 million tons of wheat is required by Pakistan to satisfy its demands in 2030 [27]; however, the production of wheat demands a multitude of energy. In previous studies, wheat production required 9.3 to 53.1 GJ ha −1 energy input under multiple experimental and treatment conditions [28][29][30]. All findings have been corroborated that the wheat production management type, characteristics of the soil, and climatic variability caused variations in the following range: 31.7-148.4 GJ ha −1 , 20.0-142.7 GJ ha −1 , 1.4-13.0, 1.99-15.8 MJ kg −1 , 60-400 kg MJ −1 , and 0.44-12.6 to energy output, net energy gains, energy use efficiency, specific energy, energy According to an estimate, more than 33 million tons of wheat is required by Pakistan to satisfy its demands in 2030 [27]; however, the production of wheat demands a multitude of energy.…”

Energy is a major component in enhancing agricultural productivity for the rapidly growing world population. From that fact, a comprehensive analysis of energy inputs and outputs is required to conserve energy for future generations without threatening the food supply. Therefore, this study was performed in wheat production across important cropping zones of Punjab, Pakistan. In this study, the energy use pattern of wheat production was analyzed, and the degrees of technical efficiency of Decision Making Units (DMUs) were examined using Data Envelopment Analysis (DEA). Based on the results of the DEA analysis, the inefficient energy inputs were identified and further explored with the core objective of a significant reduction of excess valuable resources. Data were collected from conducting a face-to-face questionnaire of 200 farmers. The farms for sample were chosen randomly by a stratified normal approach. The results disclosed that the input energy of 34,430.98 MJ ha−1 was used up for wheat production with an output energy of 48,267.05 MJ ha−1. Energy use efficiency, specific energy, energy productivity, and net energy gain in wheat production were calculated as 1.4 MJ kg−1, 9.27 MJ kg−1, 0.10 MJ kg−1 and 13,836.07 MJ kg−1, respectively. The average technical, pure technical, and scale efficiency of DMUs were 0.668, 0.776, and 0.828, respectively, and 0.74% of consulted DMUs were functioning at decreasing returns to scale. Additionally, the significant energy consumption belongs to fertilizer, and diesel fuel, which contribute 65% of the total energy input. If these inputs are applied and managed in line with ours optimize value (29,388.5 MJ ha−1) could save 14.65% resources, which will eventually add the equal quantity in wheat-yield. The total Greenhouse Gas (GHG) emissions were calculated to be 866.43 kg CO2-eq ha−1. In conclusion, the results of the present study suggest that there is sensible capacity for enhancing the energy efficiency of wheat production in Pakistan by accompanying the recommendations for economical energy management, sustainable and efficient use of energy is extremely encouraged.

“…Population and industrial growth have generated a worldwide increase of the energy demand, which has historically been met by fossil fuels, generating greenhouse gas (GHG) emissions, and making their reduction a global challenge (Karmaker et al 2020). The use of fossil fuels increases the potential for global warming, the rase of temperature and the alteration of natural ecosystem processes (Mondani et al 2017;Amin and Rahman 2019). In the last decade, an increase in the concentration of GHG has been recorded.…”

“…According to the World Meteorological Organization (WMO), the concentration reached historical values in 2016, with an atmospheric carbon dioxide (CO2) concentration growing at a record speed, showing the highest values in recent years (WMO 2019). The large emissions of GHG, especially CO2, produced by anthropogenic activities and their influence on climate conditions has become a major ecological and political challenge (Mondani et al 2017). One of the goals detailed in the United Nations Organization 2030 agenda is to guarantee access to affordable, safe, sustainable and modern energy for all, in addition to adopt measures that can fight climate change and its effects (UN 2015).…”

Advances in new technologies and ensuring a sustainable and safe energy supply, put communities in a key position to achieve the transition from conventional to renewable resources, such as geothermal energy. Perception and acceptance have a high impact on the feasibility of energy projects amongst different audiences, which is an important aspect to analyze. For this reason, this study focuses on evaluating the level of awareness and acceptance of geothermal energy within an educated segment of the population in five European and American countries (Canada, Colombia, Chile, Belgium and France) facing different stages of geothermal development. This study was conducted through an online survey, which was targeted to post-secondary students and professionals. Some of the most significant conclusions are: 1) there is a high degree of awareness of geothermal energy among the respondents in Chile and Canada, an average level in Belgium and France, and a low one in Colombia; 2) there is a favorable acceptance of a geothermal project in each country, even when hydraulic stimulation is considered; 3) environmental aspects and community safety are the most important issues that must be addressed to support a pilot geothermal project.

RESUMOA preocupação mundial acerca das mudanças climáticas motivou a elaboração de um compromisso climático, na Conferência das Partes 21 em Paris no ano de 2015. O Acordo de Paris, o qual o Brasil é signatário, prevê limitar a elevação da temperatura média do planeta em 2ºC em relação aos níveis pré-industriais. Os sistemas silvipastoris (SSP) são uma atividade incentivada pelo governo brasileiro, com potencial de mitigação estimado em 0,1360 MgC ha-1 ano-1. Dessa forma, o objetivo do presente estudo é realizar uma revisão bibliográfica sobre o potencial de estocagem e incremento de carbono em diferentes sistemas silvipastoris no Brasil, e comparar esses valores com a meta proposta na pelo país no Acordo de Paris. Para elaboração desse estudo foram levantados dados de SSP com diferentes idades, arranjos espaciais e espécies, localizados em diferentes regiões do país. O incremento médio anual em carbono encontrado nos diferentes SSP avaliados foi de 4,5613 MgC ha-1 ano-1. Esse valor é superior ao estimado pelo governo brasileiro para cumprir a sua meta de redução de emissões de gases de efeito estufa. Foi possível concluir que os SSP contribuem para a remoção de CO2 atmosférico e, portanto, devem ser incentivados para mitigação das mudanças climáticas.Palavras chave: Acordo de Paris, Integração lavoura pecuária floresta, Programa agricultura de baixo carbono. ABSTRACTGlobal concern about climate change has prompted a climate commitment at the Conference of Parties in Paris in 2015. The Paris Agreement, which Brazil is a signatory, plans to limit the rise in the planet's average temperature by 2ºC in relation to pre-industrial levels. Silvopastoral systems (SSP) are an activity encouraged by the Brazilian government, with mitigation potential estimated at 0.1360 MgC ha-1 year -1. Thus, our objective is to carry out a literature review on the potential of storage and increase of carbon in different silvipastoral systems in Brazil, and to compare these values with the goal proposed by the country in the Paris Agreement. For the preparation of this study, we performed the data collection of SSP with different ages, spatial arrangements and species, located in different regions of the country. The average annual increase in carbon found in the different SSPs evaluated was 4.5613 MgC ha-1 year -1. This figure is higher than that estimated by the Brazilian government to meet its goal of reducing greenhouse gas emissions. It was possible to conclude that SSPs contribute to the removal of atmospheric CO2 and, therefore, should be encouraged to mitigate climate change.Keywords: Agreement of Paris, Integration crop livestock and forest, Low carbon agriculture program.
