Why Renewable Energy Gained Attention and Demand Globally?
2024
S. As’ad
Energy security and stable supply are the most important aspects for any nation. The rising need for energy, caused by both population growth and economic activity, is a problem for many nations throughout the world. Consequently, they have to find a way to meet energy demand while also making sure it is inexpensive and sustainable. The use of renewable energy has gradually become one that is being given a lot of attention since it does not cause any harm to the environment. On the other hand, renewable energy is gaining popularity for a variety of different reasons. A paradigm shift toward renewable resources is relevant, as they have the ability to lessen reliance on fossil fuels and decrease environmental consequences; this article will provide several reasons why renewable energy is attracting attention on a global scale. Indeed, renewable energy is plentiful, clean, and might one day provide all of our energy needs. A country's carbon footprint and reliance on fossil fuels may be reduced by investing in renewable energy sources. In addition, there are several health and environmental problems associated with air and water pollution; nevertheless, renewable energy may assist decrease these problems.

2024
Maninder Singh, Arshdeep Singh, Anita Jaswal and Shimpy Sarkar
There is a new method of wheat production called the System of Wheat Intensification (SWI) that manages seed treatment, seed rate, spacing, weeding, and watering. The SWI and traditional methods of wheat sowing differ from each other in terms of potential yield. In comparison to the traditional method of wheat sowing, SWI allows seed treatment, which increases the number of tillers, the number of grains in spike, and the weight of the grain. Wheat seeding in the traditional approach is done at a much closer distance than in the SWI method, which results in faulty germination as a result of increased competition between the plants. In SWI, proper root formation in the early stages of crop growth can be encouraged by increasing the space between plants and rows, as well as increasing the density of plants. For small and medium-sized farmers, it is a great way to boost productivity and income while reducing food poverty at the same time. Using organic manure instead of chemical fertilizer is a new strategy that helps support sustainable agriculture. To help the poorest farmers and enhance their productivity and profit, SWI should be recommended.

2021
Ali Mohammadipour
In line with the 2015 Paris Agreement, the present study examines the efficiency of Iran’s electricity industry compared to world standards. In 2018, Iran is ranked second in the world in terms of direct subsidies to the electricity industry, while subsidies for fossil fuels as the main feedstock for power plants are also higher. The results of the study indicate that despite the privatization of the electric industry since 2005, centralized economic management and the provision of extensive direct and indirect subsidies have led to the expansion of inefficiencies in the production and consumption of electricity. Lack of cost-based pricing is a major factor in the production of inefficient units and the determination of electricity prices at very low levels (as a result of subsidies) is the main reason for the inefficient use of electricity in Iran. The undeniable role of fossil fuels in energy production has stabilized Iran’s second-largest power plant sector in CO2 emissions in the Middle East, and as a consequence of no noticeable changes in the energy production process, the carbon intensity index and carbon intensity for electricity consumption, have fluctuated slightly. However, the energy intensity and energy intensity for electricity consumption, unlike the developed countries, have shown an upward trend, indicating a decline in energy and electrical energy efficiency in the Iranian economy. The index of fundamental reforms in electricity production, exactly the reverse of the successes in Iceland, Switzerland, Norway, Sweden and Luxembourg, is less than 8%, which is against sustainable development goals. It is crucial to take advantage of countries’ successful experiences in electricity price reform and to address the four key components proposed.

As groundwater is the primary element of life, countries all over the world are experimenting with legal reforms. The degree to which law reforms combine justice and sustainability is a crucial question. In response to this question, the present article focuses on a case study of Uttar Pradesh, India. Our response is based on a content analysis of the Uttar Pradesh Groundwater (Management and Regulation) Act, 2019, and the Uttar Pradesh Groundwater (Management and Regulation) Rules, 2020. Three conclusions emerged from our investigation. First, the 2019 Groundwater Act and the 2020 Draft Groundwater Rules are primarily motivated by concerns about resource sustainability, particularly in areas where the water table is steadily declining. Still, neither the 2019 Groundwater Act nor the 2020 Draft Groundwater Rules propose any proactive groundwater justice measures. Second, we suggest that some locally defined basic elements are critical in supporting sustainability and – to a lesser extent – groundwater justice. These characteristics include a community’s ability to (1) recognize a crisis and show a willingness to address it; (2) establish a rule-bound community groundwater resource; (3) demonstrate leadership and a sense of community; and (4) make use of awareness, information, and knowledge. Our third conclusion is that there is a need for community practices and state-led groundwater law to co-evolve; this co-evolution has the potential to create groundwater arrangements that support both groundwater justice and sustainability.

2021
Brototi Biswas and Abinada Azyu
The Himalayan region has been known as water abundant region in the form of innumerable natural water resources such as springs, streams, rivulets, etc. However, off late owing to climatic and anthropogenic reasons the entire region is soon turning into a water-deficit region leading to serious handicaps in undertaking the basic economic activities, affecting the diversity of livelihood and the drinking water sector. The problem becomes more acute in the dry season or non-monsoonal season.There seems to be a research void in the sustainable water resource planning of the Himalayan states. The present work is an attempt to study this research void through grass-root level analysis of the villages in Mizoram. Twelve villages of the Phullen RD block of Aizawl district, Mizoram were studied to understand the water supply and problems associated with water availability in the rural areas of Mizoram. In the villages of Mizoram, particularly the villages of the study area, Tuikhur or village spring source (VSS) and piped water supply constitute the main lifeline of water supply. Other sources of water include rainwater harvested and water taken from the stream or river. The springs which were once perennial have become seasonal owing to lack of spring shed management. Rainwater harvesting, barring inconsequential villages, is meagrely existent in this region of abundant rainfall with almost 130 days of rainfall. In the absence of proper water resource planning, there is a huge deficit of water every month with the average requirement of the study area being 2,49,148 gallons per month with a supply of just 2,14,248 gallons per month. However, water surplus was also observed in villages having a proper water management system in the form of rainwater harvesting and spring shed management.

2021
Muhamad Safiih Lola and Anton Abdulbasah Kamil
The present study was designed to display the integrated model of nitrogen discharge process (i.e. nitrites and nitrates; ammonia; chlorophyll and dissolved nitrogen, dissolved oxygen) which is part of the complete model of shrimp aquaculture of an Integrated Shrimp Aquaculture Park (i-Sharp) ecosystem in System Dynamic Model Aquaculture-System Policy (SD-AQEP). This study offers a comprehensive elaboration concerning the long-term process of nitrogen accumulation, as well as its effects on shrimp activities. Furthermore, the analysis of the model and the simulation results also show the conditions of nitrogen with several strategies for control and manipulation. For example, in situations where mixing of stock density is high and providing feed into ponds supplies is excessive, the nitrogen dynamic rapidly hits alarming levels. Aforementioned, the typical strategy in this setting such as stocking density and the best time to harvest could be established. Additionally, the model structure represents the discharge derived from the nitrogen process on varied settings of variables in aquaculture development. In conclusion, this model provides an experimental simulation platform that can be implemented by policy makers on long-term strategic management for developing or maintaining large-scale aquaculture development projects in the future.
