ABSTRACT
From a public health perspective, the spread of the COVID-19 virus has become a problem. The incredible rise in disease-related infection and death rates has brought the world to a standstill in dealing with its negative consequences. This has led to a global lockdown to prevent further spread of the virus. The blockade had a huge social and economic impact. However, it also has some positive effects on the environment, especially air quality, as many research institutes point to reduced nitrogen dioxide and carbon monoxide problems in major cities (PM) around the world. Ni#trogen dioxide emissions were reduced by 20-30% in China, Italy, France and Spain, while nitrogen dioxide emissions were reduced by 30% in the United States. Compared to last year, China's air quality improved by 11.4%. NO (-77.3%), NO2 (-54.3). Compared to five years per month, 3% and carbon monoxide (-64.8%) (Signs point to a decrease) content were found during Partial shutdown in Brazil. There are about -51.84, -53.11, -17 in India 97%, -52.68, -30.35, 0.78, and -12.33 reductions in PM10, PM2 concentrations. They are SO2, NO2, CO, O3 and NH3. This article focuses on the environmental impact of closures and also discusses air pollution before and after closures in major cities around the world. Various aspects of the environment were studied and evaluated, including air, water, noise and waste management before and after closure. Therefore, this research will serve as a guide for environmentalists, leaders, and frontline activists as they look for ways to beat this disease and reduce its long-term impact on health and the environment.
ABSTRACT
Continuous cropping and frequent soil cultivation contribute to the breakdown of soil aggregates and the removal of organic matter, which reduces soil fertility and production. Green manuring is a low-cost and efficient approach for reducing the expense of inorganic fertilizers and preserving soil fertility. Due to the mounting problems facing agriculture, including climate change, extreme weather events, soil deterioration, and land contamination as a result of the overuse of chemical fertilizers, many farmers are adding green manuring into their methods to prevent soil erosion, improve soil structure, control weed growth, and most importantly increase the soil's fertility. The use of green manure has drastically decreased, raising concerns about the sustainability of soil fertility. Field crops may experience a temporary setback following the integration of organic residues with a high C-N ratio. By enhancing the soil's structure, fertility, and nutrient content, green manuring functions as a restoration factory to maintain the soil's fertility for sustainable agriculture. Green manure is therefore essential for growers that seek to decrease the use of dangerous chemicals for soil fertilization. Many farmers must use green manure in their operations to avoid the usage of chemical fertilizers in agriculture.
ABSTRACT
Forests play a critical role in combating climate change and promoting sustainable development. They are often referred to as the "lungs of the Earth" because they absorb carbon dioxide and release oxygen, making them vital for regulating the planet's climate and supporting life. Forests act as carbon sinks, absorbing and storing significant amounts of carbon dioxide from the atmosphere. Trees, through the process of photosynthesis, convert carbon dioxide into organic matter, which is stored in their biomass and in the soil. This process helps reduce the concentration of greenhouse gases, mitigating climate change. Forests are home to a vast array of plant and animal species. Biodiversity is essential for the stability and resilience of ecosystems. Maintaining healthy and diverse forests helps ensure that ecosystems can adapt to changing environmental conditions and continue to provide ecosystem services that support sustainable development. Forests contribute to climate regulation by influencing temperature, precipitation, and weather patterns. They release water vapor into the atmosphere through a process known as transpiration, which can lead to increased cloud cover and precipitation, thus affecting local and regional climates. Forests play a crucial role in protecting watersheds and maintaining the quality and availability of freshwater resources. Tree roots stabilize soil, reducing erosion and maintaining water quality. Forested areas often act as natural filters, removing pollutants and sediments from runoff. Forests provide livelihoods for millions of people worldwide, especially in rural areas. Sustainable forest management practices can ensure a steady supply of timber, non-timber forest products, and ecosystem services, contributing to the economic well-being of local communities. Forests offer various ecosystem services, including regulating services (climate regulation, water purification, erosion control), provisioning services (timber, fuelwood, non-timber forest products), cultural services (recreation, spiritual value), and supporting services (nutrient cycling, pollination). Adopting sustainable forest management practices is crucial to maintaining the benefits provided by forests. Sustainable logging, afforestation, and reforestation efforts can help maintain and even enhance the carbon sequestration capacity of forests. Recognizing and respecting the rights of indigenous peoples in forest management is essential. Indigenous communities often have valuable traditional knowledge of sustainable forest practices and can play a key role in conservation and sustainable development efforts. Efforts to restore degraded forests and establish new forested areas (reforestation and afforestation) can contribute to climate change mitigation and the protection of biodiversity. Global agreements such as the Paris Agreement and the United Nations Sustainable Development Goals (SDGs) acknowledge the importance of forests in climate action and sustainable development, providing a framework for global cooperation. In conclusion, forests are integral to addressing climate change and promoting sustainable development. Efforts to conserve and sustainably manage forests are essential to achieving environmental, social, and economic goals at both local and global levels. Recognizing the multifaceted benefits of forests and integrating them into climate and development strategies is crucial for a more sustainable and resilient future.
ABSTRACT
This comprehensive review examines the pivotal role of agroforestry in promoting soil conservation and sustainable crop production. The introduction sets the foundation by elucidating the significance of agroforestry in addressing environmental challenges and ensuring food security. Subsequent sections delve into various agroforestry practices and techniques employed for soil conservation. The review also explores the influence of agroforestry on soil properties and microbial diversity, highlighting its positive impact on soil health. Additionally, the role of agroforestry in enhancing nutrient cycling and soil fertility is discussed, showcasing its potential to improve crop productivity. The paper culminates with case studies and insights that demonstrate the successful integration of agroforestry systems to support sustainable agriculture and land management practices.
