Facing Climate Change: Urban Gardening and Sustainable Agriculture

Abstract

Measures to combat climate change encompass two primary titles: removal of the maximum greenhouse effective gases and decreasing causes of greenhouse gas emissions. The direct greenhouse gases are carbon dioxide, nitrous oxide, and methane. Nitrous oxide is approximately 300 and methane around 30 times than carbon dioxide at trapping heat in the atmosphere. Climate change affects and is affected by all communities, but its treatment must begin with the actions of individuals. Trees in the urban area strongly reduce pedestrian level heat stress by absorbing and reflecting solar irradiance. Vegetation in gardens is one of the most important components affecting climate change. Urban gardening, mainly consist of trees resource, is a valuable asset. Trees’ benefits to the human being were most pronounced in their contribution to environmental benefits. Thus, plants in gardens were found to provide a particularly important function in mitigating climate change and maintaining environmental quality of communities. Gardeners can help lessen the global warming pollutants associated with waste disposal by turning leaves, grass, woody garden clippings, and dead garden waste into mulch or compost, then using it in the garden. Recycling these wastes will not only reduce methane emissions from landfills but also improve garden’s soil and help it store carbon. One of the innovative methods that reduces greenhouse gases emissions is to make and use biochar. Because nitrous oxides is an important greenhouse gas, better management of nitrogen fertilizers can reduce its emissions. The four main management factors that help reduce nitrous oxide emissions from applied nitrogen fertilizer are commonly known as the 4R’s: right application rate; right formulation (fertilizer type); right timing of application; right placement at the plant’s root zone as possible. So, selecting right plants for urban gardens have a potential to influence Earth’s climate by altering regional and global circulation patterns and changing the amount of CO2 in the atmosphere. Also, it is important to deal with the soil to minimize the harmful impact it could cause to the environment. Planting appropriate tree species near industrial complexes is critical for aesthetic value and gases mitigation.
