GLOBAL ENVIRONMENTAL ISSUES, CLIMATE CHANGE, FOOD SECURITY

Аннотация

The article shows that climate change is the most serious problem facing humanity: Climatechange, depletion ofwater resources and land degradation are the basis offood security, rising sea levels, increasing concentrations of SO2 in the atmosphere, increasing water scarcity anddrought. Keywords: Climate change, water resources, land degradation, food security, sea level rise, waterscarcity, drought. Introduction. Today, the world community recognizes climate change as one of the most serious problems facing humanity, the increase in the overall temperature on the Earth is one of the main indicators of environmental pollution, especially atmospheric air. Although there is no single definition of "green innovation", it is understood as the implementation of scientific research results aimed at improving people's well-being and social equality, significantly reducing environmental risks and the depletion of natural resources, and ensuring sustainable economic development while protecting the environment. It helps to achieve three goals: maintainingand increasing economic, environmental and social well-being. According to experts, a number of consequences that may occur due to climate change include rising sea levels, increasing CO2 concentrations in the atmosphere, increasing water scarcity, as well as a shortage of drinking water in the regions, a decrease in glaciers and snow cover, and anincreaseinthefrequency ofdroughts. Develop and implement economic and financial innovations, form market and price mechanisms necessary to stimulate technological innovations and create "green" jobs. It is also necessary to implement innovative policy and legal innovations, including assessing the risks associated withclimate change, and implement agricultural and "green" economy strategies. Research methodology. "Anthropogenic climate change remains one of the most important problems of our time. Its consequences are already clearly felt in Uzbekistan and throughout Central Asia. Consequences such as desertification, drought, and water scarcity are increasing. These will remain pressing problems for years to come. These issues must be addressed on an ongoing basis, including through high-quality, international-scale, and innovativeresearch." Climate change, water scarcity and land degradation are major challenges to food security. It was organized by the Government of Uzbekistan with the technical assistance of the Food and Agriculture Organization of the United Nations (FAO) and brought together more than 620 participants from 32 countries around the world. Developing countries are particularly affected. The situation is further aggravated by global climate change and reduced investment in agriculture and the food system. This puts the achievement of the Sustainable Development Goals at risk. 141 INTERNATIONAL MULTIDISCIPLINARY JOURNAL FOR RESEARCH & DEVELOPMENT SJIF2019:5.2222020:5.5522021:5.6372022:5.4792023:6.5632024:7,805 eISSN:2394-6334 https://www.ijmrd.in/index.php/imjrd Volume12,issue07(2025) Nowadays, humanity is facing the most acute global environmental problems. Solving these problems requires urgent joint efforts of international organizations, countries, regions, and the public. As a result of population growth, scientific and technological progress, and increasing human needs, a number of environmental problems have arisen on Earth. Therefore, it is difficult to talk about pure nature today. Instead of increasing, forests on Earth are shrinking, large natural areas are being converted for agriculture, and nature and air are being polluted by various wastes and gases. In addition, floods, forest fires, dust storms, and other natural processes are occurring in nature. All ofthis ultimatelydisrupts thebalance ofnature. Therefore, at the 75th session of the United Nations General Assembly, the head of our state once again drew the attention of the world community to one of the acute problems of our time - the environmental situation in the Aral Sea region, saying, among other things: "Today, every country is feeling the negative impact of this process. Unfortunately, such changes also pose a great threat to thedevelopment of Central Asia." Research result. The increase in carbon dioxide in the air and the excessive emission of exhaust gases into the air have led to thegreenhouse effect, which has led tothe emergence of a serious environmental problem that is currently worrying the world community - global climate change. In addition, environmental crises such as ozone layer depletion, pollution of the world's oceans, loss of topsoil, deforestation of tropical forests, desertification, reduction of freshwater sources and biodiversity, increase in household waste, and the neutralization of chemical and toxic substances have already gone beyond the borders of one state and have become truly global environmental problems. The issue of environmental health has developed from a national to an international scale and
