The carbon sink capacity of the world's agricultural and degraded soils is 50 to 66% of the historic carbon loss of 42 to 78 gigatons of carbon. This degradation is decreasing the long-term ability of soils to produce food. . Soil degradation has been defined as a process that leads to decline in the fertility or future productive capacity of soil as a result of human activity (United Nations Environment Programme, 1993). Building soil, sinking carbon, improving lives. If we don't act now, over 90 percent of the Earth's soils could become degraded by 2050. The alarming effect of soil degradation - majorly food insecurity and biodiversity loss - has rapidly increased for the past few years. Soil degradation, however, releases large quantities of CO2 from the soil. Humans need a sustainable way to move forward: 95% of the world food supply depends on sustainable soil function. Regions which host one-third of the world population, 45% of total agriculture land and 50% of livestock are at risk of desertification. Current information suggests that, over recent decades, soil degradation has increased and will increase further if no action is taken. These functions are worthy of protection because of their socioeconomic as well as environmental importance. Land degradationthe deterioration or loss of the productive capacity of the soils for present and futureis a global challenge that affects everyone through food insecurity, higher food prices, climate change, environmental hazards, and the loss of biodiversity and ecosystem services. . soil degradation includes physical, chemical and biological deterioration Soil Degradation and its types 4. Solutions to several problems of soil degradation in this region requiring urgent settlement are proposed. The latter effect is thought to be due to fertilisation of the growth of biomass by increasing levels of atmospheric CO2, and indeed the total amount of global biomass was observed to increase by 3.8% during the years 1981-2003. Nonetheless, 24% of the Earth's surface had occasioned some degree of degradation in the same time period. Soil degradation can have disastrous effects around the world such as landslides and floods, an increase in pollution, desertification and a decline in global food production. Food supply disruptions will become more frequent and food insecurity will rise if land degradation is not immediately reversed in favor of restoration practices such as regenerative. food security and human well-being. Yet, we are refusing to address soil degradation as. Soil Degradation: A Threat to Future Food Security Along with assessing the quantity of new land, soil quality is also a matter of concern.

Soil is a priceless, non-renewable resource that's home to thousands of animals, plants and other important organisms. on natural resources for subsistence, food security and income, including women and youth with limited adaptation options, are especially vulnerable to land degradation and climate change (high confidence). Land degradation which is also seen as a decline in land quality caused by human activities, has been a major global issue since the 20th century and it has remained high on the international agenda in the 21st century. While the degradation of natural resources has a substantial impact on the livelihood of farmers in rural areas, there is scant empirical evidence about livelihood status and benefits from communal resources, especially whether the benefits are equally distributed among local farmers. The Water-Food-Energy nexus must be expanded to the Water-Soil-Food-Energy nexus. Land degradation is the deterioration or loss of the productive capacity of the soils for the present and future. The rate of soil organic carbon sequestration with adoption of recommended technologies depends on soil texture and structure, rainfall, temperature, farming system, and soil management. In addition to providing humanity with 98.8% of its food, soils provide a broad range of other services, from carbon storage and greenhouse gas regulation, to flood mitigation and providing support for our sprawling cities. 8 June 2013 (The Daily Star) - With two centuries of an unprecedented population boom, likely to reach 9 billion by 2050, land degradation by human activities and climatic upheavals poses a threat to food security, especially in a land-scarce country like Bangladesh. This is likely to be the case into the foreseeable future as alternatives such as urban agriculture are likely to be energy inefficient and uneconomic until circular economies have developed. The production of food and feed is directly linked to the productive capacity of the soil. This study examines how the conservation of communal lands affects the food security status and the livelihood . Recent and current trends Soil health, along with water supply, is the most valuable resource for humans, as human life depends on the soil's generosity. Yet, the region is characterized by several problems including food insecurity, soil and environmental degradation, land desertification, pollution of natural waters, and loss of biodiversity. Failure to tackle land degradation will exacerbate Africa's food security worries, the report warns . Smallholders are the hardest hit by the vicious cycle of climate change, soil degradation and food security. Two predominant adverse effects of soil degradation and global warming on food security are (a) soil-water imbalance and specifically drought stress, and (b) nutrient imbalance and specifically soil infertility. This paper analyses the complexities of climate change-land degradation-food security nexus and suggests the need for adopting alternate approaches emphasising on in situ conservation of rain water and its efficient use such as to reverse the processes that contribute to land degradation in specific landscapes.

So, it is essential to combat Soil degradation at different levels and scales worldwide, not only for food security and ecological health but also for the guarantee of global sustainable development. South Asia has diverse soils, climates, physiography and other natural resources conducive to agricultural intensification. In other words, achieving food security is a challenge and maintaining it another one, and soils are an important part of the solution. Technological advances in agriculture since the 1940s have probably been masking soil degradation. Abstract Soil health, along with water supply, is the most valuable resource for humans, as human life depends on the soil's generosity. Such events as the decade are also an important reminder that even in the face of the grim statistics on world hunger, soil degradation and ecosystem loss, much work is underway to strengthen and restore nature-positive food production systems as well as soil health. Land degradation is caused by multiple forces, including extreme weather conditions, particularly drought. Soil is a limited resource and, because of the long duration of soil-forming processes, can be considered as nonrenewable. The United Nations' Intergovernmental Panel on Climate Change's (IPCC) Special Report on Climate Change and Land (SRCCL), also known as the "Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems", is a landmark study from 2019 by 107 experts from 52 countries. "The gradual degradation of soil caused by soil fertility decline and the continued exploitation of the fragile resource base depleted of many plant nutrients is a menace to rural African communities, in terms of food security, Prof Danso said, adding: "There is, therefore, a critical need to develop and implement management options that mitigate soil fertility degradation. Compost and biochar are beneficial soil amendments which derived from agricultural waste, and their application was proven to be effective practices for promoting soil fertility. The UN Secretary-General's Food Systems Summit 2021 offers a timely opportunity for countries pursuing Land Degradation Neutrality (LDN) response actions to align with the Summit's game-changing solutions, new business models, and innovative partnerships. It negatively affects food production, livelihoods, and the production and provision of other ecosystem goods and services. There is a widespread poverty and the number of food-insecure population is . A change in farming practices has never been more urgent. Soils need maintenance, but exploitation of soils has only intensified due to increasing pressure.
