Abstract
The rising population and reduction in the amount of land and some other resources have created tremendous pressure on current agricultural producers to meet the increasing food demands. To cope with this challenge, certain key inputs, such as fertilizers and other chemicals, are overused, which are worsening the surroundings. This intensive agricultural production without adherence to ecological sustainability has led to declining soil health, land degradation, and severe environmental problems. So, future efforts to feed the growing population should aim for greater agricultural production within sustainable environments. In this regard, innovative steps are needed, as business-as-usual policies lack the potential to cope with these challenges. The concept of agricultural sustainability and various soil and crop management strategies (SCMS) that have been designed to optimize crop yield under sustainable environmental conditions are discussed, including nutrient management, site specific nutrient management (SSNM), integrated nutrient management (INM), integrated soil fertility management (ISFM), integrated soil-crop system management (ISSM), ridge-furrow mulching systems (RFMS), sustainable water management (SWM), conservation agriculture (CA), sustainable land management (SLM), vertical/sky farming, and integrated crop management, and breeding strategies as well as other approaches combined with technological and behavioural changes. The present review suggests that a sustainable production system can be developed by combining the multifaceted efforts under SCMS practices with short- and long-term preventive measures. Reducing chemicals’ usage, such as that of fertilizers and pesticides, plus improvements in the crop input use efficiency could minimize greenhouse gases emissions while protecting the environment. Sustainable agriculture holds promise for humankind and the planet Earth, and it can be successful if all developed and developing nations stand together to seek ‘our common future’ to produce more food while generating less environmental pressure.

Since prehistoric times, agriculture has occupied a pivotal role in the lives of humans, considering their dependency on it for the provision of basic needs, such as food, clothing, and shelter

If the land is not allowed for grazing for rehabilitation purposes, those lacking feed will be left with no choice but to sell their livestock, and in the case of an increase in cropping intensity if new lands are to be brought under cultivation, the added workload will most probably fall on women [26]
Summary
Agriculture has occupied a pivotal role in the lives of humans, considering their dependency on it for the provision of basic needs, such as food, clothing, and shelter. Cereals, such as wheat, rice, and maize, are the major constituents of our diets that are responsible for fulfilling most of the calories that we need [1]. Modern agricultural science and molecular biology technologies have boosted the production of cereal crops over the past few decades through the development of new germplasm, but there has been evidence of yield plateaus or decreasing yield gain rates in recent years. The present study aims to review the concept of agricultural sustainability, and the various soil and crop management strategies (SCMS) that have been designed to optimize crop yield under sustainable environmental conditions
