The questions of sustainable management of soil resources are shown. It is directed to the neutral level of soil degradation and agro-climatic adaptation of agriculture to climate change, promote rational use of resources, conservation and restoration of biodiversity. It is necessary to regulate the load on soils and take into account their ability to self-healing. Unbalanced use leads to a deterioration of the soil quality, water sources, loss of biodiversity, reduced environmental sustainability and ecosystem services which they provide. This question is especially actual with climate changes. Adoption of the three conventions of the United Nations is showing it. Degradation is one of the most important problems in the world. Its causes and unresolved problems of the soil resources management in Ukraine are indicated. In global climate change, the role of adaptive farming systems increases. It contributes to an increase in land productivity and sustainable use. Reducing the soil moisture content reduces mobility and availability of nutrients for plants. It requires the optimization of plant root nutrition through the mineral fertilizers. Measures for adaptation of agriculture should be integrated and cover all possible agricultural practices which can improve the plant growth. It is proposed to grow crops hybrids which resistant to temperature changes and water deficiency, to optimize the fertilizer system (by nitrogen, phosphorus, potash fertilizers, microfertilizers), moisture-saving soil cultivation systems. The use of irrigation and the expansion of irrigated land are essential for maintaining the “climate optimized” agriculture. Key words: adaptation, soil resources, degradation, fertilizers, irrigation, climate.

Rainfed agriculture is becoming increasingly vulnerable to climate change. This situation is expected to worsen under most future climate projections, which might increase the risks linked to food security and economies which depend on it. Providing insights about the potential responses of rainfed crops to climate change will helps on designing future adaptation strategies. In this study, large amount of data and the agro-hydrological model SWAT have been used to investigate future climate change impacts on rainfed wheat and sunflower crops in a semiarid watershed in Morocco (R’dom watershed). Downscaled CORDEX climate projections were used in generating future plants growth simulation for R’dom watershed in the 2031 to 2050 horizon under two Representative Concentration Pathways (RCPs): 4.5 and 8.5. The main results of climate change scenarios highlighted that R’dom watershed will undergo significant decrease in water resources availability with more impact under the scenario RCP 8.5. Water productivities of both studied crops could be lower by up to -21% in comparison with baseline situation. Different sustainable management strategies have been simulated using SWAT model under climate change context. The adopted approach succeeded in building up sustainable management strategies toward secured food security in the future.

Through advancements in technology humans have cultivated more food, used more fossil fuel reserves, polluted the environment, and caused climate change. This was not the case some few decades ago where indigenous technologies were used in exploiting natural resources. Unfortunately, the effects of climate change on the planet are no more distant reality. The melting of glaciers, rising sea levels, extreme rainfall, and prolonged drought are already being experienced. These have affected water resources, land, and food security across the world. The limits of conventional climate change adaptation and mitigation strategies call for the integration of indigenous knowledge and technologies for tackling climate change issues. This is because of the importance that indigenous knowledge and technologies have for identifying the impacts and as well providing effective adaption and mitigation strategies to climate change. Thus, this chapter explores the potential of indigenous knowledge and technologies for the sustainable management of water, land, and food security amidst climate change. The applications of indigenous technologies and knowledge such as agroforestry, the use of sacred groves to conserve water, land, and biodiversity resources, and the practising of conservation-agriculture are discussed as solutions for reducing greenhouse gas emissions, water shortages, land degradation, and pollution. However, these indigenous technologies will be less useful in today's world if not harnessed. Thus also in this chapter, the scientific know-how available to improve the effectiveness of indigenous technologies for the sustainable use of water, land, and food resources have been identified (Robotics, sensors/detectors, internet of things) and discussed.

The coronavirus disease (COVID-19) pandemic has highlighted food security issues and nutrition gaps in Asia and the Pacific, where various risks and fragilities have continually affected the food and agriculture sector. There is a clear need to integrate sustainable management of natural resources, nutritional considerations, and the economic dimensions of food supply chains to enhance resilience and mitigate climate change. This publication explores how innovative financing and transformative knowledge solutions can help address the financing gaps and other challenges of food systems in the region.
