DOI:Its cultivation is possible even on marginal degraded lands that have previously been found unsuitable for growing crops. Apart from this, its ability to withstand salinity in soil and water has, to some extent, led this crop to emerge as a hardy fruit crop. It is commercially grown for its sweet-acidic fruits, which provide a cool refreshing juice… Expand.

Increases in human populations and the emerging challenges of climate change mean that the world's agricultural systems will need to produce more food in an environment that is increasingly variable and where the quality of our natural resource base is declining. One central measure of an agricultural system's capacity to do this is its ability to preserve soil organic carbon SOC , due to the pivotal role that this plays in maintaining soil physical, chemical, and biological properties and ultimately yield. This narrative review examines the literature published worldwide over the last 30 years to assess the impact of one widely applied agricultural management system, conservation agriculture CA , on its ability to maintain SOC and the subsequent impacts on soil physical, chemical and biological properties, and yield. While the effects of CA on SOC worldwide are variable, with both increases and decreases observed, in regions where soil and climatic conditions are favorable for biomass production and where the system does not negatively impact yield, then CA can lead to higher amounts of SOC relative to conventionally managed systems, particularly in the surface of the soil profile. Where greater SOC occurs, these are also often accompanied by improvements in soil structure, water infiltration and soil water storage, plant nutrient availability, microbial biomass and diversity, and yield. However, where CA is used in certain environments e.

However, agriculture in these regions are highly influenced by several factors including water limitation, extreme heat, frequent drought, bared and marginal soil, vulnerable topography for natural hazards, erosive rain and wind. In order to cope with these challenges a number of essential scientific investigation and cultural practices have continuously released, modified and recommended to sustain agriculture production in these regions. Some of these indispensable investigation and practice included that soil and water conservation, rain water harvesting and supplementary irrigation, use of stress tolerant crops and integrating of diverse farming system. So in this review it is attempted to discuss several points concerning arid and semi-arid land agricultural constraints and management action carried out to solve such constraints. Arid and semi-arid regions are characterized by hostile environmental conditions that include low and erratic rainfall, high wind velocity, intense solar radiation and high potential evapotranspiration during most parts of the year [1,2]. The situations in arid and semi-arid tropical areas are likely to have increased risks and vulnerabilities due to climate change . The main causes of the existence of these climates are the low frequency of adiabatic rise of large bodies of air and the remoteness from an oceanic source of moisture . The agriculture in these regions is facing multiple and complex challenges in terms of decline in factor productivity and the degradation of natural resources .

Agrobiodiversity is said to contribute to the sustainability of agricultural systems and food security. However, how this is achieved especially in smallholder farming systems in arid and semi-arid areas is rarely documented.
The ability to effectively maintain the functions of the ecosystem is closely related to the assessment of land resources within a conservation-utilization balance. Land degradation is one of the most significant environmental treats on arid region ecosystems in terms of the use of these resources. In this chapter, the aim was to attract the attention to land degradation processes in Turkey and analyze the current conditions in the context of policy-science interaction by performing the strengths, weaknesses, opportunities and threats SWOT analysis and develop the effective strategies for sustainable use of land resources. Thus, anthropogenic effects on sustainability of land resources and its relation with drought and productivity, and insufficient legal regulations were analyzed for developing strategies to enhance sustainability of land resources. Results showed that Turkey is at the point of breaking for sustainability of its natural resources.
Small farmers in the arid and semi-arid regions face difficulties in obtaining adequate water for agriculture. Several parts of Rajasthan, Andhra Pradesh, Gujarat, among others, are facing water shortage, increased soil salinity, low organic carbon, plastic pollution of soil, etc. Seeing the farmers struggle, it occurred to a young engineer that perhaps a simple technology for homestead-based gardening is missing in rural villages, especially in the dry areas. Refrigerators and water coolers were more popular and turning affordable. The fellowship intends to create an enabling ecosystem for innovators and entrepreneurs developing solutions for small farmers to help them become more productive, profitable, and empowered.

What are drylands and why are they important? Present in each continent and covering over 40 per cent of the earth, drylands generally refer to arid, semi-arid and dry subhumid areas, and are home to more than 2 billion people, or one in three people in the world. Drylands also support important ecosystems ranging from rangelands and grasslands to semi-desert, and host 1. Drylands, despite their relative levels of aridity, contain a great variety of biodiversity, with many animal and plant species and habitats found only in drylands and playing a vital role in the livelihoods of many dryland inhabitants IUCN,

Back to top In India's pre-independence era before the s , agriculture was a system of harnessing nature for the sustenance of human beings, similar to the presently defined organic farming. That is, Indian farmers relied on the use of crop rotation, crop residues, animal manures, legumes, green manures, off-farm organic wastes, and biological pest controls to maintain soil productivity, supply plant nutrients, and control insects, pests and other weeds on their farms.
Drylands are defined by a scarcity of water. Drylands are zones where precipitation is balanced by evaporation from surfaces and by transpiration by plants evapotranspiration. Some authorities regard hyper-arid lands as deserts United Nations Convention to Combat Desertification - UNCCD although a number of the world's deserts include both hyper-arid and arid climate zones.Drylands coverNevertheless, the United States , Australia and several countries in Southern Europe also contain significant dryland areas. Drylands are complex, evolving structures whose characteristics and dynamic properties depend on many interrelated interactions between climate , soil , and vegetation. The livelihoods of millions of people in developing countries depend highly on dryland biodiversity to ensure their food security and their well-being.
David E. In the world's semi-arid regions, high crop demands have produced short term economic incentives to convert food production on native grasslands to dryland row crop food production, while genetic enhancements and equipment have reduced the risk of crop failure. The objectives of this paper were to discuss 1 the importance of considering the long-term sustainability of changing land use in semi-arid regions; 2 the impact of extreme climatic events on ecosystem functioning; and 3 factors contributing to higher crop yields in semi-arid regions.
