Answer:
Water is an essential constituent of healthy, productive soils. It serves to bind and secure the physical particulates in soil structure and is the medium by which natural chemicals and essential trace element nutrients are transported to plants.
I believe that what you need is to match the word with the definition. Here it is!:

urbanization
development the increase in the population of a city
sustainable
development the ability to meet current needs without
reducing the ability to meet future needs
unsustainable development
resources being used up at a faster rate than they can be replenished
overpopulation
the number of people exceeds the available natural resources in an area
Answer:
Modern irrigation systems, redirecting of streams or parts of them, and using drought resilient plants, will help gradually convert the desert and make it suitable for farming.
Explanation:
A lot of countries in the world have problems because a smaller or larger part of their territories is occupied by deserts, and on top of it, it seems like the deserts are expanding. The deserts as they are cannot really be used for anything, including farming, but this can be changed in managed properly.
In order to convert desert into land suitable for farming, a good and reliable irrigation system needs to be set up, at least for the first few decades. Ares that are relatively close and maybe have a surpluss of water, or it is a terrain where it cannot be used for farming or anything practical, the streams can be redirected toward the desert. This will bring in highly fertile sediments, a constant supply of water, and increasing humidity in the area. The plants that initially need to be used should be ones that are highly resilient to high temperatures and drought, but also leave a solid amount of biomass so that the soil can get a fertile top layer. Plants that can be very suitable are rosemary and succulents, and they will also be economically beneficial in the meantime while the transformation lasts as they can be easily sold on the market.
Answer: The acronym COVID 19 represents coronavirus disease of 2019.
Explanation:
According to some scientists agriculture was widespread in the Indian peninsula, 10000–3000 years ago, well beyond the fertile plains of the north. For example, one study reports 12 sites in the southern Indian states of [Tamil Nadu], [Andhra Pradesh]and [Karnataka] providing clear evidence of agriculture of pulses [Vigna radiata] and [Macrotyloma uniflorum], millet-grasses (Brachiaria ramosa and Setaria verticillata), wheats (Triticum dicoccum, Triticum durum/aestivum), barley (Hordeum vulgare), hyacinth bean (Lablab purpureus), pearl millet (Pennisetum glaucum), finger millet (Eleusine coracana), cotton (Gossypium sp.), linseed (Linum sp.), as well as gathered fruits of Ziziphus and two Cucurbitaceae.
Some claim Indian agriculture began by 9000 BC as a result of early cultivation of plants, and domestication of crops and animals. Settled life soon followed with implements and techniques being developed for agriculture. Double monsoons led to two harvests being reaped in one year. Indian products soon reached trading networks and foreign crops were introduced. Plants and animals—considered essential to survival by the Indians—came to be worshiped and venerated.
The middle ages saw irrigation channels reach a new level of sophistication, and Indian crops affected the economies of other regions of the world under Islamic patronage. Land and water management systems were developed with an aim of providing uniform growth.
Despite some stagnation during the later modern era the independent Republic of India was able to develop a comprehensive agricultural programme.
