#BanSeemai Karuvela Maram - Save Former... Save Water... Save People

Now a days, TN State not able to get water from other States in India which are impacting TN formers. So, we need to refresh our water resource. Across Tamilnadu, we are seeing a tree called "Seemi Karuvelamaram" or scientific name "Vachellia nilotica" which are not good.  If you want more details about please watch this video.

Top producers in Agricultural

Food drives the world; apart from clean water, access to adequate food is the primary concern for most people on earth. This makes agriculture one of the largest and most significant industries in the world; agricultural productivity is important not only for a country's balance of trade, but the security and health of its population as well.

With that in mind, which countries produce the most agricultural products, which countries export the most, and what are countries around the world doing to increase their production levels?

Top Producers
There are numerous ways of assessing agricultural output, including sheer tonnage and the dollar volume of the commodities produced. It's important to look at both, as it is often the case that commodities critical to the food supply of less-developed countries don't show up as high dollar-value crops.

Of the major cereal and vegetable crops, the United States, China, India and Russia frequently appear as leaders. It probably won't surprise readers that China is the leading worldwide producer of rice, but it's also the leading producer of wheat and the number two producer of corn, as well as the largest producer of many vegetables including onions and cabbage. In terms of total production, the United States is third in wheat and first in corn and soybeans. 

There are other important crops, however. Millet is a major crop in much of Africa and Asia, and India and Nigeria are the leading producers. Likewise, barley, rye and beans/pulses are not that important within the United States, but are crucial crops in countries like Russia, Germany and India. Below are a few 2010 numbers based on crops and countries. 

Corn: 

Country	Production (Mt)
United States	316.2
China	177.5
Brazil	56.1

Rice: 

Country	Production (Mt)
China	197.2
India	120.6
Indonesia	66.4

Wheat:

Country	Production (Mt)
China	115.2
India	80.7
United States	60.1

Top Exporters
It should not be too surprising that countries like China and India feature prominently on the lists of top agricultural producers; these countries have large populations and internal food security (that is, producing enough to feed a nation's population from internal resources) is a major priority. A great deal of this production is used internally, though, and the list of the top exporting countries looks much different. 

Country	Exports (in billions)
United States	$118.3
Netherlands	$79
Germany	$70.8
France	$68
Brazil	$55.4

Here, again, it is important to note the difference between volume production and high-value production. The Netherlands is a tiny country; its presence on the list is to the high value of flowers and live plants (the Netherlands supply two-thirds of the global total) and vegetables (the Netherlands is a leading supplier of tomatoes and chilies). 

When it comes to the staples that feed the world (rice, corn, wheat, beans, lentils and animal proteins), countries like the United States, Germany, Canada, Brazil and Thailand feature more prominently.  

Commodity	Leading country	% of Global Exports
Corn	United States	50.1% ($9.1 billion)
Fish	China	9.2% ($6.6 billion)
Palm Oil	Indonesia	51% ($10.4 billion)
Rice	Thailand	34.5% ($6 billion)
Soybeans	United States	50.5% ($16.5 billion)
Wheat	United States	18% ($5.4 billion)

How Will the World Make More?
Almost every country wants to increase its agricultural productivity, but how they intend to go about that varies greatly with the country or region in question. 

In countries like the U.S., Canada and Western Europe, there is very little land allowed to go to waste and infrastructure like roads is well-developed. Likewise, irrigation is widespread and farmers use fertilizer extensively. This has led many countries and farmers to turn to genetically modified seeds to increase yields and reduce the need for costly (and potentially polluting) fertilizer and herbicides. 

The picture is much different in Africa and much of South Asia. In these areas, infrastructure is extremely under-developed and simply getting crops to market (or inputs like fertilizer to the farms) can be a struggle. Likewise, irrigation infrastructure is lacking, leaving farmers much more exposed to the variability of weather. Not surprisingly, then, a large focus of governments in these countries is to try to build roads, improve access to water and encourage the use of inputs, like fertilizer.

The Bottom Line
Although agriculture is no longer a major employer in North America or Europe, and food security is not a preeminent problem for most citizens, it is still a globally vital industry. As investors saw a few years ago, bad weather and low inventories quickly led the prices of many food commodities to soar and led to riots and political disturbances in many countries. On a more positive note, it's a major source of export earnings for countries across the development spectrum. 

Given the importance of agriculture and the importance of increasing yields, companies that facilitate higher production should find their products in increasing demand. Whether it's agricultural equipment like tractors, inputs like fertilizer and herbicide, or higher-yielding modified seeds, companies serving the global agriculture market have a large and still under-served market to address. 

Biggest Deserts on Earth

What is a Desert? 

A desert is a landscape or region that receives very little precipitation - less than 250 mm per year (about ten inches). Approximately 1/3 of Earth's land surface is a desert. There are four different types of deserts based upon their geographic situation: 1) polar deserts; 2) subtropical deserts, 3) cold winter deserts, and 4) cool coastal deserts. As shown on the map above, deserts occur on all of Earth's continents.

The Largest Desert 

The two largest deserts on Earth are in the polar areas. The Antarctic Polar Desert covers the continent of Antarctica and has a size of about 5.5 million square miles. The second-largest desert is the Arctic Polar Desert. It extends over parts of Alaska, Canada, Greenland, Iceland, Norway, Sweden, Finland and Russia. It has a surface area of about 5.4 million square miles.

Non-Polar Deserts 

The rest of Earth's deserts are outside of the polar areas. The largest is the Sahara Desert , a subtropical desert in northern Africa. It covers a surface area of about 3.5 million square miles. A list of the twenty largest non-polar deserts can be found below.


The Desert Environment 

When most people think of a desert they imagine a landscape covered with sand and sand dunes. Although many deserts are sand-covered, most are not. Many desert landscapes are rocky surfaces. They are rocky because any sand-size or smaller particles on the surface are quickly blown away. Rocky deserts are barren wind-swept landscapes.

Most deserts receive so little precipitation that surface streams usually only flow immediately after rainfall - unless the stream has a source of water outside of the desert. Streams that enter a desert usually suffer major water losses before they exit. Some of the water is lost to evaporation. Some is lost to transpiration (taken up by plants and then released to the atmosphere from the plants). And, some is lost to infiltration (water soaking into the ground through the bottom of the stream channel).


Desert Fauna and Flora 

The plants and animals that live in a desert must be adapted to the environment. Plants must be very tolerant to intense sun, prolonged periods without precipitation and an ability to prevent moisture loss to conditions of severe temperature ranges, dry winds and low humidity.

Animals must be able to tolerate temperature extremes, temperature ranges and have an ability to survive with very little water. Many animals adapt to desert conditions by living underground and being active at night.
