What do you mean by "scarcity still exists"? Do you mean it by the way of mismanagement of basic resources or an actual lack of enough resources to go around?
No, it has nothing to do with mismanagement. It means simply, human needs and wants exceed resources.
"The
economic problem—sometimes called the
basic,
central, or
fundamental economic problem—is one of the fundamental economic theoretical principles in the operation of any
economy.[
citation needed] It asserts that there is
scarcity; that is, that the finite
resources available are insufficient to satisfy all human
wants and
needs. The question then becomes how to determine what is to be produced, and how the
factors of production (such as
capital and
labor) are to be allocated.
Economics revolves around methods and possibilities of solving this fundamental economic problem.
The economic problem arises mainly due to two facts: human wants are unlimited, but the means to satisfy human wants are scarce."

There are obviously several areas we can draw from that imply it is mismanagement.
There will always be mismanagement. It's kind of like evolution. The inept get weeded out in free markets. But not all markets are free and excessive capital accumulation leads to monopolization which is inherently inefficient if left unregulated. That is why, with the exception of legal monopolies (e.g. utilities) monopolies are at least nominally illegal. However, with big money and the influence it buys in our government, legal monopolies have been allowed to form for the sole purpose of quelling competition (e.g. sports leagues, American Medical Association, etc.) and are protected by the government.
I don't have the stats at hand but I'm pretty sure the world produces enough food for its population but it is produced in quantity enough in select places and a lot of it ends up being wasted. Add vertical hydroponic farming to the mix and we're in even better shape.
Well food scarcity in certain regions isn't so much an economic problem as it is a political problem. Corruption runs wild in many of those countries. Political leaders often steal from people who are suppose to receive food assistance. It gets back to the problem of corruption I mentioned previously.
Furthermore, I also believe land is not scarce, as the entire population of the planet can fit in an area the size of Texas. Not only that, but humans have a unique ability of taking unlivable land and turning it into an oasis. In addition, we are even capable of constructing artificial islands.
Well land is scarce in the sense that not everyone who wants land has land or can obtain land and there is relatively little unused land. If you took all the people in the world and stuck them in Texas, could they sit down? As for your assertion everyone in the world could fit into Texas you are ignoring the fact that much of Texas is uninhabitable dessert. One of the problems with your assertion is it assumes all land is inhabitable and it isn't.
The total land surface area of Earth is about 57,308,738 square miles, of which about 24% is mountainous and about 33% is desert. Subtracting this uninhabitable 57% (32,665,981 mi2) from the total land area leaves 24,642,757 square miles or 15.77 billion acres of habitable land.
"Divide this figure by the current human population of 7 billion (that's 7,000
million people!) and you get just under one hectare (2.3 acres) per person. If all the habitable land on Earth were equally distributed among all human beings present on Earth, this is the per capita share of good land per person. Again, however, we have not allowed for any nice amenities such as roads, schools, hospitals, shopping malls, rivers, lakes, reservoirs, parks, golf courses, etc. Even so, could you live on 2.3 acres?
Efforts have been made to estimate the amount of land needed to sustain an average individual human (

Yeah, land is scarce and some people use land more effectively and efficiently for a variety of reasons. As mentioned, people would have to use their 2.3 acres to produce their electricity, build their electrical appliances, roads, sewage, etc. And if you had to do all those things on your 2.3 acres of land it would be terribly inefficient.
If we convert to renewables such as solar it would be very difficult to argue that the energy output of our sun would result in energy scarcity.
Well it would be great if we could just say we are going to get our energy needs satisfied by harnessing the Sun. But it takes more than just saying you are going to harness the energy of the Sun. You need solar cell and batteries and labor to install them and then you need many days of sunshine and maintenance and replacement as parts wear out and become damaged. So unfortunately,
harnessed energy from the Sun is scarce. Because the equipment, land, and labor needed to construct devices to capture and use solar energy are scarce and expensive. So while the Sun produces "free" energy, the devices needed to capture and use that energy are not free and they are not as reliable as energy from other sources.
It seems the only thing we are legitimately scarce of and which will continue to increase in scarcity, are jobs, a central component of the free market. And the infrastructure to efficiently distribute our abundance and energy saving technology to the rest of the world.
Except, that isn't true. There is a huge gap between human needs and wants and our ability to satisfy those needs and wants and that is the fundamental economic problem, and you can't have your communist nirvana unless and until that fundamental problem is solved. Because until it is, people will always compete for those resources and if competition is allowed, there will always be some who have more and some will have less. It's a competition for scarce resources. It's why millions of people roll out of bed every day and go to work. People compete for scarce resources. It is what motivates them.
