The country is known for its parks, forest and mining reserves and so good management strategies are required. Its hectares of wet dense forests make of it the second lung of the earth planet and release the oxygene that the whole planet needs its survival. For the management of that category of natural resources, forest not considered as reserves enjoy various statuses and their exploitation is regulated by many laws among which we may mention the forest code, the environment code and the law about nature conservation.
This code stipulates that civil society and the public power have access to natural resources but taking into account the protection of the world environment. In overpopulated areas, the threat of erosion is permanent while forest soils are fragile for agriculture.
With long-lasting farming we mean farming activities that aim to improve the soil maintenance by means of perennial cultures while caring for the ecological equilibrium, social and the economic operators profitability. Reforestation policy allows to reestablish soil equilibrium.
Refertilization arable soils allow to avoid erosions that carry away humus and other agricultural substances and destabilizes the configuration of the earth's layers. Sewers limit soil deterioration and tarring roads prevent cracking resulting from big engines. The soil structure deterioration has not only inconveniences but also advantages. Indeed, without erosion the amount of sand would cause decrease in the quantity of precious materials and the offer of mining products would be inelastic, which world reduce the government's in-comes and world limit social welfare.
Those resources management motivated Congolese authorities to set a mining code. The Congolese subsoil contains other mining substances almost everywhere in the country. The efficient management in the DRC mining resources is regulated by the mining code and the mining survey.
Hydraulic potential is so enormous that with Inga site alone, the DRC can provide the whole central Africa with electric energy. The major part of natural water resources is found in the overcrowded areas without any framework and without any use in lasting agriculture. In spate of such enormous water resources, desertification is drawing nearer and nearer, and necessary provisions need to be taken to protect rivers and streams in order to prevent water rarefication.
This explains why there are sub- regional organizations like the Nile basin initiative, the Congo basin organization, Organization for Tanganyika Lake biodiversity. Congolese National Parks and Fauna Reserve Management of Congolese natural resources also takes place through measuring protected areas. Even unprotected by the provision of forest code. Protected arears contain rare animal species that run the risk of extinction if protection measures are not taken.
It is localized in North Kivu province. It was crested in and it also rich in fauna and flora. Like the other ones, it is rich in fauna and flora. It was created and covers The management of Congolese national parks and reserves is dealt with by the DRC in collaboration with the World Bank because they are part of the world heritage.
Water, mining and forest resources are spread all over the country and specifically in the provinces. In each of the provinces we have natural resources which may be common or specific. Its exploitation is still performed at a small scale and by craftsmen. There are a lot of forest reserves including not only primary forests but also fallow lands which generate forests. Water resources are numerous due to the fact that a great of the Congo river in Maniema province; there is also Lomami River.
Those rivers constitute large basins favorable and the other aquatic species reproduction. In short, Maiema forest and savannas are reproduction basins for both animal and plant species that the planet needs. Mining resources and ores are also available in Maniema. In pangi territory, specifically at Kalima, there are Cassiterite and other ores. In Kailo and Kabambare we have gold and mercury; at punia ther is columbite.
There are important quantities of mining resources and ores in Maniema, which justifies the presence of SOMINKI a mining extraction firm which also operates in south-Kivu, specifically at Kamituga where similar mining resources and ores are available. Tanganyika Kivu together with Kivu lake water resources.
Kivu lake, for instance contains hydrocarbons resources, methane gaz and fish. South-kivu province green spaces also constitute important pasture lands. North-Kivu Natural Resources North-Kivu province possesses important resources, pastures lands, parks, mining resources, savannas and even more important enormous touristic potentialities.
It however, has gaz which can be exploited industrially. Vitshumbi water contains various aquatic species. Fishing is practiced at a small scate and by craftsmen, which implies a high reproduction potential for fish species. There are not many rivers in the province. Pasture lands are numerous in Masisi, Walikale and elsewhere. Virunga national park covers a part of north-Kivu green species. It contains very diversified plant and animal species.
Wood is rare, except in walikale, Beni and Lubero. This wood scarcity is even accelerated by the systematic wood exploitation resulting from a heavy demand for construction wood material in Goma town. Reforestation is practiced.
Mining resources like Cassiterite, columbite, wolfram and auxite are available throughout the province, namely, inWalikale, Masisi and Mweso areas. In the same time, the basin is facing the challenges related to rapid population growth, uncontrolled urbanisation as well as climate change.
Adequate quantification of hydrological processes across different spatial and temporal scales in the basin, and the drivers of change, is essential for prediction and strategic planning to ensure sustainable management of water resources in the Congo River Basin. Hydrological models are particularly important to generate the required information. However, the shortness of the available streamflow records, lack of spatial representativeness of the available streamflow gauging stations and the lack of understanding of the processes in channel-wetland exchanges, are the main challenges that constrain the use of traditional approaches to models development.
They also contribute to increased uncertainty in the estimation of water resources across the basin Chapter 1 and 2. Given this ungauged nature of the Congo River Basin, it is important to resort to hydrological modelling approaches that can reasonably quantify and model the uncertainty associated with water resources estimation Chapter 4 to make hydrological predictions reliable. This study explores appropriate methods for hydrological predictions and water resources assessment in ungauged catchments of the Congo River Basin.
In this context, the core modelling framework combines the quantification of uncertainty in constraint indices, hydrological modelling and hydrodynamic modelling. The latter accounts for channel-wetland exchanges in sub-basins where wetlands exert considerable influence on downstream flow regimes at the monthly time scale.
These were judged to be the minimum number of key indices that can discriminate between different hydrological responses. The constraint indices in the framework help to determine an uncertainty range within which behavioural model parameters of the expected hydrological response can be identified. Predictive equations of the constraint indices across all climate and physiographic regions of the Congo Basin were based only on the aridity index because it was the most influential sub-basin attribute Chapter 5 for which quantitative information was available.
However, it comes out of this study that the application of the original constraint indices ranges Chapter 5 generated satisfactory simulation results in some areas, while in others both small and large adjustments were required to fully capture some aspects of the observed hydrological responses Chapter 6. Part of the reason is attributed to the availability and quality of streamflow data used to develop the constraint indices ranges Chapter 5.
The main issue identified in the modelling process was whether the changes made to the original constraints at headwater-gauged sub-basins can be applied to ungauged upstream sub-basins to match the observed flow at downstream gauging stations. However, the refinement made to gauged sub-basins alone may fail to substantially affect the results if ungauged upstream sub-basins exert a major impact on defining downstream hydrological response.
The majority of gauging stations used in this analysis are located downstream of many upstream ungauged sub-basins and therefore adjustments were required in ungauged sub-basins. These adjustments consist of shifting the full range of a constraint index either towards higher or lower values, depending on the degree to which the simulated uncertainty bounds depart from the observed flow.
While this modelling approach seems effective in capturing many aspects of the hydrological responses with a reduced level of uncertainty compared to a previous study, it is recommended that the approach be extended to the remaining parts of the Congo Basin and assessed under current and future development conditions including environmental changes.
The five hydrodynamic models constructed for Ankoro, Kamalondo, Kundelungu, Mweru and Tshiangalele wetland systems have been partially validated using independent estimates of inundation extents available from Landsat imagery. Other sources of data such as remote sensing of water level altimetry, SAR images and wetland storage estimates may be used to improve the validation results.

For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2, blocks, or roughly every two weeks. When there is more computing power collectively working to mine for bitcoins, the difficulty level of mining increases in order to keep block production at a stable rate. Less computing power means the difficulty level decreases.
At today's network size, a personal computer mining for bitcoin will almost certainly find nothing. Mining hardware All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a graphics processing unit GPU or, more realistically, an application-specific integrated circuit ASIC.
Some miners—particularly Ethereum miners—buy individual graphics cards as a low-cost way to cobble together mining operations. Today, Bitcoin mining hardware is almost entirely made up of ASIC machines, which in this case, specifically do one thing and one thing only: Mine for bitcoins.
Today's ASICs are many orders of magnitude more powerful than CPUs or GPUs and gain both more hashing power and energy efficiency every few months as new chips are developed and deployed. An analogy Say I tell three friends that I'm thinking of a number between one and , and I write that number on a piece of paper and seal it in an envelope.
My friends don't have to guess the exact number; they just have to be the first person to guess any number that is less than or equal to it. And there is no limit to how many guesses they get. Let's say I'm thinking of the number There is no "extra credit" for Friend B, even though B's answer was closer to the target answer of Now imagine that I pose the "guess what number I'm thinking of" question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and Rather, I'm asking millions of would-be miners, and I'm thinking of a digit hexadecimal number.
Now you see that it's going to be extremely hard to guess the right answer. If B and C both answer simultaneously, then the system breaks down. In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer. Typically, it is the miner who has done the most work or, in other words, the one that verifies the most transactions. The losing block then becomes an " orphan block. Miners who successfully solve the hash problem but haven't verified the most transactions are not rewarded with bitcoin.
Here is an example of such a number: fcccfd95e27ce9fac56e4dfee The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet. Why is that? To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal. This, in turn, means that every digit of a multi-digit number has possibilities, zero through In computing, the decimal system is simplified to base 10, or zero through nine.
In a hexadecimal system, each digit has 16 possibilities. But our numeric system only offers 10 ways of representing numbers zero through nine. If you are mining Bitcoin, you do not need to calculate the total value of that digit number the hash. I repeat: You do not need to calculate the total value of a hash. Remember that analogy, in which the number 19 was written on a piece of paper and put in a sealed envelope?
In Bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash. What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. Miners make these guesses by randomly generating as many " nonces " as possible, as quickly as possible. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep mentioning. In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits.
The first miner whose nonce generates a hash that is less than or equal to the target hash is awarded credit for completing that block and is awarded the spoils of 6. In theory, you could achieve the same goal by rolling a sided die 64 times to arrive at random numbers, but why on Earth would you want to do that? The screenshot below, taken from the site Blockchain. You are looking at a summary of everything that happened when block No.
The nonce that generated the "winning" hash was The target hash is shown on top. The term "Relayed by AntPool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools more about mining pools below. As you see here, their contribution to the Bitcoin community is that they confirmed 1, transactions for this block. If you really want to see all 1, of those transactions for this block, go to this page and scroll down to the Transactions section.
Source: Blockchain. All target hashes begin with a string of leading zeroes. There is no minimum target, but there is a maximum target set by the Bitcoin Protocol. No target can be greater than this number: ffff The winning hash for a bitcoin miner is one that has at least the minimum number of leading zeroes defined by the mining difficulty.
Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner: Note: These are made-up hashes. Mining pools are comparable to Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings. A disproportionately large number of blocks are mined by pools rather than by individual miners.
In other words, it's literally just a numbers game. You cannot guess the pattern or make a prediction based on previous target hashes. At today's difficulty levels, the odds of finding the winning value for a single hash is one in the tens of trillions. Not great odds if you're working on your own, even with a tremendously powerful mining rig. Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem, but they must also consider the significant amount of electrical power mining rigs utilize in generating vast quantities of nonces in search of the solution.
All told, Bitcoin mining is largely unprofitable for most individual miners as of this writing. The site CryptoCompare offers a helpful calculator that allows you to plug in numbers such as your hash speed and electricity costs to estimate the costs and benefits. The miner who discovers a solution to the puzzle first receives the mining rewards, and the probability that a participant will be the one to discover the solution is equal to the proportion of the total mining power on the network.
Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own. For instance, a mining card that one could purchase for a couple of thousand dollars would represent less than 0. With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse.
The miner may never recoup their investment. The answer to this problem is mining pools. Mining pools are operated by third parties and coordinate groups of miners. By working together in a pool and sharing the payouts among all participants, miners can get a steady flow of bitcoin starting the day they activate their miners. Statistics on some of the mining pools can be seen on Blockchain. A Pickaxe Strategy for Bitcoin Mining As mentioned above, the easiest way to acquire Bitcoin is to simply buy it on one of the many Bitcoin exchanges.
Alternately, you can always leverage the "pickaxe strategy. To put it in modern terms, invest in the companies that manufacture those pickaxes. In a cryptocurrency context, the pickaxe equivalent would be a company that manufactures equipment used for Bitcoin mining. Downsides of Mining The risks of mining are often financial and regulatory. As aforementioned, Bitcoin mining, and mining in general, is a financial risk because one could go through all the effort of purchasing hundreds or thousands of dollars worth of mining equipment only to have no return on their investment.
That said, this risk can be mitigated by joining mining pools. If you are considering mining and live in an area where it is prohibited, you should reconsider. It may also be a good idea to research your country's regulation and overall sentiment toward cryptocurrency before investing in mining equipment. One additional potential risk from the growth of Bitcoin mining and other PoW systems as well is the increasing energy usage required by the computer systems running the mining algorithms.
Though microchip efficiency has increased dramatically for ASIC chips, the growth of the network itself is outpacing technological progress. As a result, there are concerns about Bitcoin mining's environmental impact and carbon footprint. There are, however, efforts to mitigate this negative externality by seeking cleaner and green energy sources for mining operations such as geothermal or solar sources , as well as utilizing carbon offset credits.
Switching to less energy-intensive consensus mechanisms like proof-of-stake PoS , which Ethereum has transitioned to, is another strategy; however, PoS comes with its own set of drawbacks and inefficiencies, such as incentivizing hoarding instead of using coins and a risk of centralization of consensus control.
Mining is a metaphor for introducing new bitcoins into the system because it requires computational work just as mining for gold or silver requires physical effort. Of course, the tokens that miners find are virtual and exist only within the digital ledger of the Bitcoin blockchain. Because they are entirely digital records, there is a risk of copying, counterfeiting, or double-spending the same coin more than once.
Mining solves these problems by making it extremely expensive and resource-intensive to try to do one of these things or otherwise "hack" the network. Indeed, it is far more cost-effective to join the network as a miner than to try to undermine it. How Does Mining Confirm Transactions? In addition to introducing new BTC into circulation, mining serves the crucial role of confirming and validating new transactions on the Bitcoin blockchain.
This is important because there is no central authority such as a bank, court, government, or anything else determining which transactions are valid and which are not.
