Upland rice is grown in rainfed, naturally well-drained soils with bunded or unbunded fields without surface water accumulation. The general perception about the upland environment is that it is drought-prone, usually SLOPING land with erosion problems, and has soils with both poor physical and chemical properties. FARMERS in these environments are among the poorest and usually can not afford to apply (many) external inputs such as fertilizers. Upland rice varieties are mostly grown as a low-yielding subsistence crop to give STABLE yields under the adverse environmental conditions of the uplands. Upland rice varieties are drought tolerant, but have a low yield potential and tend to lodge under high levels of external inputs such as fertilizer and supplemental irrigation. The aerobic rice system is targeted at more favorable environments where farmers can afford to buy external inputs such as fertilizers and have access to supplementary irrigation if rainfall is not sufficient. ACHIEVING high yields under relatively favorable aerobic soil conditions requires new varieties of “aerobic rice” that combine the drought-resistant characteristics of upland varieties with the high-yielding characteristics of lowland varieties. In essence, aerobic rice can be seen as “favorable” or “high yielding” upland rice. The reason for the INTRODUCTION of a new term was the need to dissociate the envisioned relatively high-yielding production system from the general perception of extremely harsh and unfavorable conditions of “the uplands”.

Oil Conservation towards Healthy and Better EnvironmentOil conservation is the direst need of the hour. The rate at which humans have been using the fossil fuels is not only consuming future resources for the coming generations, but is also polluting our ENVIRONMENT alarmingly. The aftermath and fallout of the excessive use of fossil fuels have adversely affected man. Our environment is like a gigantic balloon of transparent life-supporting gases that are being polluted with the tar-like emissions. CONSERVING oil will not only keep the oil reserves for future generations, but will also help us conserve our environment. Let us see how reckless use of oil results in unwanted consequences.Global Warming: BURNING of fossil fuels has damaged this beautiful balloon to such an extent that reclaiming it to its pristine purity and beauty is impossibility. Man, the foolish creature, fails to see that his very existence depends on this balloon. It is a known fact that carbon dioxide, a gas released when fossil fuels are burnt, is one of the primary gases responsible for global warming. Rise in temperature of earth has resulted in melting of polar ice caps, flooding of low lying areas and rise in sea levels. If such conditions continue, our planet Earth might face some serious consequences in near future.Health Hazards:  Besides damaging the environment, air pollution caused by the emission of gases produced in burning of fuels can result in asthma, chronic obstructive pulmonary disorder, and lung cancer. Long-term exposure may increase respiratory infections in general people. Natural flora and fauna get affected with the toxic emissions that further complicate the ecological imbalance.Burden on National Economy: India is one of the largest importers of oil from foreign countries. A major chunk of our national funds get spent on oil imports. According to a data India spent USD 111.9 billion on oil imports in 2018-19. If we had some other alternative fuel for oil, we could have saved so much of our funds and spent on other developmental activities.  Future Implications: Conservation of fuel is not only the urgent need of the current times. This colossal task can be accomplished by participation of all the people. Sagacious and frugal use of fossil fuels is the direst need of the hour. The present rate at which the fossil fuels are being used is quite alarming. There won't be left anything for the coming generations. We will be called highly selfish generation, if we don't leave fuels for the future generations. We need to put our acts together. We must follow the principles of sustainable development. After all it is our responsibility to bequeath a healthy and prosperous planet. Being parents and elders it is our moral responsibility.  Exploring Alternatives for Oil Fuel: The best option in front of us at present to tackle the problems posed by fossil fuels is the option of using alternative sources of energy. The ever increasing demand for energy cannot be met by the fossil fuels. It will lead to environmental collapse as well as utter depletion. Renewable energy sources are the best bet in the scenario. And what can be a better renewable resource than the sun? Besides, it is a renewable and clean energy source. Taking both environmental and economic COST, solar energy works cheaper than fossil fuel resources. Once we master techniques to harness solar energy, it can be a vital source of power across the entire planet.Electric Vehicles: The rise in economic activity and the burgeoning population have led to a tremendous demand in the transport sector, especially in urban India. In the near future, India's urban population is expected to grow fivefold to a staggering 200 million; pollution will also grow alarmingly. With this tremendous growth has emerged a very CRITICAL issue of keeping air and noise pollution in urban areas under control. The viable solution to the above mentioned problems is the use of electric vehicles (EVs) on the roads. EVs will reduce pollution by 16 lakh metric tons. The Government must promote and encourage people to replace their pollution-causing vehicles with smart zero-emission vehicles. For this the Government must make stricter laws to protect the environment. The Government must also provide subsidy on these smart vehicles.    In conclusion it can be said that if we have to conserve our oil and save our environment. It is possible only through minimizing the use of oil and replacing the fossil fuels with alternative sources of energy. We must switch over to them as early as we can for a brighter, healthier and safer future!all the best for the competition

pls mark as brainliest Explanation:Evolution of modern humansThe origin of modern humans has probably been the most debated issue in evolutionary biology over the last few decades. Where did we come from?“The exact origin of modern humans has long been a topic of debate.Our evolutionary history is written into our . The human genome looks the way it does because of all the genetic changes that have affected our ancestors. The exact origin of modern humans has long been a topic of debate.KEY FACTModern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor,Homo erectus.Modern humans (Homo sapiens), the that we are, means ‘wise man’ in Latin. Our species is the only surviving species of the genusHomo but where we came from has been a topic of much debate. Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus, which means ‘UPRIGHT man’ in Latin. Homo erectus is an extinct species of human that lived between 1.9 million and 135,000 years ago.Historically, TWO key models have been put forward to explain the ofHomo sapiens. These are the ‘out of Africa’ model and the ‘multi-regional’ model. The ‘out of Africa’ model is currently the most widely accepted model. It proposes thatHomo sapiens evolved in Africa before migrating across the world.On the other hand, the ‘multi-regional’ model proposes that the evolution of Homo sapiens took place in a number of places over a long period of time. The intermingling of the various populations eventually led to the single Homo sapiens species we see today.“Current genomic evidence supports a single ‘out-of Africa’ migration of modern humans.This is still very much an area of active research, however, current genomic evidence supports a single ‘out-of Africa’ migration of modern humans rather than the ‘multi-regional’ model. Although, studies of the of the extinct hominids Neanderthals and Denisovans suggest that there was some mixing of genomes (1-3 per cent) with humans in Europe and Asia. This interbreeding between two previously separated populations is called ‘admixture’ and results in a mixing of between the populations. ‘Out of Africa’: what’s the evidence?‘Mitochondrial Eve’KEY FACTThere is more genetic diversity in Africa compared with the rest of the world put together.Genetic studies tend to support the ‘out of Africa’ model. The highest levels of in humans are found in Africa. In fact there is more genetic diversity in Africa compared with the rest of the world put together. In addition, the origin of modern in the mitochondria (the ‘powerhouses’ of our CELLS) has been tracked back to just one African woman who lived between 50,000 and 500,000 years ago – 'Mitochondrial Eve'.Our genomes are a combination of DNA from both our mother and father. However, mitochondrial DNA (mtDNA) comes solely from our mother. This is because the female egg contains large amounts of mitochondrial DNA, whereas the male sperm contains just a tiny amount. The sperm use their small amount of mitochondria to POWER their race to their egg before fertilisation. Once a sperm merges with an egg, all the sperm mitochondria are destroyed.KEY FACTYour mitochondrial DNA is almost exactly the same as your mother’s and her mother’s.As a result, mitochondrial DNA is described as being matrilineal (only the mother’s side survives from generation to generation). So, your mitochondrial DNA is almost exactly the same as your mother’s and her mother’s. Mitochondrial DNA has been extensively used by evolutionary biologists, as it is easier to extract than DNA found in the and there are many copies to work with.However, Mitochondrial Eve wasn’t the first or only woman on Earth at that time. She was simply the point from which all modern generations of human appear to have grown. Evolutionary biologists think the most likely reason for this is that an evolutionary ‘bottleneck’ occurred during the time Eve was alive. This is when the majority of a species suddenly dies out, perhaps due to a sudden catastrophe, bringing it to the brink of extinction. If Mitochondrial Eve was one of the few women to survive then this COULD explain why her ‘matrilineal’ mitochondrial DNA ended up being passed along so many generations.Similarly, DNA from the Y is only passed on from fathers to sons and a evolutionary tree relating all present day male individuals also supports the ‘out of Africa’ model.

Hey BUDDY here's ur ansTerracing is BUILDING flat crop fields on the slopes of HILLS so as to SLOW down the flow of WATER and checking soil erosion.

hiiiyour answer is here !Explanation:Soil pollution is defined as the presence of toxic chemicals (pollutants or CONTAMINANTS) in soil, in high enough concentrations to pose a risk to human health and/or the ecosystem. In the case of contaminants which occur naturally in soil, even when their levels are not high enough to pose a risk, soil pollution is still said to occur if the levels of the contaminants in soil exceed the levels that should naturally be present.All soils, whether polluted or unpolluted, contain a variety of compounds (contaminants) which are naturally present. Such contaminants include metals, inorganic ions and salts (e.g. phosphates, carbonates, sulfates, nitrates), and MANY organic compounds (such as lipids, proteins, DNA, fatty acids, HYDROCARBONS, PAHs, alcohols, etc.). These compounds are mainly FORMED through soil microbial activity and decomposition of organisms (e.g., plants and animals). Additionally, various compounds get into the soil from the atmosphere, for INSTANCE with precipitation water, as well as by wind activity or other types of soil disturbances, and from surface water bodies and shallow groundwater flowing through the soil. When the amounts of soil contaminants exceed natural levels (what is naturally present in various soils), pollution is generated. There are two main causes through which soil pollution is generated: anthropogenic (man-made) causes and natural causes.follow me !
