What is Waste Management???

Waste management is a collection, transport, processing or disposal, managing and monitoring of waste materials. The term usually relates to materials produced by human activity, and the process is generally undertaken to reduce their effect on health, the environment or aesthetics. Waste management is a distinct practice from resource recovery which focuses on delaying the rate of consumption of natural resources. All wastes materials, whether they are solid, liquid, gaseous or radioactive fall within the remit of waste management.

Waste management practices can differ for developed and developing nations, for urban andrural areas, and for residential and industrial producers. Management for non-hazardous waste residential and institutional waste in metropolitan areas is usually the responsibility of local government authorities, while management for non-hazardous commercial and industrial waste is usually the responsibility of the generator subject to local, national or international controls.

Sustainability

Sustainability is the capacity to endure. For humans, sustainability is the long-term maintenance of responsibility, which has environmental, economic, and social dimensions, and encompasses the concept of stewardship, the responsible management of resource use. In ecology, sustainability describes how biological systems remain diverse and productive over time, a necessary precondition for the well-being of humans and other organisms. Long-lived and healthy wetlands and forests are examples of sustainable biological systems.

Healthy ecosystems and environments provide vital resources and processes (known as "ecosystem services"). There are two major ways of managing human impact on ecosystem services. One approach is environmental management; this approach is based largely on information gained from educated professionals in earth science, environmental science, andconservation biology. Another approach is management of consumption of resources, which is based largely on information gained from educated professionals in economics.

Human sustainability interfaces with economics through the voluntary trade consequences of economic activity. Moving towards sustainability (or applied sustainability while keeping the quality of life high is a social challenge that entails, among other factors, international and national law, urban planning and transport, local and individual lifestyles and ethical consumerism. Ways of living more sustainably can take many forms from controlling living conditions (e.g., ecovillages, eco-municipalities and sustainable cities), to reappraising work practices (e.g., using permaculture, green building, sustainable agriculture), or developing and using new technologies that reduce the consumption of resources such as renewable energy technologies.

Land Degradation

The land and soil face many difficulties like deforestation, erosion, flooding, water logging, urbanization and salination. Around 33 percent of the land is going to be wasted at the end of this century. Soil Erosion is more common in the Australia, India, Spain, U.S.A and Africa. The air and water erosion affects around 40 thousand hectares of land in a year. The top soil lost is the maximum. It makes around 20 percent of the total loss. Our country has the largest livestock and it leads to more of grazing. It leads to the soil erosion. The erosion is prevented by the crop rotation, mulching which leads to decrease in the evaporation and increase in the absorption, presence of suitable outlet channels which can carry the water, sowing of certain crops which check the erosion and include the grasses, groundnut, pulses and berseem. 
The planting of tress also checks the erosion. The control on grazing and the terracing of lands which decrease the speed of water also keeps a check on the erosion. The contour bunding has an ability to hold the rain water and control erosion. The burn agriculture along with the slash is quite common in the tribal areas. It occurs in the tropical and subtropical areas of Africa and Asia. The tress is cut and is burnt and the crops are raised on the ash formed. This phenomenon is known as jhuming and it occurs in the jhum forests in the north east India. The process is not useful as the jhuming is done frequently. The water jhuming is done in less than a decade and it destroys the forest and lead to soil erosion. 
Soil erosion affects farming in detrimental ways. Physical damage is the most visible form of soil loss, and most likely to be remedied. Gravity pulls constantly at soil, nudging it down hill, causing soil slips, earth clips, cracks, creep and slumps. Ironically, the most damaging of rainfall is the impact with which water droplets hit the soil. From there on, the flow of water causes sheet-wash, rilling, surface gullying, tunneling and in rivers it scours banks. In dry climates, wind blow is the main cause of erosion. Soil Conservation is a set of methods and procedures which are adopted for prevention of soil being eroded from the earth’s surface or becoming chemically altered by overuse or salinization or acidification. The main methodology of soil conservation are improvement of the choice of vegetative cover, soil erosion prevention, salinity management, to augment the health of beneficial soil organisms and stopping of soil contamination. Soil conservation if of utmost importance for a country like India which is mainly has an agricultural economy. A large part of India’s population depends on the soil for their livelihood and hence soil erosion and the measures of soil conservation taken up to prevent Soil erosion are of key concern for the Indian government.  

Water Crisis

The water you drink today has likely been around in one form or another since dinosaurs roamed the Earth, hundreds of millions of years ago.

While the amount of freshwater on the planet has remained fairly constant over time—continually recycled through the atmosphere and back into our cups—the population has exploded. This means that every year competition for a clean, copious supply of water for drinking, cooking, bathing, and sustaining life intensifies.

Water scarcity is an abstract concept to many and a stark reality for others. It is the result of myriad environmental, political, economic, and social forces.

Freshwater makes up a very small fraction of all water on the planet. While nearly 70 percent of the world is covered by water, only 2.5 percent of it is fresh. The rest is saline and ocean-based. Even then, just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields. In essence, only 0.007 percent of the planet's water is available to fuel and feed its 6.8 billion people.

Due to geography, climate, engineering, regulation, and competition for resources, some regions seem relatively flush with freshwater, while others face drought and debilitating pollution. In much of the developing world, clean water is either hard to come by or a commodity that requires laborious work or significant currency to obtain.
