Non-profit Organization
A nonprofit organization (NPO) or non-profit organisation, also known as a non-business entity, not-for-profit organization, or nonprofit institution, is a legal entity organized and operated for a collective, public or social benefit, in contrast with an entity that operates as a business aiming to generate a profit for its owners. A nonprofit is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. An array of organizations are nonprofit, including some political organizations, schools, business associations, churches, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be tax-exempt, and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as a nonprofit entity without securing tax-exempt status. Key aspects of nonprofits are accountability, trustworthiness, honesty, and openness to eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Groundwater Pollution
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater. This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution. Groundwater pollution can occur from on-site sanitation systems, landfill leachate, effluent from wastewater treatment plants, leaking sewers, petrol filling stations, hydraulic fracturing (fracking) or from over application of fertilizers in agriculture. Pollution (or contamination) can also occur from naturally occurring contaminants, such as arsenic or fluoride. Using polluted groundwater causes hazards to public health through poisoning or the spread of disease (water-borne diseases). The pollutant often creates a contaminant plume within an aquifer. Movement of water and dispersion within the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Market Forces
In economics, a market is a composition of systems, institutions, procedures, social relations or infrastructures whereby parties engage in exchange. While parties may exchange goods and services by barter, most markets rely on sellers offering their goods or services (including labour power) to buyers in exchange for money. It can be said that a market is the process by which the prices of goods and services are established. Markets facilitate trade and enable the distribution and allocation of resources in a society. Markets allow any tradeable item to be evaluated and priced. A market emerges more or less spontaneously or may be constructed deliberately by human interaction in order to enable the exchange of rights (cf. ownership) of services and goods. Markets generally supplant gift economies and are often held in place through rules and customs, such as a booth fee, competitive pricing, and source of goods for sale (local produce or stock registration). Markets can differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millennium Villages Project
The Millennium Villages Project (MVP) was a demonstration project of the Earth Institute at Columbia University, the United Nations Development Programme, and Millennium Promise aimed at proving that its integrated approach to rural development can be used to achieve the Millennium Development Goals—eight globally endorsed targets that address the problems of poverty, health, gender equality, and disease—by 2015. Even though the website of the Millennium Village Project is still active, the project ended with final evaluation in 2015 because it was initially scaled to progress for a decade from 2005. The project was divided into two phases, from 2004-2010 for the first phase and 2011-2015 for the second phase. In the first phase, the project was focused at the following five stations: agriculture (seed and fertilizer support, farmer training and storage expansion, crop diversification, etc.), health (installation of mosquito nets, vaccine supply and pest control, etc.), educa ...

Subsidies In India
The Indian government has, since war, subsidised many industries and products, from fuel to gas. Kerosene subsidy was introduced during the 2nd Five Year Plan (1956–1961) and since 2009 slowly decreased until 2022 when it was eliminated. Introduction A subsidy, often viewed as the converse of a tax, is an instrument of fiscal policy. Derived from the Latin word 'subsidium', a subsidy literally implies coming to assistance from behind. However, their beneficial potential is at its best when they are transparent, well targeted, and suitably designed for practical implementation. Subsidies are helpful for both economy and people as well. Subsidies have a long-term impact on the economy; the Green Revolution being one example. Farmers were given good quality grain for subsidised prices. Likewise, we can see that how the government of India is trying to reduce air pollution to subsidies lpg Like indirect taxes, they can alter relative prices and budget constraints and thereby ...

Tensiometer (soil Science)
A tensiometer in soil science is a measuring instrument used to determine the matric water potential (\Psi_m) ( soil moisture tension) in the vadose zone. This device typically consists of a glass or plastic tube with a porous ceramic cup and is filled with water. The top of the tube has either a built-in vacuum gauge or a rubber cap used with a portable ''puncture tensiometer'' instrument, which uses a hypodermic needle to measure the pressure inside the tensiometer. The tensiometer is buried in the soil, and a hand pump is used to pull a partial vacuum. As water is pulled out of the soil by plants and evaporation, the vacuum inside the tube increases. When the soil is wetted flow can also occur in the reverse direction: as water is added to the soil, the vacuum inside the tube pulls moisture from the soil and decreases. When the water pressure in the tensiometer is determined to be in equilibrium with the water pressure in the soil, the tensiometer gauge reading represents ...

Overdrafting
Overdrafting is the process of extracting groundwater beyond the equilibrium yield of an aquifer. Groundwater is one of the largest sources of fresh water and is found underground. Groundwater depletion is comparable to a bank account in which more money is withdrawn than deposited. The primary cause of groundwater depletion is the excessive pumping of groundwater up from underground aquifers. There are two sets of yields: safe yield and sustainable yield. Safe yield is the amount of groundwater that can be withdrawn over a period of time without exceeding the long-term recharge rate or affecting the aquifer integrity. Sustainable yield is the amount of water extraction that can be sustained indefinitely without negative hydrological impacts, taking into account both recharge rate and surface water impacts. There are two types of aquifers: confined and unconfined. In confined aquifers, there is an overbearing layer called aquitard, which contains impermeable materials through wh ...
