Planted forests
1. Planted forests worldwide are increasingly important sources for forest products produced within sustainable, energy-efficient and environmentally friendly contexts. They also play a major role in preserving the social and cultural values attached to forests, particularly as natural forests decrease in size through deforestation (mainly in developing countries in the tropics and subtropics) or are designated for conservation or other purposes (mainly in developed countries in temperate zones).
2. Recently there have been concerted efforts to harmonize forest-related terms and definitions. At this point in time, it can be agreed that "planted forests" are forests in which trees have been established through planting or seeding by human intervention. Planted forests are increasingly being recognized as including semi-natural forests with indigenous species and plantation forests with exotic species.
3. Planted forests are often intensively managed for production purposes, but they may also be established for purposes of protection or conservation, or for socio-economic reasons, in which case management may be less obvious or intensive. The distinction is important for global assessments that attempt to capture the extent of productive, protective, conservational or socio-economic functions of forests, which are key criteria for sustainable forest management.

  • Planted forests worldwide are important sources for forest products, forest management is being exercised only for forests designated for sale.
  • There is no common definition of planted forests, but it has been an accepted fact that they are increasingly important nowadays.
  • Planted forests are very important in cultural and socio-economic spheres of society, the degree of forest management depending on the purpose they are planted for.

Agroforestry
1. Agroforestry is an integrated approach of using the interactive benefits from combining trees and shrubs with crops and/or livestock. It combines agricultural and forestry technologies to create more diverse, productive, profitable, healthy land-use systems.
2. In agroforestry systems, trees or shrubs are intentionally used within agricultural systems, or non-timber forest products are cultured in forest settings. Knowledge, careful selection of species and good management of trees and crops are needed to optimize the production and positive effects within the system and to minimize negative competitive effects.
3. Agroforestry systems can be advantageous over conventional agricultural and forest production methods through increased productivity, economic benefits, social outcomes and the ecological goods and services provided. Biodiversity in agroforestry systems is typically higher than in conventional agricultural systems. Agroforestry incorporates at least several plant species into a given land area and creates a more complex habitat that can support a wider variety of birds, insects, and other animals. Agroforestry also has the potential to help reduce climate change since trees take up and store carbon at a faster rate than crop.

Deforestation
1. Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a nonforest use. The term deforestation is often misused to describe any activity where all trees in an area are removed. However in temperate climates, the removal of all trees in an area – in conformance with sustainable forestry practices – is correctly described as regeneration harvest. In temperate climates, natural regeneration of forest stands often will not occur in the absence of disturbance, whether natural or anthropogenic.
2. Deforestation occurs for many reasons: trees or derived charcoal are used as, or sold, for fuel or as lumber while cleared land is used as pasture for livestock, plantations of commodities and settlements.
3. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland. Deforestation also causes extinction, changes to climatic conditions, desertification, and displacement of populations as observed by current conditions and in the past through the fossil record.

Electricity
1. Electricity is a flow of negative charges called electrons. These electric charges are measured in units called coulombs. Electricity is a very versatile form of energy that can be converted into many other forms of energy, including light and heat, direct current (DC), which flows in one direction only, and alternating current (AC), which changes direction 60 times per second.
2. An electric circuit is an unbroken conducting path from, and back to, a power supply. It has three main parts: the power supply, the conductor, and the load. The power is provided by a generator or battery, the conductor carries the current, and the load is an electric device such as a lamp.
3. Unlike current electricity, static electricity does not flow. It is created when an electrically neutral substance loses or gains electrons, making it, respectively, positively or negatively charged. You can create static electricity by rubbing a balloon on your clothing. Electrons will move from the clothing to the balloon, making the balloon negatively charged and the clothing positively charged. The resulting static electricity on each will attract small, light objects such as pieces of paper.

Electromagnetism
1. Electricity and magnetism combine to form one of the fundamental forces of the universe – electromagnetism. The two constantly interact, and the relationship between them is one of the most important in physics. For example, an electric current passing through a wire creates a magnetic field; and if the lines of force around a magnet are cut by a passing object, an electric current will be produced.
2. Magnets are attracted to iron and to any material that contains iron. Magnets have two poles, a north pole and a south pole. Unmagnetized iron and steel have magnetic regions of atoms called domains that are jumbled up and point in lots of different directions. When iron or steel becomes magnetized, the domains become aligned and they all point in the same direction. One end of each domain points toward the magnetic north pole.
3. Electronics is a new branch of physics, and one that plays an increasingly important part in our lives. It is concerned with the use of electricity to produce signals that carry information and control devices such as computers. These devices contain electric circuits through which electric current flows. The controlling parts in a circuit are called components, and these include diodes and transistors. Components can amplify currents, switch them on and off, or change their direction.
