Name/definition
It is the most fertile soil
Alluvial
National Resources with an example.
Resources that are under the control of a nation.
e.g. canals, coal mines etc
Stock and its example
These resources have the potential to satisfy human needs, the required technical knowledge to use them is not developed.
e.g.hydrogen and oxygen in water can be a rich resource of energy. But technology to utilize them is not yet available.
Causes of soil erosion
There are two major causes.
1) Natural Causes
a) Wind erosion b) Water erosion
2) Human Causes
Deforestation, overgrazing, faulty methods of agriculture, etc.
International Resources
International resources mean the resources which belong to all the countries of the world. Example: water, seas, and oceans, etc. Oceanic resources beyond 200km of the exclusive economic zone are internationally owned resources that are regulated by international institutions
Resources on the basis of origin
Biotic
Abiotic
Fallow land
Fallow land is all arable land either included in the crop rotation system or maintained in good agricultural and environmental condition (GAEC), whether worked or not, but which will not be harvested for the duration of a crop year.
Individual Resources
Individual resources are those resources that are owned by an individual and can't be accessed by someone else. These are also referred to as private resources. These are indicators of a capitalist country and its influence.
Conservation
prevention of wasteful use of a resource.
When and where was the concept of sustainable development first formulated?
In June 1992 at the first United Nations Conference on Environment and Development in Rio-de-Janeiro.
What is a Resource?
A resource is a source or supply from which a benefit is produced and that has some utility. Resources can broadly be classified upon their availability — they are classified into renewable and non-renewable resources.
Causes of land degradation
1. Mining and quarrying
2. Waterlogging due to over-irrigation causing an increase in salinity and alkalinity
3. Overgrazing
4. Industrialization causing retardation of water infiltration into the soil.
Strip cropping
Large fields can be divided into strips. Strips of grass are left to grow between the crops.
Areas of Cotton Soil
Saurashtra, Maharashtra, Malwa, Madhya Pradesh, Chhattisgarh, and along the valleys of Godavari and Krishna rivers.
Net Swon Area
This represents the total area sown with crops and orchards. ... This represents the total area sown once and/or more than once in a particular year, i.e. the area is counted as many times as there are sowings in a year. This total area is also known as total cropped area or total area sown.
Briefly explain about Mountanious soil.
Mountain soils are generally defined as poorly developed, skeletal, shallow, acidic, and relatively infertile. They are also highly diverse and can vary significantly within limited areas due to different exposure and steepness. In general, they become less fertile and less developed as elevation increases. It is useful for cultivating spices, tea, coffee, and tropical fruits. It is found in hilly regions of J and K, Himachal Pradesh, Uttarakhand, Sikkim, Arunachal Pradesh.
Importance of Sustainable development
Sustainable development is important as it saves the national budget, fulfills the need of people, conserves natural resources, helps in the coordination between the natural resources and people, and conserves natural resources for the future generation.
Know-how
It is a term for practical knowledge in terms of expert skill, information, etc. Know-how may include tangible material ( such as formulas, instructions, marketing techniques, etc.)

Sustainable Development
Sustainable development is the idea that human societies must live and meet their needs without compromising the ability of future generations to meet their own needs.The “official” definition of sustainable development was developed for the first time in the Brundtland Report in 1987.
Features of Laterite Soil
* Low humus content
* Can be made cultivable with adequate amounts of manure and chemical fertilizers
* Useful for growing coffee, tea cashew nut, etc.
