What are agro-ecological zones?
An Agro-ecological Zone is a land resource mapping unit, defined in terms of climate, landform and soils, and/or land cover, and having a specific range of potentials and constraints for land use. An Agro-ecological Cell (AEC) is defined by a unique combination of landform, soil and climatic characterist.

20 agro-ecological zones
India has a variety of landscapes and climate conditions and this is reflected in the development of different soils and types of vegetation. Based on 50 years of climate data and an up-to-date soil database, the country has been divided into 20 agro-ecological zones (AEZs).
What is agro-ecological zone PDF?
Agro-ecological zone is a land unit, carved out of climatic zone, correlated with landforms, climate and the length of growing period (LGP). LGP refers to the number of days available for crop growth with suitable conditions.
Why is agro-ecological zone required?
Agroecological Zone land areas recognised on the basis of hydrology, physiography, soil types, tidal activity, cropping patterns, and seasons. In fact an agroecological zone indicates an area characterised by homogeneous agricultural and ecological characteristics.

What are the 5 ecological zones?
The five major Domains were Tropical, Subtropical, Temperate, Boreal and Polar. These were considered to divide the globe into five broad but ecologically valid units for global forest reporting, and the subzones provide more detailed categories where required within a broad zone.
Why do we need to study AEZ?
In this context AEZ can be regarded as a set of applications, leading to an assessment of land suitability and potential productivity in terms of climate, soil and land forms condition. Agro-Ecological Zoning (AEZ) is one of the most important bases of sustainable agricultural development planning of a region.
What is agro ecological region Upsc?
The agro-ecological region is an extension of the agro-climatic zone. The agroecological region is made up of a superimposed map of the agro-climatic zone on landforms that influence both climate and length of the growing period of crops.
