1. Orientation on Agro-ecosystem analysis (AEA) Pradip K. Neog

2. Agro-ecosystem
Land used for crops, pasture, and livestock; the adjacent uncultivated land that supports other vegetation and wildlife; and the associated atmosphere, the underlying soils, groundwater, and drainage networks.

3. An agroecosystem is the basic unit of study for an agro-ecologist
An agroecosystem is the basic unit of study for an agro-ecologist. It is somewhat arbitrarily defined as a spatially and functionally coherent unit of agricultural activity, and includes the living and nonliving components involved in that unit as well as their interactions.
As the name implies, at the core of an agro-ecosystem lies the human activity of agriculture.

4. Agroecosystem analysis is a thorough analysis of an agricultural environment which considers aspects from ecology, sociology, economics, and politics with equal weight.

5. Agro-ecosystem analysis (AEA) is a methodology for zoning and analysing agricultural systems in order to plan and prioritise research and development activities in the fields of agriculture and natural resource management. .

6. AEA uses a holistic or systems approach to gather bio-physical and socio-economic information within the ecosystem along with key issues, strengths, weaknesses, limitations, problems and prospects/opportunities that are useful for rural development, extension and research programmes

7. AEA can be conducted at any level: province, zone, district, AES depending on particular needs.
AEA is usually undertaken by multi-disciplinary teams which bring to the exercise a range of different skills.
AES relies heavily on both Primary and Secondary data/information relating to bio-physical and socio-economic parameters in the system.

8. Information is gathered in AES through:
Document analysis
Workshops
Rapid Rural Appraisal (RRA)
Participatory Rural Appraisal (PRA)
