What is energy assessment of agricultural production system?

Energetic assessment of agricultural production system can embrace different forms of energy account that follow the first and, in some cases, the second law of thermodynamics. Ten approaches are identified and are presented according to the energy accounting: (i) energy, (ii) exergy, and (iii) emergy.

What is energy usage in agriculture?

Energy usage in agriculture can be divided into primary or direct energy usage (lighting, irrigation, transportation, heating/cooling) and secondary or indirect energy usage (chemical, fertilizer production). Nearly one in five people (about one billion) worldwide do not currently have access to mains electricity services .

How do we understand energy use in open field agriculture?

In fact, our review indicates that for a clearer understanding of energy use in open field agriculture considerably more data points are required for each crop and studies need to adopt more extensive methodologies that also include variance and uncertainty within and between studies.

How to measure energy security in agriculture?

Presently, there exists an absence of a precise tool for accurately measuring this consumption. Hence, this study aims to identify indicators for measuring energy security in agriculture, conducted in three phases: content analysis, indicator validation, and field investigation.

What is the role of energy in agricultural production system?

Energetic assessment of the agricultural production system. A review Energy holds a key role in farm systems. Cultivation is based on the conversion of solar energy into biomass of interest.

Where can I find data on energy use in agriculture?

A number of databases provide energy use data and related indicators on energy use in EU agriculture including Eurostat, Faostat, and the farm accountancy data network (FADN). Faostat publishes data on energy use in agriculture on a country and regional basis as well as according to energy carriers .
