Agriculture: Some Facts

  • Agriculture is an essential activity for human survival.
  • It provides us food, clothing, biofuel, and medicine.
  • A farm can be considered as a system of production in which there are many interactions between soil-plant-atmosphere.
  • Some of the inputs required in the system are water, fertilizers, and solar radiation.
  • Not all the inputs are renewable, such as fertilizers. This implies that scarcer the source more expensive it is.
  • Sustainability is an important issue in agriculture. To achieve a sustainable production, the production system should provide benefits for the economy, society, and environment. Wisely use of inputs in the system aids to a more sustainable agriculture.

App: Fieldprint Graph

  • The Fieldprint Graph is an app that plots a variety of sustainable indicators that summarizes a production system performance in comparison with an average production system.
  • The app was based on a pre-existent webtool called Field to Market. The idea was to adapt this tool to Brazil.
  • The sustainable indicators are: energy consumption, soil conservation, emissions, biodiversity, water use, land use, and resource consumption.
  • The app helps farmers to identify where they could prioritize investments to improve their production system.

How the App Works

  • So far, the user needs to input the indexes for each one of the sustainable indicators. The indexes calculations will be developed in the future based on raw information.
  • The graph is rendered according to the user input.
  • Higher the sustainable indexes the better. If an indicator is below the average (red dotted line), it should be given priority to be improved.

Access:

Note: even though the app uses the user inputs, there are calculations in the function built to plot the graph.
