The Role of GIS in Current Food Security

Abhijeet Modi/ August 25, 2021/ Blog

The food security committees are formed across different states in order to ensure that everyone gets access to sufficient, nutritious, and high-quality food at all times. The job of these committees goes beyond ensuring safe and sufficient food for everyone. The main goal is to ensure that the dietary needs of people are met through regular access to food.

The question is what’s the role of the GIS in the current food security? How exactly does it affect the quality and production of crops on the farm? GIS (Geographic Information System) is defined as the set of automated and innovative tools that are designed to generate maps, featuring detailed layers of information about the crop quality and production across the agricultural land.

The Factors Affecting Food Quality

The first step to using GIS technology in the agricultural industry is identifying the type of information required. When it comes to food security, the farmers need to get a detailed map of the particular region. This map must clearly show the vegetation, weather, and regional boundaries. Later, information about the soil type, methods of cultivation, irrigation system, and transport routes are included. The map gives accurate information about the areas prone to risks. The main factors that might affect food security are:

  1. The food availability in the particular environment
  2. Climatic changes in the given areas
  3. The methods followed for farming and agriculture in the given lands

The most common reasons that lead to low productivity are poor weather conditions, lack of proper food supplies, and ineffective policy decisions. The major purpose of the GIS mapping is to add as many layers of information as possible to give policymakers a clear picture of the interrelationship of these factors. In other words, GIS helps people know how these factors are connected and the impact they have on the quality and security of food. The technology has proven to be effective in showing the relationship between weather conditions and crop factors. This data works as an early warning, which further enables policymakers to make accurate decisions.

GIS Mapping in Agriculture

The precise GIS mapping needs a considerable amount of data, which might be hard to obtain especially in developing countries. The lack of information could lead to inaccuracy in the information, which may affect the decisions and quality of the crops significantly. That’s why farmers are now more focused on using techniques to collect as much data about the land as possible. The goal is to generate precise information about crop quality and get a precise estimate of production easily. Another thing that GIS makes easier is the monitoring of climate in the given area. This reveals the potential of food shortages in the area. The large-scale and complex strategies are often hard to make without the data provided by the Geographic Information System. The main goal of GIS in food security and agriculture is to improve sustainability and make the process of farming as environment-friendly as possible.
