Agriculture is one of the oldest and most important human activities. It provides food, fiber, fuel, and other essential goods for human well-being and development. However, agriculture also faces many challenges in the 21st century, such as population growth, food security, climate change, water scarcity, environmental degradation, and social inequality. To address these challenges, agriculture needs to become more sustainable and efficient, using less resources and producing more outputs. This is where technology can play a key role, by enabling new ways of farming that are smarter, greener, and more resilient. In this article, we will explore how the digital green revolution, or the use of information and communication technologies (ICTs) in agriculture, is transforming the sector and redefining what it means to be a farmer.
Precision agriculture
One of the main applications of ICTs in agriculture is precision agriculture, which is the use of technology to measure, monitor, and manage the variability of crops and soils. Precision agriculture can help farmers optimize the use of inputs, such as seeds, fertilizers, pesticides, and water, by applying them only where and when they are needed. This can reduce costs, increase yields, and improve quality, while also minimizing the environmental impact of farming. Precision agriculture relies on various technologies, such as sensors, satellites, geographic information systems (GIS), and global positioning systems (GPS), to collect and analyze data about the field conditions, such as soil moisture, nutrient levels, pest infestation, and crop growth. Based on this data, farmers can make informed decisions and adjust their practices accordingly. For example, they can use variable rate technology (VRT) to apply different amounts of inputs to different parts of the field, or use precision irrigation to deliver water to specific plants or zones. Precision agriculture can also enable site-specific crop management (SSCM), which is the adaptation of crop varieties and management practices to the local conditions, such as soil type, climate, and market demand. Precision agriculture can increase the profitability and sustainability of farming, especially for smallholder farmers, who often lack access to information, inputs, and markets.
Smart irrigation
Another important application of ICTs in agriculture is smart irrigation, which is the use of technology to control and optimize the delivery of water to crops. Smart irrigation can help farmers save water, which is a scarce and valuable resource, especially in arid and semi-arid regions. Smart irrigation can also improve crop quality and yield, by ensuring that plants receive the right amount of water at the right time. Smart irrigation systems can use sensors, weather stations, soil moisture probes, and evapotranspiration models to measure and estimate the water needs of crops, and use valves, pumps, sprinklers, and drip lines to deliver water accordingly. Smart irrigation systems can also use wireless networks, cloud computing, and mobile applications to enable remote monitoring and control of irrigation, as well as data sharing and analysis. Smart irrigation can also be integrated with other technologies, such as precision agriculture, to achieve more precise and efficient water management. Smart irrigation can reduce water use by up to 50%, while also increasing crop productivity and quality.
Automation
A third application of ICTs in agriculture is automation, which is the use of technology to perform agricultural tasks that are usually done by humans or animals. Automation can help farmers save time and labor, reduce drudgery and risks, and enhance productivity and quality. Automation can also enable new forms of farming that are otherwise impossible or impractical, such as vertical farming and indoor farming. Automation relies on various technologies, such as robots, drones, artificial intelligence (AI), and machine learning (ML), to perform tasks such as planting, weeding, harvesting, spraying, pruning, sorting, and grading. Robots can be autonomous or semi-autonomous, and can operate on the ground, in the air, or in the water. Drones can be used for aerial imaging, mapping, scouting, and spraying. AI and ML can be used to analyze data, recognize patterns, and make decisions. Automation can also be integrated with other technologies, such as sensors, satellites, and data analytics, to enable more intelligent and adaptive farming. Automation can increase the efficiency and accuracy of farming, while also reducing the labor costs and environmental impact.

Vertical farming and indoor farming can also help farmers reduce the dependence on external inputs, such as water, fertilizers, pesticides, and energy, by using closed-loop systems, such as hydroponics, aeroponics, and aquaponics, to recycle and reuse resources. Vertical farming and indoor farming can also help farmers increase the productivity and quality of crops, by using multiple layers, artificial lighting, and vertical structures, to maximize the use of space and light. Vertical farming and indoor farming can also help farmers reduce the transportation and storage costs and losses, by growing crops closer to the consumers and markets. Vertical farming and indoor farming can also help farmers improve the food security and safety, by reducing the exposure to pests, diseases, and contaminants. Vertical farming and indoor farming can also help farmers contribute to the environmental and social sustainability, by reducing the land use, water use, greenhouse gas emissions, and urban-rural gap.
Smart animal farming
A fifth application of ICTs in agriculture is smart animal farming, which is the use of technology to monitor and manage the health and production of animals. Smart animal farming can help farmers improve the welfare and performance of animals, by providing them with optimal conditions, such as feed, water, temperature, ventilation, and lighting. Smart animal farming can also help farmers prevent and treat diseases and disorders, by using sensors, cameras, microphones, and RFID tags, to collect and analyze data about the behavior, activity, and physiology of animals, such as heart rate, body temperature, respiration, and rumination. Based on this data, farmers can make informed decisions and interventions, such as adjusting the feed, water, and medication, or alerting the veterinarian. Smart animal farming can also help farmers optimize the reproduction and genetics of animals, by using technologies such as artificial insemination, embryo transfer, and genomic selection, to enhance the fertility, quality, and diversity of animals. Smart animal farming can also help farmers increase the productivity and quality of animal products, such as meat, milk, eggs, and wool, by using technologies such as milking robots, automatic feeders, and smart scales, to measure and improve the quantity and quality of outputs. Smart animal farming can also help farmers reduce the environmental impact of animal farming, by using technologies such as biogas digesters, manure separators, and nutrient management systems, to reduce the waste and emissions of animal farming.
Data analytics
A sixth application of ICTs in agriculture is data analytics, which is the use of technology to process and interpret the large and complex data sets that are generated by various sources, such as sensors, satellites, drones, robots, cameras, weather stations, soil probes, and RFID tags. Data analytics can help farmers gain insights and knowledge from the data, by using techniques such as statistics, visualization, and machine learning, to discover patterns, trends, and correlations, and to generate predictions, recommendations, and decisions. Data analytics can help farmers improve the efficiency and effectiveness of farming, by enabling data-driven and evidence-based farming, which is the use of data to support and guide the planning, implementation, and evaluation of farming practices. Data analytics can also help farmers enhance the innovation and competitiveness of farming, by enabling data-sharing and data-integration, which is the use of data to collaborate and communicate with other stakeholders, such as researchers, extension agents, input suppliers, processors, retailers, and consumers. Data analytics can also help farmers contribute to the sustainability and resilience of farming, by enabling data-monitoring and data-adaptation, which is the use of data to track and respond to the changes and challenges in the farming environment, such as climate change, pest outbreaks, and market fluctuations.
Sustainable agriculture
A seventh application of ICTs in agriculture is sustainable agriculture, which is the use of technology to reduce the environmental impact of agriculture, while also improving the social and economic aspects of farming. Sustainable agriculture can help farmers conserve and protect the natural resources, such as land, water, biodiversity, and energy, by using technologies such as precision agriculture, smart irrigation, automation, vertical farming, indoor farming, and biogas production, to optimize the use and management of resources, and to minimize the waste and emissions of farming. Sustainable agriculture can also help farmers enhance the food security and safety, by using technologies such as sensors, data analytics, traceability systems, and blockchain, to monitor and ensure the quality and safety of food, and to prevent and control food losses and frauds. Sustainable agriculture can also help farmers improve the livelihoods and well-being of farmers and rural communities, by using technologies such as mobile phones, internet, e-commerce, and e-learning, to increase the access and availability of information, inputs, markets, and education.
