Why an Orchestration Platform is Critical for Agriculture
Traditionally, satellites, drones, and on-ground sensors have been used independently to gather data on crop health and yield. While each technology offers unique insights, their true potential is realized when they work in unison. Here’s why:
- Improved Data Accuracy: Ground sensors can provide real-time data on soil moisture and crop health, which complements satellite images and drone visuals.
- Better Crop Predictions: Regular data updates from various sources help create a dynamic and accurate model for crop yield prediction and classification.
- Cost Efficiency: Consolidating data collection can reduce the need for repeated manual field visits and provide a scalable solution for farmers.
This synergy forms the basis of the orchestration platform that brings together data from various sources to create a holistic view of crop health and development.
Challenges in Indian Agriculture and the Role of Technology
Despite being a major employer, agriculture in India only contributes 17.4% to the country’s Gross Value Added (GVA). The sector is plagued with issues like high volatility of input prices, lack of access to technology, and inefficient post-harvest supply chains. Many of these challenges can be addressed through precision farming and data-driven decision-making. Some key areas of concern include:
- High Input Costs and Poor Accessibility: Most farmers rely on traditional farming methods, leading to the overuse or underuse of fertilizers and pesticides.
- Suboptimal Cropping Patterns: Farmers often make planting decisions based on historical data rather than current market demand, leading to overproduction and poor pricing.
- Lack of Financial Inclusion: Only 30% of farmers have access to institutional credit, making it difficult to invest in new technology.
By leveraging remote sensing data and automating data collection and analysis, farmers can get real-time crop advisory, thereby improving crop health, yield, and market readiness.
Remote Sensing Technologies and Their Application in Agriculture
Remote sensing has become a cornerstone for agriculture innovation, offering multiple ways to monitor crop health and predict yields. Here’s how it’s making a difference:
- Satellite Imagery: Satellites provide a bird’s-eye view of large geographical areas, making it possible to assess crop conditions and forecast yields without the need for on-ground presence. Projects like “FASAL” in India utilize satellite data for monsoon statistics and crop cycle monitoring.
- Drones and UAVs: Drones equipped with multispectral and hyperspectral sensors offer a closer look at crop health, detecting issues like pest infestations or nutrient deficiencies.
- On-Ground Sensors: These sensors capture real-time data on soil moisture, temperature, and other factors. When integrated with satellite and drone data, they provide a comprehensive picture of the crop’s health.
Key Indices for Monitoring Crop Health
Remote sensing relies on several indices to measure and analyze crop health and growth. Here are a few important ones:
- Normalized Difference Vegetation Index (NDVI): Measures chlorophyll content to assess vegetation health and identify areas of stress.
- Land Surface Wetness Index (LSWI): Quantifies moisture levels in soil and plants, which is crucial for detecting drought stress.
- Radar Backscatter: Uses synthetic aperture radar (SAR) to evaluate soil and vegetation moisture.
- Fraction of Active Photosynthetic Radiation (FAPAR): Measures the density of plant biomass and CO2 levels, giving insights into photosynthetic activity.
These indices help create a digital crop signature that can predict yield, detect diseases, and optimize input usage.
Need for an Orchestration Platform: What it Involves
The orchestration platform is designed to automate the coordination between different data sources—satellites, drones, and sensors. Here’s how it works:
- Data Aggregation: Collects data from multiple sensors and platforms and consolidates it into a unified framework.
- Continuous Ground-Truthing: Real-time updates ensure that models are trained with the most recent data, enhancing the accuracy of predictions.
- Scalability: A nationwide network of sensors and drones can provide continuous, real-time data to scale precision farming solutions effectively.
Actionable Tips for Implementing an Orchestration Platform
- Start Small: Implement orchestration on a smaller scale by integrating just two or three data sources, like ground sensors and satellite data.
- Focus on High-Impact Areas: Identify key regions or crops where technology can provide immediate benefits, such as high-value crops like rice or wheat.
- Invest in Training and Support: Educate farmers and agri-businesses on how to use the data effectively for decision-making.

The paper proposes a three-tier architecture to facilitate the use of remote sensing data in the agriculture sector, focusing on improving data accessibility, processing, and application through an orchestration platform. The architecture is divided into the following layers:
1. Physical Layer
The physical layer consists of various data collection sources, including on-ground sensors, drones, CCTV cameras, and satellite data from open-source remote sensing systems. This layer provides the fundamental raw data needed for agricultural monitoring and analysis. To handle the large volume of data, such as Terabytes (TBs) of satellite and drone imagery, the data should be published on cloud platforms for efficient storage and access.
2. Data Processing Layer
The data processing layer comprises several pipelines designed to process various types of data:
- Satellite Data: Preprocessing returns spectral data and indices such as NDVI, EVI, and IDBI.
- IoT Platforms: Ingest and process data from sensors, such as soil moisture sensors.
- Drones and CCTV Cameras: Capture images that are later annotated and processed using a human-in-the-loop machine learning model for quality assurance. This layer can expose the processed data through a restful API to allow for integration and data retrieval from a central repository.
3. Orchestration Layer
The orchestration layer integrates and provides access to annotated imagery and analytics-ready data. It also envisions the creation of a marketplace for agriculture databases, AI/ML models, and other data solutions. The Agri API and GIS layers allow external users to interact with the data using standard OGC services like Web Map Service (WMS) and Web Map Tile Service (WMTS).
4. Innovation Ecosystem Layer
This layer fosters collaboration among industries, researchers, and academicians by providing a digital backbone, the Unified Agri API. This backbone supports the development of farmer-centric applications and use cases based on ground-truth data and AI/ML models.
Case Study: Paddy Crop Insurance Using a Satellite-Based Composite Index of Crop Performance
The case study focuses on a paddy crop insurance scheme in West Bengal, India, using a satellite-based composite index to estimate crop yield and losses. The key aspects include:
- Motivation: The Pradhan Mantri Fasal Bima Yojana (PMFBY) provides yield-based insurance for farmers. However, the traditional methods of yield estimation are manual, error-prone, and insufficient for accurate insurance claims.
- Problem Statement: Developing a mathematical model for yield prediction is challenging due to the dynamic features like weather conditions, soil quality, and post-harvest management. Data-driven machine learning models can help address this, but variability and lack of reliable datasets pose significant challenges.
- Study Area: The study is conducted in West Bengal, where agriculture is a primary occupation. The collected field data from multiple Insurance Units (IUs) provided ground truth data for developing the model.
- Results and Analysis: The proposed method, the Bangla Shasya Bima Scheme, showed promising results in yield prediction using satellite indices, reducing dependency on manual processes and ensuring objective insurance claim settlements.
Conclusion
The paper concludes that while remote sensing data is valuable for digital agriculture, it is currently underutilized due to data unavailability and fragmented innovation in the AgriTech space. The proposed orchestration platform could democratize access to remote sensing data, enable collaboration, and create opportunities for innovative solutions.
This platform could significantly improve yield estimation models and insurance processes by providing continuous ground truth data and leveraging cloud-based APIs. By integrating remote sensing data with AI/ML models, it can help farmers and insurers make more informed decisions, resulting in better outcomes for all stakeholders.
