How Remote Sensing Helps Smallholder Farmers for Sustainable Crop Management

Remote sensing plays a crucial role in assisting smallholder farmers with sustainable crop management. By utilizing satellite imagery and other remote sensing technologies, small-scale farmers can access valuable information about their crops and fields, enabling them to make informed decisions that enhance productivity and sustainability. Read on to learn more!

Remote sensing technology carries a significant potential for reshaping how we approach agriculture. This technology can strengthen decision-making processes determining agricultural productivity, yield forecasting, and regional to national food supply chain. Despite small agricultural areas, diverse geographic factors, and assorted cropping, gaining access to remote sensing data has become increasingly straightforward, thanks to satellites and drones. The data frequency has escalated, and the cost has significantly dropped.

This technological marvel is crucial in assisting small farmers in managing their crops sustainably. By offering vital crop insights, remote sensing guides farmers to make informed decisions and refine their agricultural strategies.

Here are some ways remote sensing aids smallholder farmers in sustainable crop management:

Crop Protection: A fundamental pillar of sustainable farming, this technology aids in decreasing crop losses stemming from pests, diseases, weeds, and more. Remote sensing offers early detection and promotes concentrated intervention.

Crop Monitoring: Remote sensing permits farmers to observe expansive crop areas, noting changes in vegetation health and growth. Detailed and current data regarding crop conditions pave the way for proactive measures and enhance crop production.

Irrigation Management:  Efficient water management is fundamental for agriculture and sustainability. Remote sensing tools offer vital data about soil moisture levels and crop water necessities. This guides farmers in efficiently managing irrigation, therefore conserving water resources.

Crop Disease & Pest Monitoring: Remote sensing facilitates early detection of crop diseases and pests. A thorough analysis of spectral signatures can unveil potential disease outbreaks. This targeted strategy reduces pesticide use, overall costs, and environmental harm.

Yield Estimation and Forecasting: Remote sensing data can estimate crop yields and predict harvest outcomes by analyzing historic yield data and NDVI values. Farmers can assess crop performance, anticipate yield levels, and plan logistics by analyzing vegetation indices and historical data. Accurate yield forecasting enables better market planning, reduces post-harvest losses, and improves profitability for smallholder farmers.

  • For Land Cover and Land Use Mapping: Remote sensing assists in monitoring land cover and use alterations. This supports land management and planning initiatives.
  • During Environmental Monitoring: Remote sensing aids in analyzing environmental parameters. It assists in studying the impacts of human activities and natural phenomena on ecosystems.
  • In Natural Hazard Assessment and Management: Remote sensing assists in monitoring and managing natural hazards. This supports disaster management efforts.
  • For Urban Planning and Development: Remote sensing offers crucial information on urban dynamics. This aids in planning for sustainable urban development.
  • In Geospatial Analysis and Modelling: Remote sensing data supports spatial analysis and modeling. This simplifies decision-making across various disciplines.
  • In Climate Change Studies: Remote sensing assists in climate change research. It provides data on parameters such as sea surface temperature, ice cover, and atmospheric conditions.

Presenting KhetiBuddy, your partner for guiding and monitoring crops of smallholder farmers.. 

For an organization managing and engaging with a smallholder farmer network, it is crucial to guide them on agricultural practices. Connecting with them regularly is a challenge, considering scattered locations and geography. That’s where KhetiBuddy’s digital solutions bridges the gap by connecting organizations with their farmer network and remotely monitoring their crops to provide valuable insights. If you are seeking a way to make improved farming decisions, allow us to introduce our Geographic Information Systems (GIS) to your farming practices – a technology that helps you visualize data and analyze spatial information to improve and optimize farming processes. GIS allows you to track the health of individual crops, estimate yields, and react to changing conditions. 

It has the capacity to create algorithms based on these statistics for assessing the effects on farms and making the appropriate adjustments to farming activities. This includes variables such as 

  • Crop-based indices
  • Soil-based indices
  • Soil type 
  • Wind direction
  • Rainfall amounts
  • Risk mitigation for drought, erosion, and flood, and many more.

The best solution for all of your woes is KhetiBuddy’s GIS, which analyzes information on crop indicators, soil types, wind directions, rainfall, and more. The result is multi-layered, farm-focused spatial data that helps maximize crop output.

So, do you want to boost the food production of your farmer networks? If so, KhetiBuddy’s GIS-based agronomy solutions will help you improve your farming game. This technology can assist you in geotagging farms and recommending activities to optimize farms to maintain crops and soil health. Using KhetiBuddy’s GIS data, you can develop more effective and efficient farming strategies.

Here is a case study on how KhetiBuddy’s remote sensing solution helped a smallholder farmer from the state of Maharashtra, India, to prevent crop loss by monitoring crops remotely..

Case Study: Preventing Crop Loss via Crop Monitoring System

Agriculture applications for plant protection rely heavily on the timely monitoring of crop disease development. Khetibuddy’s Vegetation Indices (VIs) such as NDVI based on remote sensing are good markers of crop disease severity. Remote sensing is a quick, non-invasive, and effective approach for acquiring and analyzing Earth surface spectral properties from various sources, including satellites and ground-based platforms. Stated below is one such case study where the application fetched positive results for a farmer.

Problem area Disease infestation observed on leaves 
KhetiBuddy’s evaluation key diagnosis  Based on NDVI calculated from imagery from satellites generated by KhetiBuddy, low-crop health areas were discovered on a specific portion of the plot. It was caused by a blight infection seen in photos shared by the farmer via our crop advisory module.
Solution provided by KhetiBuddy Through its advisory platform, KhetiBuddy suggested using foliar sprays of the fungicide Copper Oxychloride and nutrients like Magnesium Sulphate.
Result  Application of suggested products at the appropriate time helped to prevent the spread of disease, saving an estimated INR 1000 in costs.
