Definition of Geospatial Techniques and Climate Change
Geospatial approaches encompass the utilization of advanced technology and instruments for the purpose of acquiring, examining, and administering geographic data. The methodologies encompass the utilization of geographic information systems (GIS), remote sensing, & global positioning systems (GPS) for the purpose of gathering and scrutinizing data pertaining to the Earth's surface. Geospatial approaches play a crucial role in comprehending the effects of climate change on global ecosystems, water resources, as well as meteorological patterns (Kocaman et al., 2019).
Climate change is a global phenomenon causing significant changes in Earth's temperature, precipitation, and weather patterns due to human activities like fossil fuel combustion, deforestation, and industrial operations. It impacts the environment, human health, and economy. Geospatial tools are crucial for studying climate change effects, monitoring and analyzing changes in land cover, vegetation, and water resources. The application of geospatial methodologies in climate change studies has led to significant progress in understanding the Earth's consequences (Lu et al., 2021).
Importance of Geospatial Techniques in Agriculture
Geospatial techniques are increasingly important in agriculture due to their ability to provide accurate data on soil conditions, weather patterns, and crop development. These techniques use satellite images, GPS, and GIS to acquire, analyze, and manage agricultural data, making them crucial in various aspects of the agricultural sector (Ge & Thomasson, 2017).
Geospatial tools are being utilized in precision agriculture to allocate resources, improve efficiency, and reduce costs. They enable farmers to monitor crops, identify pests, diseases, and nutrient deficits, and make timely decisions for planting, irrigation, and harvesting. Geospatial methods also help in identifying crop choices resilient to changing weather patterns and assessing regions susceptible to flooding or drought, playing a crucial role in climate change adaptation (Gebbers et al., 2016).
This chapter explores the importance of geospatial techniques in the agricultural sector, particularly in the context of climate change. It covers various techniques like remote sensing, GPS, GIS, and UAVs, and their applications in agriculture such as precision farming, crop modeling, soil mapping, water management, climate risk assessment, land use planning, and yield prediction. Geospatial techniques offer operational effectiveness, reduced costs, and increased crop productivity, but also present financial challenges and limited specialized knowledge. The chapter also discusses case studies and future trends in geospatial technology, offering a summary of the benefits and challenges of employing these techniques in agriculture.
Geospatial techniques are crucial in modern agriculture for optimizing farming practices, enhancing productivity, and enabling informed decision-making. This discourse presents a list of effective geospatial strategies and provides scholarly references to support their practical implementation in the agricultural sector.
