Currently, the world is struggling to restore the earth's condition, which is getting more and more uncertain every day due to global warming. From the ice in the north pole that is starting to melt, forest fires happening everywhere, to the erratic weather. Generally, climate change factors are divided into natural and unnatural causes. Volcanic eruption, solar activity, and changes in the earth's orbit are natural causes of climate change. Meanwhile, carbon dioxide emissions from industry and greenhouse emissions are unnatural. In addition, many climate change campaigns hold to raise awareness about the long-term effects on various aspects of life, including the agricultural sector. Agriculture is the sector that is most seriously affected by climate change.
According to the Asian Development Bank Institute paper, agricultural production would fall by around 3% with the carbon fertilization impact by the 2080s and about 16% if the carbon fertilization factor did not occur. These losses can significantly center in developing countries, which would lose 9% with carbon fertilization and 21% without, contrasting to 8% gain (with carbon fertilization) and 6% loss (without carbon fertilization) in industrialized nations.
How does climate change impact agricultural production
The impacts of climate change on agricultural production vary from region to region and depend on the crop type. Malaysia is one of the countries in Southeast Asia that has been affected by climate change and caused floods in some areas. Malaysian News said that a farmer from Kota Tinggi claimed he failed to plant 2.000 cucumbers or around 10.000kg of cucumber because of climate change, with a financial loss of about RM8.000 or US$1,909. This climate change caused heat, no rain for two weeks, and increased temperature in Malaysia. This climate change is related to the conditions faced by farmers. If the conditions are incorrect, the farmers cannot reap the harvest and causing price increases. Farmers from South Sumatra, Indonesia, also suffer from climate change. Extreme weather marked by high rainfall makes vegetable crops unable to grow correctly. Sellers confirmed the price increases hit 10 to 20 percent for vegetables in the market. Ilham, a farmer from Pemulutan, admitted that he had not done gardening for two months due to bad weather and flooding. On account of this, Indonesia is one of the developing countries that currently has developed and campaigned for "Innovative climate-smart agriculture based on adaptive cultivation technology" to deal with the impact of climate change on agriculture.
Agriculture variable rate technology (VRT)
In recent years, we can see that there has been an increase in the use of these technologies in agriculture. They provide an efficient way to manage land resources while reducing greenhouse gas emissions that cause climate change. The variable rate technology helps mitigate climate change by reducing water use, carbon emissions, and soil erosion. Farmers can use sensors and drones to collect soil moisture and temperature data. The precision agriculture software then analyzes the data, which calculates the best time for irrigation. There are two types of variable rate technology applications; map-based control and sensor control or real-time control.
Map-based control, the application rate is adjusted using a digital map, also known as a prescription map. The input concentration is modified as the applicator moves through the field, using the field position from a GPS receiver and a prescription map of the required value. Map-based control may assist farmers and agribusinesses in gathering specific information about soil type, field scouting data, topography (high and low grounds), soil color and texture, and crop yield.
Sensor control is when information obtained throughout the operation decides what rates to apply in different locations. It necessitates sensors that can detect vital data 'on-the-fly' and intends for a specific task, such as herbicide spraying.
Avirtech variable rate technology
Variable-rate technology (VRT) uses sensors and drones to measure and apply variable water rates, fertilizers, pesticides, or other agricultural chemicals to crops. This technology has been around for a while now. Still, with the emergence of new technologies like drones and AI-driven precision agriculture systems, this technology has more potential to combat climate change. And this is what Avirtech variable rate technology can combat climate change can do.
Variable rate technology - Precision spraying
Many studies link climate change with increased pest and disease attacks. In 1998 in West Java, Indonesia, a planthopper attack exploded due to increased climate change temperature. The research resulted in Korea showing an increase in insect pest attacks due to climate change. To overcome excessive pest attacks, farmers will undoubtedly do extermination with pesticides. However, the use of high doses of pesticides will lead to a reduction in soil nutrients.
Unintentionally, this degradation of soil quality affects the climate in two ways: it interferes with the growth of plants that take carbon from the atmosphere. It releases soil carbon previously stored by worms that carry leaf matter underground. The sharpness of the human senses has its limits. Therefore, farmers and agribusiness need a piece of intelligent agriculture machinery that can help analyze and apply it appropriately.
Avirtech Aviro D16 drones, M16 Drones, and E16 drones adapt the fundamental of sensor control. They have sensors that can detect pests and weeds on plants. With the actual data, farmers and agribusiness do not need to predict which crops will be sprayed with pesticides or spray pesticides on all crops. This precision agriculture with sensor control VRT can certainly keep organic carbon from the soil, and this does not damage agricultural productivity and contribute to climate change.
Variable rate technology - Precision mapping
Society suffers from the lack of availability of clean and drinkable water. Climate change makes rising sea levels cause shrinkage of potable water and agricultural land in coastal areas and crop damage due to salinity. Likewise, farmers and agribusiness negligence in determining irrigation flows also impact soil fertility and availability of clean water structure and can cause flooding during the rainy season.
To that end, Avirtech provides precision drones mapping to mitigate the scarcity of clean water caused by inappropriate agricultural systems. Our drones mapping enables farmers and agribusiness to collect water sources and do appropriate water flow mapping and flood control. Therefore, farmers and agribusiness can reduce soil excavation errors that result in soil degradation.
To conclude, the emergence of new technologies like drones and AI-driven precision agriculture systems can increase the potential to resist climate change. So do what Avirtech has the technology that can help combat climate change in various ways.
