How can we successfully integrate bees into commercial urban farms
Project IntroductionThis project will aim to solve the issue of pollination faced by commercial urban farms by using sensors to integrate bees into these farm. This project will aim to solve the issue of pollination faced by commercial urban farms by using sensors to successfully integrate bees into these farms by optimising pollination rates and tracking the health of bees automatically
IntroductionCommercial urban farming has evolved significantly since its inception. At the moment, one can observe the many different technologies being used in such farms, especially in more advanced farms viz vertical farms (WIRED, 2018). Multifarious sensors, such as temperature and humidity sensors, are able to monitor the crops’ surrounding environment and is able to enforce the most suitable parameters for the environment to achieve optimal crop growth (SIAA, 2022). Other sensors such as cameras may also be used to monitor the crops’ growth (Hwang, Lee, Kim, Baik, & Choi, 2022). Advanced artificial intelligence may also be used in some farms, whose use cases include ensuring the quality of eggs for instance (IBM, 2019). This ubiquitous integration as well as advancement of technology into many commercial urban farms indicates a diminishing room for simple improvements to be made with respect to the technological aspects of urban farming.
However, there is an area in commercial urban farming which we believe to still be in its infancy stages: growing crops that require pollination. Given that many commercial urban farms are a closed system, there are no natural pollinators – bees, butterflies, and birds – to provide pollination to crops that need it. Some farms use may pollinate the crops using inefficient methods, mainly manual pollination (ICL, 2022). As such, we are proposing a system of integrating bees, a natural pollinator, to increase the efficiency of pollination in commercial urban farms. If the project is done successfully, crops that heavily rely on pollination may be feasible for commercial urban farms, increasing the variety of crops that these farms can produce. The bees may also serve a secondary purpose of producing honey which may be commercialized.
To achieve successful integration of bees, we have identified 2 key areas that need to be fully satisfied:
· High Crop Yield
· Automation
High Crop Yield:Over-visitations by bees as well as under-visitations may result in a decrease in crop yield (Agustin et al., 2014; Game & Wildlife Conservation Trust, n.d.). Under-visitions may also result in deformed crops (University Of Maryland, 2022). Therefore, it will be important to manipulate bees' movement to achieve an optimal number of visitations for the crops.
Solution:We have designed a checkpoint system which will count the number of bees that have entered a section of the farm for pollination. If there are too many bees in that section causing over-pollination, an almond scent will be diffused to usher away the bees from there. Alternatively, if there are too few bees in another section, a lemon scent will be diffused to attract the bees (Westreich, 2020). Two light sensors and light-emitting diodes(LED) enclosed in an opaque case will be used to count the number of bees as well as the direction of the movements.
Automation:The health of the bees should be monitored automatically such that manual inspection should be done at a minimal rate. A beehive has 2 main environmental factors: Humidity and temperature. The relative humidity of a beehive may range from 50% to 95%, depending on the location of the beehive (Doull, 1976). Conversely, the optimal temperature for the beehive ranges from 34.5 degrees Celcius to 35.5 degrees Celcius (Embry, 2021).
Solution:An environment sensor will be used to detect temperature and humidity. The optimal range set for the sensors is 34.5 degrees Celcius to 35.5 degrees Celcius for temperature and 50% to 60% for humidity. A lower humidity range is selected for testing purposes as well as the fact that humidity tends to be higher around bee eggs and lower elsewhere in the hive. The health indication of the bees will be indicated using an LED in another location such that the health of the bees can be gauged remotely without going to the sensor. The data from the sensor will be transferred to the LED using M5Stack’s EzData module.
Prototype for "High Crop Yield":Figure 1 shows the setup to track bees' movement. The servo motor in this setup acts as a scent dispenser. It will activate once too many bees is determined to be going into the farm.
Figure 2 will be the area where the bees move. 2 red LEDs are used, corresponding with 2 other light sensors. They are enclosed in an opaque casing to ensure no outside light interferes with the light sensors. They are used to determine the direction of the bee's movement. Figure 3 below shows an animation of the light sensors and LED working together to track the movement of bees in and out of a farming section
In the prototype, the enclosure can fit many bees. However, for actual production, the enclosure will only be one bee length as this configuration is only able to track the direction of one bee at a time.
This functionality will be used to manipulate the number of bees going to each farm section. Figure 4 shows how the bees integrated will look from a high level. The beehive is linked to different farming sections. The setup tracking bee movements will be placed in the link. With the tracking and scent dispenser, the bees' movements are able to be manipulated to go to the sections that require pollination and away from the sections that are over-visited.
Figure 5 shows the setup to monitor the health of the bees. It uses an environment sensor to measure the humidity and temperature of the beehive. It will then transmit this data wirelessly. Figure 6 shows the setup that receives the aforementioned data. It will show the health of the bees using colours on the RGB unit -- Green is healthy, yellow is a warning, and red is dangerous -- as well as on its LCD display. This will allow for remote monitoring of bees.
