Problem Statement and Objectives

Problem statement: The use of traditional tractors and other heavy equipment in farming can have negative environmental impacts, such as soil compaction and erosion.

Engineering solution: Develop autonomous farming equipment that uses lighter, more efficient technology to minimize environmental impacts and reduce labor costs. Tasks could include plowing, planting, harvesting of crops, spreading fertilizers and pesticides, monitoring of crop health (camera to see the color of the leaves of the plant). (We could also firstly only focus on spreading fertilizers and than also do pesticides or planting of seeds, this was what the tutor was talking about, starting small and than potentially adding functionalities as we go).

Problem statement: The demand for fresh produce within cities is increasing, but traditional agriculture practices may not be practical within urban areas.

Engineering solution: Design a vertical farming system that can be deployed in urban areas, using controlled environments and efficient lighting and climate control systems to maximize crop yields and reduce space and resource usage. (Cons, this might be expensive? And these kits seem to already exist).

Problem statement: Farmers face challenges in optimizing crop yields while minimizing water usage and labor costs.

Engineering solution: Develop a precision irrigation and fertilization system that uses sensors and real-time data analysis to deliver water and nutrients directly to crops in the right amounts.

Some problem statement examples:

The challenge of developing autonomous farming technology that is robust, reliable, and economically feasible for farmers to use. (Building cheap and reliable robotics to support farming)

1. Drone: used for crop identification, general health, infrared camera to see temperature of the soil,
2. Irrigation system:
3. Pestcide and Herbicide system:
   

Problem statement irrigation

Problems with irrigation:

-         Supplying water to all crops on a farm

-         Wastage of irrigation water during periods of rain

-         Maximizing crop yield while minimizing water usage

These problems mostly important in countries with less rain and countries which rely heavily on agriculture (i.e. India).

In countries where water shortages aren’t a problem farmers simply use a sprinkler system whenever they feel like watering crops, which uses up more water than necessary and doesn’t optimize crop growth/health.

Use of smart irrigation system: use information of moisture sensors, humidity sensors, thermometers, weather forecasts etc. monitor sprinklers and regulate them automatically based on the gathered data.

New problem: energy cost of the irrigation system. Can optimize energy cost with solar panels. This will drive up the cost of the system; do more research to find out what farmers would be willing to invest for such a system. Also do research to find how much water can be saved using this system and how much it increases crop yield.

Problem statement pesticides

Pesticides are needed to protect crops from animals, diseases, other plants. Not being able to pinpoint where the threats are results in the farm having to spray all crops with pesticides

-         Doing this is bad for the environment as well as being potentially harmful to humans applying the pesticides/eating the harvested crops.

-         Needing to spray all crops means wastage of pesticides which are expensive.

Most farmers still use the method of spraying all crops on their farms. Another method is to have better systems for detecting threats to crops earlier and only applying pesticides in affected areas. For farmers to do this manually is more time consuming and inefficient. Instead a system using a robot or drone can be used to identify i.e. diseases in plants and spray them with pesticides.

Problem statement responsible farming

The use of autonomous farming systems leads to several social, legal and ethical dilemma's. These include: responsibility challenges, animal treatment, the loss of jobs, cyber security and the threat that only big farms can keep up.

In our project we could explore these issues and suggest possible methods in which to tackle them. In order to do this an extensive literature research is needed. Also we can investigate what different stakeholders such as farmers, environmental organizations and consumers think about the developments of autonomous farming.

Possible subtopics to focus on:

milking machines

impact on rural communities (job loss, deprivation of culture)

Problem statement:

Maintaining a farm at home requires a significant amount of effort, time resources and perhaps even expertise. These elements tend to discourage people from partaking in this activity. Thus as a result, these individuals miss out on the benefits of having fresh produce, sustainable food source, food security, and other health benifits. This problem is compounded by the fact that people have busy schedules, lack expertise, or generally do not want to put effort into it. How can AI be utilized to remove these barriers and enable individuals to maintain a farm in their homes with minimal effort and time?

Solution: Vertical farming at home

Benefits: Helps reduce cost of groceries

Fresh produce with low cost

Can potentially sell to local markets, and improve local economy Improves community

Decreases depression and anxiety because it is a healthy hobby

Less pesticides

More sustainable

Problem: Limited space for vertical farming at home.

Potential solution: AI could potentially optimize space utilization. Perhaps it can be done where the layout of plans using computer data analysis. It can determine optimal placements of plants and the best plant densities based on their growth characteristics, available light, and nutrient needs.

Who are the users

Primary users:

3. Local governments: Local governments may indirectly benefit from home vertical farming systems by promoting sustainable food production practices, potentially reducing the burden on municipal waste management systems, promoting local economic development, and improving community health outcomes.

Downsides:

1. High cost: The technology used can be expensive. This could be a barrier to entry for some individuals, limiting acces to the benefits of indoor farming.
2. Energy usage: This system requires constant source of energy to power lights, climate control, and potential other equipment. This could therefore lead to a higher energy usage and energy bill.
3. Limited crop variety: The crops that can be grown are limited to the space available in the farming system. Crops with large roots, big canopies or bushes are quickly limited in space.
4. Maintenance: Home vertical farming systems require regular maintance and monitoring to ensure propwer growing conditions and prevent pests and disease. This can be time consuming and may require a specialized skill.
5. Technical challenges: This system may involve complex technical systems and equipment, which can be challenging to setup and troubleshoot for individuals without any prior technical experience.
   

What do they require

1. Lighting: Indoor plants require artificial lighting to supplement natural sunlight. LED grow lights are a popular choice for home vertical farming systems due to their energy efficiency and ability to provide the right spectrum of light for plant growth.
2. Growing medium: Plants in a vertical farming system require a growing medium to support root growth and provide access to nutrients. Common growing media include soilless mixes, such as coconut coir or perlite, or hydroponic systems, such as nutrient-rich water solutions.
3. Nutrient delivery system: Plants in a vertical farming system require a consistent source of nutrients to support growth and development. Nutrient delivery systems can vary depending on the type of growing medium and system, and may involve automated dosing systems or manual nutrient solutions.
4. Ventilation: Adequate air circulation and ventilation is important for maintaining healthy growing conditions and preventing the buildup of moisture and odors. Fans or other ventilation systems may be needed to ensure proper air flow.
5. Temperature and humidity control: Indoor environments can be prone to temperature and humidity fluctuations, which can affect plant growth and development. Home vertical farming systems may require temperature and humidity control systems, such as heaters, air conditioning units, or humidifiers.
6. Monitoring and control systems: Home vertical farming systems may include sensors or monitoring systems to track environmental conditions, such as temperature, humidity, and nutrient levels. Automated control systems can adjust lighting, nutrient delivery, and other factors as needed to optimize plant growth.
7. Structure and support: A vertical farming system requires a structure to support the growing components, such as shelving units or vertical grow towers. The structure must be sturdy and stable to support the weight of plants and equipment.

Article: http://27.109.7.66:8080/xmlui/handle/123456789/682

The article highlights the efforts being made to automate the labor-intensive agriculture industry through the use of robots and machines. A vision-based row guidance method is proposed for autonomous farming robots to navigate through row crops in a field, using machine vision to detect the offset and heading angle in real-time. The robot platform is designed with an open architecture and a control scheme for row guidance. The focus of the robot is to monitor the health of the plants by observing their leaf color and height, as well as the surrounding environmental conditions such as temperature, moisture, and humidity. The information collected is then used to determine the health of the plant, which is displayed on an LCD screen.

Article: https://link.springer.com/chapter/10.1007/978-90-481-9277-9_20#Abs1

The text discusses the demand for advances in automation in agriculture, horticulture, and forestry due to high labor costs. The focus is on the potential of robotic outdoor systems to increase efficiency and make operations economically viable. The chapter provides examples of autonomous crop protection operations that are likely to be commercially available in the near future. These operations, such as scouting and monitoring, can be automated for increased efficiency, but current systems still have drawbacks, including a lack of robust and safe behaviors. The use of high-precision targeting based on individual weed plant detections holds the potential to greatly reduce the use of resources, such as herbicides.

1.      Summarizing the lessons learned from regulation of autonomous equipment in other sectors of the economy

2.      Describing the current status of regulation related to autonomous crop equipment

3.      Providing an example from the United Kingdom of how regulation can affect the development of autonomous equipment in crop production.

The paper also argues that regulation will have a major impact on the type of autonomous crop equipment that is commercialized and the pattern of its adoption.

Aloysia:

Articles 1-5 can help justify the need for the development of vertical farming (without focusing on vertical farming itself). Articles 6-9 discuss the benefits and drawbacks of vertical farming. Articles 7-12 discusses crops / most efficient input→ output in food/farming.

The article examined the effects of organic farming on plant diversity at both local and landscape scales. They hypothesizes that the consequences of organic farming would differ depending on the scale of uptake in a particular landscape. The study utilizes a landscape scale approach and found that the local effect of organic farming was consistently stronger, with higher diversity in borders adjoining organic fields. The results showed that “forb richness” was higher in borders located in landscapes with higher proportion of organic land (potentially due to dispersal of mainly annual plant species from the organic fields). The study highlights the importance of considering multiple scales, including local and landscape factors, to better understand biodiversity patterns, and the potential benefits of organic farming.

The article explores the socio-economic link between organic and non-organic farms, and the contribution of organic farming to rural development (in England). The study found that organic farms tend to employ more people and differ in characteristics (to non-organic farms). Differences in local economic connections between the two were miniscule. The authors argue that a more nuances approach is needed when considering the rural development benefits of organic farming, where other factors such as the type of enterprises on the farm and the marketing strategies adopted by the business should also be taken into account. The focus of debate shifted from equating organic production with local supply and assuming a local economic benefit to a broader understanding of the local “agro-food” economy and the connections between different types of farms and local and export markets.

F. (2014). Climate-smart agriculture for food security. Nature Climate Change, 4(12), 1068–1072. https://doi.org/10.1038/nclimate2437

The paper discusses “Climate-smart agriculture” which is a strategy aimed at ensuring food security with regards to Climate change. Changes in rainfall and temperature patterns have been affecting agriculture. The livelihoods of those dependent on agriculture become more vulnerable, especially the poor. CSA aims to reduce these risks by increasing the adaptive capacity of farmers and improving resilience and resource use efficiency in agriculture. This would involve efforts from farmers, researchers, the private sector, civil society, and policy makers, with focus on; building evidence, increasing local institutional effectiveness, fostering policy coherence, and linking financing.

A section that I focused on discusses the impact of international trade on biodiversity and the environment. Nearly 1 billion people consume internationally traded food products, which leads to environmental impacts in the country of origin, mostly in developing countries. International trade drives 25% of bird species loss and more than half of the biodiversity impacts due to loss of suitable habitat from soybean production in the Brazilian Cerrado. Life cycle assessment (LCA) is emerging as a method for evaluating the end-to-end environmental impact of products and can link a final commodity to its associated biodiversity loss. However, it can be challenging to measure and aggregate impacts across a product's life cycle. The impact of international trade on biodiversity through climate change has not been considered, but countries could design trade policies that consider climate change and biodiversity to reduce damages. International trade also contributes to climate change through GHG emissions associated with traded commodities and their transport, which make up a small percentage of the total GHG emissions from food production. There is still a need for research to understand how international trade can be used to mitigate negative impacts or take advantage of benefits of climate change.

The article states that the world cereal (?) production increased by 2.3% in 2019(?????), but the number of people facing severe food insecurity may double to 265 million by the end of 2020 due to the COVID-19 pandemic. The problem is severe in urban areas where the global population is projected to increase, causing food supply chain disruptions and increase in food waste. To address the issue, there is a need for more resilient food systems, reduced food waste, and strengthened local food production. Home gardening and urban agriculture can play an important role in advancing food and nutritional security and improving ecosystem services, but risks of soil contamination by heavy metals must be addressed.

This paper aimed to gain insights into people's attitudes towards small scale vertical farming technology for growing food at home. A prototype was developed that incorporated sensor and LED technology and was tested in a user study. The results of the study showed that people generally had a positive attitude towards the system, although a fully autonomous system was not preferred and concerns about food safety were raised.

This paper discusses the current challenges policy makers face with regards to providing food for the growing world population (expected to be 9.7billion by 2050). The issue of declining fertile land per person due to increasing population, urbanization and climate change was discussed. The paper highlights urban vertical farming as a potential solution because it involves the use of technology and automation for “land-use optimization.” Vertical farming aims to both increase productivity and reduce the environmental impact, whilst providing benifits (clean food source, biosecurity, protection from pests, droughts, and reduced transportation - using less fuel/less emissions). The article discusses pros and cons of vertical farming.

This article discusses the economic feasibility of Vertical farming. This was done by designing and simulating a 37 floor farm. The results showed that the farm could yield 3,500 tons of fruits and vegetables, and 140 tons of tilapia fillets, which is 516 times more productive than a traditional 0.25ha farm. The estimated costs were estimated to be 200million euros. The farm itself would require 80million litres of water and 3.5GWh of power power year. The cost of the produced food was estimated to be about 3.50euros to 4euros per kg. The article also states that more research is needed to optimize the production process to reap the full economic, environmental, and social benefits.

This paper discusses the growing need for vertical farming caused by food security concerns, urban population growth, limited farmland, and “food miles” (how far the food travels from farm to plate). The paper suggests that urban agriculture is a solution to these problems. Vertical farms combines food production and consumption in one place, and is stated to be suitable and an efficient option for urban areas where land is limited (and/or expensive). Advances in greenhouse technologies such as hydroponics, aeroponics, and aquaponics have made vertical farming more promising. Like the other papers mentioned prior to this one, this paper acknowledges obstacles with implementing vertical farms such as; economic feasibility, regulations, and lack of expertise.

They could reliably identify crops in a field with a variety of plants as well as diseases on plants, classified by small details like spots on leaves.

Sri, M.S., Nikita, V.M., Bhargavi, S.D., Muneeruddin, M., Pragthi, K., & Kranthi, T. (2021). APP BASED AUTOMATIC IRRIGATION SYSTEM.

The article describes a simple water management system for farms using WiFi. Using data from soil measurers underneath the ground were crops are, more water can either manually or automatically be irrigated to the specific areas, depending on the users preference. The automatic model compares the current moisture levels with standard expected values and either switches the water on or off withing acceptable ranges.

This article considers an expanded and more sophisticated system for automatic irrigation compared to the previous article. Using a solar powered system which besides moisture levels also considers weather forecasts and soil temperatures, It can optimize water usage for crops on a farm, while not requiring any energy other than that generated by its solar panels. This means it is a valuable tool on farms without easy access to energy.

This article investigates the use of robots in the harvesting of crops. It has two main objectives: reviewing the state-of-the-art technology in automatic harvesting and formulating challenges for future research in the field. The performance of the harvesting robots are determined by various factors such as localization, speed, successful harvesting and probability of damage. It was found that the fruits were harvested successfully 66% of the time. The main challenge is dealing with the dynamic environment of a crop farm. Future research should be focused on this aspect.

To do this, the optimal trade-off between food production and energy consumption needs to be found. A hierarchical system is used in the model. This means that the components of the systems are linked to each other in a hierarchical manner from top to bottom. The proposed model should be able to deal with fast changing weather conditions and the slow food growing process simultaneously.

This paper analyses the role of AI in farming. It sees AI technologies as a way to improve food production and ensure that the growing world population can be fed. There are various technologies that are useful in an agricultural context such as disease detection, checking the ripeness of crops, field management and automatic irrigation. This should make farming both more profitable and sustainable in foreseeable future.

An AI models for detecting diseases in banana crops are designed and tested. The AI use (dcnn) deep convolutional neural networks and are trained with transfer learning. Transfer learning is a method to train AI in which the program is shown many pictures of a certain phenomenon, in this case crop diseases. Afterwards it should be able to detect new pictures of the same theme. The best AI were able to detect diseases in banana crop more than 90% of the time.

Wan-Soo Kim, Dae-Hyun Lee, Yong-Joo Kim, Taehyeong Kim, Rok-Yeun Hwang, Hyo-Jai Lee, Path detection for autonomous traveling in orchards using patch-based CNN, https://www.sciencedirect.com/science/article/pii/S0168169920301460?casa_token=BwbBLKZ8TM0AAAAA:1jAKheg64XZ_z5pxpEC1h2AtTO9SAmJpv9Dcfrr8zTqB8gMNM7kfBAcgTmA6CGWYgGUrRXUylg

This paper proposes a novel and efficient patch-based approach for autonomous path detection in semi-structured environments such as orchards. The focus was on a perspective path-detection approach that uses CNN-based image-patch classification. The proposed path-detection approach can segment the path area by partial area classification, and can be implemented with a shallow CNN model trained with small datasets, in contrast to segmentation learning with pixel-based classification.

This paper discusses an approach that will lead to the development of future Precision Autonomous Farming Systems. A farming system has a number of sub-systems that operate at a lower level. Most of the time only minor changes take place to the boundaries of the farm although major restructuring can still take place within the allocated land. Thus, the emphasis is on the restructuring of the existing farms so that they become amenable to autonomous farming.
This paper presents the requirements of a future autonomous farming system. It emphasized the need to introduce a strict structure and the importance of taking into considerations the farm system parameters in developing an a priori PFDS that is continuously used by each precision autonomous farming unit. The PFDS is primarily used for machinery navigation and seeding.

All kinds of agricultural robots have been researched and developed to implement a number of agricultural products in many countries. This Agribot can performs basic elementary functions like harvesting, planting and spray the pesticides. The application of agricultural machinery in precision agriculture has experienced an increase in investment and research due to the use of robotics applications in the machinery design and task executions. Multipurpose autonomous agricultural robot has successfully implemented and tested for various functions like ploughing, seeding, leveling and water spraying. The advantages of multipurpose agricultural robots are reducing human intervention, ensuring proper irrigation and efficient utilization of resources. The proposed system is mainly used for crop establishment, plant care and selective harvesting.

This paper review three important developments that guide researchers for the future development of autonomous robotic in agriculture. The first important development is navigation, which includes the uses of GPS technology and vision-based navigation to guide the robot through the agricultural fields. The second is the development of harvesting systems on the robot that describes sensors uses for harvesting, and actuators to control harvesting devices. The third development is a soil analysis system that gives farmer information about the condition of the land.
