Improving the activity system $($HAS$)$ in farming and permaculture practices can bring numerous benefits to the business. By adopting a more sustainable and efficient approach, the farm can create a competitive advantage and enhance its overall performance. One significant improvement would be to incorporate regenerative farming practices. These practices focus on nurturing the soil and promoting biodiversity, rather than depleting the soil resources. By adopting regenerative farming techniques, the farm can restore the fertility of the soil, reduce the use of chemicals, and increase the production of crops. This approach not only enhances the quality of produce but also reduces the input costs and long$-$term environmental impact. Another improvement would be to adopt precision agriculture techniques. These technologies use sensors$,$ GPS and drones to monitor crop yields, soil conditions and weather patterns. By collecting and analysing data, farmers can make more informed decisions about irrigation, fertilization, and pest control, leading to higher efficiency and reduced waste. Furthermore, the farm can invest in renewable energy sources, such as solar or wind power, to reduce its carbon footprint and dependence on fossil fuels. By producing their own clean energy, the farm can not only reduce its operating costs but also differentiate itself in the market as an environmentally responsible business. Additionally, the farm can explore value$-$added products and services, such as organic food markets, farm stay experiences, or educational tours. By diversifying their offerings, the farm can increase revenue streams and attract a wider customer base. Final answer: Overall, these improvements can enhance the farm's competitive advantage by increasing efficiency, reducing costs, improving product quality and sustainability, and diversifying revenue streams. By aligning with Porter's value model, the farm can strengthen its primary and secondary activities, such as production, marketing, and customer service, to create a unique and sustainable business model.
