For example, the government can help farmers get loans more easily and help build necessary infrastructure, such as ditches, dams, water source systems, etc. At the same time, scientific research institutions should be encouraged to increase their research efforts and spread successful experiences and knowledge, especially countries like China that have mature experience. Institutions must also have corresponding supporting support, such as clarifying the right to use land and water to ensure that farmers have guaranteed land use. In addition, the promotion of the concept of green agriculture, such as less pesticides and more ecological methods to prevent insects, should also be promoted simultaneously. In this way, rice and fish can grow healthily together (Berg, 2002). 7.3 Promoting broader adoption and awareness To make rice-fish symbiosis really enter more fields, it depends not only on policies and research, but also on "letting people know about it". It can be promoted through some targeted educational activities, demonstration farmland projects, or ecological education courses, not only in rural areas, but also in small-scale models in cities and suburbs (Son et al., 2022). Farmers, government officials and consumers should know the benefits of this method. For example, how it saves money, how it protects the environment, how it helps food safety, and what good effects it has on the ecosystem. Only when people understand it will they be more willing to support it. We can also build some knowledge sharing platforms so that farmers can learn from each other's experiences and promote some successful cases. Participatory training is also important, and it is best to let farmers participate in person rather than just listen. Putting these contents into school courses or community projects can also let young people and children understand the importance of biodiversity and sustainable agriculture from an early age (Halwart and Gupta, 2004). 8 Concluding Remarks Rice-fish farming is a very useful agricultural method that has many benefits for the ecological environment. For example, it allows farmers to use less pesticides and fertilizers, and it can also make the water cleaner and the soil healthier. Because fish eat the larvae of pests, there are fewer insects and weeds in the rice fields. And the presence of fish can also increase the number of animals that feed on pests, so there are fewer pests. Farmers no longer have to rely on too many chemicals, but the rice yield in the fields can still be maintained, and sometimes even increased. At the same time, the fish yield can also bring in extra income. Rice-fish farming can also increase the variety of organisms in the rice fields, such as small fish, shrimp, and aquatic plants. This biodiversity makes the entire ecosystem more stable and the field environment more vibrant. More importantly, this practice can make agricultural production more profitable and easier to stick to in the long run, which is a win-win choice for farmers. It can be said that rice-fish farming is a "less for more" agricultural method. It embodies the concept of ecological intensiveness, that is, to maximize the output of agricultural products without damaging the environment. This system makes the use of resources more efficient, such as fertilizers, water and land can be used more reasonably. It can also increase carbon storage in the soil, reduce greenhouse gas emissions, and is also beneficial to the control of climate change. The agricultural system has also become stronger and is more likely to recover when encountering disasters or pests and diseases. Through this combination of farming and breeding, farmers can not only grow rice, but also raise fish, and one field can bring two harvests. This diversified production method reduces farmers' dependence on pesticides and fertilizers, and also increases their living income, which is helpful for food security and ecological protection. Rice-fish farming can also make agricultural landscapes more beautiful and more environmentally friendly. There is now a lot of evidence that rice-fish farming is a good way to achieve sustainable agriculture. It is not only good for the ecology, but also has real help for the economy. To make this practice more widely promoted, we need to do more research and formulate more specific and powerful policies. At the same time, we must strengthen education and training so that more people know and learn how to do it. Farmers, researchers, policy
