China has to perform high-intensity and high-chemical input agricultural production to improve its food security, which has caused uncertainty in the development of ecological agriculture. This study utilizes bibliometrics and spatial statistical methods to examine the representative literature on ecological agriculture published in the CNKI database from 2012 to 2023. The findings reveal that keywords such as rural revitalization, modern agriculture, and ecological tourism are frequently mentioned while emerging interests include carbon neutrality, eco-circular agriculture, and industrial integration. The main clusters of keywords can be classified into specific practical research, general studies, and countermeasures orderly. The themes of ecological tourism, developing mode, and rural revitalization have attracted long-lasting concerns in research over the past decade. Spatial statistical analysis indicates that, aside from the Eastern coastal areas, most provinces in China exhibit insufficient collaboration and limited spill-over effects in research of ecological agriculture, highlighting the necessity for enhanced integration. This study also provides recommendations to address the prevailing challenges to food security through the promotion of ecological agriculture in China. [ABSTRACT FROM AUTHOR]

The paper selects 30 provincial units in China as the research objects, and the input-output method is used to calculate the indirect carbon emissions from food consumption. The results showed that: (1) The indirect carbon emissions reached 1.522 billion tons, of which 19.81% came from power and heat production and supply industry, 17.19% from agriculture, forestry, animal husbandry and fishery industry, and 15.14% from food processing industry; (2) The spatial differentiation of indirect carbon emissions from food consumption was significant, showing a "center-periphery" distribution characteristic. (3) The global and local correlation characteristics are positive. Eight provinces including Henan, Hubei, Hebei, Tianjin and Shandong belonged to the "high-high" cluster type, Qinghai, Gansu, Ningxia, Guangdong and Guangxi belonged to the "low-low" cluster type, while Liaoning, Jilin and Xinjiang were classified as the "high-low" cluster type; (4) Urbanization level was the main factors affecting the indirect carbon emissions of food consumption, followed by culture level of labor force, agricultural capital investment and agricultural production efficiency. Indirect carbon emissions could be reduced by decreasing the energy consumption level of the food industry chain, promoting the green transformation of agricultural development, and guiding residents to develop reasonable dietary habits.

Agricultural non-point source pollution of aquifer, lake, riverbank and other ecosystems is caused by chemical fertilizer, pesticide, animal manure and other organic or inorganic pollutants through surface runoff and farmland leaching in agricultural production. The non-point source pollution has the characteristics of wide distribution, concealment, randomness, hysteresis and complex formation mechanism, and thus it is difficult to study and control this type of pollution. Understanding the mechanism of agricultural non-point source pollution and comprehensively being aware of the pollution sources are of great theoretical and practical significance for future research. In this paper, the mechanism of agricultural non-point source pollution was analysed in terms of rainfall and runoff process, soil erosion process, pollutant migration and transformation, and so on. In addition, the sources and sinks of nitrogen, livestock and poultry pollutants, pesticides, plastic film and other pollution sources were discussed, and the results could be informative for the formulation of agricultural sustainable development policies.

Extensive agricultural development in China has given rise to a range of environmental issues that pose a significant hurdle to the country's "dual-carbon" goal. In order to tackle this challenge effectively, it becomes crucial to tap into the potential of green financial developments as means of reducing carbon emissions. To shed light on this matter, this study collates data from a total of 30 provinces in China from 2007 to 2019. And A two-way fixed-effects model was employed to examine the extent to which the advancement of green finance (GF) in China has effectively contributed to the decrease of carbon emissions in the agricultural sector. Furthermore, our research endeavors encompass the investigation of the specific mechanisms via which green finance has its influence on carbon emissions within the agricultural sector. The findings indicate that the implementation of green finance plays a crucial role in facilitating the reduction of carbon emissions within the agricultural sector in China. Technological advancements emerge as the primary mechanism through which green finance facilitates agricultural carbon emission reduction. Nevertheless, the impact of modernizing the regional industrial structure has been detrimental in this regard. [ABSTRACT FROM AUTHOR]

With the rapid development of agricultural industrialization, agricultural nonpoint source pollution, which occurs when synthetic chemical additives (e.g. fertilizer, pesticides, and herbicides) runoff into rivers or lakes, has become a major concern. To explore the approaches of reducing the application of chemical additives, we conducted a field experiment to test whether the integrated farming systems would alleviate the nonpoint source pollution. Specifically, we tested whether mixed-cropping or mixed-cropping plus duck co-culture (MCDC) systems with optimized rice (Oryza sativa L.) cultivars could reduce nutrients runoff or leaching from paddy field. We found that compared to the mono-cropping systems, the electrical conductance (EC), oxidation-reduction potential (ORP), the contents of dissolved oxygen (DO), nitrates (NO3-), ammonium (NH4+), total nitrogen (TN), total phosphorus (TP) and total potassium (TK) of paddy water in MCDC systems all increased during the rice-growing stages. The contents of the TN, TP, and TK of paddy water in MCDC systems were 45.35%, 52.43% and 40.47% higher than those in the mono-cropping systems, respectively. Compared to the conventional mono-cropping, the mixed-cropping systems could alleviate nonpoint source pollution by decreasing the application of synthetic chemicals to rice paddies, the rice-duck co-culture system had significantly lower additions of agro-chemicals to paddy fields, which decreased the loss/runoff/leaching rates of nitrogen, phosphorus and potassium from paddy fields into the surrounding water areas by 32.73%, 8.72% and 31.88%, respectively. Considering that the MCDC systems exerted similar/even better performances as/than the rice-duck co-culture system and the rice mixed-cropping system, we deduced that the MCDC systems could also could alleviate nonpoint source pollution to a certain extent.

Food insecurity is still a major issue in developing countries, like Indonesia, particularly in East Nusa Tenggara Province. 11 of 21 districts in this province are facing food insecurity. Therefore, efforts should be made to alleviate food insecurity in the community. One way is developing leading food commodities based on local wisdom. The aim of this study is to find a method for developing leading food commodities based on local wisdom, which can be applied in East Nusa Tenggara Province. This study uses secondary data taken and reviewed by the government. The data show that agricultural commodity cultivation the food-insecure area in East Nusa Tenggara is not specialized in certain agricultural commodities, meaning various agricultural commodities are available in various districts and they are not concentrated into a certain district. The availability of commodities is relatively spreading in various districts and is not concentrated in a certain district, although each district has particular leading commodities. Paddy can be cultivated in every food-insecure district except for the East and West Manggarai districts. It depends on the climatic conditions, temperature, humidity and the effort to procure adequate means of irrigation. Upland paddy "gogo", cassava, corn, soybeans, peanuts and sweet potatoes can be cultivated in all district by adjusting appropriate cropping patterns during rainfall, temperature, and humidity suitable for the commodities. The improvement of food security in order to overcome food insecurity in 11 of 21 districts in East Nusa Tenggara should be done by promoting local wisdom, especially by the development of agricultural cultivation based on customs and local potency. Increased focus needs to be put on local potentials regarding the development of staple foods, with the support of all parties and active participation of the community. [ABSTRACT FROM AUTHOR]
