“…The increase in agricultural product prices may also cause an increase in inputs of materials such as fertilisers and pesticides for farmers. In the current context of steadily increasing agricultural product prices, China’s agricultural policy orientation has shifted from increasing production to focusing on greenness and quality, and reduction in fertiliser use is an inevitable requirement for green, healthy, and sustainable agricultural development [ 43 ]. Consequently, there is a need to both clarify the relationship between the prices of agricultural products and fertiliser use and guide farmers to reduce their use of fertiliser on the basis of ensuring stable growth of farmers’ incomes.…”

Excessive use of pesticides and fertilisers has been a key issue limiting sustainable agricultural development. China is a typical pesticide- and chemical-fertiliser-dependent agricultural production area. We have matched the target indicators related to sustainable agricultural development (SDG1 and SDG2) and analysed the gap between China and four developed countries in terms of fertiliser and pesticide use intensity and efficiency from 2002 to 2016. We have used an improved Logarithmic Mean Divisia Index model and cluster analysis to identify the factors and effects driving increased pesticide and fertiliser inputs in China, and we discuss the exploratory effects of different provinces in reducing pesticide and fertiliser application and increasing efficiency. The findings reveal that (1) China is a typical pesticide- and fertiliser-dependent agricultural production area. The average combined fertiliser application efficiency in China from 2002 to 2016 was only 28% of that of the Netherlands, and the country’s average combined pesticide application efficiency was only 35% of that of the USA. (2) The most important of the three main drivers of the increase in pesticide and fertiliser inputs in China is the value added of the primary industry, contributing 56% for the period 2007–2016. (3) Further analysis at the provincial level according to four types—high-intensity high-yield type, high-intensity low-yield type, low-intensity high-yield type, and low-intensity low-yield type—clarified the provinces that should be focused on at the national level in terms of pesticide and fertiliser application reduction and efficiency increase in the future.

Farm tractors in cultivation consume a big amount of fossil fuels and emit greenhouse gases to the atmosphere. Improving traction performance and power transfer indices of wheeled tractors and field terrain soil with higher traction (pull ability) at optimal travel reduction (TR) can optimize energy utilization. This study compares the traction performance, fuel consumption, and field productivity, of a farm tractor equipped with a new drive wheel “rigid lugged wheel (RLW)” and conventional tire wheel (CTW) in field tillage operations. Tractor with RLW resulted 24.6 kN drawbar pull and 6.6 km.h−1 travel speed at 80% tractive efficiency and 15.6% TR. While with CTW, the drawbar pull and the travel speed were 23.2 kN and 6.0 km h−1 respectively at 68% tractive efficiency and 36.3% TR. The RLW resulted in improved traction performance with similar equipment weight. Tractor with RLW also resulted 220.5% lower TR, 14.8% higher field productivity, and 15.4% lower fuel consumption. RLW can control equipment weight and field traffic intensity with the improved traction performance of wheeled tractors and will make the field operations more energy-efficient and economical. For enhanced field drivability of RLW, further work is required to test for diverse field conditions and differently sized tractors.

“…The achievement of these goals requires the planning and implementation of sustainable and ecological agriculture that needs to be adapted to local conditions, the planting of crops with different adaptability on land with different resource endowments and growing conditions to promote the biodiversity of crops and livestock, an increase in the diversity and characteristics of agricultural products, and the support of sustainable agricultural production (Lee et al, 2015;Fagerholm et al, 2016;Burchfield and Poterie, 2018). This is preferential over marketoriented large-scale industrial agricultural production, which usually leads to a simplification of agricultural production structure, accelerates the loss of agro-biodiversity (Šálek et al, 2018), reduces nutritional levels due to the risk of pests, disease invasion, and environmental pollution (Li et al, 2020), and ultimately threatens human health (Liu et al, 2020). Ecological agriculture requires a deep and comprehensive understanding of regional characteristics, the positioning of agricultural development, land use, and the dual impacts of land fragmentation discussed above.…”

Agricultural land fragmentation has an important impact on ecosystem services, especially food production. However, the relationship between land fragmentation and production diversification remains controversial and requires further analysis. This study characterized the dynamics of land fragmentation and production diversification in Zhejiang Province, China, from 1995 to 2015 using remote sensing, landscape metrics, and a diversification assessment approach. The results showed that Zhejiang Province experienced increasing fragmentation of agricultural landscapes and profound diversification of agricultural production. Fragmentation had a significant negative effect on grain crop production, but it had a significant positive effect on production diversification. These findings showed that fragmentation is an important driver of the diversification of agriculture and contributes to increased dietary diversity in local households. Therefore, we believe that when addressing land fragmentation issues, both the positive and negative impacts of fragmentation in different local conditions and circumstances should be taken into account. Our findings will provide scientific support for land consolidation management and agricultural land resource protection.
