Coastal saline cropland ecosystems are becoming increasingly vital for food security in China, driven by the decline in arable land and the growing demand for resource-intensive diets. Although developing and utilizing saline land can boost productivity, it also impacts greenhouse gas (GHG) emissions. This study uses the Yellow River Delta as a cas...
CONTEXT
As the largest emerging economy globally, China is facing crop-livestock disconnection, which causes unnecessary synthetic fertiliser use, local food and feed unsatisfied demand, and manure nitrogen (N) surplus.
OBJECTIVE
We investigated how crop-livestock regional integration combined with inter-regional transportation of food, feed, and...
Due to the rising incomes and rapid urbanization, China is facing a challenge in producing more meat while avoiding excess manure. These objectives might be in contrast: if excess manure is avoided, meat self-sufficiency might not be met, and meeting meat self-sufficiency might cause severe excess manure. Our study (i) characterizes the eastern reg...
The dominant specialised cropping system (SCS) has supported the increasing population in China, although this agricultural production paradigm could lead to environmental problems. The modern integrated crop-livestock system (ICLS) in China, designed as a recycling paradigm, can alleviate the negative environmental impacts of SCS. However, it must...
With the rapid development of circular agriculture in China, balancing agricultural income and environmental impact by adjusting the structure and scale of circular agriculture is becoming increasingly important. Agriculture is a major source of greenhouse gas and income earned from agriculture drives sustainable agricultural development. This pape...
Achieving food and feed self-sufficiency is important for both China and the world. While China's food self-sufficiency has been examined at the national and provincial levels, few studies consider lower administrative levels or different food and feed items. This study quantifies self-sufficiency in the eastern regions of China and examines correl...
The temperate desert in arid central Asia (ACA) is located along the Silk Road, an ancient land route used for economic and cultural exchange between the East and the West. In this paper, we survey of 145 surface pollen samples and related modern vegetation sample plots along an east-west desert transect in the eastern ACA in order to relate surfac...
Leaf area index (LAI) is a key biophysical parameter for monitoring crop growth status, predicting crop yield, and quantifying crop variability in agronomic applications. Mapping the LAI at the field scale using multispectral cameras onboard unmanned aerial vehicles (UAVs) is a promising precision-agriculture application with specific requirements:...
The intensification and industrialization of agricultural production leads to more and more serious separation of crop and livestock, which causes serious contradiction between livestock excrement and environment, and major challenges for agricultural sustainable development. Here, we quantitatively investigated the spatial pattern and evolutionary...
Aims
Extreme climate events have become more severe and frequent with global change in recent years. The Chinese temperate steppes are an important component of the Eurasian steppes and highly sensitive and vulnerable to climatic change. As a result, the occurrence of extreme climate events must have strong impacts on the temperate steppes. Therefo...
Fast and accurate prediction of crop yield at field scale is an effective way to optimize agricultural management by government or local farmers for improving agriculture production. Compared with satellite remote sensing, unmanned aerial vehicle (UAV) remote sensing monitoring system has some advantages, such as obtaining images at high spatial re...
Based on daily temperature and precipitation for 71 stations in three provinces in northeast China from 1961 to 2013, extreme weather events were assessed using eight climatic indices defined by STARDEX. We found that trends in seasonal and annual high temperature threshold, low temperature threshold and the longest heatwave date fluctuated upwards...
