GRASSLAND AGRICULTURE IN CHINA—A REVIEW
《农业科学与工程前沿(英文)》 2021年 第8卷 第1期 页码 35-44
• Grassland-based livestock production systems cover large areas in China.
• China is facing degradation of rangeland and has great shortage of forage.
• Five types of mixed crop-livestock systems in China described.
• Improving crop–livestock integration requires S&T and policy supports.
Interactions between crops and livestock have been at the core of the evolution of many agricultural systems. In this paper, we review the development and characteristics of mixed crop-livestock systems, with a focus on grassland-based systems, as these cover large areas in China, and face several challenges. Following the transition from the original hunting and foraging systems to a sedentary lifestyle with integrated crop-livestock production systems some 8000 years ago, a range of different mixed systems have developed, depending on rainfall, solar radiation and temperature, culture and markets. We describe 5 main types of integrated systems, (1) livestock and rangeland, (2) livestock and grain production, (3) livestock and crop – grassland rotations, (4) livestock, crops and forest (silvo-pasture), and (5) livestock, crops and fish ponds. Next, two of these mixed systems are described in greater detail, i.e., the mountain-oasis-desert system and its modifications in arid and semi-arid regions, and the integrated crop-livestock production systems on the Loess Plateau. In general, crop-livestock interactions in integrated systems have significant positive effects on crop production, livestock production, energy use efficiency and economic profitability. We conclude that improved integration of crop-livestock production systems is one of the most important ways for achieving a more sustainable development of animal agriculture in China.

GROUNDWATER DEPLETION IN THE NORTH CHINA PLAIN: THE AGROHYDROLOGICAL PERSPECTIVE
《农业科学与工程前沿(英文)》 2021年 第8卷 第4期 页码 594-598 doi: 10.15302/J-FASE -2021407
Agricultural production in the North China Plain with rainfall of less than 500 mm·yr−1 has been steadily increasing over the past 40 years, with the groundwater levels decreasing at a rate of over 1 m·yr−1. In this paper, it is demonstrated theoretically that the water level in the aquifer can be expressed as a function of agricultural production and the sum of water added as rainfall and imported from outside the basin. Therefore, the most effective measures to halt groundwater depletion are importing water, decreasing cropping intensity and growing less thirsty crops. Irrigation improvements, mulching and agronomic measures that could increase the yield per unit area have less of an impact on solving the declining groundwater levels.
