Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 1,   Pages 57-63 doi: 10.15302/J-FASE-2017192

Abstract: Grasslands are crucial parts of the terrestrial ecosystem, with an extremely high differentiation of productivityThis study focuses on the changes in productivity and diversity and the relationship between them asProductivity was significantly improved but diversity was lost by fertilizing.N fertilization also reduced the sensitivity of diversity to productivity.Mowing also slowed down the decline in diversity as productivity increased.

THE 4C APPROACH AS A WAY TO UNDERSTAND SPECIES INTERACTIONS DETERMINING INTERCROPPING PRODUCTIVITY

Frontiers of Agricultural Science and Engineering 2021, Volume 8, Issue 3,   Pages 387-399 doi: 10.15302/J-FASE-2021414

Abstract:

Modern agriculture needs to develop transition pathways toward agroecological, resilient and sustainable farming systems. One key pathway for such agroecological intensification is the diversification of cropping systems using intercropping and notably cereal-grain legume mixtures. Such mixtures or intercrops have the potential to increase and stabilize yields and improve cereal grain protein concentration in comparison to sole crops. Species mixtures are complex and the 4C approach is both a pedagogical and scientific way to represent the combination of four joint effects of Competition, Complementarity, Cooperation, and Compensation as processes or effects occurring simultaneously and dynamically between species over the whole cropping cycle. Competition is when plants have fairly similar requirements for abiotic resources in space and time, the result of all processes that occur when one species has a greater ability to use limiting resources (e.g., nutrients, water, space, light) than others. Complementarity is when plants grown together have different requirements for abiotic resources in space, time or form. Cooperation is when the modification of the environment by one species is beneficial to the other(s). Compensation is when the failure of one species is compensated by the other(s) because they differ in their sensitivity to abiotic stress. The 4C approach allows to assess the performance of arable intercropping versus classical sole cropping through understanding the use of abiotic resources.

 

Keywords： compensation     competition     complementarity     cooperation     interspecific interactions     land equivalent ratio     light     nutrients     species mixtures     water

The effect of different agricultural management practices on irrigation efficiency, water use efficiency and green and blue water footprint

La ZHUO, Arjen Y. HOEKSTRA

Frontiers of Agricultural Science and Engineering 2017, Volume 4, Issue 2,   Pages 185-194 doi: 10.15302/J-FASE-2017149

Abstract: This paper explores the effect of varying agricultural management practices on different water efficiency indicators: irrigation efficiency (IE), crop water use efficiency (WUE), and green and blue water footprint (WF). We take winter wheat in an experimental field in Northern China as a case study and consider a dry, average and wet year. We conducted 24 modeling experiments with the AquaCrop model, for all possible combinations of four irrigation techniques, two irrigation strategies and three mulching methods. Results show that deficit irrigation most effectively improved blue water use, by increasing IE (by 5%) and reducing blue WF (by 38%), however with an average 9% yield reduction. Organic or synthetic mulching practices improved WUE (by 4% and 10%, respectively) and reduced blue WF (by 8% and 17%, respectively), with the same yield level. Drip and subsurface drip irrigation improved IE and WUE, but drip irrigation had a relatively large blue WF. Improvements in one water efficiency indicator may cause a decline in another. In particular, WUE can be improved by more irrigation at the cost of the blue WF. Furthermore, increasing IE, for instance by installing drip irrigation, does not necessarily reduce the blue WF.

Keywords： field management     irrigation efficiency     water footprint     water productivity     water use efficiency

Current Situation and Future Security of Agricultural Water Resources in North China

Huang Feng, Du Taisheng, Wang Sufen, Mei Xurong, Gong Daozhi, Chen Yuanquan, Kang Shaozhong

Strategic Study of CAE 2019, Volume 21, Issue 5,   Pages 28-37 doi: 10.15302/J-SSCAE-2019.05.024

Abstract:

North China is one of the major breadbaskets in China and is critical in ensuring food security of the nation. It sustained 18% of national total arable land, and 23% of national total grain crop output using only 6% of national total water resources. However, such impressive accomplishments were achieved at huge costs incurred in resources, environment, and ecosystem. We first presented accomplishments, current situations, and main challenges facing agriculture and water use in North China. Then, using an integrated framework in agricultural water management widely adopted by international water research communities, we reviewed the trajectory of agricultural development and its associated water withdrawal, water use efficiencies, and productivities in North China from 1998 to 2015, from which some major experiences and lessons were derived. We then tentatively proposed policy and strategy pathways to ensure food security in North China in the future.
