Abstract The use of a corn-earthworm coculture (CE) system is an eco-agricultural technology that has been gradually extended due to its high economic output and diverse ecological benefits for urban agriculture in China. However, the effect of CE on weed occurrence has received little attention. A five-year successive experiment (2015 to 2019) was conducted to compare weed occurrence in CE and a corn (Zea mays L.) monoculture (CM). The results show that CE significantly decreased weed diversity, the dominance index, total weed density and biomass, but increased the weed evenness index. The five-year mean number of weed species per plot was 8.4 in CE and 10.7 in CM. Compared to those in CM, the five-year mean density and biomass of total weeds in CE decreased by 59.2% and 66.6%, respectively. The effect of CE on weed occurrence was species specific. The mean density of large crabgrass [Digitaria sanguinalis (L.) Scop.], green foxtail [Setaria viridis (L.) Beauv.], goosegrass [Eleusine indica (L.) Gaertn.], and common purslane (Portulaca oleracea L.) in CE decreased by 94.5, 78.1, 75.0, and 45.8%, whereas the mean biomass decreased by 96.2, 80.8, 76.9, and 41.4%, respectively. Our study suggests that the use of CE could suppress weed occurrence and reduce herbicide inputs in agriculture.

First Time

Most previous studies aim to predict ecosystem sustainability from the perspective of a sole human or natural system and have frequently failed to achieve their desired outcome. Based on the coupled human and natural system (CHANS) and its interaction with other systems, we attempted to analyze the effectiveness of the Grain to Green Program and predict future trends in the Hexi Corridor, the hub of the ancient silk road of China. At different scales, we applied a metacoupling framework to investigate the flows, effects, and causes of the complex CHANS. Three typical inner river watersheds within the corridor at three different geographic scales (local, regional and national) were estimated and compared. The Telecoupling Geo App, additional models, and software tools were employed to evaluate the CHANS series of the focal system (Hexi Corridor, local), adjacent system (Gansu Province, regional), and distant system (China, national). The results showed that most flows can be screened and quantitatively analyzed across focal, adjacent and distant systems. The social and economic transformations in adjacent and distant systems could affect the possibility and whereabouts of labor transfer in the focal system. Moreover, the labor migration increased the implementation efficiency of the Grain to Green Program as a Payment for Ecosystem Services (PES) strategy, thereby improving its ecological benefits. For the first time, we established a metacoupled model to quantitatively evaluate aspects of ecosystem sustainability in China, providing insight to the theory and application of sustainability science.

Global Growth

The opportunities for the global growth of the bioeconomy (BE) are generated by the need to expand the food supply for an increasing world population without compromising the environment even further. Organic agriculture (OA) claims to be more environmentally friendly than conventional agriculture and capable of addressing sustainable development objectives by using green technologies, resulting in economic, social, and ecological benefits. The aim of this paper is to investigate the relation between OA and BE through a systematic literature review. We addressed the benefits of OA under perspective of the main aspects of BE. As demonstrated by previous papers assessed on this review, OA can be a means to facilitate strategies for the use of renewable resources to mitigate the emergencies arising from global warming, as claimed by the BE concept. This article introduces a necessary discussion due the lack of previous studies reporting the capacity of OA to connect with the BE. As a final contribution, we present a conceptual framework characterizing potential benefits of OA under the perspective of BE, for organic farmers and researchers to advance in sustainability and green innovation.

Reliable Source

As the effective and efficient means of resources utilization, biomass energy has become a very valuable and reliable source of alternative energy in China, especially for remote areas and countryside. First, in order to facilitate the development of biogas applications and promote the economic, social and ecological benefits from comprehensive utilization of biogas in rural areas in Urumqi (Capital of Xinjiang Uygur Autonomous Region, XUAR), the biogas potential was estimated, the biogas engineering construction and biogas comprehensive utilization were evaluated, and the existing problems of biogas development were analyzed, in this study. Second, countermeasures and recommendations were proposed in trying to resolved existing problems, based on international practical experience. And, according to local climatic situation and regional characteristics in Urumqi, ecological agriculture was proposed in this study as the development mode for the rural areas in Urumqi, based on the development of biogas technologies and international practical experience.
