Northern China is one of the most densely populated regions in the world. Agricultural activities have intensified since the 1980s to provide food security to the country. However, this intensification has likely contributed to an increasing scarcity in water resources, which may in turn be endangering food security. Based on in-situ measurements of soil moisture collected in agricultural plots...

Recent human population increase has been enabled by a massive expansion of global agricultural production. A key component of this "Green Revolution" has been application of inorganic fertilizers to produce and maintain high crop yields. However, the long-term sustainability of these practices is unclear given the eutrophying effects of fertilizer runoff as well as the reliance of fertilizer p...

If diversified farming systems (DFS) are to thrive again in the United States, policies and preferences must evolve to reward the environmental and social benefits of sustainable farming and landscape management. Compared with conventional agricultural policies, policies aiding ecological diversification are underdeveloped and fragmented. We consider several examples of obstacles to the adoptio...

A long history of household-level research has provided important local-level insights into climate adaptation strategies in the agricultural sector. It remains unclear to what extent these strategies are generalizable or vary across regions. In this study we ask about three potential key factors influencing farming households’ ability to adapt: access to weather information, household and agri...

Precision farming aims to optimize field-level management by providing information on production rate, crop needs, nutrients, pest/disease control, environmental contamination, timing of field practices, soil organic matter and irrigation. Remote sensing and GIS have made huge impacts on agricultural industry by monitoring and managing agricultural lands. Using vegetation indices have been wide...

The tradition in agriculture has been to maximize production and minimize the cost of food with little regard to impacts on the environment and the services it provides to society. As the world enters an era in which global food production is likely to double, it is critical that agricultural practices be modified to minimize environmental impacts even though many such practices are likely to i...

Environmental pollution, quality problems and economic constraints require decreasing the use of pesticides in agriculture. To do so, integrated crop protection aims at developing new strategies that take into account the effects of the agricultural practices on the epidemics development. This requires predicting the development of the epidemics under particular crop practices. This, in turn, r...

Collembolans play an important role in the formation of microstructure and maintaining the agricultural ecosystem which is enriched by plant litter decomposition. Collembolans are also host of many parasitic Protozoans, Nematodes and pathogenic bacteria. Soil organisms are subjected to a variety of edaphic factors in the soil such as soil moisture, temperature, pH, amount of organic carbon and ...

Sustainable water management often emphasizes water resource quantity, with focus on availability and use practices. However, only a subset of the available water may be usable when also considering water quality. Water quality management is examined within three broad sectors—urban, agriculture, and environmental systems—to investigate how water quality sustainability (WQS) is defined by each ...

Since the Neolithic period, humans have domesticated herbivores to have food readily at hand. The cohabitation with animals brought various advantages that drastically changed the human lifestyle but simultaneously led to the emergence of new epidemics. The majority of human pathogens known so far are zoonotic diseases and the development of both agricultural practices and human activities have...
