The book aim to contribute the latest understandings of physiological, biochemical and molecular bases of the responses of major crop plants to a range of different biomass produced biochar to introduce climate resilience crop varieties which leads to enhanced crop productivity and quality under stressful conditions and also for better utilization of natural resources to ensure food security through modern breeding. Finally, this book will be a valuable resource for future plant stress related research with biochar, and can be considered as a reference book for front-line researchers working on sustaining crop production under climate change. Adverse effects of climate changes on crops has developed the situation quite critical for sustainable agriculture. Food security has become in danger due to low production of agricultural crops by resilient climate and ever increasing human population. Heat, drought, salinity, soil compaction, flooding and poor soil organic carbon induced stress in crops by climate adverse conditions are major concerns in this regard. A mechanistic understanding of the interactions between abiotic stresses response of crops is needed to identify and take advantage of acclimation traits in major crop species as a prerequisite for securing robust yield and good quality. This underpins a need for crops with inherent yield increase, yield stability against multiple abiotic stresses and improved quality. Individual stress tolerance mechanisms have been well documented so far. However, mechanisms behind plants tolerance by application of biochar and its interactions with soil and plant roots towards multiple abiotic stresses are not fully understood. In addition, there will always be some uncertainty associated with modelling the complex relationships between agricultural yields, product quality with biochar under future climate scenarios. Prediction of yield and quality stability, one of most complex agronomic traits, must integrate aspects of plant development, physiology, biochemistry and genetics. Furthermore, the GxExM interactions will complicate the model predications, thus the responses of a given genotype to a defined environment under certain management strategy need to be determined empirically and used to parameterise and refine crop models.--

International audience ; Climate change and the recent financial crisis clearly show that humans have entered the anthropocene, an unprecedented era of fast and possibly dangerous changes. Unprecedented changes call for unprecedented thinking. Indeed, agriculture research has been too long driven solely by the need for higher yields using classical agrosciences, whatever adverse ecological effects. Agricultural research needs the input of other sciences such as ecological, economic, social and political sciences. Those uncommon sciences emerge in agricultural research since few decades, but there is actually no precise trends and data on the speed of emergence of specific topics. Therefore, here we report: 1) an analysis of the emergence of topics in the journal Agronomy for Sustainable Development, and 2) a review of selected articles published in 2009. First, to analyse topic emergence we studied three data sets: most-cited articles from 1999 to 2009, topic hits in article text from 1999 to 2009, and most downloaded articles in 2009. We found the following major points. Most-cited articles show that transgenic plants and biofuels are clearly emerging topics since 2007 whereas soil carbon and climate change are the major mainstream topics of the last 10 years. Topic hits analysis allows to rank topics by mean emergence date, e.g. 2008.3 for 'genetically modified' and 2005.3 for 'irrigation'. Accordingly the 10 most emerging topics over 1999-2009 are biofuels, genetically modified, conservation agriculture, urban agriculture, sociology, organic farming, carbon sequestration, phytoremediation, mulch, and biodiversity. Analysis of most downloaded articles in 2009 show the predominance of topics such as carbon, climate, biodiversity, biofuels, pollutants, beneficial microbes, transgenic plants, and organic farming. Second, we reviewed selected articles published in 2009 with emphasis on emerging topics. We find that sociology is clearly bringing novel and unexpected findings to design sustainable agriculture. ...

We find that sociology is clearly bringing novel and unexpected findings to designing sustainable agriculture. Transgenic crops are highly innovative but show many unknowns that need to be carefully studied using various disciplines. Climate change has many scientifically proven effects on terrestrial ecosystems and agriculture. Here, soil carbon loss should be of particular attention because it rules the long-term fate of many factors such as atmospheric CO2, erosion, and water and nutrient supply. Biodiversity loss due to industrial monocropping is leading scientists to disclose alternative, more diverse cropping systems that optimise biodiversity, pest control and yield

En accès libre ; International audience ; Studies have shown that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can appear in feces within three days of infection, which is much sooner than the time taken for people to develop symptoms and get an official diagnosis (Mallapaty 2020). Therefore, earlier identification in wastewater of the virus's arrival in a community might limit the health and economic damage caused by the coronavirus disease 2019 (COVID-19). Despite centuries of technological advances, the COVID-19 pandemic is highlighting the limitations of our ability to control viral spread and infections worldwide. This knowledge gap has induced highly variable and sometimes contradictory government decisions in many countries, such as whether to wear a mask or not, and various strategies for testing, contact tracing and isolation of infected patients. The failure of control strategies has led many countries to lockdowns. In particular, powerful and rapid analytical techniques are actually still missing because virus detection is a key step in controlling viral transmission. The biomarker approach, which was initially developed in geochemistry to measure the maturity of dead organic matterand to link molecular fossils with biological homologs, has been applied to modern samples such as soils, sediments, wastewaters and plants (Albrecht and Ourisson 1971; Lichtfouse et al. 1994 1997; Bryselbout et al. 1998; Payet et al. 1999; Dsikowitzky and Schwarzbauer 2014; Choi et al. 2020). Here, we discuss the emergence of wastewater epidemiology based on ribonucleic acid (RNA) biomarkers, a discipline linking biomedical and environmental sciences for the detection of pathogens, with focus on analytical challenges.
