Aquatic ecosystems are one of the most threatened ecosystems in the world resulting in the decline of aquatic biodiversity. Monitoring and the assessment of aquatic ecosystems are necessary to protect and conserve these ecosystems as monitoring provides insights into the changes in the aquatic ecosystem over a long period of time and assessment indicates the status of these ecosystems. This paper presents an overview of different methods for the hydromorphological, physical–chemical and the biological monitoring and assessment of surface waters. Furthermore, recently developed monitoring and assessment methods are discussed to support sustainable water management and contribute to the implementation of the Sustainable Development Goals 6 (SDG6 related to clean water and sanitation) and 15 (SDG15 related to terrestrial and freshwater systems) of the United Nations. However, many other SDGs are dependent on freshwater, such as food (e.g., SDG2) and climate-related SDGs. We presented an innovative concept for integrated monitoring and assessment. The main new elements are the monitoring of all communities and the use of integrated socio-environmental models to link these communities to ecosystem interactions and functions as a basis for determining their relation to the SDGs. Models can also allow to determine the effects of changes in SDGs on the different elements of the concept, and serve in this manner as tools for the selection of an optimal balance between the SDGs in the context of sustainable development.

“…However, among these, soil fertility is considered as a crucial factor which has considerable impact on crop productivity (Blaise et al, 2004;Gete et al, 2010). Being a dynamic concept, soil fertility is affected by the climatic conditions of the area and cultural practices (Ayoub, 1999). Abstract | Use of organic manures in agriculture is considered as environmental friendly, carbon smart and an economical approach to get maximum output in existing agricultural production systems.…”

“…Along with the increasing in agricultural productivity, there is an improvement in the use of mineral fertilizers. Though, the excessive consumption of mineral fertilizers has roused environmental concerns, like eutrophication of fresh water bodies and proliferation of algal blooms in coastal waters (Ayoub, 1999) and economic impacts due to their high cost (Horrigan et al, 2002).…”

Molecular mechanisms involved in the bacterial talking and maize growth promotion With the increase of agricultural production, there is an improvement in the use of mineral fertilizers, which may cause different environmental problems, besides the soil salinization. A possible alternative for reducing the application of these products is the use of plant growth-promoting bacteria (PGPB), that can be used alone or in co-inoculation, resulting in an alternative environmentally and economically feasible. Better results can be obtained if the interaction among bacteria-bacteria and bacteria-plant be elucidated, and strategy developed to optimize these interactions. Thus, the plant growth-promoting Bacillus sp. RZ2MS9, previous described as a potential PGPB in maize and soybean, was GFP-tagged and monitored alone and co-inoculated with Azospirillum brasilense (Ab-v5::pWM1013) during maize colonization. The interaction of tagged strains in maize were monitored by fluorescent microscopy (FM) and quantitative PCR (qPCR), demonstrating an endophytic behavior of Bacillus sp. RZ2MS9. Although the non-detection of Ab-v5::pWM1013, the co-inoculation resulted in the best increase in root and shoot dried weight, root volume and in root diameter, showing that inoculation with more than one strain can be a good choice to development of bio-fertilizers. One important system to bacterial interaction is the quorum sensing (QS). The QS is an important cell-cell communication system that allows bacterial cells to recognize their own population and modulate their gene expression. This, system is also involved in the interspecific communication, including other bacterial species and plants. In the other hand, enzymes able to detect and degrade these molecules evolved, the called quorum quenching (QQ) system, that has been evolved in some bacteria as competitive advantage for niches colonization. The aiiA gene, was one of the first gene related with the QQ in Bacillus. The aiiA was found in Bacillus sp. RZ2MS9 genome. Through construction of a new QQ biosensor, Agrobacterium tumefaciens At11006, and validated by A. tumefaciens NTL4, the ability of RZ2MS9 to degrade QS molecules was confirmed. The knockout of aiiA gene was performed using the CRISPR-Cas9 system, confirming this gene function. By these results, the influence of QQ system of Bacillus sp. RZ2MS9 during maize colonization and RZ2MS9-A. brasilense-maize can be better investigated, opens the possibility to better understand the role of QQ system in the interaction among PGPB and plants.
