The Future

Megatrends of population growth, urbanization and global warming are making it more and more difficult to find clean water for our needs. Global demand for fresh water grows at 2-3%/year while availability of fresh water has not been increasing. Regional differences in the growth rates are big. The main sustainability objective in water processes is balancing the demand – supply equation. Human impact on the atmosphere seems to aggravate the water availability problem. Over two thirds of global fresh water need is for agriculture. Current practices and technologies in managing water streams are not enough in the future.

Water Issues

Nursery and greenhouse producers, research and extension faculty, and representatives from allied fields collaborated to formulate a renewed vision to address water issues affecting growers over the next 10 years. The authors maintained the original container irrigation perspective published in “Strategic vision of container nursery irrigation in the next ten years,” yet broadened the perspective to include additional challenges that face nursery crop producers today and in the future. Water availability, quality, and related issues continue to garner widespread attention. Irrigation practices remain largely unchanged due to existing irrigation system infrastructure and minimal changes in state and federal regulations. Recent concerns over urbanization and population growth, increased climate variability, and advancements in state and federal regulations, including new groundwater withdrawal limitations, have provided an inducement for growers to adopt efficient and innovative practices. Information in support of the overarching issues and projected outcomes are discussed within.

Water Resources Utilization

Nanotechnology, as contemporary field of research in forming of materials and devices on the level of molecule and atoms, is founding broad utilization in different scientific and engineering domains. The influence of nanotechnology on the development of contemporary human society has got a significant potential in domains as economy, environment protection, health and improvement of the quality of life. The need for fresh water as a necessary resource for living world, as well as the economic activity on the level of humanity is growing in the conditions of increasing population, increasing economic activities and increasing pollution. In that sense the conventional methods for water treatment may become ineffective for providing sustainable utilization of water resources in the future. Nanotechnology as a contemporary scientific and engineering field is considered efficient and potentially, the only solution for sustainable utilization of fresh water in the future. The efforts in nanotechnology utilization for sustainability of fresh water resources mean comprehensive approach and clarity in defining goals as well as the ways for their realization. The basic expectations of nanotechnology in the sense of fresh water resources utilization are directed to enhancement of fresh water availability, increase of efficiency of fresh water delivery and enabling next generation systems for fresh water quality monitoring. The increase of fresh water availability by nanotechnology means development of filtering systems and development of membrane systems, inverse osmosis for water desalinization and catalysts for water treatment. Efficiency of fresh water delivery based on nanotechnology means reducing energy necessary for its transportation, developing system of pipes and components which are easier, stronger and which will last longer as well as to provide cheap materials which improve energy efficiency for heating and cooling. All these processes for nanotechnology development aiming to provide sustainable fresh water resources utilization require significant efforts on scientific and engineering level in order to be utilized in everyday life. This paper aims to research the state of the art of nanotechnology development in the domain of sustainable utilization of fresh water resources.

&lt;p&gt;The occurrence of severe haze events remains a serious problem in Beijing. Previous studies suggested that the frequency of weather patterns conducive to haze may increase with global warming. The new Shared Socioeconomic Pathways (SSPs) cover a wide range of uncertainties in aerosol and greenhouse gases emissions. Global and Chinese aerosol emissions are projected to decrease in most SSPs, while increases in greenhouse gases and global warming will continue for the rest of the century. The future, therefore, remains unclear.&lt;/p&gt;&lt;p&gt;We quantified the air pollution over Beijing and associated weather patterns using multiple indices calculated from the SSPs&lt;/p&gt;&lt;p&gt;We show that the occurrence of weather patterns conducive to the formation of haze significantly increases by the end of the century due to increases in greenhouse gases. Aerosol reductions also cause an increase in their occurrence, but reduce the severity of haze, and overall reducing aerosol emissions will be beneficial.&lt;/p&gt;
