Making the Complicated Simple:A Minimizing Carrier Strategy on Innovative Nanopesticides

The flourishing progress in nanotechnology offers boundless opportunities for agriculture,particularly in the realm of nanopesticides research and development.However,concerns have been raised regarding the human and environmental safety issues stemming from the unrestrained use of non-therapeutic nanomaterials in nanopesticides.It is also important to consider whether the current development strategy of nanopesticides based on nanocarriers can strike a balance between investment and return,and if the complex material composition genuinely improves the efficiency,safety,and circularity of nanopesticides.Herein,we introduced the concept of nanopesticides with minimizing carriers(NMC)prepared through prodrug design and molecular self-assembly emerging as practical tools to address the current limitations,and compared it with nanopesticides employing non-therapeutic nanomaterials as carriers(NNC).We further summarized the current development strategy of NMC and examined potential challenges in its preparation,performance,and production.Overall,we asserted that the development of NMC systems can serve as the innovative driving force catalyzing a green and efficient revolution in nanopesticides,offering a way out of the current predicament.

Bio-Economic Strategy to Combat Non-Point Pollution in China

While non-point pollution from agriculture has become an increasingly serious problem in China, some progress has been made in studying the causal biophysical processes. However, few studies have assessed the economic consequences of non-point pollution in China or the policy options that could be employed to combat it. In this work a sustainable strategy to control non-point pollution from crop production, which involved taxing excessive inputs of irrigation water and fertilizer, was proposed. The approach taken to assess these measures combined biophysical and economic models,having a trade-off between economic returns and an improved environment. A proven and practical spatially referenced water and nutrient management model was used to determine the quantities of excessive irrigation water and fertilizer for specific soil and land use. Also, a set of indicators were proposed for evaluating the effects of agricultural economic output and agricultural practices on the environment.

Sustainable Energy Development Strategy in China

Energy and electrical power is very important in economy and society. China has faced an increasingly serious energy shortage in the past decade. On the other hand, energy consumption and power generation, releasing carbon dioxide and other gaseous emissions from fossil fuels, may pollute the environment. Nuclear power, as an alternative energy source, would reduce these gaseous emissions. Both global warming and sustainable energy supply can be solved to some extent by the application of nuclear power. In the aspects of regaining economic advantages, environmental protection, the security and reliability of energy, nuclear power has an obvious superiority. In this paper, we present the energy status in quo of China, and discuss ways to realize the sustainable development of energy and power.

The Influence of Public Policies on Urban Mobility： A Comparative Study between Porto Alegre （Brazil） and Washington D.C. （United States）

Increasing urbanization rates observed in the last decades have significantly contributed to a higher number of travelers to urban environments. The objective of this study was to identify measures and factors that encourage the use of alternative transportation in the cities of Washington D.C., USA and Porto Alegre, Brazil. The methodology used to compare these two cities was an evaluation of their urban mobility plans, including strategic analyses and measures to promote the use of public transport. This approach was based on factors described in the following document： ＂Urban Sustainability： Impacts of Economic Development and Their Consequences on the Process of Urbanization in Emerging Countries＂, prepared by the United Nations. The results indicate different planning strategies, ranging from focusing on tax integration policies in order to become more financially attractive to the user, to using different modes of mass transportation integrated with active mobility. In Washington D.C., an innovative strategy was developed in preparation to forecast scenarios, as the measures comprised projection for the year 2040, which will respond to mobility demands in the coming decades.

Quality of the Built Environment from the Infrastructure of Social Interest Housing Developments

The structures in the built environment, particularly concerning morphology are reflected in different allotments, which rely heavily on a technical insight. They are constantly attributed in Brazil by architects, urban planners and geographers, among others, who plan the space and structure them for providing for the population needs. In this context, this research aims to analyze the morphological structure of two social interest housing developments, considering that the lack of efficiency in construction has generated infrastructure problems. Specifically, we analyzed the layout of the two housing developments of social interest, morphology recurrence, layout style adopted, relating their characteristics. Results have shown that the more regular is the topography, the more is the reduction of deployment costs execution of the infrastructure in the housing development. It is believed that this research can provide discussions on the subject and present subsidies to architectural projects.

Strategies for Sustainable Development of Broadband Services

This article explains that Internet services, characterized by Instant Messaging (IM), are now, more than ever, strongly influencing and changing the traditional telecom services as well as industry-operating model. To adapt to the change, telecom operators should adjust their thoughts while developing new broadband services. The paper will discuss the strategies for operators to make sustainable development in broadband services. It recommends operators to should become telecom-grade public service platform providers, to pay more attention to the development of next generation Service Delivery Platform (SDP), and to strengthen R&D efforts on non-PC broadband terminal because it is an important driving force for continuous development of broadband services.

Research progress in assessment and strategies for sustainable food system within planetary boundaries

Meeting the increasing food demand in a manner that ensures both resources and environmental sustainability poses a global challenge.The conceptual framework of planetary boundaries(PBs)has emerged as a crucial reference in the study of sustainable food system,with specific focuses on key dimensions such as land use change,freshwater use,nitrogen(N)and phosphorus(P)cycles,and greenhouse gas(GHG)emissions.In this study,we summarized the threshold applications of PBs in sustainable food system research at both the global and national(China)scales.Based on these thresholds,we evaluated the sustainability conditions of the food system,considering resources such as cropland,freshwater,N and P applications,as well as environmental impacts including N and P losses,and GHG emissions.In addition,we explored the impacts of single or combined management strategies on sustainable food systems.These strategies included dietary changes,improvements in technologies and management,reductions in food loss and waste,and optimization in agricultural production distribution.Finally,we outlined future research directions in sustainable food system,including enhancing research on the interaction mechanisms among PBs elements within food systems,conducting downscaling studies of PBs elements at national and regional levels,and ensuring the rationality of policy-making for sustainable food systems in China.This study can provide a theoretical foundation and strategies guidance for sustainable food system and agricultural land use management in the future both globally and in China.
