Mountain ecosystems play an essential role in supporting regional sustainable development and improving local ecological environments. However, economic development in mountainous areas has long been lagging, and multiple conflicts related to resource assurance, ecological protection, and economic development have emerged. An accurate grasp of the current status and evolutionary trends of mountain ecosystems is essential to enhance the overall benefits of ecosystem services and maintain regional ecological security. Based on the In VEST(Integrated Valuation of Ecosystem Services and trade-offs) model, this study analyzed the spatiotemporal evolution patterns and the trade-offs and synergies among ecosystem services(ES) in the Dabie Mountains Area(DMA) of eastern China. The Markov-PLUS(Patch-generating Land Use Simulation) model was used to conduct a multi-scenario simulation of the area's future development. Water yield(WY) and soil conservation(SC) had overall increasing trends during 2000-2020, carbon storage(CS)decreased overall but slowed with time, and habitat quality(HQ) increased and then decreased. The ecological protection scenario is the best scenario for improving ES in the DMA by 2030;compared to 2020, the total WY would decrease by 3.77 × 10^(8) m^(3), SC would increase by 0.65 × 10^(6) t, CS would increase by 1.33 × 10^(6) t, and HQ would increase by 0.06%. The comprehensive development scenario is the second-most effective scenario for ecological improvement, while the natural development scenario did not have a significant effect. However, as the comprehensive development scenario considers both environmental protection and economic development, which are both vital for the sustainable development of the mountainous areas, this scenario is considered the most suitable path for future development. There are trade-offs between WY, CS, and HQ, while there are synergies between SC, CS, and HQ. Spatially, the DMA's central core district is the main strong synergistic area, the marginal zone is the weak

Studies on mainstreaming climate-smart agriculture(CSA)practices can increase smallholder farmers’capacity and awareness to improve food security and establish sustainable livelihoods through resilient agricultural systems,while achieving adaptation and mitigation benefits.Hence,valuable insights can be obtained from smallholder farmers in responding to present and forthcoming challenges of climate change impacts.However,there is little research work on trade-off and synergy assessments.Taking Geshy watershed in Southwest Ethiopia as a case study area,both quantitative and qualitative data analysis were undertaken in this study.The data were collected from 15 key informant interviews,6 focus group discussions,and 384 households to answer the following questions:(1)what are the top 5 preferred CSA practices for smallholder farmers in Geshy watershed when coping with the impacts of climate change?(2)What is the performance of the preferred CSA practices?And(3)which trade-offs and synergies are experienced upon the implementation of CSA practices?The study came up with the most preferred CSA practices such as the use of improved crop varieties,small-scale irrigation,improved animal husbandry,the use of efficient inorganic fertilizers,and crop rotation with legumes.The selected CSA practices showed that the productivity goal exhibit the best synergy,while the mitigation goal has trade-offs.The study also indicated that the use of improved crop varieties causes high synergies in all 3 goals of CSA practices;small-scale irrigation provides a medium synergy on productivity goal but high synergy for adaptation and mitigation goals;improved animal husbandry shows a high synergy with the adaptation goal,a relatively lower synergy with the productivity goal,and a trade-off with the mitigation goal;the use of efficient inorganic fertilizers shows maximum synergy for the productivity and adaptation goals;and crop rotation with legumes exhibits high synergy with the productivity and mitigation goals but a relatively lower syne

trade-offs between plant growth and immunity are a well-known phenomenon in plants that are meant to ensure the best use of limited resources.Recently,many advances have been achieved on molecular regulations of the trade-offs between plant growth and immunity.Here,we provide an overview on molecular understanding of these trade-offs including those regulated at the transcriptional level or post-transcriptional level by transcriptional factors,microRNAs,and post-translational modifications of proteins,respectively.The understanding on the molecular regulation of these trade-offs will provide new strategies to breed crops with high yield and enhanced resistance to disease.

Climate change adaptation strategies provide a cushion for smallholder farmers,especially in subSaharan Africa against the risks posed by climate hazards such as droughts and floods.However,the decision-making process in climate adaptation is complex.To better understand the dynamics of the process,we strive to answer this question:what are the potential trade-offs and synergies related to decision-making and implementation of climate adaptation strategies among smallholder farmers in sub-Saharan Africa region?A systematic literature review methodology was used through the Preferred Reporting Items for Systematic Review and Meta-Analysis(PRISMA)statement with the four-stage inclusion/exclusion criteria to identify the literature from selected databases(Scopus and Google Scholar).The climate adaptation strategies are organized into five broad categories(crop management,risk management,soil/land management,water management,and livestock management strategies).Evidence suggests that potential trade-offs may arise concerning added costs,additional labor requirements,and competition among objectives or available resources.The synergies,on the other hand,arise from implementing two or more adaptation strategies concurrently in respect of increased productivity,resilience,yield stability,sustainability,and environmental protection.trade-offs and synergies may also differ among the various adaptation strategies with minimum/zero tillage,comparatively,presenting more tradeoffs.The development and promotion of low-cost adaptation strategies and complementary climate adaptation options that minimize the trade-offs and maximize the synergies are suggested.Skills and knowledge on proper implementation of climate change adaptation strategies are encouraged,especially at the local farm level.

Natural ecosystems provide human society with very important products and services. With the rapid increase in population and the over-exploitation of natural resources, humans are continually enhancing the production of some services at the expense of others. This paper estimates changes in ecosystem services, and the relationship between these services in the Guanzhong-Tianshui Economic Region of China. These ecosystem changes are of great significance to the sustainable development of this economic region. The concept of production possibility frontier （PPF） is applied to evaluate the trade-offs and synergy between carbon sequestration, water yield and soil retention. Three land use strategy scenarios - planning, exploitation and protection - are applied to evaluate potential changes in ecosystem services. This study reveals noticeable trade-offs between carbon sequestration, soil retention and water yield, with synergy between carbon sequestration and soil retention. There are synergies between carbon sequestration, water yield and soil retention in the three scenarios. The protection scenario is the most favourable land use strategy for regulating ecosystem service capacity. This scenario results in the highest carbon sequestration, water yield and soil retention. The results could have implications for natural capital and ecosystem services planning, management and land use decision-making.

Polymer electrolytes(PEs)have been long recognized as the key materials to enable energy-dense batteries and render flexible energy devices practically viable,owing to their chemical and mechanical reliability.However,much of their promise is yet to be realized.The roomtemperature ion conductivity of existing PEs still falls short of the implementation criterion of 10^(-4) S cm^(-1) on the promise of acceptable mechanical properties,thereby precluding their practical application.The twin but inversely related duties of polymers,that is,functioning as both an ion-conducting medium and a structural backbone,underlie this issue but are less elucidated systematically.The polyacrylate(PA)family is among promising polymer matrices on account of ester polarity,electrode compatibility,chemical tunability,and mechanical durability.The extensive applicability of PA in plasticized gels,dry solids,and emerging composites makes PA-based PEs representative to illustrate the trade-off between ion conduction and mechanical strength.We herein seek to outline the stated long-standing conflict exemplified by PA-based PEs,focusing on crucial strategies toward balancing and reconciling the two mutually exclusive properties,with the intention of offering designing guidelines for next-generation PEs.

Globally,urban land expands at a faster rate than the corresponding urban population,which comes at a cost of agricultural and natural land.Wealth has been identified as an underlying driver of this trend,but it is unclear whether more prosperous cities inevitably have a greater urban land consumption.Here,we map urban pros-perity indicators to their relevant Sustainable Development Goals(SDGs)for 64 major world cities and relate these to the corresponding urban land consumption(defined here as built-up land per capita).Results indicate a moderately-weak but significant correlation between overall prosperity and urban land consumption(Spear-man’s correlation,𝜌ρ=0.47,ptrade-offbetween both.In addition,we find a regional clustering,with for example cities with relatively low prosperity and low urban land consumption in Africa,and cities with high prosperity and low-to-medium urban land consumption in Europe.The moderately-weak correlation in combination with these regional differences suggests that the observed trade-offis avertable and that other drivers moderate this relation.Consequently,cities can increase their prosperity without additional environmental consequences entailing land take and the conversion of natural and agricultural land.

The 2030 Agenda for Sustainable Development is a prospect for the future development of all countries in the world.Its core is to set up the Sustainable Development Goals for the year of 2030,and develop a series of institutional mechanisms around SDGs to promote its implementation.The SDGs include 17 goals,of which SDG 11 is to make cities and human settlements inclusive,safe,resilient and sustainable.Green building can play a positive role in the implementation of SDG 11.However,the entire process of green building development involves multiple stakeholders and various professional fields,which play different roles where may be positive synergies or negative trade-offs in the whole process.This paper uses the nexus approaches to clarify how multiple stakeholders and professions interact with each other in the green building development with the aim of promoting SDG 11.

Understanding the trade-offs among ecosystem services(ESs)at multiple scales is a key challenge to effective environmental management.However,the scale effect of ESs trade-offs in the Qinghai-Tibetan Plateau(QTP)has received little attention.This study investigated the scale effects of ESs trade-offs in Bailongjiang Watershed(BLJW),a typical transitional ecotone from the Loess Plateau to the Tibetan Plateau with multiple ESs,intensive human activities and frequent geological disasters in the Eastern Margin of the QTP,China.Four key ESs including food supply(FS),soil conservation(SC),water conservation(WC),and habitat quality(HQ)in BLJW in 1990,2002,and 2016 were mapped to analyze the scale effects at the watershed,county,and township scales.The results indicated varying scale-related temporal and spatial relationships among FS,SC,WC,and HQ.The trade-offs between FS-SC and FS-WC initially increased and then decreased during 1990-2002 and 2002-2016,respectively,while the trade-offs between SC-WC,SC-HQ,HQ-WC,and HQ-FS first decreased and then increased at the same period.The magnitudes of the trade-offs among the four ESs are in the order of watershed scale>township scale>county scale.Among the major land-use types in BLJW,the trade-offs between WC-FS and between HQ-FS in farmland and grassland were higher than those of other land uses.There is a strong trade-off between SC-HQ in forestland and a weak trade-off between SC-WC in farmland and grassland.The trade-offs between the six ESs pairs varied and were scale-dependent mainly due to spatial heterogeneity in the landscape and in human activities.Understanding the ESs trade-offs at the watershed,county,and township scales provides a scientific basis for the formulation of environmental management strategies at appropriate spatial scales.At the BLJW watershed scale,more attention should be paid on farmland and grassland planning and its management,also,forestland should be enlarged if possible.At the county and township scales,land consolidation and planning should
