Impact of taxes on the 2030 Agenda for Sustainable Development:Evidence from Organization for Economic Cooperation and Development(OECD)countries

Multiple ecological and socioeconomic problems have occurred worldwide,raising the awareness of sustainability.This study aims to examine the impact of taxes on Sustainable Development Goals(SDGs)in the context of Organization for Economic Co-operation and Development(OECD)countries.This research used effective average tax(EAT),tax on personal income(TPI),tax on corporate profits(TCP),and tax on goods and services(TGS)as the variables of taxes,and employed secondary data from 38 OECD countries covering 2000–2021.The study also used Breusch-Pagan Lagrange Multiplier(LM),Pesaran Scaled LM,Bias-Corrected Scaled LM,and Pesaran Cross-sectional dependence(CSD)tests to analyze the existence of crosssectional dependency.Then,we established the stationarity of variables through second-generation panel unit root tests(Cross-sectional Augmented Dickey-Fuller(CADF)and Cross-sectional Im,Pesaran,and Shin(CIPS)),and confirmed the long-run cointegration of the variables by using secondgeneration panel cointegration test(Westerlund cointegration test).The results showed that EAT,TPI,TCP,and TGS are positively associated with SDGs.However,the change in TPI has a smaller effect on SDGs than the change in EAT or TCP or TGS.The result of panel causality indicated that EAT,TPI,and TGS have a unidirectional causal relationship with SDGs.The study also found that TCP has a bi-directional causal relationship with SDGs.Moreover,the finding indicated that the OECD countries need to focus on tax policies to achieve the 2030 Agenda for Sustainable Development.This study is based on the theory of optimal taxation(TOT),which suggests that tax systems should be designed to maximize social welfare.Finally,we suggests the importance of taking a comprehensive approach for the managers and policy-makers when analyzing the impact of taxes on SDGs.

Hallmark of a Resilient City: Adoption of Green Infrastructure in African Cities

Dynamic urbanization of African cities has created development trajectories that face systemic challenges in the provision of sustainable and ecologically resilient urban environments. The specific challenges include extensive unregulated growth with informal settlements reflecting poor service levels and high poverty indices, inadequacy in provision of basic services in health, water, housing, transport and communication infrastructure, high reliance on biomass fuels, exposure to environmental stress and implausible climate change coping and mitigation mechanisms among others. Review of extensive literature and synthesis of existing bodies of knowledge on the ecological and management perspectives of urban environments revealed many gaps and understanding of urban transformation processes. The purpose of this review was to contextualize credible pathways for optimization of both ecosystem goods and services from green urban landscapes (Green infrastructure) and non-green infrastructure to ensure sustainable and ecologically resilient urban environments. Attempts were made to rationalize and validate through discussions the benefits of managed urban ecosystems for African cities. On the basis of the evidence from the literature, it is concluded that urban development trajectories that do not embrace multifaceted approaches that deliberately retain and maintain green infrastructure in the urban environment may not be cost-effective. It is recommended that systematic integration of urban forestry concepts in urban planning that involves communities, local and national governments, business entrepreneurs and public and private research institutions provides tenable frameworks for addressing current and future challenges of urbanization in Africa.

Modern concepts of soil conservation

Approaches to soil conservation are in constant evolution and improvement.This paper summarizes some of the modern approaches,ranging from no till to conservation agriculture to sustainable land management.These approaches are not separate,but components of a continuum of conservation approaches applicable at different levels and different scales.No tillage is important at the detailed,farm level,while CA and SLM are important at the farming systems and corporate levels.The successes achieved with no till in Argentina(also Brazil,Paraguay,Uruguay,Mexico,Canada,Australia,and others)illustrate how these concepts relate to each other.

Evolving concepts and opportunities in soil conservation

The terrestrial landscape has changed considerably compared to that of the early 20th century when soil conservation was first institutionalized.Large portions of the land are already intensively managed,and the remainder is increasingly receiving human interventions.Previous work on soil conservation focused attention on technological innovations,particularly control and mitigation of soil erosion.However,land degradation has continued and actually accelerated in many parts of the world,due mainly to demands for continued economic development,using technologies that are highly exploitive.In many cases,this has been facilitated by highly inadequate and unsympathetic institutional,legislative,and policy environments.The paper discusses some of the new driving forces,new international programs,and new potential partners in soil conservation.Increasingly,international efforts to mitigate land degradation are shifting from studies of the biophysical processes to improving the global,national and local enabling policy environment,as well as mainstreaming of soil conservation into national and regional policies and programs.Also,increased emphasis is placed on economic instruments and international markets,such as carbon trading,and incorporation of non-market values in ecosystem investment,such as payment for ecosystem services,certification schemes,etc.The paper discusses some of the opportunities for soil conservation that accrue from these new driving forces.
