Agriculture, globalization, and ecological footprint: the role of agriculture beyond the tipping point in the Philippines

How to synergize ecological restoration to co-benefit the beneficial contributions of nature to people on the Qinghai-Tibet Plateau?

Understanding the magnitude and spatial distribution of ecological restoration requires a precise assessment of the beneficial contributions of nature to people. However, where the restoration areas should be located and whether the natural contribution of a compensation area can satisfy people's needs in the context of ecological degradation remain unclear. To address these issues, we selected the Qinghai-Tibet Plateau as the study areas, utilizing the offset portfolio analyzer and locator model to identify the compensation sites that offset the losses of ecosystem services and biodiversity resulting from ecological degradation. These compensation sites were developed through two offset types: restoration and protection. Then, based on the offset sites, we assessed nature's contribution to people (NCP) under the current status and future scenarios in terms of various aspects, including the habitat (NCP1), climate change (NCP4), and water quantity and flow regulation (NCP6). This study found that the area impacted by agricultural development was 7.15 × 105 ha, and the required compensation area was 5.5 × 106 ha under the current status. The ratio of the impacted area to the required area was approximately 7.0 in the future scenarios. The average habitat qualities were 0.14 and 0.30, while the mean NCP1 values were 2.69 and 0.51 in the protection and restoration offset sites, respectively. Moreover, based on the offset sites, the high-value contributions in NCP4 accounted for 18.64%-22.69% and 38.87%-46.17% of the total offset sites in terms of the restoration and protection offset types, respectively. Additionally, the estimated high-value contributions in NCP6 accounted for 58.35%-59.02% and 84.40%-95.86% of the total offset sites in the restoration and protection offset types, respectively. Our findings highlighted the significance of ecological restoration in showcasing the role of NCPs. These results could aid conservation managers in developing more targeted ecological strategies to enhance human well-being.

Towards a green future for Sub-Saharan Africa: do electricity access and public debt drive environmental progress?

The combination of rising debt levels, poor electricity access, and environmental deterioration could threaten the attainment of the sustainable development goals (SDGs). Hence, this inquiry examined the implications of public borrowing and access to electricity on environmental sustainability (proxied by ecological footprint (ECOL) and carbon dioxide (CO2) emissions) in Sub-Saharan Africa (SSA), largely overlooked in the literature. In addition to pre-estimation, diagnostic, and robustness checks utilized in the study, the instrumental variable generalized method of moment (IV-GMM) approach is employed to examine annual data from 39 SSA economies between 2005 and 2018. The key findings indicate that public debt negatively influences environmental sustainability in the region at a certain level of threshold, while access to electricity has the potential to trigger environmental sustainability but remain below the expected threshold to mitigate environmental damage in SSA. The study provides recommendations for SSA policymakers to significantly reduce pollution and protect the environment which is vital for sustainable development.

A dynamic relationship between renewable energy, agriculture, globalization, and ecological footprint of the five most populous countries in Asia

This study aims to examine the impact of globalization, renewable energy consumption, and agricultural value addition on the ecological footprint of selected five most populous countries in Asia during the period 1975-2020. The Westerlund cointegration test supports long-term cointegration relationships among the considered variables in selected countries. The long-term resilience results of the second-generation cross-sectionally augmented autoregressive distributed lag approach evidently demonstrate that agricultural value addition and globalization contribute significantly to the long-term ecological footprint of the five most populous countries in Asia. However, renewable energy consumption significantly reduces the ecological footprint. Moreover, the impact of economic growth on ecological footprint is significantly positive, while the square of economic growth had a significantly negative impact on ecological footprint, thus validating the inverted U-shaped environmental Kuznets curve hypothesis for specific Asian densely populated countries. The causality test results of Dumitrescu and Hurlin support the feedback hypothesis by showing a two-way causal relationship between renewable energy consumption and economic growth. There is also a two-way causal relationship between agricultural value added and ecological footprint. Strategically, specific densely populated countries in Asia should encourage clean energy production and consumption in the agricultural sector, and the adoption of environmentally friendly technologies can improve environmental quality and agricultural production.

Renewable energy, forest cover, export diversification, and ecological footprint: a machine learning application in moderating eco-innovations on agriculture in the BRICS-T economies

The United Nations Climate Change Conference (COP26) recommended that the member nations enhance their technological progression and structural transformation to mitigate the problems of climate change. The BRICS-T countries consisting of Brazil, Russia, India, China, South Africa, and Turkey agreed to implement COP26's policy suggestions. These countries accounted for 40% of global greenhouse gas emissions in 2017, thus posing severe threats to the global environment. The current study explores the role of renewable energy, forest depletion, eco-innovations, and export diversification in impacting the ecological footprint for those BRICS-T countries. We further examine the moderating effect of eco-innovations on agriculture on the BRICS-T nations. The study contributes to the existing literature by providing newer empirical insights on how eco-innovations and export diversification, along with renewable energy, forest cover, and agriculture, affecting the ecological footprint in the BRICS-T nations. It utilizes novel empirical methods like parametric and non-parametric techniques to derive the short-run and long-run empirical results. The empirical findings based on the augmented mean group and the kernel regularized least square methods document that economic growth, agriculture value added, and forest depletion increase the ecological footprint. In contrast, renewable energy and eco-innovations decrease the level of ecological footprint. In the long run, a 1% rise in GDP leads to a rise in the ecological footprint by 0.64% using the augmented mean group (AMG) estimation. The mean marginal effects are - 0.27%, 0.29%, and 0.17% for renewable energy; agriculture and forest cover, respectively, using the kernel-based regularized least square methods. The study suggests that policies designed for controlling the ecological footprints focus on the use of energy efficient technologies, particularly in the agricultural sector.

Does financing SMEs guarantee inclusive growth and environmental sustainability in the European union?

At the heart of the EU cohesion policy and the European Green deal lies the underlying sub-goals not limited to; financing the transition, promoting economic well-being of regions, take everyone along, achieving climate neutrality and a zero pollution Europe which the small and medium enterprises positions as the perfect conduit to achieve the aforementioned sub-goals in the case of Europe. Our study seeks to investigate if credit flowing from private sector units and government-owned enterprises to SMEs guarantees inclusive growth and environmental sustainability in EU-27 member states using data collected from OECD Stat. Database and the World Bank database from 2006 to 2019. Findings from the econometric analysis shows that SMEs activities is a significant and positive predictor of environmental pollution in the EU. In the case of inclusive growth countries cohort in the EU, both credit flowing from private sector funding institutions and government-owned enterprises to SMEs enhances a positive SME growth impact on environmental sustainability. In the case of non-inclusive growth countries cohort in the EU, credit flowing from private sector to SMEs enhances the positive impact of SME growth on environmental sustainability while credit flowing from government-owned enterprises to SMEs intensify the negative impact of SME growth on environmental sustainability.

Environmental sustainability, small and medium enterprises, and finance in Africa: a triplicate relationship

The age-long debate between SME-growth nexus has ignored environmental sustainability, as evident by many previous empirical studies. However, the pivotal role of SMEs and their undeniable dominance in the business landscape of Africa presents itself as a potential instrument for leading sustainability advocacy on the African continent. The study investigates whether credit flows from the private sector and government-owned enterprises to small and medium enterprises guarantee growth and environmental sustainability using data from World Bank Databases for 35 African countries from 2006 to 2019. Results from the econometric analysis show that domestic credit flowing from the private sector and government-owned enterprises to SMEs leads to significant growth with greater impact at lower quantiles in the case of Africa. On the issue of environmental sanctity, credit flowing from the private sector to SMEs counteract the adverse effect of SMEs activities on the environment, while credit flowing from government enterprises intensify the negative effect of SMEs activities on the environment in the case of Africa. Furthermore, renewable energy significantly reduces environmental decay more efficiently in upper quantiles while natural resource rents aggravate environmental decay only for African countries in the lower quantiles. Policy recommendations are proffered in the manuscript within the ambit of the study findings.

Revisiting the environmental Kuznets curve hypothesis with globalization for OECD countries: the role of convergence clubs

This paper aims to investigate the role of globalization in ecological footprint for Organization for Economic Cooperation and Development (OECD) countries during the 1981-2015 period with the environmental Kuznets curve (EKC) framework. To do so, unlike the existing literature, we follow a different path. Firstly, we test the environmental convergence (EC) hypothesis using the Phillips and Sul, Econometrica 75(6): 1771-1855, (2007) methodology. Then, we examine the impact of globalization and energy consumption on the ecological footprint (EF), and test the existence of the EKC hypothesis using the dynamic ordinary least squares mean group (DOLSMG) estimator. The convergence test results indicate that OECD countries do not converge to the same steady-state levels with regard to EF levels. However, we identify two convergence clubs that converging to a different steady-state equilibrium. The results of DOLSMG reveal that the EKC hypothesis is valid for both convergence groups. Furthermore, the impact of energy consumption and globalization on EF is higher for club 2, which includes developing countries.

Analysing the co-benefit of environmental tax amidst clean energy development in Europe's largest agrarian economies

The increasing human activities amidst competition for resources across the globe has made environmental challenges an ongoing classic problem, thus prompting policymakers to continually seek effective solution while ensuring sustainable development. With the wide coverage of the relevance of the double dividend hypothesis in explaining the co-benefit of environmental tax, there is a dearth of evidence in the literature to suggest that environmental tax offers green dividends for both the environment and agricultural practice in the European countries. As such, this study employed the more recent Method of Moments Quantile Regression (MMQR) alongside other approaches for Europe's largest agrarian economies (France, Germany, Italy, and Spain) over the annual period 1995-2020. The investigation affirms the validity of the co-benefit of environmental tax as far as environmental sustainability and value-added to agriculture are concerned in this panel of 'Big Four' economies, thus motivating the countries to relentlessly pursue the carbon-neutral 2050 target. Moreover, the study aligns with the expectation that renewable energy utilization and population density are desirable factors for achieving a carbon-neutral target. Lastly, the findings suggest that environmental quality is attainable in the panel, especially as increasing income surpasses a certain threshold, thus validating the environmental Kuznets curve hypothesis. Above all, the findings provide timely policy insight that accommodates both the environmental sustainability and food security framework of the European Union. The policy options relevant in light of the study's conclusions include that the decision makers in the selected agrarian economies should ramp up energy transition opportunities through a resilient environmental tax system that incentives availability of credit and investment financing in the agriculture sector.

Assessing the nexus between energy consumption, urbanization, and carbon dioxide emissions: does human capital matter?

This study is intended to add to the existing body of knowledge by examining the relationship between environmental pollution, human capital, energy use, and urbanization in 7 selected ASEAN (Association of South East Asian Nations) countries from 1990 to 2019. The cross-section augmented Dickey-Fuller and cross-section augmented Im, Pesaran, and Shin (CADF and CIPS) are applied based on the cross-sectional independence test results, and the feasible generalized least squares (FGLS) and the spatial correlation consistent standard error (PSCC) are employed for empirical results. The findings indicated that the variables have a positive long-run relationship. The human capital-energy consumption interaction contributed to environmental quality improvement. Thus, the study concludes that human capital is crucial in the energy-environment relationship. ASEAN nations are advised to adopt laws and treaties to provide a healthy environment that help to keep carbon dioxide emission as low as possible.

Do bureaucratic policy and socioeconomic factors moderate energy utilization effect of net zero target in the EU?

Based on the commitment to improve environmental quality across European Union under the United Nations' Sustainable Development Goals and varying national goals, this study investigates the dynamic linkages between bureaucracy, socioeconomic factors, conventional fossil fuel energy consumption vis-à-vis aggregate fossil and disaggregate fossil (oil, coal, and gas) fuels and environmental quality in the panel of selected 25-EU nations for the period 1990-2017. The study employs relevant second-generation empirical method and unearth the following results: (1) inverted environmental Kuznets curve was validated while fossil fuel consumption has a deteriorating impact on environmental performance due to its positive effect on carbon emission; (2) fossil fuel energy consumption (both aggregate and it components) exerts a dampening impact on environmental performance due to its positive effect on carbon emission; (3) that direct effect of bureaucracy and socioeconomic factors promote environmental quality but the degree or magnitude of influence is significantly different between bureaucratic system and socioeconomic factor, and (4) the moderating or indirect impact of bureaucracy, socioeconomic on the environment via fossil fuel energy consumption is observed and significantly different across the model specification. Moreover, the result reveals a unidirectional causal relationship flows from GDP per capita, bureaucracy and socioeconomic factors to carbon emission, while bi-directional relationships between oil, gas and carbon emission are established. In policy direction, the study therefore recommend that the European Union member countries should further explore the opportunities in clean energy development in order to ameliorate the continent's environmental concerns. Furthermore, in the quest to scale up the bloc's energy transition, significant improvement in the countries' bureaucracy establishment and socioeconomic conditions could hasten the energy transition and efficiency policy while improving the environmental sustainability drive.
