Optimizing the function of ecosystem services (ESs) is vital for implementing regional ecological management strategies. In this study, we used multi-source data and integrated modelling methods to assess the spatiotemporal variations in eight typical ESs on the Chinese Loess Plateau from 2000 to 2015, including grain production, raw material provision, water conservation, carbon storage service, soil conservation, oxygen production, recreation, and net primary productivity (NPP) services. Then, we divided the ecosystem service bundles (ESBs) according to relationships among the eight ESs, obtaining four types of eco-functional areas at the county (city or banner or district) level based on the spatial clustering of similarities in different ES types. We also identified and assessed the contributions of influencing factors to these eco-functional areas using principal component analysis (PCA) across spatiotemporal scales. We found that the spatiotemporal variations in different ESs were noticeable, with an overall increase in grain production and soil conservation services, no significant change in carbon storage service, and overall decreases in raw material provision, water conservation, oxygen production, recreation, and NPP services. From 2000 to 2015, the number of significant synergistic ES pairs decreased, while that of significant trade-off pairs increased. To the changes of ESBs in the eco-functional areas, the results indicated that the indirect loss of these ESs from forest and grassland due to urban expansion should be reduced in ecological development area (ESB 2) and multi ecological functional area (ESB 3). Meanwhile, crop planting structures and planting densities should be adjusted to reduce ES trade-offs associated with water conservation service in grain-producing area (ESB 4). Lastly, ESB-based eco-functional zoning can be used to improve ecological restoration management strategies and optimize ecological compensation schemes in ecologically fragile area (ESB 1).

Sustainable development is the central theme of modern global development. With the arrival of the urban era, the vulnerability and instability of rural areas have significantly increased, and rural sustainable development faces serious challenges. To address these issues, the study took the Zaozhuang Innovation Demonstration Zone in China under the National Sustainable Development Agenda as a case, combined with 2016–2020 economic and social and land use data, and applied Granger causality test method to explore the theoretical and practical pathways of “innovation-driven rural sustainable development”. The results showed that rural sustainable development and economic sustainability displayed a trend of synergistic change, with “explosive” growth from 2018 to 2020. The social sustainability steadily increased from 2016 to 2020. Ecological and spatial sustainability continuously declined during the study period. Moreover, the rural innovation capacity of the Zaozhuang Innovation Demonstration Zone displayed rapid growth during 2016–2020. Although the rural innovation capacity of the Zaozhuang Innovation Demonstration Zone has rapidly improved, it has a weak driving effect on rural sustainable development and economic sustainability. There are two primary challenges that must be overcome to ensure the rural sustainable development of the Zaozhuang Innovation Demonstration Zone. The first challenge is the imbalance among the multi-dimensional relationships in the process of rural sustainable development, and the second challenge is the weakening of rural innovation capacity to drive rural sustainable development. To overcome these challenges, this study proposed a systematic pathway for rural sustainable development in the Zaozhuang Innovation Demonstration Zone from multi-dimensions, such as policy actions, technologies, projects, and institutional guarantees, and formed a universal and representative “Zaozhuang model”. This study expands the theoretical foundation of rural sustainable development and provides theoretical and practical support for innovation-driven rural sustainable development.

Climate change can have significant impacts on crop yields and food security. This study assessed the linkages between climate change and crop yields to obtain a better understanding on the drivers of food security. The study was conducted in Pasagaun village of Lamjung District in Nepal, where household surveys and focus group discussions (FGDs) were used to collect data including crop cultivation, irrigation facilities, and adaptation strategies. Moreover, climate data (temperature and precipitation) from 1992 to 2020 were collected from the Khudi Bazar meteorological station and crop yield data were obtained from the Agri-Business Promotion and Statistics Division. Trend analysis of temperature and precipitation was conducted using Mann-Kendall trend test and Sen's Slope method, and the results showed an increase in the average temperature of approximately 0.02 ​°C/a and a decrease in the annual precipitation of 9.84 mm/a. The cultivation of traditional varieties of rice and foxtail millet (Kaguno) has vanished. Although, there was no significant impact of the maximum temperature on the yield of rice and maize, the regression analysis revealed that there are negative relationships between rice yield and annual minimum temperature (r ​= ​−0.44), between millet yield and annual precipitation (r ​= ​−0.30), and between maize yield and annual minimum temperature (r ​= ​−0.31) as well as positive relationship between rice yield and annual precipitation (r ​= ​0.16). Moreover, average rice yield and millet yield have decreased by 27.0% and 57.0% in 2000–2020, respectively. Despite other reasons for the decrease in crop yield such as the lack of irrigation facilities, out-migration of farmer, and increased pest infestation, respondents have adopted adaptation strategies (for example, shifts in cultivation time and changes in crop types) to minimize the impacts of climate change. More investigation and community-based farming education are needed to understand and alleviate the harmful impacts of climate change on crop yield, as effective adaptation coping strategies are still insufficient. This study provides insights into the adaptation strategies that are necessary to keep food security in the face of climate change.

This study aims to assess the small ruminant value chain in Al-Ruwaished District, Jordan, to identify the potential intervention areas that could improve the production efficiency and guarantee the sustainability of the small ruminant sector in this area. Sheep breeding is the source of livelihood for most of the people in Al-Ruwaished District, which is characterized by the large number of sheep and goats. We surveyed 5.0% of the small ruminant holders in the study area and conducted individual interviews and surveys with the potential actors in the value chain to undertake a small ruminant value chain analysis. From the survey, we found that the small ruminant value chain consists of five core functions, namely, input supply, production management, marketing, processing, and consumption. Despite the large number of holdings that gives an impression of the stability to the small ruminant sector, the surveyed results show a clear fragility in the value chain of small ruminants in this area. The small ruminant production system is negatively impacted by climate change, especially continuous drought. In addition, the high prices of feed that the farmer cannot afford with clear and real absence of the governmental and non-governmental support activities also impact the development of the value chain. The results of strengths, weaknesses, opportunities, and threats (SWOT) analysis reveal that the major constraints faced by this value chain could be divided into external and internal threats. Specifically, the most prominent external threats are the nature of the desert land and continuous drought, while the major internal threats are the absence of appropriate infrastructure, shortage of inputs, and weakness in the production management and marketing. We proposed solutions to these challenges to ensure the sustainability and effectiveness of the sector, such as the formulation of emergency response plans to severe weather, qualifying farmers’ skills, and establishment of agricultural cooperative societies.

Globally, economies have become complex and new technologies have transformed and facilitated the modernization of economies. In the previous literature, economic complexity approach has become one of the popular tools in the development and innovation studies of economic geography. Researchers have found that green technology and eco-innovation approaches should be used to decisively reduce the effects of carbon emission on the environment. However, debates about the impact of economic complexity on environment remain unsettled since some emerging production technologies have far-reaching pollution effects. This study explored the impacts of economic complexity on environmental sustainability in Turkey using the novel Fourier-based approaches, namely: Fourier Augmented Dickey-Fuller (FADF) and Fourier autoregressive-distributed lag (FARDL) models. The Fourier-based approaches indicated that all variables (economic complexity index (ECI), GDP, energy consumption, and CO₂ emission (CO₂E)) are cointegrated in the long run. Additionally, the FARDL model implied that (i) in the long run, the effect of ECI (as a proxy for economic complexity), GDP (as a proxy for economic growth), and energy consumption on CO₂E (as a proxy for environmental quality) is important; (ii) economic complexity decreases environmental degradation in Turkey; and (iii) economic growth and energy consumption negatively affect environmental quality. The results also showed that economic complexity could be used as a policy tool to tackle environmental degradation. The findings also revealed that the fossil fuel-based economy will continue to expand and undermine Turkey's efforts to meet its net zero emission target by 2053. Therefore, policy-makers should take actions and establish diversified economic, environmental, and energ strategies. For policy insights, the Turkish governments can use the combination of tax exemptions and technical support systems to support knowledge creation and the diffusion of environmentally friendly technologies The governments can also impose strict environmental regulations on the knowledge development phases.

Agroforestry can leverage the co-benefits of climate change adaptation and mitigation while conserving biodiversity and restoring degraded and deforested lands. The preference of relevant stakeholders regarding agroforestry practices enhances sustainable land management through strategic decision-making in Seychelles and other island states. A suitable approach for assessing stakeholders’ preferences of agroforestry is the implementation of the strengths, weaknesses, opportunities, and threats (SWOT) approach in combination with the analytic hierarchy process (AHP) method. The entry point of this study is an extensive literature review process, during which 28 SWOT factors were identified. These SWOT factors were deliberated on during a half-day workshop with agricultural experts who agreed on 20 SWOT factors that reflect the local realities of the Seychelles through a consensus approach. Using the SWOT-AHP approach, focus group discussions were conducted to examine the perceptions of researchers and extension workers about the adoption of agroforestry in Seychelles. The results indicated that the positive aspects of smallholder agroforestry outweigh the negative aspects. For example, increased agricultural production, control runoff and soil erosion receive the highest scores among the strength factors perceived by researchers and extension workers, respectively. The willingness of international organizations to fund agroforestry-related projects and the existence of native tree species on farmlands have the highest scores among the opportunity factors. The lack of education, information, and communication between the government and farmers, and the small land size and crop competition have the highest scores among the weakness factors. Lastly, change in government policies on land use has the highest score among the threat factors by researchers, whereas the most significant threat is climate change and variability for the extension workers. The provision for a thirty-year land lease agreement in the National Agroforestry Policy of Seychelles is viewed by both groups as an incentive that could potentially drive the adoption and acceptability of agroforestry. Furthermore, better coordination of various efforts to promote agroforestry and more substantial extension services for farmers, especially the role of technologies for optimal production on small plots of land, can enhance climate resilience in Seychelles and other small island developing states.

The relationship between environmental degradation and poverty has increasingly become the focus of national strategic decision-making in recent years. However, despite several theoretical explorations on the nexus, a dearth of empirical literature on the poverty-environmental degradation nexus, specifically on Sub-Saharan Africa (SSA), still exists. In this study, we investigated the poverty-environmental degradation nexus in SSA. We hypothesized that poverty is both a cause and effect of environmental degradation, and this relationship is explained as a vicious cycle. Unlike previous studies, we employed several alternative indicators of environmental degradation to examine the poverty-environmental degradation nexus in this study. We used data from 41 countries of SSA between 1996 and 2019 and employed the generalized method of moments (GMM) approach. The findings suggest a cyclical relationship between poverty and environmental degradation in SSA, which confirms that an increase in poverty leads to an increase in environmental degradation, especially in deforestation and PM2.5 emissions. Similarly, the increase in environmental degradation positively affects poverty in SSA. We also confirmed that exogenous conditioning factors such as population growth rate, education, industrialization, and income inequality, institutional quality indicators such as governance effectiveness, control of corruption, freedom ad civil liberty, and democracy, and endogenous factors including fossil fuel energy use, fuelwood energy use, household health expenditure, infant mortality rate, and agriculture productivity influence the nexus between poverty and environmental degradation. The findings on the relationship between poverty and environmental degradation in SSA are a testimonial evidence that both poverty and environmental degradation are significant issues in SSA. Hence, poverty alleviation policies in SSA should not lead to PM2.5 emissions and deforestation, which may as well force people into a poverty-environmental degradation trap. Instead, poverty reduction policies should simultaneously achieve environmental conservation.

The escalating conflict between human and wildlife due to competing demands for limited space and resources has raised concerns worldwide, and understanding the dynamics of this conflict is crucial for devising effective strategies and policies. The present study is an attempt to carry out a bibliometric analysis of the published literature on the topic of human-wildlife conflict (HWC) for the period of January 1991–February 2023. For carrying out the analysis of the data obtained from Web of Science, the ‘Bibliometrix’ tool, developed through the R programming language, was used. The findings of the study revealed that a total of 1592 documents have been published on the HWC research topic from January 1991 to February 2023 within 338 sources. It is observed that the number of publications has continuously increased since 1991, with an annual growth rate of 5.16%. A total of 4995 authors have contributed to the targeted research field. Of the 388 sources, the journal ‘Biological Conservation’ is the most relevant and productive, followed by ‘Oryx’ and ‘Human Dimensions of Wildlife’. Based on the country production analysis, authors from 110 countries have contributed to the field, and the USA has the highest frequency of publications on HWC, followed by the UK and Australia. The USA also has the highest multiple country publications and has collaborated with 88 countries, with the highest frequency of collaboration with the UK, followed by India, Australia, and South Africa. The most frequently used keywords include ‘human-wildlife conflict’, ‘conservation’, ‘conflict’, ‘human-wildlife’, ‘wildlife’, ‘wildlife management’, ‘livestock’, ‘management’, ‘coexistence’, and ‘carnivore’. The present study identifies the most prolific authors, sources, institutions, and countries, as well as the study hotspots in the subject of HWC, which may assist researchers in finding the best working and publication platforms. Further, it may also help them identify reliable research partners to acquire the best findings and develop more effective strategies and policies to address the issue.
