Green Criminology in the Niger Delta of Nigeria: Why African Women’s Voices Matter

Oil spills in resource-rich areas in Africa have led to irreversible environmental degradation, resulting in social conflicts that have greatly affected women. Yet, the experiences of ordinary women affected by resource extraction activities in the Global South are often marginalised. Recent calls for the southernising of criminology are gaining momentum and could be linked to calls for rethinking how knowledge about Africa is produced, including in its gendered dimensions. For example, in what ways do women’s voices matter on issues related to the environment in the Niger Delta? And how do their voices intersect with green criminological theories? This article focuses on amplifying affected women’s lived experiences in the resource-rich area of the Niger Delta of Nigeria. Using data collected between 2019 and 2022 through participatory video, focus group discussions, and in-depth interviews, the paper underscores the need to give women a voice on matters that affect the environment, and peace and war dynamics.

Assessing decarbonization: a comparison of the green sacrifice ratio for China and India

ABSTRACT Carbon mitigation and net-zero targets have an important place on the political agenda for all countries. Countries have been seeking to decouple economic growth and carbon emissions to achieve decarbonization. However, there is a cost of the decarbonization of economies, which can be called as Green Sacrifice Ratio (GSR), and this is critical for developing countries because they have been in the growing stage. By considering the critical role of GSR in achieving net-zero emissions by decarbonizing economies, the study comparatively examines how much environmental quality should be sacrificed for per capita economic growth in China and India. In line with this purpose, the study uses the Fourier-Shin cointegration test and various time series estimators with Fourier approximations for the period from 1989/Q1 to 2022/Q4. Estimation results are as follows: (i) all variables follow the non-stationary process, (ii) the long-run relationship exists between variables, and (iii) Estimation results show that GSR is 0.65% for China and 0.78% for India. Therefore, China and India sacrifice a significant amount of environmental quality for a 1% increase in per capita income level. Also, the ecological cost of increasing economic welfare in India is higher with regard to China. Besides, the results are robust according to the alternative method. Thus, the study recommends that both Chinese and Indian policymakers should revise the economic expansion structure with green growth strategies to prevent irreversible environmental degradation due to higher economic growth.

Comprehensive chemical passivation of active-state heavy metals in relation to soil biological activity in Taojia River basin

Rapid global industrialization has resulted in irreversible environmental degradation, with one pressing issue being the escalating problem of land contamination induced by heavy metals (HMs). This phenomenon not only inflicts lasting harm on plants and microorganisms within the affected regions but also imposes significant losses on various industrial chains, particularly in the realm of agriculture. A noteworthy illustration is the soil contamination in the Taojia River Basin, Hunan Province, China, attributed to mining activities. Therefore, this study is dedicated to examining the passivation of active-state lead (Pb) and cadmium (Cd) in the cultivated fields of the Taojia River Basin. To achieve this, two passivating agents, namely bentonite (referred to as passivator-P) and an acidifying soil agent known as “Shi Di Jia” (referred to as passivator-S), were employed, along with a control group (CK). The passivation of Pb primarily relies on cation exchange adsorbed on the passivator's surface, while the passivation of Cd is intricately linked to total nitrogen content (TN). Indoor incubation tests were conducted to assess Pb and Cd in the soil. Additionally, an analysis of various soil health indicators and their relationships with microbial dynamics and soil enzymes was undertaken. The findings revealed that passivator-P exhibited greater efficacy in the passivation of Pb at concentrations of 3% and 5%, while higher concentrations of passivator-S demonstrated increased effectiveness in passivating Cd. Concerning bacterial diversity, the soil pH post-passivation showed a positive correlation with the Observed_species index, whereas Pb and Cd exhibited negative associations with the Chao1 index. Regarding fungal diversity, soil TN post-passivation displayed a positive correlation with the Simpson index. It is concluded that adding passivator-P at a 3% concentration proved to be the optimal passivating agent for Pb-contaminated soils in the Taojia River Basin. Although passivator-S demonstrated lesser efficacy in passivating Pb, it proved to be suitable for Cd passivation. These findings offer a crucial reference for passivation passivation remediation in the Taojia River area and other sites with similar characteristics, shedding light on the impacts on soil organisms. The implications underscore the necessity for site-specific remediation strategies and a holistic approach to addressing HMs contamination.

Efficiency evaluation for urban industrial metabolism through the methodologies of emergy analysis and dynamic network stochastic block model

Frequent economic activities in cities have exacerbated irreversible environmental degradation. It is urgent to balance the relationship between economic growth, resource investment and environmental protection. With the concept of urban metabolism, this study attempts to clarify the internal structure of urban system metabolism and the metabolic relationship between specific economic sectors. And then, it determines the metabolic level of current urban industrial development by means of metabolic efficiency evaluation, which can help more accurately reveal the sustainability of urban metabolic activities. Based on them, this study proposes a metabolic efficiency evaluation model combined with emergy analysis and slack-based measure dynamic network Data Envelopment Analysis (DEA). Through the multi-period and multi-stage network DEA model, the internal structure of urban industrial metabolism is opened. And considerring industrial waste as an undesirable carryover will be regarded as additional inputs in future period to reflect the impact on industrial metabolic efficiency. Using the proposed model, the industrial metabolic efficiency of 18 first-tier cities in China from 2016 to 2020 was analyzed. It is found that all cities are inefficient, which indicates that all evaluated cities need to make appropriate adjustments to improve their weak stages. In response to the specific problems of inefficiency in each city, an improvement framework is proposed to help each city better realize the sustainable development of the urban economy.

Assessing the effect of soil testing on chemical fertilizer use intensity: An empirical analysis of phosphorus fertilizer demand by Irish dairy farmers

Phosphorus (P) is considered the second most important nutrient for grass growth following nitrogen (N) and it is applied on grasslands mainly through chemical fertilizers. Irrational use of chemical fertilizers, however, lead to severe and often irreversible environmental degradation, which has, consecutively, an impact on the overall sustainability of the world. Farmers are responsible for the amount of P fertilization on their farm, and despite the efforts to design policies to assist them with precise chemical fertilizer use, chemical P use is still high, particularly on pasture fields where grass needs to be constantly maintained. . In Ireland, where agriculture is majorly pasture based, soil testing is highly recommended, as part of the Irish rural development plans, in order to encourage efficient nutrient management. This study uses an econometric model on data from the Irish national farm survey to examine the examines the relation between soil testing and chemical P fertilization in Irish pasture based farm systems. Results indicate the soil-testing leads to the use lower amounts of chemical fertilizers, which is also correlated with landscape characteristics and farm intensity, indicating the need for targeted management approaches to farm level management decision making.

Estimation of Potential Soil Erosion and Sediment Yield: A Case Study of the Transboundary Chenab River Catchment

Near real-time estimation of soil loss from river catchments is crucial for minimizing environmental degradation of complex river basins. The Chenab river is one of the most complex river basins of the world and is facing severe soil loss due to extreme hydrometeorological conditions, unpredictable hydrologic response, and complex orography. Resultantly, huge soil erosion and sediment yield (SY) not only cause irreversible environmental degradation in the Chenab river catchment but also deteriorate the downstream water resources. In this study, potential soil erosion (PSE) is estimated from the transboundary Chenab river catchment using the Revised Universal Soil Loss Equation (RUSLE), coupled with remote sensing (RS) and geographic information system (GIS). Land Use of the European Space Agency (ESA), Climate Hazards Group InfraRed Precipitation with Station (CHIRPS) data, and world soil map of Food and Agriculture Organization (FAO)/The United Nations Educational, Scientific and Cultural Organization were incorporated into the study. The SY was estimated on monthly, quarterly, seasonal, and annual time-scales using sediment delivery ratio (SDR) estimated through the area, slope, and curve number (CN)-based approaches. The 30-year average PSE from the Chenab river catchment was estimated as 177.8, 61.5, 310.3, 39.5, 26.9, 47.1, and 99.1 tons/ha for annual, rabi, kharif, fall, winter, spring, and summer time scales, respectively. The 30-year average annual SY from the Chenab river catchment was estimated as 4.086, 6.163, and 7.502 million tons based on area, slope, and CN approaches. The time series trends analysis of SY indicated an increase of 0.0895, 0.1387, and 0.1698 million tons per year for area, slope, and CN-based approaches, respectively. It is recommended that the areas, except for slight erosion intensity, should be focused on framing strategies for control and mitigation of soil erosion in the Chenab river catchment.

Sustainability accounting of neighborhood metabolism and its applications for urban renewal based on emergy analysis and SBM-DEA

Rapid urbanization exacerbates urban metabolic activities associated with irreversible environmental degradation. Evaluating urban metabolic performance is an effective method to meet targets for sustainable development in contemporary urban areas. Neighborhoods, which are regarded as the basic parts of cities, can detail the metabolic structure and interactions from a bottom-up perspective. In consequence, this study proposed an eco-efficiency model which combined emergy synthesis and slack-based measure data envelopment analysis. A case study with questionnaire and statistical data for eight communities in Chongqing, China was used to shed a light on the properties of emergy metabolic flows and eco-efficiency. The results showed that the study communities heavily depended on external resources. Intense communal activities within relatively small geographic areas caused immediate surroundings to suffer from enhanced environmental pressures. Eco-efficiency performances were mostly invalid, and a significant heterogeneity existed among communities. Enhancing the performance of renewable and non-renewable resources whilst also reducing the production of wastes was essential to improve the overall eco-efficiency of local communities. To assist with this, a neighbor-level sustainable renewal framework was proposed which took account of metabolic flows and communal renewal operations. The findings of this study can provide a paradigmatic example for urban renewal projects elsewhere that embed metabolic performance in neighborhood redevelopment.

Fluvial incision caused irreversible environmental degradation of an ancient city in the Mu Us Desert, China

AbstractAncient cities are excellent spatiotemporal indicators for the study of historical human activities and environmental change. The ancient city of Sanchahe is located at the southern margin of the Mu Us Desert, China. It is an ideal location for studying the complex relationships between historical desertification and human activities. Field observations of the ancient city walls, a well, and a spring, as well as 14C dating, grain size, spatial analysis of archaeological sites, and analyses of historical seismicity, indicated that neotectonics may have contributed to crustal uplift and accelerated fluvial incision of the Wuding River. This rapid incision caused a decline in groundwater levels, which is an important reason for the irreversible environmental degradation around Sanchahe city over the past 800 yr. This study provides new evidence for such environmental degradation and may contribute to a better understanding of historical desertification in the Mu Us Desert.

From black box to glocalised player? Corporate personality in the twenty-first century and the scope of law’s regulatory reach

This article seeks to investigate the evolving notion of corporate personality from the nineteenth century to the present and the scope for the regulatory effect of law thereon especially in terms of the ongoing management of the relationship between the economic and the social spheres. Utilising the work of the economic historian Karl Polanyi on the rise of the self-regulating market in the nineteenth century, it will suggest that the most appropriate image underlying the dominant legal conception of the company in the twentieth century was that of a black box by which the company was largely isolated from its broader social and political environment as a result of the complex interaction of legal and economic discourses surrounding the emergence of a distinct market-based economic sphere. In the light of the current financial crisis, and even more pertinently against the backdrop of the risk of potentially irreversible environmental degradation, many of the fundamentals of the market-based economic paradigm are presently being called into question. Accordingly, it will be argued, drawing upon Polanyi’s notion of the double movement read in the light of Ulrich Beck’s account of reflexive modernity, that the black box model of the company is increasingly perceived as inappropriate for the twenty-first century and that to attain greater institutional legitimacy there is pressure for the legal conception of corporate personality to be reconfigured as that of a glocalised player open to its environment. The article will conclude by examining the scope of law’s regulatory power to construct such a holistic corporate personality capable of commanding such institutional legitimacy, with particular reference to the significance of s. 172 Companies Act 2006.

Effect of oil spills on infant mortality in Nigeria

Oil spills can lead to irreversible environmental degradation and are a potential hazard to human health. We study how onshore oil spills affect neonatal and infant mortality by combining spatial data from the Nigerian Oil Spill Monitor with Demographic and Health Surveys. To identify a causal effect, we compare siblings born to the same mother, conceived before and after a nearby oil spill. We find that nearby oil spills that occur before conception increase neonatal mortality by 38.3 deaths per 1,000 live births, which corresponds to an increase of around 100% on the sample mean. The effect is fairly uniform across girls and boys, socio-economic backgrounds, and locations. We show that this effect is not driven by events related to oil production or violent conflict. Rather, our results are consistent with medical and epidemiological evidence showing that exposure to hydrocarbons can pose risks to fetal development. We provide further evidence suggesting that the effects of oil spills on neonatal mortality persist for several years after the occurrence of an oil spill.

The Effect of Oil Spills on Infant Mortality: Evidence from Nigeria

Oil spills can lead to irreversible environmental degradation and pose hazards to human health. We are the first to study the causal effects of onshore oil spills on neonatal and infant mortality rates. We use spatial data from the Nigerian Oil Spill Monitor and the Demographic and Health Surveys, and rely on the comparison of siblings conceived before and after nearby oil spills. We find that nearby oil spills double the neonatal mortality rate. These effects are fairly uniform across locations and socio-economic backgrounds. We also provide some evidence for negative health effects of nearby oil spills on surviving children.

Bright spots: seeds of a good Anthropocene

The scale, rate, and intensity of humans’ environmental impact has engendered broad discussion about how to find plausible pathways of development that hold the most promise for fostering a better future in the Anthropocene. However, the dominance of dystopian visions of irreversible environmental degradation and societal collapse, along with overly optimistic utopias and business‐as‐usual scenarios that lack insight and innovation, frustrate progress. Here, we present a novel approach to thinking about the future that builds on experiences drawn from a diversity of practices, worldviews, values, and regions that could accelerate the adoption of pathways to transformative change (change that goes beyond incremental improvements). Using an analysis of 100 initiatives, or “seeds of a good Anthropocene”, we find that emphasizing hopeful elements of existing practice offers the opportunity to: (1) understand the values and features that constitute a good Anthropocene, (2) determine the processes that lead to the emergence and growth of initiatives that fundamentally change human–environmental relationships, and (3) generate creative, bottom‐up scenarios that feature well‐articulated pathways toward a more positive future.

Mining and/or tourism development for job creation and sustainability in Dullstroom, Mpumalanga

Although the tourism sector has greater potential for job creation than the mining sector, the debate on which sector may be more sustainable for employment and local social development, has not been extensively researched, especially in the global South. The popular tourist destination of Dullstroom, Mpumalanga has come under threat from an increase in the number of mining applications for coal (and diamonds). Despite opposition to mining from civil society due to the potential destruction of the natural environment and hence tourism job losses, mining applications are being approved by the ruling party in the country. Government and mining companies state that mining will contribute to much needed job creation and social development. Disparity thus exists between mining and tourism development frameworks for sustainable job creation. This research thus presents perspectives from key participants surrounding the sustainability of mining and/or tourism jobs in Dullstroom, including the benefits and challenges for job creation and sustainability offered by both sectors. Investigations reveal that mining should not be allowed in pristine areas such as Dullstroom’s wetlands, biodiversity and conservation and agricultural lands. Besides the short-term jobs offered by mining, the precautionary principle, as suggested in South African regulations, should apply against mining development since there are added threats of serious or irreversible environmental degradation which does not support sustainable tourism development and long-term jobs. However tourism in Dullstroom is also beset with challenges which need to be addressed if tourism is to contribute to sustainable employment for the majority of people.

Multi-Decadal Mangrove Forest Change Detection and Prediction in Honduras, Central America, with Landsat Imagery and a Markov Chain Model

Mangrove forests play an important role in providing ecological and socioeconomic services for human society. Coastal development, which converts mangrove forests to other land uses, has often ignored the services that mangrove may provide, leading to irreversible environmental degradation. Monitoring the spatiotemporal distribution of mangrove forests is thus critical for natural resources management of mangrove ecosystems. This study investigates spatiotemporal changes in Honduran mangrove forests using Landsat imagery during the periods 1985–1996, 1996–2002, and 2002–2013. The future trend of mangrove forest changes was projected by a Markov chain model to support decision-making for coastal management. The remote sensing data were processed through three main steps: (1) data pre-processing to correct geometric errors between the Landsat imageries and to perform reflectance normalization; (2) image classification with the unsupervised Otsu’s method and change detection; and (3) mangrove change projection using a Markov chain model. Validation of the unsupervised Otsu’s method was made by comparing the classification results with the ground reference data in 2002, which yielded satisfactory agreement with an overall accuracy of 91.1% and Kappa coefficient of 0.82. When examining mangrove changes from 1985 to 2013, approximately 11.9% of the mangrove forests were transformed to other land uses, especially shrimp farming, while little effort (3.9%) was applied for mangrove rehabilitation during this 28-year period. Changes in the extent of mangrove forests were further projected until 2020, indicating that the area of mangrove forests could be continuously reduced by 1,200 ha from 2013 (approximately 36,700 ha) to 2020 (approximately 35,500 ha). Institutional interventions should be taken for sustainable management of mangrove ecosystems in this coastal region.

Environmental poverty, a decomposed environmental Kuznets curve, and alternatives: Sustainability lessons from China

Amid increasing recognition of the importance of the environmental factor in understanding poverty and development, this article coins the term “environmental poverty” to refer to the lack of the healthy environment needed for society's survival and development as a direct result of human-induced environmental degradation. A decomposed environmental Kuznets curve (EKC) demonstrates that places (such as countries, counties, or cities) following the “grow first, clean up later” approach (or the first half of the EKC) may obtain economic gains accompanied by extreme environmental sacrifice, excessive social injustice, and income and environmental inequalities. The same place may include communities whose curves differ in shape. Some communities may prosper at the expense of other communities, which may fall into environmental poverty and eventually irreversible environmental degradation and economic failure. Places following alternatives or “flat EKCs” may be slow in getting out of economic poverty, but enjoy a healthier environment, equality in income and environmental quality, and social justice. Countries, especially developing countries, should aspire to sustainable alternatives.

Repositioning Malta as a cultural heritage destination

PurposeThis paper aims to examine how Malta seeks to reposition itself as a “cultural heritage” tourist destination. After pursuing an expansion in its tourist industry in the 1970s, by the 1990s a sense of crisis prevails, due to the realization that irreversible environmental degradation is damaging the islands with regard to both the cultural heritage and ecological environment. This case study of Malta focuses on the conditions that prompt a policy of environmental intervention. The paper shows how a policy of change results from three main factors: pressures brought from various stakeholders, the availability of funding, and a sense that failure to act will have serious detrimental consequences.Design/methodology/approachThe paper gives an account of recent historical background to explain the case of Malta's tourism. Governmental policy documents, press articles, promotional tourist literature, interviews with experts, and relevant stakeholders in the cultural and educational sphere form the basis for the authors' interpretation.FindingsGovernmental policy of investment in the environment is subject to resistance to change due to inertia, the costs of intervention and opposition from entrenched business interests. The role of opinion leaders, pressure groups and of volunteer‐run environmental NGOs is critical in exerting pressure on the government to adopt a policy of intervention to safeguard the environment and heritage as well as providing expertise and constituting agencies to whom the government can entrust the implementation of environmental projects.Originality/valueThe case of Malta as a small nation state offers indications that are not easily transferable but which shows the role of different stakeholders in the implementation of a policy of change.
