Abstract:

         The advent of globalization, particularly following India’s economic liberalization in 1991, has presented a complex and often contradictory set of challenges and opportunities for the nation’s environmental governance. This paper examines India’s evolving role in environmental protection in this transformative period. It argues that globalization has acted as a dual-edged sword, concurrently accelerating environmental degradation through rapid industrialization and consumerism, while also providing access to green technologies, international finance, and a platform for global environmental diplomacy. The paper analyses the trajectory of India’s domestic environmental policy, highlighting the critical role of judicial activism and the strengthening of legal and institutional frameworks, such as the National Green Tribunal. It further explores India’s transition on the international stage from a cautious participant to a proactive leader, exemplified by its instrumental role in the Paris Agreement and the launch of initiatives like the International Solar Alliance (ISA). Despite these advancements, significant challenges persist, including a persistent gap between policy formulation and implementation, the contentious development-versus-environment debate, and acute vulnerability to climate change. The paper concludes that India’s future role is pivotal; its ability to successfully navigate the intricate nexus of economic growth and ecological sustainability will not only determine its own developmental trajectory but also have profound implications for global environmental security.

Introduction:

           The process of globalization, characterized by the accelerated integration of economies, cultures, and societies, has fundamentally reshaped the global environmental landscape. For developing nations, this integration has been a catalyst for unprecedented economic growth, but it has often come at a significant ecological cost¹. India, since its economic liberalization in 1991, stands as a prime case study of this complex dynamic. As one of the world’s fastest-growing major economies and its most populous nation, India’s developmental pathway and its approach to environmental stewardship carry immense global weight. The post-globalization era has forced India to confront a dual reality: the pressures of resource-intensive growth and pollution on one hand, and the opportunities for international collaboration and technological advancement in sustainability on the other².

           Before 1991, India’s environmentalism was largely shaped by domestic concerns, culminating in foundational legislation like the Water (Prevention and Control of Pollution) Act, 1974, the Air (Prevention and Control of Pollution) Act, 1981, and the comprehensive Environment (Protection) Act, 1986, which was enacted in the aftermath of the Bhopal gas tragedy³. However, the post-1991 economic reforms unshackled the industrial sector, attracted Foreign Direct Investment (FDI), and integrated India into global supply chains. This unleashed economic forces that placed immense strain on the country’s natural resource base and its nascent regulatory capacity.

          Now, it is essential to examine India’s evolving role in environmental protection since 1991. It reveals that India’s journey has been one of adaptation and transformation, characterized by a reactive strengthening of domestic policy in response to escalating environmental crises and a gradual, yet decisive, shift towards a leadership role in global environmental diplomacy. This paper analysed the dual impacts—negative and positive—of globalization on India’s environment. It will then trace the evolution of the nation’s domestic legal and institutional frameworks, with a special focus on the crucial role of judicial activism. Subsequently, India’s engagement in international environmental forums is discussed. The persistent challenges and future prospects for sustainable development in India are also analysed.

The Dual Impact of Globalization on India’s Environment

         Globalization’s effect on India’s environment is not monolithic; it has simultaneously been a source of degradation and a catalyst for positive change.

A. Negative Externalities and Accelerated Degradation

          The most visible consequence of economic liberalization was the rapid pace of industrialization and urbanization. The drive to attract investment and boost manufacturing output often led to the relaxation of environmental oversight, creating “pollution havens” in certain industrial clusters⁴. This resulted in:

1. Increased Pollution: Air and water pollution levels surged. The proliferation of thermal power plants, vehicular emissions in rapidly growing cities, and untreated industrial effluents from sectors like textiles, tanneries, and chemicals have led to a severe public health crisis. A 2020 report noted that 22 of the world’s 30 most polluted cities were in India, with Particulate Matter (PM2.5) concentrations far exceeding World Health Organization (WHO) guidelines⁵.
2. Resource Depletion: The demands of a globalized economy have intensified pressure on India’s natural resources. Deforestation for mining, infrastructure projects, and industrial agriculture has accelerated. Water tables have plummeted due to unsustainable extraction for both agriculture and industry, leading to acute water stress in many parts of the country⁶.
3. Consumption Patterns and Waste Management: Globalization introduced global brands and fostered a culture of consumerism. This, coupled with rapid urbanization, has led to a monumental increase in municipal solid waste, plastic waste, and electronic waste (e-waste). The infrastructure for managing this waste has failed to keep pace, resulting in overflowing landfills, polluted water bodies, and informal, hazardous recycling practices⁷.

B. Positive Opportunities and Catalysts for Change

           Despite these severe negative impacts, globalization has also provided pathways for environmental improvement.

1. Access to Green Technology and Finance: Integration with the global economy has facilitated the transfer of cleaner and more efficient technologies. India has become one of the world’s largest markets for renewable energy, driven by falling costs of solar panels and wind turbines, largely imported or produced with foreign technology. Furthermore, international financial mechanisms, such as the Green Climate Fund and FDI in sustainable projects, have provided crucial capital for India’s green transition⁸.
2. Enhanced Global Awareness and Civil Society: Globalization has connected Indian environmental movements with international networks. This has amplified the voices of non-governmental organizations (NGOs) and civil society groups, enabling them to exert greater pressure on the government and corporations. Global norms and standards regarding environmental protection and corporate social responsibility have slowly begun to influence domestic policy and corporate behavior⁹.
3. Pressure from International Markets: As Indian companies became more integrated into global supply chains, they faced increasing pressure from international buyers and consumers to adhere to higher environmental and labour standards. This has incentivized some export-oriented industries to adopt cleaner production processes and obtain international certifications like ISO 14001.

The Evolution of Domestic Environmental Governance

         In response to the escalating environmental crises of the post-globalization era, India’s domestic governance framework underwent a significant, albeit often reactive, evolution, driven primarily by judicial intervention and subsequent legislative action.

(i) The Era of Judicial Activism

           Perhaps the most significant development in Indian environmental jurisprudence has been the proactive role of the judiciary. Through Public Interest Litigations (PILs), the Supreme Court of India and various High Courts have expanded the interpretation of the Constitution to protect the environment. The court declared that the “Right to Life” under Article 21 of the Constitution includes the right to a clean and healthy environment¹⁰. This principle became the basis for numerous landmark judgments:

• In the M.C. Mehta v. Union of India series of cases, the Supreme Court issued directives on controlling pollution in the Ganga River, relocating polluting industries from Delhi, and mandating the use of Compressed Natural Gas (CNG) for public transport in the capital¹¹.
• The judiciary established key environmental principles in Indian law, including the “precautionary principle,” the “polluter pays principle,” and the doctrine of “public trust,” which holds that the state is a trustee of natural resources for the public¹².

           This judicial activism filled a critical void left by executive and legislative inertia, compelling the government to act on pressing environmental issues.

(ii) Strengthening of Institutional and Legal Frameworks

           Prompted by judicial orders and growing public pressure, the government strengthened its institutional architecture.

1. The National Green Tribunal (NGT): A landmark development was the establishment of the National Green Tribunal in 2010. The NGT is a specialized judicial body equipped with expertise to handle environmental cases effectively and expeditiously. It has delivered several impactful judgments, including bans on old diesel vehicles, regulations on sand mining, and penalties for environmental violations, establishing itself as a powerful environmental watchdog¹³.
2. New Policies and Regulations: The post-globalization era saw the introduction of a new suite of environmental regulations targeting specific problems. These include the E-Waste (Management) Rules, 2016; Plastic Waste Management Rules, 2016; and Solid Waste Management Rules, 2016. The National Environment Policy (2006) was formulated to mainstream environmental concerns into all development activities¹⁴.
3. Environmental Impact Assessment (EIA): The EIA notification, first issued in 1994 and subsequently amended, made environmental clearance mandatory for a wide range of development projects. However, the EIA process has been a subject of intense debate, with critics arguing that recent amendments, such as the draft EIA Notification 2020, have sought to dilute environmental safeguards in favor of promoting “ease of doing business”¹⁵.

India on the Global Stage: International Environmental Diplomacy

            India’s role in international environmental negotiations has transformed significantly. Initially, its stance was defensive, strongly advocating for the principle of “Common But Differentiated Responsibilities and Respective Capabilities” (CBDR-RC) to emphasize the historical responsibility of developed nations for climate change and to protect its own “right to develop”¹⁶. While this principle remains a cornerstone of its foreign policy, India’s approach has become more proactive and solution-oriented.

A. Leadership in Climate Action: The Paris Agreement

         At the 2015 Paris Climate Conference (COP21), India played a crucial role as a bridge between developed and developing nations, helping to forge the final consensus. It submitted ambitious Nationally Determined Contributions (NDCs), which included:

• Reducing the emissions intensity of its GDP by 33-35% by 2030 from 2005 levels.
• Achieving about 40% of cumulative electric power installed capacity from non-fossil fuel-based energy resources by 2030.
• Creating an additional carbon sink of 2.5 to 3 billion tonnes of CO2 equivalent through additional forest and tree cover by 2030.

           At COP26 in Glasgow (2021), India further enhanced these commitments, pledging to achieve net-zero emissions by 2070 and setting a target of 500 GW of non-fossil fuel energy capacity by 2030¹⁷.

B. Proactive Multilateral Initiatives

           Beyond its commitments, India has launched major international initiatives, positioning itself as a leader of the Global South in the green transition.

1. International Solar Alliance (ISA): Co-founded by India and France in 2015, the ISA is a treaty-based intergovernmental organization that aims to mobilize technology and finance to promote the widespread deployment of solar energy. With over 120 signatory countries, the ISA is a testament to India’s vision of “one sun, one world, one grid” and its leadership in climate solutions¹⁸.
2. Coalition for Disaster Resilient Infrastructure (CDRI): Launched by India at the 2019 UN Climate Action Summit, the CDRI is a multi-stakeholder global partnership that aims to promote the resilience of new and existing infrastructure systems to climate and disaster risks. This initiative addresses a critical adaptation need for developing countries¹⁹.

These initiatives signal a strategic shift in India’s role from being a mere rule-    mntaker in global environmental governance to an active agenda-setter.

Challenges and Future Directions

           Despite significant progress in policy formulation and international diplomacy, India faces formidable challenges in translating its ambitions into on-the-ground reality.

1. The Implementation Gap: A chasm persists between India’s well-formulated environmental laws and their enforcement. State Pollution Control Boards (SPCBs) and other regulatory bodies are often underfunded, understaffed, and susceptible to political and corporate influence. This results in widespread non-compliance and continued environmental degradation²⁰.
2. Development vs. Environment Dichotomy: The tension between achieving rapid economic growth and ensuring environmental protection remains a central political challenge. The government has often been accused of prioritizing industrial and infrastructure projects by diluting environmental regulations, as seen in the controversies surrounding forest clearances and the EIA process.
3. Climate Change Vulnerability: India is one of the country’s most vulnerable to the impacts of climate change, including extreme weather events, sea-level rise, and water scarcity. Adapting to these impacts will require massive investment and planning, diverting resources that are also needed for mitigation and poverty alleviation²¹.
4. Resource Inefficiency and Circular Economy: India’s economy is still highly resource-intensive. Transitioning to a circular economy model, which emphasizes resource efficiency, recycling, and waste minimization, is crucial but remains in its nascent stages.

         In the future, India’s role will be defined by its ability to address these challenges. Key priorities must include strengthening regulatory institutions, investing in enforcement capacity, mainstreaming sustainability into economic planning, and fostering public participation in environmental decision-making.

Conclusion:

          The era of globalization has profoundly shaped India’s environmental trajectory, presenting it with a formidable set of problems and a unique array of opportunities. The pressures of a rapidly growing, market-integrated economy have undeniably exacerbated pollution, resource depletion, and ecological stress. However, this same period has seen the rise of a powerful and independent judiciary, the creation of a sophisticated legal framework, and the emergence of India as a credible and influential voice in global environmental diplomacy.

           India’s role is inherently paradoxical: it is a major contributor to global environmental challenges, yet it is also a source of innovative, large-scale solutions, particularly in the renewable energy sector. Its leadership through platforms like the ISA and CDRI demonstrates a clear intent to shape a more sustainable global future. The ultimate test, however, lies in its domestic performance. Bridging the gap between policy and practice, resolving the conflict between short-term economic gains and long-term ecological security, and building a truly sustainable development model are the defining challenges for India in the 21st century. The success or failure of this endeavour will not only determine the well-being of its 1.4 billion citizens but will also be a critical factor in humanity’s collective effort to secure a viable planetary future.

Abstract 

This study employed geospatial techniques to capture the process of land conversion taking place. The objectives include mapping the land use types. The methodology involved geospatial technique which uses remote sensing and GIS techniques to identify the past and current condition of land use change occasioned development activities in the Makurdi Metropolis for the period of 1999, 2009 and 2019. The result shows that overall, there was progressive and increasing change in built-up area and water body categories, at (17.00%) and (1.73%) respectively during the period of study. However, vegetation cover, farm land, bare land and wetland decreased by (2.51%), (3.51%), (4.61%) and (8.08%) respectively. Residential buildings are fast encroaching the flood plain of River Benue in Makurdi. There is a need to sensitize the residents on the danger of flooding and provisions should be made to relocate those already occupying the location.

1. Introduction

The population of the world is growing at different rates relative to the total population (Omali, 2020), and it is becoming more urbanized (Enoch, John, and Jonathan, 2020). Changes in land use and land cover (LULC), which are more common in developing countries, are a result of this population growth. Due to the “push” of rural areas and the “pull” of urban centers, Nigeria’s high rate of urbanization is changing its land use (Aluko, 2013). Unprecedented alterations in the ecosystem and environmental processes have, of course, been brought about by natural forces and human activity (Okeke and Omali, 2016). This has resulted in a decline in biodiversity and environmental degradation. Land use and cover change is a global phenomenon. While urban centers are growing in population and area the surrounding open/agricultural lands are rapidly changing. Construction is putting increasing pressure on the land use to make room for a variety of urban land uses. There are severe consequences from the ruthless reduction of available land per person, including low or decreased food production, ecological degradation, environmental problems, and socioeconomic difficulties.

Current methods for managing natural resources and keeping an eye on environmental changes heavily rely on studies on changes in land use and land cover (LULC) (Okeke and Omali, 2016). This makes it feasible to comprehend human interactions with natural resources, both past and present, as well as their effects. To get the desired outcome, the conventional approach to LULC assessment is inadequate (Okeke and Omali, 2018). Therefore, it’s critical to use cutting-edge technologies, such as sophisticated computers, remote sensing, geographic information systems (GIS), GPS, and the power of spatial information systems (Okeke and Omali, 2016). Since remote sensing is the only affordable technology that provides data on a global scale, it provides an important means of detecting and analyzing spatiotemporal dynamics on geographical entities (Omali, 2018a). Through the use of aerial or spaceborne sensors, remote sensing gathers data about Earth without requiring the sensors to come into direct physical contact with the target or object of interest (Omali, 2022a). According to Omali (2021) the electromagnetic radiation serves as the transmission medium for information. GIS is typically employed in the gathering, storing, modifying, analyzing, visualizing, and presenting of georeferenced data and information (Omali, 2022b). Through the manipulation, analysis, statistical application, and modeling of spatial data, it provides us with the ability to handle spatially referenced data (Omali, 2022c). In general, remote sensing data and GIS techniques have emerged as incredibly helpful tools for mapping natural resources, such as vegetation and changes in land use/cover over geographic areas. This has allowed for the removal of many of the constraints associated with traditional surveying techniques and the acquisition of a continuous and comprehensive ecosystem inventory. In light of this, research on the LULC in Makurdi was conducted using geospatial technologies over a 20-year period, from 2009 to 2019.

• Methodology
  • Data

Both primary and secondary sources provided data for the study; some of these are listed in Tables 1a and 1b. Satellite imagery and field observations make up the main sources. During the field campaign, training site coordinates were recorded using a handheld GPS device (Garmin Etrex 32). With the GPS using satellite, almost anywhere on Earth can be located at any time (Omali, 2023a). Furthermore, it is important to note that time-series data, such as remotely sensed data from various eras, must be applied in order to study and monitor LULC (Omali, 2023b). As a result, the time-series satellite data from three epochs of multi-spectral Landsat TM/ETM/OLI imagery were used in this study. Other materials such as newspapers, journals, textbooks, World Bank publications, and maps are included in the secondary sources.

      Table 1b: Satellite imageries used in the study

• Pre-processing of the Satellite Imagery

It is crucial to pre-process satellite images for accurate change detection (Andualem et al., 2018). Time series analysis requires this crucial step in order to reduce noise and improve the interpretability of image data (Yichun et al., 2008). The processes and methods used in satellite image processing include geometric correction, atmospheric and radiometric correction, and masking study areas. To produce a consistent and trustworthy image database, radiometric and atmospheric correction is applied to account for variations in the viewing geometry and instrument response characteristics, as well as atmospheric conditions related to scene illumination. Pre-processing techniques used in this study included study area masking, image enhancement, and correction for atmospheric and radiometric errors. In order to bring the image scene and the scanned topographic maps into the same coordinate system, they were also co-registered into UTM zone 32N, WGS 84.

• Image Classification

The goal of the imagery classification process was to assign each pixel in the digital image to one of many land cover classes, or “themes” (Omali, 2018b). This allows for the creation of thematic maps of the land cover present in an image. Finding the land use and land cover class of interest was the first stage in this study’s mapping and change analysis of land use and land cover. In this investigation, we employed six classes, as indicated in table 2, by incorporating and adapting the classification scheme from Andersen et al. (1971). The classes listed in Table 2 were utilized in this study. Also, the maximum likelihood supervised classification technique was used to classify LULC images from Landsat data. The study’s training sites were first located and defined. Fieldwork yielded training samples in line with Lu and Weng (2007). For the actual supervised classification of the study area, signature files containing statistical data about the reflectance values of the pixels within the training site for each of the LULC types or classes were developed in line Ojigi (2006). The supervised classification algorithm was imputed with the signatures.

• Land Use and Land Cover change Detection

There are numerous approaches for detecting changes in multi-spectral image data, such as time series analysis, vector analysis of spectral changes, and characteristic analysis of spectral type. Time series analysis is the most common method, and it was used in this study. Its objective is to analyze the course and trend of changes by tracking ground objects using continuous observation data from remote sensing (Adzandeh, et al., 2014). Naturally, post-classification comparisons can yield results of change that are acceptable and provide “from-to” data (Okeke and Omali, 2018).

• Results and Discussion
  • Land Use and Land Cover Classification Result

The satellite imageries covering the study area were classified in GIS environment. Tables 2 reveal that there is a progressive and significant increase in built-up area which is necessitated by the increase in commercial activities, residential growth, economic and social activities. This is in line with the findings of Etim and Dukiya (2013) who opine that urban encroachment on agricultural land has reduced the productivity of most farmers in Makurdi. The water body recorded little increase due to the increase in water works like construction of Kaptai Lake, which is the largest artificial lake in the country. The farm land, vegetation, bare land and wetland decreases throughout the period of study.

           Table 3: Land use and land cover distribution of Makurdi

The classified images (false colour composite) for the different periods 1999, 2009 and 2019 of study area are shown in Figures 5.1, 5.2 and 5.3 respectively. These colour composite shows the visual distribution pattern of the distribution and change taking place in the images of the areas throughout the period of study. The dominating land use and land cover category in 1999 as shown in Table 3 and figure 1 is the wetland covering an area of 214.89km² (26.22%). This is understandable as Hemba, et al. (2017) describes the relief of Makurdi town as lying entirely in the low- laying flood Plain with River Benue forming the major drainage channel. Farm land covers 203.56km² representing 24.83% of Makurdi.

                                        Figure 1: Land Use and Land Cover of Makurdi in 1999

 Most residents engage in farming, either crop production or livestock farming as the soil is fertile and the weather is conducive for agricultural practices. This assertion supports the views of Hula, (2010) who noted that most farmers in Makurdi cultivate land for crop production, rearing of animals for consumption and selling part of the produce to generate money to meet other needs. The populace of Makurdi comprises of indigenous farmers and migrants who are mostly engaged in farm activities as noted by Oju et al. (2011). Due to farming and hunting and other activities like sand mining carried out  in Makurdi, the size of bare land is observed to occupy large space of about 142.487km² represented by 17.38% in 1999. This is because farmers have enough space to cultivate. Farmers relocate to other lands whenever a particular land becomes unproductive and this has been the major cause of bare land in the study area. These contradicts Tee (2019) who argued that hunting, grazing  and other factors, which lead to clearing of land through manual, mechanical and chemical means have greatly changed the original vegetation cover to bare land and other classes of land use in Makurdi. The vegetation covered a reasonable size of land and it was 138.20km² (16.86%).This is attributed to the few number of settlers in Maukurdi and low level of human activities taking place within the urban centre as at the time. The water body was 22.459 km² (2.74%) with River Benue forming the major drainage system in the area and is the main source of water for human use. This is in line with the views of Nnule and Ujoh, (2017) who pointed out that Benue River is the main source of water in Makurdi. This doesn’t mean that other form of water sources like borehole, ponds and dams are not important.

Table 1 and figure 2 shows that the wetland had the largest area coverage of about 186.99km² (22.78%) in 2009 as the entire land fall within the Benue Valley and Trough. The geology of the study area influence the wetland, this infect is also confirmed by Iorliam, (2014). The farmland occupies 184.608km2 (22.52%), as most residents are farmers. The number is significant as civil

servants also own farms. The built-up, which was 170.968km² (20.86%) recorded a high increase due the increase in population. This corroborates the findings of Jiang, et al. (2013) which stated that the urban expansion on agricultural land is associated with both shrinking agricultural land area and a higher level of urban development. It also agrees with the findings of Araya and Cabral (2010) that substantial growth of urban areas has occurred worldwide in the last few decades with population increase being one of the most obvious agents responsible. The vegetation cover depreciated to 125.695km² (15.33%). This may be attributed to deforestation as more forest was cleared to provide more space for increasing human development. This is buttressed by Mugish and Nyandwi (2015) that housing development on arable farm land in most cities has become an issue on the global agenda in recent times. Bare land, which was 122.52km² (14.91%) decreased as the spaces were being covered with more structures but the water body 29.164km² (3.56%) slightly increased. Of course, this is an indication that most of the human activities use water and other sources of water are being developed to meet the need of the increasing populace.

The level of human activities in the year 2019 was very high, although Makurdi has no functional Master Plan to check the developmental activities, however, as shown in the image Fig5.3 and Table5.1, The built-up area of 237.46km2 (28.97%) in 2019 almost tripled its size recorded in 1999.This supports the assertion by United Nations Department of Economy and Social Affairs (UNDESA, 2010) that urban cities have changed from small isolated population

centres to large interconnected economic, physical, and environmental features. In recent time, issues of Herdsmen/Farmers crisis are among factors contributing to the migration of people from neighbouring villages to Makurdi Town for safety. These numbers of people who mostly settled along the urban hinterland, which is mostly used for agricultural purpose, have converted the land for building of houses and other socioeconomic infrastructures. The farm land occupies 174.735km² (21.32%) as it decreases with population upsurge settles in the study area. Farmers move outside of Makurdi to get land for their activities which make the cost of cultivation expensive than expected. Agencies with the mandate of protecting natural ecosystem are weak in areas of law enforcement in Makurdi as infrastructural developments are indiscriminately carried out. This observation contradicts the views of Wade quoted in Nico et al. (2000) that Various NGOs, government and international Agencies have been supporting the urban agriculture (UA) since 1970s in major world regions. There was reduction in wetland to 148.696km² (18.14%) and vegetation cover to 117.653km² (14.35%) compared to the previous ten years while the water body 36.658km²(4.47%) increases during the same periods.

• Conclusion

The research findings revealed that built-up area increased all through the period of study while arable land decreases due to infrastructural development. The rapid increase in built-up area is because the surrounding agricultural land is fast decreasing. Bare land, vegetation and wetland decreased throughout the period of study as human settlement increases over the years. Of course, it was observed that the effect of the development was concentrated more to the north eastern part of Makurdi as residential buildings with high rate of economic activities is observed in the region. Generally, this study has been able to show that conversion of open/agricultural land for infrastructural development was mostly due to increase in number of people through migration and natural means of population growth. The land use and land cover change detection for the period of 20 years revealed the extent and type of conversion. The study recommends Green areas within and around the city should be properly preserved as this allows for ventilation. All effort should be put in place to prevent unofficial development and measures should be in place to curb population growth which has encouraged urban sprawl on prime agricultural land as this is feasible around Makurdi hinterland.
