On September 6th, 24 Kilo Ravi, a tribal representative, submitted a formal appeal to the District Collector of Alluri Sitarama Raju (ASR) District, a newly established district carved from the erstwhile Visakhapatnam District. The appeal was made on behalf of particularly vulnerable tribal families residing in Suddagaruvu, a village within the Vanjaari Gram Panchayat of G. Madugula Mandal.
In his representation, Ravi emphasized that the community has relied on a local spring as its primary drinking water source for nearly four decades. However, in recent years, the spring has dried up during the summer months, and the water becomes contaminated with mud during the rainy season, rendering it unsafe for consumption. This situation has posed significant challenges, particularly for children and the elderly, who have suffered from health issues due to the lack of access to clean drinking water.
Ravi urged the authorities to address this critical issue by either tapping nearby hill streams using gravitational force or installing a bore well to ensure a reliable supply of safe drinking water for the families.
The tribal communities in the former tribal districts of Srikakulam, Vizianagaram, Visakhapatnam, and East and West Godavari are heavily reliant on forest resources for their livelihoods. Their economic and cultural practices are deeply intertwined with the forests, which serve as a vital source of sustenance. According to the Indian Forest Survey Report 2021, these tribal districts experienced a net loss of 372 square kilometers of forest cover between 2019 and 2021, affecting both the Reserve Forest Area and the Green Wash area. This decline in forest resources presents significant challenges to the well-being and economic stability of these communities.
Impact of climate change on natural resources
Climate change is one of the most pressing global challenges of our time, with far-reaching consequences for ecosystems, natural resources, and human societies. The direct impacts on land, forests, and water resources are particularly concerning, as these are fundamental to both ecological stability and human livelihoods.
This analysis explores how climate change-induced factors, such as altered precipitation patterns and rising temperatures, are exacerbating environmental degradation. Additionally, the cascading effects on biodiversity, migration, and traditional knowledge systems in general are examined to illustrate the interconnectedness of climate change with socio-economic issues.
Impact on land
One of the most immediate and visible consequences of climate change is the disruption of precipitation patterns, which leads to land degradation. Erratic and intense rainfall events, increasingly common due to global warming, accelerate soil erosion, deplete nutrients, and reduce soil fertility. These effects are particularly damaging to shallow-root crops like millets, which are highly sensitive to changes in soil quality. Consequently, agricultural productivity declines, threatening food security and farmer livelihoods.
The increase in surface runoff, particularly in sloped or deforested regions, exacerbates these challenges. When heavy rains strip away topsoil, the land's ability to retain moisture is diminished, placing additional stress on irrigation systems.
Over time, this degradation reduces the agricultural viability of the land, forcing communities to overexploit the remaining fertile areas. Practices such as overgrazing and the abandonment of non-viable plots, coupled with increased competition for arable land, further strain local ecosystems.
For instance, the scheduled area of the Rampachodavaram division in ASR District, traditionally known for receiving an average rainfall of 1,275 mm, has experienced significant fluctuations due to climate variability. Rainfall surged to 1,537 mm in 2010-2011 but dropped drastically to 969 mm in 2011-2012. In subsequent years, rainfall continued to fluctuate, increasing from 1,017 mm in 2015-2016 to 1,266 mm in 2016-2017, and peaking at 1,694 mm in 2022-2023.
Despite these trends, the extent of cultivated land has varied greatly between seasons, with more land being utilized during Kharif (the monsoon season) compared to Rabi (the dry season). In 2022-2023, for example, 67,512 acres were cultivated during Kharif, while only 35,918 acres were cultivated during Rabi, out of a total of 97,299 acres of cultivable land. This disparity highlights the continued dependency of agricultural productivity on erratic rainfall, despite improvements in land management practices.
Another critical issue exacerbated by climate change is desertification, driven by higher evaporation rates and prolonged droughts. Reduced soil moisture and the desiccation of organic matter hinder seed germination and decrease plant survival rates. As desertification progresses, arable lands shrink, exacerbating food insecurity and threatening the livelihoods of rural communities dependent on agriculture.
Impact on forests
Forests are highly sensitive to climate change, with rising temperatures and extreme weather events posing significant risks to their ecosystems. Prolonged droughts weaken trees, making them more susceptible to diseases and pests, while higher temperatures increase the likelihood of forest fires. These fires are particularly destructive to young saplings, hindering forest regeneration and reducing biodiversity.
Increased rainfall and storm intensity further destabilize forest ecosystems. Heavy rain, combined with strong winds, can uproot trees and trigger landslides, destroying large tracts of forest. Waterlogging caused by prolonged periods of rain contributes to root rot, weakening trees and disrupting the natural growth cycles of various plant species. When trees fail to flower or bear fruit as expected, the broader food web is affected, leading to cascading effects on biodiversity.
The Kakinada forest division, in the erstwhile East Godavari District, which encompasses much of the tribal areas of the Rampachodavaram Division, experienced a significant loss of forest cover. In 2007-2008, the division lost 829 hectares of forest, while in 2011-2012, the loss amounted to 422 hectares. This continued depletion of forest resources poses a serious threat to the livelihoods and environmental sustainability of the region's tribal communities.
Additionally, desertification and deforestation, driven by both human activity and climate change, contribute to the proliferation of invasive species that are more resilient to climate variability. These invasive species often replace native flora, reducing overall biodiversity.
The loss of forest ecosystems not only diminishes carbon sequestration but also negatively impacts communities that depend on forests for essential resources such as food, medicine, and building materials. Over time, the degradation of forests contributes to increased poverty, particularly in areas where forest resources are critical to local economies.
Impact on water resources
Water resources, perhaps the most essential of all natural assets, are severely affected by climate change. Altered rainfall patterns, intense storms, and prolonged droughts disrupt water recharge processes and deplete groundwater reserves. In deforested or sloped regions, rapid surface runoff causes siltation in streams, and reservoirs, further degrading water quality and threatening aquatic ecosystems.
Increased evaporation rates due to rising temperatures further reduce the availability of freshwater for agricultural, domestic, and industrial use. As water levels in rivers, lakes, and reservoirs decrease, pollutants become more concentrated, reducing the quality of drinking water and endangering public health. Traditional water sources, such as tanks, springs, and streams, are drying up, leaving communities with limited access to potable water.
For example, during the period from 2011 to 2012, when rainfall decreased significantly, 606 minor irrigation works were undertaken in the scheduled area of the Rampachodavaram division to combat soil erosion and enhance water conservation efforts.
However, by 2016-2017, the number of such projects had dropped to just 20, and no irrigation works were implemented in 2022-2023, despite increasing rainfall levels. This sharp decline in water management initiatives demonstrates the region's growing vulnerability to both land degradation and water scarcity.
The disruption of water flow patterns also has a profound impact on aquatic biodiversity. Changes in water levels and flow rates alter habitats and life cycles, leading to the decline of fish populations and other aquatic species. This, in turn, affects traditional fishing communities and agricultural sectors reliant on consistent water supplies, contributing to economic instability and increased competition for diminishing resources.
Impact of climate change on communities
While the direct effects of climate change on natural resources are severe, the indirect consequences on human communities are equally profound. Vulnerable populations, particularly those dependent on agriculture, forests, and fisheries, are disproportionately affected. The loss of livelihoods, food insecurity, migration, and the erosion of traditional knowledge systems are all significant socio-economic challenges exacerbated by climate change.
Loss of livelihoods and food insecurity
As natural resources deteriorate, communities dependent on agriculture, forestry, and fishing experience reduced income and heightened food insecurity. The depletion of forest products such as fruits, nuts, medicinal plants, and building materials directly impacts livelihoods, particularly for women and children, who often rely on these resources for subsistence. Reduced agricultural productivity due to poor soil conditions and water scarcity further exacerbates poverty and increases the risk of malnutrition in vulnerable populations.
In areas where biodiversity is critical to local diets, the decline of forest and marine ecosystems has a direct impact on food security. As traditional sources of income and food disappear, economic instability deepens, leaving affected communities with few alternatives. Social inequalities are further magnified as marginalized groups face greater barriers to adapting to changing environmental conditions.
Displacement and migration
The degradation of natural resources forces many communities to migrate in search of better living conditions, often to urban areas where they face a host of new challenges. Environmental migration leads to the fragmentation of traditional social structures, the erosion of cultural practices, and a weakening of governance systems in displaced communities. Migrants often experience social exclusion, poor living conditions, sexual exploitation, harassment at work place and also limited access to essential services in overcrowded urban environments.
Tribal communities, whose livelihoods are closely tied to their land and natural resources, are particularly affected by environmental displacement. The spiritual and cultural connections these communities maintain with their environment are severed, further weakening their resilience to climate-induced changes.
Erosion of traditional knowledge
Traditional knowledge, passed down through generations, has played a crucial role in the sustainable management of natural resources. However, rapid environmental changes driven by climate change are undermining the effectiveness of this knowledge.
The older generations may find that their deep understanding of local ecosystems no longer holds relevance in the face of changing conditions, leading to knowledge gaps between generations. This disconnect hampers the ability of communities to adapt to the new realities imposed by climate change.
As landscapes evolve due to environmental pressures, the cultural significance of sacred sites and natural landmarks is also diminishing. Communities are becoming increasingly disconnected from their heritage, resulting in the loss of not only ecological knowledge but also the spiritual connections that have sustained them for generations.
Health impacts
The effects of climate change and environmental degradation are having profound implications on public health. The decline in water quality, primarily due to the contamination of water sources, is leading to an increase in waterborne diseases such as dysentery and typhoid fever. Concurrently, changing climate conditions are fueling a rise in vector-borne diseases like malaria and dengue.
Moreover, reduced agricultural productivity is contributing to food and nutrition insecurity, disproportionately affecting vulnerable groups, including children and the elderly. Many regions, particularly those isolated geographically, face significant barriers to accessing adequate healthcare, and existing infrastructure is often insufficient to meet the growing needs of affected populations.
The loss of herbal plants, traditionally used for medicinal purposes, adds another layer of complexity to the health challenges faced by these communities. These climate-induced changes, compounded by the loss of livelihoods and displacement, are placing significant stress on mental health, leading to an increase in anxiety and other mental health issues among affected populations.
Conflict over resources
The escalating pressures of climate change and environmental degradation are intensifying competition for diminishing natural resources, such as water and forests. As a result, conflicts are increasingly arising within tribal communities, as well as between tribal groups and government agencies, external entities, including non-tribal populations, over land and resource rights.
These conflicts exacerbate existing social and economic inequalities, particularly among marginalized communities. Governance structures are coming under increased strain as disputes over resources weaken traditional authority, destabilizing community cohesion. This combination of resource scarcity, inequality, and governance challenges presents significant risks to the stability and well-being of these communities.
Vulnerability of tribal areas
Tribal communities remain deeply dependent on local ecosystems for essential resources such as food, water, medicine, and shelter. However, climate change poses an existential threat to the unique biodiversity in these areas, endangering local flora and fauna, and disrupting the tribal economies and cultural practices that are intricately tied to nature.
The remote locations of many tribal areas exacerbate these challenges, limiting their access to climate adaptation resources and external support. Economic marginalization further compounds the vulnerability of these communities, as limited economic opportunities leave them more exposed to the adverse effects of climate change. As a result, traditional lifestyles, social structures, and cultural practices are increasingly at risk, placing the future of these communities in jeopardy.
Conclusion
The challenges posed by climate change to natural resources and tribal communities are immense and interconnected. As climate-induced changes in land, forests, and water resources ripple through ecosystems and tribal societies, the need for comprehensive and adaptive strategies becomes increasingly clear.
Efforts to mitigate the impacts of climate change must prioritize both the preservation of natural resources and the protection of rights of vulnerable communities that rely on these resources for their livelihoods, cultural identity, and spiritual well-being.
Building resilience in the face of climate change requires a multifaceted approach, including sustainable land management, reforestation, water conservation, and the revitalization of traditional knowledge systems. Coordinated action at all levels is essential to address the dual challenges of environmental degradation and socio-economic vulnerability. Such efforts will help to ensure a more sustainable future for both natural ecosystems and the communities that depend on them.
