Pastoralists in the Modern World and India




Pastoralists in the Modern World 


Nomads are people who do not live in one place but move from one area to another to earn their living along with their herds of cattle, goat,sheep, camels,yak,etc. in search of pasture. 


Pastoralism is a form of animal husbandry where domesticated animals are raised and bred primarily for the purpose of producing meat, milk, hides, wool, and other animal products. It is practiced in various forms around the world, particularly in regions where agriculture is less feasible. Here are some key characteristics of pastoralism:

Key Characteristics

  1. Mobility:

    • Transhumance: Seasonal movement of herds between fixed summer and winter pastures.

    • Nomadism: More irregular and often longer-range movement patterns, with no permanent home, as herders move in search of pasture and water.

  2. Animal-Centric:

    • The primary focus is on the care, breeding, and management of livestock such as cattle, sheep, goats, camels, yaks, reindeer, and horses.

    • Livestock are the main source of livelihood, providing food (meat and milk), clothing (wool and hides), and other products.

  3. Adaptation to Environment:

    • Pastoralists often inhabit marginal lands unsuitable for crop farming, such as deserts, grasslands, and mountainous regions.

    • They have developed knowledge and skills to manage and utilize scarce resources efficiently.

  4. Social Structure:

    • Pastoral societies often have a hierarchical social structure, with clan or family units being the basic social unit.

    • Leadership and decision-making may be based on age, experience, and knowledge of livestock management.

  5. Economy:

    • The economy is primarily based on livestock and their products. Trade and barter are common, with livestock often used as a form of currency or wealth.

    • Some pastoralists engage in supplementary activities like small-scale farming, hunting, or gathering.

  6. Cultural Practices:

    • Rich traditions and cultural practices are centered around livestock, including rituals, festivals, and folklore.

    • Knowledge of animal behavior, breeding, and pasture management is passed down through generations.

  7. Land Use:

    • Pastoralism relies on communal land use, with shared grazing rights and practices to manage and rotate pasture use.

    • Land tenure systems vary, but there is often a strong emphasis on collective management and stewardship of resources.

  8. Resilience and Adaptation:

    • Pastoralists have developed strategies to cope with environmental variability and extreme conditions, such as droughts, floods, and harsh winters.

    • They often maintain diverse herds to spread risk and ensure sustainability.

Types of Pastoralism

  1. Nomadic Pastoralism:

    • Characterized by continuous movement of herders and their livestock in search of fresh pastures.

    • Common in arid and semi-arid regions such as the Sahara Desert, the Sahel, and parts of Central Asia.

  2. Semi-Nomadic Pastoralism:

    • Involves periodic movement between fixed or semi-fixed locations.

    • Practiced in regions where environmental conditions require seasonal migration.

  3. Transhumance:

    • Seasonal migration between specific summer and winter pastures.

    • Often practiced in mountainous regions where herders move livestock to high-altitude pastures in summer and lower altitudes in winter.

  4. Agro-Pastoralism:

    • Combines livestock rearing with crop farming.

    • Practiced in regions where both livestock and crop production are viable, allowing for a more diversified livelihood.

Challenges Faced by Pastoralists

  1. Environmental Changes:

    • Climate change and environmental degradation threaten traditional grazing lands and water sources.

    • Increased frequency of droughts, floods, and extreme weather events can disrupt traditional pastoral practices.

  2. Land Rights and Access:

    • Encroachment of agricultural expansion, urbanization, and land privatization can limit access to traditional grazing lands.

    • Conflicts over land use and access to resources are common in many pastoral regions.

  3. Economic Pressures:

    • Market fluctuations, competition with commercial livestock farming, and limited access to markets can impact the economic viability of pastoralism.

    • Livestock diseases and lack of veterinary services pose significant challenges.

  4. Social and Cultural Changes:

    • Modernization, education, and migration of younger generations to urban areas can lead to cultural erosion and loss of traditional knowledge.

    • Policies and development initiatives may not always align with the needs and practices of pastoral communities.

  5. Political and Legal Issues:

    • Pastoralists may face marginalization and lack of political representation.

    • Legal frameworks and policies may not adequately protect their land rights and traditional practices.

 In 1871, the colonial government in India passed the Criminal Tribes Act. By this Act many communities of craftsmen, traders and pastoralists were classified as Criminal Tribes. They were stated to be criminal by nature and birth. Once this Act came into force, these communities were expected to live only in notified village settlements. The pastoral wasteland rules taken their pasture to agriculture, to earn revenues and taxes, 

When grazing lands were taken over and turned into cultivated fields, the available area of pastureland declined. Similarly, the reservation of forests meant that shepherds and cattle herders could no longer freely pasture their cattle in the forests. As pasturelands disappeared under these pressure.

Efforts to Support Pastoralism

  1. Sustainable Management:

    • Promoting sustainable land management practices to ensure the long-term viability of pastoral systems.

    • Integrating traditional knowledge with modern science to improve pasture management and livestock health.

  2. Policy and Advocacy:

    • Developing policies that recognize and support the rights of pastoralists, including land tenure and access to resources.

    • Advocacy efforts to raise awareness and ensure the inclusion of pastoralists in decision-making processes.

  3. Economic and Social Support:

    • Providing access to markets, credit, and veterinary services to enhance the economic resilience of pastoral communities.

    • Supporting education and capacity-building initiatives to empower pastoralists and preserve their cultural heritage.

Pastoralism is a dynamic and resilient way of life that has adapted to some of the world's most challenging environments. Ensuring its sustainability requires a nuanced understanding of its complexities and a commitment to supporting the rights and livelihoods of pastoral communities.

 Major nomadic pastoral tribes of India:

  1. Gujjar bakarwals of jammu and kashmir : in summer dry scrub forest of high mountains while in winters moves to low hills of siwaliks along with their sheep and goat.

  2.  Gaddi shepherds of Himachal Pradesh had a similar cycle of seasonal movement. They too spent their winter in the low hills of Siwalik range, grazing their flocks in scrub forests. By April they moved north and spent the summer in Lahul and Spiti.

  3. The gujjar of kumaon and gharwal of uttarakhand  are  cattle herders came down to the dry forests of the bhabar in the winter, and went up to the high meadows – the bugyals – in summer.

  4. This pattern of cyclical movement between summer and winter pastures was typical of many pastoral communities of the Himalayas, including the Bhotiyas, Sherpas and Kinnauris. All of them had to adjust to seasonal changes and make effective use of available pastures in different places. When the pasture was exhausted or unusable in one place they moved their herds and flock to new areas. This continuous movement also allowed the pastures to recover; it prevented their overuse.

  5. Raika camels grazing on the Thar desert in western Rajasthan. Only camels can survive on the dry and thorny bushes that can be found here; but to get enough feed they have to graze over a very extensive area. the Raikas combined cultivation with pastoralism. During the monsoons, the Raikas of Barmer, Jaisalmer, Jodhpur and Bikaner stayed in their home villages, where pasture was available. By October, when these grazing grounds were dry and exhausted, they moved out in search of other pasture and water, and returned again during the next monsoon. One group of Raikas – known as the Maru (desert) Raikas – herded camels and another group reared sheep and goat.

  6. Dhangars were an important pastoral community of Maharashtra they move between konkan(winters) and semi-arid areas of central plateau of Maharashtra during the monsoon (grow bajra). They keep sheep and buffalos.

  7. The Gollas herded cattle. The Kurumas and Kurubas reared sheep and goats and sold woven blankets lives in karnataka and andhra pradesh between dry areas of interior plateau and wet coastal areas in monsoon and non monsoon season.

  8. Banjaras were yet another well-known group of graziers. They were to be found in the villages of Uttar Pradesh, Punjab, Rajasthan, Madhya Pradesh and Maharashtra. In search of good pastureland for their cattle, they moved over long distances, selling plough cattle and other goods to villagers in exchange for grain and fodder

  9. Maldhari herders moving in search of pastures. Their villages are in the Rann of Kutch.

Sea Level Rise Causes, Impacts, and Solution


The sea, a vast and powerful force, has captivated humanity for millennia. But our planet's oceans are not static; they are in a constant state of flux. Sea level, the average height of the ocean's surface, has risen and fallen throughout Earth's history, leaving its mark on the land and its inhabitants. Understanding these changes is crucial, for they hold the key to our planet's past and future. Sea level changes can be global, affecting coastlines worldwide, or local, impacting specific regions. A rise in sea level can reshape continents, inundate low-lying areas, and alter ecosystems. Conversely, a fall can expose land bridges, create new coastal plains, and trigger shifts in plant and animal life. Throughout geological time, sea levels have fluctuated dramatically. During glacial periods, vast ice sheets locked up enormous volumes of water, causing sea levels to plummet. Conversely, interglacial periods, like the one we are currently experiencing, witness the melting of these ice sheets, leading to a rise in sea levels. These natural fluctuations have shaped our planet for millions of years. However, the rate of sea level rise we are witnessing today is unprecedented in human history. This rapid change is primarily driven by human activities, making it imperative to understand its causes and consequences. causes : The IPCC projections include estimates of contributions from: Ocean thermal expansion Glacier mass loss Greenland and Antarctic ice sheet surface mass balance (net change from the addition of mass through precipitation and loss through melting) and dynamic processes such as collapse of ice shelves Changes in land water storage (dams and ground water storage) Impact of sea level rise : coastal flooding intensity and frequency is increasing , earlier it was 1 in every 100 years now 1 in every 10 years. land size is decreasing due to sea level rise ; low-lying coastal areas are submerged; coral islands are (average height is 5 m or below) , will be lost if this rise of sea level continues . already many islands are being lost. submerged landforms : rias, fiords/fjords, submerged valleys, parallel islands to the coast (darmintia coast of croatia). some densely populated coastal cities are on threat of submergence and lost such as jakarta, manilla, Guangzhou, mumbai,etc-- coastal soils and water bodies are becoming saline. coral reef ecosystem : threats and challenges in the forms of coral bleaching, coral deaths, microfossil planktons such as foraminifera and diatoms sinking Higher projected storm surge and inundation levels. Landward recession or erosion of sandy shorelines. Depending on the rate and scale of sea level rise, the environmental, social and economic consequences or shoreline recession within low lying inter-tidal areas, in particular, may be significant in the medium to long term. Salt water intrusion and landward advance of tidal limits within estuaries. This may have significant implications in the medium to long term for freshwater and salt water ecosystems and development margins, particularly building structures and foundation systems within close proximity to the shoreline. Existing coastal gravity drainage, stormwater infrastructure and sewerage systems may become compromised over time as mean sea level rises. Sea level rise will influence the entrance opening regimes for intermittently closed and open lakes and lagoons and alter catchment flood behaviour over time. The level of protection provided by seawalls and other hard engineering structures will decrease over time due to increasing threat form larger storm surges and inundation at higher projected water levels. according to the study by 2100, the global population potentially exposed to episodic coastal flooding will increase from 128 -171 million to 176-287 million. the value of global assets exposed to these episodes is projected to be between $6000-$9000 billion, 12-20 %of the global GDP. GLOBALLY, 68% area that is prone to coastal flooding over 32% can be attributed to regional sea level rise by 2100. mitigation and adaptation measures against sea level rise :-- Hierarchy of Adaptation Options Avoid the risk. Identify future ‘no build areas’ and use planning tools to prevent new development in areas at risk now or in the future. Undertake a planned or managed retreat from the risk. Withdraw, relocate or abandon assets that are at risk and allow ecosystems to retreat landward as sea levels rise. Accommodate for the risk. Continue to use the land but accommodate changes by building in piles growing salt tolerant crops or converting from agriculture to aquaculture. Protect from the risk. Use hard structure (sea walls) or soft solutions (dunes and vegetation) to protect land from the sea.

Carbon Farming The Future of Sustainable future


Carbon Farming: 


• Carbon farming integrates the fundamental role of carbon in life processes with agricultural practices, focusing on regenerative techniques that enhance ecosystem health, improve soil health, and boost agricultural productivity. 

• This approach helps mitigate climate change by increasing carbon storage in soil and reducing greenhouse gas emissions.

 • It is adaptable to various agro-climatic conditions and offers solutions to issues like soil degradation, water scarcity, and climate variability. 

• The technical term for this is carbon sequestration.


Soil organic carbon is a problem to Indian soil :--

================================

Soil organic carbon in Indian soil fall’s to 0.3% from 1% in last 70 years. Soil carbon maintain the fertility, water retain ability, structure and microbes growth. Due to decrease in soil carbon agriculture production and productivity is falling.


According to CSE report recently 85% soil samples are deficient in soil carbon 


Causes :

1) intensive farming practices (removal of carbon from soil)

2) decreasing compost and green manuring (poor recharge of carbon into the soil)

3) excessive use of chemical fertilisers and pesticides 


Impact:

1) declining agriculture production and productivity 

2) poor growth of microorganisms in the soil

3) food crisis and farmer distress 


Measures:

1) use of bio fertilisers and compost

2) micro irrigation facilities improvement 

3) crop diversification


 Carbon farming techniques: 

• Carbon farming employs various sustainable agricultural practices to enhance carbon sequestration, improve soil health, and reduce greenhouse gas emissions.

 • Techniques such as rotational grazing, agroforestry, conservation agriculture, and integrated nutrient management each contribute differently. 

o Agroforestry (including silvopasture and alley cropping) increases carbon storage in vegetation, while conservation agriculture reduces soil disturbance and increases organic content. 

o Integrated nutrient management optimizes the use of organic fertilizers to promote soil fertility and reduce emissions. 

o Additionally, strategies in livestock management help lower methane emissions and enhance carbon storage in pastures.

 • Collectively, these practices not only contribute to mitigating climate change but also support diverse and resilient agricultural ecosystems.


 Challenges:

 • Carbon farming offers significant benefits but faces several challenges that affect its effectiveness, including geographical variations, soil types, crop selection, water availability, biodiversity, and the scale of farming operations.

 • Its success is also dependent on effective land management, supportive policies, and active community involvement. 

• Regions with long growing seasons, ample rainfall, and good irrigation systems are more conducive to carbon farming due to better conditions for vegetation growth and carbon sequestration.

 • Techniques like agroforestry and conservation agriculture have high potential in such fertile and well-watered areas. • Conversely, carbon farming is more challenging in arid regions with limited water availability, where water is prioritized for essential uses over agricultural expansion. 

• This scarcity can limit plant growth, essential for carbon sequestration through photosynthesis. • Additionally, the choice of plant species is critical, as not all are equally effective at trapping and storing carbon, and some may not thrive in dry conditions.

 • Economic factors also play a role, particularly in developing countries where small-scale farmers may lack the resources to implement sustainable practices without financial support. 


Global scenario:

 • Carbon farming has gained traction worldwide with schemes such as carbon trading in the agriculture sector, particularly in countries like the U.S., Australia, New Zealand, and Canada where voluntary carbon markets are prominent.

 • Examples include the Chicago Climate Exchange and Australia’s Carbon Farming Initiative, which encourage practices like no-till farming and reforestation to reduce carbon emissions and enhance carbon sequestration in agriculture. 

• Internationally, projects like Kenya’s Agricultural Carbon Project, supported by the World Bank, demonstrate carbon farming’s potential to address climate change mitigation, adaptation, and food security in developing regions.

 • Additionally, the ‘4 per 1000’ initiative launched during the COP21 climate talks in 2015 in Paris emphasizes the critical role of carbon sinks in mitigating greenhouse gas emissions. 


Indian scenario:

 • Organic and agro-ecological farming practices have demonstrated the potential to sequester carbon, with the possibility of creating an economic value of approximately $63 billion across India's 170 million hectares of arable land. 

 • This includes incentives for farmers, offering them about ₹5,000-6,000 per acre annually for providing climate services through sustainable agriculture. 

• Regions like the Indo-Gangetic plains and the Deccan Plateau are well positioned for carbon farming, whereas the Himalayan and coastal areas face challenges due to their terrain and salinisation, respectively.

 • Additionally, implementing carbon credit systems could provide farmers with supplementary income by monetizing the environmental services of carbon sequestration. 

• Research suggests that agricultural soils could absorb 3-8 billion tonnes of CO2 equivalent annually over 20-30 years, significantly aiding in climate stabilization and bridging the gap in necessary emissions reductions.

 • However, scaling up carbon farming in India requires overcoming hurdles such as limited awareness, insufficient policy frameworks, technological limitations, and creating an environment conducive to adoption.

 • Despite these challenges, promoting carbon farming aligns with India's interests to combat climate change, enhance soil health, boost biodiversity, and generate economic benefits for farmers.
