Bamboo for land restoration and income generation

Published

by Shantha Ramanayake

Bamboo is identified as a high priority crop for fast re-vegetating of bare lands because of its ability to grow in degraded soils and steep slopes where other plants do not successfully grow. It grows rapidly with minimum inputs and is endowed with an extensive underground network of rhizomes and roots that bind soil and store water. In addition to reclamation of degraded land, there is an added benefit as a commodity with high potential for income generation as the global bamboo market stands at over US $ 72 million and is expected to rise further.

Land degradation: Land degradation is an issue faced by many countries all over the world and has serious adverse effects on the environment and food security. It is a result of loss of biodiversity, soil erosion and depletion, soil pollution, water shortage and other factors. Land degradation is mainly induced by human activities apart from natural causes more prevalent now due to climate change. Agricultural and plantation soils have been continuously cultivated over many years focusing on increasing harvests without much concern on soil conservation and health. This has led to soil infertility and loss of production threatening food security. In addition, extensive areas of forests have been cleared with no regard to the environment. Such practices that bring about short term benefits have long term costs. According to the United Nations Convention to Combat Desertification (UNCCD) latest review (May 2021), 169 countries are affected by land degradation or drought and the average loss in production is reported to be about nine percent of the GDP. The worst affected are the central African countries where the total loss of production is estimated as a staggering 40 percent of the GDP. It would cost over 4.5 trillion dollars to take action now to halt this alarming trend. Thus there is much concern globally to rehabilitate degraded soils.

Sri Lanka is no exception. Although the country is endowed with natural resources which have sustained its people over a long period, these resources have deteriorated at an exponential rate over the last century. About 0.5% of forest land was converted to other land use types from 2000 to date. The plantation sector is affected considerably and some plantations have been abandoned. The productivity of 34% of the land area of the island is either declining or under stress and has led to increased poverty. The Government of Sri Lanka is a signatory to the UNCCD commitment to sustainable development goals and thus has a responsibility in preventing further land deterioration and is committed to restore degraded land.

Bamboo for land restoration: Among many other trees and crops identified for land restoration, a recently identified high priority crop is bamboo. Although the uses of bamboo are now well-known, information about success or failure in using bamboo for landscape restoration is limited. However, case studies in many countries show its feasibility.

Bamboo has been selected for fast re-vegetating bare land because of its ability with minimum inputs to grow in degraded soils and steep slopes where other plants fail to grow; it is also endowed with an extensive underground network of rhizomes and roots that bind soil and store water. This underground network is reported to extend up to 100 km per hectare in a bamboo plantation and grow to a depth of 60 cm and last many years. Even if the above ground biomass is destroyed the rhizome is able to regenerate fast.

Bamboo is the fastest growing plant on earth and a new culm emerging from the rhizome may grow up to one meter a day! For this reason bamboo can remove toxins and excess nitrogen from polluted soils and water ways fast. Bamboo sheds leaves during dry weather to conserve water and the leaf litter adds to soil carbon. Once a bamboo stand is established, surface run off during rains is minimized and water is stored in the soil and within the plant. Thus bamboo is able to re-vegetate and restore the productivity of unproductive land over a short period of time. Depending on the species, harvesting bamboo poles is possible three to six years after establishment and annually thereafter. Sustainable harvesting encourages fast growth in the following years. Most importantly the bamboo thus generated has an additional benefit as a commodity of high economic value.

Some case studies of land restoration by bamboo and recommendation to local situations: Bamboo planting programs need to be planned scientifically with due consideration for site – species matching, planting density, planting season etc. and management practices. Although much data is not available covering all these aspects, past experiences elsewhere could be considered.

A “Policy synthesis report, ‘Bamboo for Land Restoration’, FAO, INBAR, 2018” reported a few cases. A severely degraded land abandoned after brickmaking in Allahabad India, recovered remarkably after planting with bamboo. After 20 years the water table rose by 10 meters and it was possible to incorporate trees and other crops into this land as soil was enriched with 6-8 inches of humus by bamboo each year. Thus the farmers’ income increased. An added benefit was that they were able to get an additional income by selling bamboo poles to new industries that emerged in the vicinity. As a result of this success the project was scaled up to cover 100,000 hectares of degraded land in 600 villages in India.

In Chishui China bamboo plantations had 25 percent less water run off than an adjacent sweet potato farm and the bamboo plantation reduced soil erosion by 80%. A study in Ghana showed that Bambusa balcoa did not survive in an area with very low rainfall whereas Oxytenanthera abyssinica, a local species did better. In Colombia, planting Guadua bamboo reduced the compactness of soil making it more porous and improved water regulation and nutrient recycling. The farmers were able to increase their income by exploiting bamboo. In Nepal bamboo planting helped to reduce soil erosion and flood damage.

Considering our tea lands, over 150 years of tea cultivation has heavily degraded the soils and there is serious concern about a continuous decline of tea yields. Much of these lands will have to undergo long term rehabilitation with planting of perennial trees. Bamboo is ideal in this regard. There are many more abandoned and degraded lands as well as river and stream banks, boundaries of garbage dumps etc. which can be used to plant bamboo.

In order to succeed, the Government must take an interest and elevate the status of bamboo to a plantation crop with environmental, social and economic returns. Subsidies and supportive regulations will influence local participation to take the bamboo sector forward.

Benefits in planting bamboo: Woody bamboos are a valuable resource that can yield high socio-economic returns and environmental benefits. This is evident considering the global bamboo market which was valued at US$ 72 billion in 2019 and expected to rise at the rate of 5.5%. Bamboo has diverse applications but the rapid rise in bamboo industry was with the rediscovery of bamboo as a timber substitute minimizing the demand for valuable timber and pressure on forest resources. The bamboo industry is expected to rise continuously as the demand for sustainable green products are high.

Bamboo is utilized diversely ranging from high to medium and low technology applications. It is used in making timber substitutes such as bamboo paneling, mat board, plywood, veneer, strand woven bamboo, MDF board etc. These are used in making furniture and in buildings as flooring, paneling and even roofing. Manufacture of bamboo paper pulp can be carried out at a high tech industrial level and also as a cottage industry as happens in China. This is the oldest industrial application of bamboo which was started in India and China. Bamboo fibre in textile manufacture is a high tech industry. Canning of edible bamboo shoots has potential. Medium level industrial applications include manufacture of activated charcoal, biochar, bamboo mats, blinds, incense stick etc. while low level technologies include making handicrafts, charcoal and wood chips for use as fuel.

The situation in Sri Lanka: The first viable concept paper for establishing a bamboo industry in Sri Lanka was approved in 1992 and this was formulated after the tissue culture technique of mass propagating giant bamboo (Dendrocalamus giganteus) was developed by original research in the Institute of Fundamental Studies in Kandy. Its downstream application was the outcome of the Riverine Bamboo Project. This is presently under the purview of the Mahaweli Authority. The activities of the project were to initially establish a tissue culture laboratory and mass produce giant bamboo to be planted along the Mahweli and its tributaries with the objective of stabilizing the river bank and later to use the bamboo resource in industrial applications especially to make paper pulp.

The Mahaweli Authority claims that they have planted one million bamboo plants in riverbanks and catchment areas. It is reported that about 5,000 Ha of bamboo exist in Mahaweli catchment areas and forest reserves. Private sector has also established some bamboo but its extent not known. The tissue culture lab can mass produce planting stocks of valuable species of bamboo including Dendrocalamus hookeri, D. giganteus, D. asper, Bambusa vulgaris, B. ventricosa and others to supply palnting programmes.

The Industrial Technology Institute has carried out studies and developed the process of canning edible bamboo shoots and producing bamboo charcoal. This is the organization representing Sri Lanka in the International Network of Bamboo and Rattan (INBAR).

The UNIDO also had a bamboo project locally to promote the bamboo industry in making timber substitutes and identification of land for bamboo cultivation together with the Ministry of Industrial Development. They have established a Training Centre now under the Industrial Development Board.

The National Crafts Council promotes handicrafts and cottage industry has a training centre in Kuruwita.

Local market from available resources is limited to the following:

a. Blinds -for local and export markets

b. Handicraft – ships, pencil holders, vases, lamp sheds, tablemats

c. Incense sticks – machine made

d. Basket-ware, mats, furniture

e. Fresh edible shoots

f. Ornamental bamboo plants nurseries

g. Raw material: bamboo pole for construction/agriculture/ fisheries

h. Charcoal

Overall, the value of bamboo related product imports to Sri Lanka, grew by 40% from USD 0.5 Mn. in 2011 to USD 2 Mn. in 2015. Bamboo flooring accounted for nearly 60% of the total trade value of bamboo related imports in 2015.

The imported bamboo material/products are:

a. Flooring – imported, as a substitute for wood flooring

b. Yarn – imported from China for textile industry

c. Wood based panels – plywood, particle boards

d. Charcoal – export market is being developed

e. Canned edible shoots

f. Incense sticks – imported mostly from India, now banned

g. Bamboo sticks from China and Vietnam, importations, banned and relaxed

h. Many other home utility items – furniture, bamboo straws, ornaments,

Most of the imports could be produced in Sri Lanka, if the raw material and technology is available. The bamboo plantations should obtain Forest Stewardship Council certification (FSC) if they intend to export. With many countries establishing bamboo plantations, there is a demand to export bamboo tissue culture plants of ornamental or utility value. We have the potential of turning out bamboo charcoal on a sustainable basis to replace wood consumption and prevent deforestation.

Bamboo still remains an untapped avenue for economic growth in Sri Lanka although there are entrepreneurs showing interest. It is regretted that this country unlike many of her neighbors has hitherto hardly devoted attention to exploit the vast potential of bamboo. Government support is essential.

The Lanka Network of Bamboo and Rattan (SRINBAR) initiated in 2005 is now in the process of promoting cultivation of bamboo to cater to developing new industries and to network entrepreneurs involved or hoping to get involved in various aspects of bamboo. We are committed to taking the bamboo sector forward and hope many more will join us in this endeavor.

Door close to shutting on trying out Soft Power initiatives

Published

on

Prime Minister Narendra Modi with President Xi Jinping.IMAGE SOURCE : PTI/FILE

With the hopes of establishing a ceasefire in the Gaza now almost diminished and with Russia saying ‘No’ to an ‘immediate and full ceasefire’ in the Ukraine, the world now faces the spectre of stepped-up international disorder and lawlessness. It ought to be clear that, as matters stand, the exercising of Soft Power in international politics would prove exceptionally difficult.

In some respects the world is back to the power realities of the beginning of the 20th century that paved the way for the breaking out of the cataclysmic First World War. To state it briefly, uncurbed power aspirations accompanied by paranoid distrust and fear among the most powerful of states at the time precipitated the ‘great war’ that led to the perishing of countless lives.

Some of the principal states in the arena of world politics at the time were the Central Powers, comprising in the main, Germany, Austria- Hungary and the Ottoman Empire, while France, Russia and Great Britain constituted the Allies, or the principal states in the opposing camp. The US entered the war during the latter stages of the conflict on the side of the Allied powers that were essentially opposed to Germany’s perceived power expansion designs.

Briefly, aggravating mistrust and fear between the above camps led to the war’s outbreak. Some historians describe the war as a ‘tragedy of miscalculations’. The fear of the opposing camp was so great among these adversaries that they allowed themselves to be driven by emotion rather than reason. By misjudging each other’s motives and actions they triggered the war. Dialogue and Soft Power were to no avail.

While it is not this columnist’s contention that another World War is at hand, the inference is inescapable, given current developments in international politics, that the world could be perilously close to a situation where political leaders would be allowing themselves to be driven by emotion rather than reason.

For instance, the tremendous loss of civilian lives in the Gaza in particular and the Middle East in general is not preventing the US under President Donald Trump from fanatically backing the Netanyahu regime in the furtherance of its power ambitions. The relevant leaders on both sides of the Middle East divide could be described as having taken leave of their consciences, considering their indifference to the continuing bloodletting in the region.

The same goes for the Putin regime’s actions in the Ukraine. The continuing bloodshed on both sides of the divide in the latter theatre is apparently a matter of indifference to the leaders concerned. Once again, power and territorial ambitions are silencing consciences. Accordingly, in both situations under discussion unchecked emotion could sooner or later lead to large scale hostilities that could cut across regions.

The haplessness of the world in the face of the current disorder is compounded by the fact that the UN’s authority is going largely unrecognized by the relevant aggressor states. A question to be posed is whether the present international situation is parallel to that which presented itself in the run-up to World War Two, when the League of Nations proved totally incapable of reining-in the international hostilities that triggered the outbreak of war. If so, there is an urgent need for peace-loving sections the world over, including civilian publics, to urgently come together to address the grave risks confronting the world. The most pressing requirement is to give Soft Power or value-based politics a strong chance. Put simply, dialogue needs to be prized above discord.

Besides, it is important for those powers that could think and act with a measure of impartiality to come together to prevent the world from being further imperiled. Fortunately, India and China have decided to give cordial relations a try and this is a very promising development from the viewpoint of regional and global peace.

For example, Indian Prime Minister Narendra Modi in recent interviews with the international media has been quite elaborate on the need to ‘mend fences’ with China and introduce amity and harmony into Sino-Indian ties. Modi is on record that dialogue should be favoured over discord in China-India ties and that stronger inter-state cooperation is in the interests of the two neighbours and those of the international community.

It is interesting to note in this connection that Prime Minister Modi looked at China-India relations from a broad historical perspective as well. He said, among other things: ‘It has always been about learning from each other and understanding one another. At one time, Buddhism had a profound influence in China and that philosophy originated in India.’

This is the language of Soft Power or value-based politics that focuses on things that bring countries together rather than those which separate them. At the current juncture when discord is the state of the world, the language of Soft Power, or a focusing on values and ideals that cement ties among states, is what matters most.

Needless to say, we are today confronted with a dangerously polarized West. The US is on what could be called a hazardous foreign policy trajectory and Europe and Canada are closing ranks against it. There could be an increasing tendency among European states to emulate Germany and increase their defense spending, given that there is no possibility currently of bringing even a measure of peace to Ukraine, considering Russia’s recent decision to reject the US peace initiative. Accordingly, the West in particular would need to brace for times of stepped-up tension and discord.

India and China are two countries that the international community just could not ignore. Their heft in a multiplicity of fields is such that their persistent voices would be responded to positively by the rest of the world. A proactive engagement by these major Asian states in promoting global stability could induce the US and Russia, for instance, to quicken closures to the Ukraine and Middle East conflicts. Hopefully, China and India would be guided, going forward, by the greater good of the world community.

As for the rest of the global South, it too should explore the possibility of coming together once again for the sake of international amity and understanding. If the South is reading ‘the writing on the wall’ correctly it would perceive that it cannot neglect the obligation to join with major democracies, such as India, and dynamically champion the cause of world peace. Soft Power needs to be revived and kept going.

Gamini Dissanayake’s Cricketing Vision: The Foundation that Built Champions and the work that must continue

Published

on

Gamini

By Navin Dissanayake

Cricket has long been Sri Lanka’s greatest unifier. It is the sport that makes the world see us as more than just a small island—it makes them respect us, remember us, and recognise our strength.

But Sri Lanka’s rise in world cricket did not happen by accident. It was built on foundations laid decades ago, by leaders who saw the potential in our game long before we had the trophies to prove it.

One of those leaders was my father, Gamini Dissanayake.

On March 20th, we mark his birth anniversary, and as I reflect on his life, I realise that his greatest contribution to cricket was not just securing Sri Lanka’s Test status—it was creating the systems, infrastructure, and vision that allowed us to win the 1996 World Cup and stand tall on the international stage.

And now, as the Chairperson of the Sri Lanka Cricket Foundation, it is my responsibility to ensure that his vision is not just remembered, but carried forward.

Gamini Dissanayake: The Architect of Sri Lanka’s Cricketing Future

Many people know that my father fought for Sri Lanka’s Test status in 1981, but few realise that he also built the physical and structural foundations of our cricketing success.

✔ Sri Lanka Cricket Headquarters at SSC – When Sri Lanka gained Test status, we did not even have an administrative home for the sport. My father took the lead in establishing the Sri Lanka Cricket Board headquarters at the Sinhalese Sports Club (SSC) premises, ensuring that Sri Lanka’s cricket administration had a proper base from which to operate.

✔ Asgiriya Stadium Transformation – He believed that cricket should not be limited to Colombo. Under his leadership, the Asgiriya Stadium in Kandy was upgraded to international standards, becoming one of the most picturesque Test venues in the world and bringing world-class cricket to a new part of the country.

✔ Creating the Pathway for Future Champions – Infrastructure is not just about buildings; it’s about creating opportunities. He personally ensured that cricketing talent from all over Sri Lanka was recognised, leading to a more inclusive national team that truly represented the country.

His belief was simple—Sri Lanka should never be just another cricket-playing nation. We should be a force to be reckoned with.

The 1996 World Cup: A Dream That Started with His Vision

The greatest vindication of his efforts came fifteen years after he won Sri Lanka’s Test status—on March 17, 1996, when we defeated Australia to win the Cricket World Cup.

The players, the strategy, the talent, and the execution belonged to Arjuna Ranatunga and his team. But the foundation for that victory was laid long before.

✔ The experience of playing Test cricket for 15 years before 1996 gave us the mental toughness to win.

✔ The confidence to take on the world’s best was born from the fight for Test recognition.

✔ The belief that Sri Lanka could win on the global stage was a lesson my father instilled in everyone who worked with him.

Without that long-term vision, Sri Lanka may have still been waiting for its moment of cricketing glory.

That is what great leadership does—it creates opportunities that allow future generations to succeed.

My Role in Continuing His Legacy Through the Sri Lanka Cricket Foundation

Today, Sri Lankan cricket stands at another crossroads.

We are a country that has lifted the World Cup, produced some of the greatest cricketers in the world, and built a reputation for playing brave, fearless cricket.

But we are also a cricketing nation struggling with inconsistency, administrative challenges, and lost opportunities.

That is why, as Chairperson of the Sri Lanka Cricket Foundation, I feel an immense responsibility—not just to honour my father’s work, but to continue it in ways that will shape the next era of Sri Lankan cricket.

Here’s what we are focusing on at the Sri Lanka Cricket Foundation:

✔ Developing Young Talent Nationwide – My father believed that talent is everywhere, but opportunity is not. Through the Cricket Foundation, we are working to strengthen school cricket programmes, identify hidden talent across rural areas, and support the next generation of Sri Lankan cricketers.

✔ Improving Cricketing Infrastructure – While our international stadiums are recognised worldwide, our grassroots cricket facilities need urgent investment. We are working to equip schools and clubs with better training facilities so that young players can develop under proper conditions.

✔ Restoring Professionalism & Transparency in Administration – Cricket should always be led by those who genuinely care for the game, not by those looking for personal gain. Through the Cricket Foundation, we are promoting stronger governance, better planning, and a long-term approach to cricket development.

✔ Bringing Back the Sri Lankan Cricket Identity – We were once known as the most unpredictable, fearless, and entertaining cricket team in the world. That identity must be rebuilt from the grassroots up.

The game gave us our proudest moments as a nation—it must never be allowed to decline.

Looking Ahead: A Legacy That Still Guides Us

Thirty years after his passing, my father’s vision still lives on in Sri Lanka’s cricketing institutions, in our stadiums, in our players, and in our history.

But his work is not finished.

As we honour him on his birth anniversary, my hope is not just to celebrate his achievements, but to continue his mission.

He fought to put Sri Lanka on the map of world cricket.

Now, it is our turn to fight to keep it there.

Because Sri Lanka’s place in world cricket was never handed to us on a platter—it was earned. And we must always be ready to earn it again.

Research: Understanding basics and getting started – Part II

Published

on

(Part I of this article appeared yesterday)

Identification of a Research Problem

A well-defined research problem is the foundation of any meaningful research. It serves as the driving force that shapes the research process, distinguishing it from a general essay, where a research problem is not necessarily required. In an essay, one may present an argument or analysis without systematically addressing an unresolved question. However, in research, identifying a research problem is essential because it establishes the purpose and direction of the study.

A research problem arises in situations where a) The answer is entirely unknown, b) There are multiple, often conflicting answers.) Existing answers are inadequate or unsatisfactory.

A strong research problem should ideally be theoretical and analytical rather than merely descriptive. This means that the issue under investigation should contribute to a broader body of knowledge and be applicable beyond a single case. A well-formulated research problem allows for systematic inquiry, critical engagement with existing literature, and the development of new insights that can be tested, debated, and applied in different contexts.

Effective research problems often emerge from gaps in existing knowledge, inconsistencies in theoretical perspectives, or unresolved debates within a particular field. Researchers must critically assess prior studies, identify limitations, and frame their research problem in a way that advances scholarly understanding.

How to begin a research?

Research begins with the identification of a problem. A well-defined problem is the foundation upon which the entire study is built. Without a clear and focused problem, the research lacks direction. Once the problem is identified, the next step is to define it in specific terms, ensuring that the scope is manageable and relevant.

The process of research starts with recognising a gap in existing knowledge or a real-world issue that requires exploration. This problem could arise from theoretical questions, societal needs, or unresolved practical challenges. Once identified, the problem must be clearly defined to guide the research process and ensure that the results are meaningful and applicable.

Once the research problem is clearly defined, the next step is to form hypotheses. Hypotheses are educated guesses or assumptions based on initial observations of the problem. They provide a tentative explanation or prediction that can be tested through research. Hypotheses guide the direction of the study, suggesting what the researcher expects to find or how the problem might be addressed.

Hypotheses are used to gather data. Researchers design methods, such as experiments, surveys, interviews, or observations, to collect information that either supports or challenges the hypotheses. The type of data collected will depend on the nature of the problem and the hypotheses being tested.

The validity of hypotheses is tested through experimentation, further observations, and surveys. Researchers analyze the data to determine whether the hypotheses are supported or refuted. If the data aligns with the hypothesis, it can be considered as supporting evidence. Conversely, if the data contradicts the hypothesis, it must be refuted, prompting a reevaluation of the research approach or the formulation of new hypotheses.

Observations and Surveys: Two Key Components of the Research Process

Observation is a systematic and focused approach to perceiving and understanding something. It is the initial step in the research process that involves actively perceiving a phenomenon, recording what is seen, and seeking to derive meaning from the observed data.Observation often serves as the foundation for testing a theory or hypothesis. By observing the world, researchers gather real-world data that either supports or challenges established theories or hypotheses.The insights derived from observation provide the initial data necessary for deeper analysis. They allow researchers to identify variables and relationships that will be examined in subsequent steps of the research.While observation is critical, it is not sufficient on its own for acquiring deeper knowledge. It offers descriptive data but requires further investigation and interpretation to draw conclusions about underlying causes or implications.

A survey is a methodical process for collecting and analysing data through direct examination of facts, measurements, and other variables. Surveys are typically structured to gather quantitative data, offering a broad understanding of the subject under study.Surveys often involve the measurement of specific variables, whether through numerical data or other measurable factors, to understand their magnitude or distribution.Surveys involve systematically recording factors and variables that could influence or explain the research phenomenon. These records often serve as a comprehensive database for analysis.The data collected through surveys is often categorized into relevant groups, which helps in identifying trends, correlations, and potential insights that can further inform the research process.In sum, both observation and survey are integral to the research process.

Collection and Examination of Data

The collection of data is a fundamental and initial step in any research. Data is raw, unprocessed information—experience without interpretation. It is akin to a signal that provides useful information but without context or meaning.

One of the fundamental principles of data collection is the distinction between objectivity and subjectivity. Objectivity ensures that data is gathered free from personal bias or interpretation, maintaining neutrality and factual accuracyIncontrast, subjectivity, personal perspectives, prejudices and experiences, can distort data and lead to inaccurate conclusions. This distinction underscores the principle that facts are sacred; opinions are free—facts should remain unaltered by personal bias, while opinions are inherently subjective and open to interpretation.

Once collected, data must be systematically categorised to facilitate analysis and interpretation. Traditionally, it has been classified as primary or secondary, but this distinction is increasingly seen as outdated, as the boundaries between these categories have blurred. Contemporary research prioritises a more nuanced approach that considers data sources, context, and potential biases.

There is no one-size-fits-all approach to data collection in research. The choice of methods depends on the field of study and the specific research questions. Broadly speaking, research methods are categorized into qualitative and quantitative approaches. Qualitative methods, such as interviews, focus groups, and ethnography, aim to explore underlying themes, perceptions, and experiences. The data collected is often non-numerical and lends itself to in-depth analysis within natural contexts. In contrast, quantitative methods involve the collection of numerical data through surveys, experiments, or statistical analysis. These methods are typically used to test hypotheses, identify patterns, and generate statistical insights.

Beyond these methods, advancements in data science and emerging technologies have revolutionised data collection and analysis. From big data analytics to AI-driven tools, modern research methods are expanding how data is gathered, categorized, and interpreted.

Critical examination of data is an essential element in research, as it ensures the validity and reliability of findings. A commonly used method for examining data is through analysis and synthesis. Analysis involves a detailed and systematic examination of data by breaking it down into parts, features, and qualitieswhile synthesis allows them to integrate and combine information from different sources to form a comprehensive understanding. This requires thoughtful consideration and reasoning to uncover patterns, relationships, and underlying structures.

Main steps in the research process

Identification of Research Problem: The first step in any research process is to clearly define the problem you want to explore. This involves understanding the issue at hand, reviewing existing literature to see what has been researched before, and pinpointing gaps in knowledge. A well-defined research problem sets the stage for the entire project and guides the subsequent steps.

Hypothesis Formation: Once the problem is identified, the next step is to form a hypothesis or a tentative statement that predicts the outcome of the research. A hypothesis should be based on existing theory or observations. It acts as the foundation for guiding the research design.

Making Observations: This step involves gathering preliminary information through direct observation, literature review, or secondary data collection. Observations help refine the research questions further and build an understanding of the context. It’s essential to document the information you observe systematically to identify patterns or insights.

Conducting Surveys: Surveys, interviews, or experiments are commonly used tools to gather primary data. Depending on the nature of the research, surveys help collect data from participants to support or challenge the hypothesis. It’s crucial to design surveys carefully, ensuring they are valid, reliable, and ethical, while aligning with the research objectives.

Building Concepts: After gathering data, the next step is to analyze and organise the information. This may involve creating new concepts or refining existing ones, categorising the data, and identifying relationships between variables. Building concepts helps transform raw data into meaningful insights that are necessary for drawing conclusions.

Arriving at Judgments: At this stage, researchers evaluate the data and test the hypothesis. They assess whether the findings align with the initial hypothesis or if new interpretations are needed. This is the point where critical thinking and analysis come into play to determine the significance and implications of the findings.

Making Conclusions: The final step in the research process is drawing conclusions based on the evidence gathered throughout the study. This includes interpreting the results, explaining how they address the research problem, and offering recommendations for future research or practical applications. It’s also important to acknowledge limitations and suggest ways in which the research can be expanded.

Unpacking Scientific
Research Method

Since the 1970s, the Linguistic Turn in Western philosophy has critically re-examined the assumptions underlying the traditional scientific research approach. This intellectual shift, influenced by thinkers such as Friedrich Nietzsche, Wilhelm Dilthey, and Martin Heidegger, challenged the idea that knowledge could be purely objective and independent of language. Their work laid the groundwork for later scholars who argued that language, interpretation, and human experience fundamentally shape our understanding of truth and reality.

The Linguistic Turn prompted a reconsideration of several foundational premises of the scientific method, particularly its claims to neutrality and universality. Below are key aspects of this intellectual movement and its impact on the philosophy of knowledge and science:

The Truth or Truths:

Traditional scientific thought holds a singular, objective truth that is discoverable through empirical research. However, philosophers of the Linguistic Turn, influenced by Nietzsche’s critique of objective truth, argued that truth is not absolute but is contingent on language, culture, and perspective. Truths, therefore, are plural and are shaped by the subjective frameworks we use to understand the world.

Knowledge – Truth Nexus:

In Modern Science, knowledge is seen as a pathway to uncovering truths about the world, grounded in objective observation. The Linguistic Turn, however, proposed that knowledge itself is not neutral or purely empirical, but deeply intertwined with the language we use to interpret our

experiences. It suggests that knowledge is always mediated by linguistic and cultural structures, making it subject to interpretation rather than a direct reflection of objective reality.

Objectivity of Data:

The scientific method relies on the assumption that data can be collected and interpreted in an objective, unbiased manner. Yet, thinkers like Heidegger and Dilthey contended that all human understanding, including the analysis of data, is inherently influenced by subjective preconceptions and historical contexts.

Subjectivity – Objectivity Dichotomy:

The traditional Scientific Approach draws a sharp line between subjectivity (personal bias, emotions, etc.) and objectivity (rational, detached analysis). The Linguistic Turn critiques this dichotomy; subjectivity cannot be entirely separated from objectivity. Knowledge and truth are seen as always influenced by the individual’s perspective, background, and language, making the separation of the two a false ideal.

Uni-lineal Progress:

The Scientific Approach is often grounded in the assumption of linear progress, where each discovery necessarily leads to a subsequent advancement in understanding. However, drawing on the ideas of Nietzsche and Heidegger, Jean-François Lyotard challenged this assumption, arguing that progress is not always linear. He contended that historical and cultural contingencies significantly influence the trajectory of intellectual and scientific development. Thus, the concept of linear progress is an oversimplification of a far more complex and multifaceted reality.

Grand (Meta) Narration: The Scientific Research Approach often embraces grand narratives—overarching theories or models that aim to explain all phenomena in a single, unified framework (e.g., theories of evolution, theories of relativity). The Linguistic Turn, however, challenges the validity of such grand narratives, arguing that they tend to exclude alternative perspectives and experiences. The focus, instead, shifts toward smaller, local narratives that acknowledge complexity and difference, emphasizing the plurality of viewpoints rather than one dominant, overarching explanation.

The intellectual revolution sparked by the Linguistic Turn has significantly reshaped how we approach knowledge, truth, and research, urging a more nuanced and critical engagement with the scientific paradigm. By emphasizing the role of language, interpretation, and historical context, it calls into question the objectivity and universality that were once the cornerstones of scientific inquiry.
