From Economic Growth to Sustainable Development: A Comparative Study
The concepts of growth and development, in addition to sustainable development, occupy a prominent place in economic and social literature, given their importance in the trajectories of nations' progress and the well-being of their peoples, particularly in developing countries where broad segments of society suffer from poverty and economic vulnerability (Todaro & Smith, 2015). For a long time, the concept of economic growth, with its quantitative dimension, dominated this literature as the primary indicator of progress and economic development (Solow, 1956).
However, rapid economic and social transformations, along with the repercussions of growth and development on the environment, led to the emergence of sustainable development as the most comprehensive framework (WCED, 1987), encompassing integrated dimensions that include the environmental dimension alongside economic, social, technical and cultural aspects. Consequently, economic growth, measured by its quantitative metrics alone, is no longer an end in itself, but has become a means within a broader developmental path (Daly, 1996), in which sustainable development represents a modern and more comprehensive concept than traditional notions of growth and development.
Economic growth is defined as the cumulative increase in the volume of net investment, coupled with technical progress resulting from the adoption of modern machinery and technologies, alongside the development of labour force qualifications and the enhancement of its efficiency. It aims to raise productivity, expand productive capacities and increase the output of goods and services over a given period of time to meet the needs of individuals in society (Romer, 1990).
Economic growth often requires the use of natural resources that are mostly non-renewable, entails environmentally unfriendly productive and service activities, and generates outputs that may have negative environmental effects, thereby raising the cost of growth in the short term and threatening, in the long term, the sustainability of natural resources for future generations (Daly, 1996).
The achievement of economic growth in a given country is evidenced by increases across a set of quantitative economic indicators, foremost among them gross national income (GNI) and gross domestic product (GDP), provided that their growth rate exceeds both population growth on the one hand and inflation on the other, so as to translate into a real improvement in average per capita income and living standards, as well as a reduction in unemployment rates (Kuznets, 1973).
Historically, Ibn Khaldun is considered one of the earliest thinkers to examine the question of growth within an analytical framework. In his view, growth is measured by the degree of civilisation, which he regards as a complex, cumulative process in which diverse economic, social, geographical, political and ideological factors interact. The role and effectiveness of these factors change from one period to another, causing the growth process to accelerate or slow down, then come to a halt, and subsequently decline, before returning once again to generate renewed development, and so on (Ibn Khaldun, 2004).
Economic development is a process aimed at converting increased economic growth into tangible progress at both the social and technical levels. Conversely, once achieved, development plays a pivotal role in bolstering economic growth, which in turn translates into advances in the technical and social spheres (Seers, 1969; UNDP, 1990).
The concepts of growth and development are linked by an interactive, complementary relationship, as both focus primarily on the economic dimension; however, the concept of economic development is broader because it encompasses qualitative changes in addition to quantitative and structural ones.
Economic development contributes to the redistribution of wealth, bringing about tangible shifts in consumption patterns and habits. It also generates job opportunities, enabling a wider segment of the labour force to participate in the productive process, while helping to reduce poverty rates and improve social and economic conditions.
The goals of development have evolved and its scope has expanded from creating material wealth and producing goods to meet basic human needs, to encompassing social and human factors, and ultimately to achieving economic growth and prosperity with an emphasis on redistributing income in favour of the poor and marginalised groups.
Development is not confined to boosting consumption and increasing purchasing power alone, but encompasses all social aspects that contribute to improving living standards and raising individual well-being. It reflects the state's capacity to keep pace with the demands of expanding productive sectors and to provide infrastructure and basic services, serving as a general indicator of achieved development and improved macroeconomic performance (Seers, 1969; UNDP, 1990).
Economic development expresses the capacity of the national economy to achieve cumulative increases in macroeconomic indicators at rates exceeding the minimum required to ensure the continuity of economic activities and the renewal of productive tools, with such increases typically estimated at rates ranging from 2 to 5 per cent and above.
While growth theories reflect the concerns of advanced countries, development theories address the economic problems of developing nations (Al-Eisawi, 2000).
The United Nations conference in 2000, known as the "Millennium Summit", defined the purpose of development in a document titled "The Millennium Development Goals" (MDGs), which set out eight specific and measurable goals. These include eradicating extreme poverty and hunger, achieving universal primary education, reducing child mortality rates, promoting gender equality and empowering women, improving maternal health, combating diseases, ensuring environmental sustainability, and developing a global partnership for development (United Nations, 2000).
Sustainable development is a relatively recent concept in contemporary development thought, representing a multidimensional process based on achieving development that meets the needs of present generations while safeguarding the ability of future generations to meet their own needs by respecting their rights to natural resources and wealth. This principle forms the core ethical and philosophical dimension of the concept of sustainable development (WCED, 1987).
Sustainable development aims to establish balanced economic, social and environmental development (Sachs, 2015), focused on improving the quality of human life in parallel with protecting ecosystems and rationalising the use of natural resources, thereby ensuring their continuity and availability for future generations. Accordingly, measuring sustainable development is not limited to economic indicators alone, but includes social, cultural and environmental indicators, making it more comprehensive and suitable than the traditional models of development and growth that preceded it.
Sustainable development serves as a guiding framework for economic and social policies, seeking to reconcile the requirements of economic growth with the mitigation of its negative environmental effects, in order to protect human beings from risks, safeguard their stability and secure their well-being, while improving their material and social quality of life over the long term (OECD, 2001).
Sustainable development also aims to help build societies in which manifestations of poverty and inequality recede, the irrational exploitation of natural resources is curbed, and the adverse effects of distortions in scientific and technical progress are mitigated. Achieving these goals requires interaction and integration among various stakeholders, including governments, official institutions and civil society organisations, thereby enhancing the prospects for effective and sustainable development (Sen, 1999).
Indicators of sustainable development encompass four main pillars reflecting its comprehensive developmental dimensions: economic indicators, social indicators and environmental indicators, as well as institutional indicators, which together constitute essential analytical tools for assessing progress towards sustainable development (United Nations, 2007).
On the economic front, sustainability is measured through a set of indicators reflecting the economy's capacity to achieve continuous and balanced growth without undermining resources or financial and social stability. Prominent among these indicators are the real economic growth rate, the level of productive investment, resource-use efficiency, public finance stability and income distribution, in addition to employment and productivity rates. These indicators are used to assess the economy's ability to generate wealth sustainably and equitably.
On the social front, social sustainability is measured through indicators concerned with improving quality of life and promoting social justice, including poverty and unemployment rates, education levels and enrolment ratios, public health indicators, population growth, and equal opportunity across different social groups. The "Social Development Index" is one of the primary tools in this domain, providing a quantitative framework for measuring social progress and the inclusiveness of the fruits of development.
With regard to the environmental dimension, environmental sustainability is measured through indicators designed to assess the environmental impact of economic and developmental activities, and the extent to which ecosystems and natural resources are preserved. The "Ecological Footprint Index" is among the most prominent of these tools, making it possible to determine how compatible production and consumption patterns are with the carrying capacity of the environment (Wackernagel & Rees, 1996).
Institutional indicators, meanwhile, measure the efficiency of institutional frameworks and good governance, as well as the capacity of institutions to support sustainable development pathways. These indicators include the quality of legislation and public policies, levels of transparency and accountability, the effectiveness of public administration, the rule of law, and civil society participation in decision-making. Such indicators are a decisive factor in ensuring the sustainability of developmental outcomes over the long term (World Bank, 1992).
Consequently, sustainable development constitutes a more comprehensive and integrated model, predicated on achieving economic progress alongside social justice and environmental protection, while respecting the rights of future generations. Rather than measuring success solely by growth or income rates, it focuses on quality of life, resource sustainability, social cohesion and good governance.
Based on the foregoing, sustainable development acquires exceptional importance for Lebanon amid the compounded economic, financial, social and environmental crises afflicting the country. Economic growth in its traditional sense is no longer sufficient to address structural imbalances, secure social justice or protect limited natural resources (ESCWA, 2020).
In particular, sustainable development allows economic policies to be redirected towards sustainable productivity rather than rentierism and waste, while strengthening institutional frameworks and good governance so as to rebuild trust between the state and society. Sustainable development also promotes social justice and curbs poverty, unemployment and emigration on the one hand, while protecting natural resources, especially water, energy and land, from depletion and degradation on the other.
Accordingly, sustainable development offers the most appropriate framework for leading Lebanon out of its multiple crises, building a balanced developmental path that ensures economic and social stability, preserves the rights of present and future generations, and reconnects economic growth with comprehensive human development.
