Poverty is a persistent global issue that affects millions of people worldwide. Despite progress made in reducing poverty rates, in 2020 an estimated 711 million people still lived in extreme poverty on less than $1.90 a day (World Bank, 2020). Poverty is complex and multidimensional, encompassing lack of income and deprivation of basic human needs including food, clean water, sanitation, healthcare, shelter, education, and information. Poverty has severe impacts on quality of life, health, and limits opportunities to achieve full potential. There are various challenges and debates regarding how to most effectively reduce poverty globally, regionally and nationally. Comprehensive strategies that address systematic and structural causes are required. This paper will provide an overview of: the scope, impacts and measurement of global poverty; key challenges; debates regarding economic growth versus distributional policies; and strategies for fighting poverty through economic growth, social policies, development aid, and addressing environmental sustainability.
Scope and Measurement of Global Poverty
The number of people living in extreme poverty as defined by the international poverty line has declined substantially over recent decades, despite continued population growth. In 1990 nearly 2 billion people lived on less than $1.90 a day, compared with 711 million in 2020 (World Bank, 2020). The global extreme poverty rate decreased from 36 percent to 9 percent over this period. The most rapid declines occurred in East Asia and the Pacific, however Sub-Saharan Africa still has the highest rates of extreme poverty. Projections indicate that approximately 7 percent of the world will still live in extreme poverty by 2030 if current trends continue (World Bank, 2020).
However, measuring poverty involves complex methodological challenges. The most common approach is to establish an international poverty line (IPL) based on minimal income required to meet basic needs. The World Bank determined $1.90 per day was the average of national poverty lines among the world’s poorest countries. But the IPL has limitations, as purchasing power, access to basic services, nutrition and living standards vary considerably across countries at the same income level. Multidimensional measures of poverty have been developed to capture overlapping deprivations including the UNDP’s Multidimensional Poverty Index and the Oxford Multidimensional Poverty Index. These incorporate health, education, living standards and assets indicators. The IPL also does not account for vulnerability, inequality of opportunity, social exclusion and other qualitative dimensions of poverty. Relative poverty compares low income to the standards of the society in which a person lives, reflecting inequality. These more nuanced measures reveal higher poverty rates than IPL estimates (UNDP, 2021).
Impacts of Poverty
Poverty has severe, intersectional and cyclical impacts on individuals, communities and nations. It is associated with material deprivation – lack of basic resources, goods and services – and undermines human dignity and rights. The poor face precarious livelihoods, malnutrition, hunger, poor health, high mortality rates, homelessness, unsafe environments, social marginalization, lack of political power and limited opportunities for socioeconomic mobility (UN, 2021).
Poverty disproportionately affects women, children, disabled, elderly and minorities. Women represent 70 percent of the world’s poor due to lower wages, fewer assets, and less access to education, finance and justice compared to men (UN Women, 2018). Children growing up in poverty often maintain impoverishment into adulthood through diminished education, health and earning potential. This can perpetuate intergenerational poverty cycles.
On a national level, high poverty rates inhibit economic development and prosperity. Poverty limits productive capacity and consumer demand. Hardship can trigger social unrest and political instability. Poverty reduction is therefore imperative for economic growth, demographic transition, national security and global stability (Sachs, 2005). Sustainable Development Goal 1 aims to end poverty in all its forms everywhere by 2030. This requires tackling both income and non-income aspects of poverty.
Challenges in Fighting Poverty
Despite the ethical imperative and known impacts of poverty, effectively reducing it globally remains complex and challenging. Key debates relate to the primacy of distributional policies versus economic growth strategies. There are also considerable challenges in implementation of anti-poverty programs and targeting those most in need.
- Systemic and Structural Causes
A fundamental challenge is that poverty has systemic and structural origins so cannot be solved by short-term or limited interventions alone. Poverty is intrinsically linked to lack of income and assets, so generating equitable economic growth and employment are critical. However, broader factors that entrench poverty also need addressing including lack of social protection, disadvantages based on gender, ethnicity, geography, governance failures and social exclusion (Shepherd et al., 2014). Those in poverty often lack political power to catalyze reform. Transformational change tackling these structural inhibitors is essential for sustainable poverty alleviation.
- Inequality
Poverty is strongly associated with inequality in access to income, resources and opportunities. Global income inequality has declined between nations over recent decades as populous countries like China and India have experienced rapid economic growth. But inequality within many countries has concurrently risen (UNDP, 2019). The poorest segments often lack means for socioeconomic mobility. Even with overall growth, poverty persists when gains disproportionately benefit the rich. Tackling inequality is therefore integral to poverty strategies, using redistributive policies, progressive taxation, social protection schemes, increased minimum wages andGender inequality specifically undermines poverty reduction so must be addressed. Rural-urban disparities also remain pronounced (UN, 2021).
- Conflict and Fragility
Conflict, violence and climate disasters can devastate development and dramatically escalate poverty. Fragile and conflict states are home to just 10% of the world’s population but two thirds of those living in extreme poverty (World Bank, 2020). People fleeing conflict often lose assets and livelihoods. Reconstruction of institutions, infrastructure and economies in these nations is vital but challenging. External assistance and humanitarian aid provide crucial temporary relief. But long-term strategies promoting stability and resilience are imperative.
- Health, Nutrition and Population Growth
Poor health and malnutrition are both key dimensions and consequences of poverty. Nutrition in mothers and infants, sanitation, healthcare access and education are all linked to poverty status. Resulting hunger and disease create immense human suffering and inhibit productivity. High birth rates and large families are also associated with poverty, creating demographic challenges particularly in sub-Saharan Africa. Providing healthcare, nutrition, family planning assistance, education and clean water are essential but require substantial, sustained investment and political will.
- Climate Change
Climate change is a central challenge, as those in poverty typically rely on climate sensitive sectors like agriculture. Impacts such as droughts, floods and changing seasons can devastate livelihoods, food security and drive migration. Environmental degradation also disproportionately affects poor communities. Climate change exacerbates poverty, yet poverty leaves people least equipped to adapt (UN, 2021). Low-carbon, climate resilient development is required, along with assistance to those impacted. But policies risk placing unjust burdens on those with minimal historic emissions.
- Limitations of Past Strategies and Aid
While poverty has declined, past efforts have had shortcomings. Top-down policies often failed to sufficiently include or empower the poor. Corruption undermined aid effectiveness. Neoliberal capitalist ideologies driving deregulation and privatization exacerbated inequality in many instances. Rapid industrialization had environmental costs and primarily benefited elites. Strategies narrowly targeting income were inadequate for multidimensional poverty. Development assistance totaling trillions of dollars yielded mixed results. There remains debate around improving aid quality and recipients’ ownership, along with balancing human rights and effectiveness (Gore, 2000). Poverty alleviation requires policy evolution and new approaches.
Economic Growth Strategies
Generating broad-based economic growth and decent employment are foundational and frequently cited strategies for reducing absolute poverty. With growth, resources available for redistribution expand and additional households can attain sufficient income. But the quality and inclusivity of growth processes, along with complementary policies, significantly determine impacts on poverty.
Export Oriented Industrialization:
Historically, manufacturing industry development succeeded in lifting many East Asian countries out of poverty. This involved export orientation using low-cost labor without strong welfare policies. Critics argue it exploited workers and primarily benefited elites (Shepherd et al., 2014). But it remains a common growth model, with caveats.
Job Creation:
Unemployment and informal, vulnerable employment are key drivers of poverty. Policies fostering private sector growth and decent job creation are vital, but must also address barriers to work including skills gaps, discrimination and lack of childcare (UN,2021). Governments play a role in ensuring acceptable working conditions and ‘bottom-up’ input in employment policies by the poor.
Infrastructure Investment:
Infrastructure like electrification, sanitation systems, roads and internet access can catalyze development and improve healthcare, education, productivity and connectivity for impoverished communities. This raises incomes and living standards. But projects should build local skills and procurement.
Financial Inclusion:
Access to savings, credit, payments and insurance can help the poor increase incomes, accumulate assets and better cope with financial shocks. However, efforts to increase responsible financial inclusion must ensure consumer protection and affordability (World Bank, 2018).
Agriculture Productivity:
In many developing countries, improving yields, efficiency and market access for smallholder farmers is integral. This can raise incomes and reduce malnutrition. But environmentally sustainable practices are essential, along with strengthened land rights and inclusion of women farmers (UN, 2021).
Social Entrepreneurship:
Enterprises aiming for social as well as financial returns can assist impoverished communities while operating sustainably without ongoing external support. Benefits include adapted goods and services, employment and local engagement. Governments and impact investors can encourage social entrepreneurship (Abu-Saifan, 2012).
Education and Skills Training:
Education strongly correlates with higher earnings potential. Equitable access to quality education, including secondary and vocational, plus skills training specific to market needs enable socioeconomic mobility. But costs can impede participation by the poor unless addressed.
Targeted efforts in these areas allow the poor to contribute to and benefit from economic growth. But growth alone is insufficient without redistribution. Inclusive growth requires policies that expand opportunities and assets for the poor, while curbing potential marginalization and environmental damage.
Social and Redistributional Policies
Due to the inherent limits of relying solely on growth, direct policy interventions aimed at redistribution and poverty alleviation are also vital. These counteract excessive inequality generated through unfettered markets, mitigate vulnerabilities associated with poverty and expand access to services that improve welfare. Social transfers, progressive taxation, labor regulation and public service provision are key mechanisms, but require effective institutions and funding mechanisms.
Social Assistance and Insurance:
Cash transfers, food aid, subsidies, pensions and employment guarantee schemes directly increase income and consumption. Transfers targeted based on poverty status avoid leakage to the non-poor. Insurance prevents descent into poverty after crises. But programs must have adequate coverage, size, delivery and continuity to meaningfully reduce poverty. Funding constraints can limit scale.
Progressive Taxation and Regulation:
Tax policies that draw more revenues from the wealthy help redistribute and fund social programs through principles of universality and contribution based on ability to pay. Enforced minimum wages, worker protections and anti-discrimination laws also counter market-driven inequality. But expanding formal employment and effective institutions are preconditions.
Public Services and Infrastructure:
Government funded healthcare, education, water, sanitation, electricity and transportation infrastructure improve welfare and earnings potential. But quality implementation is essential. User fees can exclude the poorest unless subsidized or waived.
Empowerment and Governance:
Legal protections for women and minorities, along with political representation for the poor, are necessary to transform inequitable structures. Participatory policymaking and decentralization can enhance responsiveness and accountability to the disadvantaged. But institutionalizing participation is challenging.
Overall, redistributive mechanisms reduce inequality and the impacts of poverty, but can have high budgetary costs. Funding sources like progressive taxation and curbing corruption are therefore crucial. The optimal policy mix considers affordability, capabilities, and incentives balancing equity and growth. But commitment is essential. Social protection floors providing basic income security and access to services are increasingly recognized as a universal right and sustainable means for poverty alleviation (ILO, 2019).
International Development Aid
While domestic policies are central, for the poorest countries international development aid and philanthropy remain vital temporary measures. Critiques question past efficacy and whether assistance perpetuates dependence, but empirical evidence finds it supports growth and poverty reduction when appropriately targeted (Arndt et al., 2015). Total official development assistance reached $161 billion in 2020, reflecting 0.32% of donor country income, but remains below the 0.7% UN target (OECD, 2021). Expanding aid requires increased commitments among wealthy nations along with reforms to enhance impact. Channeling assistance directly to needy recipients through new technologies like mobile transfers and innovative financing tools can also improve effectiveness.
Aid should fund developing country priorities like health, agriculture, infrastructure, environmental sustainability and strengthening institutions – areas catalytic for poverty alleviation but underfunded by markets. Good governance, women’s empowerment, and trade capacity building further enable poverty reduction while preventing reliance on aid. Long-term recipient engagement and aligned incentives improve project outcomes. Reducing debt burdens and improving access to affluable finance, medicines and technologies promotes growth. While aid alone is insufficient without national public sector and policy efforts, targeted aid remains a moral imperative and valuable supplement to domestic initiatives. More equitable trade and tax regimes reducing illicit financial flows would also enable greater self-reliant and sustainable development.
Environmental Sustainability
Environmental degradation disproportionately harms the poor and threatens to exacerbate poverty, while sustainable approaches can provide direct benefits through conservation, ecotourism income and smallholder agriculture (UNDP, 2011). All poverty reduction strategies must therefore account for climate change mitigation and adaptation needs, especially regarding clean energy access which both spurs growth and reduces pollution’s health impacts. Ecosystem based approaches are also essential for sustaining livelihoods. But balancing environmental protection with poverty alleviation requires careful policy design to avoid overburdening disadvantaged groups. Means tested subsidies can encourage sustainable behaviors while minimizing costs to the poor, who contribute least to climate change historically. With sustainable development principles, environmental policies present opportunities rather than just costs.
Key Takeaways and Conclusions
- Poverty is multifaceted, has severe impacts and stems from systemic disadvantages that require comprehensive solutions. Sustained, inclusive growth coupled with well-designed redistributive policies and social protection are proven, effective strategies.
- But inequality, fragility, poor governance, demographics, climate change and past failings pose challenges requiring adapted approaches. No simple policy blueprint exists. Context-specific solutions with country ownership are imperative.
- Sustainable Development Goal 1 provides an important roadmap, recognizing both income and social dimensions. Progress requires long-term commitment, resources and accountability from national governments along with development partners.
- Participation, empowerment and new insights must inform solutions. While past top-down policies failed, so did pure market-driven neoliberalism. Redistribution and growth should complement one another. Policy discussions must shift from whether governments intervene to how they can do so most effectively.
- Eliminating poverty in our increasingly globalized world is complex but necessary and achievable. It requires sustained collaboration, funding, political will, compassion and dedication to evidence-based policies focused on the poorest. With comprehensive, thoughtful efforts we can consign extreme poverty to history.
