Human security is a paradigm for understanding global vulnerabilities whose proponents challenge the traditional notion of national security through military security by arguing that the proper referent for security should be at the human rather than the national level, and that a people- centered view of security is necessary for national, regional and global stability. The concept emerged from a multi-disciplinary understanding of security which involves a number of research fields, including development studies, international relations, strategic studies, and human rights. The United Nations Development Programme's 1994 Human Development Report is considered a milestone publication in the field of human security, with its argument that ensuring "freedom from want" and "freedom from fear" for all persons is the best path to tackle the problem of global insecurity.United Nations Development Programme (1994): Human Development Report

Critics of the concept argue that its vagueness undermines its effectiveness, that it has become little more than a vehicle for activists wishing to promote certain causes, and that it does not help the research community understand what security means or help decision-makers to formulate good policies.For a comprehensive analysis of all definitions, critiques and counter-critiques, see Tadjbakhsh, Shahrbanou & Chenoy, Anuradha M. Human Security: Concepts and Implications, London: Routledge, 2006Paris, Roland (2001): Human Security - Paradigm Shift or Hot Air? In: International Security, Vol. 26, No. 2. 87–102.online Alternatively, other scholars have argued that the concept of human security should be broadened to encompass military security: 'In other words, if this thing called 'human security' has the concept of 'the human' embedded at the heart of it, then let us address the question of the human condition directly. Thus understood, human security would no longer be the vague amorphous add-on to harder-edged areas of security such as military security or state security.'

In order for human security to challenge global inequalities, there has to be cooperation between a country's foreign policy and its approach to global health. However, the interest of the state has continued to overshadow the interest of the people. For instance, Canada's foreign policy, "three Ds", has been criticized for emphasizing defense more than development.

Origins The emergence of the human security discourse was the product of a convergence of factors at the end of the Cold War. These challenged the dominance of the neorealist paradigm's focus on states, "mutually assured destruction" and military security and briefly enabled a broader concept of security to emerge. The increasingly rapid pace of globalization; the failure of liberal state-building through the instruments of the Washington Consensus; the reduced threat of nuclear war between the superpowers, and the exponential rise in the spread and consolidation of democratization and international human rights norms opened a space in which both 'development' and concepts of 'security' could be reconsidered.

At the same time, the increasing number of internal violent conflicts in Africa, Asia and Europe (Balkans) resulted in concepts of national and international security failing to reflect the challenges of the post Cold War security environment whilst the failure of neoliberal development models to generate growth, particularly in Africa, or to deal with the consequences of complex new threats (such as HIV and climate change) reinforced the sense that international institutions and states were not organized to address such problems in an integrated way.

The principal possible indicators of movement toward an individualized conception of security lie in the first place in the evolution of international society's consideration of rights of individuals in the face of potential threats from states. The most obvious foci of analysis here are the UN Charter, the UN Declaration of Human Rights (1948) and its associated covenants (1966), and conventions related to particular crimes (e.g., genocide) and the rights of particular groups (e.g., women, racial groups, and refugees).

Concept

UNDP's 1994 definition Mahbub ul Haq first drew global attention to the concept of human security in the United Nations Development Programme's 1994 Human Development Report and sought to influence the UN's 1995 World Summit on Social Development in Copenhagen. The UNDP's 1994 Human Development Report's definition of human security argues that the scope of global security should be expanded to include threats in seven areas:

Economic security – Economic security requires an assured basic income for individuals, usually from productive and remunerative work or, as a last resort, from a publicly financed safety net. In this sense, only about a quarter of the world's people are presently economically secure. While the economic security problem may be more serious in developing countries, concern also arises in developed countries as well. Unemployment problems constitute an important factor underlying political tensions and ethnic violence. Food security – Food security requires that all people at all times have both physical and economic access to basic food. According to the United Nations, the overall availability of food is not a problem, rather the problem often is the poor distribution of food and a lack of purchasing power. In the past, food security problems have been dealt with at both national and global levels. However, their impacts are limited. According to the UN, the key is to tackle the problems relating to access to assets, work and assured income (related to economic security). Health security – Health security aims to guarantee a minimum protection from diseases and unhealthy lifestyles. In developing countries, the major causes of death traditionally were infectious and parasitic diseases, whereas in industrialized countries, the major killers were diseases of the circulatory system. Today, lifestyle-related chronic diseases are leading killers worldwide, with 80 percent of deaths from chronic diseases occurring in low- and middle-income countries.World Health Organization, "Chronic Diseases" http://www.who.int/topics/chronic_diseases/en/ According to the United Nations, in both developing and industrial countries, threats to health security are usually greater for poor people in rural areas, particularly children. This is due to malnutrition and insufficient access to health services, clean water and other basic necessities. Environmental security – Environmental security aims to protect people from the short- and long-term ravages of nature, man-made threats in nature, and deterioration of the natural environment. In developing countries, lack of access to clean water resources is one of the greatest environmental threats. In industrial countries, one of the major threats is air pollution. Global warming, caused by the emission of greenhouse gases, is another environmental security issue. Personal security – Personal security aims to protect people from physical violence, whether from the state or external states, from violent individuals and sub-state actors, from domestic abuse, or from predatory adults. For many people, the greatest source of anxiety is crime, particularly violent crime. Community security – Community security aims to protect people from the loss of traditional relationships and values and from sectarian and ethnic violence. Traditional communities, particularly minority ethnic groups are often threatened. About half of the world's states have experienced some inter-ethnic strife. The United Nations declared 1993 the Year of Indigenous People to highlight the continuing vulnerability of the 300 million Aboriginal people in 70 countries as they face a widening spiral of violence. Political security – Political security is concerned with whether people live in a society that honors their basic human rights. According to a survey conducted by Amnesty International, political repression, systematic torture, ill-treatment, or disappearance was still practised in 110 countries. Human rights violations are most frequent during periods of political unrest. Along with repressing individuals and groups, governments may try to exercise control over ideas and information.Oz Hassan (2015) Political security: From 1990 to the Arab Spring https://www.tandfonline.com/doi/full/10.1080/13569775.2014.993907].

Since then, human security has been receiving more attention from key global development institutions, such as the World Bank. Tadjbakhsh, among others, traces the evolution of human security in international organizations, concluding that the concept has been manipulated and transformed considerably since 1994 to fit organizational interests.

Freedom from Fear vs Freedom from Want and beyond In an ideal world, each of the UNDP's seven categories of threats (and perhaps others as a broader discussion might prioritize) would receive adequate global attention and resources. Yet attempts to implement this human security agenda have led to the emergence of two major schools of thought on how to best practice human security – '"Freedom from Fear"' and '"Freedom from Want"'. While the UNDP 1994 report originally argued that human security requires attention to both freedom from fear and freedom from want, divisions have gradually emerged over the proper scope of that protection (e.g. over what threats individuals should be protected from) and over the appropriate mechanisms for responding to these threats.

Freedom from Fear – This school seeks to limit the practice of Human Security to protecting individuals from violent conflicts while recognizing that these violent threats are strongly associated with poverty, lack of state capacity and other forms of inequities. This approach argues that limiting the focus to violence is a realistic and manageable approach towards Human Security. Emergency assistance, conflict prevention and resolution, and peace-building are the main concerns of this approach. Canada, for example, was a critical player in the efforts to ban landmines and has incorporated the "Freedom from Fear" agenda as a primary component in its own foreign policy. However, whether such a “narrow” approach can truly serve its purpose in guaranteeing more fruitful results remains to be an issue. For instance, the conflicts in Darfur are often used in questioning the effectiveness of the "Responsibility to Protect”, a key component of the Freedom from Fear agenda. Freedom from Want – The school advocates a holistic approach in achieving human security and argues that the threat agenda should be broadened to include hunger, disease and natural disasters because they are inseparable concepts in addressing the root of human insecurity and they kill far more people than war, genocide and terrorism combined. Different from "Freedom from Fear", it expands the focus beyond violence with emphasis on development and security goals.

Despite their differences, these two approaches to human security can be considered complementary rather than contradictory. Expressions to this effect include:

Franklin D. Roosevelt's famous Four Freedoms speech of 1941, in which "Freedom from Want" is characterized as the third and "Freedom from Fear" is the fourth such fundamental, universal, freedom. The Government of Japan considers Freedom from Fear and Freedom from Want to be equal in developing Japan's foreign policy. Moreover, the UNDP 1994 called for the world's attention to both agendas.
