While on one side of the spectrum it means that availability of sufficient supplies at national and international levels, on the other side it is concerned with sufficient nutrition and human health. Comparing these definitions underscore the significant reconstruction of the underlying meanings on the policy and research analyses. The definitions are to this end analogous with the concept of security, as proposed by Wolfer (1952) and Baldwin (1997), who stated that security is achieved by preventing threats of any nature, whether health threats.
Importance of the Global Food Security Issues Global food security concept ensures protection against vulnerabilities to food security. Sunderland (2013) argues that the capability to ensure sufficient food security depends on the capability to identify the vulnerable nations or households. Baldwin (1997) defines vulnerability as the range of factors that position individuals at risk of experiencing food insecurity. The level of an individual or a community’s vulnerability is established through examining their exposure to the risk factors as well as their capability to coping with or withstanding the demanding situations.
Sunderland (2013) showed that once the risk factors for food security are identified, it becomes easier to identify the mitigation strategies against food security. Understanding the issues enable national governments to come up with coping strategies. According to Gustafson (2013), identifying the vulnerable communities or individuals is also a critical step towards assisting the individuals to cope with or withstand the stressful situations. In Sunderland’s (2013) view, identifying the vulnerable groups or individuals can be ensured through an appropriate proxy, for instance how poor a certain household is measured against an established poverty line or criterion.
In a study of India’s food security, Gustafson (2013) remarked that government policies such as those that affect the vulnerable groups have debilitating effect on food security, which could however be resolved by having a change in policies. Food security has an underlying role in ensuring trade reforms. According to FAO (2003), the correlation between food security and trade reforms offers a foundation for global trade negotiations in many developing countries. The global dimension is significant since the trade policies substantially affect the global food availability through production and importation.
The impact on food imports can be arbitrated through implication of the trade policy on a country’s earnings from foreign-exchange. On a different perspective, Johnson (2009) indicates that policies affect food security because of the link to expenditures and incomes. This is since any change made in the trade regime will directly affect the urban and rural incomes as well as access to employment. The government revenues will in turn be affected by the change in the degree of revenues earned from customs duty.
Using a similar perspective, FAO (2003) noted that the government revenues and national food availability may affect the level of household access to nutritious and sufficient food depending on the level of household incomes. Food security issues are also critical for making reforms in the agricultural sector. This is of significance to food security professionals and policymakers. FAO (2003) indicated that since food security largely depends on the agricultural sector of an economy, knowing the extent of food risks or climate changes often provide data for making reforms for food security.
In regards to trade globalisation, poor economies are often not well positioned to benefit from trade liberalisation despite having significantly impacted the income levels. Johnson (2009) pointed out that this is because of their inflexible structures of food production and trade within the agricultural sector. According to FAO (2003), such situations are often manifested by limited market access and the underdeveloped institutions in addition to poor reforms and strategies that can perpetuate favourable conditions.
