Int. J. Environ. Res. Public Health 2011, 8 369 Countries should identify context-dependent solutions, which integrate technical prevention and treatment-based interventions with wider efforts to enhance food security and diet diversity. It will be critical to ensure that food and nutrition system approaches are embedded centrally in poverty reduction or development plans or as stand-alone initiatives linked to the overall development vision for countries moving forward. There is plenty of evidence to suggest that in the absence of clear policy, rapid gains are much more limited. But financial support is a must. In countries where resources are scarce, international development assistance will remain an important, temporary solution. Strong evidence and robust tools are available to leverage agriculture that ensures positive nutritional outcomes. Knowledge and expertise to address food security and reduce poverty by leveraging existing food systems are available as well. It is now time to utilize these tools, evidence and knowledge, and to support governments to invest in systems in order to address these issues at global scale. Communities also play a major role. Community and household food and nutrition security depends on underlying social, economic and institutional factors, which ultimately affect the quantity, quality and affordability of food as well as nutrition, health and wellbeing. By giving communities the tools and knowledge to make choices, a resilient food and nutrition system can be developed that ensures environmental integrity, economic self-reliance and social wellbeing. 6. Conclusions A new focus must be undertaken that addresses the longer-term determinants of nutrition insecurity and hidden hunger. There must be an emphasis on interventions that address food and nutrition security as part of a wider multi-sector strategy tailored to diverse conditions of major agroecological, socioeconomic and epidemiological situations. While underlying determinants of undernutrition have been well understood for decades, the design, testing and scaling of more holistic multi-sectoral packages that combine child care and disease control interventions with food system and livelihood-based approaches has been limited in their development and implementation.
