Abstract

A 70% increase in food production is required over the next four decades to feed an ever-increasing population. The inherent difficulties in achieving this unprecedented increase are exacerbated by the yield-depressing consequences of climate change and variations and by the pressures on food supply by other competing demographic and socioeconomic demands. With the dwindling or stagnant agricultural land and water resources, the sought-after increases will therefore be attained mainly through the enhancement of crop productivity under eco-efficient crop production systems. ‘Smart’ crop varieties that yield more with fewer inputs will be pivotal to success. Plant breeding must be re-oriented in order to generate these ‘smart’ crop varieties. This paper highlights some of the scientific and technological tools that ought to be the staple of all breeding programs. We also make the case that plant breeding must be enabled by adequate policies, including those that spur innovation and investments. To arrest and reverse the worrisome trend of declining capacities for crop improvement, a new generation of plant breeders must also be trained. Equally important, winning partnerships, including public-private sector synergies, are needed for 21st century plant breeding to bear fruits. We also urge the adoption of the continuum approach to the management of plant genetic resources for food and agriculture as means to improved cohesion of the components of its value chain. Compellingly also, the National Agricultural Research and Extension System of developing countries require comprehensive overhauling and strengthening as crop improvement and other interventions require a sustained platform to be effective. The development of a suite of actionable policy interventions to be packaged for assisting countries in developing result-oriented breeding programs is also called for.

Global food security could be imperilled by the combined pressures from the effects of continually evolving climatic conditions, demographics and other socio-economic factors, the demands of the livestock, bioenergy and fibre industries for food-based substrates, the static or decreasing availability of natural resources for agriculture and the impracticality of increased use of economically and environmentally costly agricultural inputs. The optimal harnessing of plant genetic resources for food and agriculture (PGRFA) in manners that translate their repertoire of hidden potentials into significantly enhanced crop productivities has been severally identified as crucial to achieving the required considerably significant increases in food production. The scope of the problems and the plausible means for addressing them compel the devising of novel and more efficient ways for deploying PGRFA in need-based crop improvement programmes. We posit a continuum approach to the management of PGRFA which links seamlessly the effective conservation and access to PGRFA through their use in developing superior and resilient crop varieties to the provision of their high-quality seeds and planting materials to the growers. To achieve the mainstreaming of this paradigm, we propose the institutionalization of overarching national PGRFA strategies that prescribe result-oriented action plans spanning above three components of the management of PGRFA for a country's priority crops. We also describe the strategy as a means for identifying and assigning responsibilities to critical stakeholders and providing for the governance of all aspects of PGRFA activities over specific time frames. Steps to developing and adopting a national PGRFA strategy are also suggested.

A global survey was conducted among a wide range of stakeholders to gain insight into the state of on-farm management (OFM) as a strategy for enhancing the conservation and sustainable use of plant genetic resources for food and agriculture (PGRFA). The results show that OFM is not considered a priority in national PGRFA programmes (NPGRPs), and that OFM practitioners and their organizations are not always aware of, or involved in, NPGRPs. The survey also highlighted the lack of awareness, understanding and collaboration between OFM practitioners and the managers and policy-makers associated with NPGRPs. The outcome of the analysis supports a hypothesis that OFM is, to a large extent, supported by stakeholders who are not directly engaged in the conservation and use of PGRFA, and therefore not associated with NPGRPs. This should be taken into consideration when seeking to improve the performance and impact of national programmes, and their commitment to safeguard PGRFA and contribute to food security, poverty alleviation and sustainable agriculture.

Millions of farmers depend on the use of local crops and varieties for their food and livelihood. These resources constitute a reservoir of alternative traits and characteristics, which allow us to diversify crops, foods and farming methods and provide material for targeted plant breeding. Still, many countries lag behind in providing support to farming communities for the maintenance and use of plant genetic resources for food and agriculture (PGRFA). A global survey was conducted among a wide range of stakeholders to gain insights into the state of on-farm management (OFM) as a strategy for enhancing the maintenance and sustainable use of PGRFA. The survey showed that a wide range of stakeholders provide de facto support to OFM and that the practices they consider critical are focused on building capabilities in local communities. This supports the fact that the management of crop diversity on farm can be promoted in a variety of ways, depending on the specific context, and that local solutions are needed to successfully support OFM. Partnerships and networks should be considered as one of the critical means to promote OFM, as they involve a diversity of stakeholders working towards common goals. The survey further showed that many respondents currently contribute to existing networks relevant to OFM, but that these networks are mainly nationally or internationally oriented and might therefore exclude crucial local stakeholders, such as community-based organizations. Therefore, mechanisms should be put in place to strengthen the collaboration between stakeholders and networks, especially at the local level.

Any diet that is qualified as a 'sustainable diet' should be nutritionally adequate, affordable, safe, healthy and culturally acceptable. In optimizing natural and human resources, provision of sustainable diets requires strong partnerships among the stakeholders engaged in production, delivery and disposal of food. Such partnerships have to be based on value proposition, trust and commitment. This chapter will explore the role partnerships play in developing a pathway for sustainable diets, in particular in the context of the common vision of sustainable food and agriculture principles offered by the Food and Agriculture Organization (FAO). The chapter will also focus on ways and means to strengthen sustainable diets by increasing collaboration among governments and non-state actors such as civil society, farmers' organizations, the private sector, academia and research institutions. It will discuss the current style and forms of partnerships in practice with some examples from FAO experience in coordination and strengthening of strategic partnerships, to share knowledge and resources and develop capacities among countries in support of the sustainable development goals.
