Agriculture development, food security and nutrition A/RES/73/253 23. Remains deeply concerned about the recurring food insecurity and malnutrition in different regions of the world and their ongoing negative impact on health and nutrition, especially in sub-Saharan Africa and South and West Asia, and in this regard underlines the urgent need for joint efforts at all levels to respond to the situation in a coherent and effective manner; 24. Recognizes the important role of indigenous peoples and local communities, small-scale farmers, family farmers, livestock farmers, small-scale fishers and fish workers and their traditional knowledge and seed supply systems, as well the important role of new technologies in the conservation of biodiversity and in aiming to ensure food security and improved nutrition; 25. Stresses the importance of the application of science, technology and innovation and related knowledge management and communications systems in ensuring food security by 2030, and encourages the adoption of the most advanced and appropriate information technology, such as the Internet, mobile platforms, meteorology, big data and cloud computing, in agriculture systems in order to support the efforts of smallholder and family farmers to increase their resilience, productivity and incomes and include them in the development of research and innovation agendas; 26. Emphasizes the need to revitalize the agriculture sector, promote rural development and aim for ensuring food security and nutrition, notably in developing countries, in a sustainable manner, which will contribute to achieving the Sustainable Development Goals, and underlines the importance of taking the necessary actions to better address the needs of rural communities by, inter alia, enhancing access for agricultural producers, in particular small producers, women, youth, indigenous peoples and local communities, persons with disabilities and older persons, in conflict and post-conflict situations, to credit and other financial services, markets, secure land tenure, health-care services, social services, education, training, knowledge and appropriate and affordable technologies, including for development of local crops, efficient irrigation, reuse of treated wastewater and water harvesting and storage; 27. Recognizes that, by 2050, the world urban population is expected to nearly double, making urbanization one of the most transformative trends of the twenty -first century, underscoring the growing need to take action to fight hunger and malnutrition among the urban poor through promoting the integration of the food security and nutrition needs of urban residents, in particular the urban poor, in urban and territorial planning, to end hunger and malnutrition, promoting the coordination of sustainable food security and agriculture policies across urban, peri-urban and rural areas to facilitate the production, storage, transport and marketing of food to consumers in adequate and affordable ways, to reduce food losses and to prevent and reuse food waste, and promoting the coordination of food policies with energy, water, health, transport and waste and other policies in urban areas to maximize efficiencies and minimize waste; 28. Reaffirms the need to strive for a comprehensive twin-track approach to food security and nutrition that consists of direct action to immediately tackle hunger for the most vulnerable and medium- and long-term sustainable agriculture, food security and nutrition and rural development programmes to eliminate the root causes of hunger and poverty, including through the progressive realization of the right to adequate food in the context of national food security; 29. Also reaffirms the need to promote a significant expansion of research on food, nutrition and agriculture, extension services, training and education, and of funding for such research from all sources, to improve agricultural productivity and sustainability in order to strengthen agriculture as a key sector, to promote development and to build up resilience to support better recovery from crisis, 18-22634 11/13
