The problems related to the process of industrialisation such as biodiversity depletion, climate change and a worsening of health and living conditions, especially but not only in developing countries, intensify. Therefore, there is an increasing need to search for integrated solutions to make development more sustainable. The United Nations has acknowledged the problem and approved the “2030 Agenda for Sustainable Development”. On 1st January 2016, the 17 Sustainable Development Goals (SDGs) of the Agenda officially came into force. These goals cover the three dimensions of sustainable development: economic growth, social inclusion and environmental protection. The Encyclopedia of the UN Sustainable Development Goals comprehensively addresses the SDGs in an integrated way. It encompasses 17 volumes, each devoted to one of the 17 SDGs. This volume addresses SDG 2, namely "End hunger, achieve food security and improved nutrition and promote sustainable agriculture" and contains the description of a range of related terms, to allow for a better understanding and foster knowledge. Our planet produces enough food to feed everyone. Malnutrition and hunger are the result of inappropriate food production processes, bad governance and injustice. SDG 2 seeks to guarantee quality and nutritious food to ensure healthy life by adopting a holistic approach that involves various actions targeting different actors, technologies, policies and programs. These initiatives have to face challenges coming from extensive environmental degradation, loss of biodiversity and the interrelated effects of climate change.Concretely, the defined targets are:End hunger and ensure access by all people, in particular the poor and people in vulnerable situations, including infants, to safe, nutritious and sufficient food all year roundEnd all forms of malnutrition, including achieving the internationally agreed targets on stunting and wasting in children under 5 years of age, and address the nutritional needs of adolescent girls, pregnant and lactating women and older personsDouble the agricultural productivity and incomes of small-scale food producers, in particular women, indigenous peoples, family farmers, pastoralists and fishers, including through secure and equal access to land, other productive resources and inputs, knowledge, financial services, markets and opportunities for value addition and non-farm employmentEnsure sustainable food production systems and implement resilient agricultural practices that increase productivity and production, that help maintain ecosystems, that strengthen capacity for adaptation to climate change, extreme weather, drought, flooding and other disasters and that progressively improve land and soil qualityMaintain the genetic diversity of seeds, cultivated plants and farmedand domesticated animals and their related wild species, including through soundly managed and diversified seed and plant banks at the national, regional and international levels, and promote access to and fair and equitable sharing of benefits arising from the utilization of genetic resources and associated traditional knowledge, as internationally agreedIncrease investment, including through enhanced international cooperation, in rural infrastructure, agricultural research and extension services, technology development and plant and livestock gene banks in order to enhance agricultural productive capacity in developing countries, in particular least developed countriesCorrect and prevent trade restrictions and distortions in world agricultural markets, including through the parallel elimination of all forms of agricultural export subsidies and all export measures with equivalent effect, in accordance with the mandate of the Doha Development RoundAdopt measures to ensure the proper functioning of food commodity markets and their derivatives and facilitate timely access to market information, including on food reserves, in order to help limit extreme food price volatilityEditorial BoardDatu Buyung Agusdinata, Mohammad Sadegh Allahyari, Usama Awan, Nerise Johnson, Paschal Arsein Mugabe, Vincent Onguso Oeba, Tony Wall
