SDG 2 - Zero hunger

Zero Hunger

End hunger, achieve food security and improved nutrition and promote sustainable agriculture

It is time to rethink how we grow, share and consume our food.

If done right, agriculture, forestry and fisheries can provide nutritious food for all and generate decent incomes, while supporting people-centred rural development and protecting the environment.

Right now, our soils, freshwater, oceans, forests and biodiversity are being rapidly degraded. Climate change is putting even more pressure on the resources we depend on, increasing risks associated with disasters such as droughts and floods. Many rural women and men can no longer make ends meet on their land, forcing them to migrate to cities in search of opportunities.

A profound change of the global food and agriculture system is needed if we are to nourish today’s 815 million hungry and the additional 2 billion people expected by 2050.

The food and agriculture sector offers key solutions for development, and is central for hunger and poverty eradication.

Facts and Figures

Hunger

  •     Globally, one in nine people in the world today (815 million) are undernourished
  •     The majority of the world’s hungry people live in developing countries, where 12.9 per cent of the population is undernourished.
  •     Asia is the continent with the hungriest people – two thirds of the total. The percentage in southern Asia has fallen in recent years but in western Asia it has increased slightly.
  •     Southern Asia faces the greatest hunger burden, with about 281 million undernourished people. In sub-Saharan Africa, projections for the 2014-2016 period indicate a rate of undernourishment of almost 23 per cent.
  •     Poor nutrition causes nearly half (45 per cent) of deaths in children under five – 3.1 million children each year.
  •     One in four of the world’s children suffer stunted growth. In developing countries, the proportion can rise to one in three.
  •     66 million primary school-age children attend classes hungry across the developing world, with 23 million in Africa alone.

Food security

  •     Agriculture is the single largest employer in the world, providing livelihoods for 40 per cent of today’s global population. It is the largest source of income and jobs for poor rural households.
  •     500 million small farms worldwide, most still rainfed, provide up to 80 per cent of food consumed in a large part of the developing world. Investing in smallholder women and men is an important way to increase food security and nutrition for the poorest, as well as food production for local and global markets.
  •     Since the 1900s, some 75 per cent of crop diversity has been lost from farmers’ fields. Better use of agricultural biodiversity can contribute to more nutritious diets, enhanced livelihoods for farming communities and more resilient and sustainable farming systems.
  •     If women farmers had the same access to resources as men, the number of hungry in the world could be reduced by up to 150 million.
  •     4 billion people have no access to electricity worldwide – most of whom live in rural areas of the developing world. Energy poverty in many regions is a fundamental barrier to reducing hunger and ensuring that the world can produce enough food to meet future demand.

Space-based Technologies for SDG 2

Soil conditions, water availability, weather extremes and climate changes can affect agriculture and food security. Space technologies provide weather data for agricultural planning, helping to boost productivity and mitigate the effects of food shortages.

Interview with Dr. Pietro Campana

Dr. Pietro Campana studied environmental engineering with a focus on fluid dynamics, hydrology, and water resource management, before undertaking a PhD on solar irrigation systems. He is working on the water-food-energy nexus and is currently evaluating the first agrivoltaic system (a photovoltaic system that allows the combination of both electricity production and crop production on the same land to increase the land use efficiency) in Sweden. He constantly strives to work on something that can make a difference to people’s lives and finds developing tools and services that can solve water issues very exciting. He believes that to address the nexus challenges, we need novel technologies and more research and development funding.

Use of space-based technology to search for alternate sources of water in Tharparkar

In Pakistan’s southern province, Sindh, lies the world’s only fertile desert in the world. The Tharparkar Desert stretches till the southeastern parts of Punjab, joining the Cholistan Desert. Tharparkar District is the largest of 29 districts in Sindh. According to Integrated Water Resource Management Practices to Alleviate Poverty – A Model of Desert Development in Tharparkar, Pakistan, the Thar is, people of Thar, have their livelihoods dependent on 'rainfall and livestock rearing, which is critical to household food security.'

Water management in local communities led by women

When we think about geospatial technology, many of us imagine satellites for Earth observation and navigation, drones, and complex sensors used to collect information from the terrestrial surface. We also believe that most of the people capable of developing applications using geospatial data should hold a science-related Master or Ph.D. degree. The previous statement could not be further from the truth. Advances in technology have made access to geospatial technology possible for everybody.  

Making Irrigation Decisions from Space: Utilizing a New Thermal Remote Sensing Satellite to Protect Food Security

Have you ever questioned if there would be enough food at the store for everyone in your community? If you frequent a grocery store or market, probably not. Every Sunday I go to the grocery store with a list of foods I’ll need for the week and no contingency plan for what to do if there isn’t enough. If something is out of stock, I’ll just go to the next grocery store down the road. We take it for granted that certain foods will always be available for us to purchase. However, many people do not have the luxury of a reliable food source.

Why space gardening should come down to Earth

When you think about agriculture, you probably imagine a few basic things in your mind. Huge stretches of flat land, massive harvesting machines, the heat on your skin from sunlight and, perhaps most importantly, soil. This image in your mind is a common one. Humans have been tilling, seeding, and farming land since the dawn of civilization, and modern industrial farm techniques tend to dominate our conception of agriculture. 

Pourquoi Devrions-Nous Utiliser le Jardinage de l'Espace sur Terre

Merci à Martin Sarret d'avoir traduit cet article volontairement.

Les caractéristiques élémentaires de l´agriculture nous viennent tous assez facilement à l´esprit. De larges étendues de terrain, d'imposantes machines de récolte, la chaleur du soleil sur la peau et, peut-être le plus important, la terre. Cette image mentale est finalement assez logique. L´humanité laboure, ensemence et cultive la terre depuis la nuit des temps, et les techniques agricoles industrielles modernes ont tendance à s'accaparer notre imaginaire sur l'agriculture.

Mapping and Monitoring Irrigated Agriculture from Space

Irrigation illustrates a major dilemma of agriculture: On the one hand, a growing world population demands more food and biomass (for example for energy production). On the other hand, natural resources such as water are only available in limited quantities and excessive use often leads to the degradation of ecosystems, which in turn has adverse effects on agricultural production and local livelihoods.

Water Accounting +

Water problems around the world are increasing; however, information useful for decision makers within the water sector and related to the water sector seems to be decreasing. Solving water problems requires information from many disciplines, and the physical accounts (describing sources and uses of water) are the most important foundation. The information has to be coherent and harmonized in order to provide an integrated picture useful for the assessment of the problems.
