Sustainable Farming Systems for Food and Nutrition Security

The 2015 Sustainable Development Goals and the UN Decade of Action on Nutrition call on all countries to end hunger and prevent malnutrition in all its forms by 2030. This is quite a challenge, and it is a challenge with sustainable agriculture and food systems at its very heart.

And the current situation doesn’t look good. The latest State of Food Security and Nutrition in the World report estimates that in 2016 the number of chronically undernourished people actually increased to 815 million (up from 777 million in 2015). The report identifies that the food security situation has particularly declined in parts of sub-Saharan Africa, South-Eastern, and Western Asia, and especially in situations of conflict as well as conflict combined with severe climatic events such as droughts and floods.

Sustainable Development Goal 2 also sets the world targets that agricultural productivity and the incomes of small-scale food producers should double by 2030. At the same time food production systems should be sustainable, reduce their impact on ecosystems and be resilient to environmental change. But here again we are facing major challenges. The latest evidence from advanced global crop models suggests, for example, that global yields of wheat, rice, maize, and soybean will decline substantially with the predicted increase in global temperatures in the coming years.

Recently, the Sustainable and Healthy Diets in India project led by the London School of Hygiene & Tropical Medicine calculated for the first time the greenhouse gas and water footprints of food production in India and estimated the dietary changes required to meet future declining groundwater availability. These are among the first research efforts in South Asia to quantify the links between environmental sustainability and food and nutrition security at a time when, because of rapid urbanisation, transitions in diets and increasing populations, the food system is under increasing pressure.

So what sustainable agriculture and food systems are there that can ensure food and nutrition security in the future for South Asia? The LANSA programme is working with local communities in India, Bangladesh, Pakistan, and Afghanistan to identify farming system interventions that address community nutritional inadequaciesreduce environmental impacts, and also increase resilience to environmental stressors. These are important first steps in the generation of novel evidence to help meet current and future agriculture and food system challenges.
But the challenges the world faces are likely to be very great. Are we happy that we as a community working in agriculture, food systems, public health, and policy are really doing enough to respond?
Let’s begin to answer this!

  1. This is a very relevant topic. What work has been done in Pakistan LANSA so far? What exactly is the scope of "Sustainability" in this?

  2. Am Lucy Morgan from Atlanta Georgia  i was suffering from genital herpes, oral herpes, shingles. Before I came in contact with dr. Kham It is no longer news that the Acquired immune deficiency syndrome Herpes Virus is increasing by the day, The fear is that many people living with the sickness are scared of saying it because of the stigma that comes along with it.I am bold enough among many others to state that there is now a potent cure to this sickness but many are unaware of it.I discovered that I was infected with the virus 3 months ago, after a medical check-up. My doctor told me and I was shocked, confused and felt like my world had crumbled. I was dying slowly due to the announcement of my medical practitioner but he assured me that I could live a normal life if I took my medications, In a bid to look for a lasting solution to my predicament, I sought for solutions from the voodoo world. I went online and searched for every powerful trado-medical practitioner that I could severe, because I heard that the African Voodoo Priests had a cure for Herpes syndrome. It was after a little time searching the web that I came across one Dr. Kham website who offered to help me, He gave me some steps to follow and I meticulously carried out all his instructions. Two days ago to be precise, I went back to the hospital to conduct another test and to my amazement, the results showed that " I am NEGATIVE" You can free yourself of this Herpes virus by consulting this great African Voodoo Priest via this EMAIL or]  WHATSAPP NUMBER +2348159922297, You can Also Visit his website to know more about him at >
