With the 2011 and 2012 food crises in the Horn of Africa and the Sahel, calls for urgent action and sustainable solutions to food insecurity in Africa have intensified. While many factors, like rising commodity prices, have been contributing factors, land degradation stands out as a main catalyst. In the search for a solution, indigenous farming techniques may offer some quick wins.

The 2011-12 West African food crisis led to riots in Senegal and Burkina Faso as well as food insecurity for millions of rural and urban poor across the region. The crisis emerged from a number of factors, including instability in northern Mali, increases in global food prices, and low rainfall in the 2010-2011 and 2011-2012 growing seasons. Many countries in the region are now reassessing and expanding domestic agricultural capabilities. At the top of the agenda for Senegal, a democratic republic on track to reach many Millennium Development Goals, is reducing youth unemployment and increasing domestic agricultural capacity.

The disempowerment of women and girls is the single biggest driver of inequality today, said Helen Clark, administrator of the UN Development Program, during a plenary on the final day here at the Women Deliver conference in Kuala Lumpur, where more than 4,500 people from 149 countries and 2,200 organizations gathered to discuss women’s health, equity, and international development.

A staggering amount of development dollars – one in three, in fact – are lost due to natural disasters and crises. Certain communities are less affected than others by such disasters; they are more resilient. Knowing where vulnerability and strength exist and how to bolster them could help avoid these losses. Yet, today, very little data exists to help development practitioners understand which adaptive capacities are lagging in a given community.

A little over a decade ago when I first became interested in the subject of environmental security, it took me ages to understand what I have since been eager to stress: environmental security is not a concept but rather a debate.

In the Philippines, there are health and development programs that specifically target children, senior citizens, and adults, said Joan Castro, but adolescents are underserved. Nineteen percent of the population is between the ages of 15 and 19, but “they can’t even go to health centers to get the family planning commodities [they desire],” she said. [Video Below]

Today, the Sahara Desert is a vast, nearly lifeless expanse of sand and rock. But ancient cave paintings tell of a time when it was fertile grassland and bands of human hunters chased aurochs and antelope.
