Water Security is National Security

Water resources and how they are managed impact almost all aspects of society and the economy, in particular health, food production and security, domestic water supply and sanitation, energy, industry, and the functioning of ecosystems. Under present climate variability, water stress is already high, particularly in many developing countries, and climate change adds even more urgency for action. Without improved water resources management, the progress towards poverty reduction targets, the Millennium Development Goals, and sustainable development in all its economic, social and environ- mental dimensions, will be jeopardized.

Let's Quit This Most Dangerous Game with Drought

On a recent visit to Niger, I met a woman in Batodi village with some very bold claims. Fifteen years ago, she and her fellow women would travel a day's journey to fetch water.

Today, they fetch it from a local well, having turned the situation around by rehabilitating their badly degraded land using traditional practices. In that period, the water level has “jumped up” by 14 meters. Moreover, the village had withstood the severe food and water challenges others in many parts of Niger suffered during recent droughts.

The researcher who had invited me backed the claims that the water table had risen from a depth of below 18 meters to about 4 meters below the ground. That was precisely why he had invited me to the field; to witness – contrary to claims otherwise – that it is possible to restore the health of even badly degraded land.

On 17 June, we unveil the winners of the 2013 Land for Life Award from 137 submissions worldwide. At the national level, Eritrea, Hungary, Kenya, Portugal and Thailand unveil their first Drylands Champions to recognize the local heroes making laudable steps in the fight against desertification and drought.

These kinds of stories, from the ground, inspire me to advocate unceasingly for policies in favor of investments to strengthen both sustainable land use practices and drought resilience. Grabbing more fragile lands to meet growing food demand is neither the answer nor is improving relief delivery the ultimate solution.

Rather, we must boldly move to a land-degradation neutral world where clearing new land is not an option, and, where it is inevitable, our collective target becomes offsetting such action by rehabilitating degraded land at the same pace and in the same ecosystem.

Political contestations over whether a land-degradation neutral world is possible should not prevail for lack of generalizable scientific claims to demonstrate it. Until massive investments in small pilot projects such as these by communities fail, their viability is not in question; the status quo is.

The achievements in Batodi, the submissions to the Land for Life Award and the work of the Drylands Champions affirm the claims of the recent report, A Dangerous Delay – The cost of late response to early warning in the 2011 drought in the Horn of Africa, that “the response to drought was too little too late, representing a systemic failure of the international system.”

Indeed, the international community has been here before; in the mid-1970s, with the Sahel drought disaster, in the mid-1980s with the drought and famine disaster in Ethiopia and, most recently, in 2011, with the tragedy in the Horn of Africa.

But the best evidence that we, as an international community, are playing the world's most dangerous game with drought lies in the fact that only one country in the world – Australia – has a comprehensive national drought policy.

There are more reasons for concern.

Drought affects more lives than any other disaster, yet unlike most disasters, it has a slow onset. And not only has every region in the world experienced more severe droughts in recent times, but droughts are set to increase in intensity, in spread and in frequency due to climate change.

About a billion people, among them people living in the arid and semi-arid parts of the world, have access to little or no renewable water resources. With the climate change scenarios, that estimate shoots to about half the world's population living in areas of high water stress by 2030.

Neither desertification nor droughts are fated, but the path to change is through a radical transformation in our view of the land and attitude towards drought.

Land is a strategic natural asset for our future sustainability. So let us give life to the aspiration of a land-degradation neutral world by setting a target date for its achievement as part of the Sustainable Development Goals to be agreed by 2015. We should follow in the steps of Africa. At its Summit last month it declared this part of its future agenda and called on the global community to do the same.

Senegal begins planting the Great Green Wall against climate change



Africa's proposed 4,000-mile wall of trees stretching from Senegal to Djibouti is designed to stop encroaching desertification.

Senegal's capitol city Dakar sticks out into the Atlantic Ocean on a peninsula. It's at least a thousand miles to the Sahara desert yet the air today is so thick with sand that the tops of buildings disappear in a sandy haze.

It's the worst sand storm in a year and people here are worried thatclimate change will cause these events to be more common. Seasons are shifting across the region. In Senegal the rainy season used to start in July or August but now it doesn't start until September. Decreased rain - along with over grazing of land - is causing an increase in deserts across the Sahel. Roughly 40 per cent of Africa is now affected by desertificationand according to the UN, two-thirds of Africa's arable land could be lost by 2025 if this trend continues.

Senegal is one of 11 countries in the Sahel region of Africa looking towards the same solution to the desertification problem: The Great Green Wall. The goal of the project is to plant a wall of trees, 4,300 miles long and 9 miles wide, across the African continent, from Senegal to Djibouti. African leaders hope the trees will trap the sands of the Sahara and halt the advance of the desert.

Papa Sarr is Technical Director for the Great Green Wall in Senegal: "We are convinced that once we start to plant the wall of trees dust will decrease in Dakar," he says.

Sarr sits in the passenger seat of a four-wheel drive on his way to Widou, a village he hopes will serve as a model for the Great Green Wall in Senegal. The paved roads of Dakar give way to red sand paths of the Shahel; a dry savanna transition zone between the equatorial jungles in the south and the Sahara to the north. Black and white goats meander in front of the truck and flat-topped acacia trees dot the sandy landscape. They are virtually the only vegetation in a region where the dry season can last up to 10 months.

Four hours northwest of Dakar, the village of Widou sits next to one section of Senegal's Great Green Wall. The acacia trees here are just four years old, waist high and thorny. The trees are surrounded by a firewall and a metal fence to keep out tree-eating goats. All of the trees were chosen carefully. Sarr says, "When we design a parcel we look at the local trees and see what can best grow there, we try to copy Nature."

Two million trees are planted in Senegal each year; but all of them must be planted during the short rainy season. Labourers plant acacia saplings in the sand along with animal manure for fertiliser. Sarr points to a three feet tall tree. "This one is Acacia nilotica. It produces Arabic gum used in local medicine and a fruit that can be eaten by animals." More
