Does climate change cause conflicts in the Sahel?

Tor Benjaminsen | 28 November 2016

An emerging narrative in international politics and media presentations points to global warming as a driver of conflict in the Sahel   ̶  but this narrative risks glossing over the real root causes, while potentially undermining long-term public engagement in climate change. Recent research on conflicts in Mali suggests that the existence of clear links between climate change and conflict is doubtful.

The conflict in Mali has its roots in history, but can also be seen as a product of current economic, ecological, political, security and geopolitical developments in the region.

The Sahel is often recognized as a hotspot of violent conflict, typically between farmers and pastoralists or between the state and armed groups. More recently, jihadist violence has reinforced this image, in particular by groups associated with ISIL and Al Qaeda in Mali, Boko Haram in Nigeria and Al-Shabaab in Somalia.

What is behind these conflicts? Most empirical research points to political and historical factors as root causes. However, as climate change becomes a leading global political issue, an emerging and increasingly powerful policy narrative presents global warming as a major driver of conflict. But how valid is this argument?

Examining the climate-conflict link  

Two elements underpin the climate-conflict narrative. First, it assumes global climate change leads to drought and desertification, which in turn leads to resource scarcity. Second, it suggests this resource scarcity causes migration   ̶ fuelling new conflicts, or triggering existing unrest bubbling below the surface.

But trends show more rainfall – not less

Since the Sahelian ecosystem largely depends on rainfall, global warming   ̶  if it reduces rainfall   ̶   may lead to desertification and resource scarcity in the long run. However, current rainfall trends and projections do not point to less rainfall: while some climate models support the idea that this region will become drier, most models actually suggest more abundant   ̶   but also possibly more delayed and concentrated   ̶   rainfall in the future.

In fact, since the drought years of the 1980s the Sahel has seen more rainfall. It has become greener again, not desertified.

Evidence linking resource scarcity and conflict is weak

Empirical evidence from international research also casts doubt on the second element of the climate-conflict narrative. Although a link between resource scarcity and conflict cannot be simply dismissed, most empirical results question its validity.

Rather, case studies in central parts of the Sahel indicate that conflicts have historical and political causes such as government officials seeking rent, as well as policies and legislation that marginalize pastoralists.

The example of Mali

One example comes from the dry parts of Africa where pastoralism and farming overlap as the main forms of land use, and where conflicts   ̶  large or small   ̶  are ongoing.

In Mali, farmer-herder conflicts are linked to the state’s pastoral and land tenure policies and legislation. These generally favour farmers and tend to lead to pastoralists being squeezed out of access to grazing land.

Three structural factors are key drivers of these conflicts:

  • agricultural encroachment that has obstructed free movement for herders and livestock;
  • opportunistic behaviour by farmers and herders who moved to fill a political vacuum left by the disintegration and withdrawal of services following the state’s decentralization policy;
  • corruption and rent seeking among government officials.

Pastoral marginalization was also at the root of the Tuareg rebellion that triggered Mali’s civil war in the 1990s and again in 2012. The drought of the 1970s and 1980s only played an indirect role in the rebellion: it led to the migration of young Tuareg men to Libya, where they were hired as soldiers and exposed to revolutionary ideas.

There was already a strong feeling among Mali’s Tuareg and nomads in general that they were being marginalized by state policies of modernization, and by policies that encourage fixed settlements. Then, embezzlement of drought relief funds by government officials in Bamako added to their anger  ̶ and young Tuareg in Algeria and Libya took up arms against the Malian state in 1990.

The rebellion would have likely taken place without the droughts of the 1970s and 1980s. It’s worth noting that the first Tuareg rebellion in Mali took place in 1963 following an unusually humid period.

Disputes are historical and political

Pastoralists are flexible and opportunistic in how they use their resources, meaning they can more easily adapt to climate variability than many other groups. But at the same time, state policies that favour settled agriculture in many countries in the Sahel at the expense of mobile and flexible livestock production undermine not only pastoralists’ access to land, but also livestock-keeping  ̶ which is still one of the region’s most important economic activities.

Empirical evidence from other parts of Africa, points to the same conclusion: the link between climate change and conflict is negligible. Droughts and floods may potentially escalate tensions, but evidence suggests that the root causes of land disputes are historical and political.

Climate change is without doubt one of the greatest global challenges of our time. But to suggest that it is responsible for causing conflict in the Sahel is overstretching its impact. This risks undermining long-term public engagement in climate change. It also risks overlooking the political factors that drive disputes. Glossing over the root causes could hinder efforts to find effective solutions to conflicts.
