What are rangelands?
When people of think of rangelands, their minds don’t usually go further than the images of shrubs or endless fields of dry grasslands. But beneath and above these vast spaces, life teems and even flourishes. At the recent session on the UN Decade on Ecosystems Restoration at the Global Landscapes Forum in Bonn on 23 June 2019, rangelands had a golden opportunity to take the stage alongside forests and other important ecosystems. In this post, we break down what rangelands are all about, the surprising economic and environmental roles they play and why they absolutely need our attention.
Though rangelands can include wetlands and forests, they are mostly found in drylands or arid and semi-arid lands, where rainfall is low and variable. They are areas where vegetation consists predominantly of grasses, grass-like plants, forbs or shrubs that are or can be grazed, and which are used as a natural ecosystem to raise grazing livestock and wildlife.
Why do they matter?
They’re ubiquitous. Nearly half the Earth’s land surface is classified as rangelands. Their health and productivity are directly linked to the livelihoods and cultures of more than 500 million people around the world, many of whom are indigenous peoples, such as pastoralists.
They have many uses. Rangelands are semi-natural ecosystems dependent on grazing by livestock or wildlife. They also provide watershed services that sustain surrounding communities and the incredible biodiversity of rangelands.
They are natural climate change mitigators. Rangelands are an important landscape to be considered next to forests, although most of the carbon is stored below ground in rangelands. In humid environments, rangelands may also sequester significant amounts of carbon in their soils. On top of that, their vast open spaces make them great sources for wind and solar power.
What are the challenges?
Land degradation is the major challenge faced by rangelands, resulting from, amongst others, a lack of grazing management plans, invasive species, and a lack of land tenure security. Signs of degradation include a shift in species composition, biodiversity loss, reduction in biomass production, less plant cover, low livestock productivity and soil erosion.
Lack of land tenure rights. Most formal legal systems in governments in developing countries do not recognize or guarantee customary tenure rights for pastoralists. This is threatening pastoralist traditional ways of life, where access to grazing land is vital for their livestock productivity and pastoralists ability to exercise their role as environmental stewards, shaping and maintaining landscapes while conserving biodiversity.
Information gaps remain. Though we know why rangelands are important, we still lack individual and aggregated data to support governments, private sector and local and international organizations to enable them to preserve and sustainably manage rangeland ecosystems. There remains the need to quantify and qualify:
Why include rangelands in the UN Decade on Ecosystems Restoration?
The UN Decade on Ecosystem Restoration, declared on 1 March this year by the UN General Assembly, aims to massively scale up the restoration of degraded and destroyed ecosystems as a proven measure to fight the climate crisis and enhance food security, water supply and biodiversity.
In Africa alone, millions of hectares of grazing land and rangeland are threatened with degradation – from the arid north, the semi-arid south, the Sudano-Sahelian countries to the drier parts of Cameroon, Ethiopia, Kenya and Nigeria. A decade committed to ecosystems restoration provides an opportunity for rangelands to be considered as one of the targeted landscapes. It also reinforces efforts made thus far to declare an International Year of Rangelands and Pastoralists.
Rangeland restoration will produce three types of benefits, that are interlinked and cannot be considered separately:
