War in Tigray has destroyed decades-long vegetation restoration efforts.
When the Ethiopian and Eritrean defense forces, alongside Amhara regional forces, invaded Tigray in November 2020, the aftermath resulted in one of the world’s worst humanitarian crises.
One overlooked element of the destruction, the war has degraded the region’s forest resources on a massive scale. Shelling from heavy artillery has brought about the destruction of forests and other natural resource bases throughout Tigray. In addition, all nursery types and a forest seed centers were plundered and destroyed by the invading forces.
According to the Tigray Development Association’s (TDA) 2022 report, owing to the war, only 4.5 million seedlings have been planted in Tigray so far in 2022.
The TDA also reports that clean energy sources such as electricity lines that connect Tigray have been purposely curtailed by federal authorities, 80,000 home solar systems with a capacity of 80 to 150 watts were pillaged, and 3,500 tons of biogases have been burned by the invaders.
As a result, Tigrayans are forced to use firewood from nearby exclosures and natural forests despite the fact that local bylaws restrict the cutting of trees from such forest resources.
The energy crisis in Tigray has put pressure on trees and shrubs, causing vegetation decline to become visible. If these trends continue, the ability of forest ecosystems to mitigate climate change and provide basic needs such as food, water, timber, and fuelwood will diminish.
Tigray is an arid and semi-arid region located in northern Ethiopia. In this moisture-stressed environment, agriculture constitutes the backbone of the region’s economy and workforce.
In the 1970s and 80s, Tigray was plagued by armed conflicts and recurrent droughts which led to widespread land degradation and unsustainable natural resource management (Fig 2). To this day, these degraded farmlands constrain agricultural production and labor productivity.
In addition, as Tigray’s vegetation cover was less than three percent, fuelwood for energy and herbaceous biomass for animal feed and bee forage were negatively affected. Forest use for human consumption, such as for farm equipment and construction material, was insufficient. Furthermore, in the 1980s, alternative clean energy technologies that help to limit biomass demand for cooking were also lacking.
Owing to limited soil mulch and vegetation cover, intensive downpours have resulted in high levels of surface runoff and low water infiltration capacity.
As a result, severe soil erosion rates ranging from 19 to 29 tons per hectare (ha) have occurred, causing the formation of wide and deep gullies. Low crop productivity appeared to be less than one ton per ha in the degraded farmlands, leading rising poverty levels.
Over the years, the federal government of Ethiopia, the government of Tigray, and non-governmental organizations (NGOs) have made a concerted effort to redress the interlinked problems of land degradation.
Conservation-based agricultural development policies, community bylaws, and high political and community engagement have contributed to the effective implementation of degraded land restoration programs in Tigray.
Ranging from twenty to forty days every year, a massive community free labor campaign for soil and water conservation works has been mobilized during the last three decades.
According to a 2020 report by the Tigray bureau of agriculture and natural resources, about 30 percent of the total degraded lands had been treated with various types of soil and water conservation structures, leading to livelihoods and environmental improvements.
In addition, about 302,719 ha of degraded communal lands had been restored through area exclosures and around 196,416 ha of land was developed through plantation programs. In addition, more than 1,083 forest guards were mobilized to protect 260,720 ha of natural forests and 288,156 ha of state forests from human and animal interference.

Aimed at rapid forest restoration and re-greening, the government, NGOs, and private companies have established 237 government nurseries, 71 community nurseries, and more than 5,000 private nurseries designed to recover forest resources.
These nurseries had been producing and distributing 100 to 120 million quality indigenous and exotic tree seedlings every year. A total of 459,700,000 tree seedlings were planted from 2016 to 2020, with a 56 percent (257,432,000) survival rate, covering 237,750 ha of land.
For swift forest restoration, a seed center was also established in Mekelle with the mandate to collect, certify, and deliver quality seeds to various nursery sites in Tigray.
Through these concerted efforts, vegetation cover in Tigray increased from 3 to 16.8 percent, soil erosion rates decreased by greater than 50 percent (29 to 14 ton per ha) over a 30-year period, and groundwater tables enhanced significantly. For example, a case study conducted in Abraha We Atsbaha revealed that the average water depths of the shallow wells had increased from three to fifteen meters.
Moreover, crop productivity has increased from less than 1 to 1.9 tons per ha, thereby reducing the poverty level from 48 to 29 percent over the last thirty years.
These combined efforts had turned Tigray into an environmental success story. As a result, Tigray was recognized at the 2012 UN Conference on Sustainable Development for its tireless efforts to devise innovative hunger solutions.
Tigray was also a gold medal winner at the World Future Council in 2017 for best policy in combating desertification and land degradation.
As Tigrayans lack other energy sources for cooking, a sustainable harvest of fuel wood is required to ensure the forest’s long-term survival.
Sustainable use of forest resources should include the following actions:
- Use fuel wood from trees that have fast regrowth ability from privately and community owned forest resources, such as Eucalyptus, acacia saligna, and ficus.
- Harvest fuelwood through pruning from multi-stemmed trees, such as acacia etbaica.
- Use available invasive tree species, such as prosopis juliflora and lantana camara, for charcoal preparation and firewood collection.
- Introduce new and maintain available clean energy sources such as home solar systems, biogas, and improved cooking biomass stoves.
- As ample seedlings cannot be raised for this planting season, people are advised to use vegetative propagation techniques through branch cutting and plant multipurpose trees in degraded landscapes, such as ficus thonningii.
- A massive awareness campaign through printed and local media is required, as other communication and forestry extension packages such as on job training, field visits, and experience sharing, internet-based monitoring, evaluation, and backstopping techniques are currently non-existent in Tigray.
- Forest protection using scouts and wise management is necessary to sustainably utilize the wood collected from exclosures and natural forests.
- Strong commitment of government, local administration, and the community in general is needed to save and protect the forest resources of Tigray.
The siege being imposed on Tigray by the Ethiopian government and its allies has now been ongoing for more than six hundred days. The degradation of forests is among the humanitarian crises caused by this inhumane tactic.
Tigray’s government and foreign donors must include the region’s forestry sector in any future recovery and development plans. Significant funds are needed to restore the degraded environment.
Reversing the trend of deforestation and forest degradation requires institutional restoration. Pillaged forest extension systems, nursery sites, seed centers, and clean energy sources such as electricity, home solar systems, and biogas should be restored in Tigray.
External actors must put pressure on the Ethiopian government and its allies to end the blockade and siege, and restore social services in Tigray, including electricity and forest institutions. They should also allocate restoration funds to reverse the forest degradation in Tigray caused by war.
Pressing action is required to rehabilitate degraded land and turn Tigray into a success story.
