About SERC

SERC stands for Social & Environmental Reforestation Collaboration
 
 Planting Trees 
A large portion of the Dhofar Forest has disappeared due to overgrazing and climate change. We can stop this development by planting new trees and protecting them, enabling all living species to live and strive in harmony.
 
 Community Engagement 
One of the main pillars of the SERC project is community engagement and participation. It is all about working together along with nature and with people. Therefore, a lot of the activities undertaken during the project is about awareness creation as well as learning about trees – their role in the ecosystem; as carbon balancers, as drivers for fertile and healthy soil, as providers of shade and humidity and their link to the unique fog-harvesting eco-system of Dhofar. These activities include school visits, workshops for private and public entities as well as mere outings in the field engaging volunteers in trial plantations.
 

 Water-Saving Reforestation Piloted in Dhofar 

A. Background

Oman is a historically fertile country with Wadi’s and the remains of past forest witnessing of the riches that once existed and sustained a largely rural population. The local practices to manage scarce water resources in a highly efficient and socially equitable manner, under the name of Iflag, are world famous. However, most of the green lands disappeared over the years. Water tables have sunk and local lands are losing their ability to sustain agriculture, rural incomes, and jobs.

The last region to retain its natural beauty and associated richness is Dhofar, which benefits from the Khareef, a weather phenomenon with sustains a seasonal lush fog-forest. The summer mist and this forest are intervowen as a single ecosystem that brings huge value to locals from traditional food and local practices, as well as from modern tourism. However, over the past 45 years, some 75 percent of the previously forested area has disappeared (Hildebrant, 2007). Past efforts to halt this damaging trend were unsuccessful. Yet, unless effective countermeasures are worked out, the Khareef will weaken and disappear, and Dhofar be turned to barren, dead lands unable to support people or animals outside the urban area.

Separately, however, experience from around the world has demonstrated that green areas can be recovered through innovative plantation of trees through methods that do not consume water, i.e. do not use drip irrigation, but which economize water and help restore the strength of the soil (Hoff, 2013). Early practices and in Oman were unsuccessful, and it was thought that the dry, hot season was too demanding. Recent experience has proven differently, however, given the adoption of a comprehensive solution, planting with native trees, complementing the soil with natural fertilisers, and training locals for effective plantation and monitoring, trees can be planted, survive, bring the water back and lay the basis for restoration of long-gone eco-systems. The result will be the revival of local land value, employment and income opportunities for rural populations. As the soil thickens and regains natural microbic life, erosion stops, sand storms cease, and the ocean regains health as the highly damaging impact of sand blown into the seas is held up.

Against this backdrop, starting in the Spring 2019, SERC project, with support of BP and making use of land provided  by MECA under its administration in Dhofar, has initiated plantations in four areas in Dhofar. The scheme focuses on planting young native trees, saplings, in dry areas. It experiments with a combination of water-saving innovative technologies, without dependency on drip-irrigation, soil improvement, natural fertilizers, and bio-stimulants, accounting for a coherent Nature-Based-Solution (NBS) which allows trees to get rooted naturally, display health long-term growth and restore biomass, vivid ecosystems and fertile conditions for local food-production, in dry lands currently plagued by erosion and in a vicious circle where they lose the prospective of supporting any productive activities for the foreseeable future.

As for the results to-date, 6 months after the initial plantations, the documented survival rate of trees planted are above 90 percent, based on just 40 liters of water allocated to each sapling, and on average just one add-on injection, or 20 more litres of water, for each sapling.

Thus far, 770 trees have been planted in Dhofar as part of the initial phase of the project agenda. The planting started with 10 trees as control units in the nursery of MECA in Qairoon Hereti in February and were followed by plantation on several occasions on MECA’s designated site 16 km north of Mirbat, where an additional 730 trees had been planted as of May 2019, before the commencement of the Khareef. The average height of the trees has, since the time of planting until end-August, increased from a few decimeters to a height of 60 cm – 1,3 meters.

B. Species Planted

The prioritized species are all native to the Dhofar region, include: Boswellia Sacra, Ziziphus Spina Christi, Acacia Tortilis, Acacia Senegalensis, Acacia Geraldii, Acacia nilotica and Tamarindus indica.

C. Zones of relevance to tree planing in Dhofar

Two main ecological zones have been identified as priorities for Waterboxx usage in Dhofar.  These are (as also numbered in the Figure xx below):

4 - the Dry Plateau, where monsoon moisture levels decrease with distance from the wet escarpment; and

5 - the North-facing Cliffs and wadis, which receive little surface moisture during the monsoon.

NB Plant species, as stated already, must crucially be differentiated according to their preferred ecological zones.
