RSM-03 Detection of charcoal production sites in southern somalia using very high resolution imagery

Following more than 20 years of civil unrest, environmental information for Southern Somalia is scarce while there is clear evidence that the war economy fuelled by the conflict is rapidly depleting the country’s natural resources, especially the woody biomass. Wood charcoal production is one of the most relevant businesses supporting war regimes such as the extreme Islamist group Al Shabaab, which has ruled in Southern Somalia from 2006 to 2012 and is still occupying large areas. In this study, we first used Very High Resolution (VHR) satellite imagery of early 2011 and early 2013 for developing a semi-automatic mapping method of charcoal production sites as a proxy of tree loss over a 6000 km2 area along the Juba River in Southern Somalia. The user’s accuracy of semi-automatic charcoal production site detection varied between 81.7% for 2011 and 87.3% for 2013, while the producer’s accuracy was 68.2% and 65.5% respectively and, as compared to visual interpretation, reduced significantly the required time. The analysis of the changes between the two dates led to an average tree loss estimation of 3.3%, corresponding to 520,520 trees over the 2 years period. The results help to better understand the dimension and impact of charcoal production in Southern Somalia and are a first step towards the development of a charcoal production monitoring system.

Mapping Forest Degradation Caused by the Recent Increase of Charcoal Production in Southern Somalia

Following more than 20 years of civil unrest, environmental information for Southern Somalia is scarce while there is clear evidence that the war economy fueled by the conflict is rapidly depleting the country’s natural resources and especially the woody biomass. Wood charcoal production is one of the most relevant businesses supporting war regimes such as the extreme Islamist group Al Shabaab, which has ruled in Southern Somalia from 2006 to 2012 and is still occupying large areas. In this study we first used Very High Resolution (VHR) satellite imagery of February 2013 for developing a semi-automatic mapping method of charcoal production sites as a proxy of tree loss over a 754 km2 woody area along the Juba river in Southern Somalia. The accuracy of semiautomatic charcoal production site detection varied between 80 and 95% as compared to visual interpretation and reduced significantly the subjectivity and the required time. The analysis was then applied to previous years (2011-2012) for a 52.6 km2 subset of the study area, and led to a tree loss estimation of 8.63%, corresponding to 15,434 trees over the 3 years period. The results are crucial for better understanding the dimension and impact of charcoal production in Southern Somalia and are a first step towards the development of a charcoal production monitoring system.

Mapping Charcoal Driven Forest Degradation during the Main Period of Al-Shabaab Control in Southern Somalia

Following more than 20 years of civil unrest, environmental information for Southern Somalia is scarce while there is clear evidence that the war economy fueled by the conflict is rapidly depleting the country's natural resources and especially the woody biomass. Wood charcoal production is one of the most relevant businesses supporting war regimes such as the extreme Islamist group Al-Shabaab, which has ruled in Southern Somalia from 2006 to 2012 and is still occupying large areas. In this study, we map and quantify the tree loss suffered by the region due to the rapid increase in illegal charcoal production and export over recent years. Very high-resolution (VHR) satellite imagery is used to visually count charcoal production sites as a proxy of tree loss in two sample areas within the lower Juba region of Southern Somalia. The image interpretation allows mapping the charcoal production sites as well as estimating tree loss rates above 7% over 5 years. The results are crucial for understanding the exact dimension and effects of the loss of woody biomass and for planning conservation and recovery interventions in the concerned area.

W-22 Water Demand Assessment for the Juba and Shabelle Rivers

The Juba and Shabelle rivers are the only perennial streams in Somalia. They originate in Ethiopia, where over 90 percent of the stream flow is generated. The two river basins cover an area 174,600 km2 within Somalia. Basic monitoring of the two rivers and their basins has been ongoing in the previous SWALIM projects, laying a good foundation for more developed, continuous river monitoring and data processing (automatic weather stations, continuous discharge measurements, sediment and water quality monitoring together with pilot land degradation monitoring systems). The Juba and Shabelle basins are also called the ‘breadbasket’ of Somalia: It is the centre of agricultural and livestock production and home to the majority of the Somali population.

Somalia Water and Land Information Management, Nairobi (Kenya)

W-21 Climate CHange Impacts on Water Resources of Somaliland and Puntland

Identifying, assessing and developing groundwater resources is now an urgent priority for emergency relief and long-term development in all countries in the Horn of Africa affected by drought and water scarcity. As a response to this context, UNESCO, in May 2012, launched the initiative “Strengthening Capacity to Combat Drought and Famine in the Horn of Africa: Tapping Groundwater Resources for Emergency Water Supply” through support of the Government of Japan. The overall project aims to map-out drought-resilient groundwater resources in affected areas and strengthen regional capacities in managing groundwater for drought-preparedness. In order to take advantage of the established network and experienced profile of UNESCO’s partner FAO-SWALIM (Somalia Water and Land Information Management) in Somalia, an agreement of this UNESCO-FAO partnership was formalized that governs the framework of the overall project. As part of this project, SWALIM has recently finalized a hydrogeological survey and assessment in selected areas of Somaliland and Puntland which has come up with a wealth of information on potential groundwater resources which supplements SWALIMS previous activities in Somali water and land resources information management.

RSM-02 Estimating Cultivable Areas in Central and Southern Somalia using Remote Sensing

Somalia is largely a hot, arid and semi-arid country with rainfall amounts averaging between 50 and 500 - 600 mm per annum (even though some areas may receive slightly higher amounts).To provide a first estimate of the cultivable land, this study analyzed ASTER satellite images (and where not available, other medium resolution images) for 2010 and 2011 to generate information about cultivation in central and southern Somalia. The results of this study will be the basis for a successive, more accurate analysis which will include sampling approaches and field validation (through FAO emergency staff and FSNAU monitors) in order to establish the potential cultivable land and estimate production for the different cropping systems at farmer and district levels.

Assessment of Charcoal Driven Deforestation Rates in a Fragile Rangeland Environment in North Eastern Somalia Using Very High Resolution Imagery

Multi-temporal very high-resolution satellite images and field work have been used for quantifying the tree cutting rate over a 5 years period in a very arid tiger bush area of North Eastern Somalia with intensive charcoal production activities. By applying both a classical area frame sampling approach with visual interpretation of the samples and a semi-automatic tree detection algorithm, it was possible to create baseline tree density layers for the 2 years of observation and to quantify the tree cutting rates for the period from 2001 to 2006. An average annual tree loss of −2.8%, coupled with the total absence of regrowth during the 5 years study period, confirm the tremendous ecological impacts of charcoal driven tree cutting on tiger bush vegetation. Analysis of the results evidences spatial and temporal patterns in the cutting locations and poses the basis for a better understanding of the ecological and human dimensions of deforestation in the fragile rangeland environment of Northern Somalia.

A Framework for National Assessment of Land Degradation in the Drylands: A Case Study of Somalia

Land degradation is a gradual, negative environmental process that is accelerated by human activities. Its gradual nature allows degradation to proceed unnoticed, thus reducing the likelihood of appropriate and timely control action. Presently, there are few practical frameworks to help countries design national strategies and policies for its control. The study presented here developed a framework for the national assessment of land degradation. This framework is envisaged to support governments in formulating policies on land degradation. It uses time-series remote sensing data to identify the rate and extent of land degradation, local experts to identify prevalent degradation types and drivers of the degradation and field observations to validate the overall assessment. Its simplicity, use of freely downloadable input data and self-triangulation of the assessment methods make it suitable for rapid assessment of land degradation on a national scale. It was tested in Somalia, where it exhibited accuracy greater than 60 per cent when assessing land degradation. This framework is relevant for designing national strategies and policies that address land degradation and provides an opportunity for accurate identification of areas to target with comprehensive local assessment. Testing of the framework in Somalia showed that about one-third of the country was degraded because of loss of vegetation cover, topsoil loss and to the decline of soil moisture. Overgrazing, excessive tree cutting and poor agronomic practices in agricultural areas were identified as the primary drivers of the country’s land degradation. These drivers are encouraged by the prevailing communal land tenure practices, poor governance and civil war. Copyright © 2011 John Wiley & Sons, Ltd.

An Assessment of the Surface Water Resources of the Juba-Shabelle Basin in Southern Somalia

The water resources of the Juba and Shabelle rivers in southern Somalia are important for irrigation and food production, but are influenced by seasonal floods. Prior to the outbreak of civil war in 1991, the Somali Ministry of Agriculture successfully operated a hydrometric network covering the Juba and the Shabelle, data from which provided input to a flow forecasting model. The war resulted in the neglect and abandonment of monitoring stations and an enforced cessation of data collection and management. In 2001 and 2002, part of the pre-war hydrometric network was reinstated and water levels were again recorded at some stations. This paper examines the implications of the 11-year hiatus in data collection, and the now much reduced monitoring network, for assessing and managing the surface water resources. The problems faced have relevance to other basins, within Africa and elsewhere, where there has been a similar decline in data collection.
