This area has been strongly influenced by the heavily populated Eskişehir settlement which is significant both from the viewpoints of agri¬cultural activity and industrial complexes. In coming years, economic significance of the Eskişehir area is anticipated to increase as the share of agriculture and industrial investments rise in the country. The sensitivity to erosion by water of extensive agricultural areas and the expected strong droughts as well as the heavy urbanization and the dependence of agriculture on increasingly polluted surface and groundwater irrigation in places necessitate an integrated approach that overlaps with the purpose of the DESIRE initiative, in order to provide a sustainable development in the region.

Added value of DESIRE for stakeholders
Added value of DESIRE for stakeholders in the SS is the participatory approach. There is a low level of contact between stakeholders. Organization is poor and the workshops are a help to connect farmers with farmers and farmers with researchers. In the beginning of the workshop people did not see an added value of DESIRE.

There is a gender problem; women do not join workshops. One should work through village elders. People traditionally gather and discuss in coffee houses and tea houses. Could this be used to discuss degradation and land use?

Study site stakeholders workshops
3-day stakeholder workshops were organized. On the 3rd day the GO’s and NGOs were invited to participate. Half of them left during the day. Farmers are reached by the government through workshops that are advertised in local media such as TV and radio. Farmers complain that the market prices are too high, while the price at which products are bought by middlemen is low.

Limitations for spontaneous implementation of soil and water conservation practices
A limitation to the spontaneous adaption of new methods are investment costs and low level of contact between stakeholders limiting exchange.

Stakeholder groups

• Provincial Division of the State Water Affairs: The local branch of the primary executive state agency for elimination of adverse effects of Turkey’s surface and groundwater and putting them in public utilization in various ways such as hydropower, irrigation, domestic and industrial use. This institution is passively involved in DESIRE since it previously constructed the Keskin Dam in the study site area.
• Anatolian Agricultural Research Center: A governmental organization conducting various research activities including production of drought resistant new species, amelioration of meadows etc.
• Provincial Special Management: The older General Directorate of Rural Services, now bound directly to local governor. It is expected normally to distribute infrastructure services such as road and aqueduct building or repair, etc.
• Provincial Directorate for the Environment and Forestry: Local state branch responsible for reforestation and environmental rehabilitation and protection.
• Soil and Water Research Institute, Eskisehir Branch: Branch of an organization (The Ministry of Agriculture and Rural Service) aiming at the development, conservation or suitable exploitation of the soil and water resources in the Eskisehir region. This institute previously made some research projects in relation to various aspects of land degradation in Eskisehir regions.
• Eskisehir Osmangazi University, Faculty of Agriculture: As a state university, this organization realises both education (undergraduate and MSc) and researches on productivity and land degradation issues.
• TEMA Eskisehir Branch: A branch of Turkish NGO for combating soil erosion, for restoration and protection of natural habitats.
• Foundation For The Reinforcement of the General Directorate of National Parks and Game-Wild Life : A Turkish NGO focused on the protection of environment with its wild life.
• UNCCD National Focal point: The national connection point against desertification founded under the Research, planning and co-ordination board of the Ministry of Environment and Forestry.
• Tepebasi Municipality: Decision-maker and execution authority within the municipality boundary with respect to land management and related issues. Since the majority of the study site included within the municipality with the latest local legislative rearrangements, this organization has ultimate significance.
• Local Irrigation Unions: The union of villagers (end-users) for provision of surface and ground waters to their farms.
• Local Farmer Unions: The union of villagers for increasing the productivity of soil and and crop quality.
• Eskisehir Agricultural Credit Cooperation: An NGO that provides various agricultural credits to farmers.   

Sustainability goals

The mountain villages (i.e. Uludere and Egriöz villages) of the study site still have significant number of cattle that frequents the pasturelands. For those stakeholders, increasing biological diversity as well as the amount of fodder production in pasturelands is the basic sustainability goal.

Dry croplands which are generally slightly to highly sloping actually undergo significant water erosion though neither farmer nor state organizations are financially capable of taking protective or mitigation measures. But they rather think of preserving or improvement of soil fertility as the major sustainability goal. For this reason they mostly prefer chemical fertilizers instead of mid-to long term soil preservation measures. Enlargement of forest cover and their maintenance and protection are viewed as fundamental sustainability goals by both farmers and state organizations.  Lastly, optimum use of groundwater by any means in the irrigated croplands of the Keskin and Yukarisögütönü villages are adopted as principal sustainability goal by farmers of these villages.

The table shows the sustainability goals that were identified for the Eskişehir area.

»Stakeholders & their sustainability goals - overview

To help understand this complex picture it can be helpful to think in terms the dominant socio-economic and environmental forces that are driving the process of land degradation. These place pressures on the land which have particular impacts. Human society may have already made responses to those impacts, or may have knowledge about how they could respond. Decisions about which responses to make may also be governed by a range of international, national or local policy regulations and agreements.

In the Eskişehir study site, the same stakeholder workshop and questionnaires that were used to identify existing and potential response strategies (»Identifying strategies: Stakeholder workshop 1) also discussed and identified these driving forces; pressures; impacts; and the policy and regulation environment. This information was then used to inform the choice of »Field experiments, the scenarios used in »Simulated biophysical impact of remediation strategies and their financial viability, and context for the study site-specific »Policy brief recommendations.

Comments

Map version: 4Oct11

In the Eskişehir study site, the main processes or causes of desertification were water erosion in forests, water erosion in agricultural areas and water erosion in pastures & shrubs.   For these processes, the Desertification Risk Assessment Tool processed 207 indicators in 13 map units. The indicator values were obtained from the WOCAT database and used as input to the Assessment Tool. The procedure was applied for all the map units of the Eskişehir study site and the DRI values calculated are shown in Table 1.

Table 1. Description of desertification risk

The DRI values were mapped for each of the 13 polygons (Map 1).

Map 1: Desertification risk index (DRI)	Map 2: Degree of land degradation (as assessed using the WOCAT mapping method)

The DRI map was compared with WOCAT QM of the study site (Map 2). It was noted that the degree of degradation and the effectiveness of the conservation measures on the WOCAT map corresponded closely enough to the DRI values for the same areas. The highest degree of degradation and the lowest effectiveness of the conservation measures matchedthe highest values of DRI.

Introduction
The hill slope areas near Eskişehir suffer from soil erosion. The area is semi-arid, soils are shallow, stony and organic matter content is low. Land use is rainfed wheat with occasional fallow periods. Slopes range from 10 to 20%.  Late spring and early summer rainfalls are particularly erosive (400 mm annual rainfall with a marked dry season). Experiments were carried out that interrupt the runoff and help increase infiltration and thereby increasing soil moisture storage (wicker fences as sediment traps and contour ploughing). The overall objective is to decrease surface runoff and to reduce soil losses. Land abandonment in the area occurs because of urban migration.

Desertification indices
Desertification expresses itself as water erosion and possibly tillage erosion. Both get a rating of moderate with a rating of 2.82 and 2.91 respectively. The measures are difficult to implement. The wicker fences will cause terraces to be formed gradually. Implementing terraces only decreased the water erosion risk only slightly to 2.64.

Implementing a maximum interruption of runoff as a result of contour ploughing decreases water erosion risk to 2.66.

Implementing both terraces and contour ploughing decreases the erosion risk to low: 2.48.

Wheat production on slopes without conservation measures

Conclusions
The general moderate water erosion risk is correct for the area where erosion is present but not excessive. The precise experimental measures (contour ploughing and wicker fences) could not be implemented but when translated to interruption of runoff and terracing give a small result. In reality the result was observed ones where the treated field had no erosion while the adjacent fuield did have erosion. Decreased runoff also expressed itself as a higher infiltration and increased water availability. This link is not made in the assessment tool (as it is built on correlation, not on process relations).

»Identifying strategies: Stakeholder Workshop 1 methodology and summary results from all study sites

Stakeholder Workshop 1 identified a number of existing or potential strategies to combat desertification and land degradation in the Eskişehir study site. In the months following the workshop these strategies (technologies or approaches) were documented and evaluated in a structured and standardised way and their descriptions were entered in the WOCAT Technologies and Approaches databases in order to share the information with other DESIRE sites as well as globally.
