Changes in farm management and agricultural activities and their effect on farmers' satisfaction from land consolidation: The case of Bursa-Karacabey, Turkey
(Routledge Journals, 2009) Yaslıoğlu, Erkan; Aslan, Şerife Tülin Akkaya; Kirmikil, Müge; Gündoğdu, Kemal; Arıcı, İsmet; Uludağ Üniversitesi/Ziraat Fakültesi/Tarımsal Yapılar ve Sulama Bölümü.; 0000-0001-5129-8642; 0000-0001-5129-8642; 0000-0002-3865-7863; AAH-2955-2021; AAL-5730-2020; ABE-6643-2020; ABI-4047-2020; N-9721-2013; 20437021400; 16229430800; 20436307800; 12784402000; 12784126000
In Turkey, the scattered, fragmented plots in agricultural areas are one of the major problems preventing agricultural efficiency. Land consolidation is an effective tool in improving efficiency, but the success depends greatly on farmers' satisfaction and adoption. Therefore, determination of issues important to farmers can positively influence future land consolidation projects. As such, land consolidation studies must be accelerated and extended nationwide in countries where land fragmentation is common and rural development is essential. This study determined the effects of changes in farm structures and agricultural activities on satisfaction with land consolidation. Nine villages in the Bursa-Karacabey (Turkey) plain irrigation area were selected as study sites, and the logit model was used to analyse survey data including 190 respondents. Our results indicate that farmers' age (AGE), easiness in crop pattern planning (CRPT), reduction in distance between farmstead centre and plots (DFCP), reduction in time consumed in accessing the plots (TIMES) and improvement in working conditions in the fields (WORC) significantly affected the satisfaction with land consolidation. All of these factors except farmers' age (AGE) are related to consolidation of scattered, fragmented and tiny parcels into larger plots with suitable shape and size for agriculture. Consolidation also increased production and further improved working conditions.
Effects of irrigation system management turnover on water table depth and salinity of groundwater
(Triveni Enterprises, 2007-04) Gündoğdu, Kemal Sulhi; Aslan, S. Tulin Akkaya; Uludağ Üniversitesi/Ziraat Fakültesi/Tarımsal Yapılar ve Sulama Bölümü.; 0000-0001-5129-8642; AAL-5730-2020; ABI-4047-2020; 12784402000; 57222306888
In recent years, management of large, state owned irrigation projects in Turkey have been transferred to water users such as farmers cooperatives or associations in order to reduce the financial burden on the government and to increase irrigation efficiency and farmer participation. Water table depth and groundwater salinity are important factors in irrigation systems, not only for plant growth but for human health as well. The objective of this study was to determine the impact on water table depth and groundwater salinity for transferring management of the Mustafakemalpasa irrigation project (19, 370 ha) in north-western Turkey to local, farmer controlled irrigation districts. Maps of water table depth and groundwater salinity were created for the a month of July (averaged over several years), the month with the highest amount of applied irrigation water, based on measurements made in 200 wells in the project area before and after transfer of managerial control. Both depth of the water table and salinity decreased after transfer The area with average water table depth of 100-200 cm was 25.41% of total area before turnover and 79.45% after and the area with water table depth 200-300 cm was 73.4% before turnover and 20.50% after before turnover, the area with average groundwater salinity 1.5-2.0 dS/m was 26.16% of total area, and that with average salinity 2.0-2.5 dS/m was 61.73% of total area; after turnover, average groundwater salinity was 1.5-2.0 dS/m in over all areas. Both changes were the consequence of an increased amount of applied water after transfer of the control of irrigation management from the state to local irrigatior districts controlled by farmers. In the short run, the farmers will get benefit from increased irrigation. However, over the long term, if water table depth continues to decrease then secondary salinization could become a major hindrance to irrigation sustainability.
Environmental protection-based village development: The case of Eskikaraagac
(Parlar Scientific Publications (P S P), 2007) Yaşlıoğlu, Erkan; Aslan, S. Tulin Akkaya; Kirmikil, Müge; Arıcı, C. Franziska; Gündoğdu, Kemal Sulhi; Arıcı, İsmet; Uludağ Üniversitesi/Ziraat Fakültesi/Tarımsal Yapılar ve Sulama Bölümü.; 0000-0001-5129-8642; 0000-0002-3865-7863; ABE-6643-2020; N-9721-2013; AAH-2955-2021; 20437021400; 57222306888; 20436307800; 12784402000; 12784126000; 20435271500
The goal of this study was to investigate the effects of the Stork-Friendly Villages Project and other environmental protection projects in Bursa-Karacabey-Eskikaraagac on village development and the local people. In general, the respondents regarded these projects favorably. The projects positively influenced attitudes toward environmental conservation, and the higher the educational level the greater the reception to conservation (p < 0.01). Respondents who thought that these projects positively affected tourism potential were likely to be males (p < 0.01). Education was significant (p < 0.01) in explaining the relationship between demographic variables and peasant consciousness (respondents who believed that the project positively affected peasant consciousness were likely to be educated at the primary grade level or to be illiterate). The positive attitudes of the respondents affirmed that the success of such projects depends on certain issues. However, local people should be supported and encouraged to pursue tourism, agriculture, and local economic activities to achieve their goals. People in the villages should be supported with financial instruments, such as low interest rates and long-term pay back loans.
The hidden fragmentation after land consolidation in Turkey
(Parlar Scientific Puplications, 2017-07-24) Kırmıkıl, Müge; Aslan, Şerife Tülin Akkaya; Gündoğdu, Kemal; Arıcı, İsmet; Uludağ Üniversitesi/Mühendislik Fakültesi/Biyosistem Mühendisliği Bölümü.; 0000-0001-5129-8642; AAH-2955-2021; AAL-5730-2020; N-9721-2013; ABI-4047-2020
It is accepted that inheritance is the primary cause of land fragmentation. The inheritance law is the leading significant cause of fragmentation or shrinking of land. Inheritance laws applied in most countries facilitate or demand the subdivision of holdings into equal parts among all heirs or in some countries among only sons. Intense fragmentation or shrinking of agricultural land is a significant problem in Turkey. Inheritance law in Turkey prescribes equal distribution of agricultural land which is subject to heritage. When there are disputes towards the inheritance distribution, the new owner's submission of deed is not done. This situation brings out the truth that an agricultural land which seems as one piece is used by more than one person in reality. In this study, it is aimed to evaluate public and hidden joint ownership in the areas where land consolidation is done. As study field, the data related to Bursa-Karacabey Plain villages were used where the most intensive agricultural activities are done in Turkey. In the study area, in order to determine joint ownership which is off the record Ismetpasa, Beylik and Yenisaribey villages are chosen and survey study was applied. After land consolidation in this study area, heirs wanted to own agricultural lands even if the plots are small and joint because the lands gained value, production became easier and yields increased, and alternative production opportunities arose. As a result, it was concluded that, after land consolidation hidden joint ownership is still going on in parcels, real joint ownership condition is mostly not recorded to registry of deeds.
Mapping multi-year ground water salinity patterns in irrigation areas using time-series analysis of ground water salinity maps
(Hydrological Processes, 2008-03-15) Gündoğdu, Kemal Sulhi; Aslan, Tulin Akkaya; Uludağ Üniversitesi/Ziraat Fakültesi/Tarımsal Yapılar ve Sulama Bölümü.; 0000-0001-5129-8642; 0000-0001-5129-8642; N-9721-2013; ABI-4047-2020; AAL-5730-2020; 12784402000; 57222306888
In irrigation areas, ground water salinity (GWS) levels may vary depending on the amount and quality of irrigation water applied and on the activity of the drainage system. GWS plays a vital role in irrigation systems by influencing whether the environment is suitable for plant growth. Hence, it is necessary to monitor changes in GWS both temporally and spatially. Maps are generally used to visualize this information. However, evaluation of temporal and spatial variations of GWS can be difficult because of the necessity of assessing many maps together to understand both temporal and spatial changes. In this study, a data assessment method that can be used for multi-year ground water salinity evaluations is presented. The method looks at the spatial and temporal relationships between the main salinity classes present in the study area, their typical locations (i.e. areas where the salinity classes are most frequently located), and the alternate salinity classes in those locations in any of the years of the time series. As a case study, the method was applied to multi-year (1990-2000) GWS observations in the Mustafakemalpasa irrigation project (19370 ha) in the Marmara region of north-western Turkey.
A multi-criteria model for land valuation in the land consolidation
(Elsevier, 2020-06) Tezcan, Ahmet; Büyüktaş, Kenan; Aslan, Şerife T. A.; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Biyosistem Mühendisliği.; 0000-0001-5129-8642; AAL-5730-2020; 16229430800
Land consolidation is an effective technique in land management that contributes to sustainable rural development. Land valuation is one of the most important steps in land consolidation because it plays an important role in the reallocation process. Land valuation is also an important problem in Turkey as in many countries in the world. Because the lands will be reallocated at the end of the consolidation process, it is very important to determine the precise value of each parcel. However, the methods used in land valuation in many countries lag behind current techniques and technologies. For this reason, a new method for land valuation is needed. The purpose of this study was to develop a new model based on multi-criteria calculations that is suitable for today's technologies and addresses the weakness in the current land valuation methods. In a case study of Solak, Antalya, Turkey, we identified fourteen key land value factors. Those factors were assigned weights by the Land Valuation Committee, academic staff, engineers, and local landowners. The weights were then integrated into a framework called the Land Quality Index. The land quality index factors are the criteria for evaluating the geographical, physical, and socio-economic structure of the region. The scores for each factor on each parcel were determined using GIS software. The total score of fourteen factors was then converted to a 100-point scale, that comprised the Land Quality Index. The land value of each parcel was determined by adding the soil index to the Land Quality Index. In our study, we also created three different models to investigate how the parameters were apportioned during the land valuation. We found that, while the current method used by the government agency (General Directorate of State Hydraulic Works) classified the lands into five groups, our methods classified the lands into 17, 20, 24 groups, respectively. In addition, while the deduction rate was 4.97 % in the current method, they were 4.89 %, 4.86 % and 4.85 % in our new models, respectively. The method we proposed in this study determined land values more accurately, precisely, and fairly compared to current method used by General Directorate of State Hydraulic Works. It is suggested that our models could be used instead of the current method in the land consolidation works in Turkey.
Personal, physical and socioeconomic factors affecting farmers' adoption of land consolidation
(Spanish National Institute of Agricultural & Food Research & Technology, 2007-06) Aslan, Şerife Tülin Akkaya; Gündoğdu, Kemal S.; Yaslıoğlu, Erkan; Kirmikil, Müge; Arıcı, İsmet; Uludağ Üniversitesi/Ziraat Fakültesi/Tarımsal Yapılar ve Sulama Bölümü.; 0000-0001-5129-8642; 0000-0001-5129-8642; AAH-2955-2021; AAL-5730-2020; N-9721-2013; ABI-4047-2020; ABE-6643-2020; 16229430800; 12784402000; 20437021400; 20436307800; 12784126000
Ownership of agricultural land is very fragmented in Turkey, as is the case in countries within central Europe. This prevents agricultural efficiency from reaching desired levels. Land consolidation involves redistributing land ownership so that individual farmers own fewer, larger, more compact and more contiguous land parcels. In Turkey, generally voluntary land consolidation projects are performed, while some financial limitations and political conditions prevent land consolidation reach to its desired level. For this reason, only 2.2% of the agricultural areas have been consolidated so far. Ideally, farmers adopt consolidation and are pleased by its results; this helps maintain the sustainability of the land structure formed by consolidation and accelerate acceptance of consolidation in other areas. In this study, the factors that are effective on farmers' adopting land consolidation and their contentment were investigated. For this purpose, the results of the survey carried out in the selected villages within the Bursa-Karacabey plain were assessed using a logit model. According to the results obtained from this consolidation study, the criteria farmers value are the utilization of the irrigation system, reduction of inter-farmer conflicts, shaping parcels into a form proper for mechanized agriculture, and forming parcels of large dimensions by consolidating parcels. A higher level of contentment was observed among the farmers who were provided with above mentioned factors.
Reallocation model for land consolidation based on landowners’ requests
(Elsevier, 2018-01) Arıcı, İsmet; Akkaya Aslan, Şerife Tülin; Kirmikil, Müge; Gündoğdu, Kemal Sulhi; Uludağ Üniversitesi/Ziraat Fakültesi/Biyosistem Mühendisliği Bölümü.; 0000-0001-5129-8642; AAL-5730-2020; AAH-2955-2021; ABI-4047-2020; 16229430800; 20436307800; 12784402000
In a land consolidation project, preparation of the reallocation plan is a crucial and challenging stage with many factors playing a role. It is quite difficult to identify these factors and their contributions. The most important element in the allocation stage is the opinions of the landowners regarding the new location of their parcels. Projects are more successful when landowners' opinions are evaluated and considered. Current technological developments may facilitate the inclusion of the landowners' requests in the project. The land consolidation and reallocation phase is time-consuming and complex and forms the basis of the project. The biggest problem at that stage is block balancing. Therefore, in this study, we evaluated the performance of a reallocation model to perform block distribution by evaluating landowners' requests. The model was tested in four villages (Baharlar, Calikoy, Hirka, and Sofular) of the Denizli province, Tavas district (Turkey) where land consolidation work had been done before. Using the model, the excess distribution rates in the blocks were reduced to between 0.03% and 2.09%. In addition, the fulfillment ratio of first requests was 80-90% using the model; while, it was only 66-83% when the work was done without the model. The most powerful part of the model is to process the data within minutes compared with weeks or months for the project engineer. Thus, the model should save time and improve results for future land consolidation projects.
