Homegardens in Landscape Architecture – A Case Study of Hazelnut Plantations

Landscape can be defined as from one point of view enter into the framework of a view that they produce a combination of natural and cultural assets (Council of Europe, 2000). At the same time, objects or land covers around us and how we perceive and how the relationship between nature and culture has the meaning established. Landscapes are the most important elements in building spatial identities. Landscapes, sometimes with their natural and cultural features can provide information about the way of life of the people. They are used in a sustainable manner for future generations and makes sense economically. The decisions to get to taken whether rural or urban landscape in the continuity, management and use of the quality of life of people are very important.


Introduction
Landscape can be defined as from one point of view enter into the framework of a view that they produce a combination of natural and cultural assets (Council of Europe, 2000).At the same time, objects or land covers around us and how we perceive and how the relationship between nature and culture has the meaning established.Landscapes are the most important elements in building spatial identities.Landscapes, sometimes with their natural and cultural features can provide information about the way of life of the people.They are used in a sustainable manner for future generations and makes sense economically.The decisions to get to taken whether rural or urban landscape in the continuity, management and use of the quality of life of people are very important.
Landscapes are divided into three basic groups as natural, semi-natural and cultural (artificial) (Atik, 2009).Natural landscapes include areas that there is little or no human impact such as mountain forest, river, and lakes (Çepel, 1988).Semi-natural landscapes are dominated by the majority of the natural areas of land cover change in the form of areas that are too small.Urban, recreational, agricultural and industrial areas formed cultural or artificial landscapes.
Agricultural landscapes that are one of the four elements of cultural landscape (Karahan and Orhan, 2008) are the main land use form and the resulting high visibility leads to a widespread perception of rural farming.The importance of preserving agricultural landscapes is determined as (EC, 2012);


traditional agricultural landscapes form part of the cultural and natural heritage,  the ecological integrity and the scenic value of landscapes make rural areas attractive for the establishment of enterprises, for places to live, for tourism, and recreation businesses Agricultural landscapes include fruit and vegetable gardens, livestock and flower-growing businesses, watering plants.In addition, these areas have been adapted human life as field which is a recreational, a peaceful space, spending leisure time (Gökalp and Yazgan, 2013).
Agricultural landscapes are an important field in Turkey.Agricultural activities show ranging from one-year to multi-year products (Table 1).Hazelnut plantations are in fruit orchards and other permanent crops.Hazelnut plantations cover 7 138 320 da in agricultural landscapes in Turkey (Table 2).Hazelnut plantations are located in northern, eastern and middle Black Sea Region of Turkey (Turna, 2012).In recent years, a new concept that emerged in the agricultural landscape has been the homegardens.

Homegardens in Landscape Architecture -A Case Study of Hazelnut Plantations 763 What is "Homegarden"?
Homegarden is an agroforestry term for any agro-silvo pastoral activities carried out intentionally within one's houselot primarily for food, but also for medicine, side-income and landscape (Mohan, 2004).
Homegardens are unique agroforestry systems.These intensive land-use systems involving the planned management of multipurpose trees and shrubs grown in intimate association with herbaceous species (mainly annual, perennial, and seasonal agricultural crops), and livestock, are all managed within the compounds of individual homes (Fernandes andNair, 1986 andMohan, 2004).Homegardens provide both economic and social advantages.They, with their various agricultural crops and trees, accomplish the basic needs of the local population.In addition, homegardens provide economic benefits while remaining ecologically sound and biologically sustainable (Mohan, 2004).
There are the relationship between homegardens and landscape architecture as ecological and visual.


As ecological, socioeconomic structure, cultural behaviors and personal preferences, seem to be the main characteristics of the appearance, function, and structure of homegardens (Christanty, 1990, Mazumdar andMazumdar, 2012).The homegardens usually have more various plant canopy types and thus they are more complex than the urban or rural gardens.The crops, ornamental plants and trees planted in a homegarden are carefully arranged to provide for specific functions and benefits, which are primarily economic in nature.The other effects of ecological relation of homegardens to landscape architecture are their complexity of patterns, diversity of plants, naturalness or not and climatic features.


As visual, generally, the places are where people live and threw the day unwinding.They are focal points combining people with have a range of plant richness and diversity.Most of the time, the people who live in these places is highly valued as a visual riches on offer.Therefore, the characteristic features of each garden include cultural designs (Moreno-Black et al., 1996 andMohan, 2004).

An application on homegardens in hazelnut plantations
Homegardening is a traditional agroforestry system where a clearly bounded piece of land immediately surrounding the dwelling house is cultivated with a mixture of perennials and annuals.Can homegardens conserve biodiversity and develop landscape planning in Turkey?This is an important question, given the low forest cover in the country and peoples' high dependency on the natural production systems.The first step in assessing the conservation value of homegardens is to undertake a thorough botanical and structural survey.Total plant diversity measures the direct conservation value of homegardens, while structural features may indirectly conserve other taxa, such as birds, reptiles, amphibians, small mammals, or arthropods (Kabir and Webb 2007, Sunwar et al. 2006, Smith et al. 2006, Peyre et al. 2006, Ali 2005, Blanckaert et al. 2004, Wezel and Bender 2003).Homegardens are an integral part of the farming system, an adjunct to the house where selected trees, shrubs and herbs are grown for edible products and cash income (Pandey et al. 2007, Trinh et al. 2003, Ceccolini 2002).
Homegardens are a common feature in Turkey like what they are in many countries, and often exhibit remarkable variability in composition and structure in geographic regions of Turkey.The homegardens in urban in the Black Sea region in Turkey related to urban-rural are basically the determiners to form the urban and regional landscape patterns.In this region, the homegardens having minimal and limited area, the importance and functions with effective systems contains mainly the hazelnut (Corylus avellena) and tea (Camelia chinensis) plantations.The hazelnut plantations are more common than the other agricultural crops in Northern Black Sea Region of Turkey especially in Trabzon.

Study Area
This stage has been carried out within the city of Trabzon, in the northeastern Black Sea Region of Turkey (401330N-411070N; 371070E-401300E UTM) (Figure 1-2).The city of Trabzon, which covers an area of approximately 4.685 km2, has a population about 283.233 inhabitants making it the third largest principal city in the region (Anonymous 2008).
The aim of this study is to determine the potential of contributions of landscape planning and designing of the homegardens in Trabzon city of Turkey.Therefore, the hazelnut plantations were evaluated in Trabzon city.3).

Results
Turkey has 9 cultivated Corylus avellana taxa and they are named differently by the indigenous people (Anonymous 2007).
The species near the borders, in deeper sides and under the hazelnut plants in the research areas were identified.According to this research, totally 90 annual and biannual species (19 species near the borders, 14 inside and 57 under the hazelnut plants) were identified (Figure 4) (Table 3).
Hazelnut is one of the most important income resources among all agricultural products in Turkey and the country is number one in the list of hazelnut producers with the rate of 72 percent all over the world.Trabzon and its neighborhoods have important hazelnut plantations and most of the green areas in the urban side are these hazelnut fields (Reis, 2003).
Hazelnut fields are on slopes of the riverbanks in general, especially because of the geography of the Black Sea Region.Indigenous people in the area plant some trees to conserve their hazelnut fields and to make the borders of neighborhoods clear (Table 3).

Conclusions
The results of this study can be given the following items.


Hazelnut plantations are very important income resources for the indigenous people.


The homegardens having hazelnut plantations are the most dominate open green areas in and around Trabzon city. Some agricultural products such as hazelnut, tea etc. creates habitats for some other plants, which makes a serious contribution to biodiversity in urban areas.


It is easy to claim that hazelnut fields are useful to get some fruits at the same time.That is the reason that hazelnut plantations should be supported for agroforestry studies. Homegardens contributes to floral diversity of landscape architecture with owned plant biodiversity.


Especially, agricultural landscapes have different visual preferences affect people as visual effects.In this context, their diversity of size, color, texture, form effect on and visual state of landscape. Agricultural landscapes are in the landscape ecology concepts as patch and matrix (Forman, 1983, Forman and Godron 1986, Forman, 1995).According to Eroğlu, 2012, plant compositions that created by agricultural patches are important landscape element both visually and ecologically.Therefore, homegardens are important ecological patches and landscape elements.


Homegardens and agricultural landscapes are to consider landscape components with their visual and ecological potentials in optimal land use planning, landscape development plans, development plans, landscape plans and local levels in terms of design applications.
Homegardens include some cultural features such as plant material, planting style, agricultural applications and architectural structure.In order to evaluated tothese characteristics in tourism and tourism planning, they must be investigated and explored.
