Gendered Homegardens: A Study in Three Mountain Areas of the Iberian Peninsula

Gendered Homegardens: A Study in Three Mountain Areas of the Iberian Peninsula. As an example of the importance of gender relations in the use of natural resources, several authors have analyzed the role of women in homegardens. Gendered differences in homegarden management have been difficult to disentangle due to the often–shared nature of gardening. Here, we use an innovative approach to analyze gendered differences in the characteristics and management of homegardens. Specifically, we use information on the prevalence of different household members in gardening activities to classify homegardens as women’s, men’s, or shared. Then, we compare several garden characteristics across the three types of homegardens. For the case study, we use data from homegardens in three rural areas of the Iberian Peninsula. We found that household members generally share homegarden responsibilities in these three regions and that many homegarden characteristics vary with the distribution of gardening tasks. Specifically, we discovered that gardens managed mainly by men were larger, more distant from the dwelling, and better exposed than gardens managed by women. Men and women also used different management techniques; organic fertilizers and traditional pest control management systems predominated in gardens managed by women. Men and women also differed in how they reportedly use garden products, with women favoring household consumption versus sale or gifting. Last, gardens managed mainly by women had a larger diversity of uses for species and a larger diversity of species per unit area. Cultural norms of what is considered appropriate behavior for men and women help explain differences in garden characteristics and their plant composition and structure.     

Karen Homegardens: Characteristics,Functions, and Species Diversity

Diversity is one of the most important traits of homegardens and contributes to maintaining their functions. Here, we investigated the diversity, characteristics, and functions of 75 Karen homegardens from four villages in Chiang Mai and Tak provinces in northern Thailand. In each homegarden, all used plant species were registered and classified according to their main use. The diversity and richness in each homegarden was estimated and the stratification of plants in horizontal zones was investigated. A total 268 plant species were recorded, ranging from 100 to 146 species in each of the four villages. These plants were mostly kept in the homegarden yard or along their boundaries. The most common species were mango (Mangifera indica L.), jackfruit (Artocarpus heterophyllus Lam.), guava (Psidium guajava L.), and taro Colocasia esculenta (L.) Schott. Besides these species, most plants differed from one village to another. Distance between the homegardens was important; homegardens in the same village were more similar than those in different villages. However, beyond the individual level, the distances alone could not be used to determine similarity. Despite the variation of species found in homegardens, the function and horizontal stratification of the Karen homegardens shared many traits. They satisfied both physical and aesthetic needs to the Karen people as witnessed by the high proportion of food and ornamental species. The reverse effects of urbanization (we used the distance from the nearest urban area as a proxy) on the diversity of ornamental species was also observed. In general, Karen homegardens had high richness and diversity which directly benefited the conservation of plant species. This diversity promotes food security at the household and community levels.     

Plant Diversity in Hmong and Mien Homegardens in Northern Thailand

Plant Diversity in Hmong and Mien Homegardens in Northern Thailand. We surveyed 180 homegardens in three Hmong and three Mien villages in northern Thailand to study their floristic diversity and composition and to understand the impact of forced migration and ecological conditions for the development of the rich homegarden flora. We also looked at the role of culturally important species as carriers of cultural identity. We found 406 species: 341 (99 families) and 270 species (90 families) in Hmong and Mien homegardens, respectively. Five lowland villages had the richest homegarden flora, in part due to the presence of many widespread species. Twenty-two species were widespread in tropical countries and found in most Hmong and Mien homegardens, and 14 additional common species were shared between Hmong and Mien homegardens. Seventeen species were exclusive to Hmong homegardens and eight to Mien homegardens; these we have designated as culturally important species. The presence of culturally important species determines the homegardens’ characteristics and reflects the cultural identity related to plant uses of a group. Similarities in floristic composition of the two groups can be attributed to widespread and common species. Floristic variation and diversity in homegardens were strongly related to homegarden geographical location, personal preference, and cultural background of the owners.     

The Analysis of Homegarden Plant Diversity at the Mongolian Household Level in Horqin Sandy Land——A Case Study in Horqin Left Wing Real Banner of Inner Mongolia

In order to show the function of agricultural protection of biodiversity at the level of homegarden, comparative analysis was operated between 20 farmer households through random sampling and farmers recommended in Horqin Left Wing Real Banner Tongliao city Inner Mongolia Autonomous Region and 10 farmer households of the Han nationality in the neighborhood. Thirty sampling plots of homegardens are investigated. The result indicates there are 100 homegarden plants in Bashou village, 84 in Hariwusu livestock farm, and 87 in Gongjihao village. It involves the cultivated and wild vegetables, fruits, and plants used for ornamental, medicine and forage. The comparative analysis of species richness demonstrates, among these villages the species richness of Bashou village is highest, while Hariwusu livestock farm is lowest. The former village contributes greatly to the conservation of plant biodiversity. These differences result from their respectively different natural conditions, homegarden areas, homegarden history, homegarden management conditions, traditional knowledge and culture understanding of homegarden manager, local farmers and herdsmen on homegarden plants.The homegarden plants from the three investigated villages are cataloged preliminary in the end of the paper.     

科尔沁沙地蒙古族户级水平庭园植物多样性分析——以内蒙古通辽市科尔沁左翼后旗的研究为例

为了表明农户庭园在户级水平上对农业生物多样性保护的作用,在内蒙古通辽市科尔沁左翼后旗采用随机抽样和农户推荐选择20个农户,同时在邻近地区的汉族地区选择10个农户作为对比分析。在此基础上对其家庭庭园采用典型取样法设立30个样方进行调查。结果表明：巴首嘎查庭园植物有100种、哈日乌苏种畜场共有84种、公济号村有87种,包括栽培及野生蔬菜、水果、观赏、药用、饲用等植物。三个村庄庭园植物物种丰富度分析比较发现巴首嘎查的物种丰富度相对最高,而哈日乌苏种畜场的相对最低,反映巴首村对庭园物种多样性保护的贡献相对最大。这些差异是由于自然条件、庭园面积、庭园历史、庭园管理条件及庭园管理者、当地农牧民对庭园植物的传统知识和文化的认识的差异所造成。文末还对调查的三个村庄的庭园植物进行了初步编目。     

Agroforestry Systems as Habitat for Avian Species: Assessing Its Role in Conservation

In the current scenario of rapid conversion of tropical forests into human-dominated activities landscape, the present study was undertaken to understand the role of existing agroforestry systems in conservation of avian species. Three types of agroforestry systems namely tea gardens, homegardens and agrisilviculture were selected in the Brahmaputra North Bank Landscape of Assam, northeast India for the study. A total of 468 point counts revealed 164 bird species belonging to 51 families and 18 orders across all the three different types of agroforestry systems. Tea gardens showed significantly higher bird species richness followed by homegardens and agrisilviculture systems. As per IUCN, four species were categorized as Near Threatened and one species was categorized as Vulnerable. Out of 164 species recorded, 68.3% species were residents, 30.5% species were winter visitors and remaining were summer visitors (1.2%). Majority of the species (45.7%) were common to all the three types of selected agroforestry systems. The feeding guilds revealed that most of the species were insectivorous (50.0%) in habit. A total of 167 tree species belonging to 54 families and 24 orders was recorded across all the three different types of agroforestry systems. The highest tree species richness was recorded in the homegardens (160), followed by agrisilviculture systems (19) and least in tea gardens (11). No statistically significant correlation was found among bird species richness and patch size, tree species richness and number of bird species individuals. The selected agroforestry systems have provided shelter, nesting space, feeding and foraging grounds for birds during the winter season. This data can be useful for the policy makers, tea garden managers, homegarden owners for framing conservation policies of avian species in an era of natural wildlife habitat loss and degradation.     

Can Homegardens Conserve Biodiversity in Bangladesh?

In managed landscapes, tree-dominated habitats often show promise for biodiversity conservation. In Bangladesh where natural forest cover is less than 10 percent, homegardens, which are maintained by at least 20 millions households, represent one possible strategy for biodiversity conservation. This study investigated the floristic and structural diversity of 402 homegardens from six regions across southwestern Bangladesh. All plants were censused, totaling 419 species (59% native), including six IUCN Red Listed. The median homegarden (800 m²) contained a mean of 34 species. Each region contained a mean of 293 species in a mean of 67 homegardens. A total of 49,478 individuals (107 per homegarden and 1003 per hectare) of trees and shrubs were counted from 45.2 ha total sampled area. Thus, significant botanical richness was exhibited in the homegardens across southwestern Bangladesh. However, most species were rare: 82 percent of all species including 189 native were found in 50 or fewer homegardens, and 63 species (36 native) were found in only one or two homegardens. Sixty percent of all tree and shrub species had 50 or fewer individuals each. Thus, whereas richness across the landscape was high, serious effort must be made to increase the populations of most species. We propose three main conservation activities: (1) awareness building; (2) protection of existing individuals of rare species; and (3) propagation. Overlaying all of these activities is the inclusion of local communities in the process, who were the ones to retain these species in homegardens in the first place, and the stakeholders who will determine whether homegardens indeed act as long-term repositories to biodiversity conservation.     

科尔沁沙地蒙古族和汉族庭园植物群落垂直结构与种类组成比较——以内蒙古科尔沁左翼后旗为例

在内蒙古通辽市科尔沁左翼后旗蒙古族居住地区采用随机抽样和农户推荐选择30个农户,同时在邻近地区的汉族选择了10个农户作为对比分析。庭园样方取样为整个庭园面积,设立40个样方进行调查。结果表明,内蒙古通辽市科尔沁左翼后旗蒙古族庭园和邻近地区汉族庭园植物垂直结构主要有0~1 m、1~2 m、2~5 m、5~10 m、10 m等五类,其中不论是小规模庭园还是大规模庭园,5 m以下的阶层占优势;两个民族庭园植物种植模式研究结果阐明科尔沁左翼后旗蒙古族与邻近汉族相比,目前很少栽培观赏植物,仍停留在与日常生活相关的蔬菜植物栽培的水平上,而邻近的汉族已开始注重栽培美化环境的庭园植物。此外,本研究运用MVSP统计软件分析庭园类型表明科尔沁左翼后旗蒙古族庭园主要有4种类型,邻近的汉族庭园有3种类型,并且当地蒙古族与邻近的汉族庭园有所差异,这些差异是由两个民族间农耕文化传统以及畜牧业植物文化差异、庭园面积、庭园历史及庭园管理水平、传统植物利用知识的差异所造成。     

Cultural homegarden management practices mediate arthropod communities in Indonesia

Tropical forest loss and transformation to agroecosystems have serious impacts on biodiversity, associated ecosystem services and the livelihood of local people. The high crop plant biodiversity and low intensity management in many homegardens could play an important role in the preservation of biodiversity in modified landscapes, as well as sustain food security of low income households. In this study, we focused on the role of the owner’s cultural background as migrants (from the island of Java) or non-migrants (local residents) for homegarden characteristics, such as size, management diversification, and crop species richness, and their effect on arthropod communities in Jambi province, Indonesia. Vane traps, pitfall traps and sweep netting were used to survey the arthropod communities, in particular bees and wasps, in 24 homegardens. Our results show that the native Jambi locals used a smaller number of management practices and had smaller homegardens than the Javanese transmigrants, whereas crop species richness did not differ. Management diversification and crop species richness were positively related to arthropod abundance as well as species richness of bees and wasps, presumably due to the enhanced homegarden heterogeneity. Our findings suggest that the cultural practices of migrant versus non-migrant land-use managers, which is usually neglected in agroecology, can be a major determinant of management practices shaping community structure and services of beneficial arthropods.     

Homegardens in Smallholder Farming Systems: Examples From Bangladesh

Homegardens are integral part of rural households in Bangladesh. The present study examines some physical, biological, and socioeconomic characteristics of 32 homegardens randomly selected from four villages representing different agro-ecological conditions, variable population densities, and market opportunities. The study results suggest that large numbers of plant and animal species occupy homegardens, and their composition and intensity of cultivation vary directly with the household physiologic density and access to urban markets, and inversely with environmental constraints to agriculture. Homegardens form the activity space for household women and children, who perform most homegarden farming tasks. Uses of home generated inputs at no or low cost make homegardens economically more efficient and sustainable compared to non-homegarden rice farming. In the context of the intensive subsistence agriculture patterns that dominate Bangladesh, homegardens contribute significantly to smallholder household income.     

The Vertical Structure and Composition of Homegarden Plants in the Horqin Sandy Land of the Mongols——A case study in the Horqin Juun Garon County of Inner Mongolia

Used the random sampling and recommendation, 30 households of Mongolian in Horqin Juun Garon Country were selected to compare with 10 households of Han nationality which lives in the region of nearby. Forty sampling plots of homegardens were investigated. The results indicates that the perpendicular structure of homegarden plants in Mongolian and Han nationality can be classified to 0-1m, 1-2m, 2-5m, 5-10m, and higher than 10m. The perpendicular structure lower than 5m is predominance in both large and small homegardens. Comparing the cultivation pattern in two nationality, Mongolia still stay in the level of vegetable cultivation which relaled to the daily life, the plants for view and admire are very few at present. But Han nationality have started attaching importance to the view and admire homegarden plants. Besides, this research applied the software MVSP to analyze the type of homegardens and indacates that the homegarden of Mongolian in Horqin Juun Garon Country have four categories, and Han nationality have three categories. The results indicate that there are many differences between Mongolian and Han nationality. This is caused by the differences between the two nationalities in traditional farming culture, animal husbandry culture, the area of homegarden, the history of homegarden, the management of homegarden, and the traditional botanical knowledge on plant species utilization.     

Distribution of Agrobiodiversity in Home Gardens along the Corrientes River,Peruvian Amazon

Distribution of Agrobiodiversity in Home Gardens along the Corrientes River, Peruvian Amazon. This paper examines crop species diversity in home gardens of traditional communities along a remote tributary in northeastern Peru. A large-scale survey was conducted of 300 gardens in 15 villages along a 150 km reach of the Corrientes River. Study villages vary notably in community size, ethnicity of residents (Achuar, Urarina, mestizo), and proximity to the regional town (Trompeteros) as well as to oil wells. Gardens were inventoried and interviews conducted with garden tenders to provide data on socioeconomic characteristics of the household and contextual conditions. Multiple regression analyses identified the determinants of species diversity. Results indicate high crop diversity—the highest yet reported for sites in the Amazon basin—particularly among the Achuar people. Garden species diversity is greatest in larger villages and, surprisingly, in those villages located nearer to the oil company. Within villages, households with larger land holdings (and gardens), more in-house labor, and garden tenders who are older and female tend to have more diverse gardens. A small number of households (15/300) were found to hold exceptional diversity, often older and land-wealthier households located on the outskirts of villages. These farmers held, on average, three times the number of species as a typical village garden and 60% of all species encountered in the study.     

Comparison of the Homegardens of Eight Cultural Groups in Jinping County,Southwest China1

Comparison of the Homegardens of Eight Cultural Groups in Jinping County, Southwest China. Species growing in 124 homegardens in 15 villages inhabited by 8 cultural groups living in Jinping County, southwest China, were recorded, together with information on the uses of the species and other features of the gardens. Data were gathered using key informant interviews, participatory observation, and ecological sampling. The results showed that production of food for domestic use was the main function of the gardens. Other uses included plants for income generation, household-level construction, local health care, and for ecological purposes (confined to higher altitude homegardens). The primary floristic variation in the gardens was related to climatic change with altitude, with variations in the use of the gardens to grow plants for local healthcare being also significant. Homegardens can be clustered into two groups based on floristic composition—lower altitude gardens (including Dai, Zhuang, Homg, and Lahu) and higher altitude gardens (including Yao, Yi, Hani, and Han). Both cultural conservatism and a readiness to adapt to new economic conditions are reflected in the characteristics of the gardens. Homegardens maintain considerable conservation value as repositories of several species of endangered plants and several species of medicinal plants that are over-collected in the wild.     

Density,habitat associations and conservation status of Gekko gecko (Tokay gecko) in human-dominated landscapes around Nameri Tiger Reserve,Assam, India

This study conducted from January to June 2018, attempts to determine the density, habitat preferences and attitudes of people towards Gekko gecko and its impact on the conservation of this species in human-dominated landscapes in Sonitpur district, Assam. Eight villages at different distances from Nameri Tiger Reserve were chosen for the study. The line transects analyzed using DISTANCE software estimated a density of 7.99 individuals ha^?1 in fringe villages of Nameri Tiger Reserve which also had higher number of host tree species diversity with higher basal area and density as compared to that of villages distant from Nameri Tiger Reserve. Gekko gecko was sighted on a total of 30 trees (6 species, 2 families), the highest being Ficus rumphii (40%). Maximum sightings of Gekko gecko was done on trees (67%). The occurrence of Gekko gecko was highly influenced by distance from forest (12%), followed by source of income (11%) and gender (4%). The majority of the respondents (53.54%) revealed that Gekko gecko occurred naturally in the homegardens implying that homegardens provided the habitat that can support the populations of Gekko gecko. But 46.45% of the respondents reported that they were adopted (62.16% in villages distant from Nameri Tiger Reserve), which raises serious concerns about the conservation of Gekko gecko in homegardens. Though, majority of the people knew that it is illegal to trade Gekko gecko, the financial benefits of its trade is very alluring. To make homegardens more favourable for the survival of Gekko gecko there should be strict law enforcement, upgradation of the species in the IUCN Red List and options for alternative livelihood.     

Effect of size and altitude on soil organic carbon stock in homegarden agroforestry system in Central Himalaya,India

Homegarden agroforestry system has potential to sequester carbon while simultaneously producing agriculture yield and tree products. This study analyzed relationship between homegarden size and soil organic carbon stock (SCS) along an altitudinal gradient in Central Himalaya, India. Homegardens were selected at four altitudes (very low, low, mid and high) and categorized into three size classes viz. small, medium and large. Soil samples from surface (0–15 cm) and sub surface soils (15–30 cm) were collected seasonally and analyzed. Results indicated that SCS ranged between 22.56 and 81.51 t C ha⁻¹ and increased with increasing altitude for small homegardens. For medium and large homegardens, it increased up to mid altitude and then decreased in high altitude homegardens. At each altitude, maximum SCS (38.56–66.16 t C ha⁻¹) was recorded for medium sized homegardens except at high altitude where it was maximum (66.01 t C ha⁻¹) for small homegardens. Seasonal variation in SCS showed inconsistent pattern along the altitudinal gradient. The differences in SCS due to size and altitude recorded in the present study are possibly caused by distinct quality of plant material and management practices.     

Plants in traditional home gardens: richness,composition, conservation and implications for native biodiversity in Benin

Home gardens have received increasing attention and have been insistently presented as hotspots for agro-biodiversity over the last decades. However, apart from their exceptional high plant species diversity, there is little quantitative evidence of the effectiveness of plant species conservation in home gardens. This study examined this issue by assessing (i) the size and membership of garden flora and the contribution to the maintenance of the national flora, (ii) how home garden flora connects to the larger ecosystem it belongs to and (iii) the conservation status of plant species at the home garden level. 360 home gardens distributed in three agro-ecological zones and nine phyto-geographical districts in Benin were visited and inventoried. Diversity parameters at different taxonomic levels were calculated. Species accumulation and spatial occupancy, multivariate methods and rarity index were also used for data analysis. Findings showed that the 360 studied home gardens hosted up to 14.21% of plant species and 44.32% of plant families of the national flora. Home garden flora was constantly dominated by exotic plant species but strongly connected to their surrounding ecosystems, being composed of at least 60% of plant species from their phyto-geographical districts. Finally, home garden plant species were mostly rare and threatened at the home garden level. In this study, we acknowledge the contribution of home gardens to the maintenance of plant species diversity at regional and global levels than local level. Based on the observed prevalence of exotic species, HG effectiveness in sustainably conserving native plant species biodiversity remains questionable.     

内蒙古通辽市库伦旗蒙古族庭园植物农业生物多样性分析——以芒汗苏木毛敦塔拉嘎查为例

庭园是形成和保存农业生物多样性的基本单位,也是野生植物和栽培植物聚集的场所。在农村,庭园的主要作用是提供日常生活所需,还可产生收入。庭园中不仅存在较高的生物多样性,而且庭园也有很多社会、文化、生态方面等功能。该研究针对通辽市库伦旗芒汗苏木毛敦塔拉嘎查蒙古族,采用随机抽样和农户推荐的方式选择了11个农户,以农户的整个庭园面积为样方,设立11个样方进行农业生物多样性分析,并用漫谈式访谈和半结构调查方法进行庭园植物及其经济效益调查。结果表明:毛敦塔拉嘎查蒙古族庭园植物物种丰富度较高,庭园植物共有96种,包括栽培及野生的植物蔬菜类33种、水果用19种、观赏用20种、饲料用8种、药食兼用5种、其它用途类16种,其中有些种类具有多种用途;毛敦塔拉嘎查各农户庭园植物的多样性随着庭园类型及庭园管理者的特征而不同;庭园面积大且种植大量经济作物的庭园经济效益高;据调查当地庭园的经营模式具有生态种植型、综合经营型、庭园养殖型三种类型。这些庭园植物不仅对当地农牧民的生活具有广泛作用而且对农业生物多样性保护具有深远意义。     

Species composition, diversity, and use of homegardens among three Amazonian villages

Homegardens represent a traditional form of land use common in tropical regions of the world. Species composition, structure and function of homegardens may be influenced by ecological, socio-economic and cultural factors. The three villages in the Peruvian Amazon in which homegardens were studied differed in terms of cultural background, distance to urban markets and the influence of tourism. Data were collected on species composition, abundance and use of plants in the homegardens. Comparison of the three villages revealed that tourism had the greatest impact on species composition, diversity and use of plants in homegardens.     

Urban Domestic Gardens (IV): The Extent of the Resource and its Associated Features

Domestic (‘private’) gardens constitute a substantial proportion of ‘green space’ in urban areas and hence are of potential significance for the maintenance of biodiversity in such areas. However, the size and nature of this resource and its associated features are poorly known. In this study, we provide the first detailed audit, using domestic gardens in the city of Sheffield as a model study system. Domestic gardens, the mean area of which was 151 m², cover approximately 33 km² or 23% of the predominantly urban area of the city. The smaller gardens contribute disproportionately to this total because, although individually they add little, they are large in number. Conversely, the regions of the city with proportionately more garden area contribute most to the total garden area of the city, although such regions are limited in number. Based on the findings of a telephone based survey, 14.4% of dwellings with gardens were estimated to have ponds, 26% to have nest-boxes, 29% to have compost heaps, 48% to hold trees more than 3 m tall, and 14% of dwellings were estimated to be home to one or more cats. Whilst the absolute frequency of these features is low to moderate, by extrapolation they nonetheless yield estimates for domestic gardens in Sheffield of a total of 25,200 ponds, 45,500 nest boxes, 50,750 compost heaps, 360,000 trees, and a population of 52,000 domestic cats. These results are considered in the context of the role of gardens in urban areas as habitats for wildlife and the implications for housing policy.     

不同生境条件与管理方式对茶园蜘蛛群落结构及多样性的影响

蜘蛛在茶园的生态控制和生物防治中起到重要的作用,为了解不同生境条件和管理方式的茶园蜘蛛群落结构差异和多样性变化,于2011年3月份—2011年10月份,运用振落承接和过筛法对3种不同类型茶园的蜘蛛群落组成与多样性进行了调查。结果表明:(1)3种类型茶园蜘蛛群落组成:3种类型茶园蜘蛛群落在科、属、种的组成及个体数量上,均表现为有机茶园高,无公害茶园次之,普通茶园低,且在物种数和个体数存在显著差异。管巢蛛科和狼蛛科是3种类型茶园的优势类群,球蛛科、跳蛛科、狼蛛科、皿蛛科的物种优势度大于10%。(2)蜘蛛群落物种多样性的多重分析结果表明,有机茶园蜘蛛群落的个体数、物种数、物种多样性指数、物种丰富度指数和均匀度指数均高于无公害茶园和普通茶园,普通茶园最低,且达到显著水平(P0.05)。(3)多元数据分析结果表明,有机茶园蜘蛛群落组成与普通茶园差异较大,无公害茶园与普通茶园蜘蛛群落组成差异较小;3种类型茶园的茶丛蜘蛛群落个体数、物种数及物种多样性指数、丰富度指数和均匀度指数均高于地表,且表现为机茶园多,无公害茶园次之,普通茶园最少。蜘蛛的功能群采集发现,在3种茶园中结网蜘蛛少,而主要是游猎蜘蛛。(4)不使用化学农药的茶园,因其周边生境结构复杂(竹林、小灌木及杂草),植被丰富,形成植被缓冲带,改善了茶园小气候环境,增加了茶园土表覆盖度,可明显提高茶丛和地表游猎蜘蛛的物种数和个体数量。综合研究结果表明,在生态条件好、干扰少的有机茶园中的蜘蛛物种数量、群落多样性明显高于受损生态系统和人为干扰强的普通茶园。
