“…Homegardens closer to markets may be more engaged in the commercialization of only a few species such as highly productive mangos (Major et al, 2005). However, a commercial focus does not automatically result in a decline in overall homegarden diversity as their primary purpose often remains subsistence as has been demonstrated by Trinh et al (2003) and Kabir and Webb (2009). Evidence in Amazonia about the relationship between distance to market and diversity of homegardens has been quite mixed and complex with Major et al (2005) finding that diversity is higher further away from markets, while Heckler (2004) and especially Wezel and Ohl (2005) have found that agrodiversity is higher closer to the market.…”

A link between market proximity and homegarden agrodiversity has frequently been considered in homegarden research, with findings demonstrating both a decline in diversity with increased proximity to a market as well as maintenance of the diversity close to a market (Fernandes and Nair, 1986;Soemarwoto, 1987;Rico-Gray et al, 1990;Lamont et al, 1999;Wezel and Ohl, 2005;Kabir and Webb, 2009).…”

Urban agriculture, including urban homegardens, is vital for urban survival of many people in various cities around the world, including those in the Amazon region of Brazil. These spaces, through daily praxis, become important for incidental agrodiversity conservation as food plants are cultivated and their plant material circulated. Utilizing data from a year-long intensive qualitative study of 25 rural-urban migrant households, this article considers the diversity of plant material in urban homegardens in the Amazonian city of Santarém, Pará, Brazil. The purpose of the study was to understand the social systems that maintain cultivated plant diversity in homegardens. Our objectives in this article are twofold: a) to demonstrate that plant agrodiversity in homegardens persists in a setting which is located 'at the market'; and b) to document the ways in which flows of plant material help maintain this agrodiversity.Keywords: Homegardens.

Esses espaços, por meio da prática cotidiana, tornam-se importantes para a conservação incidental da diversidade agrícola, enquanto áreas para cultivo de plantas alimentícias e de circulação de plantas. Utilizando dados de um ano de estudo qualitativo intensivo de 25 residências de migrantes rurais-urbanos, o artigo aborda a diversidade de plantas nos quintais urbanos na cidade amazônica de Santarém, Pará, Brasil. O propósito do estudo foi compreender os sistemas sociais que mantêm a diversidade de plantas cultivadas nos quintais. Nosso objetivo neste artigo é duplo: a) demonstrar que a agrodiversidade de plantas nos quintais persiste em um cenário que se situa 'no mercado'; e b) documentar as maneiras pelas quais os fluxos de material vegetal ajudam a manter essa diversidade agrícola.Palavras-chave: Quintais.

These species are attractive globally because they provide multipleuse options, quick production of edible crops, income-generating opportunities and availability of planting materials (Rico-Gray et al 1990;Kumar and Nair 2004;Albuquerque et al 2005;Nair and Kumar 2006).…”

SUMMARYHomegardening is a traditional agroforestry practice in Bangladesh. Diverse species composition in a complex structure is a characteristic feature of Bangladesh homegardens. This study investigated the floristic and structural characteristics of homegardens from 402 randomly selected households in southwestern Bangladesh. A total of 419 species in 109 families were recorded. Fifty-nine per cent of all species were native to the Indian Subcontinent, including six IUCN Red-Listed for Bangladesh. Seventy-five per cent of all species were planted. Trees and herbs predominated and accounted for about 71% of all the identified species. The median homegarden of 800 m 2 contained 34 species and 107 individual trees and shrubs. The recorded species were used for nine different purposes. In general, native species were more commonly used for all purposes except food, commerce, and fibre. The vertical architecture of the homegarden was complex. Common species were consistent with the general floristic profile reported from other tropical homegardens. Homegardens provided year-round subsistence and economic benefits from balanced adoption of multiple-use plants in different strata on limited homestead space. The results suggest considerable potential for the establishment and development of homegardening systems for the sustainable supply of subsistence livelihoods, while contributing to biodiversity conservation.

“…is essentially a herbaceous perennial plant which distributes widely in cool and humid climate areas. Based on the different colors of extracts and morphological characteristics, P. bivalvis appears in four varieties which are purple, purple-magenta, red, and yellow [2,3,4]. The identification of these varieties primarily bases on the difference between their phenotypes, such as the leaf shape and difference among colorants extracted from them.…”

Abstract. An investigation on the current usage status and experience in using Peristrophe bivalvis (L.) Merr. was conducted in the mountainous region of Northern Vietnam. Five varieties were collected and recorded as a source of foodstuff-dyeing and medicinal plants on indigenous knowledge of ethnic minorities in the study area, of which, three varieties were dyed purple, one red and one yellow-orange; with two varieties being used for the treatment of haemoptysis, dysentery, liver disease, kidney failure, and jaundice. Two extraction methods using organic solvents and aqueous solvent were applied to spectrophotometrically investigate the phytochemical contents of Peristrophe bivalvis varieties. Accordingly, the coloration components of Peristrophe bivalvis varieties were contributed by a complex compound of photosynthetic pigments, anthocyanins, flavonoids. Also, the total phenolics, total flavonoids and effect of extraction methods, dissolved solutions (water and methanol) on these contents were assessed. Besides, screening antioxidant capacity of Peristrophe bivalvis varieties was assayed by 1,1-diphenyl-2-picrylhydrazyl (DPPH) method which showed stronger radical inhibition of organic extractions than that of aqueous extractions. The results of determination of phytochemicals and antioxidant capacity support the knowledge and experience in using Peristrophe bivalvis varieties as natural dyeing production for food and pharmaceutical industry.
