The aim of this study was the description of crop diversity, structure and management of homegardens in Central Sulawesi and their classification. In 30 homegardens randomly selected from three villages adjacent to the Lore Lindu National Park, species diversity and abundance were assessed and the Shannon index was calculated. Overall 149 crop species were identified, mainly fruit, vegetable, spice, or medicinal plants. The number of vegetation layers differed depending on age and size of homegardens. Cluster analysis of crop species composition was used to classify different garden types. Not only the spectrum of species cultivated in the homegardens but also the occurrence of these garden types was different among the three villages. This finding was supported by Sorensen's coefficient. Homegardens from one village, mainly inhabited by transmigrants, contrasted strongly with those from the other two. A markedly lower number of crop species was cultivated there, and species composition was clearly different. The number of crop species and species composition found in homegardens may be attributed to socio-economic conditions of garden keepers as well as to soil quality. Both productivity and sustainability can be enhanced, e.g., by improved soil fertility management such as applying available farm yard manure."],["dc.identifier.doi","10.1023/B:AGFO.0000049433.95038.25"],["dc.identifier.isi","000225324700006"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/48985"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","1572-9680"],["dc.relation.issn","0167-4366"],["dc.title","Crop diversity and classification of homegardens in Central Sulawesi, Indonesia"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Nevertheless, its diversity has not been studied in detail. A survey covering 339 farm households and eight districts was conducted in the major yam growing regions of Southern Ethiopia to investigate the diversity and distribution of yam landraces using structured and semi-structured questionnaires. A total of 37 named landraces were recorded, with a range from one to six (mean 2.9) on individual farms. Farmers' decisions regarding the number and type of landraces maintained was influenced by tolerance of the landraces to drought, their maturity time and market demand. Most landraces had limited abundance and distribution, and only a few dominant landraces were widely grown. There was also variation amongst districts with respect to diversity, distribution and abundance of the landraces found. In the majority of the localities surveyed, farmers reported a decreasing trend in the number of landraces maintained on individual farms and in the overall yam production. Besides, in those limited areas where yam production is expanding, farmers are increasingly relying on a few selected landraces that mature early. Findings of this study suggest that local farmers in Wolayita and Gamo-Gofa zones maintain considerable yam diversity that remains to be further explored for sustainable utilization and conservation of the available genetic resources."],["dc.identifier.doi","10.1007/s10722-007-9219-4"],["dc.identifier.isi","000252296200013"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/55068"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","0925-9864"],["dc.title","Diversity, distribution and management of yam landraces (Dioscorea spp.) in Southern Ethiopia"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The objective of this study was to assess genetic variation using amplified fragment length polymorphisms (AFLP) in two species of the tropical legume genus Stylosanthes Sw. Annual, S. humilis (2n = 20) and perennial, S. viscosa (2n = 20) are found throughout tropical America, and are sympatric for much of their range of distribution. One hundred and eleven accessions, covering a wide geographical range, were selected for AFLP analysis. Binary data matrices derived from DNA banding patterns were analysed using the software programs NTSYS-PC and ARLEQUIN. Several accessions were found to be misidentified. Of the S. humilis accessions, the overall average similarity value was (0.72) slightly higher than the value obtained for S. viscosa (0.67). Cluster analysis and principal coordinate analysis grouped accessions from both species by geographical origin, with a few exceptions. Analysis of molecular variance (AMOVA) in S. humilis revealed 59.4% of the variation among groups formed from the cluster analysis. This was highly significant (P < 0.001). For S. viscosa AMOVA also revealed more variation among than within groups (66.5%). This was also highly significant (P < 0.001).

There was a positive correlation between pastoralists' preference ranking of forage species and crude protein content of the species. IEK of men and women was complementary. The process of rangeland degradation was described as shortage of grass and decrease in density and frequency of highly palatable grass species, leading to low milk production and reduced conception rates in cows.

However, the young generation in the area had not only limited knowledge but also showed less interest to learn and apply the traditional resource management strategies. Therefore, there is high need to perpetuate, document and use this IEK for sustainable development.
