This study was designed to assess the access of Nepalese farmers to the training and extension service, gender division on agricultural work, and factors affecting agrobiodiversity management activities. A total of 2,817 respondents were interviewed at different locations throughout Nepal. The information was collected using the mWater surveyor. Descriptive and inferential analyses were done. The respondents having received training in agriculture were significantly higher among elite, educated, and agricultural households. Access to extension facilities was significantly determined by the type of household, ethnicity, occupation, and education of respondents. Male domination in the choice of crops, land preparation, and seed selection were significantly higher in male-headed households, marginalized groups, and agricultural households. However, females were more likely to be involved in seed sowing. The male domination in male-headed households were significantly higher for applying fertilizers, weeding, irrigation, and pest control. Among elite ethnic groups, domination of males was significantly higher for fertilizer application. The role of the male in agricultural households was significantly higher in all aspects. One unit increase in the area increased the likelihood of male involvement in irrigation by 30%. The males are likely to be more involved in harvesting, sales of products, and control of income. Elite and educated respondents coupled with access to training practiced more crop rotation compared to the rest. The likelihood of practicing intercropping and mixed cropping was influenced by extension facilities and training facilities. Elite groups and farmers with extension facilities tended to practice more agroforestry. So, the types of households, education, and ethnicity have a key role in the gender differentiation in agriculture operation. Moreover, training and extension facilities help a lot in the conservation and practice of agrobiodiversity. There is an urgent need in improving the women's role and overall management of the agricultural landscape.

Abstract We investigated factors affecting nest success of songbirds in riparian forest and buffers in northeastern Missouri. We used an information-theoretic approach to determine support for hypotheses concerning effects of nest-site, habitat-patch, edge, and temporal factors on nest success of songbirds in three narrow (55–95 m) and three wide (400–530 m) riparian forests with adjacent grassland-shrub buffer strips and in three narrow and three wide riparian forests without adjacent grassland-shrub buffer strips. We predicted that temporal effects would have the most support and that habitat-patch and edge effects would have little support, because nest predation would be great across all sites in the highly fragmented, predominantly agricultural landscape. Interval nest success was 0.404, 0.227, 0.070, and 0.186, respectively, for Gray Catbird (Dumetella carolinensis), Northern Cardinal (Cardinalis cardinalis), Indigo Bunting (Passerina cyanea), and forest interior species pooled (Acadian Flycatcher [Empidonax virescens], Wood Thrush [Hylocichla mustelina], Ovenbird [Seiurus aurocapillus], and Kentucky Warbler [Oporornis formosus]). The effect of nest stage on nest success had the most support; daily nest success for Gray Catbird and Indigo Bunting were lowest in the laying stage. We found strong support for greater nest success of Gray Catbird in riparian forests with adjacent buffer strips than in riparian forests without adjacent buffer strips. Patch width also occurred in the most-supported model for Gray Catbird, but with very limited support. The null model received the most support for Northern Cardinal. Riparian forests provided breeding habitat for area-sensitive forest species and grassland-shrub nesting species. Buffer strips provided additional breeding habitat for grassland-shrub nesting species. Interval nest success for Indigo Bunting and area-sensitive forest species pooled, however, fell well below the level that is likely necessary to balance juvenile and adult mortality, which suggests that when riparian forests are located within agricultural landscapes, the potential even for wide riparian forests with adjacent buffer strips to provide high-quality breeding habitat is severely diminished for some species.

The survival of habitat-dependent fauna within agricultural mosaics depends on their ability to occupy remnant habitat patches and move through the modified landscape. In north-west Victoria, Australia, less than 10% of the pre-European extent of Belah Casuarina pauper woodland remains intact due to agricultural development. The White-browed Treecreeper Climacteris affinis, is a small, insectivorous passerine that, in this region, preferentially inhabits Belah woodland. To assess the ability of C. affinis to persist in an agricultural landscape, 30 woodland sites in the Millewa landscape (34�30'S, 141�30'E) were surveyed, and patterns of patch occupancy used to examine the influence of spatial characteristics, landscape context and grazing by stock on the suitability of remnants as C. affinis habitat. Sites occupied by C. affinis were larger and less likely to be grazed by stock than vacant patches. The area-dependency of patch occupancy represents a step-threshold: C. affinis were not detected in remnants with less than 18.5 ha of Belah woodland but above this threshold, density was not correlated with patch area. Measures of patch isolation, the existence of linking linear "corridors" and tree density were not reliable indicators of patch occupancy. The presence of the species in remnants entirely surrounded by agricultural land suggests they are capable of crossing up to 450 m of cultivated land to prospect for habitat. The extensive network of linear vegetation and the numerous small remnants and scattered trees appear to facilitate movements of C. affinis in this landscape. Increasing the size of existing remnants, creating new habitat to expand the area of occupancy and maintaining landscape connectivity are priorities for the long-term management of this threatened species.
