    Village committees, as grassroots spontaneously formed by rural collective members in China’s hierarchy system, play an irreplaceable role in the management of rural public affairs. Based on the filed survey dataset taken from three pilot counties/districts in Sichuan province, we explored the significant role that village committees played in farmers’ withdrawal from rural homesteads (WRH).

    How much organic C can a region naturally store in its ecosystems? How can this be determined, when land management has altered the vegetation of the landscape substantially? The answers may lie in the soil: this study synthesized the spatial distribution of soil properties derived from the state soils geographic database with empirical measurements of old-growth forest ecosystem C to yield a regional distribution of potential maximum total-ecosystem organic C stores.

    Recent experience has shown that as countries get richer, nutritional status does not necessarily improve. In a recent article in the journal The Lancet, IFPRI researchers and others explain that creating the right conditions for nutritional advances often requires political action. The feature article in this issue of Insights looks at how some developing countries and regions—Ghana, Peru, Thailand, and the state of Maharashtra, India—have made nutrition a political priority and how they’ve turned political commitments into widespread changes on the ground.

    This paper reports on the remarkable results we achieved with a novel, inexpensive collecting method, i.e. band-shelter trapping, during a survey conducted in 25 urban parks and greenbelts in the Beijing metropolitan area from April to October during 2007–2009. The trap was made of 3-cm wide, opaque, plastic fiber, wrapped around willow tree trunks (Salix spp.) at a height of 1.5 m height. Traps were checked every two weeks.

    Participatory mapping of local land use as the basis for planning and decision-making has become widespread around the globe. However, still relatively little is known about the conceptual underpinnings of geographic information produced through participatory mapping in given cultural and linguistic settings. In this paper, we therefore address the seemingly simple question of what is (not) represented on maps through an exploratory case study comparing land use categories participants represented on sketch maps with categories elicited through more language-focused ethnographic fieldwork.

    From 2009 to 2014 a nationwide effort was made to document, collect, conserve, and characterize wheat landraces grown by Turkish farmers. Spike samples were collected from more than 1600 farmers from 59 provinces, planted as single-spike progenies, and classified into species, subspecies, and botanical varieties (or morphotypes). Altogether, 95 morphotypes were identified representing three species and six subspecies: einkorn wheat (Triticum monococcum L.), emmer wheat [T. turgidum subsp. dicoccon (Schrank) Thell.], cone wheat (T. turgidum subsp. turgidum), durum wheat [T. turgidum subsp.

    Guatemala, Mexique

    Based on a comparative case study of four community forestry enterprises in Guatemala and Mexico, we examine the relationship between user group characteristics and state allocation of tenure bundles. Using Schlager and Ostrom's four levels of tenure bundles and collective action theory, we illustrate how tenure bundles and collective action costs interact to either promote or create disincentives for conservation and communal economic benefits.
