Data on humification is important to assessing the rate and magnitude of soil carbon (C) sequestration. Thus, this study assessed the humification degree (HLIF) of soil organic matter (SOM) and the changes in functional C groups (aromatic-C and aliphatic-C) for contrasting land use and management practices (native vegetation (NV), conventional plow-based tillage (CT) and no-till (NT) systems) in sub-tropical and tropical Brazilian environments. Experiments were conducted at Ponta Grossa (PG) in Paraná State and Lucas do Rio Verde (LRV) in Mato Grosso State of Brazil.

Early human impact (5000–3000 BC) affects mountain forest dynamics in the Alps

The resilience, diversity and stability of mountain ecosystems are threatened by climatic as well as land‐use changes, but the combined effects of these drivers are only poorly understood. We combine two high‐resolution sediment records from Iffigsee (2065 m a.s.l.) and Lauenensee (1382 m a.s.l.) at different elevations in the Northern Swiss Alps to provide a detailed history of vegetational changes during the period of first pastoralism (ca. 7000–5000 cal. BP, 5000–3000 BC) in order to understand ongoing and future changes in mountain ecosystems.

Management defines species turnover of bees and flowering plants in vineyards

Journal Articles & Books
Dezembro, 2014

Effects of land use and management on plant and pollinator diversity at the local scale have been reported. However, there is little information available on the spatial and temporal aspects of plant‐pollinator mutualist diversity relative to farm management. Information on these aspects will provide a better understanding of agri‐environment schemes in a conservation context.

Changing livelihoods and protected area management: a case study of charcoal production in south-west Madagascar

Protected areas are usually conceived and managed as static entities, although this approach is increasingly viewed as unrealistic given climate change and ecosystem dynamics. The ways in which people use land and/or natural resources within and around protected areas can also shift and evolve temporally but this remains an under-acknowledged challenge for protected area managers. Here we investigate the factors driving a rapid rise in charcoal production within a new, multiple-use protected area in Madagascar, to inform appropriate management responses.

Wasted waste—Disappearing reuse at the peri-urban interface

Safe and sustainable management of waste presents a major challenge in cities in the Global South. For decades farmers in the peri-urban interface (PUI) have used biodegradable components of urban waste as inputs into their farming practices. Evidence from Kano, Nigeria; Kumasi, Ghana; Hubli-Dharwad and Kolkata, India reveals in rare detail how urban waste reuse plays an important role in the livelihood strategies of lower-income families nd while waste farming also contributes significantly to urban food security.

method to define a typology for agent-based analysis in regional land-use research

Land use/cover change (LUCC) is often the cumulative result of individual farmer's decisions. To understand and simulate LUCC as the result of local decisions, multi-agent systems models (MAS) have become a popular technique. However, the definition of agents is not often based on real data, ignoring the inherent diversity of farmers and farm characteristics in rural landscapes. The aim of this paper is to describe an empirical method that defines an agent typology and allocates agents into the different agent types for an entire region.

Improving Farming Practices in Municipality of Gazi, Crete, Greece

Grécia

A soil survey and mapping program financed by the municipality of Gazi located on the north–central part of Crete was carried out. The studied area is characterized by a moist meso-Mediterranean climate and different degrees of land degradation from human activities. Surface soil horizons are eroded, resulting in fertility decline for olive trees, the dominant crop. According to the U.S. Department of Agriculture classification, the soils at higher altitudes are classified as Entisols xerorthents and those at lower altitudes as E. xerofluvents.

Monitoring changes in pastoral resources in eastern Sudan: A synthesis of remote sensing and local knowledge

The pastoral resources in eastern Sudan are changing under the combined impact of increasing anthropogenic activities such as clearance of natural vegetation and the effect of state policies that favour crop farming against pastoralism. Remotely sensed data are used to detect spatial and temporal changes from 1979 to 2009 in the land use/land cover (LULC) across three study sites. Areas of natural vegetation have been reduced from 26.1% in 1979 to 12.6% in 1999 and further to 9.4% in 2007. The majority of this reduction went into agricultural land.

This paper reviews the constraints and challenges of paddy farming in Taiwan. Based on those evidences, a set of eco-friendly rice farming practices raised by SRI principles are proposed from exploratory SRI trials conducted in Taiwan.

Gendered experiences of dispossession: oil palm expansion in a Dayak Hibun community in West Kalimantan

This article explores the gendered experience of monocrop oil-palm expansion in a Hibun Dayak community in Sanggau District, West Kalimantan (Indonesia). It shows how the expanding corporate plantation and contract farming system has undermined the position and livelihood of indigenous women in this already patriarchal community. The shifting of land tenure from the community to the state and the practice of the ‘family head’ system of smallholder plot registration has eroded women's rights to land, and women are becoming a class of plantation labour.
