Agricultural land use and sugarcane residue management effects on soil bacterial communities at two long-term sites in KwaZulu/Natal, South Africa, were investigated by PCR-DGGE. Land uses at site 1 were maize [M]; pre-harvest burnt sugarcane [SC]; permanent kikuyu pasture [KIK]; pine forest [PF]; wattle forest [W] and undisturbed native grassland [NAT], whereas land managements at site 2 were pre-harvest burning of sugarcane [Bto] or green cane harvesting with retention of a trash mulch [T] (with [F] or without [Fo] fertilizer additions).

Freshwater temporary wetlands are a little-studied ecosystem worldwide. They have been recognised as critically endangered in south-eastern Australia under Australian biodiversity conservation legislation. However, little has been recorded about their hydrology, functioning or biodiversity values; i.e. the factors that make them intrinsically ‘swampy’.

Lesser celandine (Ranunculus ficaria) is an ephemeral perennial introduced to North America from Europe for ornamental use. This species is becoming widespread in shady, moist woodlands and lawns in the northern United States and southern Canada. Despite its invasive attributes, lesser celandine continues to be marketed by the nursery sector. A hardy and easy plant to grow, lesser celandine has a dense compact growth form that makes it ideal for border plantings and showy flowers that make it a desirable garden species for early spring color.

Human attitude to the land is the base for existence of humanity. It widely affects everybody– environment and landscape is changed, new buildings are constructed, new villages are developed in countryside. If such recensions aren’t planned it can cause serious problems in nearest future, considering limitedness and great significance of the land as unique resource. For correction of errors in land use immeasurable resources and decennaries are necessary. Tendencies in land use development and related problems concern to all people of Latvia, especially landowners.

1. Studies of landscape change are seldom conducted at scales commensurate with the processes they purport to investigate. Landscape change is a landscape-level process, yet most studies focus on patches. Even when landscape context is considered, inference remains at the patch-level. The unit of investigation must be extended beyond individual patches to whole mosaics in order to advance understanding of faunal responses to landscape change. 2.

Nitrogen (N) deposition and land management practices can have profound impacts on the structure and functioning of alpine ecosystems occupying headwaters of major river systems. Such impacts have the potential to result in loss of N to surface waters and acidification, both of which could have serious consequences for water quality and downstream habitats.

The urbanisation process in East Jerusalem has been described as a still process, in other words, a frozen or even rarely-developed process. This paper explores the Green and Open Landscape concept as one of the dominant factors described in the Jerusalem Master Plan. This factor is one that restrains urbanisation and hinders expansion of the Palestinian neighbourhoods in East Jerusalem. Both descriptive and comparative approaches were adopted to analyse and evaluate the historical development of green spaces and open landscape concepts in East Jerusalem.

The potential for agricultural soils to act as a sink and sequester carbon (C) or a source and emit carbon dioxide (CO₂) is largely dependent upon the agricultural management system. The establishment of permanent vegetation, such as trees and grass contour buffer strips, may cause accumulation of above- and below-ground C over time, thereby acting as a sink for tropospheric CO₂. However, the effects of contour grass strips and grass-tree strips (agroforestry) on soil CO₂ emissions have not been extensively studied in row-crop watersheds in the temperate regions.

The use of landholder typologies to assist in the development of natural resource management (NRM) policies and agricultural extension programs has increased considerably in the past decade. In this paper we explore the potential of developing a typology of graziers to more effectively tailor policies and programs with the aim of improving land management outcomes.
