Piñon (Pinus spp.) and juniper (Juniperus spp.) expansion and infilling in sagebrush (Artemisia L.) steppe communities can lead to high-severity fire and annual weed dominance. To determine vegetation response to fuel reduction by tree mastication (shredding) or seeding and then shredding, we measured cover for shrub and herbaceous functional groups on shredded and adjacent untreated areas on 44 sites in Utah.

Ranching generally causes a progressive deforestation. Nevertheless in Mediterranean countries trees are still present in many pastoral systems, here referred to as silvopastoral systems (SPs). Trees provide products as fruits as human food, fruits or leaves as fodder, wood and firewood, environmental services like patches of soil fertility and shelter for animals, and environmental goods such as carbon sequestration, water yield and quality and reinforced biodiversity.

Little is known about the relationship between fire regimes and plant diversity in Australia's temperate grassy woodlands. The effect of fire frequency on shrubs in grassy woodland remnants across Western Sydney's Cumberland Plain was examined. Shrub species richness and composition were compared in sites that had experienced a high, moderate or low frequency of fire over the previous 20 years. Nine sites were surveyed, three in each fire frequency category; most sites, including all low-fire-frequency sites, had burnt 9-36 months prior to sampling.

Accurate a priori predictions of the sensitivity of species to vegetation management depend on an understanding of mechanisms underlying species response. To date information on where birds forage in the vegetation strata has been used to predict bird species response to vegetation change caused by livestock grazing. Profiting from this link between vegetation structural diversity and bird diversity, we test whether this variable, bird foraging height, can be used to predict the impact of a different type of habitat alteration; vegetation encroachment.

The rural proletariat constitute a substantial proportion of the global poor. Leading better lives is central to their political practices. In this paper, I aim to elaborate the political practices that attend to these aspirations, interrogations and contests. I examine existing approaches to studying political practices of the rural proletariat. I do this with a focus on India, where the National Rural Employment Guarantee Act (NREGA) is in force since 2005. I locate the program against the backdrop of neoliberal transformations in India.

The paper is based on an on-going 3-year study in the wetland communities of Kampala. The study uses participatory methods and aims to contribute to (i) the development of low-income wetland communities, (ii) to prepare these communities to become less dependent on wetlands without receding into poverty, and (iii) the better management of the wetlands. The communities in direct dependence and intimate interaction with Nakivubo wetlands are mainly poor, live and work under hazardous conditions, and their activities pose a threat to the ecological function of the wetlands.

This paper examines invasion of grasslands on Cape York Peninsula, Australia, by Melaleuca viridiflora and other woody species, and the role of storm-burning (lighting fires after the first wet season rains) in their maintenance. Trends in disturbance features, fuel characteristics, ground layer composition, and woody plants dynamics under combinations of withholding fire and storm-burning over a 3-year period were measured on 19 plots in three landscape settings. Population dynamics of M.

Woody plants have been increasing in many woodland and savanna ecosystems owing to land use changes in recent decades. We examined the effects of encroachment by the indigenous shrub Leptospermum scoparium (Myrtaceae) on herb-rich Eucalyptus camaldulensis woodlands in southern Australia. Species richness and compositional patterns were examined under the canopy of L. scoparium and in surrounding open areas to determine the species most susceptible to structural changes. Richness was significantly lower in areas of moderate to high L.

The industrialization of agriculture in western societies has often led to either intensified use or abandonment of farmland and open pastures, but experimental evidence on how the dynamics of farmed ecosystems affect space use by large herbivores is limited. We experimentally manipulated farmland patches with cutting and (early summer) low- and high-intensity domestic sheep Ovis aries grazing according to traditional use in north Norway.

This is a judgment of Supreme Court of India to check grabbing of village common land including ponds and water bodies (called in different names) by unscrupulous persons, political clout, powerful vested interests, corrupt state authorities, etc by fraudulent practices and ensure their protection and safeguard.

Paul Wolfowitz, President of the World Bank, congratulated the editorial team of National Geographic for the special issue on Africa. National Geographic has played a unique role in broadening the knowledge of the world. The World Bank partnered with National Geographic to produce a full-color wall map to raise awareness of the millennium development goals (MDGs) and to highlight each country's progress. We often hear about an Africa that is ravaged by poverty, disease and conflict. There is another face to Africa, one of hope, ambition, energy, intelligence and achievement.

Mongolia has very significant natural resources and a large part of the population is dependent on them for their daily living. The impact of the state of the environment on the living standards of herders is obvious, but also Mongolians living in the capital Ulaanbaatar have learned that air pollution, especially in winter, and other environmental problems have a deep impact on their living standards. The Government of the Netherlands has established a Trust Fund at the World Bank to support environmental activities in Mongolia.
