As the human population inexorably grows, its cumulative impact on the Earth's resources is hard to ignore. The ability of the Earth to support more humans is dependent on the ability of humans to manage natural resources wisely. Because disturbance alters resource levels, effective management requires understanding of the ecology of disturbance. This book is the first to take a global approach to the description of both natural and anthropogenic disturbance regimes that physically impact the ground. Natural disturbances such as erosion, volcanoes, wind, herbivory, flooding and drought plus anthropogenic disturbances such as foresty, grazing, mining, urbanization and military actions are con...
This open access book explores a new conceptual framework for the sustainable management of the boreal forest in the face of climate change. The boreal forest is the second-largest terrestrial biome on Earth and covers a 14 million km2 belt, representing about 25% of the Earth’s forest area. Two-thirds of this forest biome is managed and supplies 37% of global wood production. These forests also provide a range of natural resources and ecosystem services essential to humanity. However, climate change is altering species distributions, natural disturbance regimes, and forest ecosystem structure and functioning. Although sustainable management is the main goal across the boreal biome, a nove...
Study dealing with the nearly annually inundated vegetation along the edges of the Gardiken hydro-electric reservoir in western Swedish Lapland on the river Umeälven during the period 1976-1980.
"Barndomens somrar var soliga, fyllda av bad och naturupplevelser. Jag tittade på fåglar och hade mitt eget lilla zoo i trädgården. Men under ytan hände det saker. Sjöarna grodde igen, havet höll på att övergödas och ute i landskapet tystnade fågelrösterna när gifter spreds på åkrarna. Rachel Carson öppnade världens ögon med sin bok Tyst vår. Och det hon beskrev från USA hände även i Sverige. Miljö och natur blev mitt yrke." Med en stark kärlek till naturen som utgångspunkt har Henrik Ekman bevakat miljöområdet i snart ett halvt sekel. Många miljöproblem har lyckligtvis fått sin lösning, men samtidigt har nya hela tiden dykt upp. Mer komplexa och globala, svårare att lösa. Idag går sjöarna åter att bada i. Luften är frisk att andas. Miljögifternas offer har kommit tillbaka - havsörnen, gråsälen, uttern. Försurningen som hotade livet i många sjöar är under kontroll. Men världen över fortsätter jordbruk och skogsbruk att utarma den biologiska mångfalden. Och i slutet av den miljöresa som boken skildrar har klimatet blivit vår tids ödesfråga.
This book examines the diverse use of Indigenous customary rights in modern landscapes from a multidisciplinary perspective. Divided into two parts, the first deals explicitly with Sámi customary rights in relation to nature conservation in the Nordic countries and Russia from a legal and historical perspective. The authors investigate how longstanding Sámi customary territorial rights have been reassessed in the context of new kinds of legislation regarding Indigenous people. They also look at the ideas behind the historical models of nature conservation. The second part deals with the ideas and implementation of new kinds of postcolonial models of nature conservation. The case of the Sá...
