    Global climate change, especially the phenomena of global warming, is expected to increase the intensity of land-falling hurricanes. Societal adaptation is needed to reduce vulnerability from increasingly intense hurricanes. This study quantifies the adaptation effects of potentially policy driven caps on housing densities and agricultural cover in coastal (and adjacent inland) areas vulnerable to hurricane damages in the Atlantic and Gulf Coastal regions of the U.S.

    Decentralized stormwater management is based on the dispersal of stormwater management practices (SWMP) throughout a watershed to manage stormwater runoff volume and potentially restore natural hydrologic processes. This approach to stormwater management is increasingly popular but faces constraints related to land access and citizen engagement. We tested a novel method of environmental management through citizen-based stormwater management on suburban private land.

    The effects of intensifying the management of 15% of the Swedish forest land on potential future forest production over a 100-year period were investigated in a simulation study.

    Biomass harvesting for energy production and forest health can impact the soil resource by altering inherent chemical, physical and biological properties. These impacts raise concern about damaging sensitive forest soils, even with the prospect of maintaining vigorous forest growth through biomass harvesting operations. Current forest biomass harvesting research concurs that harvest impacts to the soil resource are region- and site-specific, although generalized knowledge from decades of research can be incorporated into management activities.

    Asia and the Pacific, for the purposes of this book, encompasses a vast territory extending from Mongolia in the north to New Zealand in the south; from the Cook Islands in the east to Kuwait in the west (Map 1). The environmental diversity of Asia and the Pacific is therefore vast, and is contrasted by the region’s coldest and hottest deserts, verdant tropical rainforests, extensive steppe, desert steppe, grassland and rangelands, mountains and plains.

    Jordanie, Asie occidentale

    The Badia constitutes about 90% of the total land area of Jordan, which is 89 342 km2. Its average annual rainfall is < 200 mm. The area with annual rainfall of 100–200 mm is considered the promising rangeland for rehabilitation. The Badia (part of the rangeland) supplies the livestock sector with about 20% of forage needs, while all the other sources provide the sector with only about 5% of forage.

    Kenya

    Rangelands in semi-arid Kenya have recently witnessed extensive land use changes. These changes can mainly be attributed to increased livestock populations and the response of the increased human population to both local and exogenous opportunities and constraints. This study was carried out in Kibwezi district of Kenya mainly inhabited by agro-pastoralists. The main objective of this study was to establish how different land use types influence soil properties in tropical semi-arid rangelands.

    Kenya

    Climate change impacts livelihoods adversely in dry-lands of Northern Kenya in terms of longer and harsher droughts, shorter and intense precipitation and floods. Climate change interlocks with peoples life-worlds differently for different reasons. Understanding the foregoing can inform and make policy more relevant. What are the Samburu peoples discernment of climate change and how have they confronted it? The paper examines the Samburu perspectives of climate change and the resulting coping, adaptation mechanisms and practice, and their prospects.

    Modern agriculture has increased food production, improved food security and reduced poverty, but farming has also caused a considerable decrease in biodiversity, primarily through land-use intensification and overexploitation, along with excessive pesticide and water use, nutrient loading and pollution. The major purpose of agriculture is to ensure sustainable food production, adequate nutrition and stable livelihoods for all.
