Territorialisation and marginalisation in the forested landscapes of Orissa, India

Journal Articles & Books
Diciembre, 2013
India

Internal territorialisation or the formalisation of forest rights has led to increased state ownership in many countries, often ignoring traditional or customary tenure and land use. Because of its roots in a formal government process, the disjuncture between formal rights and local practices may be seen as unproblematic to policymakers, even though it harms the livelihoods of marginalised forest dwellers.

multi-scale accuracy assessment of the MODIS irrigated agriculture data-set (MIrAD) for the state of Nebraska, USA

Journal Articles & Books

Estados Unidos de América

Accurate and timely information about the geographic distribution of irrigated cropland is important for a range of applications including crop assessments, water resources management, drought monitoring, and environmental modeling.

Determinants of agricultural land abandonment in post-Soviet European Russia

Journal Articles & Books
Diciembre, 2013
Rusia

The breakdown of socialism caused massive socio-economic and institutional changes that led to substantial agricultural land abandonment. The goal of our study was to identify the determinants of agricultural land abandonment in post-Soviet Russia during the first decade of transition from a state-controlled economy to a market-driven economy (1990–2000). We analyzed the determinants of agricultural land abandonment for approximately 150,550km² of land area in the provinces (oblasts) of Kaluga, Rjazan, Smolensk, Tula and Vladimir in European Russia.

Optimisation of the traditional land-use system in the Angolan highlands using linear programming

Journal Articles & Books
Diciembre, 2014

This study used linear programming (LP) to analyse land-use alternatives in the traditional Umbundu farming system in the Angolan central highlands. Farmers of the region have traditionally produced maize and pulses for subsistence and vegetables and timber as cash crops. Different pasture and forest fallow rotations are used along catena production sites. The system is labour-intensive and uses animal traction. LP problems were formulated and solved for a baseline land-use alternative, improved diet alternative and maximal timber production alternative.

Interacting watershed size and landcover influences on habitat and biota of Lake Superior coastal wetlands

Journal Articles & Books
Diciembre, 2011

Coastal wetlands are important contributors to large-lake productivity and biodiversity and mediators of lake—watershed interactions. This study explores whether the size of the watershed in which coastal wetlands are embedded (a measure of strength of connection to the terrestrial landscape) influences their background condition and response to anthropogenic landuse.

Composition, structure and diversity characterization of dry tropical forest of Chhattisgarh using satellite data

Journal Articles & Books
Diciembre, 2014
India

The purpose of this study was to characterize the land use, vegetation structure, and diversity in the Barnowpara Sanctuary, Raipur district, Chhattisgarh, India through the use of satellite remote sensing and GIS. Land cover and vegetation were spatially analyzed by digitally classifying IRS 1D LISS III satellite data using a maximum likelihood algorithm. Later, the variations in structure and diversity in different forest types and classes were quantified by adopting quadratic sampling procedures.

Biosphere-atmosphere exchange of reactive nitrogen and greenhouse gases at the NitroEurope core flux measurement sites: Measurement strategy and first data sets

Journal Articles & Books
Diciembre, 2009

The NitroEurope project aims to improve understanding of the nitrogen (N) cycle at the continental scale and quantify the major fluxes of reactive N by a combination of reactive N measurements and modelling activities. As part of the overall measurement strategy, a network of 13 flux 'super sites' (Level-3) has been established, covering European forest, arable, grassland and wetland sites, with the objective of quantifying the N budget at a high spatial resolution and temporal frequency for 4.5 years, and to estimate greenhouse gas budgets (N₂O, CH₄ and CO₂).

Impact Assessment of Watershed Programme Through Remote Sensing and Geographical Information System

Journal Articles & Books
Diciembre, 2012

Impact assessment of watershed development activity assumes greater importance in present day agriculture. Considering the ability of remote sensing technology in watershed monitoring and impact assessment, a study was carried out to investigate the Impact Assessment of Karnataka Watershed Development Project (DANIDA) in Koralahallihalla Sub watershed in Sindagi taluk of Bijapur district in Northern Karnataka using satellite data of two periods i.e., IRS 1 C, LISS-III data of 30 December, 1997 (pre-treatment) and IRS P6, LISS-III data of 17 December, 2004 (post-treatment).

Monitoring land cover change in the Lake Superior basin

Journal Articles & Books
Diciembre, 2011

Consistent, repeatable and broadly applicable land use, land cover data is needed across the Lake Superior basin to facilitate ecosystem condition assessment and trend analysis. Such a data set collected regularly through time could inform and focus field monitoring efforts, and help prioritize restoration and mitigation efforts. Unfortunately, few data sets exist that are bi-nationally consistent in time, classification method, or resolution.

Socioeconomic changes and forestland development: commonalities and distinctions between the eastern and western United States

Journal Articles & Books
Diciembre, 2010
Estados Unidos de América

Impacts of rural land development on natural resources in the United States have been well documented and research on rural land development provides important inputs to land conservation policy and program development. Although numerous land-use studies have been completed for the western and eastern states, still lacking is a single study examining changes in population, housing, and land development in the two regions.

Modeling canopy conductance under contrasting seasonal conditions for a tropical savanna ecosystem of south central Mato Grosso, Brazil

Journal Articles & Books
Diciembre, 2016
Brasil

Temporal variations in land-atmosphere water vapor exchange are more pronounced in seasonal environments, especially grass-dominated savannas (known as campo sujo Cerrado) of the southern and eastern Amazon Basin. Recent work in campo sujo indicates that rates of canopy conductance (gc) were directly and indirectly affected by a variety of meteorological variables, which limited our understanding of how seasonal variation in meteorology affected rates of gc. Thus, our overall objective here is to determine how individual meteorological variables affect seasonal variations in gc.
