On-Farm Information: A Valuable Tool For The Sustainable Management Of Mountain Pastures In Protected Natural Areas, N. Mandaluniz, A. Bernués, A. Igarzabal, I. J. L. Riedel, R. Ruiz, A. Sanz, I. Casasús, L. M. Oregui
On-Farm Information: A Valuable Tool For The Sustainable Management Of Mountain Pastures In Protected Natural Areas, N. Mandaluniz, A. Bernués, A. Igarzabal, I. J. L. Riedel, R. Ruiz, A. Sanz, I. Casasús, L. M. Oregui

Mountain pastures have traditionally been maintained by livestock. The analysis of data concerning farms' characteristics, productive-reproductive management and land use of commercial farms can constitute a real approach to study these systems and the changes that are occurring. This information is necessary to develop new utilisation guidelines, making compatible livestock production and conservation of natural resources. This paper describes a methodological framework to study the issues described above through some examples taken out from a wider research project (Mandaluniz et al., 2003).
Do Species And Functional Diversity Indices Reflect Changes In Grazing Regimes And Climatic Conditions In Northeastern Spain?, F. De Bello, J. Leps, M. T. Sebastià

Understanding the mechanisms that maintain biodiversity in various ecosystems enables the development of management practices that prevent degradation (Canals & Sebastia, 2000). Each diversity index reflects some compositional properties and could be influenced differently by stress and disturbance factors (Magurran, 2004). In this study, we aim to reveal 1) which management practices and environmental factors affect biodiversity in rangelands of northeastern Spain and 2) the relationship between species diversity and functional diversity (SD and FD).
Net Ecosystem Productivity Of A Grassland In Comparison With An Arable And A Forest Ecosystem, Phillip A. Davis, K. Black, J. Clifton-Brown, G. Lanigan, J. Burke, A. Fortune, M. B. Jones, B. Osborne
Net Ecosystem Productivity Of A Grassland In Comparison With An Arable And A Forest Ecosystem, Phillip A. Davis, K. Black, J. Clifton-Brown, G. Lanigan, J. Burke, A. Fortune, M. B. Jones, B. Osborne

Grassland, arable farming and forests are the major land use categories in Ireland and it is, therefore, important to know the carbon-source/sink strengths of these land use types. Forest ecosystems are also an important and fast growing land use category in Ireland. Here we present a comparison of the net ecosystem productivity (NEP) of these three land use categories (grass land, arable and forest) from three sites.
The Suitability For Organic Cattle Beef Production Of Mixed Farming Systems In The Highlands Of North East Portugal, J. M. Pires, M. Rodrigues, F. Sousa, A. Bernardo, J. C. Pires, J. Cabanas, H. Resendes, M. J. Ferreira, M. I. Silva, N. Moreira

The EC Reg. 1804/99 takes account of animal production in organic farming. However, these specifications may limit implementation and expansion of organic animal production, due to environmental and system constraints. Mixed farming, as defined by Spedding (1988) and Grigg (1996), is commonly practiced in the NE highlands of Portugal. Two farms were studied in this region in order to evaluate their suitability for organic cattle beef production, taking account of the technical specifications of the EC regulation.
Implications Of Land Use Changes On The Yields In Dry Matter, Energy And Protein Of Range And Crop Fields In Zamfara Reserve, Northwestern Nigeria, B. S. Malami, P. H. Y. Hiernaux, H. M. Tukur, B. Rischkowsky

The Zamfara reserve is a 235,500 ha grazing land within the Sudan savannah zone (12º 10' - 13º 05 N; 6º 30' - 7º15' E) of north western Nigeria. Rainfall varies from 500mm in the north to 800mm in the south of the reserve, and is restricted within the months of May - September. The reserve is an important grazing site for the herds of sedentary, transhumant and agro pastoralists. Population growth within the farming communities in the reserve has led to the conversion of more grazing land to croplands. This work was carried out to evaluate the quantity and …

Effects Of Landscape Structure On Plants Species Richness In Small Grassland Remnants In Two Different Landscapes, S. A. O. Cousins, O. Eriksson
Effects Of Landscape Structure On Plants Species Richness In Small Grassland Remnants In Two Different Landscapes, S. A. O. Cousins, O. Eriksson
IGC Proceedings (1997-2023)
There is an increasing interest in using the landscape as the operational scale in many ecological studies. Current species richness in the landscape may be explained by past land use, and habitats may harbour species favoured by an environment that no longer exists. In this study we have included both a landscape scale and a temporal scale. The objective was to explain species pattern and the effect of isolation, habitat size and surrounding land use, and past land use change, on small grassland remnants in rural landscapes.
The Future Of Pandemics: Land Use Controls As Means Of Preventing Zoonotic Disease, Bailey Andree
The Future Of Pandemics: Land Use Controls As Means Of Preventing Zoonotic Disease, Bailey Andree
Pace International Law Review
Zoonotic diseases are increasing in frequency as climate change worsens around the world, with the recent COVID-19 pandemic highlighting the inadequate mechanisms in place to counteract disease spread. This article reviews various zoonotic diseases and their patterns of spread, highlighting land use change as the key driver of disease to demonstrate the need for legal intervention. International land use law is a little-developed subsect of environmental law that holds the key to combating this disease spread, and this article proposes solutions through this legal lens. Land use techniques which may be used to combat disease spread include conservation laws, setback …
Paleolimnological Data Synthesis To Assess Long-Term Ecological Change In Vermont Lakes, Ismar Biberovic
Paleolimnological Data Synthesis To Assess Long-Term Ecological Change In Vermont Lakes, Ismar Biberovic
Graduate College Dissertations and Theses
Lakes are excellent early indicators of environmental change on a landscape scale. Due to their connectedness in the landscape, any alteration of land-cover extends beyond a single watershed and can only be amplified by the effects of climate change. These processes can reflect differently across lakes of various characteristics, however, combined, they can leave a lasting impact on biogeochemical processes of a lake, resulting in profound effects on biological communities residing in it. Lake sediments are terrific archives that integrate and preserve this evidence, which then allows us to investigate the extent to which a lake has changed given its …
