How effective are broad-scale nutrient mass balances for determining the sustainability of lot-feed manure application

Journal Articles & Books
Diciembre, 2007

Nutrient mass balances have been used to assess a variety of land resource scenarios, at various scales. They are widely used as a simple basis for policy, planning, and regulatory decisions but it is not clear how accurately they reflect reality. This study provides a critique of broad-scale nutrient mass balances, with particular application to the fertiliser use of beef lot-feeding manure in Queensland.

Adoption of maize production technologies in Eastern Tanzania

Journal Articles & Books
Diciembre, 1998
Tanzania

This study of the adoption of maize production technologies in Eastern Tanzania forms part of a larger study to evaluate the impact of maize research and extension throughout Tanzania over the past 20 years. Using a structured questionnaire, researchers and extension officers interviewed farmers in June-November 1995. Survey data were classified by agroecological zone (the lowlands and the intermediate zone).

Efficiency indicators of farmlands use

Policy Papers & Briefs
Diciembre, 2012
Belarús

The review of efficiency indicators of farmlands use was given. Their classification was analyzed and positive and negative sides of their various kinds were considered. Efficiency dependence of farmland use on value of specialization factor was investigated. Offers on perfection of system of the indicators characterizing rationality and efficiency of application of farmlands were made and also new approaches to an estimation of economic efficiency of their use were offered. The research was realized in the conditions of the Republic of Belarus.

GIS-integrated fuzzy rule-based inference system for land suitability evaluation in agricultural watersheds

Journal Articles & Books
Diciembre, 2009
India

Land suitability evaluation in water scarce agricultural watersheds consists of assessment of land potential for various crops as well as surface water potential to identify the scope for supplementary irrigation. A large amount of information related to the crop land suitability can be conveyed through linguistic terms. Capability of fuzzy sets in modeling involving uncertainty and vagueness is made use of in fuzzy rule-based systems, where various decision making criteria in linguistic terms are expressed as fuzzy rules.

Substantiation of the sizes of the central farmsteads of the agricultural organizations

Policy Papers & Briefs
Diciembre, 2012
Belarús

In course of the research there was resulted the developed model of optimization of the sizes of land tenure of the agricultural enterprises. The research was realized in the conditions of the Republic of Belarus. As a result of realized research the optimum sizes of land tenure of the agricultural organizations with combinational organizational-industrial structure for average conditions of republic were established.

Historical legacy of the old-growth pine forest in Dividalen, northern Scandes

Journal Articles & Books
Diciembre, 2012
Suecia

The Dividalen (Sami: Dieváidvuovdi) valley in Troms county, North Norway, is well known for its old-growth pine forest, a biodiversity hotspot for dead wood-inhabiting fungi and lichens. The majority of the valley is protected within the Upper Dividalen Landscape Conservation Area and National Park. A general conception is that until the mid-nineteenth century when agriculture and forestry entered the valley, the landscape was entirely untouched by man and only used as a pathway for Sami and their reindeer herds on their annual migrations between Sweden and the Norwegian coast.

role of policies in land use/cover change since the 1970s in ecologically fragile karst areas of Southwest China: A case study on the Maotiaohe watershed

Journal Articles & Books
Diciembre, 2011
China

Study of land use/cover change and its driving forces is one of the most significant fields in global environmental change research. Karst land is a type of important and unique terrain on the Earth's surface because of its extensive distribution, impressive landforms, and high ecological fragility. Recently, more and more researchers have realized that irrational land use practices are leading to a series of alarming environmental issues including rocky desertification in karst areas.

Spatial Distribution and Temporal Change of Carbon Storage in Timber Biomass of Two Different Forest Management Units

Journal Articles & Books
Diciembre, 2007

Forests make up large ecosystems and can play an important role in mitigating the emissions of CO₂, the most important greenhouse gas. However, they are sources of atmospheric carbon when they are disturbed by human or natural causes. Storage of carbon through expansion and adaptive management of forest ecosystems can assist in reducing carbon concentrations in atmosphere.

impacts of shrimp farming on land use, employment and migration in Tumbes, northern Peru

Journal Articles & Books
Diciembre, 2013
Perú

Export-oriented shrimp aquaculture appeared in the coastal landscape of Peru in the late 1970s. Its rapid development has entailed both positive and negative environmental and socioeconomic impacts across the newly emerging shrimp farming territory of the Tumbes river delta. Here we combine ground surveys and interviews with remote sensing analysis of the transformed environment in order to characterize and quantify the nature, origin and scale of the environmental and social impacts caused by the intrusion of aquaculture.

Planning as trigger for land use changes

Conference Papers & Reports
Diciembre, 2015
Polonia
Letonia

In Poland significant changes in landscape intensified after the political transformation in late 1980’s. One of the signs of the changes are more transformations of agricultural land into developed land (industry, housing, services). At the same time, abandoned land started overgrowing with trees and brushwood. These are a result of changes in living and housing conditions, technical progress and changes in legislation. Local spatial plan is a planning act that defines the designation of the land in Poland.

Understanding Family Forest Land Future Ownership and Use: Exploring Conservation Bequest Motivations

Journal Articles & Books
Diciembre, 2016
Estados Unidos de América

Due to an aging landowner population, there will be an unprecedented ownership shift in land-based assets in the USA. Approximately 2.7 million family forest owners (FFOs) in the USA over the age of 55 years old, reflecting 80 % of all FFO-owned land, will be deciding the future ownership and use of their land, having significant implications for the landscapes and public benefits these forests provide. Little is known about how FFOs plan for the future ownership and use of their land.
