spatio-temporal responses of the carbon cycle to climate and land use/land cover changes between 1981–2000 in China

Journal Articles & Books
Décembre, 2013
Chine

This paper represents the first national effort of its kind to systematically investigate the impact of changes in climate and land use and land cover (LULC) on the carbon cycle with high-resolution dynamic LULC data at the decadal scale (1990s and 2000s).

Grazing intensity affected spatial patterns of vegetation and soil fertility in a desert steppe

Journal Articles & Books

Chine

Spatial heterogeneities of vegetation and soil can strongly affect ecological functions of ecosystems, particularly for arid and semi-arid ecosystems where vegetation has a patchy distribution and livestock grazing is one of the major land use types. However, little is known about the impact of grazing on spatial patterns of vegetation and soil, even though grazing has variously been shown to create, maintain or destroy those patterns.

Spatial properties of large agricultural landholdings of Estonia

Estonie
Lettonie

The fragmentation of landholdings is considered as disturbing factor for agriculture. The aim of this article is to evaluate the extent of land fragmentation of the large landholdings in Estonia. The Januszewski and Schmook indexes were calculated for that purpose. The detailed survey of three agricultural landholdings was conducted in order to assess the possibilities to reduce the land fragmentation and improve their land use conditions. Results showed that Estonian agricultural producers’ landholdings are considerably fragmented.

Potential possibilities for the use of land in Latvia

Conference Papers & Reports
Décembre, 2007
Lettonie

The ongoing processes in agriculture, and the national economy in general, as well as continuous targeted reconstruction of the European Union Common Agricultural and Rural Development Policy, and other processes of globalisation and international integration, steadily and directly resound to Latvia, and create new objectives related to the use of land. The agreement on rural development adopted during the European Union Salzburg Conference has also established or determined new functions for the use of land.

Simulated dynamics of carbon stocks driven by changes in land use, management and climate in a tropical moist ecosystem of Ghana

Ghana
Afrique

Sub-Saharan Africa is large and diverse with regions of food insecurity and high vulnerability to climate change. This project quantifies carbon stocks and fluxes in the humid forest zone of Ghana, as a part of an assessment in West Africa. The General Ensemble biogeochemical Modeling System (GEMS) was used to simulate the responses of natural and managed systems to projected scenarios of changes in climate, land use and cover, and nitrogen fertilization in the Assin district of Ghana.

Mars, 2011

A „Gazdálkodás” 2010. évi 2. számában vitacikkem jelent meg „A földbirtok-politikaválaszt igénylő kérdései” címen. Ezzel az volt a célom, hogy a témakörrel kapcsolatban felvessek kérdéseket, leírjak megállapításokat, és ezzel egy olyan vitát generáljak, ami fórumot ad a tudományos közélet szereplőinek a megszólalásra, a vélemények ütköztetésére, egymás nézeteinek jobb megértésére, a politika számára javaslatok megfogalmazására.

Changes over three decades in the floristic composition of fertile permanent grasslands in the Swiss Alps

Journal Articles & Books
Décembre, 2008

This study investigates how the floristic composition and species richness of fertile grasslands in the Swiss Alps has changed over the last three decades. A total of 259 phytosociological relevés in four regions were resurveyed after periods of between 17 and 29 years. Analysis of the data revealed that floristic composition of the grasslands changed significantly during the study period, although the factor 'time' explained only a small proportion of the total variation (2.0-4.1%).

Drainage development: Driving forces, conducive conditions and development trajectories

Journal Articles & Books
Décembre, 2011

The core of this paper consists of an analysis of the forces and conducive conditions which historically have driven the drainage development of agricultural land. Such forces and conditions are recognised at three levels of discretion: (i) the generic level (ii) the government level (iii) the on‐farm level. The drainage development for salinity control of irrigated land in the (semi) arid zone is treated as a special case of drainage development driven by its own specific forces and considerations.

Tracking environmental dynamics and agricultural intensification in southern Mali

Mali

The Office de la Haute Vallée du Fleuve Niger (OHVN) zone in southern Mali is a small but important agricultural production region. Against a background of environmental degradation including decades of declining rainfall, soil erosion, and human pressure on forest resources, numerous farming communities stand out through the use of improved soil and water management practices that have improved agricultural and environmental conditions. Field surveys conducted in 1998-2001 indicated that environmental and agricultural conditions have improved in the past decade.

Development projects bring tremendous changes in patterns of use of land, water, and other natural resources which leads to a range of resettlement effects. This process of economic and social dislocation most often exacerbates existing gender disparities and inequalities in affected areas. When gender differences are overlooked in project planning phase, projects are unlikely to respond to women’s need and may even have negative consequences.
