The Tarim Basis is a major source of windblown dust in China. Land management and use can greatly impact windblown dust, thus, models such as the Wind Erosion Prediction System (WEPS) are important for identifying management practices that reduce the emission of dust. The objective of this study was to test the performance of the WEPS erosion submodel (the Single-event Wind Erosion Evaluation Program (SWEEP)) under contrasting agricultural land use types in the Tarim Basin of northwest China.

In this study, main aim is to investigate the sustainable management according to the water and sediment yield of Kucukelmalı pond basin. Potential soil loss was calculated by using the USLE equation for the basin.

Bu çalışmada, Küçükelmalı Gölet Havzasının arazi kullanım planı toprak koruma önlemlerine göre hazırlanmıştır. Havzadaki potansiyel toprak kayıpları USLE eşitliği kullanılarak belirlenmiştir.

Part of the Himalayan biodiversity hotspot, Yunnan province in China is a highly diverse terrestrial region, particularly in the wide range of natural forest types. These forests are under considerable conversion pressure as land use intensifies with expanding human population and economic development. Conservation strategies based on the geographic patterns of botanical species richness, including the identification of meaningful floristic regions and priority areas for conservation, could improve the effectiveness of forest policy and management.

Sustaining freshwater systems in the face of rapid changes in land use continue to be a major challenge in lake watersheds. Lake Egirdir is a major freshwater lake in Turkey and is significant in supporting several ecosystem services of the region. The nutrient loading from both point and nonpoint sources has reduced the quality of the tributaries and the lake ecosystem. There is a need for comprehensive modeling of strategies to protect the lake and watershed ecosystems.

In 2002 the Danish Minister of Environment initiated a process to investigate the possibilities of establishing national parks in Denmark. For this purpose experts were mobilised to investigate the status and potentials of the areas in question. The national park process was extensive in scope and complex, and in theory such complexity is assumed to make it difficult for non-experts to understand all the relevant aspects of policy. This exclusion of non-experts may lead to scientification of politics.

Global trends in pollinator‐dependent crops have raised awareness of the need to support managed and wild bee populations to ensure sustainable crop production. Provision of sufficient forage resources is a key element for promoting bee populations within human impacted landscapes, particularly those in agricultural lands where demand for pollination service is high and land use and management practices have reduced available flowering resources.

Most anthropogenic activities impacted on water quality and quantity, and further impacted on ecosystem services (ESs) in watershed are related to land use and climate changes those may cause losses of ecosystem functions. Effective information regarding ESs and their optimal priority conservation planning responded to land use and climate changes provide useful support for diverse stakeholders in ESs planning, management and policies.

This article presents an investigation of relationships between organic farming and landscape composition in Denmark. Landscape composition was analysed in terms of density of uncultivated landscape elements (I), number of land uses per hectare (II), diversity of land use (III) and mean field size (IV). Two analytical approaches were used. The first was based on an examination of the national agricultural registers for 1998, 2001 and 2004.

An average of 16 years' data at sites in the upper Taireri River catchment was used to determine if water quality had changed commensurate with an increase in the irrigated area and land-use change. To help remediate perceived gaps in the nutrient modelling software Overseer®, data was also collected from a low-intensity border dyke and high-intensity spray-irrigated property. Filterable reactive phosphorus concentrations increased over time and were attributed to the irrigation of poor anion storage capacity (ASC) soils and irrigation-return flows.
