Fertilization is one of the most important factors to improve plant characteristics and nutrient uptake. Biological N2 Fixation (BNF) is a process of great importance in crop production systems, to enhance sustainability and prevent land degradation in modern agriculture. The impact of the biofertilizer (NPKB) produced from PK rock biofertilizer mixed with earthworm compound enriched in N by free living diazotrophic bacteria and of the bioprotector (NPKP) with chitosan from Cunninghamella elegans were investigated in a field experiment with melon.

Understanding vegetation dynamics provides information on changes in land cover that can directly be related to regional changes in the climate system. In data-sparse regions, i.e. northwest Morocco studies are limited by the availability of comprehensive information on precipitation.

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.

China has a long history of deforestation and environmental degradation. Because China is also lacking biological reserves, off-reserve conservation is a major contributor to its conservation efforts. Off-reserve conservation in China is primarily being achieved within afforestation and low-intensity agriculture. We compare ant diversity of three habitats: Natural Forest, Disturbed Forest and Plantation, to assess the conservation potential of these multiple land uses.

Human activities have exerted a powerful influence on the biogeochemical cycles of nitrogen (N) and carbon (C) and drive changes that can be a challenge to predict given the influence of multiple environmental stressors. This study focused on understanding how land management and climate change have together influenced terrestrial N storage and watershed inorganic N export across boreal and sub‐arctic landscapes in northern Sweden.

This review assesses existing data, models, and other knowledge-based methods for valuing the effects of sustainable land management including the cost of land degradation on a global scale. The overall development goal of sustainable human well-being should be to obtain social, ecologic, and economic viability, not merely growth of the market economy. Therefore new and more integrated methods to value sustainable development are needed. There is a huge amount of data and methods currently available to model and analyze land management practices.

Climate change and land use management practices are major drivers of biodiversity in terrestrial ecosystems. To understand and predict resulting changes in community structures, individual-based and spatially explicit population models are a useful tool but require detailed data sets for each species. More generic approaches are thus needed. Here we present a trait-based functional type approach to model savanna birds. The aim of our model is to explore the response of different bird functional types to modifications in habitat structure.

The carbon budget that was derived from forest land use has been extensively explored in most regions/countries of the Northern Hemisphere but is poorly documented in Central Asia. In this study, we proposed a localized bookkeeping model and estimated the sources and sinks of carbon from forest land use and managements between 1961 and 2010 in two arid regions of Central Asia, e.g., Kazakhstan and Xinjiang, China. The results indicate that the forest land use in these two regions acted as a carbon sink, with a total carbon sequestration of 43.27Tg and 20.74Tg respectively.

AIM: Global environmental changes challenge traditional conservation approaches based on the selection of static protected areas due to their limited ability to deal with the dynamic nature of driving forces relevant to biodiversity. The Natura 2000 network (N2000) constitutes a major milestone in biodiversity conservation in Europe, but the degree to which this static network will be able to reach its long‐term conservation objectives raises concern.

Many boreal waters are currently becoming browner with effects on biodiversity, fish production, biogeochemical processes and drinking water quality. The question arises whether and at which speed this browning will continue under future climate change. To answer the question we predicted the absorbance (a₄₂₀) in 6347 lakes and streams of the boreal region under future climate change. For the prediction we modified a numerical model for a₄₂₀ spatial variation which we tested on a temporal scale by simulating a₄₂₀ inter-annual variation in 48 out of the 6347 Swedish waters.

Spanish mountains have been affected by the expansion of shrubs and forests since the mid‐20th century. This secondary succession in vegetation has some positive effects, but also drawbacks, such as an increase in fire risk, loss of diversity in land use, a reduction in landscape and cultural value, less water available in river channels and reservoirs, constraints on livestock farming, a reduced number of local species and loss of biodiversity.
