Mining And Its Implications On Food Security In Amansie West And South Districts, Ghana.

Semi-arid rangelands in Sub-Saharan Africa (SSA) are an important source of food security and nutrition but are under increased anthropogenic pressure by a growing population. These rangelands are characterized by nutrient poor soils and distinct wet and dry season(s).

Abstract: Flood-attributed damages to infrastructure and public safety are expected to escalate in the future due to climate change, land use change, and associated hydrologic changes. In recent years, the reliability of flood forecasts has increased due to the availability of meteorological and hydrological data and advancements in flood prediction science.

Increasing flood damage has led to a rising importance of land use in flood risk management policies, commonly referred to as the spatial turn in flood risk management. This includes policies aiming at making space for rivers, which, in practice, lead to an increasing demand for land.

Gross primary productivity (GPP) is the most basic variable in a carbon cycle study that determines the carbon that enters the ecosystem. The remote sensing-based light use efficiency (LUE) model is one of the primary tools that is currently used to estimate the GPP at the regional scale.

There are many new land use and land cover (LULC) products emerging yet there is still a lack of in situ data for training, validation, and change detection purposes. The LUCAS (Land Use Cover Area frame Sample) survey is one of the few authoritative in situ field campaigns, which takes place every three years in European Union member countries.

We measure the eco-efficiency (EE) of agricultural production in regard to soil erosion and decompose it into technical efficiency (TE) and soil conservation efficiency (SCE). 

State-of-the-art forest management requires an adequate opening-up in terms of forest roads. In addition to the increased efficiency of harvesting operations, a higher road density may trigger other positive and negative side-effects. Austria has a long tradition of forestry, and also of monitoring the economic performance of forest enterprises by means of forest accountancy data networks.
