    Moldavia, Europa oriental

    Agriculture in the Republic of Moldova has been facing a number of challenges in recent decades, caused by both traditional agricultural practics and effects of climate change. Growing environmental issues, like soil degradation, water pollution, reduced biodiversity, require re-evaluating current agricultural methods.

    An attempt was made to assess the land condition while taking into consideration environmental and socio-economical parameters that could be drivers of ongoing land degradation processes. Many of these variables have spatial and temporal characteristics and can therefore be monitored through GIS-based tools thus contributing valuable information for assessing land degradation risk.

    In recent decades, multi-spectral and hyper-spectral remotely sensed imageries with high and modern spatial resolutions at sufficient time-series interval have been developed. This allows for detecting crop types and its distribution over large areas and at short time intervals. Among the advantages of remote sensing technologies are its cost effective evaluation over extensive areas and the ability to provide reliable information on land surface conditions. This is useful also for areas with sporadic information on the spatial extent of croplands effected by for instance water scarcity.

    This document aims to contribute to the empirical development of effective approaches for the assessment of rangeland governance at local levels, and provide insights about major governance drivers through the quantitative assessment of their effects. Our focus is an application of the Bayesian Belief Network (BBN) methodology to assess key variables that affect the probability of good rangeland governance under contrasting contexts of land tenure in Southern Tunisia.

    Rangelands are recognized for their importance and value in providing society with valuable products and ecosystem services. In such ecosystems, effective management is needed for sustainable plant growth and survival in a context characterized by rainfall unreliability, poor soil nutrient status and high uncontrolled grazing. Therefore, cost-effective techniques/tools for slowing down and eventually reversing this degradation are needed. This paper promotes identifying and combining various tools for degraded arid ecosystems as strategies aimed for rangeland restoration/ rehabilitation.

    Project goal is to reduce food insecurity and improve livelihoods of poor people living in African
    drylands by restoring degraded land
    and returning it to effective and sustainable
    tree, crop and livestock production, thereby
    increasing land profitability as well as landscape
    and livelihood resilience.
