Understanding the effects of land-cover alterations on ecosystem functioning has become a major challenge in ecological research during the last decade. This has stimulated a rapid growth in research investigating the links between land-cover change and biotic interactions, but to date no study has evaluated the progress towards achieving this scientific goal.
Contested institutions? Traditional leaders and land access and control in communal areas of Eastern Cape Province, South Africa
The South African government has endeavoured to strengthen property rights in communal areas and develop civil society institutions for community-led development and natural resource management. However, the effectiveness of this remains unclear as the emergence and operation of civil society institutions in these areas is potentially constrained by the persistence of traditional authorities. Focusing on the former Transkei region of Eastern Cape Province, three case study communities are used examine the extent to which local institutions overlap in issues of land access and control.
Carbon blinkers and policy blindness: The difficulties of ‘Growing Our Woodland in Wales’
The need for climate change mitigation has led to a recent upsurge in policies aimed to deliver re-afforestation across the globe, but with mixed successes observed depending upon the levels of private land ownership and ability of governments to engage land managers. This paper evaluates a new government-led scheme in Wales, which is intended to increase woodland cover from 14% to 20% by 2030 to offset the greenhouse gas emissions from agriculture.
Determinants of agricultural land abandonment in post-Soviet European Russia
The breakdown of socialism caused massive socio-economic and institutional changes that led to substantial agricultural land abandonment. The goal of our study was to identify the determinants of agricultural land abandonment in post-Soviet Russia during the first decade of transition from a state-controlled economy to a market-driven economy (1990–2000). We analyzed the determinants of agricultural land abandonment for approximately 150,550km² of land area in the provinces (oblasts) of Kaluga, Rjazan, Smolensk, Tula and Vladimir in European Russia.
impact of mediterranean land degradation on agricultural income: A short-term scenario
The present study estimates the potential costs of land degradation (LD) in agriculture at the national scale in Italy during 2000–2006 and provides a medium-term scenario for 2015 based on changes in climate conditions and human pressure. According to the user cost approach, a depletion factor (S) to agricultural income has been derived from the observed changes in a composite index of land sensitivity to degradation. Based on S figures, the investigated area has been classified into five risk categories from ‘negligible’ to ‘high’.
