    Vietnam

    Studies of land property rights usually focus on tenure security and transfer rights. Rights to determine how to use the land are regularly ignored. However, user rights are often limited. Relying on a unique Vietnamese panel data set at both household and plot levels, we show that crop choice restrictions are widespread and prevent crop diversification. Restrictions do not decrease household income, but restricted households work harder, and there are indications that they are supplied with higher quality inputs.

    Laos

    In the early 1990s, the Lao government launched a nationwide Land Use Planning and Land Allocation programme in a bid to foster socio-economic development while protecting the environment. However, the programme has long been perceived as having negative impacts on rural livelihoods. A central criticism was that limited local participation results in unsustainable land use plans; consequently, the government introduced significant changes into the process to enhance participation.

    The current approach to peacebuilding by the international community is to focus on the priorities thought to be important to recovery, but this occurs in a largely non-integrated way. With these different endeavors largely isolated from each other in planning, analysis, implementation, and measures for success, little is known about how they interact and whether or not the aggregate effect contributes to, or detracts from durable peace. This is especially important for priorities which in some way interact with each other on the ground among a recipient population.

    Mexico

    In the Mexican coasts, as in many tropical and subtropical coastal areas, shrimp culture grew exponentially over the last three decades. This process has produced an intense debate on the economic benefits but also about the extent and intensity of the impact of this activity on the coastal ecosystems, particularly the effects of pond construction on mangrove areas and other coastal wetlands.

    India

    India's forest policy regime enacted so far had alienated the common users of their property rights in the name of forest and wildlife conservation. However, poor conservation outcomes have forced planners to reconsider the role of the forest community in resource use and conservation. Presence of a deep-rooted economic, social, cultural and ethical difference between members of Forest Protection Committee (FPC) constrains group behaviour and their capacity to modify regulations governing resource use.

    Assessing the potential impact of future land-cover changes on habitat quality requires projections with a fine spatial and thematic resolution. The former is usually addressed by downscaling methods, often at the expense of the latter. We present a new, rule-based method to downscale land-use change scenarios to the landscape level while keeping a large number of land-cover classes (CORINE level 3). The method relies on the interpretation of European scenario storylines, the observation of past land-use changes, high-resolution regional data and expert knowledge.

    Italy

    In this paper is presented a methodological approach which integrates statistic modelling and 2-D cellular automata (CA) in order to describe tree species shifts responding to the climate changes foreseen for Italy in the 21st century. Five Italian tree species populations of Abies alba, Pinus sylvestris, Fagus sylvatica, Acer campestris and Quercus suber and their actual potential distributions (PDs) – represented by Importance Value (IV), have been considered.

    Freshwater lakes are known to release carbon dioxide (CO₂) and methane (CH₄) to the atmosphere; however, the importance of lakes in global nitrous oxide (N₂O) budgets is not yet known. Further, despite the abundance of small lakes on the landscape, neither emissions of these gases nor their drivers are well described.

    Riparian vegetation plays a crucial role on affecting the floodplain hydraulic roughness, which in turn significantly influences the dynamics of flood waves. This paper explores the potential accuracies of retrieving vegetation hydrodynamic parameters through satellite multispectral data.
