Shortly after releasing a report on its climate change strategy in July 2017, the Food and Agriculture Organization (FAO) of the United Nations presents a new report at COP23 - this time focusing on the organization's concrete work on climate change.

Internal climate migrants are rapidly becoming the human face of climate change. According to this new World Bank report, without urgent global and national climate action, Sub-Saharan Africa, South Asia and Latin America could see more than 140 million people move within their countries’ borders by 2050.

As water is the most disruptive element in the ongoing climate crisis, how land is managed plays a major role in taming this disruption. This publication shows that avoiding, reducing and reversing land degradation can have positive long-term gains in water security.

Ce document constitue les actes du Colloque de restitution du programme de recherche APPI « Une action publique éclatée ? » organisé en décembre 2014. L’objectif du projet, mené dans le cadre de l’ANR les Suds II, est de comprendre comment, dans des pays africains dépendants de l’aide, se construit et se met en oeuvre l’action publique. Il a mobilisé les concepts et méthodes issus de plusieurs courants d’analyse tels que les sciences politiques, la socio-anthropologie du développement et l’économie institutionnelle, avec un souci d’empirisme.

Lakes are integrator of environmental changes occurring at a regional to global scale and present a high variety of behaviors on a variety of time scale. Their crucial importance as water stocks and retaining given the significant environmental changes occurring worldwide at many anthropocentric levels has increased the necessity of monitoring all its morphodynamic characteristics i.e. water level, surface area and volume.

The multiple forms of land acquisitions show direct and indirect implications on water. The motive to utilize, control or grab water is devised through acquiring land. There are embedded water issues in almost all land acquisitions. Practical challenges are explored especially in keeping the balance of water securities. The paper is done with the objective of analyzing the water implications, balance, priority and extent of security given to users in lieu of water security indicators and then examined against the regulatory frameworks and responses.

Climate change is a major driver of land use with implications for the quality and quantity of water resources. We apply a novel integrated impact modelling framework (IIMF) to analyze climate change impacts until 2040 and stakeholder driven scenarios on water protection policies for sustainable management of land and water resources in Austria. The IIMF mainly consists of the sequentially linked bio-physical process model EPIC, the regional land use optimization model PASMA[grid], the quantitative precipitation/runoff TUWmodel, and the nutrient emission model MONERIS.

The construction of consistent time series of land use presents a key challenge when accounting for elective land use-based activities under the Kyoto Protocol (wetland drainage and rewetting (WDR), cropland management (CM) and grazing land management (GM)), in which current land use-driven greenhouse gas emissions are compared to a reference situation in 1990. This case study is the first to demonstrate the feasibility of using high-resolution land-use proxies from different datasets for Kyoto accounting in a data-rich case study region in Germany.

Participatory water governance has become highly influential around the world as a means for managing water resources. Scholars and practitioners advocate for the inclusion of previously marginalized communities in water resources management through the devolution of power, responsibility, and participation. Where community institutions are weak or missing, experts recommend strengthening or re-building them to enable inclusive decision-making over water resources.

City planners, urban innovators and researchers are increasingly working on ‘future city’ initiatives to investigate the physical, social and political aspects of harmonized urban living. Despite this, sustainability principles and the importance of urban groundwater are lacking in future city visions. Using London as a case study, the importance of groundwater for cities is highlighted and a range of future city interventions may impact on groundwater are reviewed.

Water scarcity is among the contemporary problems of our time across the globe. The problem is worsened by policy failures to enforce water governance and watershed conservation. Consequently, it has curtailed the capacity of watersheds to release hydrological services, water in particular. We carried out this study to explore approaches for watershed conservation and investigate water governance challenges in Pangani River Basin, Tanzania. We collected data by using structured questionnaires and meetings with different actors in the study area.

Municipalities worldwide are confronted with the need to take long-term decisions about ageing water infrastructure in the face of unpredictable future developments. Previous studies on long-term decision making have proposed solutions targeted at the domain of either politics or planning. This study combines insights from the domains of policy, politics, and planning by using the Multiple Streams Framework to explain what enables municipalities to take forward-looking investment decisions.
