In the face of increasing socio-economic and climatic pressures in growing cities, it is rational for managers to consider multiple approaches for securing water availability. One often disregarded option is the promotion of reforestation in source regions supplying important quantities of atmospheric moisture transported over long distances through aerial rivers, affecting water resources of a city via precipitation and runoff (‘smart reforestation’). Here we present a case demonstrating smart reforestation’s potential as a water management option.

Spatial distribution and uncertainties of nitrogen budgets for agriculture in the Tagus river basin in Portugal – Implications for effectiveness of mitigation measures

Peer-reviewed publication
Abril, 2019
Mónaco
Portugal

The present study describes a methodology to quantify the gross soil nitrogen balance (SNB) for agricultural land use in the Tagus Nitrate Vulnerable Zone (TVZ) between 1989 and 2016, including effects of implementation of the EC Nitrates Directive (ND, 91/676/EEC) since 2004. The study uses decadal information from National Agricultural Census at parish level and is supported by a Geographical Information System (GIS). The average SNB of the TVZ decreased significantly (p 

Urban-rural divides in preferences for wetland conservation in Malaysia

Peer-reviewed publication
Abril, 2019
Malasia

We examined the preferences for wetland conservation among urban and rural dwellers in Malaysia. A choice experiment using face-to-face interviews with urban and rural households was employed. Wetland conservation alternatives were described in terms of environmental protection zones, biodiversity protection, recreational services and flood. Each alternative was connected to a cost for the household, which was a reduction in subsidies for daily goods. Using a latent class model, we identified three groups with distinctly different preferences.

Urban planning as an enabler of urban health: Challenges and good practice in England following the 2012 planning and public health reforms

Peer-reviewed publication
Abril, 2019
Estados Unidos de América

This article synthesises the challenges faced by the English (urban) spatial planning system to become an enabler of urban health and explores some keys features of the evidence base, policy tools and policy implementation issues that urban planners need to be aware of to become health enablers. It draws on good practice identified in an Economic and Social Research Council (ESRC) seminar series involving over 500 academic researchers and practitioners between 2015 and 2017. A number of key recommendations emerged out of the project.

Climate, Land Use Change and Local Adaptation Strategies in Ecological Areas. Case of Miwaleni River Valley

Peer-reviewed publication
Abril, 2019
África

Climate change issues are contemporary global phenomena which affect the largest part of the world in different ways. This paper explores how local communities living in sensitive ecological areas, particularly in river valleys, respond to and adapt to climate change. By employing a qualitative research approach, findings have indicated that heavy rainfall and prolonged droughts coupled with population increase have led to land use changes and loss of biodiversity in the river valley.

The role of institutional actors and their interactions in the land use policy making process in Ethiopia

Journal Articles & Books
Abril, 2019

This study investigates the role of the different institutional actors involved in the development and implementation of land use policies in the Ethiopian Rift Valley. The work is based on interviews with key informants from different administrative levels and these results are compared to the relevant policy documents. While the constitution prescribes a participatory policy development process, our results show that in reality policies are made at the highest level and implemented in a top-down approach from the higher to the lower administrative levels.

The Impact of Rapid Urbanization and Public Housing Development on Urban Form and Density in Addis Ababa, Ethiopia

Peer-reviewed publication
Abril, 2019
África

Urban development is occurring in many Sub-Saharan Africa cities and rapid urbanization is underway in the East African city of Addis Ababa, Ethiopia. In an effort to address urban poverty and increase homeownership opportunities for low and middle-income residents, the City Administration of Addis Ababa initiated a large-scale housing development project in 2005. The project has resulted in the completion of 175,000 units within the city with 132,000 more under construction.

Future governance options for large-scale land acquisition in Cambodia: Impacts on tree cover and tiger landscapes

Journal Articles & Books
Abril, 2019
Cambodia

This paper investigates how large-scale land acquisitions (LSLAs) can be governed to avoid underuse and thereby spare room for other land claims, specifically nature conservation. LSLA underuse occurs when land in LSLAs is not converted to its intended use. Taking Cambodia as a case, we map converted and unconverted areas within LSLAs using remote sensing. We develop three scenarios of alternative LSLA policies until 2040, and use a land system change model to evaluate how governing the underuse of LSLAs affects overall land use.

Adoption of improved amaranth varieties and good agricultural practices in East Africa

Peer-reviewed publication
Marzo, 2019
Kenya
Tanzania

This study quantifies the adoption of improved amaranth varieties in Kenya and Tanzania, and the extent to which these result from international vegetable breeding research conducted by the World Vegetable Center (WorldVeg) and partners. The study used expert elicitation and a questionnaire survey among vegetable seed producers. Nine expert panels were conducted involving 123 local experts. The results show that improved amaranth varieties were planted on 51% of the planted area in Kenya and 70% in Tanzania.

Survey methodologies of urban land uses: An oddment of the past, or a gap in contemporary planning theory?

Peer-reviewed publication
Marzo, 2019
Global

The primary objective of this article is to review the evolution of urban land-use survey methodologies during the last century, with a special focus on the methodologies concerning field surveys that are conducted for urban planning purposes. Our review reveals, on the one hand, that there has been a steep decrease of interest in the further development of these methodologies over the last 50 years, and, on the other, that they have been seriously trivialized, as shown by the simplistic and empirical approach to land-use survey methodology in contemporary textbooks.
