Adoption of Conservation Agriculture Technologies by Smallholder Farmers in the semiarid region of Tunisia: Resource constraints and partial adoption

Journal Articles & Books
april, 2019
Northern Africa
Tunisia

Tunisia, like many other countries, suffers from land degradation. Conservation agriculture is among the proper solutions to overcome this issue. The objective of our investigation is to determine the factors that influence the adoption of CA in Siliana, one of Tunisia’s most affected regions by erosion. A field survey was conducted to collect adoption data used for descriptive analysis, and for the estimation of a choice model (Logit).

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
april, 2019
Monaco
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
april, 2019
Malaysia

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
april, 2019
United States of America

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.

Données d’observations de la terre et outils cartographiques libres à la caractérisation de la dynamique foncière face à l’accaparement des terres à grande échelle au sud-ouest Cameroun.

Peer-reviewed publication

Cameroon

Situé en plein cœur de la forêt équatoriale dans le bassin du Congo, la région du Sud-ouest est sans doute l’une des plus riches du Cameroun. Elle comporte une biodiversité des plus diversifiées avec une importance significative des espèces endogènes ainsi que des espèces commerciales. Les conditions pédologiques, hydrographiques et orographiques sont favorables à l’agriculture, ce qui a amené les allemands dès leurs arrivées au Cameroun à s’y implanter.

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

Peer-reviewed publication
april, 2019
Africa

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
april, 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 Global Symposium on Soil Erosion (GSER19) represented a critical step towards the implementation of the Voluntary Guidelines for Sustainable Soil Management (VGSSM) in terms of minimizing the risk of soil erosion. GSER 19 identified effective and ineffective Sustainable Soil Management (SSM) practices, techniques, instruments and mechanisms which shed light on where the gaps and challenges are in terms of science, technology and legislation.

Modelling Development of Riparian Ranchlands Using Ecosystem Services at the Aravaipa Watershed, SE Arizona

Peer-reviewed publication
april, 2019
Mexico

This paper describes how subdivision and development of rangelands within a remote and celebrated semi-arid watershed near the US–Mexico border might affect multiple ecohydrological services provided, such as recharge of the aquifer, water and sediment yield, water quality, flow rates and downstream cultural and natural resources. Specifically, we apply an uncalibrated watershed model and land-change forecasting scenario to consider the potential effects of converting rangelands to housing developments and document potential changes in hydrological ecosystem services.
