We established the statistical relationships between seasonal weather variables and average annual wheat yield (Hard Red Spring and Durum wheat: Triticum spp.) for the period of 1979–2016 for 296 rural municipalities (RMs) throughout six soil zones comprising the arable agricultural zone of Saskatchewan, Canada. Controlling climate variables were identified through Pearson’s product moment correlation analysis and used in stepwise regression to predict wheat yields in each RM.

The growing demand for biofuel production increased agricultural activities in South Dakota, leading to the conversion of grassland to cropland. Although a few land change studies have been conducted in this area, they lacked spatial details and were based on the traditional bi-temporal change detection that may return incorrect rates of conversion. This study aimed to provide a more complete view of land conversion in South Dakota using a trajectory-based analysis that considers the entire satellite-based land cover/land use time series to improve change detection.

Over the past few decades, there has been increasing interest in recording landscape change. Monitoring programmes have been established to measure the scope, direction and rate of change, and assess the consequences of changes for multiple interests, such as biodiversity, cultural heritage and recreation. The results can provide feedback for multiple sectors and policy domains. Political interests may change over time, but long-term monitoring demands long-term funding. This requires that monitoring programmes remain relevant and cost-efficient.

Ecosystem services (ESs) are increasingly being used by many countries around the world as a framework for addressing the United Nations (UN) Sustainable Development Goals (SDGs). This review article of the usability of Libyan soil databases for ESs and SDGs is the first of its kind for North Africa.

In the high Andes, environmental and socio-economic drivers are transforming agriculture and presumably affecting the in situ conservation of potato (Solanum spp.). To monitor the use and conservation of intraspecific diversity, systematic and comparative studies across agricultural land-use systems are needed. We investigated the spatial-temporal dynamics of potato in two landscapes of Peru’s central Andes: A highland plateau (Huancavelica) compared to an eastern slope (Pasco).

Ce numéro de « Regards sur le foncier » est composé d’une revue bibliographique et des communications écrites par des jeunes chercheurs. Ces textes sont issus des journées d’études de juillet 2018 organisées par le Comité technique « Foncier & développement » dans le cadre du chantier de réflexion collective « Systèmes agraires et accès des jeunes à la terre ».

Since the early 2000s the Lao government has dramatically increased the number of large-scale land concessions issued for agribusinesses. While studies have documented the social and environmental impacts of land dispossession, the role of Vietnamese labour on these Vietnamese-owned rubber plantations has not previously been investigated. Taking a political ecology approach, we situate this study at the intersection between ‘land grabbing’ studies and work on ‘labour geographies’.

ABSTRACTED FROM EXECUTIVE SUMMARY: This research analyses the ways in which current changes in land tenure, agrarian and socio-economic systems are reshaping resource allocations and transfers within households in indigenous communities in Ratanakiri Province, Cambodia. While other gendered aspects of the transformations occurring in indigenous societies have received more attention in recent years, the changes occurring in the customary laws that determine land access, ownership and inheritance alongside gender, as well as generational lines, have not been explored.

WEBSITE INTRODUCTION: This report presents a synthesis of the main findings from case studies carried out in six countries in Africa (Ghana, Sierra Leone, United Republic of Tanzania and Zambia) and Asia (Laos and Philippines). The findings were disseminated and discussed in multistakeholder initiatives at regional and country level. The report illustrates how poor rural women and men are affected differently by agricultural investments, and demonstrates that they may not benefit equally from emerging opportunities.
