Article
Full-text available
Whilst current policies recognize the impacts that changes in climates and markets have imposed on the Italian food system, less attention is given to the development of systematic approaches to identify alternative cropping systems across Italy and the European continent. In this article, a novel evidence-based crop shortlisting method was develop...
Article
Full-text available
Variations in soil structural and physiochemical properties can impact earth system models related to climate change. However, in most of the countries including Malaysia, soil data are available as low resolution and semi-detailed soil series maps, which hinder their applicability. Therefore, the objective of this study was to develop a framework...

An evidence base was developed to facilitate adoption of hemp (Cannabis sativa L.) in tropical environments [1]. Agro-ecological requirements data of hemp were acquired from international databases and was contrasted against local climate and soil conditions using an augmented species ecological niche modelling. The outputs were then used to map th...

While China has transformed its economy over recent decades, challenges such as climate change and land degradation have continued to impact its agriculture. These effects along with changes in diets and growing food imports will force China to look for alternative cropping options. Despite the broad potential of Bambara groundnut (Vigna subterrane...
Article
Hemp (Cannabis sativa L.) is a multipurpose industrial crop which is mainly cultivated in temperate regions. With its high potential for economic returns for its seeds and fiber, there is growing interest in cultivating hemp in many territories including Malaysia and other Asian countries, where its cultivation is currently illegal. To date, no com...

Article
Digital agriculture is driven by the interrelated needs to increase crop production, develop sustainable food systems and cope with the global change. Databases exist for several major crops but a barrier to increasing agrobiodiversity is the lack, and dispersed nature, of information for variously termed minor, orphan or underutilised crops. In th...

Assessment of land capability for a crop requires the bringing together of data on soils, climates and crop requirements. In Malaysia, the main method to identify suitable species for agriculture is soil-crop suitability classification based on a range of soil properties that can impose limits on crop growth. This method has been used widely by gov...

Project
https://landsupport.eu The objective of LANDSUPPORT is the construction of a web-based smart geoSpatial Decision Support System (S-DSS), which shall provide a powerful set of tools devoted to (i) support sustainable agriculture/forestry, (ii) evaluate trade-off between land uses including spatial planning) and (iii) contribute to implementation, impact and delivery of about 20 European land policies and also selected 2030 UN Sustainable Development Goals including climate change resilience goals and the key SDG 15.3 “achieving a land degradation-neutral world”.This objective is achieved by the integration of already existing databases (interoperability) at different scales with the development of high performance modelling engines simulating agriculture & forestry, land degradation and environmental issues (e.g.fate of pollutants, ecosystem services). All the above, including their validation by remote sensed data will be ensured by a technology at the state of art for the developing environment (i.e.COMPSs), high-performing computing (e.g.GPU) and massive raster data management (e.g.RASDAMAN). LANDSUPPORT will be applied at four geographic scales: EU; 3 Nations (Italy, Hungary, Austria); 2 European Regions in IT and HU; 3 pilot sites in AU, IT, HU; and 2 pilot sites in Tunisia and Malaysia. By doing that, LANDSUPPORT will reconcile grand agriculture/environmental sustainability policy ambitions with operational reality as required by RUR-03-2017 call such as the evaluation of “land use trade-offs” and “incentivizing real actions/behaviour/investments”; all requiring activities at detailed spatial scale. LANDSUPPORT fits with the priorities of this work programme, as LANDSUPPORT S-DSS is (i) a scientific and technology innovation as driver for rural development, (ii) a framework for innovation and new business models adapted to the rural context, (iii) support for skills development in rural communities, (iv) a new approach towards policies and governance (subarea 1).
