Após uma revisão das combinações terreno-arquivo em trabalhos prévios, abordo as migrações de madeirenses e açorianos para o Hawaii.
Employing a linkage between a biophysical and an economic model, this study estimates the economic impact of soil erosion by water on the world economy. The global biophysical model estimates soil erosion rates, which are converted into land productivity losses and subsequently inserted into a global market simulation model. The headline result is that soil erosion by water is estimated to incur a global annual cost of eight billion US dollars to global GDP.

This reflection paper focuses on the baobab value chain in the north of Manica Province, and specifically on the interactions between women baobab collectors and Baobab Products Mozambique (BPM), as BPM seeks to develop its inclusive business model.
For the last three years, the commercial interactions between BPM and the communities, particularly the women who collect the baobab fruit, have taken place in the context of a LEGEND-funded project implemented by Micaia Foundation. Micaia’s project sought to address two central problems:
Recognizing the extensive literature available on outgrower cooperative farming, this case study seeks to add to this literature by providing in-depth learnings and guidance on good practices for structuring commercial, cooperative outgrower schemes in Malawi and potentially elsewhere.
Smallholder farmers in the mid-hills of Nepal are facing an acute labor shortage due to out-migration which, in general, has affected the capacity to achieve timely crop establishment, harvest, and inter-cultural operations. These effects are more visible in the case of labor-intensive crops such as rice and promoting higher levels of rural mechanization has emerged as the primary policy response option. Nevertheless, quantitative evidence for the ability of mechanization to offset the adverse effects of shortages increasing labor prices in these systems is largely absent.
Agriculture around the world is one of the industries most affected by, and faced with responsibility to mitigate, climate change. Through improvements in technology and efficiency as well as changes to land use management, agriculture can make an important contribution to meeting global commitments such as the Paris agreement or the Sustainable Development Goals. Yet international carbon markets have not resulted in sufficiently high financial returns to motivate the full potential of land sector changes in Australia and globally.
Agriculture in Eastern Europe and Central Asia is diverse, and has great potential to revitalize the economy of the countries in the region via improved productivity (efficiency) and higher total yield for food, fodder and fibre crops. Conservation agriculture can rise to the major challenge of making sustainable intensification of production systems a reality.
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.
It’s been ten years since open data first broke onto the global stage. Over the past decade, thousands of programs and projects around the world have worked to open data and use it to address a myriad of social and economic challenges. Meanwhile, issues related to data rights and privacy have moved to the centre of public and political discourse. As the open data movement enters a new phase in its evolution, shifting to target real-world problems and embed open data thinking into other existing or emerging communities of practice, big questions still remain.
