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).

Climate change may increase the importance of agriculture in the global Circumpolar North with potentially critical implications for pristine northern ecosystems and global biogeochemical cycles. With this in mind, a global online survey was conducted to understand northern agriculture and farmers’ perspective on environmental change north of 60° N.

Population densities and diurnal activity pattern of the Indian Roller were studied in Nagapattinam District over three years in different habitats. The agricultural lands supported the highest populations (41km-2), followed by river banks (36km-2) and social forests (32km-2); populations showed yearly variations in numbers and density in all habitats. On average, birds were observed to spend most of the day scanning (57%), with the remainder divided among feeding (16%), flying, (12%), preening (10%) and resting (5%).

Mediterranean regions have experienced a shift from accelerated urban growth typical of a post-industrial phase to a more recent spatial delocalization of population and economic activities reflecting discontinuous settlement expansion, land take, and the abandonment of cultivated areas around central cities. On the basis of a comprehensive analysis of land-use, settlement, and demographic indicators, the present study explores urban growth and population density over a sufficiently long time period in a metropolitan region of Southern Europe (Rome, Italy).

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.

WEB INTRODUCTION: The literature on agricultural large-scale land acquisition in Myanmar is rather fragmented and consists mainly of case studies. While these provide key insights into particular stories, they often fail to identify the main patterns and trends at country level. To fill such gaps, this thematic study aims to present an updated synthesis of the genealogy, institutional complexity and the ins and outs of large-scale land acquisition processes for agricultural development in Myanmar.

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.

Mainstream analysis of contemporary livelihood transformations and rural development in the upland regions of Southeast Asia has hitherto focused primarily on the role of agricultural commercialization and cash crops. This is reflected in policy narratives that conflate the fortunes of rural households to the expansion of a particular kind of entrepreneurial agriculture. In this article, we problematize the dynamics of economic and social change in the little-studied uplands of Chin State, Myanmar, against this policy backdrop.

The core neoliberal strategy of Chilean agrarian politics has lasted now for more than 30 years. Despite minor reforms, its fundamental pillars remain in place. While members of the agribusiness sector consider this strategy to be a role-model for food production leading to explosive economic growth, the last decade exposed its socio-ecological limits, such as declining water availability and increased conflicts over land.

Groundwater resources became a recognized enabler of important rural and socio-economic development in Mediterranean countries. However, the development of this groundwater economy is currently associated with an increased pressure on the available resource and negative implications on the socio-ecological system. Managing complex socio-ecological systems, such as those that occur in water resource management, is a multi-actor, multi-scale and dynamic decision-making process.
