Road expansion has played a prominent role in the agrarian transition that marked the integration of swidden-based farming systems into the market economy in Southeast Asia. Rural roads deeply altered the landscape and livelihood structures by allowing the penetration of boom crops such as hybrid maize in remote territories. In this article, we investigate the impact of rural road developments on livelihoods in northern Laos through a longitudinal study conducted over a period of 15 years in a forest frontier.

The Multi-Level Perspective (MLP) is an analytical framework developed to explain transitions towards sustainability. This article aims to contribute to enhancing the use of the MLP to understand the transitions towards sustainability in agriculture. We propose that MLP is an insightful framework to capture particular micro-level trajectories of adopting innovations. The Douro wine region in Northern Portugal, known worldwide for the wines that are produced there, was the study area of our empirical research.

There is a lack of understanding of the main drivers that form the picture of biological communities of transitional waters in deltaic ecosystems under the influence of terrestrial sources. Analysis of hydrochemical parameters in relation to phytoplankton communities in the Ukrainian part of the Danube coastal zone (in August 2018) is the focus of current work. The goal was to identify patterns in the distribution of environmental parameters (salinity and nutrients) in the area of the shipping channel through the Bystry arm, as well as to assess the state of water quality.
