    FOOD SYSTEMS ARE EVOLVING QUICKLY TO MEET GROWING AND CHANGING DEMAND, BUT THEY ARE NOT SERVING EVERYONE’S NEEDS. As we modernize food systems to make them climate-smart, healthy, and sustainable, we must also strive to make them inclusive of smallholders, youth, women, conflict-affected people, and other poor and marginalized people.

    Agricultural growth will prove essential for improving the welfare of the vast majority of Africa’s poor. Roughly 80 percent of the continent’s poor live in rural areas, and even those who do not will depend heavily on increasing agricultural productivity to lift them out of poverty. Seventy percent of all Africans— and nearly 90 percent of the poor—work primarily in agriculture. As consumers, all of Africa’s poor—both urban and rural—count heavily on the efficiency of the continent’s farmers.

    Brazilian environmental law imposes more restrictions on land-use change by private landowners in riparian forests than in non-riparian forest areas, reflecting recognition of their importance for the conservation of biodiversity and key ecosystem services. A 22-year time series of classified Landsat images was used to evaluate deforestation and forest regeneration in riparian permanent preservation areas over the past two decades, focusing on the municipality of Paragominas in the state of Pará in eastern Amazonia.

    CONTEXT: Century-long interaction between societies and their environment has shaped the cultural landscapes across Europe. Specific farming systems have persisted for long periods, and their abandonment has led to far-reaching and rapid changes in patterns of land use and land cover. OBJECTIVE: Taking the example of the municipality of Limpach, located in the Swiss lowlands, we studied the dynamics of cultural landscape and related driving forces in a long-term perspective.

    Remotely sensed land cover data can be a tremendous resource to land use decision makers, yet there is often a disconnect between the worlds of remote sensing and local government. The Connecticut’s Changing Landscape project is focused on bridging this gap. The project analyzes changes to the state’s landscape using Landsat-derived 30-m land cover and cross-correlation analysis. It includes seven dates spanning 30 years, from 1985 to 2015.

    Increasing dissolved organic carbon (DOC) concentrations in lakes, rivers and streams in northern mid latitudes have been widely reported during the last two decades, but relatively few studies have dealt with trends in DOC export. We studied the export of DOC from Finnish rivers to the Baltic Sea between 1975 and 2010, and estimated trends in DOC fluxes (both flow normalised and non-normalised). The study encompassed the whole Finnish Baltic Sea catchment area (301,000km²) covering major land use patterns in the boreal zone.
