    Land and ecosystems lay the foundation of the economy and the wellbeing of society. 85 percent of the world’s 1.2 billion young people live in regions that are directly dependent on land and natural resources for sustenance. Land degradation is a youth issue that threatens current and future generations’ quality of life. Young people are increasingly becoming eco-anxious about threats to their environment and the possible impacts there may be for future generation.

    High-Resolution Global Maps of 21st-Century Forest Cover Change

    Global

    Quantification of global forest change has been lacking despite the recognized importance of forest ecosystem services. In this study, Earth observation satellite data were used to map global forest loss (2.3 million square kilometers) and gain (0.8 million square kilometers) from 2000 to 2012 at a spatial resolution of 30 meters. The tropics were the only climate domain to exhibit a trend, with forest loss increasing by 2101 square kilometers per year.

    Climate change and agriculture: Strengthening the role of smallholders cover image

    Global

    Smallholder farmers have a vital role to play in global food security and nutrition, and in supporting a range of development and climate change goals. Strengthening the resilience and commercial viability of these farmers, particularly women and youth, can increase their capacity to contribute to these global goals.

    Malnutrition costs the world trillions of dollars, but global commitment to improving people’s nutrition is on the rise, and so is our knowledge of how to do so. Over the past 50 years, understanding of nutrition has evolved beyond a narrow focus on hunger and famine. We now know that good nutrition depends not only on people’s access to a wide variety of foods, but also on the care they receive and the environment they live in. A number of countries and programs have exploited this new understanding to make enormous strides in nutrition.

    Farming the planet: 1. Geographic distribution of global agricultural lands in the year 2000 cover image

    Global

    Agricultural activities have dramatically altered our planet's land surface. To understand the extent and spatial distribution of these changes, we have developed a new global data set of croplands and pastures circa 2000 by combining agricultural inventory data and satellite-derived land cover data. The agricultural inventory data, with much greater spatial detail than previously available, is used to train a land cover classification data set obtained by merging two different satellite-derived products (Boston University's MODIS-derived land cover product and the GLC2000 data set).

    Global food demand and the sustainable intensification of agriculture cover image

    Global

    Global food demand is increasing rapidly, as are the environmental impacts of agricultural expansion. Here, we project global demand for crop production in 2050 and evaluate the environmental impacts of alternative ways that this demand might be met. We find that per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a similarly increasing function of per capita real income since 1960. This relationship forecasts a 100–110% increase in global crop demand from 2005 to 2050.

    Global biomass production potentials exceed expected future demand without the need for cropland expansion cover image

    Global

    Global biomass demand is expected to roughly double between 2005 and 2050. Current studies suggest that agricultural intensification through optimally managed crops on today's cropland alone is insufficient to satisfy future demand. In practice though, improving crop growth management through better technology and knowledge almost inevitably goes along with (1) improving farm management with increased cropping intensity and more annual harvests where feasible and (2) an economically more efficient spatial allocation of crops which maximizes farmers' profit.

    Food Security: The Challenge of Feeding 9 Billion People cover image

    février, 2010
    Global

    Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the environment. The effects of climate change are a further threat. But the world can produce more food and can ensure that it is used more efficiently and equitably.

    Governance and Conflict Relapse cover image

    Global

    Many conflict studies link the sources of social conflicts to sentiments of relative deprivation. They typically regard formal democratic institutions as states’ most important vehicle to reduce deprivation-motivated armed conflict against their governments. We argue that the wider concept of good governance is better suited to analyze deprivation-based conflict. The paper shows that the risk of renewed conflict in countries with good governance drops rapidly after the conflict has ended. In countries characterized by poor governance, this process takes much longer.

    In 2010, the Conference of the Parties to the Convention on Biological Diversity adopted the Aichi Biodiversity Targets as part of the Strategic Plan for Biodiversity 2011-2020. Target 11 calls for ‘at least 17 per cent of terrestrial and inland water areas and 10 per cent of coastal and marine areas’ to be conserved by way of ‘well-connected systems of protected areas and other effective area-based conservation measures’.
