Human use of land has been transforming Earth's ecology for millennia. From hunting and foraging to burning the land to farming to industrial agriculture, increasingly intensive human use of land has reshaped global patterns of biodiversity, ecosystems, landscapes, and climate. This review examines ...recent evidence from archaeology, paleoecology, environmental history, and model-based reconstructions that reveal a planet largely transformed by land use over more than 10,000 years. Although land use has always sustained human societies, its ecological consequences are diverse and sometimes opposing, both degrading and enriching soils, shrinking wild habitats and shaping novel ones, causing extinctions of some species while propagating and domesticating others, and both emitting and absorbing the greenhouse gases that cause global climate change. By transforming Earth's ecology, land use has literally paved the way for the Anthropocene.

This Study presents the key results of a research that analyses the implications of an ambitious agroecological transition across Europe, following the TYFA scenario. Published in 2018, what it proposes by 2050 is fully aligned with the objectives that the European Farm to Fork and Biodiversity stra...tegies aim to achieve by 2030, in particular regarding the decrease in pesticides, nitrogen, and antibiotics on the supply side, and the transition towards more plant-based diets on the demand side. Using a world biomass balance model (GlobAgri-AgT), the impact of the TYFA scenario in the EU on world land use, the EU physical trade balance, the provision of calories and global food security is analysed in addition to key policy levers to spur the transition.

PlosOne https://doi.org/10.1371/journal.pone.0165797; Food production is a major driver of greenhouse gas (GHG) emissions, water and land use, and dietary risk factors are contributors to non-communicable diseases. Shifts in dietary patterns can therefore potentially provide benefits for both the en...vironment and health. However, there is uncertainty about the magnitude of these impacts, and the dietary changes necessary to achieve them.

The Arab region in the Middle East and North Africa (MENA) represents a substantial area of the terrestrial landmass encompassing several countries and ecosystems. This area is generally drier and warmer compared to the rest of the world and has extreme resource limitations that are highly vulnerabl...e to a changing climate, geopolitical instability and land degradation (Slimani & Aidoud, 2004). Agriculture (crops and livestock) is a critical source of employment and a potential option for engaging rural youth. However, environmental degradation coupled with declining and variable agricultural productivity may pose a massive challenge already beset by instability and declining oil reserves (Tagliapietra, 2017). The Arab region is also subjected to short and long-duration climate extreme events, and the overall impact of their cascading effects on ecosystems, societies and economies is still an open question. Climate change, along with post-war geopolitical complexities, has greatly affected the Arab region in terms of its economy and social balance. Climate change has penetrating effects on the region’s agriculture sector and hence its economy. These are mainly manifested via changes in water resources and extreme weather conditions such as heatwaves and a drastic decline in precipitation.

Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

Urbanization, land use, global trade and industrialization have led to profound and negative impacts on nature, biodiversity and ecosystems across the world. The ongoing depletion of natural resources not only afects environmental conditions but also has an enormous impact on the well-being and secu...rity of societies.
This report provides an overview of the impacts of the natural environment on human health. It presents the ways nature and ecosystems can support and protect health and well-being, and describes how nature degradation and loss of biodiversity can threaten human health.

In March, households in Lofa used fewer negative coping strategies than in February. The counties with highest levels of negative coping include Bomi, Grand Cape Mount, Gbarpolu and Lofa.
Negative coping strategies are most frequently used by the poorest households, by those living in Ebola...-affected rural areas and by households headed by women.
Imported and local rice prices remained stable. As the land preparation season advances, wage rates are improving (+3% compared to February).

Arsenic contaminated tube well water was first detected in Bangladesh in early 1990s. The arsenic comes from naturally arsenic-rich material delivered by the region's river systems, deposited over many years to make up the land of Bangladesh. Arsenic contamination is not caused by tube wells, or by ...irrigation or application of fertilizers.
Today, although 98 per cent of the population uses an improved drinking water source the safe water coverage of Bangladesh is 86 per cent because of arsenic contamination.

The National Strategy for Natural Disaster, Prevention, Response and Mitigation to 2020, which outlines Vietnam’s main disaster risk management objectives and the National Target Program (NTP) form the overarching policy framework for disaster risk management and climate change adaption activities.... The CCFSC’s main mandate is to translate this strategy into action. Other decrees and laws are also complementary. The Government of Vietnam has prioritized disaster preparedness, recognizing that the most cost-effective measures to mitigate flood related disasters are often non-structural. These measures include flood mapping, river flood warning systems, television-based disaster information and warning systems, training at all government and grassroots levels on disaster preparedness, and reforestation of certain areas. Land use and development have also been addressed through government regulations.

Over the ages, human societies have altered local ecosystems and modified regional climates. Today the human influence has attained a global scale. This reflects the recent rapid increase in population size, energy consumption, intensity of land use, international trade and travel, and other human a...ctivities. These global changes have heightened awareness that the long-term good health of populations depends on the continued stability of biosphere's ecological, physical and socioeconomic systems.
The world's climate system is an integral part of the complex of life-supporting processes. Like other large systems, the global climate system is coming under pressure from human activities.
This book seeks to describe the context and process of global climate change, its actual or likely impacts on health, and how human societies and their governments should respond with particular focus on the health sector.
