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.

An IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems
As more frequent droughts and floods threaten the global food supply, humans are increasing their demands on water and land,... The New York Times reports.
Data from the Intergovernmental Panel on Climate Change report:
• 500 million people are living in areas that are becoming desert.
• Soil is depleted at 10X-100X the rate it’s being formed.
• More than 10% of the global population is undernourished.
Major threats include the risk of “multi-breadbasket failure”—simultaneous food crises on several continents—and migration triggered by food shortages.
Good News/Bad News: Catastrophe can be avoided, but it would require massive changes to agriculture, food systems and behavior.
A Key Action: Eat less meat. Cattle production is driving deforestation, consuming huge amounts of water, generating methane and causing other impacts, notes Nature.

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.

As scientists of the UN’s Intergovernmental Panel on Climate Change meet in Geneva this week to publish their Special Report on Climate Change and Land (August 8), a new report by the development charity Christian Aid shows that climate change is having a disproportionate impact on the food systems of the country’s least responsible for causing the climate crisis.
The IPCC is expected to show how climate change will affect global food supply, spiking prices and reducing nutrition. It is also likely to recommend that countries will need to drastically cut emissions if global food security is to be protected.

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.

Climate change is a growing concern for Bangladesh because 90 percent of the country is approximately 10 feet above sea level. An evaluation was completed which discovered that high tides in Bangladesh were increasing 10 times more rapidly than the global average. This predicted rapid increase in se...a levels places Bangladesh four times higher than the global average. By 2050, approximately 20 percent of the inhabited land in Bangladesh will be inundated by the sea resulting in displacement for nearly 20 million people. The Government of Bangladesh has implemented policies and plans to focus on climate change concerns, but there is still much work to be completed.
Bangladesh is a nation which will continue to experience the devastating effects of climate change. These concerns for the nation are recognized and the Government of Bangladesh is working progressively to implement mitigation and preparedness measures along with making national economic and transportation improvements to better sever and protect the people of Bangladesh.

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.
