Evidence: 100 • authority: 72

Climate change for Washington State, in the United States, has major implications on the quality of factors like health, agriculture, air quality, sea levels, and wildlife. Greenhouse gas (GHG) emissions continue to rise in concentration, destroying the ozone layer and leading to uncharacteristic rises and falls in temperature that continue the cycle of GHG production in attempts at mitigating the temperature changes. Increased temperatures cause annual snowmelt peaks and glacial melt to occur earlier in the year, resulting in reduced water availability in the summertime. Crops and brush become drier and more flammable, increasing the number of wildfires and destroying the habitats of anima…

There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security. Recent research has found that climate change is likely to exacerbate the existing environmental impacts of agriculture by lowering crop productivity, reducing the effectiveness of agrochemicals, increasing soil erosion and pest pressures, and thereby driving greater use of land, water and inputs. Rising temperatures and changing weather patterns often result in lower crop yields due to water scarcity caused by drought, heat waves and flooding. These effects of climate change can also increase the risk of several regions suffering simul…

Climate change in Nigeria has caused increasing temperatures and rainfall variability (increasing in coastal areas and declining in continental areas) resulting in drought, desertification, rising sea levels, erosion, floods, thunderstorms, bush fires, landslides, land degradation and more frequent, extreme weather conditions. Climate change is leading to biodiversity loss, reduced food and water security, increasing poverty, conflict, displacement, economic instability and negative health outcomes in Nigeria. Nigeria is highly vulnerable to and not well prepared to deal with the effects of climate change. The agricultural sector is particularly most vulnerable. Nigeria is in the top 25 hig…

Climate change in Africa is a serious threat because the continent is one of the most vulnerable regions to the effects of climate change, despite being responsible for less than 4% of global greenhouse gas emissions. Climate change is causing increasingly erratic rainfall patterns, more frequent extreme weather events such as droughts and floods, and rising sea-surface temperatures across the continent. These changes threaten food and water security, biodiversity, public health, and economic development. Africa is currently warming faster than the rest of the world on average. Climate change intensifies existing socioeconomic vulnerabilities. Large segments of the African population depend…

Challenges to food security in a changing environment: a community-based participatory research study in Casamance, Senegal (West Africa).. Introduction Environmental change is accelerating across West Africa, placing increasing pressure on communities whose livelihoods depend on smallholder and subsistence farming. In Senegal's Casamance region, shifting rainfall patterns, rising temperatures, soil salinization, and deforestation are undermining food production and altering culturally significant landscapes, including sacred forests. While ecological changes are well documented, fewer studies examine how local communities interpret these transformations and how these perceptions relate to…

Climate change and agriculture are complexly related processes. In the United States, agriculture is the second largest emitter of greenhouse gases (GHG), behind the energy sector. Direct GHG emissions from the agricultural sector account for 8.4% of total U.S. emissions, but the loss of soil organic carbon through soil erosion indirectly contributes to emissions as well. While agriculture plays a role in propelling climate change, it is also affected by the direct (increase in temperature, change in rainfall, flooding, drought) and secondary (weed, pest, disease pressure, infrastructure damage) consequences of climate change. The United States Department of Agriculture (USDA) is a regulato…

Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate system. In a broader sense, climate change also includes previous long-term changes to Earth's climate. The modern-day rise in global temperatures is driven by human activities, especially fossil fuel (coal, oil and natural gas) burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases. These gases absorb some of the heat that the Earth radiates after it warms from sunlight, warming the lower atmosphere. Earth's atmosphere now has roughly 50% more carbon dioxi…

Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall warming trend, changes to precipitation patterns, and more extreme weather. As the climate changes it impacts the natural environment with effects such as more intense forest fires, thawing permafrost, and desertification. These changes impact ecosystems and societies, and can become irreversible once tipping points are crossed. Climate activists are engaged in a range of activities around the world that seek to ameliorate these issues or prevent them from happening. The effects of climate change vary in timing and location. Up until…

Tradeoffs in climate adaptation? Early data suggest reducing livelihood risks does not change health risks for mobile herders.. Introduction Climate events like drought adversely affect the health and livelihoods of mobile or migrant communities. Individuals take various actions to reduce these risks - but how does climate adaptation in one domain, like livelihood, potentially increase risk in another, like health? How might actions to reduce health risks now, like by improving food security, increase health risks later, like to mental health? Methods We present findings from individual surveys (n = 90) and in-depth interviews (n = 16) with Rendille people in northern Kenya that were conduc…

Beyond the silos: A global evidence synthesis of biodiversity, water, food, health and climate nexus interactions.. Healthy, resilient ecosystems depend on biodiversity to provide ecosystem services that are essential for human well-being. However, unsustainable human activities have driven biodiversity loss, ecosystem degradation, and climate change, generating cascading impacts on water, food, and health systems. As part of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Nexus Assessment, we reviewed 1,962 articles and identified 84 that explicitly addressed biodiversity and at least three other nexus elements. Across these studies, we document…

Adaptive policies balancing trade, productivity and cropland increases can support Zambia's nutrition security under future climate shocks.. Policies in sub-Saharan Africa are constrained by a limited knowledge of climate change extremes and a focus on agricultural production rather than nutrition supply. Here we model the impacts of future extremes on national-level calorie and nutrient supply in Zambia for production and nutrition focused policy scenarios. We identify the specific cropland, yield and import increases required to achieve climate-resilient nutrition security and highlight policy options..

Intersection of Climate and Environmental Change and Priority Health Outcomes Across the Life Course: Working Group 1 Report from the "Agriculture and Diet: Value Added for Nutrition, Translation, and Adaptation in a Global Ecology" (ADVANTAGE) Project.. An ecological approach examining multiple factors, internal (e.g., genetics and concurrent health status) and external (social determinants of diet/nutrition and physical environment), is essential for a comprehensive understanding of the interactions between climate and environmental change (CEC), nutrition, and health. We present evidence on the intersection of CEC and priority health outcomes across the life course. We include examples o…
