Food production in Nigeria is largely dependent on natural environmental resources like rainfall, temperature and relative humidity. This study examined the impact of some of these climatic variables on food production in Nigeria from to The ADF test reveals that relative humidity integrated at order zero level while rainfall and temperature and agricultural output were stationary after differencing at level 1 thus showing that the variables had relationship. It was recommended, therefore, that measure that could help to mitigate the adverse effects of inadequate rainfall e. Farmers should equally be sensitized and trained in the area of adaptation and mitigation of the effect of climate change as this will go a long way to ameliorate large scale failure in food production in the country.
As the global population grows and incomes in poor countries rise, so too, will the demand for food, placing additional pressure on sustainable food production. Climate change adds a further challenge, as changes in temperature and precipitation threaten agricultural productivity and the capacity to feed the world's population. This study assesses how serious the danger to food security might be and suggests some steps policymakers can take to remedy the situation. Using various modeling techniques, the authors project 15 different future scenarios for food security through Each scenario involves an alternative combination of potential population and income growth and climate change.
Climate change and agriculture are interrelated processes, both of which take place on a global scale, with the adverse effects of climate change affecting agriculture both directly and indirectly. This can take place through changes in average temperatures , rainfall , and climate extremes e. Climate change is already affecting agriculture, with effects unevenly distributed across the world. Agriculture contributes towards climate change through anthropogenic greenhouse gas emissions and by the conversion of non-agricultural land such as forests into agricultural land. A range of policies can reduce the risk of negative climate change impacts on agriculture   and greenhouse gas emissions from the agriculture sector. The agricultural sector is a driving force in the gas emissions and land use effects thought to cause climate change. In addition to being a significant user of land and consumer of fossil fuel , agriculture contributes directly to greenhouse gas emissions through practices such as rice production and the raising of livestock;  according to the Intergovernmental Panel on Climate Change , the three main causes of the increase in greenhouse gases observed over the past years have been fossil fuels, land use, and agriculture.
Climate change negatively affects all four pillars of food security: availability, access, utilisation and stability. Food availability may be reduced by negative climate change impacts on productivity of crops, livestock and fish, due, for instance, to increases in temperature and changes in rainfall patterns. Productivity is also negatively affected by increased pests and diseases, as well as changing distributions of pollinators under climate change. Food access and its stability may be affected through disruption of markets, prices, infrastructure, transport, manufacture, and retail, as well as direct and indirect changes in income and food purchasing power of low-income consumers. Food utilisation may be directly affected by climate change due to increases in mycotoxins in food and feed with rising temperatures and increased frequencies of extreme events, and indirectly through effects on health. Elevated atmospheric CO2 concentrations can increase yields at lower temperature increases, but tend to decrease protein content in many crops, reducing their nutritional values. Extreme events, for example, flooding, will affect the stability of food supply directly through disruption of transport and markets.
Adapting to Climate Change pp Cite as. The possible effects of global warming on agriculture may have economic, ecological, and social repercussions. Major factors in analyzing these effects include expected population growth, possible increases in agricultural production, improved agrotechnology, and changes in crop productivity. Favorable climate changes, especially the effect of increased carbon dioxide CO 2 on crop productivity, can help to solve the food supply problem expected in the 21st Century.
Food may be a universal language — but in these record-breaking hot days, so too is climate change. With July clocking in as the hottest month on Earth in recorded history and extreme weather ramping up globally, farmers are facing the brunt of climate change in croplands and pastures around the world.

As the evidence base grows, it becomes increasingly clear: the link between climate change and global instability often runs through our food systems. The link between climate change and global instability often runs through our food systems. That conflict is on the rise around the world is unmistakable.
Data underlying the study are government reported data and are publicly available from the links in S1 Text. The authors confirm they did not have any special access to this data that others would not have. Yield data for the studied regions for the top four global crops are in S8 Table. Crop yields are projected to decrease under future climate conditions, and recent research suggests that yields have already been impacted. However, current impacts on a diversity of crops subnationally and implications for food security remains unclear. We find that the impact of global climate change on yields of different crops from climate trends ranged from

Techniques related to agrotechnology, climate, and crop productivity contribute to a balanced strategy for adapting to future global changes. Skip to main content Skip to sections.
Какая разница. Давай сотню песет. Обменные операции явно не относились к числу сильных сторон Двухцветного: сто песет составляли всего восемьдесят семь центов.
Беккер почувствовал комок в горле. - Когда она уезжает. Двухцветный словно будто только что очнулся.
Сьюзан покачала головой. - Такие перестановки - стандартный прием.
Беккер посмотрел внимательнее. В свете ламп дневного света он сумел разглядеть под красноватой припухлостью смутные следы каких-то слов, нацарапанных на ее руке. - Но глаза… твои глаза, - сказал Беккер, чувствуя себя круглым дураком. - Почему они такие красные.

Это какая-то глупая шутка. Он не находил слов. - Ты знаешь ее фамилию.
