Human beings have learned to live with climate variability on various timescales, from daily to decadal. However, the climate variability we are accustomed to is changing quickly, accompanied by a rise in global mean temperature due to increasing greenhouse-gas concentrations in the atmosphere.

Source: Andrew J. Challinor et al. Addressing food system impacts from climate change is not merely an environmental challenge, it is a human development imperative. As the evidence base grows, it becomes increasingly clear: the link between climate change and global instability often runs through our food systems.

Climate change and variability in Kenya: a review of impacts on agriculture and food security

Climate change and variability are a major threat to the agricultural sector globally. It is widely accepted that the changes in temperature, rainfall patterns, sea water level and concentration of CO 2 in the atmosphere will have the most devastating impacts on agricultural production. This paper examines the past and future crop production and food security in Kenya under variable climate.

From the review, it is evident that the country is already experiencing episodes of climate change, manifested by seasonal changes in precipitation and temperature of varying severity and duration despite overreliance on rain-fed agriculture.

The findings also reveal that climate change would continue to negatively affect crop production and food security to the already vulnerable communities in the arid and semi-arid areas. Future projections also indicate that climate variability will likely alter cropping patterns and yields in several regions. As the country is faced with a high population growth rate and rapid urbanization, crop production and food security systems need to become more adaptive as uncertainties of projected climate variability and change unfold.

This study is important in providing decision makers and interested stakeholders with a detailed assessment of climate impacts and adaptation strategies geared towards improved crop production and food security.

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 [9] [10] and greenhouse gas emissions from the agriculture sector.

Food Security Under a Changing Climate

Metrics details. However, farming has been constrained by the mountainous topography and rapid changes in environmental variabilities. With climate change, agricultural production and food security is likely to face one of the biggest challenges of the twenty-first century.

Climate Change and Food Security

 - Мисс Флетчер, вы проделали уже немалую часть пути. Постарайтесь пройти по нему до конца. Сьюзан вздохнула: - Программа принимает ключ только в цифровой форме.

Чем могу служить, сеньор? - Он говорил нарочито шепеляво, а глаза его внимательно осматривали лицо и фигуру Беккера. Беккер ответил по-испански: - Мне нужно поговорить с Мануэлем. Загорелое лицо консьержа расплылось еще шире. - Si, si, senor. Мануэль - это. Чего желаете. - Сеньор Ролдан из агентства сопровождения Белена сказал мне, что вы… Взмахом руки консьерж заставил Беккера остановиться и нервно оглядел фойе.

Дэвид Беккер смотрел на экран прямо перед. У него кружилась голова, и он едва отдавал себе отчет в происходящем. На экране он видел комнату, в которой царил хаос. В этой комнате находилась Сьюзан. Она стояла отдельно от остальных и смотрела на него, смеясь и плача. - Дэвид… Слава Богу.

 - В голосе мужчины чувствовалось какая-то озабоченность.  - Я нашел его в паспорте и хочу разыскать владельца. Сердце Ролдана упало.

 Дипломатическая любезность? - изумился старик. - Да, сэр. Уверен, что человеку вашего положения хорошо известно, что канадское правительство делает все для защиты соотечественников от неприятностей, которые случаются с ними в этих… э-э… скажем так, не самых передовых странах. Тонкие губы Клушара изогнулись в понимающей улыбке. - Да, да, конечно… очень приятно.

 - Я поняла это, сделав пробу системных функций. Мы выделили отдаваемые им команды - смотрите. Смотрите, на что он нацелен.

 - Периодическая таблица. Химические элементы. Видел ли кто-нибудь из вас фильм Толстый и тонкий о Манхэттенском проекте. Примененные атомные бомбы были неодинаковы. В них использовалось разное топливо - разные элементы.

Последний месяц был для Лиланда Фонтейна временем больших ожиданий: в агентстве происходило нечто такое, что могло изменить ход истории, и, как это ни странно директор Фонтейн узнал об этом лишь случайно. Три месяца назад до Фонтейна дошли слухи о том, что от Стратмора уходит жена. Он узнал также и о том, что его заместитель просиживает на службе до глубокой ночи и может не выдержать такого напряжения. Несмотря на разногласия со Стратмором по многим вопросам, Фонтейн всегда очень высоко его ценил.

Сьюзан чуть не свалилась со стула.

    Climate change negatively affects all four pillars of food security: availability, access, utilisation and stability.

    The consequences of climate change for agriculture and food security in developing countries are of serious concern.
