Climate is a primary determinant of agricultural productivity. Climate change or global warming is caused by the release of greenhouse gases into the atmosphere. All climate models predict an increase in surface temperature for the next century. However, regional precipitation is predicted poorly, and the models often disagree even on the direction of precipitation change over most areas. Since plant growth and crop production are controlled by weather, it is important to understand the implications of such weather changes on agriculture. This paper examines the most recent research findings on possible climate change effects on agriculture.

İklim değişikliği ve tarım üzerindeki etkileri

Öz

İklim tarımsal üretimi belirleyen temel faktördür. İklim değişikliği ya da küresel ısınma atmosfere sera gazlarının yayılmasından kaynaklanmaktadır. Tüm iklim modelleri gelecek yüzyılda yeryüzü sıcaklığının artacağını öngörmektedir. Bununla birlikte, bölgesel yağışla ilgili kesin tahminler yapılamamaktadır. Yine birçok bölgede yağıştaki değişimin yönüne dair oluşturulan modeller arasında da genel bir uyum bulunmamaktadır. Bitki büyümesi ve yetiştiriciliği hava olayları tarafından kontrol edildiği için bu tür değişikliklerin tarım üzerindeki sonuçlarının anlaşılması büyük bir önem arz etmektedir. Bu çalışma, olası iklim değişikliğinin tarım üzerine etkilerine ilişkin yapılan son araştırma bulgularını ele almaktadır.
