Kutoka Wikipedia, kamusi elezo huru

Mabadiliko ya tabianchi Mashariki ya Kati na Afrika Kaskazini (MENA Middle East and North Africa) ni makala inayoelezea mabadiliko ya tabianchi ya eneo la Mashariki ya Kati na kaskazini mwa Afrika pamoja na mikakati ya baadaye ya namna ya kukabiliana na hali ya mabadiliko hayo. [1]

Matokeo ya mabadiliko

[hariri | hariri chanzo]

Mabadiliko hayo yanaonekana hasa katika

  • kupanda kwa halijoto; idadi za siku zenyo joto la juu imeshaongezeka mara mbili kazi ya 1970 na 2016.[2] Utafiti wa kisayansi unatabiri kwamba vipindi vya joto kali vitatokea kwa siku 80 za mwaka mnamo 2050 na siku 118 za mwaka manmo 2100.[3] Pamoja na kuongezeka kwa dhoruba za mchanga na vipindi virefu vya ukame sehemu kubwa za MENA zinaweza kugeukia kuwa kiadui kwa maisha ya kibinadamu.
  • uhaba wa maji: tayari leo maji ni haba sana katika nchi za MENA.[4] Benki ya Dunia inafafanua eneo kuwa na changamoto ya maji kama akiba ya maji iko chini ya mita za ujao 1700 kwa mwaka kwa kila mkazi wa eneo.[5] Utafiti wa Shirika la Mpango wa Chakula Duniani (WFP) inatabiri kwamba kiasi cha mvua itapungua zaidi na kusababisha kushuka kwa mavuno kwa asilimia 30 hadi mwaka 2050.[6] Mabadiliko hayo yataathiri sana jumuiya zote zinazotegemea kilimo.
  • kupanda kwa usawa bahari wastani: katika nchi za MENA, watu milioni 60 hukalia maeneo karibu na pwani la bahari. Hadi mwaka 2030 idadi hii inatabiriwa kufikia miloni 100.[7][8] Kupanda kwa usawa bahari wastani kutasababisha mafuriko na bahari kuenea hadi sehemu zinazokaliwa na binadamu. Nchi itakayoathiriwa zaidi ni Misri. Leo hii sehemu kubwa za mji wa Aleksandria [9] na theluthi moja ya delta ya mto Nile ni nchi iliyopo kidogo juu ya usawa bahari wastani na wakati wa dhoruba maji yanaingia tayri kwenye nchi kavu. Kupanda kwa usawa wa bahari kwa mita moja kungezamisha asilimia 12-15 za ardhi ya mashamba ya Misri kwenye bahari[10] na kulazimisha wakazi milioni 6-7 kuhama. Hata kupanda kwa sentimita 50 pekee kungelazimisha watu milioni 2 kuhama.

Michango ya nchi za MENA kwa uzalishaji wa gesi chafu

[hariri | hariri chanzo]

Mnamo 2018, eneo la MENA lilitoa tani bilioni 3.2 za kaboni dioksidi na 8.7% ya uzalishaji wa gesi chafu duniani (GHG) [11] licha ya kuwa na asilimia 6 pekee ya watu duniani. [12]

Uzalishaji huu mara nyingi unatoka kwenye viwanda vya nishati, [13] kwa kua sehemu ya nchi nyingi za Mashariki ya Kati na Afrika Kaskazini kuwa na hifadhi kubwa ya mafuta na gesi asilia ambayo hupatikana katika maeneo aya. [14] [15] Eneo la Mashariki ya Kati ni mojawapo ya maeneo yaliyo hatarini zaidi kwa mabadiliko ya hali ya hewa. Athari hizo ni pamoja na kuongezeka kwa hali ya ukame, Wimbi la joto|hali ya joto na kuongezeka kwa kina cha bahari.
