Luonnonvarojen käyttö ja tasa-arvoinen koulutus#

Sukupuolten välinen tasa-arvo on maailmanlaajuisesti yksi UNESCO:n päätavoitteista. Vaikkakin tämän osalta ollaan otettu isoja edistysaskelia, epätasa-arvoa esiintyy esimerkiksi koulutuksessa monissa eri yhteyksissä. Koulutus tarjoaa lapsille mahdollisuuden vaikuttaa tulevaisuuteensa ja olla osana yhteiskuntaa. Vaikka mahdollisuus laadukkaaseen koulutukseen on ihmisoikeusasia, sillä on myös vaikutusta siihen, minkälaiseksi meidän maailma ja yhteiskunnat kehittyvät. Tyttöjen koulutukseen panostamisella onkin merkittäviä vaikutuksia erityisesti kehittyvissä maissa, sillä se mahdollistaa esimerkiksi nopeamman kehityksen ja hillitsee väestönkasvua.

Luonnonvarojen ja fossiilisten polttoaineiden käyttö on mahdollistanut valtioiden rikastumisen ja nopean kehityksen. Tutkimusten mukaan naisten koulutus on yksi merkittävistä tekijöistä, joka selittää valtioiden eroja sosiaalisen ja tauloudellisen kehityksen osalta [1], ja jolla on tutkitusti positiivinen korrelaatio molempiin [2][3]. Tämän pohjlta voidaankin tarkastella lähemmin sitä, onko valtioiden fossiilisten polttoaineiden kulutuksen myötä mahdollistettu myös tyttöjen pääsyä perusopetusta vastaavaan koulutukseen.


Osio 1. Datasettien valinta#

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
  1. Ratio girls/boys in school, primary and secondary education (%) -datasetti on otettu täältä.

Maakohtainen suhdeluku siitä, missä suhteessa poikia ja tyttöjä osallistuu perusopetusta vastaavaan opetukseen.

  1. Consumption CO2 per capita -datasetti on otettu täältä.

Maakohtaiset tiedot siitä, kuinka paljon fossiilisten polttoaineiden kulutuksesta, sementin valmistuksesta ja maakaasun soihduttamisesta on aiheutunut CO2-päästöjä yhtä asukasta kohden. Tässä luvussa on otettu huomioon maan vienti ja tuonti. Taulukossa annetut luvut ovat tonnia/henkilö.

  1. Fossil fuel consumption per capita -datasetti on otettu täältä.

Maakohtaiset tiedot fossiilisten polttoaineiden kulutuksesta laskettuna yhtä asukasta kohden. Taulukko sisältää öljyn, maakaasun ja kivihiilen kulutukset kilowattitunneissa [kWh].

Osio 2: Datan valmistelu#

Nyt kun itse datasetit ovat valittuna, voidaan pyöräyttää muutama rivi koodia, jotta saadaan valmisteltua datat kuvaajien tekemistä varten.

### Tämän solun ajamisesta seuraa punainen virheilmoitus, mutta siitä ei tarvitse välittää. ###

# Koska fossiilisten polttoaineiden datasetti sisältää erikseen tiedot öljyn, kivihiilen ja maakaasun
# kulutuksesta, niin lasketaan ensin jokaiselle vuodelle erikseen näiden kaikkien kulutuksen summa
# ja lisätään ne tiedot uuteen sarakkeeseen alkuperäiseen taulukkoon. Uuden sarakkeen nimi on nyt "Yht".

yht = np.zeros(len(fossiiliset_polttoaineet_data))
fossiiliset_polttoaineet_data["Yht"] = yht
