The Yemeni Civil War is an ongoing conflict that began in 2015 between two factions: the then-incumbent Yemeni government, led by Abdrabbuh Mansur Hadi, and the Houthi militia, along with their supporters and allies.
The Houthi movement which is officially know as Ansar Allah, they are Islamic religious-political-armed movement that emerged from Sa'dah in northern Yemen in the 1990s.
Both Abdrabbuh Mansur Hadi and the Houthi movement claim to constitute the Yemeni government.
Houthi forces controlling the capital Sana'a, and allied with forces loyal to the former president Ali Abdullah Saleh, have clashed with forces loyal to the government of Abdrabbuh Mansur Hadi, based in Aden. Al-Qaeda in the Arabian Peninsula (AQAP) and the Islamic State of Iraq and the Levant have also carried out attacks, with AQAP controlling swathes of territory in the hinterlands, and along stretches of the coast.
During this crisis thousands of life have been lost, ranging from 8,670–13,600 according to UN. Also the crisis has lead to increase in starvation of children and Civilians in Yemen which the UN said will be the worst famine of all in 100 years if nothing is done.
On 21 March 2015, after taking over Sana'a and the Yemeni government, the Houthi-led Supreme Revolutionary Committee declared a general mobilization to overthrow Hadi and further their control by driving into southern provinces.
The Houthi offensive, allied with military forces loyal to Saleh, began on the next day with fighting in Lahij Governorate. By 25 March, Lahij fell to the Houthis and they reached the outskirts of Aden, the seat of power for Hadi's government; Hadi fled the country the same day. Concurrently, a coalition led by Saudi Arabia launched military operations by using airstrikes to restore the former Yemeni government and the United States provided intelligence and logistical support for the campaign.
Effects: speaking on the environmental impact of the Yemen crisis, it has lead to the decrease in availability of water in yemen. Water scarcity with an intrinsic geographical formation in highlands and limited capital to build water infrastructures and provision service caused a catastrophic water shortage in Yemen.
After the civil war began in 2015, the water buckets were destroyed significantly and price of water highly increased. Storing water has demolished by war and supply chains have been occupied by military personnel, which makes the delivery of water far more difficult. In 2015, over 15 million people need healthcare and over 20 million need clean water and sanitation.
The Yemen civil war also have impact on the agriculture and production of food. Agricultural production in the country has suffered substantially leaving Yemen to face the threat of famine. 90% of the food in Yemen is met by importation.
