Close to 80,000 people have been displaced in Tambura County, in South Sudan's Western Equatoria, as a result of fighting between government forces and the opposition SPLA-IO–even though both sides are supposed to be forming a new unified army. A delay to security sector reform continues to set back implementation of a 2018 peace agreement. The Pretoria-based Institute of Security Studies has warned that South Sudan's "militarized political culture" could see tensions "boiling over"—threatening the national unity government. Faction fighting within SPLA-IO has added to the insecurity. Meanwhile, the World Food Programme is suspending aid to more than 100,000 displaced people in Wau, Juba, and Bor beginning in October—part of a three-month "prioritization exercise" driven by a finance crunch. The fall in funding is despite the country experiencing the highest rate of food insecurity since independence in 2011, with more than 60% of South Sudanese going hungry. Months of flooding has added to that toll.

A record number of environmental defenders were murdered last year, according to a report issued this week by advocacy group Global Witness. The report, "Last Line of Defense," counts 227 activists killed around the world in 2020—the highest number recorded for a second consecutive year. Many of the murders were linked to resource exploitation—logging, mining, agribusiness, and hydroelectric dams. Since the 2015 Paris Agreement on climate change, the organization found on average of four activists have been killed each week.

Denmark and Costa Rica jointly announced that they are launching an alliance of nations committed to setting a firm date to completely phase out use and production of fossil fuels. The two countries hope to present the initiative, tentatively dubbed the Beyond Oil & Gas Alliance (BOGA), at the upcoming UN climate summit in Glasgow, Scotland. Nearly 60 countries have made some sort of net zero emissions pledge, but only a handful of those have actually set a target in law or enacted bans on new fossil fuel exploration and production. An International Energy Agency report released earlier this year found that new fossil fuel exploration needs to halt by 2022 in order to keep warming within the limits set by the 2015 Paris Agreement. "We are in a paradoxical situation right now where many countries have pledged to become carbon neutral but are actually still planning to produce oil and gas after that date," Danish Minister of Climate & Energy Dan Jorgensen told Reuters.

At least 90 people have been killed in wildfires that have swept through northern Algeria over the past weeks. The blazes have consumed some 100,000 acres, mostly in the northeastern Kabylia region and its central province of Tizi Ouzou. While remaining silent on the role of climate change, the Algerian government seems to be exploiting the disaster for political purposes. President Abdelmadjid Tebboune on Aug. 18 said most of the fires were "criminal" in origin, and blamed them on regional rival Morocco. The two countries were already in a diplomatic tiff before the new accusations. "The incessant hostile acts carried out by Morocco against Algeria have necessitated the review of relations between the two countries," the presidency said in a statement, adding that there will be an "intensification of security controls on the western borders." Algeria's western border with Morocco has already been sealed and heavily militarized since 1994.

More than 500,000 people are in need of emergency assistance in Haiti's southern peninsula, where last week's 7.2-magnitude earthquake has killed more than 2,100 people and injured more than 12,200. Aid and medical efforts are hampered by debris-strewn roads, rain from Tropical Storm Grace, a shortage of working hospitals, and gang violence. The private Bernard Mevs Hospital in the capital, Port-au-Prince, where some of the injured have been sent, was closed Aug. 19 as part of a two-day shutdown to protest the kidnapping of two doctors. In recent years, Haiti has been beset by violent gangs who patrol many of the country's transport routes. Some villagers were also reportedly blocking aid shipments, saying they were also desperate for help. The southern peninsula has yet to recover from Hurricane Matthew, which killed at least 546 people in 2016. Prime Minister Ariel Henry has promised to speed up aid efforts—more than 30,000 families have been displaced, and there are fears of cholera due to lack of safe water, sanitation, and shelter. The United States has deployed several helicopters, aircraft, and the USS Arlington to help with relief efforts. France also sent a ship with humanitarian cargo, a helicopter, and more than two dozen soldiers.

Nigerian authorities imposed a curfew in Jos, capital of north-central Plateau state, after at least 20 Muslim travelers passing through the city were massacred by a presumed Christian militia Aug. 14. The Muslims, mostly of the Fulani ethnicity, were in a convoy of vehicles, returning to their homes in Ondo and Ekiti states from a celebration in neighboring Bauchi state marking the start of Muharram, the Islamic new year. In Jos, the convoy was caught in a traffic jam, and the vehicles set upon by militiamen—the occupants slain with machetes, daggers and other weapons. The assailants were apparently Christians of the Irigwe ethnicity. Northern and central Nigeria have for years seen growing violence between Muslim semi-nomadic herders and Christian farmers over control of land and water.

Climate change is "unequivocal" and rapidly intensifying, and some of the changes already in motion—such as continued sea level rise—are irreversible over hundreds to thousands of years, finds the latest report from the Intergovernmental Panel on Climate Change (IPCC), released Aug. 9. The IPCC Working Group I report, "Climate Change 2021: the Physical Science Basis," was approved by 195 member governments of the IPCC, having been prepared by 234 scientists from 66 countries. The report concludes that human influence has warmed the planet at a rate that is unprecedented in at least the last 2,000 years. Human-induced climate change is already affecting many weather and climate extremes in every region across the globe—including heatwaves, droughts, and tropical cyclones.

Children in Raqqa, northeast Syria, are still living among ruins, with limited water, electricity, and access to education, four years after the city was taken from ISIS, according to a new report by Save the Children. Thousands of people have returned to Raqqa since the battle for the city ended in 2017, and the report estimates that up tp 330,000 people are currently living there. But levels of rebuilding and rehabilitation of housing remain low, with children living in constant fear of their homes collapsing on top of them. Research estimates that 36% of the city's buildings remain entirely destroyed.
