Colombian crude production sank to a 20-month low of 935,000 barrels per day in April as guerilla attacks and community protests curbed output. Technicians from parastatal Ecopetrol were barred for over a month by indigenous protesters from repairing the Caño-Limon pipeline after it was damaged in a March 25 guerilla attack. Ecopetrol was forced to declare force majeure on at least 25 delivery contracts due to the stoppage. U'wa indigenous at Toledo municipality, Norte de Santander, agreed to lift their blockade May 1 after the Mines & Energy Ministry agreed to suspend  the nearby Magallanes gas exploration project to evaluate its environmental impacts and to despatch a team to demarcate the boundaries of U'wa territory. But the very next day, the pipeline was blown up again, at Cubará muncipality, Boyacá. The first attack was attributed to the FARC rebels, now in talks with the government. The second one was blamed on the ELN guerillas, which may be hoping to pressure the government to similarly open talks with them. There were 33 pipeline attacks in the first quarter of this year and a total of 259 in 2013. (UDW, May 28; El Tiempo, May 8; InfoSur Hoy, Bloomberg, May 6; EBR, May 5; Reuters, May 2)

A new report issued by Peruvian NGO Environmental and Natural Resrouces Law (DAR) counts 412 hydro-electric dams to be built across the Amazon basin and its headwaters if current plans go ahead, potentially leading to the "end of free-flowing rivers" and contributing to "ecosystem collapse." Of the 412 dams already in operation, under construction or proposed, 256 are in Brazil, 77 in Peru, 55 in Ecuador, 14 in Bolivia, six in Venezuela, two in Guyana, and one each in Colombia, French Guyana and Surinam, said anthropologist Paul Little at the launch of the English version of the report, "Mega-Development Projects in Amazonia: A Geopolitical and Socioenvironmental Primer." (PDF). The report finds: "This new wave of dam building in the headwaters of the Basin is a 'hydrological experiment' of continental proportions, yet little is known scientifically of pan-Amazonian hydrological dynamics, creating the risk of provoking irreversible changes in rivers."

An unknown number of miners—perhaps as many as 40—were buried alive as an illegal gold mine collapsed late on the night of April 30 at El Palmar, in Colombia's southern department of Cauca. Local campesinos spent May Day volunteering with Santander de Quilichao municipal brigades in a desperate effort to unearth the victims—none of whom are believed to survive. Thus far, only three bodies have been recovered, according to local Red Cross workers. Local residents said the "owners" of the mine were able to escape, but it is still unlcear exactly who they are.

Colombia campesinos launched a new national strike on April 28, blocking roads through the departments of Antioquia, Caldas, Tolima and Risaralda. Cesar Pachón, spokesman for campesinos in the central department of Boyacá, said the strike will continue indefinitely until the government of President Juan Manuel Santos helps resolve problems, include small farmers' debts of more than $1 billion. Pachón estimates that 100,000 have joined the strike so far. The decision to strike if the government did not respond by the end of April was taken during the Campesino, Ethnic, and Popular Agrarian Summit, held from March 15-17 in Bogotá.

The offices of the Cali Municipal Workers Synidicate (Sintraemcali), located in the center of the Colombian industrial city, was attacked with hurled incendiary bombs April 16, causing damage to the facade and plumbing of the building. Sintraemcali called the bombing a "terrorist attack," and pledged to file a complaint with the Inter-American Human Rights Commission. The attack came five days after a judge in Bogotá ordered the president of the republic, Juan Manuel Santos, to issue a formal pardon to members of Sintraemcali, the Colombian University Workers Syndicate (Sintraunicol) and the Bogotá Telecommunications Workers Synidate (Sintratelefonos), who had been accused by former president Álvaro Uribe Vélez of being linked to terrorist groups and constituting a "Brotherhood of Terrorism."

An official from the capital district government of Bogotá on March 28 called upon Colombia’s national government to open debate on broadening the policy of cannabis decriminalization. "We really need leadership from the Congress and the government to regulate the medicinal and recreational use of marijuana," said secretary general of the Bogotá mayor's office, Susana Muhamad. Despite efforts by the previous president Alvaro Uribe to roll back the policy, since 1994 cannabis has been decriminalized in small quantitites—recently established by the judiciary as up to 22 grams. However, sale and cultivation remain illegal. Muhamad appealed to current President Manuel Santos to examine lifting these limitations.

A Colombian activist for restitution of usurped lands who was supposedly under special government protection was killed April 9. Colombia's official human rights ombudsman said Jesús Adán Quinto—who had previously reported that agents assigned to protect him had failed to show up—was killed by sicarios (hitmen) as he stepped outisde his home at Turbo in Urabá region of Antioquia department. Quinto was a leader of the displaced population from Cacarica (Riosucio muncipality, Chocó department), a self-declared "peace community" where the Afro-Colombian campesinos have been massively targetted by paramilitary forces since announcing their non-cooperation with all armed actors in 1999. Quinto's fellow activist Carmen Palencia told AFP news service that the people now occupying the lands of the displaced are hiring assassins to terrorize those those who demand return of usurped properties. She said there have been 70 people associated the peace community killed in similar circumstances since 2005. The violence-torn region of Urabá straddles the north of Antioquia and Chocó departments.

Colombian President Juan Manuel Santos on April 4 told onlookers in the Pacific port of Buenaventura that 136 members of dangerous criminal gangs had been captured by security forces over the last month and a half, contributing to a recent drop in violence. Santos also told the crowd that the city had not seen a homicide for the last 19 days. Additionally, he said that 32 of the last 48 days had passed without a murder in Buenaventura. Santos also boasted of $100 million worth of investment in social programs for the city. This government has "decided to change the situation in Buenaventura and we are doing it with actions, not words," he said. But he added that the response to recent horrific violence in the city is not necessarily to "look for those responsible" but to find "solutions" to social problems.
