Manila, Beijing start compensation talks for Filipino fishermen

PHILSTAR

MANILA and Beijing will start talks next month for the compensation of Filipino fishermen who were on board a boat that was rammed, sunk, and abandoned by a Chinese fishing vessel in June 2019 at the West Philippine Sea, according to Justice Secretary Menardo I. Guevarra.

Mr. Guevarra told reporters on Monday that the matter was taken up by the governments of the Philippines and China during their “sixth consultative meeting” last Friday.

The Philippine panel on the compensation talks will be composed of officers of the Department of Justice (DoJ), Department of Foreign Affairs, and Department of Agriculture-Bureau of Fisheries and Aquatic Resources.

The Justice chief said they created the group “to put a close to this festering issue.”

“As far as the Filipino fishermen are concerned, it is important that they recover fully their expenses for the boat repair and the income they lost while the boat was under repair,” he said.

The DoJ’s assessment of damages due to the owners and crew of the fishing vessel F/B Gem-Ver amount to P12 million for repairs, loss of income, wages for six months, and moral damages. 

The Philippine government committed last year to help the Gem-Ver owners and crew, including 22 fishermen, claim compensation.   

The Chinese Yuemaobinyu 42212 vessel’s owner has so far only apologized for the incident. 

A Vietnamese vessel passing near the Recto Bank where the sea mishap took place rescued the Filipino fishermen.

Gem-Ver owners Felix and Fe Dela Torre reported spending about P2.1 million in Nov. 2019 to repair the boat.

Mr. Guevarra said the Philippine panel will meet with their Chinese counterparts on June 2 and 7 to discuss the compensation. — Bianca Angelica D. Añago

Anti-red tape agency to set up Matnog Port single processing shop

@COASTGUARDPH

THE ANTI-RED Tape Authority (ARTA) is planning to open a one-stop processing shop at the Matnog Port in Sorsogon by June after receiving complaints from motorists of congestion and under-the-table transactions to get loading priority.   

The Matnog Port in the southeastern tip of Luzon, ARTA said, is considered as a “funnel” to Mindanao. Most cargo being transported between Luzon and the Visayas and Mindanao pass through Matnog.

Cargo trucks are being asked to pay fees of up to P8,000 for a slot in a priority list to board roll-on, roll-off vessels faster, ARTA said in a press release on Tuesday. 

“The complainant further added that the actual fee is supposed to be more or less P3,000 only and that the amount in excess of the P3,000 goes to the fixers and corrupt officials,” ARTA said.

“The alleged fixers also reportedly ask passengers for money to buy coffee and snacks.”

Officials from at least two shipping lines also alleged that a local government task force has taken over the management of the port, which is under the Philippine Ports Authority. The officials complained that the local government intervention has complicated the flow of port operations, ARTA said.

ARTA Undersecretary Carlos F. Quita said local government units have no jurisdiction over port operations and cargo trucks should not be prevented from boarding vessels if they have the necessary permits.

Local governments charging banned fees on goods transportation may also be investigated under recent guidelines issued by ARTA and other government agencies.

The Philippine Ports Authority, the Philippine Coast Guard, and barge operators will be involved in creating the one-stop shop at Matnog. — Jenina P. Ibañez

Bill on overseas workers department hurdles Senate committees

DFA

SEVERAL Senate committees on Tuesday approved a measure that will create a department that will address concerns of migrant and overseas Filipino workers.

Senator Emmanuel Joel J. Villanueva, chair of the labor committee, endorsed to the plenary Senate Bill No. 2234 or the Department of Migrant Workers and Overseas Filipinos Act.

Other committees that approved the measure were foreign relations, civil service, government reorganization and professional regulation, and finance.

Under the bill, the Philippine Overseas Employment Administration will be constituted as the new department. Seven other agencies will be merged and transferred to the department.

Mr. Villanueva, in his sponsorship speech, said the creation of the new department “does not mean a shift to embracing labor export as a policy but plainly a shift to improve collaborative governance.”

The new department will have an estimated budget of around P1.1 billion, “consistent” with the Department of Budget and Management’s recommendations.

The House of Representatives approved in March 2020 the counterpart House Bill No. 5832.

The bill for the creation of a department for overseas Filipinos was identified by the Legislative-Executive Development Advisory Council as a priority measure targeted to be passed by Dec. 2021. — Vann Marlo M. Villegas

PLDT helps local farmers through digital projects 

SMART.COM.PH

PLDT, Inc. said it assisted local farmers increase their productivity and income amid the coronavirus disease 2019 (COVID-19) pandemic through three projects that used digital tools.

PLDT said in a statement on Tuesday that more than P2 million in revenues were generated from the sale of 36,000 kilograms of rice under its “#BuyLocal” campaign.   

The campaign benefitted almost 1,000 farmers and raised P180,000 for the “Buy Local” sustainability fund that will be used as capital for small-scale farmers.   

PLDT’s wireless unit Smart Communications, Inc. will distribute P100,000 from the sustainability fund to 20 farmer beneficiaries in Mindoro Occidental.   

The “#BuyLocal” campaign, in partnership with e-commerce platform Cropital, allows PLDT and Smart employees based in Metro Manila to purchase rice directly from small-scale farmers.   

“This helps provide sure markets for the farmers’ produce through employee purchases, thus increasing farmers’ source of income,” PLDT said.   

Meanwhile, PLDT said it also partnered with the Department of Agriculture-Agricultural Training Institute (DA-ATI) for the Digital Farmers Program (DFP) project.   

The project gives farmers access to digital tools and technologies that can help improve farm efficiency, productivity, and marketability.

Stephanie V. Orlino, Smart assistant vice president for community relations, said the basic DFP trainings help smallholder farmers who cannot use agriculture apps due to lack of digital knowledge.   

Smart also partnered with DA-ATI for an online information and awareness campaign that helps households and communities grow their own food.   

“Kalye Mabunga has become an avenue for recreation among families,” DA-ATI Information Services Division Chief Antonietta J. Arceo said.   

Hastings Holdings, Inc., a unit of PLDT Beneficial Trust Fund subsidiary MediaQuest Holdings, Inc., has a stake in BusinessWorld through the Philippine Star Group, which it controls. — Revin Mikhael D. Ochave   

P50-M Biliran bridge rehabilitation starts July   

DPWH

THE BRIDGE connecting the island province of Biliran to mainland Leyte in the central Philippines will undergo a P50-million restoration starting July,  the Department of Public Works and Highways (DPWH) announced.

DPWH Secretary Mark A. Villar, in a statement Tuesday, said the 150-meter bridge needs to be fortified as it can no longer accommodate large and heavy cargo vehicles.

“Apart from securing the safety and convenience of travelers and residents, we are also preserving the historical significance of the existing bridge,” he said.

The Biliran Bridge was inaugurated in 1976.

The Biliran provincial government says on its website that the development of what was then just a town under Leyte started with the construction of the bridge.    

DAR ordered to speed up land distribution to quell insurgency in Negros Oriental 

PRESIDENT Rodrigo R. Duterte has ordered the Department of Agrarian Reform (DAR) to hasten the distribution of government lands to beneficiaries in Negros Oriental in the central part of the Philippines in a bid to quell local insurgency, the Palace said on Tuesday.

Presidential Spokesman Herminio “Harry” L. Roque, Jr. made the statement a day after Mr. Duterte presided over a security meeting in the province, which is part of the Central Visayas Region that also includes Cebu, Bohol, and Siquijor.   

“In Negros province, land deprivation is one of the reasons why there is rebellion,” Mr. Roque, speaking in Filipino and citing the President, told a televised news briefing.

The province has a long history of violence triggered by issues of lands rights, poverty, and injustice, according to international group Human Rights Watch.   

In July last year, at least 20 people were killed in the province in a string of shooting incidents. Both government forces and communist rebels were implicated in the killings.

Mr. Duterte in 2019 ordered DAR officials to finish the distribution of lands under the Comprehensive Agrarian Reform Program, which was initiated in 1987 by the late President Corazon “Cory” C. Aquino. — Kyle Aristophere T. Atienza

TASK FORCE BANGON MARAWI FB PAGE

THE NATIONAL task force handling the restoration of war-ravaged Marawi City in the southern Philippines said reconstruction of public infrastructure is now 65% complete and on track for completion before President Rodrigo R. Duterte steps down in 2022.

“Since we started with the vertical and horizontal infrastructure for the rehabilitation of Marawi City last year, it is now 65% complete,” Secretary Eduardo D. del Rosario, chair of Task Force Bangon Marawi, told a televised news briefing in a mix of English and Filipino.

Mr. Del Rosario, who also serves as the country’s housing minister, added: “We are on track with our stated deadline of December of the year that 100% of all our ongoing projects will be completed.”

Mr. Del Rosario last year told lawmakers that the state had already released about P22 billion for the rebuilding of the city, which was left in ruins after a five-month clash between government troops and Daesh-inspired local extremists that began on May 23, 2017.

Presidential Spokesman Herminio “Harry” L. Roque, Jr. said national officials would visit Marawi by next month to check on the status of the beleaguered city.

Over the weekend, various local civil society groups lambasted the government for its failure to address the needs of displaced residents. — Kyle Aristophere T. Atienza

Tarlac City’s task force quarry head arrested for alleged extortion

THE HEAD of Tarlac City’s task force on quarrying was arrested on Monday for alleged extortion activities reported by a quarry clearance applicant.

The Anti Red Tape Authority (ARTA) said Tarlac City task force quarry head Pedro Soliman II was arrested after the agency received a complaint from an applicant who was asked to pay P240,000 for a clearance.

“The complainant said she recently went to the Tarlac City Hall to pay a fee of P42,000 for booklets of delivery receipts, a requirement for operating a quarrying firm,” ARTA said in a press release on Monday.

“She was then asked by Soliman to pay P10,000 per finished booklet or a total of P240,000 in exchange for her Tarlac City quarry clearance.”

Mr. Soliman was arrested by a team composed of representatives from ARTA, the police’s Criminal Investigation and Detection Group, and Tarlac City Police after he accepted entrapment money poised as an initial P80,000 payment from the complainant.

He may face charges for violating Republic Act 11032 or the Ease of Doing Business and Efficient Government Service Delivery Act of 2018 and the circular banning fees on the transport of goods.

ARTA is investigating local government units that continue to charge transport fees on goods despite the circular banning the practice. — Jenina P. Ibañez

Duterte signs order improving gov’t humanitarian response operations

PCOO.GOV.PH

PRESIDENT Rodrigo R. Duterte has signed an order to accelerate and harmonize the national government’s humanitarian response and social service operations during disasters and emergencies.

Under Executive Order No. 137, signed on May 24, the President institutionalized the so-called Aid and Humanitarian Operations Nationwide (AHON) Convergence Program, a platform “for an enhanced and unified delivery of social amelioration services.”

The order also creates the AHON Committee, to be chaired by the Office of the Special Assistant to the President and co-chaired by the Department of Social Welfare and Development (DSWD).

Its composition includes representatives from the following departments: Trade and Industry, Agriculture, Health, Information and Communications Technology (ICT), Labor and Employment. It also includes the Philippine Charity Sweepstakes Office.

“Nothing in this order shall be construed to prevent any national government agency or LGU (local government unit) from affording assistance and taking such other action in the event of any emergency or disaster prior to the inclusion of such intervention to the AHON Convergence Program,” the order read.

The order also mandates the National Economic and Development Authority and the ICT department to establish and maintain a unified Convergence Information System, which shall contain “a database of verified individuals, families, communities, cities, municipalities, and provinces who have benefitted from the AHON Convergence Program subject to the provisions of the Data Privacy Act of 2012.”

The system shall utilize geotagging tools and other appropriate technologies recommended by the Department of ICT, it said.

“All departments, bureaus, agencies, offices, and LGUs, including government-owned or controlled corporations, as well as government financial institutions, and state universities and colleges, are encouraged to render full support and cooperation to the Committee in carrying out its mandate.” — Kyle Aristophere T.

Saving capitalism from profit obsession

JANNOON028-FREEPIK

(Part 5)

We have seen some specific examples of how business enterprises that started with modest offerings of goods or services to a limited clientele eventually evolved into large corporations that have succeeded in articulating corporate purpose in an effective way for better governance and management. We saw how Ikea, the biggest furniture company in the world, transformed itself from a mail-order business that sold pencils, postcards, and similar merchandise into a multinational enterprise with a clear corporate purpose. We also observed how large Philippine conglomerates like San Miguel Corp., Ayala Corp., and the DMCI Corp. have evolved into purpose-driven businesses with the active participation of their respective boards of directors and top management.

As an addendum, we can also refer to another business case cited by Dr. Jordi Canals* which is that of British-Dutch multinational corporation Unilever that is very active in our own domestic market. Also with humble beginnings, Unilever has its roots in two Dutch companies founded by Van den Ber and Jurgens, two Dutch entrepreneurs and butter merchants who diversified into margarine, a new butter alternative; and in a British company set up by William Lever, a British entrepreneur who started to make an inexpensive household soap in the late 1880s. By the end of 2016, Unilever owned more than 400 brands in close to 200 countries, with a total revenue of 2.7 billion euros. Through the leadership of Paul Polman who became Unilever’s CEO in January 2009, the corporation adopted an ambitious approach to combining business performance with wider social impact, with its Unilever Sustainable Living Plan (USLP). This was a radical management innovation that included the firm’s social impact as a central element of its corporate strategy. This plan was also the main pillar in making Unilever a multi-stakeholder company, a concept in which Unilever was a pioneer and a leader.

Using the experiences of Ingka and Unilever, Dr. Canals provides some guidelines to boards of directors and senior managers on how to unbundle the notion of corporate purpose and its use. The first step is to identify a very specific challenge that the company aims to tackle, and the type of need or problem that it wants to solve. A good purpose needs to include both a goal that engages people along with dimensions that require a business solution. Without a challenge, a purpose may lose its drive. That challenge may not have a very high aspirational goal, but has to be related to other people’s needs. It may include special customer demands that need to be addressed, some unresolved concerns that current customers have, the aspiration to make the consumers’ efforts to buy from that company less costly (including lower prices), or the ambition to reduce the environmental impact of the firm’s operations.

The experience of companies that have been doing a good job in defining purpose suggests that the most difficult part of purpose is its translation into strategy and the business model. The real challenge is clarity in purpose and its implementation through different policies. Specifically, an answer to some key questions is very relevant: what purpose concretely means for individuals in this company; how individuals’ sense of meaning is strengthened; how the firm’s strategic goals are defined and how coherent they are with purpose; how the activities and policies that define the business model are shaped by purpose; how goals are measured; how the organization is structured; and how measurements and rewards systems are defined and influenced by corporate purpose. Monitoring goals and reporting systems are particularly important for companies that define a corporate purpose. If a company continues to measure performance with the same economic indicators as it did before the definition of purpose, or the priority continues to be short-term economic performance, the impact of purpose will be limited. If purpose helps top management redefine goals and establish indicators that can truly reflect how the company is doing regarding purpose, it will help align strategy and people’s behavior around what its purpose expresses.

As with other functions of the board of directors, working on purpose is primarily the work of the CEO and the management team. The board should help the CEO by reviewing purpose and making sure that it is a comprehensive and actionable project, connected with corporate strategy and corporate culture, and that it influences hiring and developing people. The board may add some areas of expertise and evidence, and give advice on how its principles and metrics can be shared effectively with shareholders and other stakeholders. Communication with the investor community in this regard is not only the responsibility of the CEO or the CFO. The board should take this responsibility seriously and act accordingly. Purpose offers a wider perspective of the role of boards of directors and the duties of board directors. In the end, it gives boards of directors a unifying and useful sense of long-term direction that can be shared by the whole company.

Framing a discussion around purpose would require a skillful preparation by the chairman and the CEO to put the right questions and challenges in front of the board, and prepare useful information to be studied before the board meeting. Some specific questions that may help improve the quality of the debate, and place this debate in the context of what is expected from a board of directors in this area are as follows:

• Do the board of directors understand the firm’s purpose and its implications for governance and management?

• What specific customer need is this company serving? What role do customers play in the management of the firm?

• Why would talented people want to work in this company?

• Why do investors want to invest in this firm? Which time horizon do they have?

• What is the overall impact of purpose?

The quality and strength of a company’s purpose lie not so much in their level of aspiration, but in the way that they connect with strategy, strategic plans and decisions as well as implementation. Strategy is a very important area of responsibility for the board of directors, to be shared with the CEO and top management team. A positive impact of corporate purpose is how it nurtures and improves the quality of strategy discussions. For this reason, the board should look at corporate purpose as a very important pillar for formulating and executing strategy. For example, in the case of Unilever, the CEO and the management team designed the firm’s sustainability plan in such a way that it became fully integrated with its strategy and business model, including product design, sourcing, operations, logistics, manufacturing, and distribution. Their main goal was that the Unilever Sustainable Living Plan should cover the firm’s whole supply chain and not outsource the responsibility for sustainability and environmental impact to third parties through outsourcing programs. To connect strategy with purpose, the following questions can be helpful:

• How is strategy linked with corporate purpose?

• Does the business model reflect the firm’s purpose?

• Does a strategic decision reinforce the sense of purpose?

• How does a strategic decision change the risk profile of an organization?

It is important to assess the overall impact of purpose. Measuring some indicators of purpose has become indispensable for boards of directors and CEOs in their communication with shareholders and other stakeholders. Each company needs to develop its own reporting model. It will depend on the nature of each firm and the definition of purpose that the company adopts. In many cases, corporate purpose will include the well-being of customers and employs, some environmental and social goals and some financial indicators. ESG factors may also be included, although they do not capture the entire purpose of many firms. Investors and corporate leaders increasingly understand that companies have a role to play in social challenges such as climate change or the reduction of mass poverty.

A company with a purpose and that takes culture seriously must hire professionals who have a good fit with the firm. Cultural fit is a requirement in recruitment, especially in the case of hiring managers since they are the ones who coordinate people’s work, engage people, and eventually are the ones responsible for professional development of the workforce. Professional competence is indispensable, but cultural fit is critical for companies with a clear purpose. The board has a special responsibility in the CEO appointment. If the board truly believe that purpose is a special dimension of the company, board members should also ask themselves how to assess the candidates’ capacity to absorb the firm’s purpose, renew it, and translate it into strategy, strategic decisions, and the firm’s operations, as well as how to make the firm’s business model sustainable. Finally, it is also the responsibility of the board of directors to find the best long-term shareholders for the company. The current firm’s shareholders may not be in the firm in the future. Investors may change their minds and do not have many constraints that prevent them from selling their shares. Successful companies have the support of the right type of shareholders.

Unfulfilled promises

MASTER1305-FREEPIK

Months into his presidency in 2016, President Rodrigo Duterte announced a foreign policy pivot to Beijing, as he shored up to $24 billion (P1.2 trillion) in funding pledges from China.

The initial list consisted of 26 big-ticket projects and was supposedly a display of greater confidence in the bilateral relations between Manila and Beijing.

This included: 1.) the Subic-Clark railway project by the Bases Conversion and Development Authority (BCDA) and China Harbour Engineering Co., 2.) the Bonifacio Global City-Ninoy Aquino International Airport Segment of the Metro Manila Bus Rapid Transit-EDSA project by the BCDA and China Road and Bridge Corp., 3.) Safe and smart city projects for the BCDA by the BCDA and Huawei Technologies, and, 4.) Transportation and logistics infrastructure at Sangley Point by Cavitex Holdings, International Container Terminal Services, Inc., and China Harbour Engineering, among others, most of which have never materialized into actual infrastructure in five years of Mr. Duterte’s term.

These projects were envisioned as part of China’s Belt and Road Initiative (BRI), which was built as a global investment and economic growth program. By early 2021, 140 countries worldwide had signed more than 200 BRI cooperation agreements — essentially frameworks for Chinese companies to build infrastructure projects such as ports, railways, power stations, and telecommunication networks using low-interest Chinese loans to host countries.

However, the pivot has not benefited the country as touted in 2016. Less than 5% of China’s promised $24 billion in loans and investments have come to fruition. Also, only a few China-funded projects have been completed or are set to be completed in 2021, such as the Binondo-Intramuros Bridge and the Estrella-Pantaleon Bridge, both of which had been hounded by controversies relating to the use of Chinese construction workers instead of Filipinos.

In fact, one major project funded through Official Development Assistance (ODA) — the P12.2-billion Kaliwa Dam project — remains in the early stages of implementation, with continuing objections from indigenous groups and local governments.

While there is a new China-financed bridge project connecting Samal Island and Davao City, it has been noted that other prospective China-financed projects were now going to be funded by other foreign sources, such as the Panay-Guimaras-Negros Bridge, which is aimed at improving the transport of agricultural goods in the region.

Aggravating the current situation has certainly been the coronavirus crisis, which has delayed many projects in the infrastructure sector. No less than the National Economic Development Authority (NEDA) said, “The unprecedented challenges brought by the COVID-19 pandemic, however, is expected to alter the overall infrastructure development agenda. The resource requirements of the response to the pandemic are expected to reduce the fiscal space initially allotted for the portfolio of investments and could slow down the movement and implementation of programs and projects.”

While the NEDA views using the Build, Build, Build (BBB) program as an instrument for socioeconomic recovery, the government should acknowledge that direct pandemic responses, such as vaccine procurement, massive testing, and social subsidies, should now take precedence in the national budget instead of expediting the implementation of still-indicative infrastructure projects.

The role of the BBB program in socioeconomic recovery should be confined mainly to projects already being implemented, or those with Notices-to-Proceed within the next six months, as still-indicative projects should not compete anymore with coronavirus response appropriations within our tightening fiscal space.

With this development, it is also time to rethink our pivot to China and assess whether it has been truly beneficial in resolving infrastructure underdevelopment in the last five years.

Despite the high-level projections of no less than the President on the impact of our bilateral relations, Japan remains the Philippines’ top provider of ODA, with the bulk of funding going into the BBB.

Japan has provided ODA amounting to $11.2 billion, while China only provided $600 million, a distant fifth from the list of other ODA funders such as the Asian Development Bank ($8.5 billion), World Bank ($5.3 billion), and South Korea $700 million).

Tokyo’s funding commitment is 18 times more than Beijing’s. This number should give the government pause on which bilateral partner truly cares for the nation’s development.

For all the President’s pro-China posturing, Beijing’s funding commitment just approximates the level of funding of local infrastructure projects proposed by legislators every year. In other words, the country is receiving pennies for all the chest-thumping that it has been doing in support of closer ties with Beijing.

And for what? The Palace continues to belabor the point on the current legal status of the waters, reefs, and islands within the West Philippine Sea.

It has employed doublespeak on the status of Julian Felipe reef, arguing that it was no less than the Hague ruling that invalidated the Philippine claim over the reef, only to capitulate over our legitimate claims over the area.

Despite Beijing’s failure to deliver on its development commitments, Malacañang continues to speciously tout China as the nation’s savior, showing no recalibration from the posture taken at the beginning of its term.

But it should be warned that we are now less than a year away from the elections, and most certainly, the skewed bilateral relations with Beijing will continue to hound this administration in the days leading to the elections.

It should remember that nothing lasts forever, even for those with the “mandates of heaven.”

Fly infertility shows we’re underestimating how badly climate change harms animals

MACROVECTOR-FREEPIK

Evidence of declining fertility in humans and wildlife is growing. While chemicals in our environment have been identified as a major cause, our new research shows there’s another looming threat to animal fertility: climate change.

We know animals can die when temperatures rise to extremes they cannot endure. However, our research suggests males of some species can become infertile even at less extreme temperatures.

This means the distribution of species may be limited by the temperatures at which they can reproduce, rather than the temperatures at which they can survive.

These findings are important, because they mean we may be underestimating the impacts of climate change on animals — and failing to identify the species most likely to become extinct.

Researchers have known for some time that animal fertility is sensitive to heat stress.

For example, research shows a 2°C temperature rise dramatically reduces the production of sperm bundles and egg size in corals. And in many beetle and bee species, fertilization success drops sharply at high temperatures.

High temperatures have also been shown to affect fertilization or sperm count in cows, pigs, fish and birds.

However, temperatures that cause infertility have not been incorporated into predictions about how climate change will affect biodiversity. Our research aims to address this.

The paper published today involved researchers from the United Kingdom, Sweden and Australia, including one author of this article. The study examined 43 species of fly to test whether male fertility temperatures were a better predictor of global fly distributions than the temperatures at which the adult fly dies — also known as their “survival limit.”

The researchers exposed flies to four hours of heat stress at temperatures ranging from benign to lethal. From this data they estimated both the temperature that is lethal to 80% of individuals and the temperature at which 80% of surviving males become infertile.

They found 11 of 43 species experienced an 80% loss in fertility at cooler-than-lethal temperatures immediately following heat stress. Rather than fertility recovering over time, the impact of high temperatures was more pronounced seven days after exposure to heat stress. Using this delayed measure, 44% of species (19 out of 43) showed fertility loss at cooler-than-lethal temperatures.

The researchers then matched these findings to real-world data on the flies’ distribution, and estimated the average maximum air temperatures the species are likely to encounter in the wild. They found the distribution of fly species is linked more closely to the effects of high temperature on male fertility than on temperatures that kill flies.

These fertility responses are crucial to species survival. A separate study led by one author of this article, using simulated climate change in the laboratory, showed experimental populations of the same flies become extinct not because they can’t survive the heat, but because the males become infertile. Species from tropical rainforests were the first to succumb to extinction.

The prediction that tropical and sub-tropical species may be more vulnerable to climate change is not new. But the fertility findings suggest the negative impact of climate change may be even worse than anticipated.

Some animals have adapted to minimize the effect of high temperature on fertility. For instance, it’s thought testes in male primates and humans are externally located to protect the developing sperm from excessive heat.

As the planet warms, animals may further evolve to withstand the effects of heat on fertility. But the speed at which a species can adapt may be too slow to ensure their survival. Our research has shown both tropical and widespread species of flies could not increase their fertility when exposed to simulated global warming, even after 25 generations.

A study involving beetles also indicates fertility damage from successive heatwaves can accumulate over time. And more work is needed to determine how other stressors such as salinity, chemicals and poor nutrition may compound the fertility-temperature problem.

Whether our findings extrapolate to other species, including mammals such as humans, is not yet clear. It’s certainly possible, given evidence across the animal kingdom that fertility is sensitive to heat stress.

Either way, unless global warming is radically curbed, animal fertility will likely decline. This means Earth may be heading for far more species extinctions than previously anticipated.
