Researchers from the Indian Institute of Technology Madras, in collaboration with Harvard University have developed a novel Machine-Learning algorithm named 'CombSGPO' (Combined Security Game Policy Optimization) to help save the wildlife from poaching.
IIT Madras, in a statement, said that the researchers have found that combined and coordinated use of the Forest Rangers and drones were a good way to protect wildlife from poaching.
"As the resources (Rangers and drones) are limited, the researchers developed this algorithm which provides a good strategy to protect wildlife with the resources available. This new algorithm provides highly efficient strategies that are more scalable than the earlier ones created for the same purpose," the institute said.
The algorithm, as per IIT-M, works by handling resource allocation and strategizing patrolling after the extent of resources available had been identified. For this task, the algorithm utilizes data on the animal population in the conserved area and assumes that poachers are aware of the patrolling being done at various sites.
Prof Balaraman Ravindran, Mindtree Faculty Fellow and Professor, Department of Computer Science and Engineering, IIT Madras, and the Head of Robert Bosch Centre for Data Science and Artificial Intelligence (RBCDSAI), IIT Madras, collaborated with Professor Milind Tambe's Research Group - Teamcore - at Harvard University, US, to carry out this study.
Highlighting the need for such Research, Ravindran said that the work was motivated by the need to perform strategic resource allocation and patrolling in green security domains to prevent illegal activities such as wildlife poaching, illegal logging and illegal fishing.
"The resources we consider are human patrollers (forest rangers) and surveillance drones, which have object detectors mounted on them for animals and poachers and can perform strategic signalling and communicate with each other as well as the human patrollers," he added.
This developed algorithm utilizes a Game Theory-based model created by the researchers.
As per the World Wide Fund for Nature (WWF), the wildlife trade poses the second-biggest direct threat to the survival of species after habitat destruction.
While several organizations and regulatory authorities are trying to curb the incidences of poaching, the poachers seem to have always remained one step ahead of the patrollers. This collaborative research work by two esteemed universities will help in keeping poaching incidents in check.

5 Chinese workers killed in bombing
A convoy of Chinese engineers was targeted by an attacker driving an explosive-laden vehicle, according to local authorities of Pakistan.
Authorities in Pakistan said on Tuesday that five Chinese nationals were among six people killed in a suicide attack in the northwestern Khyber Pakhtunkhwa province.
Regional police chief Mohammad Ali Gandapur said a convoy carrying Chinese engineers was targeted by a suicide bomber who rammed an explosive-laden vehicle into them.
"Five Chinese nationals and their Pakistani driver were killed in the attack," Gandapur told news agencies.
What we know about the attack
The senior police official said the victims had been traveling from Islamabad to their camp in Dasu in the Khyber Pakhtunkhwa province — which is the site of the Dasu hydroelectric dam, currently being constructed by the China Gezhouba Group Company.
The attack took place along a winding, mountainous road that runs alongside a deep ravine.
Previously in 2021, a bus transporting engineers to the same site was targeted in an attack that killed 13 people, including nine Chinese nationals.
China has invested heavily into Pakistan's infrastructure over the past few years as part of the .
The Chinese projects have led to a level of resentment in some local quarters, with separatist groups claiming those from the region benefit little, with most jobs going to outsiders.
No group has claimed responsibility for the attack, but Islamist militants linked to the Pakistani Taliban have previously targeted Chinese interests in Pakistan.
Japan's yen dips to 34-year low against US dollar
The Japanese yen has hit its lowest level against the dollar in decades, even after Japan's central bank announced a hike in interest rates.
Currency markets saw Japan's yen dip to its lowest point against the dollar in more than three decades on Wednesday.
The fall has raised speculation that authorities might intervene in market trading to prop up the currency.
What's happening with the yen?
The yen fell to 151.97 against the dollar — the lowest point since 1990 — before rallying slightly. The dollar was last down at 151.19.
In the past two years, the yen has weakened significantly from roughly 115 against the dollar before Russia's invasion of Ukraine.
In a historic shift in monetary policy, Japan increased interest rates this month for the first time since 2007. However, this has done little to stablize the falling price of the yen, given that Japan's benchmark interest rates remain among the lowest in the developed world and are not expected to rise much further.
A weaker yen makes exports from Japan cheaper. However, it also drives up import costs and energy prices for consumers in the world's fourth-largest economy.
In a sign of concern about the need to shore up the currency, the Bank of Japan, the Finance Ministry, and Japan's Financial Services Agency held a meeting late in Tokyo trading hours.
Japanese Finance Minister Shunichi Suzuki said earlier that authorities could adopt "decisive steps" against yen weakness.
Bankrupt banks and higher interest: Are startups in crisis?
"Now we are watching market moves with a high sense of urgency," he told reporters.
The government could intervene directly in the currency market, buying large amounts of yen and usually selling dollars for the Japanese currency. Tokyo last took such action in 2022 when the yen was also floundering.
Why is the yen so low?
Japan last week raised interest rates for the first time since 2007 in a move that marked a historic shift in monetary policy.
Despite the rise in interest rates from negative territory, the cost of borrowing in Japan remains very low at 0 to 0.1%.
For investors, the US — which adopted an aggressive policy of hiking rates to tamp down inflation — offers a far more attractive rate of 5.25 to 5.5%, with a cut not priced in until July.
The value of the Japanese yen has already fallen more than 7% this year against the dollar.
Meanwhile, the dollar is on track for solid quarterly gains after investors tempered their expectations of big interest rate cuts in light of strong economic data and the reluctance from central bankers.
Decoding China’s Neo-Colonist practices in Africa
China’s interest in the African continent has been decades in the making. The Asian giant’s increased economic activities in African countries have raised significant concerns about the nature of its engagements in the continent, with many analysts and civil society groups drawing attention to worrying trends in China’s engagements in the continent.
These concerns stem from Beijing’s tendencies of deploying neo-colonist measures such as self-interested economic engagements spanning from high-interest loan lending for development projects to one-sided trade activities among others. With China becoming Africa’s largest trading partner and with trade volumes reaching billions of dollars annually, the concerns raised by civil society groups are attempting to signal towards the onset of a larger China problem in the continent.
The ‘China problem’ throughout Africa
Beijing has over the years become the largest bilateral creditor to African countries by providing financial loans for developmental projects to over thirty African countries including Angola, Ethiopia, Kenya, Djibouti, Cameroon, Zambia and Republic of Congo amongst many others in recent years. These financial loans have led to the continent owing Chinese creditors over $93 billion dollars up until 2022 and is expected to reach an all-time high figure of around $153 billion in the upcoming years.
Moreover, in its expansionist quest, Beijing has also overtaken major financial institutions such as the World Bank, the IMF and other traditional creditors all together and is the world’s largest official creditor currently. The Asian giant also has an outstanding claim of more than 5% of the globe’s total GDP and more than a dozen under-developed and developing countries own finances of at least 20% of their GDPs to China.
Under the pretext of developmental projects, China has masqueraded their economic assistance to nations that have been financially volatile due to various reasons. For instance, countries like Zambia, Congo, Ethiopia, Kenya amongst others have been pushed in to economic crisis more so due to high interested loans that have been granted by China’s developmental banks. The practice of ‘hidden debts’ in loan agreements has also caused major setbacks to volatile economies in Africa.
The BRI project alone has caused lower and middle-income countries with hidden debts amounting to around $385 billion until 2020 and is expected to far exceed the figure in the coming years. The Chinese side on its part has gone on record to demand for strict discretion on details of MoU’s that have been signed. This has subsequently left very little room for manoeuvring for these volatile economies in the continent subjecting them to be left at the behest of Chinese authorities.
The case of Kenya and Zambia as reminders for the African continent
In 2022, protests broke out in Kenya due to the economic turmoil caused by the high indebtedness to Chinese lenders, with protesters calling for greater transparency in contract details of MoU’s signed with Chinese authorities over the period of five years. Up until last year, Beijing-based companies as well as the Chinese government amounted for around a third of Kenya’s debt overall debt.
The protests in the African country forced the government to release partial details of the loan agreements which brought out the true imperialistic tendencies showcased by Chinese firms as well as the government. According to the contract details released by Kenya’s Transport department the details pertained to one of Kenya’s most ambitious projects taken under China’s behest – The Standard Guage Railway initiative. The project during its inception was agreed to be paid by the Exim Bank of China, in addition to the loans granted by the Exim Bank.
The Kenyan government had previously declared in 2020, that it had financial dues amounting to over 38 billion shillings to Afristar, a Chinese owned firm for the same project. This took the overall borrowing for the railway project above and over to 420 billion shillings from China.
In the released details it was also revealed that the Kenyan government was bound by the terms of the contract to keep the details secretive even though unfavourable terms had been agreed upon in the MoU. Until the details were made public, observers noted that Chinese contracts with developing countries usually included clauses in which borrower countries were mandated to prioritize repayments to Chinese state-owned firms over its other borrowings.
The contract details also stated that the SGR deal was a twenty-year-old loan with a seven-year grace period, in which Kenya was to repay within 13 years. Within this, at least 42% of the revenue generated from the project was to be used for repayment of the loans leading to the Kenyan government receiving no monetary benefit for a period of at least twenty years up until the Chinese loans were paid off.
The Zambian government too, faced a similar situation leading to political upheaval in the country due to excessive Chinese borrowings. The southern African country has currently sustained excessive debts most of which have been provided by Chinese developmental banks for white elephant projects that has generated under-performing revenues as compared to the cost of construction induced within them.
These excessive loans have now led to the Zambian government pleading its creditors for financial restructuring in debt agreements. Moreover, this had also led to the government cancelling around $1.6 billion worth of undisbursed loans form Chinese lenders causing a further halt to infrastructural projects across the country. Ironically however, China has refused to restructure debt repayments and has on the contrary secured itself guarantees from the Zambian government mandating the country to disburse its repayments first.
These preconditions have also hampered Zambia’s efforts in securing debt relief from its other creditors who have accused Beijing of sabotaging Zambia’s volatile economy in lieu for its own guarantees.
These examples serve as an important reminder to China’s sinister tendencies of colonizing the African continent through neo-imperialistic means. Under the pretext of development, Beijing has deployed all possible colonizing strategies to influence economic outcomes in different countries in the continent with many such countries now having to focus on repayments to China instead of crafting strategies for economic revival.
In light of such detrimental Chinese practices, it far more important and of urgency that other countries learn from the examples of despair faced by its fellow African nations before China comes knocking with excessive financial resources on their own doorsteps.
Hence a collective strategy must be undertaken by all African countries that see themselves under Chinese debt, for they may be Beijing next target.

Jacob Zuma barred from running in election
The former president has been expelled from the ruling ANC and has been campaigning for the newly formed MK party. An MK spokesman said the party will appeal the decision made by the Independent Electoral Commission.
Former South African President Jacob Zuma has been disqualified from running in the country's general elections in May.
The Independent Electoral Commission (IEC) said on Thursday he was one of eight candidates who faced official objections.
"In the case of former president Zuma, yes, we did receive an objection, which has been upheld," IEC chairperson Mosotho Moepya said at a media briefing.
The IEC disqualified him over his 2021 conviction and jailing for contempt of court.
Increasing tensions in the run-up to the polls
Zuma, who led the country from 2009 to 2018 until his removal amid wide-ranging allegations of corruption, parted ways with the ruling African National Congress in December and is now leading the newly formed uMkhonto weSizwe Party (MK).
MK spokesman Nhlamulo Ndlhela told the AFP news agency the party " of course will appeal" the IEC's decision.
Some of the party's leaders have previously threatened violence if Zuma was barred from contesting the elections.
Seperately the ANC has launched a legal challenge against Zuma's party, disputing its use of the name and trademark of the dissolved organization.
The MK party is named after the former military wing of the ANC, which was disbanded at the end of apartheid.
MK party can still compete in the vote
The IEC's decision does not prevent the MK party from taking part in the May 29 poll.
It is widely expected to be the most competitive vote since the advent of democracy in South Africa in 1994.
According to recent polls, the ANC may dip below 50% of the national vote for the first time since it came into power.
Zuma's popularity has helped the MK Party gain traction ahead of the upcoming polls, particularly in his home province of KwaZulu-Natal.
45 dead in South Africa bus crash, 8-year-old girl only survivor
Local transportation authority says bus was carrying people to attend Easter weekend church service.
A bus carrying 46 people crashed over a bridge in South Africa, killing everyone on board except an 8-year-old girl, local officials said Thursday.
The accident happened on the Mma Matlakala Bridge between Marken and Mokopane, in the northern province of Limpopo, roughly 320 kilometres north of Johannesburg.
The Limpopo Department of Transportation and Community Safety said, in a statement posted on Facebook, the bus was believed to be carrying people who were travelling to attend an Easter weekend church service in the town of Moira.
According to the statement, it's believe the bus lost control and went over the side of the bridge and plummeted 50 metres below onto a rocky surface and caught on fire.
The child who survived the accident was transported to a nearby hospital to be treated, but details of her condition are unclear.
The bus was registered in the neighbouring country of Botswana, the department said, and officials are working to confirm the citizenship of the victims.
The statement went on to say "some bodies were burned beyond recognition," while others were either trapped in wreckage or scattered nearby.

Turkey: Polls close in Erdogan's 'last election'
Analysts say local elections this Sunday are crucial for Turkey's opposition parties, which are under threat of being utterly sidelined by an increasingly authoritarian regime.
As millions of eligible voters headed to the polls to elect mayors in 81 Turkish cities and municipalities on March 31, it is a historic local election for one person in particular: President Recep Tayyip Erdogan, who has spoken of his "last election" before handing over responsibility to the next generation.
Turkey's constitution obliges Erdogan to step down in four years due to term limits. But an Erdogan loyalist in the Turkish parliament, former Justice Minister Bekir Bozdag, has long teased a constitutional amendment that would allow the head of state to run for another term. And the president's ultranationalist ally Devlet Bahceli has publicly pleaded with Erdogan, telling him: "You cannot leave the Turkish nation alone!"
Erdogan's AKP takes on Ekrem Imamoglu
Erdogan's political career gained momentum when he was elected mayor of Istanbul in 1994. But it was there, too, that the ruling Justice and Development Party (AKP) suffered a major defeat in 2019 local elections.
This year, it hopes to erase that embarrassment. A few weeks ago, Erdogan spoke of "five wasted years." In 2019, a united opposition achieved a historic victory after 25 years and succeeded in taking back 11 cities, including Istanbul and the Turkish capital, Ankara, from the AKP.
Many factors were responsible for the defeat of the ruling party, but one man in particular stood out: Ekrem Imamoglu from the Republican People's Party (CHP), who was elected mayor of Istanbul. His reelection or defeat on March 31 could determine the future of Turkey.
If Imamoglu wins, his chances of running for president in 2028 will significantly increase, predicted Berk Esen, a political scientist at Istanbul's Sabanci University. "In my opinion, Imamoglu is the best possible opposition candidate if Erdogan's power machine is to be beaten," he said.
Esen said Imamoglu has the necessary qualities to rally a majority. "He can win the votes of very different population groups. He has the potential to reach conservative, left-wing, Kurdish and even pro-Erdogan voters," he said.
Esen also pointed out that Imamoglu was positioning himself as a direct rival to the president on the campaign trail. "Imamoglu is using these elections to attack Erdogan directly," he said.
In Istanbul, AKP may benefit from divided opposition
But it won't be easy for the anti-AKP camp this Sunday. According to a survey by the Turkish ORC research institute, there are only 1.2 percentage points between Imamoglu and AKP candidate Murat Kurum in Istanbul. The job of Istanbul mayor is of paramount importance for the country as a whole: one-fifth of the Turkish population lives in the metropolitan Istanbul region, and half of Turkey's exports as well as 56% of its imports pass through the megacity.
In the 2023 presidential election, the opposition put forward a joint candidate to face Erdogan but fell short. This time, the three biggest opposition parties — the CHP, the nationalist Good Party (IYI) and the pro-Kurdish DEM — are all presenting their own candidates.
Esen explained that the united opposition front fell apart after Erdogan's victory in the 2023 presidential election, leading to a loss of trust among voters. "In view of this fragmentation and internal struggles among the opposition parties, there is a sense of hopelessness and disenchantment with politics," he said.
When Erdogan was elected mayor of Istanbul in 1994, it was despite the fact that he had received only around 25% of the vote. His four opponents received 22, 20, 15 and 12%. Today, many fear his party's candidate for Istanbul, Kurum, could likewise benefit from such a divided opposition.
Erdogan's opponents seem unmotivated, said Ulas Tol, director of the CORE Research Institute in Istanbul. "Until 2019, Erdogan's party ruled in the big cities and the opposition's ultimate goal was simply winning elections," he said. "Now, those who don't vote for Erdogan are either emotionally politicized to the extreme or turning away from politics altogether."
Erdogan wants to 'get rid of potential 2028 rivals'
These elections will show, "which direction the authoritarian system in Turkey could develop in the coming years," said political scientist Esen.
"Erdogan wants to use these elections to weaken, or completely get rid of potential 2028 rivals," he said. "If he succeeds, the Turkish opposition will be even less able to compete than it is today. The situation is perhaps not comparable with Russia but with Venezuela: elections are held there regularly, but the opposition has no chance of winning. That's why this election is so important for the [Turkish] opposition."
