Illegal cattle farming in the Brazilian Amazon

Illegal cattle farming has been a significant issue in the Brazilian Amazon for many years. The expansion of cattle ranching has been a leading cause of deforestation and environmental degradation

Land Grabbing: Illegal land grabbing is a common practice associated with cattle farming in the Amazon. People encroach upon protected areas, indigenous lands, or public lands, illegally claiming ownership and converting them into cattle ranches. This further exacerbates deforestation and undermines the rights of indigenous communities.

Violation of Environmental Laws: Illegal cattle ranching often involves the violation of environmental laws and regulations. These include implemented. Additionally, consumer awareness and pressure have led some companies to commit to sourcing only deforestationfree beef.

However, tackling illegal cattle farming requires a comprehensive approach that includes stricter enforcement of environmental regulations, land tenure regularization, support for sustainable land use alternatives, and addressing the underlying socio-economic factors driving deforestation.

Action urgently needed

Glaring World Cost Anomalies

Positive:

Glasgow COP 26

$12 billion donor support pledged to halt and reverse forest loss and protect land rights.

A new public finance pledge from 12 countries to support ambitious forest-related climate action in developing countries.

Negative:

During a recent visit by President of Brazil, Luiz Inácio Lula da Silva, President Biden pledged 1 Billion pounds towards Rainforest conservation.

Da Silva went on to China but it is reported President Xi Jinping was unwilling to pledge any amount in the region. While not all cattle farming in the Amazon is illegal, there are illegal practices associated with the industry that contribute to deforestation and other environmental problems. clearing forests without proper permits, operating in protected areas, and using illegal means to obtain land titles.

Here are some key points about illegal cattle farming in the Brazilian Amazon: Deforestation: The expansion of cattle ranching has been a major driver of deforestation in the Amazon. Forests are often cleared illegally to make way for pastureland for cattle. This not only leads to the loss of valuable ecosystems but also contributes to climate change by releasing large amounts of carbon dioxide into the atmosphere.

Supply Chain Issues: The beef produced through illegal cattle farming can enter the formal supply chain, making it difficult to trace the origin of the meat. This creates challenges for companies and consumers who seek to avoid supporting deforestation and human rights abuses associated with illegal practices.

The Brazilian government has made efforts to address illegal cattle farming and reduce deforestation rates. Initiatives such as increased law enforcement, satellite monitoring, and the expansion of protected areas have been

The global warming crisis is increasing at an alarming rate. Rising temperatures are fuelling environmental degradation, natural disasters, weather extremes, food and water insecurity, economic disruption, conflict, and terrorism. Sea levels are rising, the Arctic and Antarctica are melting, coral reefs are dying, oceans are acidifying, and forests are burning.

Create a World Fighting force

Now is the time for the United Nations to make a radical decision. Create a fighting force that has to be adopted by Brazil, The Congo Basin countries and others to step up policing and putting an end to illegal logging, illegal cattle farming etc or face the dire consequences of intense global warming.

• Consider the cost of a nuclear submarine $3.45 billion

• The war in Afghanistan is estimated to have cost upwards of 2.2 trillion dollars.

• The HS2 UK rail extension is likely to cost upwards of 100 billion pounds.

• The 2023 US defence budget is Circa $770 billion.

• The 2023 Chinese defence budget is $224 billion dollars.

• That’s around 1 Trillion dollars from 2 countries in 2023!

How much is needed to save the Amazon and The Congo basin et al?

Hardly anything in comparison.

Continued from Page 15 important in both structures and finishes. The Japanese are big fans of light Finnish wood raw material, and JAS ensures that other visual quality requirements are also met,” says Virmiala.

Piece by piece

Quality control is an important part of retaining certification. In addition to annual inspections by an external auditor, the company must commit to internal quality control. Besides regularly inspecting the planing mill’s measurement equipment and preparing protocol on the inspection, the finished products are randomly inspected every 20 days. One or two batches may be inspected per day, and it takes roughly two hours to inspect one product.

“We take 200 pieces of wood out of the packages, go through them piece by piece to see if the quality measures up to the requirements in the manual,” explains Kylökäs.

A total of six products fall within the scope of certification, and each one undergoes an inspection. Currently two employees are responsible for internal quality control, in addition to which a third person takes part in the inspections for learning purposes. ensures a machine with great stability, excellent manoeuvrability, and low ground pressure. The Komatsu 951XC is also optimised for use with the Komatsu C164 – a harvester head specially designed for logging large trees – although naturally it works just as well with a range of other heads.

“Hardly any other product is inspected so thoroughly. My eye is now already trained to notice planing deviations and whether the settings need adjusting,” says Kylökäs.

From a production perspective, quality control related to certification is quite laborious, but Virmiala nevertheless believes that JAS will boost Koskisen’s sales opportunities in Japan.

“Previously, we mainly imported Genban products and certain planed products, but now we can import products that we wouldn’t have been able to sell without JAS,” Virmiala concludes.

Launching Komatsu 951XC

For demanding conditions

The Komatsu 951XC is part of Komatsu Forest’s product series of machines specially designed for challenging conditions.

“Now we have a complete range of eight-wheeled machines, specially designed for demanding conditions,” Joakim Johansson, Product Manager Harvesters at Komatsu Forest says.

Compact yet strong

The machine design is much like that of the Komatsu 951, although there are some differences. The Komatsu 951XC has the same wheel size as the 931XC, lending the machine a more compact design and giving the 951XC a total machine length that is shorter than that of the Komatsu 951.

The Komatsu 951XC has 242 kN of underlying tractive force and unique interaction between engine, control system and power transmission. The hydrostatic transmission enables engine power to be fully utilised, providing considerable advantages in difficult terrain as well as excellent climbing ability. This is much due to the machine’s large hydrostatic pump, which can maintain higher speeds at high tractive forces.

“What is special about the 951XC is that it combines the strength of a 951 with an extremely compact design. Since it has about the same dimensions as the 931XC it can be used in denser stands,” Joakim explains.

951XC is also equipped with hub reductions. They provide an advantage when working in challenging conditions, such as steep, snowy, or wet terrain, as they increase the life of the bogie and thereby machine reliability.

The Komatsu 951XC has new working hydraulics to better utilise the diesel engine. The new hydraulics also provide faster feeding from start to maximum speed and allow the saw motor to work even more efficiently.

“The new working hydraulics contribute to a feeling of an even stronger engine according to the test operators that have been working with 951XC,” Joakim states.

Although the working hydraulics are new, in all other respects the Komatsu 951XC shares the same proven design as other Komatsu harvesters, meaning 3PS.

“This enables several crane and head functions to be used simultaneously with retained maximum hydraulic power, all thanks to the machine’s hydraulic power coordination,” Joakim continues.

Powerful crane

All Komatsu harvesters are equipped with parallel cranes, this has been the case since 1999. With the Komatsu Forest design concept, the lifting booms and outer booms are linked, thereby eliminating an entire aspect of crane control. This concept simplifies crane operation by ensuring that the head is always in level regardless of crane cycle stage. The parallel crane is also cleverly designed to be fast in its outward movements, when the head is unloaded, and powerful in its return movements, when the head is heavily loaded.

Compared to the 951, the Komatsu 951XC has a significantly shorter distance from the centre of the crane to the front wheels. This creates a larger working area in front of the machine, that enables the operator to work at shorter reaches.

“The new larger working area in front of the machine means more powerful crane movements. And for those who equipes their machines with Smart Crane they get an even more easily manoeuvred crane with excellent precision,” Joakim explains.

Operator environment

The Komatsu 951XC, just like all other Komatsu harvesters, features a high-performance operator environment. Examples of the many advantages include the spacious cab, good visibility and comfortable cab climate.

Thanks to the machine’s stability and levelling cab, the operator is always seated level without the need to stretch and strain to maintain a good seating position. The 951XC is, as all Komatsu harvesters, based on the tried-and-tested Komatsu concept that offers favourable weight distribution and has a low centre of gravity. In addition, the eight-wheeled XC series harvesters have a double oscillating bogie on the rear frame giving the machines completely unique handling characteristics.

“Our double oscillating bogie on the rear frame is an innovation of which we’re very proud. As well as increasing stability by lowering the machine’s centre of gravity, the machine follows irregularities in the terrain in a forgiving manner while delivering excellent manoeuvrability in challenging terrain conditions,” Joakim ends.

The work to develop a new machine is a massive team effort. Before a new machine model is launched prototypes are thoroughly tested first with Komatsu’s own test operators and then by contractors working in environments suitable for the specific machine model. One of the contractors, Henrik Lysebäck at Lysebäcks Skogsentreprenad, tested a prototype of the 951XC in the fall of 2022 and concludes the test like this;

“The 951XC is a good machine, stable and comfortable to operate. It is a machine you can trust, and you feel secure working at a long reach. This is definitely a machine I would like to continue to work with.
