Agroforestry is the interaction of agriculture and trees, including the agricultural use of trees. This comprises trees on farms and in agricultural landscapes, farming in forests and along forest margins and tree-crop production, including cocoa, coffee, rubber and oil palm. Interactions between trees and other components of agriculture may be important at a range of scales: in fields (where trees and crops are grown together), on farms (where trees may provide fodder for livestock, fuel, food, shelter or income from products including timber) and landscapes (where agricultural and forest land uses combine in determining the provision of ecosystem services).
Agroforestry is agricultural and forestry systems that try to balance various needs:
1) to produce trees for timber and other commercial purposes;
2) to produce a diverse, adequate supply of nutritious foods both to meet global demand and to satisfy the needs of the producers themselves; and
3) to ensure the protection of the natural environment so that it continues to provide resources and environmental services to meet the needs of the present generations and those to come.

Scientists are one step closer to delaying aging By Amy Woodyatt, CNN
Updated 2305 GMT (0705 HKT) July 21, 2020
(CNN)Getting old is inevitable, but scientists at
the University of California San Diego (UCSD) may
be one step closer to being able to delay the aging
process.
[5] A team of scientists studied aging in yeast —
chosen because its cells are easily manipulated — to
try to understand if different cells age at the same rate,
and for the same reason.
What they found was intriguing. Even cells
[10] made of the same genetic materials and within the
same environment aged in "strikingly distinct ways,"
according to the scientists, who published their
findings in the journal Science.
About half of the yeast cells aged because of a
[15] gradual decline in the nucleolus, a round body located
in the nucleus of a cell, the scientists learned, by
using techniques including microfluidics and computer
modeling.
However, the other half aged because of a
[20] dysfunction of mitochondria, which produce a cell's
energy.
Scientists said that the cells go down one of two
paths — nuclear or mitochondrial — early in life, and
they continue with the aging route until they ultimately
[25] decline and die.
Researchers performed further tests to
understand how the cells behaved.
"To understand how cells make these decisions,
we identified the molecular processes underlying
[30] each aging route and the connections among them,
revealing a molecular circuit that controls cell aging,
analogous to electric circuits that control home
appliances," said Nan Hao, senior author of the study
and an associate professor in UCSD's division of
[35] biological sciences' molecular biology section.
After modeling the "aging landscape," the team
of researchers found they could manipulate — and
optimize — the process of aging, using computer
simulations to reprogram the master circuit and modify
[40] its DNA.
They were then able to create a "novel aging
route," with a dramatically extended lifespan. This,
researchers believe, could ultimately lead to the
possibility of delaying human aging.
[45] "This is an aging path that never existed, but
because we understand how it is regulated, we can
basically design or a new aging path," Hao.

World Summit on the Information Society (WSIS) Forum 2021: Information and Communication Technologies (ICTs) foster inclusive, resilient, sustainable societies and economies Acesso em: 16 jun. 2021.
The COVID-19 pandemic has illustrated two things like never before: firstly, the importance of digital technologies – where would we have been over the last year without mobile phones, radio and television broadcasting, or the Internet? – and secondly, our ever-deepening global interdependence.
Indeed, no one is safe until everyone is safe.
The pandemic has underlined the need to get everyone connected, especially in the rural and remote communities which are most underserved. Digital divides are increasingly apparent between the rich and the poor, urban and rural, and young and elderly, as well as on gender and for persons with disabilities. Investments must be encouraged, both for information and communication technology (ICT) infrastructure and to ensure affordability and digital literacy.
In the face of setbacks, efforts must be redoubled to put the sustainable development agenda back on track. Along with leveraging ICTs to drive sustainable development, governments and other partners can draw on the principles and action lines established by the World Summit on the Information Society (WSIS) back in 2003.
COVID-19 has prompted unprecedented digital infrastructure investment. Countries have expanded their fibre-optic networks, stepped up digital learning, installed free wireless access in health care facilities, and allocated free radio spectrum to help operators meet user needs.
Even so, business continuity has been hard to maintain amid recurring lockdowns. All-pervasive connectivity and new ways of interacting and doing business, including hybrid formats, need to become the norm. Technologies like AI, 5G, and the Internet of Things will be ever-more crucial to meet pressing challenges.
Based on recent experience, countries can now re-think their infrastructure and network designs to prepare for future crises. Teleworking, e-learning, and e-government capacity must be stepped up further. Digital skills gaps, evident in the pandemic, call for more investment in online education.

Agricultural economists study the effect of the ‘warm glow of giving’
More and more products carry ethical labels such as fair-trade or organic, which consumers usually view positively. Nevertheless, the sales figures of these products often remain low, even though they offer advantages for the environment or for society. A team of scientists from the University of Göttingen has investigated to what extent factors which affect consumers’ own benefit ― such as the so-called “Warm Glow of Giving” ― influence consumers’ purchasing intentions. The “warm glow” is the personal benefit that people feel when they do good. The results were published in the Journal of Cleaner Production, an international scientific publication which covers environmental and sustainable research and practice.
The researchers from the working group “Marketing for Food and Agricultural Products” at the University of Göttingen studied how two groups — one from Germany and one from the United Kingdom ― make virtual purchasing decisions. Each group consisted of around 450 consumers. Chocolate was available, which differed in terms of price, country of origin of the cocoa, and country of manufacture, as well as the ethical claims made. The claims were: organic, fair-trade and CO2 -neutral. There was also an alternative which did not make any claims. Consumers then answered questions about their purchasing intentions, values and feelings when buying.
The result: in both countries the price is the most important decision criterion, followed by the ethical claims and the country of manufacture. In addition, the “warm glow” has a comparatively large influence on the purchasing intention ― the prospect of getting a good feeling clearly attracts many consumers to buy products which make ethical claims. But the intention is often not put into practice: during the actual decision to buy, the influence of the “warm glow” is only relevant for fair-trade chocolate. The researchers assume that this is partly due to the strong association with the common good of the fair-trade label, which supports farmers in developing countries. “Other studies have shown that consumers also associate positive health aspects with organic food,” says Sarah Iweala, first author of the study and doctoral student in the “Global Food” research training group. “Of course, this dilutes the label’s association with the common good.”
In addition, the degree of recognition of the logo seems to be important. Although consumers indicated that they felt good when they reduced their CO2 footprint, this good feeling did not lead them to choose the CO2 neutral product. This can be explained by the low profile of this particular ethical logo. In both countries, less than 20 percent of the participants stated that they had already seen “carbon neutral” branding while shopping. In contrast, over 90 percent of consumers were aware of the fair-trade logo. “If consumers don’t know what a label stands for, they can’t feel good about it when they shop and so it can’t become a deciding factor in their shopping choices,” says Professor Achim Spiller, Head of the working group “Marketing for Food and Agricultural Products.”

Traditional Agricultural System in the Southern Espinhaço Range, Minas Gerais
Imagem: João Roberto Ripper
In the Espinhaço Mountain Range of in the State of Minas Gerais in Brazil, a complex agricultural system has been developed as the result of a long co-evolution between traditional communities, known as the Sempre-vivas flower gatherers, and the surrounding environment. This system is rooted in mountainous highlands whose altitude vary from 600 m to 1400 m offering a unique mosaic of landscapes and ecosystems.
The local communities have developed unique agricultural system and cultural identity based on their profound understanding of natural cycles and ecosystems, and vast knowledge regarding native flora management, achieving a great harmony with the environment and conservation of the biodiversity.
Farmers coordinate various types of agricultural activities well adapted to each differing soil, geographic and climatic characteristics to sustain their lives. They operate agroforestry gardening for their daily needs near the houses, grow a large number of species of crops in larger farmlands, collect naturally grown products, rear animals in the pastures and harvest native flowers in the high mountain areas. This GIAHS [Globally Important Agricultural Heritage Systems] runs through and composes agro-environments from the highest parts of the mountain to lower land areas.
Nowadays, the sempre-vivas flowers and the whole associated system are part of the local identity that have ensured the landscapes conservation as well as food and livelihood security of the communities.
Globally Important Agricultural Heritage Systems - GIAHS
Globally Important Agricultural Heritage Systems are outstanding landscapes of aesthetic beauty that combine agricultural biodiversity, resilient ecosystems and a valuable cultural heritage. Located in specific sites around the world, they sustainably provide multiple goods and services, food and livelihood security for millions of small-scale farmers.
Unfortunately, these agricultural systems are threatened by many factors including climate change and increased competition for natural resources. They are also dealing with migration due to low economic viability, which has resulted in traditional farming practices being abandoned and endemic species and breeds being lost.
These ancestral agricultural systems constitute the foundation for contemporary and future agricultural innovations and technologies. Their cultural, ecological and agricultural diversity is still evident in many parts of the world, maintained as unique systems of agriculture.

Black Lives Matter isn't about statues or TV shows. It's about real lives being ruined
Nosheen Iqbal
In the past six weeks, I’ve lost count of the number of times I’ve been contacted about police brutality in Britain. As a reporter, I’ve been sent photos of a black child picked up and thrown to the ground by an officer on Hampstead Heath. I’ve witnessed a dozen officers chase and aggressively pin an unarmed black 14-yearold boy on to his belly in a Tottenham park. I’ve been emailed a video of black teenagers cuffed, harassed and searched by officers while their white friend can only watch. You simply have to open your eyes and look.
These are desperate and enraging stories. Many are barely investigated and rarely reported. It’s difficult to hold the police to account on every individual case when details are lost – the officer’s badge number, or the phone number of a witness – when the victims are traumatised and worn down. Basically, when they’re real people with real lives that don’t fit the script of what makes a newsworthy victim.
It’s harder still when there is an institutional denial that something is wrong, even when the stats tells us otherwise: in London black men aged 15 to 24 were stopped and searched more than 20,000 times during lockdown, a figure that equates to 30% of young black men in the capital, although some may have been searched more than once. More than 80% of these cases led to no further action.
Every Black Lives Matter event I’ve been to in recent weeks has felt political and urgent. Black, white, brown people and more are marching for equality in jobs, housing and health. Black male graduates, for instance, are paid on average 17% less than their white counterparts; the ethnic pay gap for men and women across industries is wide and it is pronounced. This is the change people are asking for.
They want justice for black police victims, for refugees, for trans people, for Grenfell. They want protection for frontline workers dying at alarming rates from Covid-19 who, because of the way society sifts and sorts itself, disproportionately come from ethnic minorities. They are refusing to shut up and just accept small progressive gains made decade by decade. This should be inspiring for all of us; it shouldn’t be repackaged as a national threat.
If you simply want a better, more equal world, where justice is real and not simply a slogan, it’s worth attending a Black Lives Matter rally. If you can go to a protest, do. Bear witness to what is genuinely being fought for. Black Lives Matter isn’t just a viral brand. It isn’t a political party. It shouldn’t be defined by its quickest and loudest critics. As a movement, it draws in everyone, and everyone should see that they have a stake in it. Ultimately, it’s about changing all our futures for the better.
