Morning frosts have hit Serbian fruit production hard, mainly affecting early stone fruit varieties.

In the Čačak region, experts from the Institute of Fruit Growing report that 95% of apricot crops have been destroyed.

The damage varies by location, with Vojvodina experiencing more than 90% loss in lowland areas, while areas near Belgrade show 40-50% damage.

Cherries and pears have also suffered, with a complete damage assessment expected by the end of April.

Fruit trees provide many ecological benefits – they are trees, after all! A properly-stewarded fruit forest can provide many of the benefits of a native forest while also providing an abundance of wholesome and delicious food! No tilling the soil, no killing the plants at harvest time, and no wasted vertical space. Fruit trees are also the gift that keeps on giving, producing food for decades and producing seeds and other propagation materials in order to spread the abundance, no profit incentive needed! Share with your friends, share with your neighbours, share with the birds – you'll have so much food, you'll be giving it away! Shifting to a tree-based agriculture would also free up a huge amount of land, allowing native forests to regrow, which would have an enormous benefit for the climate. Fruit trees are the ultimate win-win situation!

While agrivoltaics in vineyards isn't novel, the extent to which SolarWine leverages the panel's capabilities to adapt to the weather is unique.

SolarWine uses machine learning to guide the folding panels on when to provide needed shade for the grapes or take in excess energy. The panels can also be used as protection against heavy rainfall and wind. It all amounts to a win for farmers, who can control the weather and generate passive income as they do it.

Significance

The productivity of staple crops is a key factor shaping the affordability of food and the amount of land and other resources used in agriculture. We synthesize evidence on how the weather faced by these crops has changed and how these changes have affected productivity. Most cropping regions have experienced both rapid warming and atmospheric drying, with significant negative global yield impacts for three of the five crops. Models can largely reproduce these changes and impacts with two important exceptions—they overstate warming and drying in North America and understate drying in most other temperate regions. These insights can help to guide adaptation efforts and model improvements.

Abstract

Efforts to anticipate and adapt to future climate can benefit from historical experiences. We examine agroclimatic conditions over the past 50 y for five major crops around the world. Most regions experienced rapid warming relative to interannual variability, with 45% of summer and 32% of winter crop area warming by more than two SD (σ). Vapor pressure deficit (VPD), a key driver of plant water stress, also increased in most temperate regions but not in the tropics. Precipitation trends, while important in some locations, were generally below 1σ. Historical climate model simulations show that observed changes in crops’ climate would have been well predicted by models run with historical forcings, with two main surprises: i) models substantially overestimate the amount of warming and drying experienced by summer crops in North America, and ii) models underestimate the increase in VPD in most temperate cropping regions. Linking agroclimatic data to crop productivity, we estimate that climate trends have caused current global yields of wheat, maize, and barley to be 10, 4, and 13% lower than they would have otherwise been. These losses likely exceeded the benefits of CO2 increases over the same period, whereas CO2 benefits likely exceeded climate-related losses for soybean and rice. Aggregate global yield losses are very similar to what models would have predicted, with the two biases above largely offsetting each other. Climate model biases in reproducing VPD trends may partially explain the ineffectiveness of some adaptations predicted by modeling studies, such as farmer shifts to longer maturing varieties.

Have you ever had an especially rewarding, adventurous, dangerous, or really stupid experience of harvesting/foraging fruit?

I tend to live a sheltered life, so I don't have anything too exciting to share. I've harvested bananas with a hornets' nest on the underside of a leaf multiple times, but nothing unusual ever happened. I've gone wading through the swamp looking for aguaje, but the anacondas had already been hunted to extinction in that area. I've stood under a fruiting durian tree without a helmet, but it seems that durians don't just fall from the sky when I'm hungry.

Does anyone have an exciting or uplifting story to share?

WASHINGTON COURT HOUSE, Ohio (AP) — Stubborn drought in Ohio and the shifting weather patterns influenced by climate change appear to be affecting North America’s largest native fruit: the pawpaw.

Avocado-sized with a taste sometimes described as a cross between a mango and banana, the pawpaw is beloved by many but rarely seen in grocery stores in the U.S. due to its short shelf life. The fruit grows in various places in the eastern half of North America, from Ontario to Florida. But in parts of Ohio, which hosts an annual festival dedicated to the fruit, and Kentucky, some growers this year are reporting earlier-than-normal harvests and bitter-tasting fruit, a possible effect of the extreme weather from the spring freezes to drought that has hit the region.

Take Valerie Libbey’s orchard in Washington Court House, about an hour’s drive from Columbus. Libbey grows 100 pawpaw trees and said she was surprised to see the fruit dropping from trees in the first week of August instead of mid-September.

“I had walked into the orchard to do my regular irrigation and the smell of the fruit just hit me,” said Libbey, who added that this year’s harvest period was much shorter than in previous years and the fruits themselves were smaller and more bitter.

Invidious

• Monoculture palm oil production has come at the cost of rainforest habitat, particularly in Malaysia and Indonesia.
• Researchers are conducting experimental trials in Malaysian Borneo to see if native trees can be planted in oil palm plantations without significantly reducing palm oil yields.
• While still in the initial stages, the experiment is so far showing there are no detrimental effects to oil palm growth.
• In fact, interplanting with native forest trees may benefit oil palm, with the researchers finding oil palm trees had more leaf growth in agroforestry plots than in monoculture ones.

Well... it's a start.

Just a few years ago, the Sahel region at the northern edge of Senegal was a "barren wasteland" where nothing had grown for 40 years. But the United Nations World Food Programme (WFP) and local villagers teamed up to regreen the area, bringing back agriculture, improving the economy of the people who live there, and preventing the climate migration that desertification ultimately leads to.

In a recently published study, researchers offer a new tool to compare how different crops affect the environment in different regions.

Named PLANTdex, the tool assesses the environmental impact of a crop by considering five key indicators — greenhouse gas emissions, freshwater biodiversity loss, marine biodiversity loss, land biodiversity loss, and water resource depletion — study co-author Mark Jwaideh, nature data and risk analytics lead at the University of Oxford, told Mongabay by email.

For each crop, PLANTdex combines these five indicators into one score at a high resolution of 9 by 9 kilometers (5.6 by 5.6 miles).

“This granularity enables the identification of specific regions where crop production is more or less environmentally impactful, facilitating targeted interventions and policy decisions,” Jwaideh said. “This approach enables stakeholders to pinpoint environmental hotspots to make informed decisions on crop commodity sourcing or where better management is required.”

Hey kids, I had an idea again. So I performed this highly scientific study.

Introduction

U know wound adhesive spray? It's basically super glue you spray on wounds to close them and prevent germs and dirt from entering.

Theory

If we share 50% of our DNA with bananas, then I have a 50/50 chance that it can also work on plants.

To verify this highly scientific theory, I made a small experiment.

Steps to reproduce

Step 1: Choose a victim.

I chose this poor motherfucker.

Step 2: Surgery

Grab the most disgusting and dullest knife you can find, and cut a dent in it.

Step 3: Spray adhesive on the cut

(I accidentally made a carnivorous plant? Cool!)

Step 4: Wait a day

If we just would have left it as it, it would be absolutely dead by now in the summers heat.
But it isn't, surprise!

Learning

That stuff closes wounds on plants very good. I see no necrosis, despite probably hitting the vegetable artery. It's like nothing ever happened.

As a professional idiot I approve that method and will from now on use it when I'm accidentally beheading one of my beloved greens again.

Thanks for listening to my TED talk, see ya at my nobel prize award

Abstract

Climate change is an emerging threat to global food and nutritional security. The tropical fruits such as mango, bananas, passionfruit, custard apples, and papaya are highly sensitive to weather changes especially; changes of monsoon onset and elevated temperature are influencing crop growth and production. There is a need for more specific studies concerning individual crops and regional variations. Long-term effects and interactions of weather parameters and increased concentration of greenhouse gases, especially carbon dioxide, with phenological stages of the plant, pests, and diseases remain understudied, while adaptation strategies require further exploration for comprehensive understanding and effective mitigation. Few researchers have addressed the issues on the effect of climate change on tropical fruits. This paper focuses on the impact of abiotic (temperature, rainfall, humidity, wind speed, evaporation, carbon dioxide concentration) and biotic (pest and pathogens dynamics) factors affecting the fruit crop ecosystem. These factors influence flowering, pollination, fruit set, fruit yield and quality. This review paper will help develop adaptive strategies, policy interventions and technological innovations aimed at mitigating the adverse effects of climate change on tropical fruit production and safeguarding global food and nutritional security.

• Climate change is colliding with land use practices, deforestation and biodiversity loss to drive a rapidly growing threat of crop pests.
• Future warming of 2° Celsius (3.6° Fahrenheit) above preindustrial levels (likely by the 2040s or 2050s, according to current projections) could see substantial losses of staple crop yields for wheat (an estimated 46% loss), rice (19%) and maize (31%) due to pest infestations, according to a recent paper.
• Temperate regions are likely to see the greatest increases in crop pests as warming creates conditions for migrating subtropical species to establish themselves in previously unhabitable areas.
• The authors underline the need for more pest monitoring, diversification of farmland crops and biotechnological solutions to meet this growing threat.

Note that future warming is likely to be up to 50% greater than stated in this article.
