This paper discusses the global transition to sustainable and wildlife-friendly farming systems that protect ecosystem services while also providing economic equity in Java, Indonesia. Java is home to 60% of Indonesia’s population as well as many endemic species, and therefore the management of agriculture alongside human well-being and biodiversity is vital. The authors look at a community of 400 coffee farmers in West Java to assess the steps needed to develop a community-wide, wildlife-friendly program. An adaptive management approach through consultations and co-learning with stakeholder, researchers, and policy makers, was used to create a framework with common objectives. The expectations of the program were to see an increase in income and an increase in coffee quality, but that there would also be implementation challenges. The quality of the coffee plantations were assessed before and after the implementation of program, finding that coffee quality was significantly improved through efforts that converted farms to organic. The benefit of this method is that wildlife-friendly farming areas contain much higher biodiversity than intensive farming areas. However, not as biodiverse as natural ecosystems. Further success will depend on farmers keeping constant involvement in their understanding of long-term sustainability or at least until farmer are able to receive a premium price for their coffee.

Lerner, et. al
This paper addresses the issue of unfair trade practices, investigating the drivers of the differences between farm-gate and free-on-board (FOB) prices in the most important Arabica coffee producing countries worldwide: Brazil, Guatemala, Colombia, Honduras, Peru, and Ethiopia. Our study looks at those differences taking into account the literature on governance in agri-food chains, with a focus on each country’s domestic market. We performed panel-corrected standard error (PCSE) estimates in ICO and World Bank data, covering the period from 2007 to 2016. In the paper we analyze (i) property rights as a proxy of transaction costs, once it brings more transparency and support to negotiations; (ii) access to electricity as a proxy of supporting infrastructure in communication and information activities, and (iii) quality of roads and quality of ports as proxies of transportation infrastructure. Our results show that heterogeneity in institutions and infrastructure are key in explaining the differences between farm-gate and FOB prices. The transaction costs derived from institutional failures and infrastructure gaps, lead to the use of intermediaries in the coffee supply chain, and this reduces the margin for coffee farmers. Actions that aim to reduce these inefficiencies bring more transparency and lower transaction costs, thereby directly contributing to the United Nations (UN) Sustainable Development Goals (SDGs).

Djufry, F. & Wulandar, S.
Coffee crops are susceptible to climate change. Coffee agribusiness is demanded to respond to the
increasing need for Climate-Smart Agriculture (CSA). As a CSA model, coffee cattle integration offers
farmers risk management strategies and options to adapt to climate change. Issues about GAP, soil
management, water management, and ecological objectives can be addressed well in Integrated Crop
Livestock Systems. Constraints in adopting coffee cattle integration as CSA practices are related to
production input, labor, knowledge, technology, capital, and farmer institution. Strategies for
implementing coffee cattle integration as a CSA practice is carried out in a hierarchical stage. It starts
with developing a support system to improve agricultural support policies, promote public-private
partnerships, and support community assistance and facilitation center, followed by the increasing
availability of capital through credit farm.

Carbon neutral labeling of food products is a market-based approach to reduce carbon footprints in the agri-food sector. To better understand consumers’ preferences and attitudes towards a carbon neutral label on globally traded agri-food products, the willingness to pay (WTP) of German consumers for a carbon neutral label on specialty coffee was examined. A discrete choice experiment was conducted in Germany, where coffee is often sold with multiple labels or claims, in order to examine the WTP for alternative combinations of a carbon neutral label with either a Fair Trade label or a claim of direct trade coffee sourcing. Choice data were analyzed using random parameter logit models which determined a positive WTP for the carbon neutral label. This estimate exceeds the corresponding marginal costs of certification and the marginal social cost of carbon, yet it is relatively lower than the estimated WTP for the Fair Trade label and the direct trade claim. A positive synergy effect on utility was also determined for the combination of a carbon neutral label and a direct trade claim. If no additional information was provided, consumers often perceived coffee as a “natural product” that does not generate any greenhouse gas emissions. Thus, awareness-building policies are needed to make carbon neutral labels an effective market-based tool to reduce greenhouse gas emissions in the agri-food sector.
A christmas coffee story

Legends and myth. Apocrypha and simple fictions. It’s that time of year. Coffee has at least one oft-told holiday story and it, too, is a combination of fact and fabrication, or things we just don’t know to be true.
If you want to take the long way around, and we do, our story begins but does not end with John Arbuckle, a man who it seems to me would be happy enough if remembered as a coffee roaster and not much more. But he was much more. He was a philanthropist, innovative entrepreneur, “trust buster,” and inventor. He held several patents on coffee roasters and improvements to the coffee roasting process. He held a patent, appropriately, on a method for fireproofing buildings. He also, it is worth mentioning, invented mittens that included a tube so you could blow warm air from your mouth directly onto your fingers. The last patent he applied for was a method for raising sunken ships, a method so significant in its design that even 60 years later subsequent patent applicants for similar procedures were obliged to cite Arbuckle’s work. That ship lifting patent was approved, but not until after his death in 1912. But we’re getting ahead of ourselves. We’ve killed him already and he hasn’t even been born yet.

Mwesigye, F., Nguyen, H.
Uganda, like other sub-Saharan African countries, continues to experience increasing levels
of youth unemployment in view of its rapid population growth in recent decades. Such a
trend exerts mounting pressures on the overall capacity of the national economy to generate
adequate numbers of decent jobs to absorb the working age population.
The country depends on agriculture as a source of livelihood and foreign exchange earnings.
The country’s 2015/16–2019/20 Agriculture Sector Strategic Plan identified coffee as one
of the 15 priority commodities that the Government of Uganda is focusing on to promote
growth, development and employment creation.
In its effort to support the Government to enhance youth employment in agriculture, in
2018 FAO launched a selection process to identify the value chain with the greatest potential
to boost youth employment. Based on considerations of economic and socio-political
feasibility, as well as overall sustainability considerations, national youth and agriculture
stakeholders have decided on pursuing actions in the coffee value chain.
This study was therefore commissioned to analyse the coffee value chain and identify
constraints and opportunities for youth employment. It also aimed at suggesting upgrading
options and policy actions that could realize the potential for creating and enhancing youth
employment in the coffee sub-sector.

Coffea arabica (Arabica) and Coffea canephora (Robusta) are the two primary cultivated species of Coffee. However, there are many other Coffea species that have not yet been evaluated that can offer traits useful for future breeding programs to ensure sustainability of the crop.
Wild coffee species have desirable traits that could be incorporated into Arabica and Robusta coffee cultivars. Genebanks provide access to both cultivars and wild species for breeding programs and to determine preferred cultivars for diverse growing conditions

Popular with consumers around the world and supporting numerous developing nations as one of their key commodities, the coffee industry is both valuable and – up to the beginning of 2020 – expanding.
However with Covid-19 slowing both production and demand, and disrupting the global supply chain, the global coffee industry has stalled in recent months – and seen new trends take hold.
Here’s our summary of the key factors set to affect the coffee industry in 2021 and beyond.
Coffee buying and sustainability in cafés in helsinki
Café, Coffee Buying, Coffee, Sustainability, Corporate Sustainability
Oct 09, 2020
There are not many things done repeatedly day after day, but drinking coffee is one of
them. Coffee is one of the most popular beverages in the world and essential part of daily
life to many. Cafés are visited for different reasons, whether to work or socialise, but often
a cup of coffee is enjoyed on side. Cafés aim to ensure good coffee for their customers.
Though, farming that brewed cup of coffee requires a significant amount of resources.
Environmental sustainability is perhaps one of the most pressing issues in the modern
world. Increase in environmental efforts on the commercial stage leads people to expect
cafés too to take sustainability seriously.
This thesis focuses on the final phase of the value chain of coffee, consumption, with a
focus on the coffee buying process of cafés. The purpose of this thesis is to find out what
factors have an effect on the decisions cafés in Helsinki make about the coffee they buy. In
this thesis, coffee buying is viewed as the action of cafés buying coffee from a roastery.
The thesis examines the decisions made by the person in charge of buying coffee in a café
and is limited to cafés located in the capital city of Finland. The objective is to determine
the main factors that influence the buying of coffee in cafés located in Helsinki, and the
research question and investigative questions are created based on this objective. The
investigative questions aim to find out the criteria set for the bought coffee, the thoughts on
the future of coffee and the sustainable operations in and outside of coffee buying in the
Two major topics, coffee and sustainability, are addressed in the literature review. The
theory helps to describe the key concerns related to the cultivation and purchase of coffee.
This thesis uses the qualitative approach of data collection, in the form of semi-structured
interviews. In total of five interviews were conducted during April 2020. Together with
literature review, the interviews with the selected cafés prove that coffee buying should be
done with sustainability in mind.
The interview findings show that importance of good coffee and sustainable actions as part
of business are evident. The views on sustainability and actions taken differ between
cafés. The cafés all find it important to buy coffee that tastes good and is of good quality.
The findings reveal that all cafés buy their coffee from a roastery and trust the roastery to
offer them best possible coffee. Though, the research showed that the taste is not the only
important thing to keep in mind. Availability of coffee at the time the coffee is bought is also
considered important. Also, for every coffee purchase the cafés make, they cast a vote for
environmental sustainability, for labour conditions and global justice. The research made it
relatively clear that the majority of Finnish consumers are not too interested in the quality,
taste, origin or sustainability of coffee. These four factors mentioned, however, greatly
influence the decisions related to coffee buying in cafés

The objective of this study was to evaluate the volatile composition and the sensory effect of the presence of Quaker beans in natural specialty coffee beverage and, consequently, to confront the requirement of the Specialty Coffee Association regarding the total absence of Quaker beans in a natural specialty coffee batch. Sensory analysis and volatile composition were performed for three different colorations of Quaker beans, added separately to natural specialty coffee samples at seven different concentrations. Beans with color equal to or above Agtron 82.8 negatively affected the sensory characteristics of natural specialty coffee only from the presence of 7 Quaker beans in one cup (65 beans). Through the analysis of volatile composition, volatile compounds formed during roasting were identified in Quaker beans from precursors present in raw immature beans. Therefore, the color and sensory characteristics of Quaker are a consequence of the chemical composition of an immature bean.

The brew temperature is widely considered a key parameter affecting the final quality of coffee, with a temperature near 93 °C often described as optimal. In particular, drip brewers that do not achieve a minimum brew temperature of 92 °C within a prescribed time period fail their certification. There is little empirical evidence in terms of rigorous sensory descriptive analysis or consumer preference testing, however, to support any particular range of brew temperatures. In this study, we drip-brewed coffee to specific brew strengths, as measured by total dissolved solids (TDS), and extraction yields, as measured by percent extraction (PE), spanning the range of the classic Coffee Brewing Control Chart. Three separate brew temperatures of 87 °C, 90 °C, or 93 °C were tested, adjusting the grind size and overall brew time as necessary to achieve the target TDS and PE. Although the TDS and PE both significantly affected the sensory profile of the coffee, surprisingly the brew temperature had no appreciable impact. We conclude that brew temperature should be considered as only one of several parameters that affect the extraction dynamics, and that ultimately the sensory profile is governed by differences in TDS and PE rather than the brew temperature, at least over the range of temperatures tested.

How does your favorite Barista create your Cafee Latte or your Flat White? Yes, it's a known fact that drinking black is a much healthier option but sometimes drinking coffee with milk just tastes awesome. Whichever way we like it, adding milk in our coffee does give texture and softens the bitterness in coffee.
Properly steamed microfoam brings out the natural sweetness that milk offers into your cup of coffee.
Let's read what's the impact of milk in our coffee - the good and the bad.
Climate risks to Brazilian coffee production

koh, et. al
Brazil is the world's leading coffee exporter, contributing billions of dollars to the global food economy. Yet, a majority of Brazilian coffee farms are operated by 'smallholders', producers with relatively small properties and primarily reliant on family labor. While previous work indicates that climate change will decrease the area suitable for coffee production in Brazil, no study has assessed the impacts of climate change on coffee yields or the relative exposure and vulnerability of coffee producing regions to changes in climate hazards (climate-associated losses in yield). To address these knowledge gaps, we assess the sensitivity of coffee yields to temperature and precipitation variation from 1974 to 2017 to map coffee climate hazards. Next, we identify which coffee producing regions in Brazil have the highest exposure to climate hazards due to high dependence of coffee production as a proportion of agricultural area. Finally, we generate a Vulnerability Index to identify which regions are theoretically least able to adapt to climate hazards. Our study finds that since 1974, temperatures in Brazilian coffee growing municipalities have been increasing by ~0.25 °C per decade and annual precipitation has been decreasing during the blooming and ripening periods. This historical climate change has already resulted in reductions in coffee yield by more than 20% in the Southeast of Brazil. Minas Gerais, the largest coffee producing state in Brazil, has among the highest climate hazard and overall climate risk, exacerbated by ongoing coffee expansion. Additionally, many municipalities with the lowest adaptive capacity, including the country's mountainous regions, also have high climate exposure and hazards. Negative climate hazard and exposure impacts for coffee producing regions could be potentially offset by targeting climate adaptation support to these high-risk regions, including research, extension, and credit subsidies for improved coffee varieties, irrigation, and agroforestry and diversifying agricultural production.
