Crop wild relatives - looking at trends in genetic diversity to inform conser...Bioversity International
Presentation given by Elena Fiorino, Imke Thormann and Ehsan Dullo from Bioversity International on the closing day of the International Horticultural Congress 2014.
In their presentation they tackle questions such as 'Why is in situ conservation of crop wild relatives important?' and 'How can we develop in situ conservation strategies?'

Conservation Priorities for Tree Crop Wild Relatives in the United StatesCWRofUS
Presentation on conservation priorities of tree crop wild relatives of the U.S., given at the Gene Conservation of Tree Species – Banking on the Future Conference, 16-19 May 2016 in Chicago, USA
Partnering on CWR research at three scales: commonalities for successCWR Project
The potential for crop wild relatives (CWR) to contribute to crop improvement is growing due to improvements in information on species and their diversity, advancements in breeding tools, and the growing need for exotic genetic diversity to address compounding agronomic challenges. As wild plants, CWR are subject to a myriad of human caused threats to natural ecosystems, and their representation ex situ is often far from comprehensive. Ex situ conservation of many of these wild plants is also technically challenging, particularly in an environment of insufficient resources. Enhancing conservation, availability, and access to CWR requires a spectrum of action spanning basic and applied research on wild species to inform on-the-ground collecting, ex situ maintenance, and germplasm utilization. The development of effective information channels and productive partnerships between diverse organizations are essential to the success of these actions. Here we report on a spectrum of CWR activities involving broad partnerships, at three levels: a) the collaborative compilation and distribution on over 5 million occurrence data records on the CWR of major food crops, b) the analysis of conservation concerns and genetic resources potential of the CWR of potato, sweetpotato, and pigeonpea, and c) ongoing efforts to map the diversity and conservation concerns for CWR in the USA. Although differing in scales and depth of collaborations, the success of these initiatives are largely due to commonalities in research orientation, e.g., inclusiveness, offering clear incentives for involvement, and service providing to the crop science community.

Carbon in dryland soils. Multiple essential functionscsfd
Bernoux M. & Chevallier T., 2014. Carbon in dryland soils. Multiple essential functions. Les dossiers thématiques du CSFD. N°10. June 2014. CSFD/Agropolis International, Montpellier, France. 40 pp.
Soil organic carbon (SOC) has a key role in the overall behaviour of soils and agroecosystems. Increasing its content enhances soil quality and fertility, thus improving agricultural resilience and sustainability and, in turn, food security of societies. Soils also contain the largest pool of carbon interacting with the atmosphere. Agricultural and forestry systems that reduce atmospheric carbon concentrations by sequestering this carbon in biomass and in soil organic matter are carbon sinks. Combating desertification contributes to soil carbon sequestration, thus mitigating global warming, while contributing to sustainable agricultural management.
Soils have only recently become a global environmental issue, especially in the framework of three international environmental conventions. These conventions have interrelated issues, especially with respect to dryland regions—desertification, climate change and biodiversity loss. Few tangible policies have, however, been drawn up concerning carbon in dryland regions. The impact of agricultural, pastoral and forestry activities on the carbon cycle need especially to be taken into greater account.
In the current carbon market system, carbon volumes of agricultural and forestry sectors are low as compared to those of other sectors (industry, etc.). Moreover, these markets do not fully recognize all activities that are conducive to carbon sequestration in agricultural soils, particularly in drylands. Carbon markets have so far been focused on checking amounts of carbon sequestered, whereas it would be much easier, and verifiable, to directly promote recognized ‘carbon sequestering’ practices. Such a market could provide much more efficient operational leverage for modifying agricultural practices and setting up systems to protect soils in dryland regions.
The overall objective of this initiative is to provide documented knowledge and evidence on the diverse pathways of sustainable intensification of African agriculture and its value chains. It will cover agriculture and ecological sciences, as well as economic, social and policy sciences and will promote transdisciplinary approaches. This initiative will undertake collaborative, world-leading research with a wide range of stakeholders in Africa and Europe on the sustainable intensification of agriculture to meet major societal challenges.
The environment has been erroneously perceived as a god’s-given resource to be explored and exploited for production of goods and services necessary for the satisfaction of human needs and comfort. This perception inspired man to engage in breath-taking explorations into the huge vaults of the heavens with ozone layer depletion, green house effect as consequences resulting to global warming, climate change, loss of biodiversity on one hand and pollution, deforestation, flooding, draught, famine, flood, extreme weather events on the other hand, as global catastrophic threats to human kind. These problems have become a major concern of the international community who has called for a new type of education for a better understanding of the complexity of the problems of the environment as well as for effective management of environmental resources. This type of education is referred to as environmental education. This paper explored the library as a medium for the dissemination of knowledge of the environment and its problems. It explored various ways through which knowledge of environmental problems and their prevention is promoted through the instrumentality of the library. It concludes that library as a reservoir of knowledge should be equipped with materials containing information on environmental problems and as well as be made accessible to all humans in every part of the globe.| Publisher: International Journal of Research and Innovation in Social Science (IJRISS)

Identification and marketing of Marantaceae in the Ndjolé area, in central Ga...Innspub Net
The forests of the Congo Basin cover an area of 200 million hectares, of which just over 10% is in Gabon. In this country, crop products and non-timber forest products (NTFPs) are abundant because of its favourable climate. There is significant biodiversity and great potential for non-timber forest products. This study is interested in the identification and the supply chain of the Marantaceae, one of these NTFPs of plant origin in central Gabon, whose exploitation is national. Through a survey of the main actors in the sector and field visits in the locality of Bifoun, it emerges the existence of three large groups of exploited marantaceae, whose harvest and transport are mainly done by women, in various containers. The storage of this NTFPs does not exceed four days, with the risk of losing its commercial value due to drying out. The uses of this resource are multiple: processing cassava, cooking food, making handicrafts, etc. The income it provides to producers is mainly use towards small family expenses but helps to monetize the rural world. The difficulties inherent in the distance from harvesting points, the low price of the product and the impossibility of long-term storage of the marantaceae leaves constitute a brake on the development of this activity. It would therefore be wise to envisage the domestication of the species listed for a sustainable use of this plant genetic resource.

We analyzed the abundance and diversity of soil macrofauna and measured the physical properties of soil in order to study the influence of the inclusion of legumes in Silvopastoral systems. In addition, the soil sampling was performed aiming to evaluate the soil heterogeneity caused by the grazing preference when legume-tree are included.
La Acción de Mitigación Nacionalmente Apropiada (NAMA) de la Ganadería Bovina –la “NAMA bovina”– es una política pública cuyo propósito es orientar la transformación del sector hacia prácticas bajas en carbono, dentro de un contexto integrado de sostenibilidad ambiental, social y económica. La NAMA bovina propone un conjunto de acciones voluntarias, denominadas medidas de mitigación del cambio climático, orientadas a reducir las emisiones
de gases efecto invernadero (GEI), provenientes de la producción ganadera en los predios, a niveles inferiores a los que se tendrían bajo un desarrollo sectorial, sin la introducción de estas medidas. Entre estas acciones, está configurar sistemas productivos ganaderos ricos en vegetación, con la capacidad de absorber y retener carbono y de proveer alimento con un alto contenido de nutrientes.
Con respecto a la financiación e implementación de las medidas de mitigación propuestas, estas se materializarán con la estrecha coordinación de esfuerzos públicos y privados a través de proyectos, políticas y programas del sector bovino que incorporen, en sus objetivos, la mitigación del cambio climático.

Russian anarchist and anti-war movement in the third year of full-scale warAntti Rautiainen
Anarchist group ANA Regensburg hosted my online-presentation on 16th of May 2024, in which I discussed tactics of anti-war activism in Russia, and reasons why the anti-war movement has not been able to make an impact to change the course of events yet. Cases of anarchists repressed for anti-war activities are presented, as well as strategies of support for political prisoners, and modest successes in supporting their struggles.

1. GLOBAL STRATEGY FOR CONSERVATION & UTILISATION
OF TROPICAL AND SUBTROPICAL FORAGES Issue 9 – August 2019
The International Grassland Congress (IGC)
was scheduled for southern France, when
one of us (BLM) was about to finalize her
PhD thesis in Germany. It could be expected
that the global state of the art in forage and
grassland sciences was to be presented in
that quadrennial event, and networking was
of highest priority for most participants. Alas,
Nice was still far from Germany in 1989 and,
when the submission deadline passed, I was
disappointed to have missed this opportunity
to meet with former mentors, colleagues,
friends from CIAT-Colombia. As things even-
tuated, I had commenced a postdoctoral
position in the Amazon lowlands of Peru,
when the congress actually took place.
Not participating certainly impeded first
face-to-face meetings with Australian re-
searchers who had kicked off the R&D work
on Stylosanthes—my thesis was on S. scabra,
an important tropical legume that nobody
cared for in Germany in that time, though.
Our view is that strong collaboration and
international interaction was often initiated
through events such as the IGC and done
much better than today, despite the absence
of today’s communication tools. No internet
existed, no skype, no emails, and no cell
phones. Working in Pucallpa/Peru, as I was in
1989, was like being ‘behind the mountains’—
fully out of reach, but somehow still linked to
what was happening elsewhere in the world
through CIAT’s institutional connections.
Today, such placement should be much
easier with cheaper and shorter flights, and
diverse communication tools! Yet despite the
many benefits that could flow from close
collaboration via easier communication, few
key genebank personnel and/or forage
researchers have ever met each other, let
alone collaborated in any way.
When revising the content of our first 8
newsletters, we found that we have been
able to get stories that highlight certain
species (30%) as a resource as well as on
success stories and impact generated from
forage utilization (40%). However, we have
almost nothing on the transition from the
genetic resource to impact—the agronomy
work and on fitting forages to farming
systems and into particular socio-ecological
niches. This is critical work that is being done
but, it seems, seldom told. So, how many
untold stories remain? It has been increa-
singly more difficult to encourage people to
contribute their story and, perhaps, it’s time
to conclude this newsletter. In our view, there
probably is no substitute for face-to-face
meetings and discussions and networking.
The next IGC is scheduled for October 2020.
Attending that meeting should, in our view,
be a priority for the up-and-coming forage
researchers of the world, who will carry the
torch into the future. Please note that the
submission deadline is coming up very
quickly, and that we both hope to meet you
at the joint International Grassland &
Rangeland Congress in Nairobi, Kenya 2020
to build the networks and tell those untold
stories.

Newsletter vs. Blog
“A newsletter is a printed report containing news (infor-
mation) of the activities of […] an organization that is
sent by mail regularly to all its members, […] or people,
who are interested in. Newsletters generally contain one
main topic of interest to its recipients. A newsletter may
be considered grey literature.” (Wikipedia)
“A blog is a type of website where the content is pre-
sented in reverse chronological order (newer content
appear first). Blog content is often referred to as entries
or ‘blog posts’. | Blogs are typically run by an individual
or a small group of people to present information in a
conversational style. However, now there are tons of
corporate blogs that produce a lot of informational and
thought-leadership style content.” (Wordpress)
In summary, a blog could be defined as an instrument to
meet new people, whereas a newsletter is used to make
a deeper connection with people already known.

The 24th International Grassland Congress
(IGC) will take place in Africa for the first
time. This conference will celebrate its
centenary soon, as the first congress was
held in 1927 (Humphreys 2005). In 2020, it
will take place in conjunction with the
11th International Rangeland Congress (IRC)
in Nairobi, Kenya. The IRC has only been
established in the late 1970s in response to
the view that “rangeland scientists became
dissatisfied and frustrated with the … pro-
grammes of the International Grassland
Congresses [which] had very little rangeland
content and were largely irrelevant” for them
(Perry & Le Houerou 1991). 2020 is only the
second time that these two major congresses
will be held together after China in 2008.
Hosting the first-ever joint IGC/IRC in Africa
is significant for Kenya, as East Africa offers
diverse and unique tropical savannah eco-
systems and is home to some of the most
economically important grasses of the
tropics and subtropics. While this first ever
African happening is a landmark in the
history of the IGC, it is not so for the IRC,
which has been less Eurocentric than the IGC,
in part perhaps, because of the distribution
of the major rangelands of the world (see
figure on IRC venue regions).

Evolution of the IGC
During its long history, the IGC has evolved
from a congress largely dominated by wes-
tern European participants (see figure) to
one, whose perspectives have become more
global. However, the majority of countries
hosting IGCs are still biased towards those of
western Europe (see World in Numbers, p. 6).
The conference has changed slightly in
thematic areas covered and in the weight of
each of them. In his analysis of 19 IGCs (1927-
2001), Humphreys (2005) found that the
number of contributions in some domains
showed a downward trend, while others had
increased. Interestingly, the ‘Plant genetic
base’ theme, including forage genetic
resources and plant breeding, remained fairly
stable at ~21% of all contributions over the
same period. Yet, the analysis does not cover
the split between contributions on grazing
vs. cut-and-carry systems or, in fact, the
balance between temperate and tropical
systems, but this would certainly be telling.
The 2020 Congress aims to promote the
interchange of scientific and technical
information on all aspects of grasslands &
rangelands, including a diverse range of
research and development areas (see p. 8).

Genetic resources
Buffelgrass (Cenchrus ciliaris L.) is an impor-
tant forage grass particularly in the semi-arid
areas of the subtropics and tropics. Origina-
ting in Africa, Arabia, the Middle-East and
India, it is also widely cultivated in Australia,
and the Americas. The International Live-
stock Research institute (ILRI) maintains over
200 accessions, collected from 19 African
countries, in its forage genebank. The
collection offers a valuable resource for the
selection and development of new varieties
and, with this in mind, ILRI and the Instituto
Nacional de Investigaciones Forestales,
Agrícolas y Pecuarias (INIFAP) in Mexico
have been working together to evaluate the
performance of these materials. This project
‘Conservation, Characterization and use of
forage genetic resources for priority grazing
land ecosystems of Mexico’ (2013-2016) was
also about capacity building.
Characterization in Ethiopia
The first study was carried out at ILRI’s
experimental station in Bishoftu, Ethiopia on
a vertisol soil, at 1850 metres above sea level
(asl.), with average annual maximum and
minimum temperatures (Tmax/Tmin) of
25 and 11°C, respectively, and an average
annual rainfall of 850 mm. Significant diversi-
ty in agronomic, morphological and nutri-
tional characteristics was identified in the
collection with one group consisting of eight
accessions being more productive than all
others. This group included 11 commercial
cultivars, with which they were compared.
In a second study performed at ILRI’s Zwai
Experimental Station (loamy sand at 1,640 m
asl., Tmax/Tmin 26/20°C, and with 600 mm
annual rainfall), which included 10 commer-
cial cultivars, four clusters of accessions were
identified with one group, consisting of six
accessions, having exceptional character-
istics in both forage and seed production.

Genotyping
More recently, ILRI has started a genotyping-
by-sequencing initiative on its collection to
complement the agro-morphological data
and investigate the possibility of initiating
marker assisted selection in this species. So
far, we have genotyped 185 accessions
collected from across the origin countries
and identified over 200,000 molecular
markers, which were mapped to the genome
of Foxtail millet (Setaria italica), a closely
related species. Using a subset of 1,000 of
these markers distributed across the S. italica
genome, we have sorted the accessions into
two main groups with up to 8 sub-groups in
the collection at ILRI, none of which align
with the geographic origin or cluster based
on agronomic traits so far.

4. FORAGES FOR THE FUTURE | Issue 9 4
Shortage of feed in terms of quantity and
quality, particularly during the dry season, is
a major constraint to livestock production in
the tropics, and this will likely be exacerbated
by climate change. Crude protein (CP) and
energy are the main limiting nutrients during
the dry season in grazed rangelands. Sub-
Saharan Africa is endowed with a variety of
native forage legume species, which are well
adapted to harsh conditions, but their poten-
tial as feed has not been exploited. In 2012,
the University of Namibia (UNAM) obtained
a research grant from the Regional University
Forum for Capacity Building (RUFORUM) to
characterize indigenous legumes in Nami-
bia’s rangelands with a potential to enhance
livestock productivity. 14 native species were
collected from the wild and identified, four of
which (Vigna lobatifolia, Otoptera burchellii,
Crotalaria argyraea and Lablab purpureus
subsp. uncinatus—wild lablab) were further
investigated for palatability and intake.
These forage legumes are widely distributed
in central Namibia, where average annual
rainfall ranges 135-350 mm; and they have
been observed to be consumed by goats.
Nutritional composition and
palatability
Forage legume samples were randomly
collected from the wild across different
seasons and locations. Leaves and young
branches were harvested at different growth
stages. The table shows least squares means
of the chemical composition. CP content
ranged 18-22 %, well above the minimum
threshold of 7% required to support rumen
microbial function; NDF was 36-56%, being
below the 55-60% range that would limit
intake. A palatability trial conducted in
October 2014, using the cafeteria method,
showed that Boer goats readily ate all the
forages offered, but C. argyraea was less
preferred, possibly, because of undesirable
chemical constituents such as pyrrolizidine
alkaloids or flavonoids (Lucena et al. 2010).
Description
Vigna lobatifolia Baker is a perennial
herbaceous, trailing and tuberous legume with
trifoliate leaves. It flowers shortly after the
end of the cold season (September to April),
maybe an adaptive feature to produce seed
early in the summer season for dispersal.
Otoptera burchellii DC. is a perennial
herb, often trailing or climbing, with hairy
stems up to 2 m long. Its leaves are trifoliate
with leaflets lanceolate to ovate and up to 10
× 3.5 cm in size, blue-green, pointed at the
apex with a long, mucronate tip. Flowers are
purple. Pods are up to 12 × 0.8 cm in size.
No germplasm collection exists as yet. Most
research was performed through two MSc-
theses (Kaholongo 2016 & Thamina 2018).

explosive dehiscence.
Lablab purpureus subsp. uncinatus
Verdc. (wild Lablab) is a perennial twining
herb with comparatively small fruits, ca. 4 cm
x 1.5 cm. It is probably a progenitor of the
commercially used lablab.

Conclusion
Besides the studied legumes being naturally
well adapted to harsh environmental
conditions and their ability to fix nitrogen,
the selected native species showed their
potential as fodder and protein source for
ruminants to enhance livestock productivity.
Further research, however, is needed to
effectively deploy native forage legumes.

Stylosanthes pellets: a healthy and sustainable animal feed
Recently, Fudesemillas has developed methodology to produce animal feed using leaf meal produced
from the tropical legume Stylosanthes, combined with other locally produced ingredients. Fudesemillas
is a non-profit organization located in southern Costa Rica, dedicated to developing and implementing
innovative agricultural technologies for adding value to rural products since 1990. The technology is based on growing, sun-drying, grinding and
making feed pellets from a Stylosanthes guianensis cultivar that contains 5 anthracnose-resistant lines. Stylosanthes is a perennial crop, which
yields three or four times more protein/ha/year than soybeans. A quite recent paper in Outlook on Agriculture provides all the details.

5. FORAGES FOR THE FUTURE | Issue 9 5
The dairy sector in Tanzania has continued to
suffer because of low productivity despite
increasing numbers of improved animals and
availability of large land tracts for grazing.
Climate change, coupled with more frequent
and prolonged drought, has only made the
problem more severe. However, the develop-
ment of new forage varieties has brought
hope to increase productivity of the sector.
Climate-smart dairy systems
The International Center for Tropical Agricul-
ture (CIAT) is leading a research for develop-
ment project on ‘climate-smart dairy
systems’. The project is funded by The Inter-
national Fund for Agricultural Development
(IFAD) and implemented through national
partnerships with the Tanzania Livestock
Research Institute (TALIRI) in Tanzania and
Rwanda Agriculture Board (RAB) in Rwanda.
It aims to help farmers to increase their
production, storage and (year-round) avail-
ability of high quality feeds. This will in turn
enable farmers become reliable suppliers of
milk and engage in commercialization.
Climate-smart forage options (grasses,
legumes) integrated into mixed production
systems are also among the most relevant
options to increase resilience and reduce the
ecological ‘hoofprint’ or greenhouse gas
emissions of dairy production. Particular
attention has been given to climate-robust
options increasing productivity while, at the
same time, enhancing environmental bene-
fits (soil fertility, greenhouse gas mitigation).
In 3 districts of the southern highlands of
Tanzania (Njombe, Mufindi-Iringa, and
Rungwe-Mbeya), improved forages grasses
and legumes have been tested in demo plots:
Urochloa (syn. Brachiaria) hybrids cvs.
Cayman and Cobra, Cenchrus purpureus (syn.
Pennisetum purpureum, Napier grass) Ouma,
Napier ILRI 16835, Chloris gayana (Rhodes
grass), Tripsacum andersonii (Guatemala
grass), Lablab purpureus, Stylosanthes
guianensis and Desmodium intortum (Green-
leaf). In addition, training, seeds and cuttings
are provided to farmers so that they can
plant the forages in their own farms.
Farmers have already reported benefits from
feeding these forages to their animals. High
biomass yield, persistence in dry seasons,
and significant increase in milk yield are the
main observed positive impacts.

with ready hay.
A farmer’s experience
David Mshindo, a farmer from Njombe, is
one of the beneficiaries. Not only has he
established an additional Brachiaria field, but
he has also discovered that using a motor-
ized tea pruner works efficiently in cutting
the grass, allowing it to dry in the field for
hay. This has boosted his cows’ milk
production, especially in the dry season, and
is benefiting his family. His son, a university
graduate, has also ventured into yoghurt
production at home, packing and distributing
to his customers on his motorbike, and
thereby contributing to his income.
While depending on rain only to grow these
forages, farmers can harvest the Napier and
Guatemala grasses more than 6 times a year
and the legumes and Brachiaria and Rhodes
grass up to 4 times.
Brachiaria grasses had the highest impact on
milk yield with an average increase of 1.5-2
liters per milking time and when fed with
either of the legumes the yield increased to
2-2.5 liters per milking time. Farmers also
noted a reduction in the time it took to
search for natural forage, of which 90%
become unavailable during the dry period.
From Rhodes to Brachiaria
Interestingly, these improved forages have
also become a direct source of income. In the
past, it was common for farmers in the
southern highlands and elsewhere in the
country to make hay from Rhodes grass. But
now they have switched to Brachiaria.

Lameck Mshindo, David’s son, is measuring milk
in readiness for yoghurt processing.
Farmers are selling a bale of Rhodes grass
hay (12-15 kg) at USD 1.4, and a bale of
Brachiaria hay (20 kg) at USD 6.9 (May 2019).
The introduction of these forages in the
southern highlands of Tanzania has
motivated more farmers to keep improved
breeds of cows with the aim of increasing
milk yield. Unlike in other highly populated
areas such as Lushoto district in Tanga
region, farmers in the southern highlands are
growing the forages in plots and not in
contours as barriers for controlling erosion
but as their core source of animal feed. This
is attributed to the fact that farmers still have
enough land for growing both forages and
food/cash crops. Farmers in Bukoba, Mwanza
and Tanga are now motivated to start
growing Brachiaria.

6. FORAGES FOR THE FUTURE | Issue 9 6
The Urochloa breeding program was initiated
in 1988 at the Centro Internacional de
Agricultura Tropical (CIAT), in Cali, Colombia,
led by John W. Miles. Urochloa (syn.
Brachiaria) is a large but poorly delimited
genus comprising more than 100 species.
The three economically important species
(U. decumbens, U. brizantha, U. humidicola)
belong to two of nine identified taxonomic
groups. The first comprehensive germplasm
collecting mission for this genus was carried
out in the mid-1980s in eastern Africa, where
approx. 800 accessions were collected.
Today, this collection is mostly maintained as
a field collection both at the International
Livestock Research Institute (ILRI) in Ethiopia
and CIAT in Colombia; and also largely dupli-
cated with Embrapa institutes in Brazil.
The collection provides a solid base for the
development of new Urochloa cultivars, like
Mulato II, Cayman, Cobra and Camello.
Mulato II is a vigorous grass with deep and
branched roots; Cayman has been released
due to its strong waterlogging tolerance;
Cobra is used in cut-and-carry feeding sys-
tems; and Camello is outstanding for
drought resistance (see characteristics table).

Under very intensive grazing every 2 weeks
in South Florida during 2010-2012, Urochloa
hybrids, cvs. Mulato II and Cayman, had
significantly higher percentages of leaf
(70−80%), crude protein (19−21% in leaves,
10−12% in stems) and in vitro organic matter
digestibility (IVOMD, 73−75% in leaf, 59−61%
in stem) than other lines tested. These key
values of forage quality are similar to those
usually reported for temperate grasses.
Hybrids of Urochloa obtained previously from
CIAT were interspecific and had low and in-
consistent seed production ranging 0-1 t ha-1.

7. FORAGES FOR THE FUTURE | Issue 9 7
Background
The species Andropogon gayanus Kunth is a
tropical forage grass original from sub-
Saharan Africa and of recognized agronomic
value for its adaptation to acidic and low-
fertility soils. It is characterized by growing
and thriving very well in dry tropical areas,
including well-drained savannas. In Mexico,
the species was introduced through CIAT’s
Tropical Pastures Program in 1982.
300,000
Currently in Mexico, the grass covers approx.
300,000 hectares, predominantly located in
areas that are considered marginal due to
drought, limiting the production of agricultu-
ral crops. In 1986, INIFAP (Instituto Nacional
de Investigaciones Forestales, Agrícolas y
Pecuarias) released Andropogon gayanus
cv. Llanero in Mexico. Farmers have identi-
fied this cultivar because of the low cost of
the seed and its attributes of high forage pro-
duction, resistance to drought, resistance to
pests and diseases, vigor of regrowth at the
beginning of the rainy season, and for its
good capacity for natural repopulation by
seed. Yet, it’s great height of up to 4 m, also
resulting in low leaf:stem ratio, triggered the
selection of a lower (up to 2 m), much leafier
type that is now being commercialized.
The most important areas of A. gayanus are
marginal lands mainly located along the Pa-
cific slope in the states of Guerrero, México,
Michoacán, Jalisco and Sinaloa. Various go-
vernmental supports have been decisive for
the rapid adoption of this important grass.
Dry season feed
The main impact of this grass in the semi-
arid zones of tropical Mexico is because it has
arrived to solve problems of forage scarcity
in the dry season, since it offers high biomass
production during the rainy season. The use
and management of the plant is mainly
under grazing conditions. However, as the
dry season progresses the plant becomes
lignified and, thereby, restricted to make
best use of the forage on foot. Simultaneous-
ly, and as plant maturity advances, the nutri-
tive value decreases, especially in terms of
crude protein content and total digestibility.

Grass seed production
National grass seed production has also
played an important role in the rapid growth
of existing surfaces. The production and
harvest of seed is carried out by small
livestock producers in paddocks established
with pastures. They use hired laborers who
cut the mature inflorescences and put them
to sweat, shake them when dry and, finally,
pack them for sale. In the last years of the
20th century, several state agricultural devel-
opment agencies provided training services
to producers for the production, manage-
ment and benefit of ‘llanero grass’ seed. Even
so, the main objective of sowing the grass
has never been seed production; it is a
welcome by-product of small-scale livestock
activity in Mexico.

Invasive plant, major weed?
Andropogon gayanus has been introduced for
pasture improvement worldwide. In some
regions, especially in Australia, the grass is
considered a major invasive that strongly
contributes to hotter bushfires than from
natural grasslands (e.g. Rossiter-Rachor et al.
2009; Setterfield et al. 2010; Neale 2019).
In contrast, it appears to be an appreciated
grass, well adapted to several rather
marginal semi-arid areas of tropical America.
