Abstract
Drought as an eect of climate change aects the productivity and
sustainability of livestock systems. The objective of this study was to analyze
how technological land management for adaptation to climate change
adopted by livestock farmers in southern Sinaloa, Mexico, corresponds to
the typologies identied in the study area. A non-probabilistic sampling
was applied, selecting 50 production units (UP) in six municipalities of
Sinaloa, whose information was analyzed by cluster analysis and descriptive
statistics. It was identied three livestock typologies. Cluster 1 (46 %), was
dened as subsistence since its production units (PU) have few animals
and showed the smallest total surface area, the producers are the oldest and
use the shade in paddocks and the adjustment of stocking rates as drought
mitigation practices. Cluster 2 (46 %), showed the medium productive
behavior, conformed by younger producers whose PU showed a larger area
of crops and rangeland, this group adopted stocking rate adjustment, forage
conservation and species diversication as mitigation measures. Cluster 3 (8
%) showed the highest total area, livestock inventory and productivity levels;
drought mitigation decisions are focused on stocking rate adjustment and
forage conservation. The study identied mitigation practices related to land
use from the farmers’ point of view. These results can be used to conduct
studies in similar environments and to scale adaptation measures for climate
change from the local level and by type of farmer.

Introduction
Droughts are recognized as an environmental disasters and occur
in almost all climate zones, both in areas with high and low rainfall,
and are primarily related to the reduction in the amount of precipitation
received over a prolonged period, such as a season or a year. (Mishra
and Singh, 2010). Globally, the projected eects of climate change
(CC), including higher temperatures, increased concentrations of
carbon dioxide (CO₂) in the atmosphere, and changing rainfall
patterns, will aect the seasonal growth of pastures and livestock
production (Cullen et al., 2021). By 2100, CC will reduce grass
growth, which will aect annual meat and milk production, causing a
decline up to 24.9 % (Tapasco et al., 2019).
Drought has immediate eects on livestock, including depletion
of water resources, crop failure and an increase in food prices, health
eects, decreased production and death, in addition to a decrease in
prices of livestock prices (Girma and Zelalem, 2022). In Mexico,
the states with the highest general degree of vulnerability to drought
are especially those located in the northwest (Baja California, Baja
California Sur, Sonora and Sinaloa), as well as the north and some in
the south of the country (Ortega-Gaucin et al., 2018).
Livestock deaths have been observed from climate-induced
impacts such as recurrent droughts, which negatively aect the
livelihood security of farmers, pastoral and agropastoral communities
are particularly vulnerable to climate variability and changes due to
their dependence on livestock for food and sustenance (Habte et al.,
2022). In Sinaloa, livestock farming is associated with dry tropics
conditions, which reects seasonal changes in climate between the
dry and wet seasons in relation to the availability of moisture, there
may be up to eight months of drought a year in the north of the state
(Cuevas-Reyes and Rosales-Nieto, 2018).
The transition process from traditional extensive livestock farming
to sustainable livestock farming requires carrying out evaluations
related to the use of adaptation and mitigation measures specic to the
location and production system, in addition to policies that support
and facilitate their implementation (Rojas-Downing et al., 2017).
Several studies have proposed adaptation and mitigation measures
in the livestock sector (Gerber et al., 2013; FAO, 2018; Tapasco
et al., 2019). However, in Mexico, there is limited information
regarding the use of CC adaptation and mitigation technologies in
livestock farming from the producer’s perspective, and specically
to the problem of drought. The objective was to analyze how the
technological measures related to land use for adaptation to climate
change used by ranchers in southern Sinaloa, Mexico correspond to
the livestock typologies identied in the study area.
Materials and methods
Study zone
The research was carried out in 6 of the 18 Sinaloa state
municipalities (Rosario, Mazatlán, Concordia, Elota, San Ignacio and
Sinaloa de Leyva), and corresponds mainly to the central-southern
area of the state.
The study region borders the north with the municipalities of
Culiacán and Cósala, the east with Durango, the south with Nayarit,
and the west with the Pacic Ocean. 48 % of the state has a warm
subhumid climate, 40 % is a dry and semidry climate, 10 % is very
dry and is located in the northern area, the remaining 2 % is temperate
subhumid climate located in the high parts of the western Sierra
Madre (INEGI, 2023). The extreme geographical coordinates are as

the east 105°23’32”, to the west 109°26’52” west longitude (INEGI,
2021).
The type of vegetation existing in Sinaloa is known as “agostadero”
wich is a rangeland used by livestock and corresponds to the so-called
“tropical deciduous forest -BTC-” (Rzedowski, 1978), “seasonally
dry tropical forest” (Pennington et al., 2000), or also known as “Dry
Forests”. Mexico's dry forests (or BTC) represent 11.70 % of the
national territory and are distributed from the Mexican Pacic slope
to Central America (CONABIO, 2022).
Sample selection
A non-probabilistic and intentional sampling was used in order
to select the sample, (Quinn, 2002; Hernández, 2021). In the six
municipalities there are 7,533 production units with cattle that
correspond to 36.8 % of total state, thus the sample (n=50) reached
0.66 % of the total productive units in the study area (INEGI, 2022).
This type of sampling was used due to the high costs of carrying out
probabilistic sampling, in addition to avoiding or reducing the risk
of crime problems when applying the questionnaire. The criteria for
selecting the producers were the following: 1) they must be dual-
purpose livestock producers (representative system of Sinaloa), 2)
they agreed to answer the survey, 3) they have participated in state
government rural extension programs. After applying the criteria, 50
producers were interviewed.
Information collection techniques
A questionnaire was developed and applied to obtain information
related to the social characteristics of the producer, as well as aspects
related to the characterization of the production unit (PU): agricultural
resources for the production of forage (total area, sown, area of
rangeland), livestock inventory, milking days (refers to the number of
days that producers milk), productive aspects of livestock activity and
number of months that the PUs have a shortage of forage. To carry
out the Cluster analisys, 14 quantitative variables related to the social
aspects of the producer, agricultural resources, livestock inventory,
and production were selected (table 1). These variables, according to
the literature, inuence the use and adoption of technology (Feder et
al., 1985; McNamara et al., 1991).

In addition, we asked which technological practices were used for
adaptation to drought conditions as a result of CC (we asked whether
they used: paddock shading, stocking rate adjustment, species
diversication, forage conservation and silvopastoral systems). Thus,
the indicators of the technology use for climate change adaptation
(drought) correspond to the percentages of PU where these practices
were performed. The eldwork was carried out during the rst quarter
of 2022.
Data analysis
The clustering criterion was Ward’s linkage method and the
measure of association was the squared Euclidean distance. In
Ward’s method, the distance between two clusters is calculated as the
sum of squares between groups, and seeks to minimize intragroup
variance and maximize homogeneity within groups (Vilà-Baños et
al., 2014). The standardization of the variables was performed using
the Z score in SPSS. When variables are recorded in dierent units,
a Z-score transformation will put the variables on a common scale to
compare sets of variables taken with dierent measurement systems
(Pérez, 2008). Subsequently, the dendrogram was elaborated and the
typologies were characterized. The description of the groups was
carried out using descriptive statistics. The analysis of the drought
adaptation technologies indicators was carried out by frequency
analysis. The analyses were performed with SPSS 27.0 Windows
software (IBM, 2022).
Results and discussion
Typology of Production Units
The cluster analysis allowed classifying the livestock production
units into three dierentiated groups: Cluster 1 (C1, n=23) comprises
46 % of PU, Cluster 2 (C2, n=23) represents 46 %, while Cluster 3
(C3, n=4) represents only 8 % of total analyzed sample (gure 1).
Figure 1. Dendrogram of livestock production unit typologies.
Social characteristics
The producer's age and the number of children in their families
were quite similar for the three clusters: farmers were under 60 years
old and had between two and three children. C1 producers were the
oldest on average, while C2 and C3 producers were the youngest,
with an averaging 54 years. The producers interviewed are relatively
young and may be more receptive to the use of new technologies.
Regarding the distance from the production unit to the municipality,
Cluster 1 is 12.5 km away, Cluster 2 is 23.6 km away and Cluster 3 is
30 km away (table 2).

In this sense, a study on CC adaptation practices indicates that
young producers with more education and economic resources are
more likely to use CC adaptation practices (Ali and Erenstein, 2017).
Land use and forage shortage
C1 has a smaller total area (36.8 ha average), less sown area and
less grazing land than the other clusters. C2 has an average total area
of 53.5 ha for forage production, while C2 has 17.4 ha and 30.8 ha of
average sown and rangeland, respectively. In contrast, C3 shows an
average of 52 ha of total agricultural area, 52.5 ha for sowing and 90.2
ha of rangeland (table 3).

The planted area uses mainly dual-purpose (grain and forage)
sorghum Gavatero-203 and corn (Zea mays) to a lesser extent. The
sorghum variety (Sorghum bicolor L. Moench) Gavatero-203 has an
average yield of 2,849 kg.ha
-1
of grain and 35,367 kg.ha
-1
of green
forage (Hernández et al., 2010). The herbaceous stratum plays an
important role in livestock feeding during the rainy season, with
species of the Acanthaceae family, commonly known as bull grass
because of its forage importance, and species like Carlowrightia
arizonica and Dicliptera resupinata, among others standing out in the
rangelands (Guízar et al., 1994).
This land utilization does not produce enough forage, so there
is a pasture shortage of 3.3 (C1), 3.9 (C2) and 3.7 (C3) months per
year, so producers are forced to buy forage in the dry season. Rojas-
Downing et al. (2017), point out that, the lack of forage produced
by environmental stress caused by events such as droughts, directly
aects pasture productivity as well as the physiological well-being of
animals and their reproductive health.
Total cattle in the production units
On average, C1 has 46.1 heads of total cattle (herd), C2 has 60,
and C3 has 165 heads of total cattle. Of all livestock heads, C1 and
C2 each have 18.8 and 20 adult cows on average, while C3 has 59
adult cows. The number of sires is relatively similar for C1 and C2,
while C3 has 3 on average (table 4). These values coincide with those
reported by Bautista-Martínez et al. (2021) who found three strata
and one of the main dierentiating characteristics was herd size and
structure. However, in our study, it has been found that in Cluster
3, the total number of sires can negatively inuence reproductive
parameters due to an inadequate sire-cow ratio.

Livestock productivity
Livestock productivity by groups is presented in table 5, it
is observed that C1 shows a daily milk production of 10.3 L, C2
produces 76.7 L and C3 has a production of 232.5 L.day
-1
; with this
information and the average number of milking cows, it is obtain a
daily average production per cow of 4.6 for C1, 6.0 for C2 and 7.0 for
C3. In Clusters C2 and C3, cows are milked for more than 9 months
a year (270 days a year), while in C1 only about one month a year is
milked (table 5).

The number of calves produced ranged from 8.9 for C1 to 22.7
for C3. Milk production per cow (4 to 7 L.day
-1
) agrees with Juarez-
Barrientos et al. (2015) in a study conducted in dual-purpose systems
in Veracruz, Mexico.
Milking days are carried out during a certain time of the year (one
to ve months), however, the PUs that have fewer cows (such as C1),
leave the calf to consume the milk in order to sell it in a shorter time
(six months), with an average weight of 220 kg.
Livestock drought adaptation technologies
Adaptation of extensive livestock farming refers to the set of
measures and adjustments needed in production practices to reduce the
negative eects of climate change (CC) (Villavicencio et al., 2023).
Five drought adaptation measures or technologies used by the cattle
ranching groups in the study region are analyzed in table 6: paddock
shading (PS), stocking rate adjustment (SRA), species diversication
(SD), forage conservation (FC) and silvopastoral systems (SPS).

Pasture shade
The benet of having trees dispersed in the paddocks is reected
in obtaining various products such as wood, food, shade and fruit
for livestock (Esquivel-Mimenza et al., 2011). The use of SP was
reported by 34.8 % of the production units in C1 and C2; however,
producers of C3 do not use this practice. This measure uses the
resources available in the pasture in the state of Sinaloa, for cattle

feeding during the rainy season; the shrub layer and low trees,
smaller than ve meters (Guízar et al., 1994), which are found in
the BTC rangeland. According to Esqueda et al. (2011), the most
representative trees of the BTC in Mexico are copales (Bursera spp.),
pochotes (Ceiba spp.) and tepeguaje (Lysiloma sp.), as well as several
columnar cacti.
Adjustment of stocking rate
In Mexico, the number of cattle in at least 24 states is estimated to
be higher than the carrying capacity, depending on forage production
(Enríquez et al., 2021). The SRA is carried out to a greater extent
(75 %) by producers in C3 (this cluster shows the largest herd size),
followed by C2 (47.8 %) and nally 39.1 % in C1 production units. It
is important to mention that this activity is not carried out to seek less
overexploitation of forage resources, but as a subsistence strategy,
since the producers sell part of their herd (young animals or adult
cows) in order to purchase fodder for the dry season (Cuevas-Reyes
and Rosales-Nieto, 2018).
Species diversication
Biodiversity is essential for the functioning of ecosystems and
human well-being through the provision of environmental services
(Pimm et al., 2014). 43.5 % of C2 producers indicated having
conducted SD, followed by C3 producers with 25 % and in last place
with 21.7 %, were C1 producers. In the study area, local research
centers have focused on the diversication of forage species adaptable
to drought, such as pearl millet (Pennisetum americanum L. Leeke),
which has a higher eciency in the use of rainwater compared to
traditional crops such as corn or sorghum (Reyes et al., 2022). In
addition, several varieties of sorghum and grasses such as Pretoria
(Dichanthium annulatum (Forssk.) Stapf), Callie (Cynodon dactylon
(L.) Pers.), llanero grass (Andropogon gayanus Kunth) and buel
grass (Cenchrus ciliaris L.) are used (Loaiza, 2011).
Forage conservation
The practice of FC is performed by the three types of producers
(in C1 it is performed by 26.1 %; 47.8 % in C2 and 75 % in C3),
this activity requires having agricultural implements such as tractors,
trailers and silos to store forage. It is an activity that allows having
good quality forage for the dry season, however, it is mainly carried
out by producers owning the largest agricultural area (Cuevas-Reyes,
2019).
Silvopastoral systems
The establishment of SPS contributes to sustainable livestock
production because it reduces the impact on natural resources and
increases the eciency and protability of an area; in addition,
sanitary and phytosanitary measures improve food safety and animal
welfare (Chará et al., 2019). In 34.8 % of the production units of
C2 there are SPS, 25 % in C3 and 21.7 % in C1, as mentioned by
producers who implemented this technology. Generally speaking, it
was identied that two of the ve practices used (load adjustment and
species diversity) coincide with studies carried out in other research
projects. Abazinab et al. (2022) found that reduction of the population
size of livestock and diversication of the species for cattle are
measures of adaptation to CC applied by the ranchers.
Conclusions
Three typologies of livestock production units were identied.
Cluster one (C1) could be dened as subsistence, since its productive
results are very low, it was observed very few animals and the smallest
available total area (both sowing and rangeland); these producers are
the oldest of the three groups and use paddock shading and stocking
rate adjustment as drought mitigation practices.
Cluster two (C2), performed the medium behavior, it is formed
by youngest producers, whose cows showed an adequate length of
milking period and productive results (per milking cow) in the tipical
range reported for these production systems. This Cluster showed
a larger total area, with more planting and pasture available area;
it stands out due to adopting the most eective drought mitigation
practices: stocking rate adjustment, forage conservation and species
diversication.
Group three (C3) comprises the youngest producers, who have the
largest average livestock area and inventory. These are economically
active production units given their levels of productivity characteristic
of dual-purpose grazing systems of the Latin American tropics. The
drought mitigation decisions of these producers are focused on
stocking rate adjustment and forage conservation.
The study made it possible to identify, in the selected sample,
drought mitigation practices related to land use from the producers’
point of view. These results can serve as a reference to carry out studies
in similar environments to improve the use of technologies and scale
adaptation measures from the local level and by type of producer to
mitigate drought problems in pastoral livestock in tropical areas that
use tropical deciduous forest vegetation.
It is recommended that a probabilistic sampling and longitudinal
approach be used for future work to validate the results of this study
in relation to the use of adaptation measures throughout a production
cycle.
