“…Precipitation and winds on the insect population influence population dynamics, reproduction and survival rate, the plants suffer mechanical damage to their organs making them susceptible to damage by pathogens and pests, weeds, weeds and spontaneous plants, within the cultivated, redistribution in their hosts and migrate towards cutivated plants; originating redistribution of payments with wind and water (Crispin, et al [9]). Drought and high temperatures affect the oviposition or food of insects, generating selection of the insect population on crops (invasive pests); such as the heminoptera and thysanoptera genus because the rise in temperature favors the reproduction of these insects, by favoring the dispersion of exotic insects and pests that alter the population of beneficial insects (Hamada,et al [9,10]) [11][12][13].…”

Climate change is the result of energy demand and atmospheric emissions derived from fuel combustion, forest burning, greenhouse gases, among other anthropogenic causes. In Mexico, more than 90% of the energy generated is from polluting sources. The great challenge for universities is to train students in a multidisciplinary way to integrate knowledge and technology to be benign to climate change. This change is produced by humans, and it is they who can generate solutions and correct it.

“…These global changes have had a noticeable impact on various regions, including the Mediterranean, where frequent occurrences of higher temperatures, erratic precipitation patterns, and extreme winter and summer droughts have been observed [5,6]. These events have raised concerns about the ability of traditional crops, particularly the olive tree (Olea europaea L.), which thrives in both hot and dry summers and moderately cold and wet winters, to cope with the adverse effects of climate change [7][8][9][10][11].…”

In recent years, occurrences of heat waves and drought have become increasingly frequent, highlighting the undeniable impact of climate change. The rise in temperatures and decline in rainfall have had severe repercussions on olive trees’ behavior and olive oil production. This study aims to evaluate the effects of two-year climate variations on olive oils from centenarian olive trees situated in the Côa Valley region of Northern Portugal. A selection of 25 centenarian plants was made, and the climate influence on fatty acid content, tocopherols, individual phenols, oxidative stability, and antioxidant activity was assessed over two consecutive years. During the second year of the study, a significant variation (p-value < 0.05) in the proportion of palmitic acid was observed, which increased from 12.9% to 13.6%. Conversely, stearic and arachidic acids exhibited a decrease from 2.7% to 2.3% and from 0.37% to 0.35%, respectively. Analysis of the oils revealed a noteworthy difference (p-value < 0.05) in the concentration of β-tocopherol. The concentration of oils derived from hydroxytyrosol and tyrosol significantly decreases (p-value < 0.005) during the second year. Additionally, significant differences (p-value < 0.005) were observed in the total phenol content and the percentage of ABTS inhibition, both of which decreased in the second year. These findings reinforce the notion that climatic conditions play a key role in shaping the composition of olive oils.

“…Such areas represent the recharge and flow regulation zones that are crucial for national water supply [10,11]. The expansion of conventional agriculture in the region has been driven by an economic need, thereby increasing crop productivity, primarily with the use of agrochemicals [12][13][14][15]. As such, conventional agricultural production represents one of the main means of income for socioeconomically vulnerable communities in the region.…”

Conventional agricultural practices, such as the use of agrochemicals, implementation of monocultures, and the expansion of crops in strategic ecosystems, have significant impacts in Andean basins, directly increasing nutrient inputs to waterways, and contributing to ecological fragility and socioeconomic vulnerability. This complex dynamic is related to land-use change and production activities that affect the provision of hydrological ecosystem services. This study presents an integrated analysis of socioecological interactions related to water quality in the Las Piedras River basin (LPRB), a water supply basin located in the Andean region of southwestern Colombia. The analysis was conducted over a five-year monitoring period to assess the spatiotemporal variation and correlation of water quality between streams and agricultural runoff water within the LPRB. Furthermore, water quality indices were calculated based on physicochemical and biological parameters to evaluate the impact of land-use/land-cover changes and agricultural activities within the basin. Results demonstrate that different types of actors, productive logics, mechanisms of use, and access to water within the basin affect water quality and uncertainty for water management, while facing socioecological conflicts between actors.
