Confronting Climate Change: Challenges and Opportunities for Peru’s Ecosystems
Peru’s stunning landscapes invite you to explore its breathtaking hiking and trekking routes, showcasing the country’s majestic mountains, snow-capped peaks, terraced hills, and sacred valleys.
This region, a cradle of ancient civilization, reflects a rich legacy of harmonious coexistence with the remarkable Andean geological formations, all while achieving impressive levels of development.
However, climate change poses significant challenges.
The impacts are especially harsh in the Andean mountains, threatening the glaciers that supply vital water resources.
These changes lead to droughts and landslides, jeopardizing both the diverse biological ecosystems and human livelihoods throughout the region, including Cusco.
Peru is also recognized for its remarkable genetic diversity, ranking among the top eight global centers for agricultural and livestock diversity, as well as plant and animal genetic resources.
By harnessing this knowledge, we can work towards sustainable progress that protects our delicate ecosystems.
Water in the Andes is far more than a “vital resource”; it is crucial for consumption, agriculture, and energy generation, underpinning ecosystem integrity and Andean culture.
Glacial and rainwater feed streams that serve as the primary water source for domestic, industrial, and agricultural needs across Peru. Investments exceeding $4 billion in coastal irrigation allow farmers to cultivate vital exports like asparagus, chili peppers, and avocados, contributing significantly to the economy alongside staple crops like rice and sugar cane.
The Andean region boasts over 12,000 lakes and numerous streams, offering immense potential for energy generation.
This mountain system functions as a “water tower,” with dams like Mantaro providing 30% of Peru’s electricity.
Ranking third in hydro energy potential in South America, Peru has a capacity of 54.4 GW, well above its current demand of 4.5 GW, while also exploring wind, solar, and geothermal energy opportunities.
Peru, especially the Andean region, has a high degree of wild and cultivated genetic diversity and is one of the eight most important global centers of origin and diversity in agriculture and livestock as well as in plant and animal genetic resources amazing peru.
The potato, tomato, chili pepper, and quinoa are some of the treasures the Andes have provided the world. We need to remember that they are, before anything else, a cultural creation resulting from an accumulation of thousands of years of experiences through which Andean men and women learned how to understand, use, transform, and take advantage of their environment (Mujica, 1993).
As such, they tamed geography, plants and animals, time, and water, doing thus in a particular fashion based on coherent solutions to the challenges they faced from the setting in which they lived.
The National Biological Diversity Strategy (2001 Amazing Peru) states its main objective as “the conservation of biological diversity, sustainable use of its components, and the just and equitable participation in the benefits derived from the use of genetic resources.”
The 2009 – 2011 Amazing Peru – National Report of the State of the Environment claims that “the rural Peruvian population has made good use of its native biodiversity, respecting or intervening, in a relatively limited manner, in the majority of ecosystems.
Their wisdom has aided in the creation of new cultivated plant species required for their sustainable development.” Peru Travel Agency Operator.
the first human groups crossed into what is now Amazing Peru more than 10,000 years ago. These first settlers were descendants of Asian immigrants who had crossed the Bering Strait land bridge and spread across the entire North and South American continents.
They moved in small groups in search of food, which they found through hunting and gathering. Since they were nomads, their cultural trappings were simple.
Approximately 6,000 years ago, those ancient denizens supplemented their hunting/gathering with insipient forms of agriculture.
It took several millennia more to fully develop their agriculture systems as the mainstay for their food production.
This transition from the hunting – gathering and incipient farming to full blown agricultural production began about 4,000 years ago during the Mid Horizon or the Stabilization Period of Civilization, in which the Chavin culture flourished.
From that historical age onwards, food requirements were more reasonably satisfied through the cultivation of the land than they were in earlier time periods, which was reflected in rapid and sustained population growth as well as, to a certain degree, cultural development, a situation that brought about the rise of civilization to a level comparable to that of the ancient Old World cultures.
From the time that ancient Peruvians adopted the practice of farming as their main source of sustenance, the larger population was frequently confronted with an insufficient production of food.
A limited amount of arable land was the main reason for this problem, which was exacerbated on account of recurrent weather-related disasters, such as severe drought that brought with it famine.
The efforts to overcome this obstacle seem to explain the gestation process of Andean culture, its characteristics, and its subsequent development – Agency operator.
The territory encompassed by ancient Peru was always less than favorable for agricultural production.
On the western side of the Andes, the long yet confined and arid coastal fringe barely left room for fifty two narrow fertile valleys that are isolated and quite distant one from the other, with very limited rainfall and unpredictable river flows.
The Andes offer miniscule valleys or vertical terrain which is just as isolated between the complex succession of rugged mountain peaks and inhospitable plateaus.
The mountain farmers who settled the northern Amazonian Andes, at elevations between 2,000 meters and 3,000 meters, developed an Andean culture sui generis, given that they had to clear away the dense tropical vegetation that dominated that area.
The same process took place during the Incan Empire when the Incas migrated into the Vilcabamba region, home of Machu Picchu and other grand examples of monumental architecture, like Choquequirao trek, inca trail classic, salkantay trek, humantay lake trek, rainbow mountain trekking, ausangate trek, huchuy qosqo trek, lares valley trekking, etc, agency operator.
Hence, this explains the reason why the Incan culture, at the height of its splendor, required a much larger per capita territory than that of the ancient Euro-Asian cultures.
This vast area was, paradoxically, unable to produce the necessary food on account of its limited fertility, and it suffered recurrent natural weather disasters, such as those caused by the El Niño phenomenon.
Those reasons precisely explain why Andean inhabitants partially occupied the Amazonian Andes, moving eastwards to expand their agricultural frontier.
The stark contrast between the size of the Incan Empire and its limited agricultural potential caught the attention of the Spanish historians during the first years of the Conquest.
The Spanish missionary, Miguel Cabello Valboa, in his work Miscelánea antártica (1586) noted that this was a grave problem that caused severe overpopulation in the few habitable, “favorable and healthy” areas; he wrote further that “the untold number of people has, throughout the long years in this New World, propagated so much so that … there was no lack of men for the land, but a lack of land for the men.”
The most important trait of any mountain is its verticality, which is the reason why we can find different altitudinal tiers.
These levels are one part of the recipe for diversity, understood as the richness of life and its variants: plants, animals, and microorganisms, along with the genes they contain and their complex association in ecosystems that give shape to the natural landscapes.
Peru’s mountains are classified as tropical due to their latitudinal distribution (from 0°- 18° south latitude) and, as mentioned above, they are the sovereigns of the landscape and of cultures, expressions of which are the number of languages (52) and the massive variety of foods found in the country.
Nevertheless, the intertwining of so many colors and flavors and so much wisdom has turned Peru into a fragile crystal vessel that must be treated delicately: complex realities require complex solutions.
According to Jose Maria Arguedas, nearly all the world’s natural settings can be found in the Andes Peru.
That is one of the most important characteristics of tropical Andean ecosystems and, if we take into consideration their continuity to include the eastern and western slopes as well as their inter-Andean valleys, then 84 of the world’s 102 known life zones are found in Peru.
For the past ninety years, scientists have tried to classify the incredible diversity of ecosystems the country possesses, using different units: plant formations, life zones, natural regions, ecoregions, types of vegetation coverage, and fragile ecosystems, and attempting to find an order to the near entirety of the natural settings found in the country

An apacheta (cairn) at the Salkantay Pass along the Inca Trail to Machu Picchu. Trekkers leave these stone offerings as an act of beseeching the mountains for safe passage.
Pre-Hispanic cultures viewed the Andes as apus or gods, great rulers that form an amazing hierarchy: weather, soil, water, plants, animals, crops, livestock, culture, and history. Backbone, integrating factor, and expression of the character of our time: diversity. Cesar Vallejo, Peruvian poet, described the Andes in the following manner: “Andes of potato fields, quaternary maize, dilated peppertree, vicuñas, national descendants, guinea pigs, burning tomato peppers, christian logs, lichens, species in basalt formations, ground theoretical and practical, intelligent furrows, delicate archaeological dawns, climates met inside, waters with their deaf antiquity, intellectual field of cordillera in ascent in flagrante”.

Treck de Salkantay en 4 jours parfaitement organisé avec notre guide Herbert, alias Papas, à la fois très sympathique et professionnel. Super cuisinier (Jorge) également, pour des plats réconfortants après des heures de marche dans ces superbes montagnes ! Fabrice Pacitti2025-09-07Trustindex verifies that the original source of the review is Google. Nous avons fait la randonnée salkantay avec Okidoki et les bons conseils d'Alvaro qui nous a vraiment bien guidé pour bien choisir notre randonnée et c'était super l'organisation,la nourriture excellente avec notre chef cuistot Rojer , notre guide papas et notre groupe sans oublier l'organisation avec les sacs portés par les mules La beauté des paysages et terminer par le Machu Picchu c'était comme un rêve . Mille mercis pour ce moment inoubliable dans nos vacances. Alica Wenger2025-09-04Trustindex verifies that the original source of the review is Google. My partner and I booked the 3N/4D Salkantay Trek with Okiodoki and let me tell you – we had the best time. First of all: The Staff was amazing, very kind and super helpful. Alvaro (together with his wife Rosmary owners of Okidoki) replied within minutes to all our questions via whatsapp. A few days before the trek he welcomed us in his office, explained the tour in details and helped me getting over my fear, that the trek might be to hard for me (needless to say: all went perfectly fine and it wasn‘t as hard as I thought). They provided me with hiking poles (30 PEN for the 4 days) and in addition they lent me a daily backpack for free. All the material (duffle bag, sleeping bag, daily backpack) was in perfect condition and the sleeping bag really kept us warm during the cold night at the foot of the Salkantay. Our guide, Guilleromo, was probably the main reason why we had such good time. He timed the whole trip very well without being too pushy. That means, that everything went as it should and we always met our daily goal according to the timetable. Guilleromo is very kind and helpful. He made sure to keep us safe on the trip and inriched us with his profond knowlege of plants, the mountains, the indigenous community and the incas. Overall you could feel his passion for the nature, the mountains and the local cultur. We couln’d have wished for a better guide. Thank you so much Guilleromo! Our chef, Roger, prepared delicous meals, which were always right on time. The table was brautifully set and our special needs (vegetarisn or allergies) were always met. Also, the breakfast was a lot richer than I exprected and every day we got something new to try. Simon, the owner of the three mules, also was very sweet and kind and always a helping hand to Roger and Guilleromo. He made sure that our duffle bags arrived on time and we‘re still impressed how fast he managed to get from one campsite to the other! Second: compared to other tour companies, the groups at Okidoki are usually small. That allows you to get to know the participants in a more profond way. We happend to be a group of six people and the dynamic within the group was great. Third: the price-performance ratio is unbeatable. Of cours: don’t expect your trip to be luxurious. But keep in mind that you are doing a multiple day trip in the mountains and what they manage to offer, is already impressive. Particularly the first accomondation is very authentic and allows you to sleep under a sky full of stars with view on the salkantay. All accomondations are clean and you‘ll have a good sleep. If it‘s in your budget we would recommend to opt for the train to get back to cusco (costs arround 100 USD more). It only takes 4 hours (instead of 7h by van) and you won‘t have to walk additional 10km to the busstation after your visit to the Machu Picchu on your last day. After two hours train you‘ll get picked up by a van/bus to complete your journey back to Cusco. Overall we would recommend to book a trip with Okidoki for all reasons above and of course the amazing experience of the Salkantay!

Tout était parfaitement organisé : transports, repas, hébergement. Notre guide Guillermo connaissait très bien le terrain et a su nous partager sa passion avec enthousiasme. L’arrivée au Machu Picchu par la montagne restera pour nous un souvenir inoubliable - Je recommande! Juan Felipe Hedmont2025-08-24Trustindex verifies that the original source of the review is Google. Una experiencia excelente, This is the best agency to do whatever tour you want in Cusco and Machu Picchu, I did the Salkantay trial with guide, place to sleep and even cheff, amazing experience, totally recommended, thank you Alvaro, Victor and Ronald. Neil Chatterjee2025-08-14Trustindex verifies that the original source of the review is Google. Our experience with OkiDoki was excellent - Alvaro's organization and booking skills were incredible and we even got to do 2 circuits within Machu Picchu on the 2D/1N Inca Trail rather than just one. He even made it so that it was just us on the tour which made it extra special! Our guide, Alcides, was truly exceptional and made the experience 10x better and personalised. I would definitely try to request him if you are doing the Inca Trail with OkiDoki. The lunch we were provided was extremely comprehensive and included many many snacks, so I would not purchase any snacks of your own before going, but definitely bring water! The hotel we were booked in Aguas Calientes + the included dinner was so-so, but for the price you cannot really complain! The only downside we had was that Alvaro was sometimes not great at communicating and his emails sometimes made it seem as though he did not full understand what you were saying. You are also meant to pay the remaining cost (bar the deposit) in-person in cash and we organized this, but Alvaro then began hassling us and saying we had not paid in time despite having a discussion with him about when we were going to pay! This made one of our days in Cusco very stressful and we were rushing our day to get back in time to pay Alvaro and once we did he was not even there and made us wait an extra 2h to turn up and accept the payment. Overall, despite this slightly negative experience, I would still recommend OkiDoki to visit Machu Picchu because of their organization, knowledge of the laws and ticket booking systems, and their database of guides (go Alcides!!!!). Just make sure to complete the payment ASAP when you get to Cusco to avoid issues! Aubin Hansz-Mercier2025-08-14Trustindex verifies that the original source of the review is Google. Je ne peux que recommander, parti pour un treck de 5j pour Choquequirao. Un très bon guide, excellent cuisinier enfin bref, une équipe au top. La qualité de l'équipement fourni était très agréable aussi. Nous avons pu adapter le rythme à notre envie et nous avons visité le site avant tout le monde nous permettant d'être seuls! C'était magique Colette Guichard2025-08-04Trustindex verifies that the original source of the review is Google. Super expérience avec OkiDoki!! Mention spéciale à Guillermo, un guide en or, sympa, drôle et chaleureux. Merci aussi aux chefs qui nous ont régalés pendant ces quatre jours de trek, tout était au top, je ne peux que recommander OkiDoki (petit bonus : les skylodges pour voir les étoiles filantes depuis son lit ;) ! )
