Cultural management in ecological practices

26/10/2024 Go to Evidence

A comparative study conducted by the University of Costa Rica (UCR) analyzes agroecological practices in Nicaragua, Costa Rica, and Panama, highlighting the role of cultural agricultural management and ancestral knowledge in farm sustainability. Through interviews and field observation, it identifies key categories such as soil fertility, productive diversification, biological control, and resource conservation. The article shows how peasant traditions strengthen resilience, productive autonomy, and local innovation, driven by cooperation networks between farmers, NGOs, and international agencies.

Red macroalgae for sustainable agriculture

02/07/2024 Go to Evidence

The article analyzes the biotechnological potential of the red macroalgae Kappaphycus alvarezii, Acanthophora spicifera, and Hypnea spinella as an ecological alternative for sustainable agriculture in Ecuador. It highlights their bioactive compounds—polysaccharides, amino acids, polyphenols, and phytohormones—which can replace synthetic fertilizers and pesticides. It also highlights that their cultivation does not compete with land or require fresh water, offering a viable option for reducing agrochemicals, improving plant productivity, and strengthening the coastal economy through the use of sustainable marine resources.

Silvopastoral transitions in Latin America

18/06/2024 Go to Evidence

Transitions to silvopastoral systems increase resilience, productive stability and ecosystem services in degraded soils, but reduce biodiversity by replacing native ecosystems (Picasso and Pizarro, 2024).

Perches and shelters for forest restoration

05/06/2024 Go to Evidence

In montane forests in Bolivia, the installation of bird perches and bat shelters increased seed rain and seedling density by up to 3-5 times compared to degraded areas dominated by ferns.

Agroecological practices in Cuba

30/06/2023 Go to Evidence

Study conducted by the National Institute of Agricultural Sciences (Cuba) between 2020 and 2022, with support from Swiss Development Cooperation (SDC). It evaluates the effect of applying agroecological practices on three farms in the municipality of Jaruco, Mayabeque province, which are transitioning to sustainable systems. Through interviews and participant observation, the impact of the use of bioproducts, organic fertilizers, varietal diversification, and biological control on the yields of crops such as sweet potatoes, beans, and corn was analyzed, showing increases of 20% to 70%. The results show improvements in the productivity, resilience, and sustainability of agroecosystems, contributing to local food security and sovereignty.

Diagnosis of Andean livestock farming in Peru

29/12/2022 Go to Evidence

Peru's Andean livestock system is highly heterogeneous structurally, with a predominance of small producers, low productivity and limited access to technical services, which requires differentiated policies by type of producer (Quispe et al., 2022).

Biodiversity islands in agricultural landscapes of

23/04/2022 Go to Evidence

In the Ucayali Amazon, forest fragments (biodiversity islands) within agricultural landscapes are essential to conserve dominant species, maintain connectivity and design conservation strategies in territories already transformed by cattle ranching and monocultures. (Clavo & Vela, 2022).

Remote sensors in banana cultivation

11/03/2022 Go to Evidence

The study presents a review of the use of remote sensors in agriculture, with an emphasis on their applications for banana cultivation (Musa AAA) in Costa Rica and other tropical regions. It evaluates three main areas: the delimitation of cultivated areas, the estimation of productivity, and the diagnosis of diseases. It analyzes the advantages of using satellite imagery, synthetic aperture radar (SAR), and drones (UAVs) in agricultural monitoring, highlighting their accuracy (up to 95%) in identifying plantations and detecting diseases such as black Sigatoka and Fusarium wilt. The study demonstrates the potential of these technologies to improve agricultural planning, environmental management, and phytosanitary prevention.

Sustainable agriculture with associated crops

08/01/2022 Go to Evidence

The article analyzes crop association as an alternative for the development of sustainable agriculture in Latin America. Through a review of 88 studies, it shows that polyculture, agroforestry, and silvopastoral systems improve productivity, profitability, and climate resilience compared to monocultures. It highlights the benefits for soil fertility, biodiversity conservation, and climate change mitigation, proposing this practice as a comprehensive path toward agricultural and food sustainability in rural farming contexts.
