Abstract
Research Highlights: the wide variety of multispectral sensors that currently exist make it possible to improve the study of forest systems and ecosystem services. Background and Objectives: this study aims to analyze the current usefulness of remote sensing in forest management and ecosystem services sciences, and to identify future lines of research on these issues worldwide during the period 1976–2019. Materials and Methods: a bibliometric technique is applied to 2066 articles published between 1976 and 2019 on these topics to find findings on scientific production and key subject areas. Results: scientific production has increased annually, so that in the last five years, 50.34% of all articles have been published. The thematic areas in which more articles were linked were environmental science, agricultural, and biological sciences, and earth and planetary sciences. Seven lines of research have been identified that generate contributions on this topic. In addition, the analysis of the relevance of the keywords has detected the ten main future directions of research. The growing worldwide trend of scientific production shows interest in developing aspects of this field of study. Conclusions: this study contributes to the academic, scientific, and institutional discussion to improve decision-making, and proposes new scenarios and uses of this technology to improve the administration and management of forest resources.
Highlights
IntroductionApproximately 5 billion people are considered to live in cities
The findings obtained are valuable for a group of actors involved in scientific research on remote sensing applied in the forest management to optimize ecosystem services, and who require an examination of past and future information, such as engineers, investment analysts, academics, researchers, research institutions, universities, government agencies, suppliers of materials and services, among others
The objective of this study was to analyze the evolution of scientific production and research trends worldwide, over the last four decades, on remote sensing applied in the forest management to optimize ecosystem services
Summary
Approximately 5 billion people are considered to live in cities. The urban population is expected to reach 6.5 billion within a decade [1,2]. This urban growth will affect terrestrial ecosystems and will produce an increase in demands on the services they provide [3]. The establishment of forest ecosystems requires a minimum of conditions that allow the growth of trees. Forest conservation is vital for its positive effects against global warming and the protection of biological diversity and indigenous peoples.
