The movement of a person or groups of persons who, predominantly for reasons of sudden or progressive change in the environment due to climate change, are obliged to leave their habitual place of residence, or choose to do so, either temporarily or permanently, within a State or across an international border. (International Organization for Migration. Glossary on Migration. 2019 https://publications.iom.int/books/international-migration-law-ndeg34-glossary-migration)
Note
Climate migration is a subcategory of environmental migration; it defines a singular type of environmental migration, where the change in the environment is due to climate change.

Ordination techniques summarize the data in a reduced number of dimensions while accounting for as much of the variability in the original data set as possible. As a result, they enable you to visualize relationships among sample units or with respect to individual variables. (Bakker, J. 2024. Applied Multivariate Statistics in R. https://uw.pressbooks.pub/appliedmultivariatestatistics/chapter/types-of-ordination-methods/ Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License)
Note
Statistical method. Do not confuse with "coordination" <c_50192>.
This term refers to a reading or value obtained with a SPAD (Soil Plant Analysis Development) chlorophyll meter, a device that non-destructively measures the amount of chlorophyll in plant leaves. These values indicate the plant's health and are used to optimize fertilizer use, especially nitrogen. (Adapted from Xiong, D., Chen, J., Yu, T. et al. SPAD-based leaf nitrogen estimation is impacted by environmental factors and crop leaf characteristics. Sci Rep 5, 13389 (2015). https://doi.org/10.1038/srep13389)
Chlorophyll meters are relatively simple proximal optical sensors that indirectly assess relative leaf chlorophyll content by measuring the differential absorbance and transmittance of different radiation wavelengths by the leaf. (de Souza R, Peña-Fleitas MT, Thompson RB, Gallardo M, Grasso R, Padilla FM. The Use of Chlorophyll Meters to Assess Crop N Status and Derivation of Sufficiency Values for Sweet Pepper. Sensors (Basel). 2019 Jul 4;19(13):2949. doi: 10.3390/s19132949. PMID: 31277420; PMCID: PMC6650809.)
In both the human rights and food security fields, the term “vulnerable groups” refers to groups of persons who, owing to physiological, socio-political and socio-economic reasons, cannot enjoy their human rights as fully as others or suffer from food insecurity or are at risk of becoming food insecure. (FAO. 2008. Right to Food Unit, Clarification of commonly used terms.)
Note
The term “disadvantaged groups” is sometimes used as a synonym. Vulnerable groups include indigenous peoples, ethnic, linguistic or religious minorities, elderly people, persons with disabilities, individuals living with HIV/AIDS and refugees and internally displaced people. Women and children are also often included as vulnerable groups. Other vulnerable groups, defined by livelihood characteristics, include urban poor, rural landless or smallholder farmers.
The lowering of the soil pH of the build-up of hydrogen and aluminium ions in the soil and the leaching of base cations such as calcium, magnesium, potassium and sodium. Soil acidification negatively affects soil fertility and compromises the production capacity of most agricultural soils. (FAO. 2022. The State of the World’s Land and Water Resources for Food and Agriculture – Systems at breaking point. Main report. Rome. https://doi.org/10.4060/cb9910en)
The maximum yield that can be achieved under specific agroecological conditions, combining agroclimatic potential yields with soil and terrain evaluations. It takes account of biophysical limitations such as temperature, moisture availability, soil type and slope, as well as specified levels of agronomic inputs and management practices. (FAO. 2025. The State of the World’s Land and Water Resources for Food and Agriculture 2025 – The potential to produce more and better. Rome. https://doi.org/10.4060/cd7488en)
Note
Attainable yield is distinct from potential yield as it integrates realistic constraints of soil and terrain, providing a more practical estimate of productivity for a given crop under defined conditions.
Digital finance refers to the delivery of traditional financial services digitally, through devices such as computers, tablets and smartphones. Use of technology within the finance industry, especially for consumers to electronically access financial services and accounts. (United Nations. 2023.

Biological corridor or biocorridor is the segmentation of the landscape that connects bio-centres and enables the migration of organisms and their communities, as well as the exchange of genetic data between them. (Republic of Albania. 2002. Law No. 8906, dated 6 June 2002, on protected areas. Assembly of the Republic of Albania. https://faolex.fao.org/docs/pdf/alb60472e.pdf)
Note
Increasingly, protected areas for biodiversity conservation are implemented following the so-called biological corridors or ecological networks approach, which reconciles biophysical and human perspectives and contributes to the integrity of the broader agroecological landscape.
