Previous studies have described complementary feeding practice using single indicators but a combination of indicators is needed to better explain the role of complementary feeding practices in child growth.
More specifically, future research will need to discover whether there is a unique indicator or a combination for a single tree species using remote sensing data, or if we are limited to distinguishing between species using a more locally tailored approach.
In the Sahel, the bad health indicators reflect a combination of converging factors: lack of health centres, skilled staff, and resources; bad quality of care delivery, corruption, mismanagement; absence of any social security or meaningful commitment to the worst-off; growing competition from drug peddlers on one side, from private clinics on the other.
Socioeconomic status may affect health in a variety of ways [ 30], including adverse environmental exposures, and it is unlikely that specific indicators, or even a combination of indicators, can take into account all of its impact.
It is based on a combined air quality indicator, which is a combination of information about the contribution to air pollution from NOx, sulfur dioxide, particulate matter and benzene.
Additionally a new R-factor is proposed as a rainfall indicator, which is a combination of the 1 hour rainfall and cumulative rainfall before the landslide event and the annual rainfall.
We isolated and analyzed the influence of the topography on the triggering of shallow landslides in catchments with almost identical hydrological and geological conditions and propose a new T-factor as a topographical indicator which is a combination of the slope angle, the upslope contributing area, the cross-section, and the free-face of a (potential) shallow landslide.
The boundaries for fulfillment conditions are obtained from several references (see Table 3, column 6), such as national/local regulation (e.g., indicator concerning investment costs), a combination of survey and stakeholders' opinions (e.g., indicator concerning water consumption), and own observations of the author (e.g., indicator concerning technical skill).
We do this because some of the chronologies that we consider may be tailored to a single indicator rather than being a combination of dates as we have proposed.
Therefore it seems difficult to use this indicator alone or in a combination of 2 syndromes.
