4. Population-environment linkages and population programmes

UNFPA has declared its interest for supporting studies of selected aspects of population-environment linkages, namely:

* interactions between population growth or distribution and priority environmental problems (including desertification, deforestation, water pollution, overuse of lands, urban overcrowding etc.);

* the consequences of deteriorating environments on infant mortality, maternal morbidity, food security, employment, migration etc.;

* women as "agents and change" and protectors of the environment;

* the interaction of population factors with other factors of environmental change;

* the population-supporting capacity of agricultural lands in developing countries, particularly in areas of low food security;

* methods to integrate population concerns in planning for sustainable development;

* the problems of especially vulnerable groups (children, landless families, indigenous peoples etc.) at the local level;

* the adaptation of existing methodologies to better conceptualize and communicate population-environment problems for use in IEC activities.

In this context "country case studies are to be given special attention because they afford the opportunity of examining linkages between population and the environment in different contexts" with regard to political, natural resources and economic circumstances.

Another relevant source of priorities is the Agenda 21 (UN, 1993). The focus is on "Developing and disseminating knowledge concerning the links between demographic trends and factors and sustainable development", where the following activities are proposed:

(a) "Identifying the interactions between demographic processes, natural resources and life support systems, bearing in mind regional and subregional variations deriving from, inter alia, different levels of development";

(b) "Integrating demographic trends and factors into the ongoing study of environmental change [...] first, to study the human dimensions of environmental change and, second, to identify vulnerable areas";

(c) "Identifying priority areas for action and developing strategies and programmes to mitigate the adverse impact of environmental change on human populations, and vice versa".

As we have seen, the countries of central and south Asia are widely affected by environmental problems, many of which are ascribable at least in part to population factors. There is, therefore, ample scope for activities along these lines, for which UNFPA support could be considered.

A first type of activities, aiming at improving the understanding of processes at work, consists in retrospective studies, such as:

1 - Assessing the role of population dynamics and other factors with respect to prevailing trends in water supply issues, land degradation, deforestation.

2 - Assessing the impact of urban expansion on the state of natural resources (cropland, forests, water).

3 - Assessing changes in the quality of urban environment (access to water and sanitation, infrastructure, equipment) and assess their reciprocal relationships with the dynamics of human settlements.

Next come policy-relevant studies. In this connection an important prerequisite is worth mentioning, namely:

4 - Advocacy, i.e. the use of information techniques to raise the awareness of government and relevant public agencies staff regarding concrete, priority reciprocal linkages of population dynamics and environmental change at the national and sub-national levels (in light of the knowledge gained through the above activities), and achieve a clear recognition of the need to develop policies that take those linkages into account.

As for activities more practically oriented towards policy formulation, some are geared to establish necessary information bases and current diagnoses, such as:

5 - Based on country characteristics, identify specific environmental indicators integrating population dimensions. Look specifically into the feasibility of spatially disaggregated indicators. Set up data collection and processing systems. Where feasible, build retrospective time series for these indicators as a starting point for analysis.

6 - Assess current dimensions of population pressure on water resources: count population by watershed area, assess broad patterns of use by sector.

7 - Identify the vulnerable populations with regard to specific environmental issues, e.g. pollution, water supply problems, deforestation. (Even in the case of a localized problem, those populations may be quite different from those living in the area where the problem arises.)

Other studies are more of the "policy study" type in the strict sense, i.e. geared to assess the implications of alternative courses of action or alternative scenarios regarding exogenous variables; for instance:

8 - Project population impact on various environmental goods (e.g. cropland, building areas, water resources, forests) based on scenarios of population growth, urbanization, consumption patterns. Illustrate potential differences arising from alternative demographic scenarios.

All these activities are meant to produce utilizable results in the policy making context (i.e. the second programme area of the Agenda 21, namely the formulation of integrated environment and development policies taking into account demographic trends and factors). Specific assistance for the latter purpose will often be valuable, mainly in the form of:

9 - Capacity building--e.g., interdisciplinary workshops making use of practical exercises in formulating environment and development strategies.

10 - Support to monitoring activities, including the methodological level (design of indicators, problems related to the collection of data on population and environment in censuses and other statistical operations).

Finally, it is worth mentioning again that the linkages between population and environmental change can be a valuable addition to traditional population education themes:

11 - IEC activities addressing the general public could derive arguments inter alia from those linkages, especially where the impact of environmental degradation on people's health and living conditions is more acutely felt. Field experiences in communication campaigns focused on such themes, built upon assessments of the people's perceptions regarding environmental change, its causes and consequences, can be utilized with profit in new contexts.

Programming at the country level should always include a systematic assessment of needs for these various kinds of inputs to country policies. In addition, there would be great value in undertaking country activities, such as those suggested above, in a coordinated manner in groups of countries that share the same issues and therefore can benefit both from one another's experience, both in data collection/analysis and in applying thematic knowledge to policy making.
