Production Approach

AbstractThis literature review deals with the understanding of ecosystem services related to the question of their applicability and appropriate methods for their valuation. We distinguish between ecological valuation methods that aim to assess the significance of landscape characteristics, conventional economic, i.e. monetary valuation and non-monetizing valuation or assessment. Ecological evaluation methods derive values by following a cost of production approach which neglects consumer preferences. Economic valuation methods focus on the exchange value of ecosystem services, i.e. they are based on consumer preferences, but do not adequately take into account the complex internal structure of ecosystems. We conclude that – from the view of implementation of ecosystem services for policy support and consulting – successful valuation approaches should particularly consider the relationships between economic, ecological and social aspects of ecosystem services’ provision.

Conservation Of Biodiversity

The paper emphasized the establishment of the Globally Important Agricultural Heritage Systems(GIAHS) and its purpose of dynamic conservation of biodiversity and culture in socioecological productionlandscapes and seascapes (SEPLS), particularly in satoyama landscapes in the Philippines, in Asia and theworld. Then, it outlines the next steps to be taken in order to attain sustainability and resiliency, namely;1) expansion of GIAHS sites and network through exploring Nationally Important Agricultural HeritageSystems (NIAHS) and Locally Important Agricultural Heritage Systems (LIAHS), 2) using internationalapproach and frameworks with customization as necessary even in working at the national and locallevels, 3) tapping leading universities to serve as focal points especially in the area of sustainability andresiliency research, economic and ecological valuation studies of ecosystem services, and 4) treatingGIAHS landscapes as a community and NOT as a commodity.Keywords: Ecology, human-nature interaction, Satoyama, socioecological production landscapes, resiliency,descriptive design, Philippines

And Function

Groundwater-dependent ecosystems (GDEs) are ecosystems that must have access to groundwater to maintain their ecological structure and function. Rapidly expanding numbers of humans are placing increased demands on groundwater for consumption, industry and agriculture. These demands alter groundwater regimes of GDEs that have evolved over millennia, resulting in the degradation of ecosystem health. As a consequence, the goods and services (ecosystem services) that GDEs provide for humans, which include food production and water purification, are at serious risk of being lost. Effective management of GDEs and their ecosystem services requires prioritisation of the most valuable ecosystems, given that increasing human demands and limited time and money preclude complete protection of all GDEs. Here, we provide an eight-step method for the valuation and initial prioritisation of GDEs. The proposed methodology improves on previous, primarily subjective methods for the valuation of GDEs by employing both economic valuation of the ecosystem services provided by GDEs, and ecological valuation of significant environmental attributes of GDEs. We apply the eight-step method to a hypothetical case study in order to demonstrate its applicability to a catchment containing a range of GDEs of different sizes, each possessing its own suite of threatened taxa. The major benefit of the valuation methodology presented here is that it can be used at three levels of complexity: (1) a full-desktop study, (2) a semi-desktop study requiring stakeholder consultation, and (3) a full field-based study, according to the time and money available for initial prioritisation efforts.

This case explores the Methow Beaver Project (MBP), an ambitious experiment to restore beaver (Castor canadensis) to a high mountain watershed in Washington State, USA. The Pacific Northwest is already experiencing weather regimes consistent with longer term climate projections, which predict longer and drier summers and stronger and wetter winter storms. Ironically, this combination makes imperative more water storage in one of the most heavily dammed regions in the nation. Although the positive role that beaver can play in watershed enhancement has been well known for decades, no project has previously attempted to re-introduce beaver on a watershed scale with a rigorous monitoring protocol designed to document improved water storage and temperature conditions needed for human uses and aquatic species. While the MBP has demonstrated that beaver can be re-introduced on a watershed scale, it has been much more difficult to scientifically demonstrate positive changes in water retention and stream temperature, given hydrologic complexity, unprecedented fire and floods, and the fact that beaver are highly mobile. This case study can help environmental studies students and natural resource policy professionals think about the broader challenges of diffuse, ecosystem services approaches to climate adaptation. Beaver-produced watershed improvements will remain difficult to quantify and verify, and thus will likely remain less attractive to water planners than conventional storage dams. But as climate conditions put additional pressure on such infrastructure, it is worth considering how beaver might be employed to augment watershed storage capacity, even if this capacity is likely to remain at least in part inscrutable.

The aim of the article was to defi ne the role of the radioactive environment contamination in the formation of ecosystem services strategy. Methods. Monographic, systemic and structural, factor analysis, abstract and logical research methods have been used. The data from the State Statistics Service of Ukraine, the Ministry of Agrarian Policy and Food of Ukraine, the Ministry of Ecology and Natural Resources of Ukraine, materials of scientifi c researches, international materials and reports and other literary sources on the issues investigated have been used as an information base. Results. Retrospective analysis of sources and state of radioactive eco- systems contamination was conducted and the priority steps in developing the concept of ecosystem services in conditions of radiation contamination were found. Conclusions. The current socio-ecological paradigm of the transition from environmental use to environmental management should be refl ected in the relevant envi- ronmental management mechanisms. Currently, when assessing the state of ecosystem services in Ukraine and worldwide one must take into account the changes in food demand of residents of radioactively contaminated areas, the exploitation of radioactively safe ecosystems growth, their overload and degradation. All of this re- quires an inventory of ecosystem services by type, region, consumers, etc. and the formation of a state register of ecosystem services with a clear assignment of area of responsibility for appropriate natural ecosystems. This will help to make the economic evaluation of different ecosystem services and mechanisms of charges for ecosystem services.
