Action versus Result-Oriented Schemes in a Grassland Agroecosystem: A Dynamic Modelling Approach

Effects of agri-environment schemes (AES) on biodiversity remain controversial. While most AES are action-oriented, result-oriented and habitat-oriented schemes have recently been proposed as a solution to improve AES efficiency. The objective of this study was to compare action-oriented, habitat-oriented and result-oriented schemes in terms of ecological and productive performance as well as in terms of management flexibility. We developed a dynamic modelling approach based on the viable control framework to carry out a long term assessment of the three schemes in a grassland agroecosystem. The model explicitly links grazed grassland dynamics to bird population dynamics. It is applied to lapwing conservation in wet grasslands in France. We ran the model to assess the three AES scenarios. The model revealed the grazing strategies respecting ecological and productive constraints specific to each scheme. Grazing strategies were assessed by both their ecological and productive performance. The viable control approach made it possible to obtain the whole set of viable grazing strategies and therefore to quantify the management flexibility of the grassland agroecosystem. Our results showed that habitat and result-oriented scenarios led to much higher ecological performance than the action-oriented one. Differences in both ecological and productive performance between the habitat and result-oriented scenarios were limited. Flexibility of the grassland agroecosystem in the result-oriented scenario was much higher than in that of habitat-oriented scenario. Our model confirms the higher flexibility as well as the better ecological and productive performance of result-oriented schemes. A larger use of result-oriented schemes in conservation may also allow farmers to adapt their management to local conditions and to climatic variations

Agri-Environmental Policy Measures in Israel: The Potential of Using Market-Oriented Instruments

This paper examines the possibilities of developing agri-environmental policy measures in Israel, focusing on market-oriented instruments. A conceptual framework for developing agri-environmental policy measures is presented, first in very broad lines (mandatory regulations, economic instruments and advisory measures) and subsequently focusing on economic instruments, and specifically, on market-oriented ones. Two criteria of choice between the measures are suggested: their contribution to improving the effectiveness of the policy; and the feasibility of their implementation. This is the framework used for analyzing agri-environmental measures in Israel. Israel currently implements a mix of mandatory regulations, economic instruments and advisory measures to promote the agri-environment. The use of additional economic instruments may improve the effectiveness of the policy. When comparing the effectiveness of various economic measures, we found that the feasibility of implementation of market-oriented instruments is greater, due to the Israeli public’s preference for strengthening market orientation in the agricultural sector. Four market-oriented instruments were practiced in a pilot project conducted in an Israeli rural area. We found that in this case study, the institutional feasibility and acceptance by stakeholders were the major parameters influencing the implementation of the market-oriented instruments, whereas the instruments’ contribution to enhancing the ecological or economic effectiveness were hardly considered by the stakeholders as arguments in favor of their use

Does livestock predation reflect in negative local perceptions of Ethiopian wolves in South Wollo?

The conservation of rare and endangered carnivores in human dominated landscapes is particularly challenging when predators are perceived as a threat to livestock. This study verifies whether the human perception of Ethiopian wolves as predators of livestock accurately reflects the actual damage done by this specialist predator of highland rodents. With that purpose, we quantified the contributions of prey species, including livestock, to the diet of Ethiopian wolves by analysing 118 scats. We then compared them to the reported livestock losses and attitudes in 300 households surrounding wolf habitat in the highlands of South Wollo in north Ethiopia. We found 10 prey species, totalling 222 prey occurrences in the study sample. The most common prey were diurnal rodents, with 79.2% of all prey occurrences. Only 5.4% were livestock (sheep) remains, a result similar to that obtained in other wolf populations. The proportion of households reportedly affected by Ethiopian wolf predation was relatively low (17%), and these households lost an average of 1.0 sheep per year over the previous five years. Even though the proportion of households affected by livestock predation was relatively low, 88% of the households that reported losing sheep to Ethiopian wolves had a negative perception of the species, compared with only 9% of the households unaffected. Clearly current levels of livestock predation in South Wollo lead to widespread negative attitudes among the people affected, an emerging problem that requires the attention of conservationists and wildlife authorities
