The purpose of this study is to understand the impact mechanism of grassland transfer on herders' production behaviour in pastoral areas. The impact of grassland transfer on herders' livestock production and grazing intensity is quantified.

Using the survey data collected for 356 herder households from Inner Mongolia and Gansu, China, quantile regression is employed to assess the heterogeneous effects of grassland transfer on livestock production and grazing intensity. To correct the potential self-selection bias of grassland transfer, the propensity score matching technique is used.

Results show that labour, percentage of livestock income and livestock stock are the main factors affecting herders' choice to transfer grassland. The positive effect of grassland transfer on livestock numbers on behalf of those who rented additional grassland is statistically significant but declines with livestock numbers. The sustainability-enhancing effect of grassland transfer on grazing intensity is significant, and the effect becomes larger amongst herder households with higher grazing intensity. The analysis on the impact mechanism shows that grassland transfer significantly promotes the adoption of sustainable grazing modes, such as rotational and seasonal rest grazing, which in turn increases herders' livestock numbers and decreases grazing intensity.

Few studies have empirically analysed the influence of grassland transfer on livestock numbers and grazing intensity. This study fills this gap by employing a quantile regression to assess the heterogeneous effects of grassland transfer on livestock numbers and grazing intensity, while accounting for self-selection bias. In addition, the authors have examined the influencing mechanisms under which grassland transfer impacts on livestock numbers and grazing intensity.

The Portuguese montado is a particular land use system, characterized by the combination, in the same area, of the forestry and the grazing components interrelating with each other, in large-scale farm units. Mostly, this system is acknowledged due to its specific landscape character, in a savanna-like phisionomy, with changing densities along a continuous tree cover of holm and cork oaks and grazing in the under cover. The montado is a production system, and its extensive character and particular pattern makes it possible to support a multitude of ecosystem goods and services nowadays valued by society. Nevertheless the system is threatened and the resulting landscape is under strong reduction in the last decades. This paper shows the dimension of the ongoing reduction, for the whole region of Alentejo, since 1960 and up to now. And furthermore, based on a survey to land managers of montado in a Natura 2000 site, it shows how the land management options for the most are still focusing on production and productivist ideals, even when keeping a multifunctional system. These orientations do not result in a radical replacement of the system, and therefore the illusion is kept that the multifunctionality is mantained – but progressively the system loses its balance and the tree cover decays in such a way that the montado disappears. This unique landscape is thus under severe threat. The paper ends with a discussion on the urgent need for integrated policy goals and tools for the montado as a system, and for much more colaboration with the land managers in order to strength the multifunctionalty relevance and support a novel attitude replacing the productivist concept of farming, misleading in the context of this system.

To achieve the dual goals of decarbonization and food security, this paper examines China's carbon footprint reduction in 2050 based on current mitigation strategies.

Considering publications as featured evidence, this study develops an investigation of agricultural decarbonization in China. First, the authors summarize the mitigation strategies for agricultural greenhouse gas (GHG) emissions in the existing literature. Second, the authors demonstrate the domestic food production target in 2050 and the projection target's projected life-cycle-based GHG emissions at the commodity level. Lastly, the authors forecast China's emission removal in the agri-food sector in 2050 concerning current mitigation strategies and commodity productions. The authors highlight the extent to which each mitigation strategy contributes to decarbonization in China.

Practices promoting sustainable development in the agri-food sector significantly contribute to GHG emission removal. The authors find mitigation strategies inhibiting future GHG emissions in the agri-food sector comprise improving nitrogen use efficiency in fertilizers, changing food consumption structure, manure management, cover crops, food waste reduction, dietary change of livestock and covered manure. A 10% improvement in nitrogen use efficiency contributes to 5.03% of GHG emission removal in the agri-food sector by 2050. Reducing food waste and food processing from 30% to 20% would inhibit 1.59% of the total GHG emissions in the agri-food sector.

This study contributes to policy discussions by accounting for agricultural direct and indirect emission components and assessing the dynamic changes in those related components. This study also extends existing research by forecasting to which extent the decarbonization effects implemented by current mitigation strategies can be achieved while meeting 2050 food security in China.

The purpose of this study is to evaluate the vulnerability of the important rangeland shrub, Atriplex leucoclada (Boiss) to both climate change and livestock grazing, within the Syrian rangelands as a representative landscape type of West Asia.

Ecologically based quantitative niche models were developed for both shrub species using maximum entropy and 13 spatially explicit GIS-based layers to predict current and future species distribution scenarios. Climatic variables varied over time in line with the predictions created from the HADCM3 global circulation model.

Results indicate that with grazing and climate change, the distribution of A. leucoclada will be reduced by 54 per cent in 2050, with the mean annual and minimum temperatures of the coldest month having the highest contribution in the model (28.7 and 21.2 per cent, respectively). The contribution of the grazing pressure, expressed by the overgrazing index, was estimated at 8.2 per cent.

These results suggest that the interaction of climate and increased grazing has the potential to favor the establishment of unpalatable species, while reducing the distribution of preferred plant species on western Asia rangelands.

The contradiction and conflict between grassland conservation and economic development are prominent in the Qinghai–Tibet Plateau (QTP) with its fragile environment and ecosystem. How to promote sustainable grazing in the plateau without hurting the economic welfare of local residents is a key challenge facing the Chinese government. This study explores the potential of market-based grassland conservation policies by evaluating consumer preferences and valuations for forage–livestock balance certification labeled yak products.

This study adopts a choice experiment with four attributes of yak meat, including forage–livestock balance certification, feeding type, age at slaughter and price. A sample size of 2,999 respondents from Beijing, Shanghai, Wuhan, Guangzhou and Chengdu was collected by a professional online survey company.

The result reveals that urban Chinese consumers are willing to pay highest price premiums for forage–livestock balance certified yak meat, followed by grass-fed claim labeled meat. Consumers on average place negative valuations for grain-fed claims, meat from yak slaughtered above 2 and 4 years old. Heterogeneous analysis indicates that individuals who are female, younger, married, and better educated, and with above median income, Tibet travel or yak consumption experience, are more receptive to the forage–livestock balance certification.

It is the first study to explore demand-driven mechanisms for grassland conservation by focusing on consumer valuation for the forage–livestock balance certification.

The purpose of this paper is to assess the impact of human factor on ecological conditions of Moroccan cedar forest with a view to drawing out implication for sustainable forest management. The study is set against the backdrop of the global depletion of natural capital in a rare axis which, if not brought under an integrated sustainability purview, might lead to the extinction of this quickly receding natural resource.

Data for this research are mined from publicly held databases but processed through a time series regression analysis in a way that measures variations in ecological/environmental variables.

Findings reveal that changes in precipitation and temperature account for a small but significant amount of variation during the period 1940-2006. However, most of the decline is attributable to human activities such as overgrazing and illegal logging. These are having far-reaching implications for forest conservation management.

Human agency, more than any effect of nature, is chiefly responsible for the unsustainable development in this sphere of natural capital. Whilst this may not altogether constitute new knowledge, the paper highlights ambivalent positions that both promote and constrain efforts to sustain cedar forest. Its novelty lies not only in the empirical substantiation it affords but also in ferreting out strategic initiatives to dis-incentivise unsustainable exploitation of this important aspect of natural capital.

This research examined the impacts of diversified income from trading caterpillar fungus on pastoral households' livestock production and income. The specific objectives were to identify the main factors underlying participation in caterpillar fungus trade and to explore the impacts of a diversified income from trading fungus on livestock production activities and income.

Data were collected from a pastoral household survey (n = 503) in five Tibetan Autonomous Prefectures. The authors employed propensity score matching (PSM) procedures to estimate the effects of participation in trading caterpillar fungus.

Pastoral households participating in caterpillar fungus activities maintain smaller herds, sell fewer animals for profit, slaughter more livestock for family consumption and experience fewer livestock deaths compared to nonparticipants. There is also some evidence that pastoral households participating in caterpillar fungus activities have a higher annual income compared to nonparticipants.

A direct measure of grassland degradation was not included due to the data limitation. The estimated average treatment effects could differ under different observed households' characteristics.

This study fills a gap in the literature on the impacts of diversified income on livestock production activities. The authors provide a new perspective on the controversy over the extraction of caterpillar fungus. This study contributes to exploring the dual role of income diversification in addressing poverty and grassland resource degradation for Tibetan pastoral communities.

The purpose of the paper is to show that land degradation and desertification are threatening the livelihood of more than a billion dryland inhabitants. The paper aims to present traditional and novel approaches for sustainable agricultural exploitation of the arid drylands in Southern Israel and similar climatic zones, and their potential for rehabilitating degraded drylands and increasing agricultural productivity.

The paper analyses the current agricultural activities on the Abu Rabia farm as well as developing experimental approaches and discusses the expected impact on ecological, economic and social sustainability.

The farm investigated consists of about 120 hectares of semi‐desert land 30 km east of Beer Sheva, divided about 50:50 between rocky hill country and plains with deep loess soil. The area receives an average 200 mm of rain per year. The land is used for raising livestock (about 120 head of sheep and goats), wheat cultivation on high quality soil, and agroforestry, mainly olive cultivation in terraces designed to collect runoff water of seasonal streams. These activities provide a basic income and cover a significant amount of the families' food requirements, but can not provide a full income for a family head in a developed country like Israel. Improving the quality of the grazing land by silvipasture, further investments into high value dryland tree crops and simultaneous production of wood for industry and energy can dramatically increase the farm's income, its resilience to drought and ecological sustainability.

This analysis demonstrates the potential of dryland agroforestry for sustainable development while solving a number of economic and social problems of poor dryland inhabitants, and it contributes to fighting desertification and global warming.

This case study demonstrates that sustainable dryland exploitation by agroforestry can establish significant agricultural production potentials on marginal lands often considered worthless. Because of the establishment of significant and permanent carbon sinks, carbon trading may be mobilized to cover the required investments creating a classical win‐win situation.

Plant cover was measured for three years in the rangelands of Psilorites mountain of Crete, located at a mean altitude of 1,200m and overgrazed by sheep and goats from May to October. Rangelands consist of phryganic ecosystems dominated by dwarf shrubs, often subjected to occupational burning, and secondarily by grasslands. Herbaceous cover was significantly lower in the overgrazed than in the protected sites, but woody cover was higher unless the dwarf shrubs were palatable to animals. When overgrazing was combined with occupational burning then both plant groups were reduced with total cover reaching threshold values for potential soil erosion and desertification. On the contrary, no substantial differences were found between years indicating that overgrazing and burning were much more important than environmental changes. The results suggest that plant cover is an effective tool for monitoring the impact of pastoral activities on rangeland vegetation and therefore on desertification of mountain Mediterranean rangelands.

The purpose of this paper is to test hypotheses about the effects of economic and weather factors on the inventories of cattle, sheep and goats in Inner Mongolia Autonomous Region (IMAR).

An equilibrium displacement model of livestock products is combined with an inventory relation proposed by Rucker et al. (1984) to deduce hypothesis about the effects of expected price and feed costs, weather, and supply and demand shifters on herd size. Dynamics are incorporated using the partial adjustment and adaptive expectations models originally proposed by Nerlove (1956). The hypotheses are tested using both the structural equations implied by the model, and the reduced form.

Results suggest livestock inventories in IMAR in general are more responsive to weather conditions than to economic conditions. This is especially true for cattle and sheep, where isolated 1 percent changes in weather variables, namely precipitation and radiation, were found to have a much larger effect on inventory than isolated 1 percent changes in expected price and forage costs. The effects of the weather variables, moreover, were found to be different for goats than for cattle and sheep, with goat numbers decreasing with improvements in weather, and cattle and sheep numbers increasing. This suggests herders respond to poor weather in part by substituting goats for cattle and/or sheep. Price was found to have a negative effect on cattle inventory, and no effect on sheep and goat inventory. Forage costs were found to have a positive effect on cattle and sheep inventories, and no effect on goat inventory. These results suggest policies to protect grassland by controlling inventory levels must be designed carefully if they are to be effective.

The paper makes a methodological contribution in that the livestock inventory relation proposed by Rucker et al. (1984) is extended to include supply and demand shifters for livestock products in a partial-equilibrium setting where the industry in question is a net exporter of livestock products. The paper makes an empirical contribution in that additional evidence is provided on the role that price plays in inventory behavior.
