Socioeconomic Factors Affecting Farmers’ Perceptions of Land Degradation and Stonewall Terraces in Central Palestine 总被引:1,自引:0,他引:1
Land degradation by soil erosion is a socioeconomic and environmental problem facing many developing countries. Application
of stonewall terraces for soil moisture conservation is vital to reducing the environmental impacts of this phenomenon. To
this end, a field plot experiment was conducted in the study area along with the use of a closed-ended questionnaire. The
object of the experiment was to study the socioeconomic impacts of soil erosion on local farmers and their adoption of the
stonewall terrace technique. The study showed a higher net profit in areas that had implemented terrace conservation practices
than in areas that had not (i.e., 3.5 to 6 times higher net profit). Correlation analysis indicated that the farmers’ perceptions,
land ownership, and geomorphology were significantly related to the farmers’ incentives and willingness to adopt terraces
as soil conservation measures (P < 0.05), although the correlations were negative. Smallholder farmers (52% of the interviewed farmers) were involved in the
sale of the agricultural land for urban uses, largely because of the high price and immediate returns offered. However, the
associated land use changes warrant greater involvement of both the private and public sectors. This cooperation may be accomplished
through the introduction of a long-term agricultural loan system and the development of proper legislation accompanied by
a comprehensive and durable infrastructure and service system with the goal of reducing the negative impact of land use changes
and encouraging sustainable use of resources. 相似文献

Biodiversity Conservation,Ecosystem Services and Livelihoods in Tropical Landscapes: Towards a Common Agenda 总被引:1,自引:1,他引:0
Trade-offs between ecosystem conservation and agricultural production can more easily be addressed by shifting the view from
the plot scale to the scale of the landscape and integrating biodiversity friendly land use systems into development strategies.
The provision of ecosystem services such as watershed protection and carbon sequestration by natural and complex agro-ecosystems
can play an important role in making such integrated landscape approaches viable. This special issue brings together papers
that were presented at a symposium on agroforestry and landscape scale conservation at the Second World Agroforestry Congress
in Nairobi in August 2009. It is divided into two sections focusing on: (1) the biological mechanisms and implications of
landscape scale conservation strategies as influenced by land use, especially agroforestry; and (2) the economic drivers and
public policies that determine to a large extent the success of agroforestry-based landscape conservation strategies. The
contributions provide evidence both for the potential and limitations of agroforestry in landscape scale conservation and
development strategies and highlight the importance of economic incentives and policies to promote integrated landscape solutions.
This introductory paper summarizes and discusses the contributions and concludes with policy recommendations and research
needs. 相似文献

Practitioners and stakeholders involved in environmental and risk assessment and decision-making efforts have access to a
growing list of policies and guidance for implementing good process. The advice is often general. There is little understanding
of how situation specific features are relevant in new circumstances. In a series of ten case studies we investigated how
people’s (a) perceptions of the context, (b) preferences for outcomes, and (c) affiliations, experiences and motivations are
related to their preferences for process features in a particular situation. The cases are in three policy areas: watershed
management, forestry management, and clean-up and public health management of radioactively contaminated sites. We conclude
this paper with a discussion of how the results can inform process design. Process design should be based on a diagnostic
approach that specifically assesses relevant situational characteristics. 相似文献

Public debate on acceptable farm animal husbandry suffers from a confusion of tongues. To clarify positions of various stakeholder
groups in their joint search for acceptable solutions, the concept of animal welfare was split up into three notions: no suffering,
respect for intrinsic value, and non-appalling appearance of animals. This strategy was based on the hypothesis that multi-stakeholder
solutions should be based on shared values rather than on compromises. The usefulness of such an artificial value distinction
strategy was tested in a small series of experiments. The results demonstrate that the chosen concept to distinguish between
values is effective in a stakeholder context. Farmers’ views on doing good to animals appeared to be largely based on their
value to prevent suffering and predominantly focused on the provision of regular care. Their priority for this value is clearly
shared with other stakeholders, providing a basis for joint solutions. The concept of intrinsic value does not play a discernable
role in farmers’ considerations. Based on the varying views on welfare, it can be inferred that there is a gradual rather
than a principal difference between government legislation and farmers’ values, whereas public perception and acceptance of
farm practices remains complicated. Distinction between value groups and focusing on a selected notion (such as no suffering)
proved to be effective in bringing representatives of stakeholder groups together, but is unlikely to bridge the emotional
gap between commercial farm practices and public ideals. 相似文献

Wildfire, like many natural hazards, affects large landscapes with many landowners and the risk individual owners face depends
on both individual and collective protective actions. In this study, we develop a spatially explicit game theoretic model
to examine the strategic interaction between landowners’ hazard mitigation decisions on a landscape with public and private
ownership. We find that in areas where ownership is mixed, the private landowner performs too little fuel treatment as they
“free ride”—capture benefits without incurring the costs—on public protection, while areas with public land only are under-protected.
Our central result is that this pattern of fuel treatment comes at a cost to society because public resources focus in areas
with mixed ownership, where local residents capture the benefits, and are not available for publicly managed land areas that
create benefits for society at large. We also find that policies that encourage public expenditures in areas with mixed ownership,
such as the Healthy Forest Restoration Act of 2003 and public liability for private values, subsidize the residents who choose
to locate in the high-risk areas at the cost of lost natural resource benefits for others. 相似文献

In the beginning, policy debates between critics and advocates of genetically modified (GM) crops focused on scientifically
determined risks. Ten years later, the argument between environmentalists or consumers and regulators or industry has changed
into a discussion about the implementation of more democratic policymaking about GM farming. A notable omission from the political
debate about food biotechnology in the United States, however, is the opinion of farmers who cultivate the GM crops. Policymakers
should value practical knowledge based on experiences from farmers, not only scientific industry reports or consumer product
opinions. This project uses in-depth interviews to create an original mail survey that uses the practical discourse of farmers
in order to explore the relationship of farmer attitudes and GM agriculture. Although national research indicates that larger
yields are the most common reason for GM adoption, qualitative information suggest that the potential of GM crops to increase
revenue per acre does not truly reflect all the concerns of modern farmers. For example, farmers who use GM seeds indicate
that they constantly question the social impacts of their agricultural practices. As such, GM policies should be restructured
as a political rationalization of both economic modeling and political theory because this research suggests that farmers’
business decisions are utility calucations that consider economics without ignoring environmental and political contexts.
Farmers’ concerns about non-economic risks suggest that they need more information about GM crops and that governmental policies
should respond to their interests, as they are more democratic or pluralistic than industry or consumer arguments. 相似文献

Comanagement has recently become the most popular approach for reconciling land claims and biodiversity conservation in South
Africa and beyond. Following the resolution of land claims on protected areas in South Africa, comanagement arrangements have
been created between the relevant conservation authorities and the land claimant communities who are legally awarded tenure
rights to the land. However, it is doubtful that these partnerships constitute success for the former land claimants. Using
the case of a “resolved” land claim in Mkambati Nature Reserve, Eastern Cape Province, as well as insights from comanagement
literature, this paper identifies and discusses three key possible reasons for the unimpressive performance of comanagement
in reconciling land restitution and conservation. The first one is the origins of the comanagement idea in the conservation
of high value natural resources (e.g., fisheries, forestry), rather than in or including concerns for resource rights. The
second reason is the neglect of key conditions for successful comanagement, as discussed in the comanagement literature. The
final reason is the ambiguity in settlement agreements, including the use of terminology and concepts that reinforce unequal
power relationships, with the state emerging as the powerful partner. This paper concludes that, unless there is a serious
reassessment of the comanagement idea as a way of reconciling land reform and conservation, and a possible review of settlement
agreements that have relied on comanagement, both the integrity of the “successful land claimant’s rights” and that of conservation
remain under threat. 相似文献

The East Usambara Mountains, recognized as one of the 25 most important biodiversity hot spots in the world, have a high degree
of species diversity and endemism that is threatened by increasing human pressure on resources. Traditional slash and burn
cultivation in the area is no longer sustainable. However, it is possible to maintain land productivity, decrease land degradation,
and improve rural people’s livelihood by ameliorating cultivation methods. Improved agroforestry seems to be a very convincing
and suitable method for buffer zones of conservation areas. Farmers could receive a reasonable net income from their farm
with little investment in terms of time, capital, and labor. By increasing the diversity and production of already existing
cultivations, the pressure on natural forests can be diminished. The present study shows a significant gap between traditional
cultivation methods and improved agroforestry systems in socio-economic terms. Improved agroforestry systems provide approximately
double income per capita in comparison to traditional methods. More intensified cash crop cultivation in the highlands of
the East Usambara also results in double income compared to that in the lowlands. However, people are sensitive to risks of
changing farming practices. Encouraging farmers to apply better land management and practice sustainable cultivation of cash
crops in combination with multipurpose trees would be relevant in improving their economic situation in the relatively short
term. The markets of most cash crops are already available. Improved agroforestry methods could ameliorate the living conditions
of the local population and protect the natural reserves from human disturbance. 相似文献

Soil, water and nutrient conservation in mountain farming systems: case-study from the Sikkim Himalaya 总被引:3,自引:0,他引:3
The Khanikhola watershed in Sikkim is agrarian with about 50% area under rain-fed agriculture representing the conditions of the middle mountains all over the Himalaya. The study was conducted to assess overland flow, soil loss and subsequent nutrient losses from different land uses in the watershed, and identify biotechnological inputs for management of mountain farming systems. Overland flow, soil and nutrient losses were very high from open agricultural (cropped) fields compared to other land uses, and more than 72% of nutrient losses were attributable to agriculture land use. Forests and large cardamom agroforestry conserved more soil compared to other land uses. Interventions, like cultivation of broom grass upon terrace risers, N2-fixing Albizia trees for maintenance of soil fertility and plantation of horticulture trees, have reduced the soil loss (by 22%). Soil and water conservation values (> 80%) of both large cardamom and broom grass were higher compared to other crops. Use of N2-fixing Albizia tree in large cardamom agroforestry and croplands contributed to soil fertility, and increased productivity and yield. Bio-composting of farm resources ensured increase in nutrient availability specially phosphorus in cropped areas. Agricultural practices in mountain areas should be strengthened with more agroforestry components, and cash crops like large cardamom and broom grass in agroforestry provide high economic return and are hydroecologically sustainable. 相似文献

China’s new Classification-Based Forest Management (CFM) is a two-class system, including Commodity Forest (CoF) and Ecological
Welfare Forest (EWF) lands, so named according to differences in their distinct functions and services. The purposes of CFM
are to improve forestry economic systems, strengthen resource management in a market economy, ease the conflicts between wood
demands and public welfare, and meet the diversified needs for forest services in China. The formative process of China’s
CFM has involved a series of trials and revisions. China’s central government accelerated the reform of CFM in the year 2000
and completed the final version in 2003. CFM was implemented at the provincial level with the aid of subsidies from the central
government. About a quarter of the forestland in China was approved as National EWF lands by the State Forestry Administration
in 2006 and 2007. Logging is prohibited on National EWF lands, and their landowners or managers receive subsidies of about
70 RMB (US$10) per hectare from the central government. CFM represents a new forestry strategy in China and its implementation
inevitably faces challenges in promoting the understanding of forest ecological services, generalizing nationwide criteria
for identifying EWF and CoF lands, setting up forest-specific compensation mechanisms for ecological benefits, enhancing the
knowledge of administrators and the general public about CFM, and sustaining EWF lands under China’s current forestland tenure
system. CFM does, however, offer a viable pathway toward sustainable forest management in China. 相似文献

Land-Use and Land-Cover Change in Montane Mainland Southeast Asia 总被引:12,自引:1,他引:12
This paper summarizes land-cover and land-use change at eight sites in Thailand, Yunnan (China), Vietnam, Cambodia, and Laos
over the last 50 years. Project methodology included incorporating information collected from a combination of semiformal,
key informant, and formal household interviews with the development of spatial databases based on aerial photographs, satellite
images, topographic maps, and GPS data. Results suggest that land use (e.g. swidden cultivation) and land cover (e.g. secondary
vegetation) have remained stable and the minor amount of land-use change that has occurred has been a change from swidden
to monocultural cash crops. Results suggest that two forces will increasingly determine land-use systems in this region. First,
national land tenure policies—the nationalization of forest lands and efforts to increase control over upland resources by
central governments—will provide a push factor making it increasingly difficult for farmers to maintain their traditional
swidden land-use practices. Second, market pressures—the commercialization of subsistence resources and the substitution of
commercial crops for subsistence crops—will provide a pull factor encouraging farmers to engage in new and different forms
of commercial agriculture. These results appear to be robust as they come from eight studies conducted over the last decade.
But important questions remain in terms of what research protocols are needed, if any, when linking social science data with
remotely sensed data for understanding human-environment interactions. 相似文献

The study presented in this article used a combination of key informant interviews and a review and synthesis of existing country level literature to identify the major sources of land tenure insecurity in six Southern African countries: Botswana, Lesotho, Malawi, Mozambique, South Africa, and Zambia. Findings reveal that the main causes of land tenure insecurity experienced in Southern Africa include lack of land rights of minority groups, unclear or overlapping land rights, overcrowding, land alienation into leasehold, insecurity of farm workers and farm labour tenants, inappropriate and exploitative administrative practices, land encroachment and illegal settlers and limited women's land rights. The article presents a summary of land tenure security related initiatives that the study countries have or are in the process of adopting. Analysis of these initiatives shows that tenure reforms have focused on changing the law and rules but little has been done to translate new laws into implementable programs; capacity building; prioritization of resources to support tenure reform; provision of complementary policies and incentives; addressing HIV/AIDS‐land tenure related problems; and monitoring and evaluation. The paper contends that these policy issues should be addressed in order to ensure realization of land tenure security for all. 相似文献

Agroforestry is often an economically viable land-use option for the environmental rehabilitation of salinized cropping areas in irrigated drylands, but afforestation initiative at the farm level is subject to various socio-political constraints. We analyzed the factors that affect farmer decisions with respect to the agroforestry adoption using an ex ante approach through Ethnographic Decision Tree Modeling (EDTM). Constraints on agroforestry adoption were identified via a review of legal documents, focus-group discussions, and a farm survey in northwest Uzbekistan. The findings highlighted the importance of farmer perceptions of risk with respect to decision making surrounding the adoption of alternative land uses. The EDTM analysis allowed determining those policy incentives for afforestation that could directly influence the decision-making process of potential participants. In particular, there is a need for increased land-use flexibility, improved land tenure and tree plantation proprietorship security, increased awareness raising and training in agroforestry practices, and greater institutional support. 相似文献

According to the Seventh National Forest Inventory (2004–2008), China’s forests cover an area of 195.45 million ha, or 20.36%
of the total land area. China has the most rapidly increasing forest resources in the world. However, China is also a country
with serious forest pest problems. There are more than 8,000 species of potential forest pests in China, including insects,
plant diseases, rodents and lagomorphs, and hazardous plants. Among them, 300 species are considered as economically or ecologically
important, and half of these are serious pests, including 86 species of insects. Forest management and utilization have a
considerable influence on the stability and sustainability of forest ecosystems. At the national level, forestry policies
always play a major role in forest resource management and forest health protection. In this paper, we present a comprehensive
overview of both achievements and challenges in forest management and insect pest control in China. First, we summarize the
current status of forest resources and their pests in China. Second, we address the theories, policies, practices and major
national actions on forestry and forest insect pest management, including the Engineering Pest Management of China, the National
Key Forestry Programs, the Classified Forest Management system, and the Collective Forest Tenure Reform. We analyze and discuss
three representative plantations—Eucalyptus, poplar and Masson pine plantations—with respect to their insect diversity, pest problems and pest management measures. 相似文献

South Korea’s Civilian Control Zone (CCZ), a relatively untouched area due to tight military oversight since the end of Korean
War, has received considerable attention nationally and internationally for its rich biodiversity. However, the exclusion
of local communities from the process of defining problems and goals and of setting priorities for biodiversity conservation
has halted a series of biodiversity conservation efforts. Through qualitative research, we explored CCZ farmers’ views of
key problems and issues and also the sources of their opposition to the government-initiated conservation approaches. Key
findings include the farmers’ concerns about the impact of conservation restrictions on their access to necessary resources
needed to farm, wildlife impacts on the value of rice and other agricultural goods they produce, and farmers’ strong distrust
of government, the military, and planners, based on their experiences with past conservation processes. The findings regarding
farmers’ perceptions should prove useful for the design of future participatory planning processes for biodiversity conservation
in the CCZ. This case highlights how conservative measures, perceived to be imposed from above—however scientifically valuable—can
be undermined and suggests the value that must be placed on communication among planners and stakeholders. 相似文献

Sanjiang National Nature Reserve (NNR) is a state-owned natural wetland in China that has suffered severe degradation due
to cultivation and wetland reclamation by farmers. As a consequence, the conversion of cultivated land to wetlands (CCW) was
proposed by the government of Heilongjiang province and the United Nations Development Programme/Global Environment Facility
(UNDP/GEF) project team in 2007. We suggest that voluntary participation in the CCW could be an important tool for accomplishing
the integrated objectives of wetland conservation and local development. The purpose of this study was to examine the main
factors that influence farmers’ willingness to participate in the CCW through a field investigation and a questionnaire. Based
on the data from our questionnaire, which provided an effective sample of 310 households in 11 villages, the influencing factors
of farmers’ willingness to participate were analyzed through binary logistic regression analyses. It was concluded that age,
education, the amount of cultivated land, geographical location, and the perceived benefits and risks were important factors
for participation. Furthermore, suggestions for improving the wetland compensation system and providing alternative livelihoods
are proposed to strengthen participation. 相似文献

Although contract sugarcane farming is the most dominant and popular land use among farmers in Nzoia Sugarbelt, results from
a 2007 study suggests that the intended goal of increasing farmers’ incomes seems to have failed. With a mean monthly income
of Kenya Shillings 723 (US $ 10) from an average cane acreage of 0.38 hectares, it would be difficult for a household of eight
family members to meet their basic needs and lead a decent life. Analysis of farmer statements showed that up to 86% of the
changes in net income were significantly determined by six cost variables as a group (i.e., acreage, tillage costs, seedcane
costs, transport costs, yield, and farmer’s education level). Area under sugarcane had the greatest influence on net income
whereby an increase in one hectare under cane would result in an increase of Kenya Shillings 110,427 in net income (per crop
cycle of 21 months), holding other variables constant. This translates into Kenya shillings 5,258 per month (or 175 per day
per household, or for a family of eight people—KES 22 or US $ 10) from an average cane acreage of 0.38 hectares, it would be difficult for a household of eight
family members to meet their basic needs and lead a decent life. Analysis of farmer statements showed that up to 86% of the
changes in net income were significantly determined by six cost variables as a group (i.e., acreage, tillage costs, seedcane

whereby an increase in one hectare under cane would result in an increase of Kenya Shillings 110,427 in net income (per crop

per household, or for a family of eight people—KES 22 or US 0.3) per member, which is far below the international standard
of absolute poverty. Key net income depressors were tillage, seedcane, and transportation costs, all of which were determined
by the company with no input from farmers. To bridge income gaps between the company and farmers in favor of sustainable community
livelihoods, this paper argues strongly for the need to institutionalize Corporate Social Responsibility within the daily
operations of the company particularly to address net-income depressors. Ten key building blocks for such a policy for Nzoia
Sugar Company are suggested, based on farmers’ responses and ethical considerations. 相似文献

Excessive exploitation of and skewed access to dwindling water resources raise serious water justice concerns. Environmental justice movements and related literature have raised critical questions regarding the unequal distribution of the costs and benefits of a development paradigm that is founded on excessive exploitation and appropriation of natural resources. This paper explores the growing relevance of a water justice framework that addresses both the social and ecological aspects of water use and appropriation, with reference to a four-decade long water conflict over the Chaliyar River in Kerala, South India. It highlights how ecosystem degradation and denial of justice go hand in hand. The paper argues that the framing and articulation of the conflict in a partisan manner led to the glossing over of certain critical features, thus preventing a full view of water injustices. It also failed to inform subsequent policies and practices in this regard. 相似文献

This article assesses the role of local institutions in managing irrigation water use. Fifty irrigation systems in each country
were studied in Nepal and Thailand to compare the influence of local institutions on performance of irrigation systems amid
changes in external policy and market pressures. Nepal’s new irrigation policy after the re-instatement of multiparty democracy
in 1990 emphasized participatory irrigation management transferring the management responsibility from state authorities to
water users. The water user associations of traditional farmer-managed irrigation systems were formally recognized by requiring
registration with related state authorities. In Thailand also government policies encouraged people’s participation in irrigation
management. Today water users are directly involved in management of even some large irrigation systems at the level of tertiary
canals. Traditional communal irrigation systems in northern Thailand received support for system infrastructure improvement
but have faced increased interference from government. In Thailand market development supported diversification in farming
practices resulting in increased areas under high water-demanding commercial crops in the dry season. In contrast, the command
areas of most irrigation systems in Nepal include cereal-based subsistence farming with only one-third having commercial farming.
Cropping intensities are higher in Nepal than in Thailand reflecting, in part, differences in availability of land and management.
In both countries local institutions play an important role in maintaining the performance of irrigation systems as external
drivers and local contexts change. Local institutions have provided alternative options for irrigation water use by mediating
external pressures. 相似文献
