This paper examines the effects of growing land pressure on the distribution and quality of cropland allocations on customary tenured land (CTL) in Swaziland. Within the wider Sub‐Saharan context, the reform of indigenous tenure systems is now generally seen as a process of adaptation rather than replacement. The legal recognition of (existing and future) user rights is considered a practical way forward. This essentially rights‐based approach may divert attention from technical inadequacies indigenous systems may have, particularly under conditions of increasing land pressure. The case of CTL substantiates such shortcomings. CTL has seen a marked growth in population and land allocations since Independence. This had led to concerns on the land distribution efficiency in view of the improved agricultural production required to sustain the increasing number of rural households. By analysing historical changes in the number, size and quality of cropland allocations in selected rural communities, this paper demonstrates the occurrence of a high degree of inconsistency in cropland distribution at the community level, as well as inefficient land distribution at higher levels of scale. These shortcomings threaten the sustainability of the local agricultural production systems, and will need to be addressed in any meaningful reform process. 相似文献

Improved techniques for measuring and monitoring the state of biodiversity are required for reporting on national obligations
to international and regional conservation institutions. Measuring the extent of grazing-related degradation in semi-arid
ecosystems has proved difficult. Here we present an accurate and cost-effective method for doing this, and apply it in a South
African semi-arid region that forms part of a globally significant biodiversity hotspot. We grouped structurally and functionally
similar vegetation units, which were expert-mapped at the 1:50,000 scale, into four habitat types, and developed habitat-specific
degradation models. We quantified degradation into three categories, using differences between dry and wet season values of
the Normalized Difference Vegetation Index (NDVI) for the three succulent karoo habitats, and the difference between maximum
and mean NDVI values for the subtropical thicket habitat. Field evaluation revealed an accuracy of 86%. Overall, degradation
was high: 24% of the study area was modeled as severely degraded, and only 9% as intact. Levels of degradation were highest
for bottomland habitats that were most exposed to grazing impacts. In sharp contrast to our methods, a widely used, broad-scale
and snapshot assessment of land cover in South Africa was only 33% accurate, and it considerably underestimated the extent
of severely degraded habitat in the study area. While our approach requires a multidisciplinary team, and in particular expert
knowledge on the characteristics and spatial delimitation of vegetation types, it is repeatable, rapid, and relatively inexpensive.
Consequently, it holds great promise for monitoring and evaluation programs in semi-arid ecosystems, in Africa, and beyond. 相似文献

Implementing Participatory Decision Making in Forest Planning 总被引:2,自引:0,他引:2
Ananda J 《Environmental management》2007,39(4):534-544
Forest policy decisions are often a source of debate, conflict, and tension in many countries. The debate over forest land-use
decisions often hinges on disagreements about societal values related to forest resource use. Disagreements on social value
positions are fought out repeatedly at local, regional, national, and international levels at an enormous social cost. Forest
policy problems have some inherent characteristics that make them more difficult to deal with. On the one hand, forest policy
decisions involve uncertainty, long time scales, and complex natural systems and processes. On the other hand, such decisions
encompass social, political, and cultural systems that are evolving in response to forces such as globalization. Until recently,
forest policy was heavily influenced by the scientific community and various economic models of optimal resource use. However,
growing environmental awareness and acceptance of participatory democracy models in policy formulation have forced the public
authorities to introduce new participatory mechanisms to manage forest resources. Most often, the efforts to include the public
in policy formulation can be described using the lower rungs of Arnstein’s public participation typology. This paper presents
an approach that incorporates stakeholder preferences into forest land-use policy using the Analytic Hierarchy Process (AHP).
An illustrative case of regional forest-policy formulation in Australia is used to demonstrate the approach. It is contended
that applying the AHP in the policy process could considerably enhance the transparency of participatory process and public
acceptance of policy decisions. 相似文献

Urban planning involves compromise between the diverse and often contradictory issues supported by the different stakeholders. The literature generally agrees on the need to broaden the participation base to overcome this difficulty. However, participation should not be limited to problem solving, but should also take place in the problem setting phase. This paper proposes a participatory diagnosis process for structuring the problem setting phase. We describe an experiment in a participatory diagnosis conducted with the residents of a Geneva neighborhood. The experiment began by identifying the residents' concerns, which were then reformulated under broader issues. Some 20 spatial indicators were built using GIS tools, and were then applied in a second phase of resident consultations to assess the relative importance of each issue. The ensuing priority issues formed the core of the diagnosis. The approach emphasized comparison between the daily experiences of residents and so-called official information (i.e. census tract, traffic measurement, and so on). The residents were therefore involved in a learning process that allowed them to consolidate or modify their opinions. The process led to the emergence of a clearly defined collective awareness that supplanted individual aspirations. 相似文献

Stakeholder participation has become a key factor in the success of grassroots conservation and natural resource management
programs. Yet the majority of program evaluations are conducted by external consultants for the purposes of accountability,
rather than program improvement. Too often, systematic evaluations of conservation programs are not conducted at all. The
objective of this study was to build the capacity of a grassroots conservation organization to conduct participatory evaluation, involving project stakeholders in the design, implementation, and use of evaluation. The study applied a conceptual
model for participatory evaluation to the Wildlife Clubs of Kenya (WCK), the largest grassroots conservation program for youth
in Africa, involving more than one million youth since 1968.
Seven trainings in participatory evaluation were conducted with WCK staff, teachers, and community members. The 120 participants,
representing nine WCK regions with 800 clubs, showed a significant increase in attitudes and knowledge regarding evaluation,
as reflected by mean test scores before and after training. To institutionalize evaluation at WCK, existing organizational
practices were assessed and used as a foundation for developing an evaluation system.
Based on club competitions, a new evaluation initiative was launched called the WCK Incentive Program. Participants in all
seven workshops identified indicators and sources of evidence for this evaluation system, which now serves as a basis for
rewarding outstanding performance in WCK. This study revealed the importance of incentives for evaluation, the need to build
on existing structures to promote organizational learning, and the necessity for the conservation community to commit resources
to capacity building in participatory evaluation. 相似文献

Contributing to the debate on the causes of Himalayan environmental degradation, the status and management of four watersheds
in the Upper Pokhara Valley were studied using information available from land use analysis, household surveys conducted in
1989 and 1992, deliberations held with villagers, and field observations. Accordingly, areas under forests and grazing lands
were found being depleted at relatively high rates between 1957 and 1978 due mainly to the government policy of increasing
national revenue by expansion of agricultural lands, nationalization of forests, steadily growing population, and dwindling
household economy. Despite the steady growth of population, this process had remarkably slackened since 1978, owing primarily
to remaining forests being located in very, steep slopes and implementation of the community forestry program. Forests with
relatively sparase tree density, however, and grazing lands in the vicinity of settlements have been undergoing degradation
due to fuelwood and fodder collection and livestock grazing. In many instances, this is aggravated by weak resource management
institutions. Being particularly aware of the economic implication of land degradation, farmers have adopted assorted land
management practices. Still a substantial proportion ofbari lands in the hill slopes is vulnerable to accelerating degradation, as the arable cropping system is being practiced there
as well. The perpetuation of the local subsistence economy is certain to lead, to a further deterioration of the socioeconomic
and environmental conditions of watersheds. To facilitate environmental conservation and ecorestructuring for sustainable
development, a broad watershed management strategy is outlined with focus on alleviating pressure on natural resources. 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

This article examines the utilization characteristics and importance of woody biomass resources in the rural-urban fringe
zones of Botswana. In the literature for Africa, attention has been given to the availability and utilization of biomass in
either urban or rural environments, but the rural-urban fringe has been neglected. Within southern Africa, this neglect is
not justified; the rural-urban fringe, not getting the full benefits available in urban environments in Botswana, has developed
problems in woody biomass availability and utilization that require close attention. In this article, socioeconomic data on
the importance of woody biomass in the Batlokwa Tribal Territory, on the rural-urban fringe of Gaborone, Botswana, were collected
together with ecologic data that reveal the utilization characteristics and potential for regrowth of woody biomass. The analysis
of these results show that local woody biomass is very important in the daily lives of communities in the rural-urban fringe
zones and that there is a high level of harvesting. However, there is no effort in planning land use in the tribal territory
to either conserve this resource or provide alternatives to its utilization. The future of woody biomass resources in Botswana’s
rural-urban fringe is uncertain. The investigators recommend that a comprehensive policy for the development of the rural-urban
fringe consider the importance of this resource. The neglect of this resource will have far-reaching implications on the livelihoods
of residents as well as the environment in this zone. 相似文献

Troubles on the way: An analysis of the challenges faced by multi-stakeholder platforms 总被引:2,自引:0,他引:2
Nicolas Faysse 《Natural resources forum》2006,30(3):219-229
Multi‐stakeholder platforms (MSPs) have been widely promoted as a promising means of resolving conflicts over natural resources, first in developed countries and, more recently, as a global good practice. However, many MSPs have been implemented in an unfavourable context — primarily of social inequities — and have not met initial high expectations. The article analyzes the challenges MSPs face in an unfavourable context, and identifies five main issues:
- ? Power relationships;
- ? Platform composition;
- ? Stakeholder representation and capacity to participate meaningfully in the debates;
- ? Decision‐making power and mechanisms; and finally
- ? Cost of setting up an MSP.

The paper defines the concept of land degradation and costs and effects of soil erosion. Through the concept of optimal levels of soil erosion, a conceptual model of the social costs of soil degradation is elaborated. The discussion focuses on the measurement aspects of the economic scarcity of soil in the agriculture sector. Reliable estimates of the true impacts of soil degradation can only be made if data on marginal damage costs and marginal conservation costs are available. The different scarcity indicators are evaluated and competitive land rental prices are considered as appropriate in indicating soil scarcity in agriculture. 相似文献

In this contemporary interpretation of the widespread land degradation problem in Southeast Asia, it is hypothesized that spatial interplay of environmental and socioeconomic predictors determines the occurrence of land degradation. Village surveys, remote sensing and spatial auto‐logistic modelling of the relationship between degradation and land use dynamics in Lam Phra Phloeng watershed of Thailand enabled 80.2% of land to be classified correctly in terms of the presence or absence of erosion and explained 53.2% of the total variation. Cultivation and dependence on agriculture for livelihood positively and significantly affect degradation. Lack of access to institutional credit and land titles significantly increased the probability of occurrence of degradation. On the other hand, education and social cohesion are negatively associated with the occurrence of degradation. The Relative Operating Characteristic (ROC) curve was used to measures the performance of the model. The calculated area under the curve (0.879) suggests that significant predictor variables in the model can be confidently used to forecast the likelihood of occurrence of degradation and thus to identify priority areas for intervention. Policies to reduce land degradation should include measures to reduce pressure on the land, including alternative income sources. Policies could mobilize capital to invest in encouraging nature‐based tourism and other off‐farm income options. 相似文献

Forestry-based carbon sequestration projects in Africa: Potential benefits and challenges 总被引:3,自引:0,他引:3
Carbon sequestration through forestry and agroforestry can help mitigate global warming. For Africa, carbon sequestration also represents an opportunity to fund sustainable development through financial inflows. However, with a low share of global carbon trade, there are strong concerns that African countries are losing out on this valuable opportunity. Through a comprehensive review of 23 carbon sequestration projects across 14 countries, this paper discusses ways to overcome critical challenges to scale up carbon investments in Africa. These projects are expected to sequester 26.85 million tCO2 beyond the baseline situation. Within the continent, East Africa is the preferred destination for carbon investors. Most projects are non‐Kyoto compliant and represent voluntary emission reductions. While project benefits such as increased local incomes and improved natural resources are promising, there are concerns that conversion of grasslands into tree plantations can harm local ecosystems. Insecure land tenure constrains new investments and increases the risk that local communities will lose access to forests. Another challenge is that projects with smallholders have high transaction costs. These costs can be overcome by building strong community institutions and simplifying project guidelines. To attract more projects, African governments will need to build their capacity to identify relevant opportunities. 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

The term "barren hills" has been a keyword for land degradation in the uplands of Vietnam for over a decade. Nevertheless, the "barren" land is still not adequately ecologically characterized. In this work, we analyze land use-induced changes in vegetation and soil properties along a sequence of barren hills types formed on one physiotope. The study is undertaken in the Bac Kan province, one of the poorest upland regions where livestock plays an important role. A transition from an old-growth laurel forest to a sparse manmade grassland is characterized by a total of 177 species, rapid species turnover, and discrete dominants, and an overwhelming effect of disturbance history on both soil and vegetation patterning. Land degradation is most apparent in land use-induced maintenance of arrested successions, and the regeneration course is shifted towards drier formations. We hypothesize a conceptual model as an aid to understanding the process of early fallow differentiation in response to the patterned, fine-scale disturbances. The larger-scale implications of the observed trends in regeneration potentials deviation, and, in particular, the effect of water buffaloes in halting fallow successions, are discussed. 相似文献

The relationship between migration and deforestation in the developing world continues to receive significant attention. However beyond direct population increase, the precise mechanisms that operate within the intersection of migrant/host land rights remain largely unexamined. Where migrants are provided with land and rights by the State and/or local communities, how such rights are perceived by the migrants is of primary importance in their interaction with land resources, and in aggregate it impacts the development opportunities and environmental repercussions of migration. The authors analyze the operative aspects of land rights reception (as opposed to provision) by migrant populations, and the relationship between this reception and deforestation. The article examines a case in Zambia to analyze how tenurial constructs, emerging from the way rights are perceived by migrants, lead to the continued clearing of areas much larger than needed for cultivation, even when the arrangement appears counter‐productive in terms of land rights provision and labour allocation. While valuable policy efforts have focused on providing resource rights to migrants, how such rights are received and the relationship of this reception to resource management needs greater policy attention. 相似文献

Land degradation continues to be a major threat to local and national food security. With limited potential to develop new land, any increase in agricultural production must be sought largely through the better use of land already under cultivation. Concerns for the global environment associated with agriculture worldwide have also increased in recent years and require more coordinated efforts at global and national levels with decentralisation of activities at the local level.
This article presents an overview of land resources potential for food production, the processes and extent of land degradation and its economic and environmental costs and impacts, and highlights some macro-economic policies and institutional measures for the prevention of land degradation and rehabilitation of degraded lands. A people-centred programme is presented as a basis for decentralising activities for sustainable land use and land management. Finally, the need for better coordinated efforts of concerned UN, multinational agencies and NGOs for the implementation of Agenda 21 and related conventions is stressed. 相似文献

REDD+, a climate change mitigation mechanism that values carbon in tropical forests, is expected to provide Africa with a range of environmental and socio‐economic benefits. Drawing on a vast array of literature and personal experiences, this review analyzed particular features and challenges that REDD+ implementation has faced on the continent. The distinct contexts and major challenges regarding governance, finance and technical capacities are discussed, and mechanisms to fill these gaps are suggested. Radical land tenure reform and a perfect safeguard mechanism that transfers forest land and carbon to the communities are unlikely. REDD+ should rather look for systems that respect local institutional arrangements, and allow forest‐based communities to participate in decision‐making and benefit sharing, particularly benefits from emerging REDD+. Finances for REDD+ infrastructure and the results‐based payment are in short supply. While negotiating for potential external sources in the short term, Africa should generate domestic financial resources and look for additional payments for ecosystem services. Africa should also negotiate for forest monitoring capacity building, while strengthening local community forest monitoring. This review contributes to an improved understanding of the contexts and challenges to consider in the capacity and policy development for REDD+ implementation. 相似文献

Innovative approaches to rural development: Moving from state-controlled towards market-based land reform 总被引:1,自引:0,他引:1
Frederico Neto 《Natural resources forum》2004,28(1):50-60
Among the world's poor, approximately 75% of those in extreme poverty live and work in rural areas and two‐thirds of them depend mainly on farming or farm labour for their livelihood. Policies to grant the rural poor secure access to land and water for irrigation — and to improve the economic efficiency of small‐scale agriculture — can thus play a critical role in the implementation of rural development strategies, including efforts to combat rural poverty. Since inadequate access to arable land is probably the most important cause of rural poverty, redistributive land reform is increasingly seen as crucial for socio‐economic development and poverty alleviation in many developing countries with substantial amounts of (unused) arable state land or (under‐utilized) large private landholdings. This article argues that market‐based land redistribution schemes, such as the one being implemented in South Africa, can be considered one of the most innovative approaches to land reform that have emerged over the last decade. These schemes thus provide a useful alternative to more conventional, state‐controlled land redistribution programmes. The article concludes, however, that when countries opt for market‐based approaches to land redistribution, the State still has an important role to play, without necessarily deciding which land parcels change hands. 相似文献

Land Degradation: A Challenge to Ethiopia 总被引:11,自引:3,他引:8
Taddese G 《Environmental management》2001,27(6):815-824
Land degradation is a great threat for the future and it requires great effort and resources to ameliorate. The major causes
of land degradation in Ethiopia are the rapid population increase, severe soil loss, deforestation, low vegetative cover and
unbalanced crop and livestock production. Inappropriate land-use systems and land-tenure policies enhance desertification
and loss of agrobiodiversity. Utilization of dung and crop residues for fuel and other uses disturbs the sustainability of
land resources. The supply of inputs such as fertilizer, farm machinery and credits are very low. The balance between crop,
livestock, and forest production is disturbed, and the farmer is forced to put more land into crop production. For environmentally
and socially sustainable development, there is an urgent need to promote awareness and understanding of the interdependence
of natural, socioeconomic, and political systems at local and national levels. Understanding the current status and causes
of land degradation is very important. This paper reveals the important elements of land degradation in Ethiopia and suggests
possible solutions that may help to ameliorate the situation. 相似文献

k -means nonhierarchical cluster analysis using farm size, slope, and distance to the nearest city center and highway as surrogates
of farmland conversion. Discriminant analysis showed that the two groups derived from the cluster analysis were 98.8% accurate
(P < 0.0000). Results from the statistical analysis may serve as a starting point for the identification of individual farms
prone to residential development. To explain the driving forces of farmland conversion to residential uses, interviews should
be conducted with farmers, landowners, and land buyers. The use of multivariate statistical techniques to identify farms in
jeopardy of residential development, in conjunction with qualitative assessments that explain the probability of development
of individual farms, may prove a useful strategy to understand and predict farmland conversion. 相似文献
