Toward integrated water and agricultural land management: Participatory design of agricultural landscapes

One of the great challenges of developing sustainable water management is to integrate water and land use issues, and to favor stakeholders’ involvement in the process of designing a solution to the specific issues of water basins. This study aims to help reach these objectives: we present the outcomes of a methodology that aims to design, with stakeholders of a watershed facing quantitative water management issues, alternative agricultural landscapes that they each consider as potential solutions. Our design approach combines (1) facilitation of participatory workshops for designing changes in cropping systems and their spatial distributions at the landscape level with (2) formalization of these alternatives in a GIS. The formalized alternatives provide precise information about fields, farms and areas concerned by the designed changes. We present two sample results of this methodology implemented in a 840 km² irrigated landscape located in a water-deficient watershed in southwestern France. We discuss how our design approach may be useful for a wider design-and-assessment methodology involving researchers and stakeholders with conflicting interests. We show that our co-design approach provides fertile ground for the emergence of salient, credible and legitimate change options.     

Paying for ecological services in Ecuador: The political economy of structural inequality

Paying Indigenous communities to conserve land for carbon sequestration is a controversial way of tackling climate change. Critics argue that paying for ecological services (or ‘PES’) in the form of carbon offset programmes reduces land and social relations to an economic transaction that devalues Indigenous livelihoods and communities. At the same time, empirical studies have shown that Indigenous communities have accepted and even embraced the idea of being paid to conserve land for climate change mitigation. This paper explores this apparent contradiction by investigating the implementation of Programa Socio Bosque (PSB), a PES carbon sequestration programme in Ecuador. Drawing upon primary fieldwork in the highland province of Chimborazo, it makes the case that PES programmes need to be understood as form of state power that reconfigures and reinforces the ways in which Indigenous peoples engage with the state. Particularly important in this regard is the role of the state in reinforcing the agrarian conditions under which Indigenous communities use and interpret PES payments while at the same time reconfiguring new forms of land conservation. Empirically, the research reveals important complementarities between the goals of carbon sequestration PES programmes and Indigenous land-use practices. Methodologically, it highlights the importance of situating the study of PES programmes in a context of land struggles, community–state relations and agrarian change.     

Auction winning,social dynamics and non-compliance in a payment for ecosystem services scheme in Indonesia

Conservation auctions for payment for ecosystem services (PES) are useful to identify the levels of incentives that will cover the opportunity costs of farmers supplying ecosystem services. Although auctions are increasingly used for allocation in PES schemes, the factors that lead to their successful implementation and eventual environmental outcomes are poorly understood in developing countries. We investigated the socio-economic and institutional contexts that led to smallholders' auction winning and eventual compliance using linear mixed-effects models, and post-auction and post-contract surveys. We employed a case study of a conservation contract preceded by a sealed-bid, multiple round, uniform price auction for watershed services from coffee farmers in Lampung, Indonesia. The auction participants presented low education levels, low asset endowments and small plot sizes. The study obtained evidence that farmers with larger plot areas were more likely to win the contracts, suggesting economies of scale. Most farmers considered the auction a fair self-selection mechanism to allocate contracts where allocation was not influenced by power or social rank. Non-compliance was associated with labor availability constraints, short duration of land ownership and existence of previous conservation applications, suggesting lax of capability to invest in applying conservation agriculture. Final bids were however not good predictors of compliance, among other factors, calling into question the potential of auctions to elicit the actual incentive from the farmers. Ensuring that farmers understand the purposes of auctions for effective contract allocation beyond a mere game and identifying farmers that might encounter difficulties fulfilling the contract could increase the likelihood that such a PES scheme would be successful.     

Payments for environmental services in Indonesia: What if economic signals were lost in translation?

This article provides an analysis of a payment for environmental services (PES) scheme in the Cidanau watershed, Indonesia. It contributes to the debate on the alleged effectiveness of such economic incentives to actually change decisions among land users. Building on the standard PES theory of change, one would assume that farmers respond to payments and change their land use decisions accordingly for the delivery of environmental services. However, at the project level the impacts of economic incentives depend on how the signal is transmitted to decision-makers. An extensive household survey was undertaken among 270 participating farmers in order to investigate these assumptions. Results indicate that farmers join the scheme for intrinsic motivations rather than because of economic incentives. Besides, the scheme does not target farmers whose decisions could be changed for the sake of service provision. Finally, farmer group leaders display disproportionate power of decision while individual farmers have a low level of understanding of the PES programme. As a consequence, land use patterns might not depend on the economic incentive only; rather they are likely to be determined by the local social context, traditions and economic dependency on forests. This in turn casts some doubts on the strong (yet contested) economic assumptions that underlie the emergence of PES schemes and on their modus operandi in developing countries.     

Impact of local payments for ecosystem services on land use in a developed area of China: A qualitative analysis based on an integrated conceptual framework

Payments for ecosystem services (PES) have increasingly been applied as economic incentives for improving ecosystem services around the world. However, due to difficulties in measuring and attributing ecosystem services provisioning, a land-based approach has been popularly adopted as a proxy for the desired ecosystem services. In this study, we demonstrate the impact mechanism and outcomes of locally financed PES programs on conservation-based land use in a developed area of China. We present this work using a PES-land use proxy framework that is examined empirically through a variety of qualitative assessments. Our framework illustrates that, within the ecological, socioeconomic, and institutional conditions of developed areas, land use class, pattern and function would be impacted by (a) conservation effect, (b) stakeholder response, and (c) institutional adaptation mechanisms of local PES programs, with multiple land use trends as potential outcomes. We examine the framework using materials from Suzhou, China, which has implemented a top-down, partly involuntary (ecosystem services supply side), land based PES program. Our results show that, expected land use class, land use pattern and land use function are observed in areas where the PES programs were implemented. We also find that the conditions of developed areas and locally financed payments mechanism indeed played a crucial role in promoting conservation-based land use in Suzhou.     

Exploring the effect of land use on ecosystem services: The distributive issues

The current debate of ecosystem services has focused more on monetary valuation methods and payments for environmental services (PES) then on the classic economic analysis (i.e. assumptions regarding: sustainability, justice and efficiency). This paper examines, taking into consideration ecosystem services, income distribution from different land uses to stakeholders. We study the Portuguese common land ecosystem, which is characterized as having a wide range of ecosystem services. Allowing that all the benefits can be translated into economic value, we estimated the total economic value (TEV) associated with these territories on 5 different land use situations: forest, shrubland, water bodies, mountain agriculture and other uses, and analyzed the current institutional arrangements around these territories. We found that the distribution of the benefits of different land uses is relatively inequality. The results showed that the contemporary institutional arrangements of wealth distribution ensure a relatively fair distribution insider of system; however this institutional arrangement is unable to ensure equitable distribution of wealth by external stakeholders. We can conclude that different types of land use provide a very asymmetric distribution of income by different groups of humans: land owners; citizens of a country, and residents of Earth.

Notions of justice in payments for ecosystem services: Insights from China's Sloping Land Conversion Program in Yunnan Province

China's Sloping Land Conversion Program (SLCP) pays millions of farmers to convert cropland in upper watersheds to tree plantations. It is considered one of the world's largest payments for ecosystem services (PES) scheme for its reliance on financial incentives. This paper examines the outcomes of the SLCP by way of a case study from the Yangliu watershed in Yunnan province. It focuses on the notions of justice embedded in state policy and held by villagers and local state officials in order to understand the observed outcomes in terms of people's participation in the implementation of the SLCP, land use changes and livelihood effects. Villagers, local state officials, and state policy share a primary concern about distributive justice despite significant differences in their specific notions. The shared concern underlies the villagers’ positive reactions to the SLCP, which among other factors, have led to the intended expansion of tree plantations and a livelihood transition in Yangliu since 2003. The insights from Yangliu suggest the need to consider justice for a fuller understanding of the dynamics and outcomes of the SLCP and other PES schemes worldwide as the notions of justice applied by the involved actors may influence land use and livelihood dynamics in addition to the other factors considered in research this far.     

A factor-income approach to estimating grassland protection subsidy payments to livestock herders in Inner Mongolia,China

This paper contributes to the growing literature on land use policies designed to prevent livestock overgrazing. It offers a straightforward factor-income approach to calculating payments for ecosystem services (PES) to livestock producers who reduce or suspend grazing for the purpose of grassland restoration. Our approach requires only cross-sectional farm-level accounting data and is thus feasible where policies have either not yet been applied or specialized data is sparse, as is common in many developing regions. We apply and validate this approach with empirical analysis of sheep and goat herders in the Ulanqab prefecture in Inner Mongolia, China where herders currently receive payments in exchange for reduced grazing intensity on vulnerable land. However, observed stocking rates are still commonly higher than recommended. Our results suggest payments are currently insufficient to offset the financial loss incurred by herders who reduce their grazing intensity, a finding consistent with previous studies. Using an approach we refer to as the factor-income method, we estimate and validate new levels of recommended payments. This demonstrates how future payments could be tailored to meet the financial needs of individual herding communities using basic farm-level data.     

Effects of payments for ecosystem services programs in China on rural household labor allocation and land use: Identifying complex pathways

Payments for Ecosystem Services (PES) is increasingly used in developing countries to secure the sustainable provision of vital ecosystem services. The largest PES programs in the world are embedded in China’s new forest policies, which aim to expand forest cover for soil and water conservation and improve livelihoods of rural people. The objective of this study is to identify the complex pathways of the impacts of two PES programs , the Conversion of Cropland to Forest Program (CCFP) and the Ecological Welfare Forest Program (EWFP), on household livelihood decisions, and to quantify the direct and indirect impacts along the identified pathways. We fulfill this objective by developing an integrated conceptual framework and applying a Partial Least Squares-Structural Equation Model (PLS-SEM), based on household survey data from Anhui, China. Labor allocation (for on-farm work, local paid work, local business, or out-migration) and land use decisions (i.e., rent in, maintain, rent out, or abandon cropland) for participating households are key to understand PES program effects on livelihoods. Results show that the PES programs have only small direct effects but significant indirect effects via the mediating factor of capital assets. Moreover, group heterogeneity analysis shows that lower-income households do not benefit more than the better-off households from the PES programs, while households with medium wealth increase dependence on agriculture. In addition, household demographics, individual attributes, and geographic settings differ in their impacts on labor allocation and land use decisions. We conclude that CCFP and EWFP would be more efficient in conserving the environment while improving the economic welfare of lower-income households if capital assets were taken into account in the design of compensation schemes.     

Payments for environmental services to promote “climate‐smart agriculture”? Potential and challenges

Payments for environmental services (PES) have gained wide popularity as approaches to promote environmentally friendly land use or agricultural production practices. Yet academics have also voiced concerns against seeing PES as a panacea. This article discusses whether PES is an appropriate and promising approach to promote so‐called “climate‐smart agriculture” (CSA) practices, which we define as agricultural production practices that contribute to CO₂ emission reductions and/or removals and provide benefits to farmers via increased productivity and profits and reduced vulnerability to climate change. PES appears most promising for the promotion of CSA practices in small‐scale farming contexts with low incomes. Effective design, however, requires solid estimates of cost and benefit flows from CSA adoption over time, accounting for differences in socioeconomic and ecological conditions, and addressing the risk of leakage. Funding for such PES will likely have to come from public sources, and seems most promising where synergies with other objectives such as agricultural development, food security, and climate adaptation or other environmental services exist. The potential of alternative approaches for CSA support such as taxation with rebates for CSA practices, CSA‐related investment support such as microcredits, and hybrid approaches such as conditional microcredit should be further investigated.     

Policy lessons from spatiotemporal enrollment patterns of payment for ecosystem service programs in Argentina

Payment for ecosystem services schemes (PES) are lauded as a market-based solution to curtail deforestation and restore degraded ecosystems. However, PES programs often fail to conserve sites under strong long-term deforestation pressures. Underperformance, in part, is likely due to adverse selection. Spatial adverse selection occurs when landowners are more likely to enroll parcels with low deforestation pressure than parcels with high deforestation pressure. Temporal adverse selection arises when parcels are enrolled for short time periods. In both cases, financial resources are allocated without having a sizeable impact on long-term land use change. Improving program performance to overcome these shortcomings requires understanding attributes of landowners and their parcels across large scales to identify spatial and temporal enrollment patterns that drive adverse selection. In this paper, we examine these patterns in Argentina’s PES program in Chaco forest, a global deforestation hotspot. Our study area covers 252,319 km². Results from multinomial logistic regression models showed that large parcels of enrolled land and parcels owned by absentee landowners exhibit greater evidence of spatiotemporal adverse selection than smaller parcels or parcels owned by local landowners. Furthermore, parcels managed under land use plans for conservation and restoration are more likely to be associated with adverse selection than parcels managed for financial returns such as harvest of non-timber forest products, silviculture, and silvopasture. However, prior to recommending that PES programs focus on land uses with higher potential earnings, a greater understanding is needed of the degree to which these land uses meet ecological and biodiversity goals of PES programs. We suggest that increased spatial targeting of enrollment, along with enrollment of local landowners and further incentives for land uses that support conservation and restoration, could promote long-term conservation of forest lands.     

Institutional stakeholder participation in urban redevelopment in Tehran: An evaluation of decisions and actions

Experimentation with citizen participation in urban redevelopments is increasing worldwide. This paper aims to scrutinise this trend through an in-depth case study of the decisions and actions taken by the institutional stakeholders involved in participatory urban redevelopment in Tehran, Iran. The discussion is based around two contrasting urban redevelopment areas which set out to adopt a participatory approach involving various stakeholders including institutions (the Municipality of Tehran and the Heritage Organisation) and local owner-occupiers, developing new knowledge, understanding, and clarity about the concept and application of participation in urban redevelopments in developing countries. In both areas, the institutions invited owners to participate in the physical and economic improvements of their places through land assemblage or sharing redevelopment costs. In this study a range of qualitative methods are used including photo-elicitation techniques (PEI) and semi-structured interviews with locals, officials and professionals.The results show the vulnerability of the process. This was revealed when one institution did not maintain their role and when some owner-occupiers acted as free-riders. This highlights the challenge of building an enduring collaboration between institutional stakeholders from the planning to in-use stages, in particular the difficulties that arise as different institutions become involved in the process. This issue is more problematic when resources are limited and/or intermittent. As the results show, the institutional collaboration was smoother when fewer stakeholders were involved in decision making. In the commercial case, there were more complaints about overdue completion in the projects due to poor institutional collaboration. We recommend the need for an agreed mechanism prior to such initiatives where the role of the various stakeholders and their responsibilities are clearly cited, and where all different impact scenarios from the planning to in-use stage are set out.     

Participatory computer simulation to support collective decision-making: Potential and limits of stakeholder involvement

System models in agriculture and natural resource management are usually developed by researchers to advise policy makers on the likely outcomes of alternative scenarios. Except for data collection, stakeholders—like farm households—are rarely involved in the research process. Companion modeling (ComMod) has been developed as a modeling approach to include various stakeholders in a continuous feedback loop between researchers and stakeholders. Whereas other ComMod approaches have used role playing games as an interface between researchers and stakeholders—assuming that stakeholders have difficulties understanding a computer model—this paper explores the potential of a participatory modeling approach in which stakeholders are directly confronted with the model by assessing its assumptions, interpreting simulation results, and suggesting scenarios.The approach is applied to two villages in a watershed in northern Thailand. One lowland village, populated by farmers of mostly Thai ethnic origin, depends partially on an upland village inhabited by farmers of Hmong ethnic origin for its water supply. Water scarcity has led to conflicts between these two villages in the past.In three rounds of participatory simulation sessions the potential of the ComMod model was tested. Our findings confirm that researchers face particular challenges in making local stakeholders understand the model as a reproduction of reality and not as reality itself. The idea of a scenario as a hypothetical situation was also difficult to convey. An ex-post analysis among participants showed that farmers who attended several sessions had a clear understanding of the model and one-third of the participants thought it useful to exchange points of view with the other community and to define new collective rules for water sharing. Applying ComMod in a context that is characterized by social tensions and power differentials, however, needs careful consideration of the potential implications on less powerful actors.     

Prospective evaluation of the impact of land use change on ecosystem services in the Ourika watershed,Morocco

Land use change at the local stage affects the flow of ecosystem services at all levels. Analyzing the causes of land use change such as anthropogenic activities in the case of the Ourika watershed will facilitate sustainable policies. A decision-making tool, InVEST (Integrated Valuation of Ecosystem Services and Trade Offs) was used to quantify three ecosystem services and to generate three spatially explicit land use scenarios (trend, development and conservation) with expert stakeholders and the local population. The results indicate that forest expansion under the conservation scenario increased carbon sequestration and sediment retention by 34.29 % and 7.17 % but decreased water yield by 0.75 %. Comparably, a combination of forest and cropland expansion under the trend scenario generated a moderate increase by 8.4 % and 0.98 % but a negligible decrease of 0.09 %. A decline in the forests under the development scenario caused an improvement in the water yield by 0.12 % but a decrease in carbon sequestration and sediment retention by 6.06 % and 0.88 % respectively. A combination of forests and croplands through agroforestry systems enhances the provision of all the three ecosystem services. Community-based ecosystem and land management is the best way to improve ecosystem services at the local level.     

Future of the hills of Scotland: Stakeholders’ preferences for policy priorities

This paper sets out to assess stakeholders’ preferences for policy priorities for the management of the hill areas of Scotland, using an adaptive conjoint analysis (ACA) method. The method is used to evaluate trade-offs that stakeholders make between policy priorities. A pre-survey was carried out to obtain a large number of defining characteristics of a Scottish hill land system, which were subsequently narrowed down to 20 attributes. A survey was implemented, where a range of stakeholders, who had an interest in the hill and upland areas of Scotland, were asked to select and rank five attributes (out of the 20) that, for them, best described a hill system. They were also asked to describe what constituted both good and poor levels for each of their 5 chosen attributes. A computerised ACA questionnaire was designed, using attributes and levels defined from the previous surveys. Respondents were asked what the policy targets for management choices and options should be in the next 10 years for the Scottish hill areas. Policy simulations were subsequently carried out using the ACA software, to compare stakeholders’ actual preferences with seven different policy profiles, designed to reflect current land use issues and orientations for the Scottish hills.     

Changes in land use, land tenure, and landscape fragmentation in the Tijuana River Watershed following reform of the ejido sector

Changes in land use and land tenure can influence both physical fragmentation and ownership fragmentation of landscapes, with implications for biodiversity. In this study, we evaluated changes in land use and land tenure in the Tijuana River Watershed, a region of high biodiversity and endemism, following the implementation of a new Agrarian Law which allowed for privatization and sales of communal land (ejidos) beginning in 1992. In order to understand changes in land use and cover, we constructed maps from aerial photographs and Aster images and measured changes between 1994 and 2005. In order to understand changes in land tenure, we collected data from Mexican government sources on ejido land size, ownership, and sales, and we conducted 55 structured interviews with ejidatarios in the watershed. Our results demonstrate that land-use/cover change between 1994 and 2005 was dominated by an increase in urban area and grasslands, and a decrease in coastal sage scrub, chaparral, and, to a lesser degree, agriculture. In particular, the conversion of coastal sage scrub has left a far more fragmented landscape than existed in 1994. In addition, most of the ejidos in the watershed, as well as individuals interviewed, had participated in some stage of the land certification and titling process allowed by the new Agrarian Law, resulting in substantial changes in land tenure. However, land tenure security appeared to play a larger role than a desire to sell land and, contrary to studies from other regions, full title to the land was obtained in a range of urban and rural settings, rather than primarily on land closest to urban zones. Our results suggest that past predictions regarding future urban growth and fragmentation of native vegetation in the region have proven accurate and highlights regions of change that merit further study.     

An assessment of stakeholders’ participation in land use planning process of Luapula Province Planning Authority

The legal framework of Zambia has laws that support participatory land use planning process but there are no guidelines on how it should be done. Thus, the research aims at assessing if the Luapula Province Planning Authority (LPPA) has a land use planning process that incorporates effective stakeholders’ participation.The research is based on secondary data, especially the land use planning process in the Urban and Regional Planning (URP) Act No. 3 of 2015 of the Laws of Zambia and the participatory land use planning process of Kilimanjaro Region.The data analysed show that there is lack of effective stakeholders’ participation in the LPPA land use planning process; the LPPA land use planning process does not have the provision to capacity build stakeholders during the land use planning process; lack of participatory land use planning guidelines; the institutional framework under customary authority is not part of the land use planning process and the LPPA land use planning process is a top-down approach.The conclusions state that the legal and institutional frameworks in existence are inadequate for effective stakeholders’ participation in land use planning process of LPPA. In addition, the stakeholders are not incorporated in the LPPA land use planning process in terms of decision making but incorporated as reactants to the decisions made by the public authorities.The recommendations are that a National Land Use Planning Commission composed of representatives from stakeholder groups needs to be established. In addition, some sections of the URP Act No. 3 of 2015 of the Laws of Zambia need amendment inorder to have continuous feedback between the land use plan makers (planning firm(s) and planning authority) and the stakeholders. Furthermore, Village Councils must be given power to make decision by establishing them as Village Planning Authorities.     

An analytical approach with a reliable logic and a ranking policy for post-mining land-use determination

Because it is the post-mining land-use that prescribes the methods, the measures and the costs of mine reclamation, a major implicit goal of mine reclamation is to determine an after-use option. Therefore, there should be an analytical approach to optimize the determination of post-mining land-use. A Mined Land Suitability Analysis (MLSA) framework, which had been previously derived from reclamation practice reports of mines and other disturbed lands, is used in combination with two Multi-Attribute Decision-Making (MADM) techniques to provide the required analytical approach. In the proposed approach the decision makers consist of the most related experts and the identified stakeholders. The Analytical Hierarchy Process (AHP) method is used to determine global weights of MLSA framework attributes via pair-wise comparison matrixes composed by each individual expert. Once the global weight vector of the attributes is calculated using AHP, they are incorporated into the decision matrices composed by stakeholders and passed to the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), which is a distance-based MADM technique and is used to determine preference order of post-mining land uses.     

Mathematical optimisation of drainage and economic land use for target water and salt yields*

Land managers in upper catchments are being asked to make expensive changes in land use, such as by planting trees, to attain environmental service targets, including reduced salt loads in rivers, to meet needs of downstream towns, farms and natural habitats. End‐of‐valley targets for salt loads have sometimes been set without a quantitative model of cause and effect regarding impacts on water yields, economic efficiency or distribution of costs and benefits among stakeholders. This paper presents a method for calculating a ‘menu’ of technically feasible options for changes from current to future mean water yields and salt loads from upstream catchments having local groundwater flow systems, and the land‐use changes to attain each of these options at minimum cost. It sets the economic stage for upstream landholders to negotiate with downstream parties future water‐yield and salt‐load targets, on the basis of what it will cost to supply these ecosystem services.
