Will future tourism become sustainable?
Pellis, A. - \ 2019
sustainable tourism - sustainable development
Change is necessary, as it is unlikely tourism can continue to expand as it has been doing for the past decades. Maybe technology will solve some of the problems, but it is also important to stay critical and act on time. This lesson is part of the WageningenX MOOC called 'Sustainable Tourism: Society & Environmental Aspects'

Accountability - global - governance - integration - policy - sustainable development

The 17 Sustainable Development Goals and the full Agenda 2030 in which they are embedded are aspirational and intended to be both transformational and integrative in a number of ways. The need for integration across policy domains is stressed throughout the agenda. The Sustainable Development Goals are also accompanied by an emerging system for follow-up and review centered on a long list of indicators that are intended to enable countries to be accountable towards their citizens. There is, however, in the accountability literature indication that some accountability mechanisms can be counterproductive for integrative policies. This paper is centered around the question whether an accountability regime, and if so how, is compatible with a high degree of policy integration both conceptually and in the context of the Sustainable Development Goals. We approach this question through looking both at the literature on integrative governance and some of the central concepts it covers such as (environmental) policy integration and mainstreaming, and the accountability literature. This enables us to provide an analytical framework for evaluating the potential of the emerging accountability regimes for the Sustainable Development Goals to enhance more integrated policy making and action. We conclude that there are little or no strong hierarchical elements of accountability relationships at the global level which can be good news for more integrative policies – but only if there is a strong sense of shared responsibility among actors at all levels, available information on the types of behavioural efforts that support integration, and accountholders that take an active interest in integration. At the national level, there may be hierarchical accountability mechanisms with sanction possibilities that may discourage integration. Here, those who hold actors to account can counteract this if they have deeper understanding of the underlying interlinkages among the goals and targets, and based on this, engage in accountability mechanisms.

Green Deals zijn vrijwillige afspraken tussen de Rijksoverheid en maatschappelijke partijen om innovatie en verduurzaming te bevorderen. Met deze aanpak geeft de overheid ruimte aan vernieuwing vanuit de maatschappij. Maar wat leveren Green Deals nu eigenlijk op? Partijen blijken warm te lopen voor samenwerking en vernieuwing. Maar wat mist is het vooraf goed doordenken van de ver wachte milieuwinst en het moni- toren er van tijdens de uitvoering van deals. Door meer richting te geven, zowel aan het begin als aan het einde van individuele deals, kan de Rijksoverheid bevorderen dat de Green Deals verder bijdragen aan maatschappelijke doelen.

De Stichting Stadsvarkens te Ede wil weten aan welke regelgeving moet worden voldaan om vier varkens in een bosperceel te houden en te voeden met reststromen. Het doel is het sluiten van kringlopen binnen een circulaire economie. Dit rapport gaat in op de wet- en regelgeving rond diervoeding en op de afzet van het vlees in de setting van Stadsvarkens. Daarnaast wordt het voeren van reststromen in relatie tot diergezondheid belicht. Door studenten is binnen een ACT-traject gekeken naar relevante wetgeving en is een viertal scenario’s geschetst voor het houden van stadsvarkens die gevoerd worden met lokale reststromen. De scenario’s zijn door de onderzoekers tegen het licht gehouden en van kanttekeningen en een advies voorzien. Dit heeft geresulteerd in een ander advies, omdat verschillende knelpunten de eerdere scenario’s niet mogelijk maken.

One of the major challenges facing global society today is the provision of food, water, energy, healthcare and other resources & services in a world characterised by increasing population, mounting environmental stresses and rising inequality. There is a need for circular and resilient food systems which close material flow loops in the entire supply chain from farm ers to consumers and back. This should be done in a resource-efficient manner that includes all relevant actors. This position paper summarises insights by Hans van Meijl, Stijn Reinhard and Ruerd Ruben from Wageningen Economic Research into what has been dubbed the inclusive and sustainable economy. Therefore, five overarching challenges, five scoping issues, and five beneficial economic principles are discussed. In addition, the authors formulate five key insights regarding feasible policy strategies and attempt to contribute to the analysis of leverage points relevant to upscaling and to anchoring market innovations that sustain sustainable and inclusive agri-food systems.

Duurzaam bosbeheer (Sustainable Forest Management: SFM) is van groot belang voor de duurzame instandhouding van het bosareaal met de bijbehorende biodiversiteit en ecosysteem diensten zoals hout productie, opslag van koolstof en recreatie. Voor de bescherming van bossen en functies zijn in diverse internationale fora afspraken gemaakt over SFM. Nederlandse regering heeft de afspraken om SFM te stimuleren in het kader van deze fora onderschreven en uitgewerkt in het beleid. Vanwege de vele verdragen, programma’s en afspraken ontbreekt momenteel een overzicht van acties die in Nederland daadwerkelijk invulling geven aan (internationale) afspraken over SFM . Om te kunnen verantwoorden hoe Nederland zijn internationale afspraken heeft geïmplementeerd hebben beleidsmakers bij de rijksoverheid behoefte aan meer inzicht in het aantal en het soort implementatieacties met betrekking tot SFM van de Nederlandse bossen . In deze studie wordt met een quick scan een globaal overzicht gegeven van implementatie acties waarmee de Nederlandse Rijksoverheid invulling geeft aan de internationale afspraken voor SFM in het Forest Europe - proces met betrekking tot bossen en bosbeheer in Nederland .

Biomimicry , de ontwerpfilosofie die de natuur als inspiratiebron ziet voor innovaties, kan grote ecologische en economische voordelen opleveren voor onze samenleving wanneer het bre ed wordt ingezet ten behoeve van maatschappelijke en wetenschappelijke vraagstukken. Het biedt ook veel toepassingsmogelijkheden voor een groot aantal sectoren , zoals bouw, industrie en landbouw . Om aan een kennisinfrastructuur voor biomimicry te kunn en werken, is het van belang om te weten welke kennis diverse partijen in ons land in huis hebben, welke ze willen delen en welke kennislacunes er zijn. Deze kennisagenda is met dat doel opgesteld. De kennisagenda agendeert een aantal vraagstukken voor de komende periode waaraan betrokken stakeholders in onderlinge samenwerking gericht kunnen werken om de toepassing van biomimicry in ons land de komende jaren op een hog er plan te brengen. Deze kennisagenda geeft daarmee richting aan biomimicry -innovaties die de komende jaren (wellicht) met voorrang opgepakt worden.
Answering the "Call of the Mountain" : co-creating sustainability through networks of change in Colombia

In response to the age of the ‘anthropocene,’ as some authors are calling this epoch in which one single species is disrupting major natural systems (Steffen et al 2011), there are calls for more radical, learning-based sustainability that generates deep transformations in individuals and communities so as to transition towards a more reflexive and process-oriented society (Wals 2009, Sterling 2009). The principal contention of this thesis is that new social movements (NSM) of the network society (Castells 2012, Buechler 2016), based on integrated visions of sustainability, can provide platforms for bringing about transformative learning. This thesis is based on empirical research (2012-2016) into a fraction of such NSM named the Council of Sustainable Settlements of Latin America (C.A.S.A.). Comprising a diversity of members from Indigenous pueblos, afro-colombian communities, neo-rural settlements (ecovillages), Hare Krishna communities, campesino farmers, NGOs and urban peoples and initiatives, the C.A.S.A. network organizes intercultural exchanges where transformative learning can be traced. Through new forms of collective action centered on a plurality of ideas and practices, and with a strong focus on reflection and personal development, in such encounters through ‘ontological politics’, ‘optimal dissonance’ and ‘deep reflexivity and flexibility’ members are articulating new paradigms of alternative development and creating spaces for transformation. Yet, such learning processes are incredibly complex, and the value-action gap remains substantial in many cases. What this thesis has shown, however, is that by putting into practice principles of buen vivir and the pluriverse such as reconnecting to ancestral wisdom, acknowledging the other, questioning values of competition and consumerism, and forming new relations to place and territory, one begins to question one's own set of norms, and those of society. Ultimately, the C.A.S.A. network’s struggles, negotiations and learning processes remind us that global sustainability entails more than 'menus' of good practices but a plurality of solutions which include humans and non-humans, different ontologies, and even a multiplicity of worlds, in what is a tough but rewarding aula.

Een circulair voedselsysteem is méér dan sluiten van kringlopen

Een circulaire economie draait, kortweg, om het sluiten van kringlopen, en kent vooral milieutechnologische en logistieke benaderingen als kennispijlers. Maar een circulaire economie heeft evenzeer een sociaaleconomische invulling nodig. Hoe populair het tegenwoordig ook is in de beleids- en onderzoekswereld om voorstander te zijn van de circulaire economie, de vorming ervan vereist een fundamentele omslag. Attentie mag er daarom zijn om de animo waarmee vandaag de dag de noodzaak van een circulair voedselsysteem wordt bepleit te verbinden aan de animo waarmee werk wordt gemaakt van de condities waaronder deze transitie kan gedijen.

Sub-Saharan Africa countries face the challenge of reducing rural poverty and reversing the declining trends of agricultural productivity and the high levels of soil nutrient depletion. Despite of numerous efforts and investments, high levels of poverty and resource degradation persist in African agriculture. The Millennium Development Goals Report (MDGR) states that the majority of people living below the poverty line of $1.25 a day belong to Sub-Saharan Africa (SSA) and South Asia. About two thirds of the global rural population lives in mixed crop-livestock systems (CLS), typical of SSA, where interactions between crops and livestock activities are important for the subsistence of smallholders. CLS are characterized by high degree of biophysical and economic heterogeneity, complex and diversified production system that frequently involves a combination of several subsistence and cash crops and livestock. Increasing crop productivity is clearly a key element to improve living standards and to take these people out of poverty. However, agricultural productivity in most of SSA has been stagnant or increased slowly. In addition, the likely negative impacts of climate change on agriculture have accentuated the vulnerability of smallholders.

The international research community has once more the eyes on SSA with the recently proposed post-2015 MDGs, the Sustainable Development Goals that emphasize the need to achieve sustainable development globally by 2030 by promoting economic development, environmental sustainability, good governance and social inclusion. Governments and scientists are making considerable efforts to develop strategies that include structural transformations of the different sectors of the economy in search of the recipe to achieve the SDGs. Most of these strategies are based on policy and technology interventions that seek to achieve the “win-win” outcomes and move from the usual “tradeoffs” between poverty-productivity-sustainability to synergies. A key message of this thesis is that achieving the goal of sustainable development in semi-subsistence African agriculture will require better understanding of the poverty-productivity-sustainability puzzle: why high poverty and resource degradation levels persist in African agriculture. I hypothesize that the answer to this puzzle lies, at least in part, in understanding and appropriately analyzing key features of semi-subsistence crop-livestock systems (CLS) typical of Sub-Saharan Africa. The complexity and diversity of CLS often constrain the ability of policy or technology interventions to achieve a “win-win” outcome of simultaneously reducing poverty while increasing productivity sustainably (i.e., avoiding soil nutrient losses).

This thesis focuses on the Machakos Region in Kenya. Machakos has been the center of many studies looking at soil fertility issues and its implications for poverty and food security, including the well-known study by Tiffen et al. (1994). Recently, the Government of Kenya developed the Kenya Vision 2030, a long-term development strategy designed to guide the country to meet the 2015 MDGs and beyond. The agricultural sector is recognized as one of the economic actors that can lead to reduce poverty if appropriate policies are in place. For the Vision 2030, the key is to improve smallholder productivity and promote non-farm opportunities. The Vision 2030 was used to assess if the implementation of some of the proposed plans and policies can lead to a sustainable agriculture for smallholders in the Machakos region.

This thesis describes and uses the Tradeoff Analysis Model (TOA), an integrated modeling approach designed to deal with the complexities associated to production systems such as the CLS and at the same time, quantify economic and sustainability indicators for policy tradeoff analysis (e.g., poverty indexes and measures of sustainability). The TOA was linked to Representative Agricultural Pathways and Scenarios to represent different future socio-economic scenarios (based on the Vision 2030) to assess the impacts of policy interventions aimed to move agricultural systems towards meeting sustainable development goals.

One important finding is that the complex behavior of CLS has important implications for the effectiveness of policy interventions. The Machakos analysis provides important findings regarding the implementation and effectiveness of policy interventions addressing poverty and sustainability in Africa and other parts of the developing world. The analysis shows that policy interventions tend to result in much larger benefits for better-endowed farms, implying that farm heterogeneity results in differential policy impacts and that resilience of agricultural systems is likely to be highly variable and strongly associated with heterogeneity in bio-physical and economic conditions. The results shows that a combination of these interventions and strategies, based on the GoK Vision 2030 and the Machakos County plans, could solve the poverty-productivity-sustainability puzzle in this region. The pathway from tradeoffs to synergies (win-win) seems to be feasible if these interventions and strategies are well implemented, however the analysis also shows that some villages may respond better to these strategies than others. The analysis suggests that these interventions may actually benefit most the areas with better initial endowments of soils and climate.

The analysis also suggested that prices (e.g., maize price) play a key role in the assessment of policy interventions. There is an increasing recognition that analysis of economic and environmental outcomes of agricultural production systems requires a bottom-up linkage from the farm to market, as well as top-down linkage from market to farm. Hence, a two-way linkage between the TOA model and a partial equilibrium market model (ME) was developed. The TOA model links site-specific bio-physical process models and economic decision models, and aggregate economic and environmental outcomes to a regional scale, but treats prices as exogenous. The resulting TOA-ME allows the effects of site-specific interactions at the farm scale to be aggregated and used to determine market equilibrium. This in turn, can be linked back to the underlying spatial distribution of economic and environmental outcomes at market equilibrium quantities and prices. The results suggest that market equilibrium is likely to be important in the analysis of agricultural systems in developing countries where product and input markets are not well integrated, and therefore, local supply determines local prices (e.g., high transport costs may cause farm-gate prices be set locally) or where market supply schedules are driven not only by prices but also by changes in farm characteristics in response to policy changes, environmental conditions or socio-economic conditions. The results suggest that the market equilibrium price associated to a policy intervention could be substantially different than the prices observed without the market equilibrium analysis, and consequently could play an important role in evaluating the impacts of policy or technology interventions.

As mentioned above, climate change poses a long-term threat for rural households in vulnerable regions like Sub-Saharan Africa. Policy and technology interventions can have different impacts under climate change conditions. In this thesis the likely economic and environmental impacts of climate change and adaptations on the agricultural production systems of Machakos are analyzed.

Climate change impact assessment studies have moved towards the use of more integrated approaches and the use of scenarios to deal with the uncertainty of future condition. However, several studies fall short of adequately incorporating adaptation in the analysis, they also fall short of adequately assessing distributional economic and environmental impacts. Similarly, climate change is likely to change patterns of supply and demand of commodities with a consequent change in prices that could play an important role in designing policies at regional, national and international levels. Therefore, a market equilibrium model should also be incorporated in the analysis to assess how markets react to changing prices due to shifts in supply and demand of commodities. The TOA-ME was used to incorporate the elements mentioned above to assess the impacts of climate change. Using data from 5 Global Circulation Models (GCMs) with three emission scenarios (SRES, 2000) to estimate the climate change projections, these projections were used to perturb weather data used by a crop simulation model to estimate the productivity effects of climate change. Land use change and impacts on poverty and nutrient depletion at the market equilibrium were then assessed using the TOA-ME model.

The simulation was carried out for three scenarios, which are a combination of socio-economic and climate change scenarios: a baseline scenario that represents current socio-economic conditions and climate conditions, a climate change and current socio-economic scenarios (i.e., future climate change with no policy or technology intervention), and a climate change and future socio economic conditions which are a consequence of rural development policies.

Our findings show that in this particular case, the changes on precipitation, temperature and solar radiation do not show a significant difference among the selected emission scenarios. However, the variability is significant across GCMs. The effects of climate change on crop productivity are negative on average. These results show that policy and technology interventions are needed to reduce this region’s vulnerability. Furthermore, the socio-economic scenarios based on policy and technology interventions presented in the case study would be effective to offset the negative effect of climate change on the sustainability (economical and environmental) of the system across a range of possible climate outcomes represented by different GCMs. Finally, the results show that ignoring market equilibrium analysis can lead to biased results and incorrect information for policy making, in particular for the scenario based on policy and technology interventions.

One of the major conclusions of the thesis are that policy interventions aimed to deal with poverty and sustainability can have unintended consequences if they are not accompanied by a set of policy strategies and investments. For example, increasing the maize price can result in substitution from subsistence crops to maize, without much increase in nutrient inputs, thus increasing soil nutrient losses. The analysis shows that improving soil nutrient balances by increasing fertilizer and manure use is critically important, but is not enough to move the system to a sustainable path.

There is no one factor that can reverse the negative nutrient balances and move the system towards sustainability. Rather, a broad-based strategy is required that stimulates rural development, increases farm size to a sustainable level, and also reduces distortions and inefficiencies in input and output markets that tend to discourage the use of sustainable practices. The Machakos case shows that a combination of these interventions and strategies, based on the GoK Vision 2030 and the Machakos County plans, could solve the poverty-productivity-sustainability puzzle in this region.

Globally, bio-based business is often perceived as sustainable, because its renewable production can potentially lower carbon and greenhouse emissions by substituting fossil-fuel-based production, reduce environmental sourcing problems, and create turnover and jobs. However, bio-based business can also bring sustainability challenges. Urged to exploit innovative solutions and further enhance their sustainability performance, organizations engaged in bio-based activities extensively search for collaboration possibilities with new partners. Inter-organizational collaboration is considered as mechanism to enhance sustainability. This thesis explores the ways inter-organizational collaboration in bio-based business in general and in agro-industrial parks in particular can enhance sustainability.

Cross-sectoral strategies in global sustainability governance: towards a nexus approach

nexus - sustainable development - global governance - policy integration
The recent shift from the Millennium Development Goals to the much broader Sustainable Development Goals has given further impetus to the debate on the nexus between the multiple sectors of policy-making that the Goals are to cover. The key message in this debate is that different domains—for instance, water, energy and food—are interconnected and can thus not be effectively resolved unless they are addressed as being fully interrelated and interdependent. Yet while this overall narrative is forcefully supported in the new UN 2030 Agenda for Sustainable Development and the 17 Sustainable Development Goals that are the main part of this agenda, many Goals still remain sectoral in their basic outlook. This now requires, we argue, a new focus in both policy and research on the nexus between different Sustainable Development Goals, especially with a view to reforms in the overall institutional setting that is required to sufficiently support such a nexus approach. This article thus examines the nexus approach in the context of the Sustainable Development Goals and identifies multiple avenues for its institutionalisation in global governance.
Kansen voor toepassing van microalgen in landbouwgewassen

Op basis van internationaal literatuuronderzoek blijken er interessante kansen voor toepassing van microalgen producten in landbouwgewassen te zijn. In dit rapport worden zowel groene algen als cyanobacteriën gedefinieerd als microalgen. Stoffen uit microalgen (met name uit cyanobacteriën) blijken in diverse onderzoeken uit de literatuur een goede bestrijding te geven van verschillende schimmels en aaltjes die in landbouwgewassen schade aanrichten. Verder is er (buiten de landbouw) insecticide-, molluscicide-, herbicide- en algacidewerking met stoffen uit cyanobacteriën aangetoond. In Nederland zijn zeewier- en algenextracten krachtens de Verordening gewasbescherming als werkzame stof goedgekeurd voor de groeiregulatie van planten. Het gebruik als bodemverbeteraar of als plantenstimulator is vooralsnog veel minder gereguleerd dan als gewasbeschermingsmiddel. Om de kansen met microalgen te benutten zou er verder geïnvesteerd moeten worden in onderzoek. Het zou duidelijk moeten worden welke werkzame stoffen uit micro algen of welke algenpreparaten andere organismen bestrijden, in welke formulering en met welke dosering. De bestrijdende, bemestende, bodem verbeterende, plantweerstand verhogende en milieueffecten van algentoepassingen zouden vergeleken moeten worden met conventionele methoden.
