Applying Ostrom’s institutional analysis and development framework to soil and water conservation activities in north-western Ethiopia

Peer-reviewed publication
Janeiro, 2018
Etiópia

Sustainable land management is of utmost importance in Ethiopia and relies on Soil and Water Conservation (SWC) measures collectively implemented by smallholders through participatory processes. This paper contributes systematic evidence on how SWC strategies are implemented and how participation is operationalized.

Assessing the capacity and flow of ecosystem services in multifunctional landscapes: Evidence of a rural-urban gradient in a Mediterranean small island state

Peer-reviewed publication
Maio, 2018
Malta

Distinguishing between the ecosystems’ capacity to generate ecosystem services (ES) and the actual use of these service (ES flow) in ES assessment and mapping is important to develop an understanding of the sustainability of ES use. This study assesses the spatial variation in ES capacity and flow in the Mediterranean small island state of Malta. The services included in this study were crop provisioning, beekeeping and honey production, fodder and livestock production, crop pollination, air quality regulation, and aesthetic ES.

Trade-offs between high class land and development: Recent and future pressures on Auckland's valuable soil resources

Peer-reviewed publication
Junho, 2014
Nova Zelândia

Sustainable land management is essential to meeting the global challenge of securing soil and water resources that can support an ever increasing population. In Auckland, New Zealand's largest city, population growth is forecast to increase from 1.5 to 2.5 million by 2040 which will put immense pressure on the region's soil resources.

Stakeholder perceptions of the effectiveness and efficiency of agri-environment schemes in enhancing pollinators on farmland

Peer-reviewed publication
Agosto, 2015
Estados Unidos
Europa

In parts of the northern hemisphere, many pollinator species are in decline, with potential adverse implications for pollination and the ecosystem service of food production. It is therefore important to understand how habitats primarily orientated towards food production can be managed in an efficient way to enhance pollinator populations for current and future food security. In Europe, agri-environment schemes are a well-established method for promoting nature conservation on farmland.

Perceived importance of ecosystem services in the Białowieża Forest for local communities – Does proximity matter?

Peer-reviewed publication
Agosto, 2020
Global

Effective protection of biodiversity in areas of high conservation value requires trade-offs between local use of natural resources and conservation restrictions. The compromise is often difficult to reach, which causes conflicts over the management priorities of existing and potential protected areas. Ecosystem services (ES) perspective offers a promising avenue for diagnosing and reconciling contrasting interests concerning the use of benefits from ecosystems.

Effects of industrial plantations on ecosystem services and livelihoods: Perspectives of rural communities in China

Peer-reviewed publication
Março, 2017
China

This paper addresses the current research void on local community views of changes in ecosystem services associated with rapid land use transformation in the context of plantation-based forestry. This interview-based study, conducted in southern China, aims at assessing the perspectives of local communities of: 1) the effects of Eucalyptus industrial plantations on selected ecosystem services and on local development; and 2) opportunities for future community livelihood development, based on the relations with the government and with forest industry operating locally.

Agrarian transformation in Vietnam: land reform, markets and poverty

Journal Articles & Books
Dezembro, 2009
Vietnam

ABSTRACTED FROM INTRODUCTION: This paper traces the implications of key agrarian transformations −particularly the reforms in land policy and emerging land relations− for livelihood security and vulnerability. Part of a broader societal transformation and globalization of economies, these new development trajectories include commercialization of farmers’ produce, contract farming, cooperative sector reform, rising landlessness and tenant farming, and the end of exclusive dependence on land for earning a living.

Crop choice, farm income, and political control in Myanmar

Journal Articles & Books
Dezembro, 2008
Myanmar

Myanmar's agricultural economy has been under transition from a planned to a market system since the late 1980s and has experienced a substantial increase in production. However, little research is available on the impact of economic policies in this country on agricultural production decisions and rural incomes. Therefore, this paper investigates the impact using a micro dataset collected in 2001 and covering more than 500 households in eight villages with diverse agro-ecological environments.

The effects of land tenure policy on rural livelihoods and food sufficiency in the upland village of Que, North Central Vietnam

Journal Articles & Books
Dezembro, 2007
Vietnam

The paper documents how the implementation of the land tenure policy of the Vietnamese government has affected the agricultural system, livelihood strategies and food self-sufficiency of Thai farmers in a remote upland village, Que, in Nghe An Province, North Central Vietnam. It is shown that the enforcement of restrictions on the area under swidden agriculture has resulted in a strong reduction of swidden agriculture production and shortened fallow periods, not compensated for by the slow increase in paddy rice production.

Scenarios of land system change in the Lao PDR: Transitions in response to alternative demands on goods and services provided by the land

Journal Articles & Books
Dezembro, 2016
Laos

Sudden and gradual land use changes can result in different socio-ecological systems, sometimes referred to as regime shifts. The Lao PDR (Laos) has been reported to show early signs of such regime shifts in land systems with potentially major socio-ecological implications. However, given the complex mosaic of different land systems, including shifting cultivation, such changes are not easily assessed using traditional land cover data. Moreover, regime shifts in land systems are difficult to simulate with traditional land cover modelling approaches.

Land Acquisition, Investment, and Development in the Lao Coffee Sector: Successes and Failures

Journal Articles & Books
Dezembro, 2015
Laos

Despite the increasing acknowledgment of scholars and practitioners that many large-scale agricultural land acquisitions in developing countries fail or never materialize, empirical evidence about how and why they fail to date is still scarce. Too often, land deals are portrayed as straightforward investments and their success is taken for granted. Looking at the coffee sector in Laos, the authors of this article explore dimensions of the land grab debate that have not yet been sufficiently examined.

Fluid dynamics: Water, knowledge, and power in the Mekong Delta

Journal Articles & Books
Novembro, 2014
Vietnam

ABSTRACTED FROM THE FIRST TWO PARAGRAPHS: Over the past several years, the enormity of the environmental challenges facing the Mekong River Delta region of southern Vietnam has become increasingly clear. Climate change and dam construction on the upper reaches of the Mekong threaten to disrupt the flow of the river, making both droughts and floods ever more common. Meanwhile, the rapid intensification of rice agriculture in the Mekong Delta and the export-oriented cultivation of farmed fish and shrimp have increasingly strained.
