Property Rights and Natural Resource Management Incentives: Do Transferability and Formality Matter

Journal Articles & Books
декабря, 2008
Philippines

This article examines how property rights expectations affect resource management incentives. It utilizes expected property rights over different timespans and of different strengths, corresponding to (a) investments of different intensities and (b) farmers' sense of security regarding their often de facto property rights. The results suggest that property rights and their alienability in ten-year time matter to intensive infrastructural investments, although not to lighter investments.

Farmer's Adoption of Rotational Woodlot Technology in Kigorobya Sub-County of Hoima District, Western Uganda

Journal Articles & Books
декабря, 2008
Uganda

This paper evaluates, using logistic and multiple regression analyses, the socio-economic factors that influence farmers’ decisions to adopt rotational woodlot technology in the farming systems of Uganda, based on a household survey carried out between May and December 2004, involving 120 farmers in Kigorobya sub-county, Hoima district. The analyses demonstrate that farmers make decisions about woodlot technology based on the household and field characteristics.

alternative approach to sustainable water users' organization in national irrigation systems: the case of the Khlong Thadi Weir System, southern Thailand

Journal Articles & Books
декабря, 2008
Thailand

Thai national irrigation systems, serving a large number of small paddy farmers, require water users' organization for effective and sustainable joint management; however, water users' organizations (WUOs) presently cover only 27% of the total irrigation area. This three-year action research investigated the difficulties in organizing water users in the Khlong Thadi Weir System in southern Thailand by immersion into the socio-economic conditions of Muslim farmers in farm turnout No. 4 of the 1L-4R-LMC canal and the conventional on-farm irrigation development there.

method to define a typology for agent-based analysis in regional land-use research

Journal Articles & Books
декабря, 2008
Netherlands

Land use/cover change (LUCC) is often the cumulative result of individual farmer's decisions. To understand and simulate LUCC as the result of local decisions, multi-agent systems models (MAS) have become a popular technique. However, the definition of agents is not often based on real data, ignoring the inherent diversity of farmers and farm characteristics in rural landscapes. The aim of this paper is to describe an empirical method that defines an agent typology and allocates agents into the different agent types for an entire region.

Land-use and cover changes (1988-2002) around budongo forest reserve, NW Uganda: implications for forest and woodland sustainability

Journal Articles & Books
декабря, 2008

Land-use and cover changes around Budongo Forest Reserve (BFR) were analysed from multi-temporal LandSat images (1988 and 2002) and associated field-based studies in 2003-2004. Three major land-use and cover classes: forest/woodland, sugarcane plantations and grassland/shifting-cultivation/settlements were clearly discriminated. The area under sugarcane cultivation increased over 17-fold, from 690 ha in 1988 to 12729 ha in 2002, with a concomitant loss of about 4680 ha (8·2 per cent) of forest/woodland, mainly on the southern boundary of BFR.

Fuelwood, deforestation, and land degradation: 10 years of evidence from cebu province, the Philippines

A major development concern of the 1970s and 1980s was 'the other energy' or 'woodfuel crisis'. Woodfuel use in developing regions of Africa, Asia, and Latin America was believed to be a key factor in tropical deforestation, and the loss of forests was projected to result in widespread woodfuel shortages. In recent years, however, it has become apparent that woodfuel production is seldom a direct cause of deforestation (although it may be a by-product), and that most woodfuel demand is met by trees and shrubs growing outside of forest areas.

Erosion modelling approach to simulate the effect of land management options on soil loss by considering catenary soil development and farmers perception

Journal Articles & Books
декабря, 2008

The prevention of soil erosion is one of the most essential requirements for sustainable agriculture in developing countries. In recent years it is widely recognized that more site-specific approaches are needed to assess variations in erosion susceptibility in order to select the most suitable land management methods for individual hillslope sections. This study quantifies the influence of different land management methods on soil erosion by modelling soil loss for individual soil-landscape units on a hillslope in Southern Uganda.

Evolving more sustainable agriculture in the Cameron Highlands, Malaysia

Malaysia

Smallholders in many tropical highlands cause serious environmental damage. The Cameron Highlands of Malaysia offer an excellent opportunity for studying how farmers interact with environment, changing markets, infrastructure development, indigenous peoples, and tourism, and how these shape innovation. Our surveys in 2002-2004, 2006 and 2007 show that farmers have intensified production and in doing so some have adopted less damaging practices. We assess trends and causation of changes; this offers opportunities for more proactive management.

Adoption potential of fruit-tree-based agroforestry on small farms in the subtropical highlands

Journal Articles & Books
декабря, 2008
Guatemala

Worldwide, fruit-tree-based agroforestry systems have been only modestly studied, although they are common on smallholder farms. Such systems based on apple (Malus spp.), peach (Prunus spp.), and pear (Pyrus spp.) are common in northwest Guatemala as low intensity homegardens and are known to increase total farm productivity in communities where farm size is a limiting factor.

Hanfets, a barley and wheat mixture in Eritrea: Yield, stability and farmer preferences

Eritrea

Hanfets is a popular mixture of wheat and barley grown in the highlands of Eritrea and Tigray (Northern Ethiopia). In this study, we tested 16 experimental hanfets constituting all possible combinations of four barley landraces and four wheat (two landraces and two varieties) at three locations in Eritrea for 3 years during which farmers (both men and women) made selections of suitable hanfets. Across locations and years, the grain yield of hanfets on average was similar to that of the pure barley but significantly higher than that of wheat.
