Farmer’S Perception

Abstract The Lake Toba Catchment Area (LTCA) has degraded due to a lack of implementation of conservation principles. Agroforestry is one of the land-use techniques with a conservation approach. Agroforestry development in LTCA should be supported by stakeholders, especially farmers. Farmers’ support will be formed if they have a good perception and interest in developing the agroforestry systems. The study aims to determine farmers’ characteristics, perceptions, and interests in agroforestry development in LTCA. The study was conducted from July until August 2019 at Simalungun Regency, North Sumatra Province. Data were collected through semi-structured interviews using a questionnaire with 30 respondents. Measurement of farmers’ perception and interest use a Likert scale. The data were then analyzed descriptively. The results showed that the farmers’ age is dominated by the productive phase (30-50 years old); they are only completed elementary schools, with average landholding was <0.3 ha, and farming experience >10 years. Farmers’ perceptions and interests in agroforestry development in LTCA are in good categories, each with a score of 4.18. These perceptions and interests of farmers are supporting factors that would positively impact the development of sustainable agroforestry in LTCA.

Negative Impacts

Afforestation programs are challenged by competition for land uses. Land use conflicts arise whenever there is divergent use, access and management of the resource or due to incompatible use and inadequate policy. Agroforestry may reconcile competing interests. However, small landholdings remain a challenge due to the negative ecological and economic impacts of most economically preferred trees for agroforestry systems.  Such negative impacts lead to the emergence of conflict among different land users and in most instances, slows down afforestation efforts on the farm. This study intended to explore conflicts arising from on-farm tree-planting and other land use practices, to identify the conflict resolution mechanism adopted by land users and to evaluate their strengths and weaknesses in conflict management. Mixed method approach of structured and semi-structured interviews was employed in Bobasi, Kisii County, Kenya. Content analysis, means, frequencies and cross-tabulations were done. Results indicated that small landholdings coupled with poor agroforestry practices were the main source of conflict driven by the ready market for trees of high economic values but with negative ecological impact. Conflict management mechanisms adopted were mainly cooperative methods such as voluntary negotiations between tree farmers and crop owners. These included adopting silvicultural control measures, benefit sharing of tree stems along the boundaries and compensation mechanisms for losses incurred by crop owners. Right based management mechanisms were also noted among other land users who believed that what they did with their land and compound was their business and so exhibited competitive approaches such as avoidance, coercion, and adjudication.

The Tehuacán-Cuicatlán Valley, Mexico, is the semiarid region with the richest biodiversity of North America and was recently recognized as a UNESCO's World Heritage site. Original agricultural practices remain to this day in agroforestry systems (AFS), which are expressions of high biocultural diversity. However, local people and researchers perceive a progressive decline both in natural ecosystems and AFS. To assess changes in location and extent of agricultural land use, we carried out a visual interpretation of very-high resolution imagery and field work, through which we identified AFS and conventional agricultural systems (CAS) from 1995 to 2003 and 2012. We analyzed five communities, representative of three main ecological and agricultural zones of the region. We assessed agricultural land use changes in relation to conspicuous landscape features (relief, rivers, roads, and human settlements). We found that natural ecosystems cover more than 85% of the territory in each community, and AFS represent 51% of all agricultural land. Establishment and permanence of agricultural lands were strongly influenced by gentle slopes and the existence of roads. Contrary to what we expected, we recorded agricultural areas being abandoned, thus favoring the regeneration of natural ecosystems, as well as a 9% increase of AFS over CAS. Agriculture is concentrated near human settlements. Most of the studied territories are meant to preserve natural ecosystems, and traditional AFS practices are being recovered for biocultural conservation.

AbstractEvaluation of land use/land cover (LULC) status of watersheds is vital to environmental management. This study was carried out in Jewha watershed, which is found in the upper Awash River basin of central Ethiopia. The total catchment area is 502 km2. All climatic zones of Ethiopia, including lowland arid (‘Kola’), midland semi-arid (‘Woinadega’), humid highland (Dega) and afro alpine (‘Wurch’) can be found in the watershed. The study focused on LULC classification and change detection using GIS and remote sensing techniques by analyzing satellite images. The data preprocessing and post-process was done using multi-temporal spectral satellite data. The images were used to evaluate the temporal trends of the LULC class by considering the years 1984, 1995, 2005 and 2015. Accuracy assessment and change detection of the classification were undertaken by accounting these four years images. The land use types in the study area were categorized into six classes: natural forest, plantation forest, cultivated land, shrub land, grass land and bare land. The result shows the cover classes which has high environmental role such as forest and shrub has decreased dramatically through time with cultivated land increasing during the same period in the watershed. The forest cover in 1984 was about 6.5% of the total catchment area, and it had decreased to 4.2% in 2015. In contrast, cultivated land increased from 38.7% in 1984 to 51% in 2015. Shrub land decreased from 28 to 18% in the same period. Bare land increased due to high gully formation in the catchment. In 1984, it was 1.8% which turned to 0.6% in 1995 then increased in 2015 to 2.7%. Plantation forest was not detected in 1984. In 1995, it covers 1.5% which turned to be the same in 2015. The study clearly demonstrated that there are significant changes of land use and land cover in the catchment. The findings will allow making informed decision which will allow better land use management and environmental conservation interventions.

As the capital of the province of East Kalimantan, Samarinda City developments has a rapid progress from year to year. Samarinda City Development has a tendency oriented towards infrastructure development without regard to the existence of the quality of the existing environment. Imbalance of development in Samarinda city is to start decreasing the water catchment area, so its make increasing intensity of flood in the Samarinda City. The purpose of this study was to analyze the impact of changes in land use in the Samarinda city on the ability of the water catchment area. This research method using descriptive approach, the data collection system of primary and secondary. Intensity flood in the Samarinda city  is increasing from year to year, this condition happened as a problem that always occurs during the rainy season. Current development trends, always take an area that should be an infiltration  area for Samarinda City. Culture and inadequate infrastructure conditions such as lack of system of drainage and polder, was another factor causing the high intensity of flood  in Samarinda City. Therefore, the relevant regulations development guidelines for Samarinda  City must consider all aspects of planning, in this case especially the important of a balance of cultivated land and protected areas or zones.Keywords: Changes in land use; intensity of puddles; Samarinda

Degree Of Participation

Civic participation has an irreplaceable role in the land-use planning process because it contributes a practical perspective to expert knowledge. This article discusses whether there is actually a level of civic participation that can be considered optimal, which would allow experts to effectively obtain information from everyday users of the territory, who have the best practical knowledge of it; experts may also gain sufficient feedback on intended developments, based on knowledge about civic participation from representatives of individual municipalities. The article also proposes measures that can promote an optimal degree of participation in the land-use planning process. The fieldwork was conducted in the form of semi-structured interviews with the mayors of municipalities with a population of up to 2000 inhabitants in selected districts of the Ústí Region (Czech Republic). The results suggest that the optimal degree of civic participation in land-use planning should have a representative extent, so it should not merely be a matter of individuals, but also one of groups of dozens of people, and such groups should encompass a balanced variety of characteristics; an optimal level of civic participation should also provide the maximum number of relevant impulses. Measures that may secure and foster an optimal degree of civic participation in land-use planning include (1) striving to avoid preferring purely voluntary participation; (2) simultaneously utilizing various tools to engage inhabitants; (3) educating inhabitants on a regular basis; and (4) consistently communicating and providing feedback, while also searching for informal means of communication and discussion.

Abstract. Litterfall is one of the major pathways connecting above- and below-ground processes. The effects of climate and land-use change on carbon (C) and nutrient inputs by litterfall are poorly known. We quantified and analyzed annual patterns of C and nutrient deposition via litterfall in natural forests and agroforestry systems along the unique elevation gradient of Mt. Kilimanjaro. Tree litter in three natural (lower montane, Ocotea and Podocarpus forests), two sustainably used (homegardens) and one intensively managed (shaded coffee plantation) ecosystems was collected on a biweekly basis from May 2012 to July 2013. Leaves, branches and remaining residues were separated and analyzed for C and nutrient contents. The annual pattern of litterfall was closely related to rainfall seasonality, exhibiting a large peak towards the end of the dry season (August–October). This peak decreased at higher elevations with decreasing rainfall seasonality. Macronutrients (N, P, K) in leaf litter increased at mid elevation (2100 m a.s.l.) and with land-use intensity. Carbon content and micronutrients (Al, Fe, Mn, Na) however, were unaffected or decreased with land-use intensity. While leaf litterfall decreased with elevation, total annual input was independent of climate. Compared to natural forests, the nutrient cycles in agroforestry ecosystems were accelerated by fertilization and the associated changes in dominant tree species.

The conversion of natural forest to agroforestry plantations and annual cropping systems alters the soil habitat and food resources for biota, including earthworms. Native earthworm species may disappear whereas exotic species with greater tolerance of disturbance and less niche specialisation may thrive. The objective of the study was to compare the earthworm diversity in managed forest and agroforestry systems, which were cultivated for mixed plantation and annual crop production on Mount Gede, Indonesia. All the habitats in the study area were impacted by humans. The forest habitat was a managed forest, with a permanent tree cover, whereas mixed plantation had a partial shrub cover. Meanwhile, homogenous plantation was cultivated with annual crops. Among 3787 individuals collected during July–October 2012, five Oriental earthworm species were identified in the soil communities of Mount Gede: Drawida nepalensis, Notoscolex javanica, Pheretima pura-group, Polypheretima moelleri, and Polypheretima sempolensis. Also, 18 species were found that are reported to be non-Oriental in origin. Anthropogenic disturbance of forests on Mount Gede, due to conversion into plantations, alters the earthworm environment by increasing soil water content, temperature and total phosphorous content, while decreasing organic carbon. N. javanica was the only native species to survive this deforestation, while the exotic Ocnerodrilus occidentalis and Pontoscolex corethrurus thrived, becoming the eudominant species. From the forest area to the mixed and homogenous plantations, the predicted decreasing diversity is evidenced by the lowering trend of Shannon’s diversity index. In conclusion, the land-use change into mixed plantations and annual croplands has reduced earthworm diversity in this region of Mount Gede, Indonesia.
