Land Uses

We analyzed the agricultural land-use changes in the coastal areas of Tien Hai district, Thai Binh province, in 2005, 2010, 2015, and 2020, using Landsat 5 and Landsat 8 data. We used the object-oriented classification method with the maximum likelihood algorithm to classify six types of land uses. The series of land-use maps we produced had an overall accuracy of more than 80%. We then conducted a spatial analysis of the 5-year land-use change using ArcGIS software. In addition, we surveyed 150 farm households using a structured questionnaire regarding the impacts of climate change on agricultural productivity and land uses, as well as farmers’ adaptation and responses. The results showed that from 2005 to 2020, cropland decreased, while aquaculture land and forest land increased. We observed that the most remarkable decreases were in the area of rice (485.58 ha), the area of perennial crops (109.7 ha), and the area of non-agricultural land (747.35 ha). The area of land used for aquaculture and forest increased by 566.88 ha and 772.60 ha, respectively. We found that the manifestations of climate change, such as extreme weather events, saltwater intrusion, drought, and floods, have had a profound impact on agricultural production and land uses in the district, especially for annual crops and aquaculture. The results provide useful information for state authorities to design land-management strategies and solutions that are economic and effective in adapting to climate change.

Planning And Management

The aim of this study was to investigate the effects of land degradation on agricultural land use, planning and management in Kalama Division, Machakos County; and specifically determined farmers’ considerations of land suitability for selected types of agricultural land uses in varying cropping zones, investigated farmers’ local environmental knowledge of land degradation indicators and finally documented farmers’ land management strategies and practices for soil and water conservation. Data was collected using a questionnaire, along a road transect cutting across upper, middle and lower zones (parts) of a slope. A total of 40 households along the transect on the three zones were interviewed. Results obtained revealed that crop farming, livestock, poultry, farm forestry and bee keeping were the major agricultural land use activities carried out in the study area. Overall, steep slope was the most important factor considered for farm forestry (17%) (5.29 STDEV). Bee farming was the least land use practice accounting for only 1% of total land use. Most land degradation (15%) was reported in the middle zone while lowest land degradation (7%) was reported in the upper zone. The study found out that most households were aware of land degradation indicators in their local environment and described them using their indigenous environmental knowledge. The smallholder farmers prevented further land degradation by use of their local or traditional ways such as application of organic manure, planting of trees, crop rotation, use of gabions and stone lines. Different zones had different land use and management practices due to differences in terrain and other physical and biophysical characteristics. Overall, the major land management practices included tree planting (23%) (4.04 STDEV) and water conservation and gabion making (10%) (2.52 STDEV). This study clearly established an existence of smallholder farmers’ indigenous knowledge, perceptions, and beliefs of the local environmental factors of land condition which are necessary for the farmer’s decision-making on land use planning and management. On the basis of these findings, the study argues for place-based analysis and understanding of the landscape structure and local micro-environments in enhancing understanding of local-level decision-making on land use planning and management by smallholder farmers in maintaining livelihood security. Even though the study is limited to the local scope, it can provide a basis for designing policies aimed at rural livelihood security improvement and inform and facilitate targeting of outside interventions such as land use planning and management programs which can be built on existing indigenous knowledge.

Central and Eastern Europe has experienced fundamental land use changes since the collapse of socialism around 1990. We analyzed the patterns and determinants of agricultural land abandonment and recultivation in Slovakia during the transition from a state-controlled economy to an open-market economy (1986 to 2000) and the subsequent accession to the European Union (2000 to 2010). We quantified agricultural land-use change based on available maps derived from 30-m multi-seasonal Landsat imagery and analyzed the socioeconomic and biophysical determinants of the observed agricultural land-use changes using boosted regression trees. We used a scenario-based approach to assess future agricultural land abandonment and recultivation until 2060. The maps of agricultural land use analysis reveal that cropland abandonment was the dominant land use process on 11% of agricultural land from 1986 to 2000, and on 6% of the agricultural land from 2000 to 2010. Recultivation occurred on approximately 2% of agricultural land in both periods. Although most abandoned land was located in the plains, the rate of abandonment was twice as high in the mountainous landscapes. The likelihood of abandonment increased with increased distance from the national capital (Bratislava), decreased with an increase of annual mean temperatures and was higher in proximity to forest edges and on steeper slopes. Recultivation was largely determined by the opposite effects. The scenario for 2060 suggests that future agricultural land abandonment and recultivation may largely be determined by climate and terrain conditions and, to a lesser extent, by proximity to economic centers. Our study underscores the value of synergetic use of satellite data and land-use modeling to provide the input for land planning, and to anticipate the potential effects of changing environmental and policy conditions.
