Water erosion causes significant economic losses linked mainly to the silting up of dams and losses in soil productivity, these consequences will increase if soil and water conservation actions associated with development actions are not undertaken. The present work aims to evaluate the water erosion in the basin of the Beni Boufrah located in the Northern part of Morocco. The hierarchy of this basin in plot according to the degrees and the tendencies of the erosion was made using the qualitative PAP/CAR approach (Programme d’Actions Prioritaires/Centre d’Activités Regionales) which is based on the integration of the factors influencing the water erosion, such as the slope, lithology and/or pedology, vegetation cover and land use. This work was conducted in three stages, the first one being predictive based on the analysis of the natural factors influencing water erosion and the processing of databases of developed maps. The second so-called descriptive stage is based on the mapping of different forms and processes of soil loss that occur in the study area. The last step, it allows the integration and the combination of the results of the two previous steps. Its purpose is to provide a precise cartographic product that reflects the reality of the state of soil degradation and the future evolution of erosion. The consolidated erosion map shows that more than half of the basin area (53%) is affected by medium-level erosion, 13% is affected by high erosion level, and 15 % is affected by low-level water erosion. Low-intensity erosion occurs along the river in areas where the slope and lithology favour runoff. The trend map is the final result of the integration phase, it describes erosion trends in the different parts of the basin and is, therefore, a tool to guide decisions on land use planning and tillage methods to limit the risk of water erosion in the basin. Keywords: Oued Beni Boufrah, water erosion, PAP/CAR, erosive states, erosion trend.

Telagawaja Sub-Watershed is upper part watershed of Unda Watershed. As upper watershed, Telagawaja sub watershed has functions as conservation area, water catchment area, and managed in order to keep sub watershed environment not degradated. This research objectives are to identify the characteristics of the land, the function of the area, and the erosion potential rate (TBE), as well as land management recommendations on Telagawaja Sub-Watershed. The identification of land is conducted by analyzing the characteristics of thematic maps in study area. The directives of classification land function is determined by the Minister of Agriculture Number.837/Kpts/Um/ 11/1980 and Number: 683/Kpts/Um/8/1981. The prediction of actual erosion is calculated by USLE formula for the agriculture area, while non-agricultural land use is applied Snyder formula (1980) in Asdak (2010). Erosion class and erosion rate (TBE) are determined based on the Director General of Reforestation and Land Rehabilitation Department of Forestry Number.041/Kpts/V/1998. Determination for the amount of erosion is still can be allowed using the method of Thompson (1957) in Arsyad (2010) which based on soil properties attached to Telagawaja sub watershed. The research shows that Telagawaja Sub-Watershed characteristic is an area which is susceptible to erosion.The analysis shows that the direction of the area function Telagawaja sub-watershed consists of an area of 7337.28 Ha of protection forest (66.01%), and the function of a buffer area 3.778.31 Ha (33.99%). The result of the study on Telagawaja sub-watershed erosion is 2777.07 tonnes ha-1year-1. Erosion class and erosion rate of Telagawaja Sub-Watershed vary from very light to very severe. Erosion class and erosion rate (TBE) with category severe to very severe consist an area of 2.071,97 ha (18,64 %) from total sub-watershed area. Land use planning implemented by applying alternative measures of soil and water conservation can reduce the rate of erosion of 2777.07 tonnes ha-1year-1 to 611.00 tonnes ha-1year-1 or less 2166.07 tonnes ha- 1year-1.

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.

The Relationship

Abstract Land use planning is defined as the regulation of the relationship between space and human activities. Space occupied by human settlements, farmland and forests, parks, fallow land, rivers and lakes, and by transportation networks constitutes a network of areas dedicated to land uses such as agriculture, forestry, rangeland, industry, mining, recreation, and fishing. Land use planning is a comprehensive and long-term approach to planning human relations and their activities in space; it is the task of regulating and coordinating the strategies and general orientations of sectors, and it is the foundation of economies and human activities. The purpose of land use planning is to achieve an optimal distribution of economic and social activities. Land use selection and management are commonly done without regard to the carrying capacity of the land which, when exceeded, results in economic losses and in a reduction of environmental quality. The overall goal of land use planning is to achieve the optimal use of the land within the national interest framework. Accordingly, formulating a successful plan for managing the development of a country requires proper attention to the roles of geography and land use. Creation of a suitable balance between the Earth and its use by human activities can be achieved by proper land management. The increasing importance of environmental issues and human alteration of natural environments calls for sustainable development and land use practices that conserve natural resources while benefiting society and the environment. Nowadays, due to many factors such as climate change, population growth, changing standards of living, poverty, access to education, and mismanagement of natural and water resources, there is a need to diversify food and agricultural production in a variety of ways. Overseas cultivation is one of them, and it has potential for improving agricultural production. The practice of overseas cultivation by a country means planting and harvesting of a variety of agricultural products in other countries to be sold in its domestic market or in foreign markets. There are five basic principles that underline the success of overseas cultivation involving any group of countries: (1) mutual respect for the governance of all countries; (2) making and abiding by agreements between the countries; (3) non-interference in the internal problems of each country and respect for the territorial integrity of all countries; (4) optimal use of human resources and capacities to support agricultural activities and trade; and (5) expanding security and military cooperation.

The response of hydrologic circulation to climate and land use changes is important in studying the historical, present, and future evolution of aquatic ecosystems. In this study, the Coupled Model Inter-comparison Project Phase 5 multi-model ensemble and a raster-based Xin'anjiang model were applied to simulate future streamflows under three climate change scenarios and two land use/cover change conditions in the Xinjiang Basin, China, and to investigate the combined effect of future climate and land use/cover changes on streamflow. Simulation results indicated that future climate and land use/cover changes affect not only the seasonal distributions of streamflow, but also the annual amounts of streamflow. For each climate scenario, the average monthly streamflows increase by more than 4% in autumn and early winter, while decreasing by more than −26% in spring and summer for the 21st century. The annual streamflows present a clear decreasing trend of −27%. Compared with land use/cover change, climate change affects streamflow change more. Land use/cover change can mitigate the climate change effect from January to August and enhance it in other months. These results can provide scientific information for regional water resources management and land use planning in the future.

The comment indicated that landed wealth (acres owned) should be included as an explanatory variable in the zoning referendum estimation. Land can be construed as an indicator of wealth that may be impacted by land use controls. The reply focuses on study site issues as well as theoretic, empirical, and institutional/social considerations. Responses to land use control referenda depend on the land considered, attitudes toward land use planning and socio-demographic factors, including income. The amount of acres owned was not statistically significant in explaining preferences for land use controls in the case investigated by McLeod, Woirhaye and Menkhaus.

Pidie is one of the districts in Aceh Province that has been suffering from flooding. Frequent disasters, especially flooding associated with various causative factors, need mitigation efforts. An appropriate land use planning by considering the risk aspects especially in flood is an important step. Objectives of this study are to determine the factors influencing the flood hazard, to map the areal distribution vulnerable to flood, to analyze the relations of land use in the flood hazard area, and to analyze the relations between the planned spatial pattern and the flood hazard area. ,Multicriteria analysis was used to determine the factors influencing the flood hazard. Spatial analysis was used in mapping the class of flood hazard, the relations of land use in the flood hazard area, and the relations between the planned spatial pattern and the flood hazard area. The results show that the main factors influencing flood vulnerability are land use/cover (0.408), rainfall (0.266), and slope (0.184). Based on the classification of flood vulnerability, the area can be divided into more vulnerable (37.75 %), less vulnerable (30 %), and mildly vulnerable (22.76 %). The vulnerability classes of the land use/cover are: less vulnerable (99.99 %) and more vulnerable (97.57 %) dominated by forest cover; mildly vulnerable (51.07%) and vulnerable (92.65%) dominated by mixed farming; and very vulnerable (97%) dominated by settlement. The flood vulnerability of the planned spatial pattern can be classified as follows: 95.44 % of the conservation area is dominated by less vulnerable and more vulnerable, while 71.20 % of the cultivation area can be categorized into mildly vulnerable, vulnerable and very vulnerable.

Temporal And Spatial Distribution

Land degradation by soil erosion has called attention in tropical developing countries, particularly when natural vegetation is converted to farmland. Thus, the occupation of Brazilian savannas in Western Bahia is a matter of growing environmental concern. There are approximately 10 million hectares affected by this relatively recent land-use dynamics, but little is known about the temporal and spatial distribution of the process. To better understand such transformations, this paper addresses three related topics: land use/land cover (LULC) in 1985 and 2000; LULC dynamics between 1985 and 2000; and risk of land degradation by soil erosion as a function of farming expansion. The study area is located in Northeastern Brazil, between the coordinates 11º S and 46º 30' W and 14º S and 43º 30' W. All classes of natural vegetation cover decreased their areas during the period of study. Savanna (cerrado) lost 21.0% of its original area. Modern farming and irrigated areas increased 154.4 and 526.0%, respectively. Farming expansion reached 1,675,233 ha. Moderate risk of land degradation by soil erosion increased from 28.0 to 36.8% of the landscape mosaic between 1985 and 2000. The spatial and temporal dynamics observed reproduces development and land degradation examples of other savanna lands in Brazil. The integrity of native vegetation cover and the dissemination of soil and water conservation practices should be considered. This research contributes with an understanding of landscape transformations as a baseline for strategic environmental and land-use planning within the region.

Cities nowadays are the most significant source of environmental degradation threatening local and global ecosystems. Interestingly, many ancient settlements present excellent lessons and inspiration for addressing our current urban predicaments, given their environmental stewardship. This research explores how the ecologically embedded settlement patterns, building configurations, urban agriculture and home gardening, and water conservation of the Maya-built environment can offer insights about mitigating contemporary urban sustainability challenges. Mayans’ respect for nature not only guaranteed sustainable habitats but also engendered one of the most remarkable civilizations in a region that did not offer generous support for human accommodation. The Mayan world view promoted the idea of one spirit dwelling in all humans and other-than-human entities in an environment, making everything sacred and kin to everything else. The regional climate was kept under control by protecting the vegetation that also provided other ecological benefits. Land use was mixed, and residences were constructed with native and recyclable materials utilizing natural light and ventilation. The Mayan civilization inspires us to manage and protect plants, not cut them down; conserve water, not waste it; listen to the environmental feedback, not reject it; and, most importantly, it begs us to embrace nature as our own mother, not disown it as something dispensable. These principles have significant implications on urban land-use planning and policies today.

Hierarchy Process

Despite the large number of studies on natural hazards mapping and modeling, an increasing number of disasters still occur worldwide. Floods, landslides, and tsunamis, among others, consistently hit vulnerable countries, resulting in increasing death tolls and economic losses in the last decades. The increased reliability of available hazard maps is still insufficient when not fully integrated and incorporated in the respective communities' land use plans. As a pro-active and preventive approach in combatting disasters, land use planning requires the relevant stakeholders' active participation. This study derives the most crucial criteria in the eyes of planners, experts, and decision-makers for natural hazards mapping as part of land use planning and part of disaster risk reduction. These stakeholders and experts establish criteria for flood, landslide, earthquake and storm surge hazard mapping through Multi-criteria Evaluation (MCE). The MCE technique compares the relative merits of different spatially related criteria following the Analytic Hierarchy Process (AHP) through pair-wise comparisons of criteria by experts and the decision-makers. This research process derives a general and consistent list of criteria for hazard mapping initially developed and based in the Philippines, which can be used in subsequent GIS analysis. Results further show the advantages of using AHP in a multi-criteria analysis for decision-making and compliance.

Twenty-two typical pedons (14 soil series- TTK1 to TTK-14) representing major landforms of Tatrakallu village of Ananatapuramu district of Andhra Pradesh were evaluated by using qualitative and quantitative methods. Three major land capability classes (III, IV and VI) were identified with two sub classes (erosion and wetness). Crop suitability analysis revealed that the village falls under marginally suitable (S3) with limitations of soil fertility, wetness and sodicity and not suitable (N) with limitations of slope, texture shallow rooting depth, sodicity and poor nutrient status. Riquier’s parametric approach was found to be good indicator for identification of production potential. The land evaluation revealed that, suitability and productivity of these soils were highly variable, and hence their management must be site-specific. The suggestion including the crop residue retention, nutrient recycling, minimum tillage, crop rotation, cover crops and intercropping not only helps to conserve soil and water more effectively in soils but also increase organic matter content and improve fertilizer use efficiency. Farmers continued to grow groundnut, pigeonpea, chickpea and castor for many years on marginally suitable as they are not aware of suitable soils for a particular crop. Adoption of suggested ameliorative measures and land use not only improve the yield but also sustain the soil productivity.
