Socio-economic determinants of best land management practices adoption in highly anthropized areas: case study of Dan Saga and Tabofatt village clusters in Niger republic

The objective sought by this study is to highlight the socio-economic determinants that could be helpful in scaling up of best land management practices in high demographics areas. Indeed, a survey was carried out in Dan Saga and Tabofatt two villages’ clusters in order to identify the driver factors which explain the high adoption of best land management practices in these areas. The data were collected from 200 farmers (100 from each cluster), randomly chosen. The survey addressed the likelihood of farmer to use agroforestry practices and or erosion control practices, on the basis of four socioeconomics variables: the educational level of farmer (Instr), the distance between their farm and habitation (Prox), the possession of Harnessed Cultivation Unit (HCU) and the land tenure status (Land). Data were subjected to an analysis by statistical modeling of logistic regression. The results show that agroforestry technology is predominated in Dan Saga cluster (90% of citation for agroforestry practices) compare to Tabofatt cluster where people use mostly erosion control practices (76% of citation for erosion control practices). Among the socioeconomics variables, three main factors significantly influenced the adoption of best land management; the educational level of peasants, the modality of land tenure by purchase and by inheritance and the possession of harness unit. In addition, the main land management technologies perform a high profitability compare to state of inaction. These results could serve as a lever for scaling up of regreening policy in other degraded areas of Sahel’s region.

Land is one of the potential natural resources to be developed optimally to increase local revenue. Based on the availability of water, land is grouped into two major groups, which are wetland and dry land (upland). The use of dry land for agriculture is often ignored by policy makers. Problems in dry land management vary in each region, both technical and socio-economic aspects. However, with the right strategy and technology, these problems can be overcome. Efforts to manage dry land to increase food production face problems, including steep slopes, low soil fertility, and water shortages. These problems need to be overcome by applying the right technology. Dry land management technology is available, including management of soil fertility, soil conservation, land rehabilitation, and efficient management of water resources. The problem is the weak dissemination of innovative technology to farmers and the slow adoption of this technology. Utilization of dry land to increase food production requires appropriate planning and strategies.

The use of mulch and amelioration in peatlands to increase production of red chili plants

Red chili is a strategic commodity, production consistency in quality and quantity is needed. Peatland with all its limitations has the potential to be used as an area for chili crop development, but appropriate land management technology is needed. The purpose of this study was to determine the effect of using mulch and amelioration and fertilization for chili plants in peatlands during the rainy season. The research was conducted at Landasan Ulin, Banjarbaru. The treatments were: The use of mulch (without mulch and silver black plastic mulch) and a combination of inorganic and amelioration fertilizer doses (P1 = 50% model of inorganic fertilizer + 15 t ha−1 manure), P2 = 50% model of inorganic fertilizer + 30 t manure ha−1), P3 = Model 100% Inorganic Fertilizer + Manure 15 t ha−1), P4 = Model 100% Inorganic Fertilizer + Manure 30 t ha−1, P5 = Farmer Model. The results showed that the use of black silver mulch combined with 325 kg ha−1 urea, 225 kg ha−1 SP 36 and 200 kg KCl kg ha−1 KCl and 30 t ha−1a manure showed fruit yields of chili plants reached 15 t ha−1.

Land suitability evaluation according to agroecological zone information for agricultural commodity development in coastal area of Tegal Central Java Indonesia

The Agroecological Zone (AEZ) is an information system to determine the potential of land resources. Based on that, the suitability of plants and their land management technology can be identified. The evaluation of land suitability of coastal areas in Tegal District was carried out using matching method between growing requirements for commodities and land characteristics of AEZ data. AEZ identification results show that the coastal area consists of three zones, namely Zone A, alluvial plains with Typic Endoaquepts and Aeric Endoaquepts soil types; Zone B, Fluvio-marine plains with Typic Endoaquepts soil types; and Zone C, coastal areas with Typic Udipsamments soil types. Based on the agroecological characteristics, the coastal area is suitable for crops development and fisheries. The suitable agricultural commodities namely rice, water melon, sugar cane and jasmine, which correspond to class 1 (S1) for zones A and B; red chilies and shallots, class 2 (S2) which is suitable for zones A and B. While zone C is identified as less suitable for food crops or horticulture, due to limiting factors such as poor oxygen availability and poor root conditions.

The Effect of Participation in Farmer Groups on Household Adoption of Sustainable Land Management Practices in Kenyan Drylands

Land degradation is a major cause of declining yields and loss of dryland ecosystems resilience in the Lake Baringo Basin in Kenya. One of the solutions to land degradation in drylands is the application of Sustainable Land Management (SLM) technologies. Improving farmers’ capacity to adopt SLM technologies has been an important strategy of the Kenyan government and her development partners to addressing land degradation. State agricultural extension services are charged with the role of building this capacity. Unfortunately, such extension services have had little impact in the Kenyan drylands. To counter this inadequacy in extension services, farmers have formed grass-root organisations to foster networks of support and information sharing. In this paper, we analysed the effect of participation in farmers organisation in promoting adoption of SLM practices by agropastoralists in the Lake Baringo Basin. Data were collected through in-depth household interviews with 150 farmers, 79 of them group members and 71 non-group members. Level of knowledge, sources of information and challenges of SLM adoption were studied. The study revealed significant and positive association between group participation and adoption of SLM practices at X2 (3, N=150=63.209, P=0.000). Additionally, group partnering with development agencies like Non-Governmental Organisations (NGOs) and government departments was reported to have significant influence on household adoption of SLM practices at X2 (3, N=79=13.147, P=0.004). The results indicated that farmer groups can effectively be used to leverage farmers' adoption of SLM innovations and potentially improve household income and food security in the Kenyan drylands. We recommended organizational and resource capacity building for farmer groups to promote their effectiveness in provision of resources and services to their members. In addition, government research and extension agencies and academia should consider forming collaborations with farmer groups in generation of SLM technologies that are suited to the farmers location and prevailing context.

Land-property and land-resource information obtained as a result of land management

The article deals with issues related to the creation of digital land management based on the use of modern information technologies. The creation of digital land management is carried out in close connection with the digitalization of agriculture and other sectors of the economy. The basis of information support for land management is the state data Fund, which is formed on the basis of land management documentation, materials and data (in written, graphic, electronic, photographic and other forms) obtained as a result of land management. In addition, information support for land management includes scientific and technical products and modern information systems that allow developers and consumers of land management documentation to provide up-to-date, complete and visual information about the results of land management works and technologies for their implementation. These issues are closely related to the regulation of the entire structure of the country’s land service, land legislation and, in General, the development of an optimal land policy, on which information support and full interaction of the entire land management industry depend.

The influence of food security on sustainable land management technologies of farming households in Kwara State, Nigeria

Suboptimal land management practices (SLM) are degrading soils and undermining food security. Despite this, there is scant information regarding households’ decision towards the effect of food security on SLM technologies. This paper, therefore, measured food security status and assessed the effect of food security on SLM technologies. Structured interview schedule was used to gather data for this study. A three-stage sampling procedure was employed for this study. Two out of the four ADP zones were randomly selected in the first stage. This was followed by a proportionate selection of 30 villages from the two selected zones. Lastly, ten farming households each, were picked randomly from the chosen villages to make up a sample size of 300 farming households. The result revealed that the calculated MPCFE was ₦4218.587 and the proportion of food secure and food insecure households are 37.7% and 62.3% respectively. The findings affirmed that much opportunities exist for increasing productivity and income through increased adoption of SLM technologies among the food insecure households when compared with their food secure counterparts. The R2 value of 29.8% suggests that the explanatory variables explained about 30% of the variation in the explained variable. Furthermore, the factors influencing SLM technologies of households are food security status, family size, monthly income and plot size. This study provides useful insight into policies and actions taken by farmers and government to mitigate the effects of suboptimal use of SLM technologies for improved production and food security. Policies favoring increased plot size should be vigorously pursued.

Climate change continues as a threat to smallholder farmers in Northern Ghana, which is arid in nature and prone to draught conditions. Sustainable Land and Water Management (SLWM) technologies have been introduced to smallholder farmers in the area as adaptation strategies to mitigate the negative effects of climate change. Adoption of the SLWM technologies have the potential of reducing the negative impact of climate change, and also improve crop yield. There is a death in knowledge in understanding factors that influence the uptake of the SLWM technologies in Northern Ghana. The study therefore, examined the factors influencing SLWM technology uptake in Northern Ghana. The study was undertaken among 300 smallholder farmers in the three Northern Regions of Ghana through a multi-stage sampling technique. Data were gathered through a survey and a Poisson model was employed to assess the drivers and intensity of adoption. Results showed that factors such as support received, labour, water availability, exposure, access to information and farm size influenced the uptake of the SLWM technologies. The study recommends that policy makers should work towards improving the factors that influence the uptake of the SLWM technologies. It is also important to adopt private-public partnership model in the implementation of the SLWM technologies.

The potential of intercropping citrus and rice to improve the productivity of swamp land in Indonesia

Appropriate and integrated land management technology in utilizing swamp land with optimal and sustainable productivity is needed because the swamp ecosystem is naturally fragile. The development of intercropping rice and citrus on tidal land needs to be supported by the application of cultivation technology and institutional strengthening of farmers so that the results obtained can be optimum and sustainable. Common problems that arise in the use of tidal land for agriculture include a variety of overflow and inundation conditions, very diverse types of soil with varied and low fertility levels, soil acidity and high potential for pyrite toxicity, variety of peat thickness and maturity level, and the condition of farmers who are still weak both in terms of skills and capital. This paper discusses the intercropping potential of citrus and rice to increase the productivity of swamps in Indonesia, the environmental and technical constraints, and strategies in proper and integrated land management.

Survey data on factors that constrain the adoption of soil carbon enhancing technologies in Ethiopia

The data described in this paper were collected in two watersheds – Azuga-suba watershed in Angacha woreda (district) of Southern Nations, Nationalities and Peoples (SNNP) region and Yesir watershed of Bure woreda (district) of the Amhara region – in Ethiopia. The data were collected from 379 households with the main objective being to assess the factors constraining the adoption of sustainable land management technologies (SLMT) that enhance soil organic carbon sequestration. The data were collected using a structured questionnaire that was designed in SurveyCTO. The data cleaning and analysis was done using STATA SE version 14. This data can be used by researchers to assess the extent of adoption of SLMTs in Ethiopia by, for example, comparing the North and the South regions of Ethiopia. It can also be used to assess the probability of adoption as well as the benefit and costs of adopting SLMTs in Ethiopia both at farm and plot level.

Sustainable development in East Africa: impact evaluation of regional agricultural development projects in Burundi, Kenya, Rwanda, Tanzania, and Uganda

AbstractInvestments in agricultural technologies, capacity building and policy harmonization are needed to support sustainable development across Africa. Regional development projects can facilitate the adoption of agricultural technologies and innovations across nation‐state borders and generate benefits for shared prosperity. This paper uses panel data from 1,160 smallholder households including beneficiaries and non‐beneficiaries from five countries in East Africa ‐ Burundi, Kenya, Rwanda, Tanzania, and Uganda. From a pool of over 90 projects implemented over a span of 15 years, 23 regional projects are included in this study. The major economic benefits to smallholder participants are higher crop productivity and income, access to adaptable technologies, access to markets, higher livestock and milk production, gender equality, enhanced food security, resilience and capacity building for uptake and scaling up of future innovation platforms. For example, the adoption of low‐cost tissue culture banana by the beneficiaries increased their incomes by 15% in Rwanda while the adoption of appropriate land and water management technologies increased the potato yields from 2.8 tons (USD 2,840/ha) to over 7.5 tons (USD 7,410/ha) in Kenya. The beneficiaries ensured value added to commodities like bananas (for export) and orange‐fleshed sweet potatoes (a nutrition‐sensitive intervention for enhancing domestic intake of vitamin A) in Burundi, Kenya, Rwanda and Uganda. Additionally, milk production increased from 6 to 11 L per cow per day in Uganda and from 6 to 8 L per cow per day in Tanzania, with increases in sales generating USD 115 per cow per month above the non‐beneficiaries. These results are supported by previous studies on technology adoption, investments in agriculture and well‐being outcomes. Our findings with the higher farm income Difference‐in‐Differences (DiD) estimator for the female beneficiaries compared to male beneficiaries might have important implications for investing in regional development projects that will close the gender gap in agricultural productivity in Africa. Regional projects can also support post‐conflict development efforts for food security and peace in fragile contexts such as in Burundi. Our findings might serve as an input to the African Union's Comprehensive Africa Agriculture Development Programme, localization of the United Nations Sustainable Development Goals related to food security and agriculture in Africa and an input to monitoring, evaluation and learning.

Validation of land management information system model (SILAHAN) on plot scale, case study in Citaman, Nagreg, West Java

Upland has potential uses for agriculture practices in indonesia. However there are some problems to manage, one of them is many existing upland in sloping areas and high risk to erosion and runoff. Indonesian Soil Research Institute developed a recommendation model for the land management information system (SILAHAN) based on the study of criteria for soil conservation indicators with calculation of erosion hazard index and surface runoff. The aim of this study was to validation SILAHAN prediction models from surface runoff aspects on a plot scale as the basis for formulating recommendations for the most complex land management technology. Validation of the prediction results of surface runoff in SILAHAN model is done by comparing surface runoff results of real measurements in field with the results of predicted by SILAHAN with three simulation. The results of statistical tests with r pearson correlation coefficient is 0,31, 0,31, and 0,32, PBias is -90,6, -86,6 and -83,5, and NSE is -0,76, -0,68, and -0,63. The results of the prediction of plot scale surface runoff in the SILAHAN model were not same as the measurements result on the field observations. it is suggested to determine the correction factors and development capabilities of the SILAHAN model to assess the effectiveness of a land management system in reducing the amount of surface runoff.

The effect of sustainable land management technologies on farming household food security in Kwara state, Nigeria

Nigeria is among countries of the world confronted with the food insecurity problem. The agricultural production systems that produce food for the teeming population are not sustainable. Consequently, the use of Sustainable Land Management (SLM) technologies becomes a viable option. This study assessed the effect of SLM technologies on farming households? food security in Kwara State, Nigeria. A random sampling technique was used to pick 200 farming households for this study. The analytical tools included descriptive statistics, Shriar index, Likert scale, food security index and logistic regression analysis. The results indicated that the average age of the respondents was 51.8 years. The food security index showed that the proportions of food secure and insecure households were 35% and 65% respectively. The binary logistic regression revealed that SLM technologies were one of the critical determinants of food security. An increase in the usage of SLM technologies by 0.106% raised food security by 1%. Other important factors that were estimated included farm income, family size, gender and age of the household head. To reduce the effects of food insecurity, the effective coping strategies adopted by the respondents were reduction in quantity and quality of food consumed, engaging in off-farm jobs to increase household income and using of money proposed for other purposes to buy foods. Governments at all levels should encourage the adoption and use of SLM technologies through both print and electronic media. Policies and strategies towards reducing the household size should be vigorously pursued to reduce food insecurity.
