4. Understanding socio-ecological drivers of fuelwood dynamics and their impact in Churia hills of Nepal

Author

Abstract

Forests in developing countries are under tremendous pressure because of increasing dependence of human communities on timber, fodder, non-timber forest products, and fuelwood. Nepal’s forests approximately cover 40% of its total geographical area, which experiences very high human dependence. In the present study, we propose an innovative approach of coupling socio-ecological attributes in Kayarkhola watershed in Churia hills of Nepal using remote sensing datasets and field observations to understand the patterns of fuelwood dynamics. Using multi-temporal moderate resolution satellite datasets, we have analyzed the patterns of land use and land cover change from 1990 to 2010 and assessed the effectiveness of community forestry management. The socio-ecological coupling provided quantification of most significant drivers of fuelwood dynamics. We observed low forest loss in community forests in comparison with those falling outside community forests. We conclude that family size, income levels, and percentage of illiterate persons are the most significant individual factors, whereas these factors along with the availability of agricultural land, supply of alternative energy sources are significantly inversely related drivers controlling the fuelwood dynamics. The scenarios developed in this study can be extrapolated in different landscapes to quantify the fuelwood dynamics, which will help in better forest cover management and conservation.

Abstract

To illuminate future uncertainties and inform strategic plans, this chapter presents three qualitative scenarios for the status of the HKH through 2080. The scenarios (Box 4.1) emerged from a participatory visioning exercise for scenario development (also see Sect. 4.1.2) conducted by the chapter team and HIMAP secretariat between January and September 2016. Over six successive workshops, decision makers and scientists representing HKH countries determined what would constitute a “prosperous” HKH scenario for 2080—along with its less desirable alternatives, business as usual and downhill (Fig. 4.1).

Abstract

The paper presents a multifunctional inverter for a three-phase single-stage gridconnected Solar Photo-Voltaic System (SPV) system with Enhanced Phase Locked Loop (EPLL)-based control algorithm. The EPLL-based Quadrature Signal Generation (QSG) estimates the magnitude of source voltage and load current signal and Phase-Locked Loop (PLL) estimates phase angle of the grid voltage. This estimation is used to design a proper controlled algorithm which improves the power quality such as reactive power compensation, harmonic rejection and DC offset rejection, in addition to feeding the SPV energy to load and grid. Perturb and Observe (P&O)-based Maximum Power Point Tracking (MPPT) is used to estimate the reference PV voltage signal and power. The EPLL-based controller tracks the signal even under distorted grid supply conditions such as voltage sag/swell and harmonics to improve the dynamic response. These multifunctional capabilities of the inverter make the system more efficient for feeding the SPV energy to grid. Various operating conditions are shown to validate the proposed controlled algorithm using MATLAB/Simulink. [ABSTRACT FROM AUTHOR]
